PROJECT DESCRIPTION: The applicant, Southport West LLC, is requesting Master Plan Review, Hearing Examiner
Site Plan Review and Environmental (SEPA) Review for the construction of Southport West. Southport West is the
completion of the southerly portion of the Southport Development located at the south end of Lake Washington Blvd N.
The proposed expansion of Southport would be located on the 10.09-acre former Puget Sound Energy (PSE) Substation
and PSE utility parcels (APNs 082305-9191 and -9178). The two (2) parcels are located in the Urban Center-2 (UC-2) zone
and the Urban Design District ‘C’. The site is proposed to be developed as five (5) high-rise buildings with approximately
1,200,000 square feet of office and 50,000 of retail development in multiple phases. The proposed first three phases
would be developed as follows: Phase I – Towers 1 and 2 with the garage podium (July 2023 – July 2027), Phase II –
Towers 3 and 4 with garage podium (July 2027 – July 2031), and Phase III – Tower 5 (post July 2031). Phases 1-3 would
start on the south side of the site (closer to Boeing) and would develop to the north side of the lot (closer to Gene Coulon
Memorial Beach Park). A fourth and final phase is being considered for a sixth tower with 130,000 square feet for office
and retail at the south corner of the development near the intersection of Park Ave N and 757th Ave NE. The phased
development could reach as high as 1.6 million gross square feet. The proposed nine-level development would be built
at the same height and scale as the existing Southport offices with an overall height of approximately 154 feet above
average grade. Parking for 2,207 vehicles would be provided in a shared 4- and 5-level parking garage and 57 spaces are
proposed as on-street parking. In addition, the applicant is proposing to work closely with PSE for the engineering and

capacity needs of the development in order to relocate the powerlines and utility switchgear adjacent to Johns Creek.
Vehicular access to Southport West would be provided by Park Ave N, Lake Washington Blvd N, and the addition of an
internal center road and frontage road.
The site is generally level and consists of gravel yard and asphalt, a Puget Sound Energy switchgear, and an
office/warehouse building. The site contains high seismic hazard areas and the northeast corner of the site contains
Johns Creek and regulated slopes. The soil consists of a loose to medium dense sand, underlain by soft to medium dense
silt, then medium dense to dense sand, very soft silt and clay, and finally dense to very dense silty sand. Groundwater
was observed in the historical exploration at Southport at depths ranging from 3 to 10 feet below existing grade.
Preliminary estimates of cut and fill include approximately 25,000 cubic yards of excavation and 39,200 cubic yards of fill
from an approved source. The depth of excavation is anticipated to not exceed approximately two feet (2’) below ground
level, except for building cores where excavation would be deeper. Stormwater runoff from pollution generating surfaces
would be captured by catch basins and treated in cartridge filter facilities prior to connection into three (3) existing
drainage systems. No significant trees are proposed to be removed. Southport is proposing to plant 115 new trees along
with a variety of shrubs and perennials. The applicant has submitted a Preliminary Geotechnical Report, Technical
Information Report, Traffic Impact Analysis, and Stream Assessment and Final Mitigation Plan with the application.

capacity needs of the development in order to relocate the powerlines and utility switchgear adjacent to Johns Creek.
Vehicular access to Southport West would be provided by Park Ave N, Lake Washington Blvd N, and the addition of an
internal center road and frontage road.
The site is generally level and consists of gravel yard and asphalt, a Puget Sound Energy switchgear, and an
office/warehouse building. The site contains high seismic hazard areas and the northeast corner of the site contains
Johns Creek and regulated slopes. The soil consists of a loose to medium dense sand, underlain by soft to medium dense
silt, then medium dense to dense sand, very soft silt and clay, and finally dense to very dense silty sand. Groundwater
was observed in the historical exploration at Southport at depths ranging from 3 to 10 feet below existing grade.
Preliminary estimates of cut and fill include approximately 25,000 cubic yards of excavation and 39,200 cubic yards of fill
from an approved source. The depth of excavation is anticipated to not exceed approximately two feet (2’) below ground
level, except for building cores where excavation would be deeper. Stormwater runoff from pollution generating surfaces
would be captured by catch basins and treated in cartridge filter facilities prior to connection into three (3) existing
drainage systems. No significant trees are proposed to be removed. Southport is proposing to plant 115 new trees along
with a variety of shrubs and perennials. The applicant has submitted a Preliminary Geotechnical Report, Technical
Information Report, Traffic Impact Analysis, and Stream Assessment and Final Mitigation Plan with the application.

PROJECT DESCRIPTION: The applicant, Southport West LLC, is requesting Master Plan Review, Hearing Examiner
Site Plan Review and Environmental (SEPA) Review for the construction of Southport West. Southport West is the
completion of the southerly portion of the Southport Development located at the south end of Lake Washington Blvd N.
The proposed expansion of Southport would be located on the 10.09-acre former Puget Sound Energy (PSE) Substation
and PSE utility parcels (APNs 082305-9191 and -9178). The two (2) parcels are located in the Urban Center-2 (UC-2) zone
and the Urban Design District ‘C’. The site is proposed to be developed as five (5) high-rise buildings with approximately
1,200,000 square feet of office and 50,000 of retail development in multiple phases. The proposed first three phases
would be developed as follows: Phase I – Towers 1 and 2 with the garage podium (July 2023 – July 2027), Phase II –
Towers 3 and 4 with garage podium (July 2027 – July 2031), and Phase III – Tower 5 (post July 2031). Phases 1-3 would
start on the south side of the site (closer to Boeing) and would develop to the north side of the lot (closer to Gene Coulon
Memorial Beach Park). A fourth and final phase is being considered for a sixth tower with 130,000 square feet for office
and retail at the south corner of the development near the intersection of Park Ave N and 757th Ave NE. The phased
development could reach as high as 1.6 million gross square feet. The proposed nine-level development would be built
at the same height and scale as the existing Southport offices with an overall height of approximately 154 feet above
average grade. Parking for 2,207 vehicles would be provided in a shared 4- and 5-level parking garage and 57 spaces are
proposed as on-street parking. In addition, the applicant is proposing to work closely with PSE for the engineering and

PROJECT DESCRIPTION: The applicant, Southport West LLC, is requesting Master Plan Review, Hearing Examiner
Site Plan Review and Environmental (SEPA) Review for the construction of Southport West. Southport West is the
completion of the southerly portion of the Southport Development located at the south end of Lake Washington Blvd N.
The proposed expansion of Southport would be located on the 10.09-acre former Puget Sound Energy (PSE) Substation
and PSE utility parcels (APNs 082305-9191 and -9178). The two (2) parcels are located in the Urban Center-2 (UC-2) zone
and the Urban Design District ‘C’. The site is proposed to be developed as five (5) high-rise buildings with approximately
1,200,000 square feet of office and 50,000 of retail development in multiple phases. The proposed first three phases
would be developed as follows: Phase I – Towers 1 and 2 with the garage podium (July 2023 – July 2027), Phase II –
Towers 3 and 4 with garage podium (July 2027 – July 2031), and Phase III – Tower 5 (post July 2031). Phases 1-3 would
start on the south side of the site (closer to Boeing) and would develop to the north side of the lot (closer to Gene Coulon
Memorial Beach Park). A fourth and final phase is being considered for a sixth tower with 130,000 square feet for office
and retail at the south corner of the development near the intersection of Park Ave N and 757th Ave NE. The phased
development could reach as high as 1.6 million gross square feet. The proposed nine-level development would be built
at the same height and scale as the existing Southport offices with an overall height of approximately 154 feet above
average grade. Parking for 2,207 vehicles would be provided in a shared 4- and 5-level parking garage and 57 spaces are
proposed as on-street parking. In addition, the applicant is proposing to work closely with PSE for the engineering and

capacity needs of the development in order to relocate the powerlines and utility switchgear adjacent to Johns Creek.
Vehicular access to Southport West would be provided by Park Ave N, Lake Washington Blvd N, and the addition of an
internal center road and frontage road.
The site is generally level and consists of gravel yard and asphalt, a Puget Sound Energy switchgear, and an
office/warehouse building. The site contains high seismic hazard areas and the northeast corner of the site contains
Johns Creek and regulated slopes. The soil consists of a loose to medium dense sand, underlain by soft to medium dense
silt, then medium dense to dense sand, very soft silt and clay, and finally dense to very dense silty sand. Groundwater
was observed in the historical exploration at Southport at depths ranging from 3 to 10 feet below existing grade.
Preliminary estimates of cut and fill include approximately 25,000 cubic yards of excavation and 39,200 cubic yards of fill
from an approved source. The depth of excavation is anticipated to not exceed approximately two feet (2’) below ground
level, except for building cores where excavation would be deeper. Stormwater runoff from pollution generating surfaces
would be captured by catch basins and treated in cartridge filter facilities prior to connection into three (3) existing
drainage systems. No significant trees are proposed to be removed. Southport is proposing to plant 115 new trees along
with a variety of shrubs and perennials. The applicant has submitted a Preliminary Geotechnical Report, Technical
Information Report, Traffic Impact Analysis, and Stream Assessment and Final Mitigation Plan with the application.

Vehicular access to Southport West would be provided by Park Ave N, Lake Washington Blvd N, and the addition of an
internal center road and frontage road.
The site is generally level and consists of gravel yard and asphalt, a Puget Sound Energy switchgear, and an
office/warehouse building. The site contains high seismic hazard areas and the northeast corner of the site contains
Johns Creek and regulated slopes. The soil consists of a loose to medium dense sand, underlain by soft to medium dense
silt, then medium dense to dense sand, very soft silt and clay, and finally dense to very dense silty sand. Groundwater
was observed in the historical exploration at Southport at depths ranging from 3 to 10 feet below existing grade.
Preliminary estimates of cut and fill include approximately 25,000 cubic yards of excavation and 39,200 cubic yards of fill
from an approved source. The depth of excavation is anticipated to not exceed approximately two feet (2’) below ground
level, except for building cores where excavation would be deeper. Stormwater runoff from pollution generating surfaces
would be captured by catch basins and treated in cartridge filter facilities prior to connection into three (3) existing
drainage systems. No significant trees are proposed to be removed. Southport is proposing to plant 115 new trees along
with a variety of shrubs and perennials. The applicant has submitted a Preliminary Geotechnical Report, Technical
Information Report, Traffic Impact Analysis, and Stream Assessment and Final Mitigation Plan with the application.

PROJECT DESCRIPTION: The applicant, Southport West LLC, is requesting Master Plan Review, Hearing Examiner
Site Plan Review and Environmental (SEPA) Review for the construction of Southport West. Southport West is the
completion of the southerly portion of the Southport Development located at the south end of Lake Washington Blvd N.
The proposed expansion of Southport would be located on the 10.09-acre former Puget Sound Energy (PSE) Substation
and PSE utility parcels (APNs 082305-9191 and -9178). The two (2) parcels are located in the Urban Center-2 (UC-2) zone
and the Urban Design District ‘C’. The site is proposed to be developed as five (5) high-rise buildings with approximately
1,200,000 square feet of office and 50,000 of retail development in multiple phases. The proposed first three phases
would be developed as follows: Phase I – Towers 1 and 2 with the garage podium (July 2023 – July 2027), Phase II –
Towers 3 and 4 with garage podium (July 2027 – July 2031), and Phase III – Tower 5 (post July 2031). Phases 1-3 would
start on the south side of the site (closer to Boeing) and would develop to the north side of the lot (closer to Gene Coulon
Memorial Beach Park). A fourth and final phase is being considered for a sixth tower with 130,000 square feet for office
and retail at the south corner of the development near the intersection of Park Ave N and 757th Ave NE. The phased
development could reach as high as 1.6 million gross square feet. The proposed nine-level development would be built
at the same height and scale as the existing Southport offices with an overall height of approximately 154 feet above
average grade. Parking for 2,207 vehicles would be provided in a shared 4- and 5-level parking garage and 57 spaces are
proposed as on-street parking. In addition, the applicant is proposing to work closely with PSE for the engineering and

capacity needs of the development in order to relocate the powerlines and utility switchgear adjacent to Johns Creek.
Vehicular access to Southport West would be provided by Park Ave N, Lake Washington Blvd N, and the addition of an
internal center road and frontage road.
The site is generally level and consists of gravel yard and asphalt, a Puget Sound Energy switchgear, and an
office/warehouse building. The site contains high seismic hazard areas and the northeast corner of the site contains
Johns Creek and regulated slopes. The soil consists of a loose to medium dense sand, underlain by soft to medium dense
silt, then medium dense to dense sand, very soft silt and clay, and finally dense to very dense silty sand. Groundwater
was observed in the historical exploration at Southport at depths ranging from 3 to 10 feet below existing grade.
Preliminary estimates of cut and fill include approximately 25,000 cubic yards of excavation and 39,200 cubic yards of fill
from an approved source. The depth of excavation is anticipated to not exceed approximately two feet (2’) below ground
level, except for building cores where excavation would be deeper. Stormwater runoff from pollution generating surfaces
would be captured by catch basins and treated in cartridge filter facilities prior to connection into three (3) existing
drainage systems. No significant trees are proposed to be removed. Southport is proposing to plant 115 new trees along
with a variety of shrubs and perennials. The applicant has submitted a Preliminary Geotechnical Report, Technical
Information Report, Traffic Impact Analysis, and Stream Assessment and Final Mitigation Plan with the application.

PROJECT DESCRIPTION: The applicant, Southport West LLC, is requesting Master Plan Review, Hearing Examiner
Site Plan Review and Environmental (SEPA) Review for the construction of Southport West. Southport West is the
completion of the southerly portion of the Southport Development located at the south end of Lake Washington Blvd N.
The proposed expansion of Southport would be located on the 10.09-acre former Puget Sound Energy (PSE) Substation
and PSE utility parcels (APNs 082305-9191 and -9178). The two (2) parcels are located in the Urban Center-2 (UC-2) zone
and the Urban Design District ‘C’. The site is proposed to be developed as five (5) high-rise buildings with approximately
1,200,000 square feet of office and 50,000 of retail development in multiple phases. The proposed first three phases
would be developed as follows: Phase I – Towers 1 and 2 with the garage podium (July 2023 – July 2027), Phase II –
Towers 3 and 4 with garage podium (July 2027 – July 2031), and Phase III – Tower 5 (post July 2031). Phases 1-3 would
start on the south side of the site (closer to Boeing) and would develop to the north side of the lot (closer to Gene Coulon
Memorial Beach Park). A fourth and final phase is being considered for a sixth tower with 130,000 square feet for office
and retail at the south corner of the development near the intersection of Park Ave N and 757th Ave NE. The phased
development could reach as high as 1.6 million gross square feet. The proposed nine-level development would be built
at the same height and scale as the existing Southport offices with an overall height of approximately 154 feet above
average grade. Parking for 2,207 vehicles would be provided in a shared 4- and 5-level parking garage and 57 spaces are
proposed as on-street parking. In addition, the applicant is proposing to work closely with PSE for the engineering and

capacity needs of the development in order to relocate the powerlines and utility switchgear adjacent to Johns Creek.
Vehicular access to Southport West would be provided by Park Ave N, Lake Washington Blvd N, and the addition of an
internal center road and frontage road.
The site is generally level and consists of gravel yard and asphalt, a Puget Sound Energy switchgear, and an
office/warehouse building. The site contains high seismic hazard areas and the northeast corner of the site contains
Johns Creek and regulated slopes. The soil consists of a loose to medium dense sand, underlain by soft to medium dense
silt, then medium dense to dense sand, very soft silt and clay, and finally dense to very dense silty sand. Groundwater
was observed in the historical exploration at Southport at depths ranging from 3 to 10 feet below existing grade.
Preliminary estimates of cut and fill include approximately 25,000 cubic yards of excavation and 39,200 cubic yards of fill
from an approved source. The depth of excavation is anticipated to not exceed approximately two feet (2’) below ground
level, except for building cores where excavation would be deeper. Stormwater runoff from pollution generating surfaces
would be captured by catch basins and treated in cartridge filter facilities prior to connection into three (3) existing
drainage systems. No significant trees are proposed to be removed. Southport is proposing to plant 115 new trees along
with a variety of shrubs and perennials. The applicant has submitted a Preliminary Geotechnical Report, Technical
Information Report, Traffic Impact Analysis, and Stream Assessment and Final Mitigation Plan with the application.

office/warehouse building. The site contains high seismic hazard areas and the northeast corner of the site contains
Johns Creek and regulated slopes. The soil consists of a loose to medium dense sand, underlain by soft to medium dense
silt, then medium dense to dense sand, very soft silt and clay, and finally dense to very dense silty sand. Groundwater
was observed in the historical exploration at Southport at depths ranging from 3 to 10 feet below existing grade.
Preliminary estimates of cut and fill include approximately 25,000 cubic yards of excavation and 39,200 cubic yards of fill
from an approved source. The depth of excavation is anticipated to not exceed approximately two feet (2’) below ground
level, except for building cores where excavation would be deeper. Stormwater runoff from pollution generating surfaces
would be captured by catch basins and treated in cartridge filter facilities prior to connection into three (3) existing
drainage systems. No significant trees are proposed to be removed. Southport is proposing to plant 115 new trees along
with a variety of shrubs and perennials. The applicant has submitted a Preliminary Geotechnical Report, Technical
Information Report, Traffic Impact Analysis, and Stream Assessment and Final Mitigation Plan with the application.

Site Plan Review and Environmental (SEPA) Review for the construction of Southport West. Southport West is the
completion of the southerly portion of the Southport Development located at the south end of Lake Washington Blvd N.
The proposed expansion of Southport would be located on the 10.09-acre former Puget Sound Energy (PSE) Substation
and PSE utility parcels (APNs 082305-9191 and -9178). The two (2) parcels are located in the Urban Center-2 (UC-2) zone
and the Urban Design District ‘C’. The site is proposed to be developed as five (5) high-rise buildings with approximately
1,200,000 square feet of office and 50,000 of retail development in multiple phases. The proposed first three phases
would be developed as follows: Phase I – Towers 1 and 2 with the garage podium (July 2023 – July 2027), Phase II –
Towers 3 and 4 with garage podium (July 2027 – July 2031), and Phase III – Tower 5 (post July 2031). Phases 1-3 would
start on the south side of the site (closer to Boeing) and would develop to the north side of the lot (closer to Gene Coulon
Memorial Beach Park). A fourth and final phase is being considered for a sixth tower with 130,000 square feet for office
and retail at the south corner of the development near the intersection of Park Ave N and 757th Ave NE. The phased
development could reach as high as 1.6 million gross square feet. The proposed nine-level development would be built
at the same height and scale as the existing Southport offices with an overall height of approximately 154 feet above
average grade. Parking for 2,207 vehicles would be provided in a shared 4- and 5-level parking garage and 57 spaces are
proposed as on-street parking. In addition, the applicant is proposing to work closely with PSE for the engineering and

PROJECT DESCRIPTION: The applicant, Southport West LLC, is requesting Master Plan Review, Hearing Examiner
Site Plan Review and Environmental (SEPA) Review for the construction of Southport West. Southport West is the
completion of the southerly portion of the Southport Development located at the south end of Lake Washington Blvd N.
The proposed expansion of Southport would be located on the 10.09-acre former Puget Sound Energy (PSE) Substation
and PSE utility parcels (APNs 082305-9191 and -9178). The two (2) parcels are located in the Urban Center-2 (UC-2) zone
and the Urban Design District ‘C’. The site is proposed to be developed as five (5) high-rise buildings with approximately
1,200,000 square feet of office and 50,000 of retail development in multiple phases. The proposed first three phases
would be developed as follows: Phase I – Towers 1 and 2 with the garage podium (July 2023 – July 2027), Phase II –
Towers 3 and 4 with garage podium (July 2027 – July 2031), and Phase III – Tower 5 (post July 2031). Phases 1-3 would
start on the south side of the site (closer to Boeing) and would develop to the north side of the lot (closer to Gene Coulon
Memorial Beach Park). A fourth and final phase is being considered for a sixth tower with 130,000 square feet for office
and retail at the south corner of the development near the intersection of Park Ave N and 757th Ave NE. The phased
development could reach as high as 1.6 million gross square feet. The proposed nine-level development would be built
at the same height and scale as the existing Southport offices with an overall height of approximately 154 feet above
average grade. Parking for 2,207 vehicles would be provided in a shared 4- and 5-level parking garage and 57 spaces are
proposed as on-street parking. In addition, the applicant is proposing to work closely with PSE for the engineering and

capacity needs of the development in order to relocate the powerlines and utility switchgear adjacent to Johns Creek.
Vehicular access to Southport West would be provided by Park Ave N, Lake Washington Blvd N, and the addition of an
internal center road and frontage road.
The site is generally level and consists of gravel yard and asphalt, a Puget Sound Energy switchgear, and an
office/warehouse building. The site contains high seismic hazard areas and the northeast corner of the site contains
Johns Creek and regulated slopes. The soil consists of a loose to medium dense sand, underlain by soft to medium dense
silt, then medium dense to dense sand, very soft silt and clay, and finally dense to very dense silty sand. Groundwater
was observed in the historical exploration at Southport at depths ranging from 3 to 10 feet below existing grade.
Preliminary estimates of cut and fill include approximately 25,000 cubic yards of excavation and 39,200 cubic yards of fill
from an approved source. The depth of excavation is anticipated to not exceed approximately two feet (2’) below ground
level, except for building cores where excavation would be deeper. Stormwater runoff from pollution generating surfaces
would be captured by catch basins and treated in cartridge filter facilities prior to connection into three (3) existing
drainage systems. No significant trees are proposed to be removed. Southport is proposing to plant 115 new trees along
with a variety of shrubs and perennials. The applicant has submitted a Preliminary Geotechnical Report, Technical
Information Report, Traffic Impact Analysis, and Stream Assessment and Final Mitigation Plan with the application.

capacity needs of the development in order to relocate the powerlines and utility switchgear adjacent to Johns Creek.
Vehicular access to Southport West would be provided by Park Ave N, Lake Washington Blvd N, and the addition of an
internal center road and frontage road.
The site is generally level and consists of gravel yard and asphalt, a Puget Sound Energy switchgear, and an
office/warehouse building. The site contains high seismic hazard areas and the northeast corner of the site contains
Johns Creek and regulated slopes. The soil consists of a loose to medium dense sand, underlain by soft to medium dense
silt, then medium dense to dense sand, very soft silt and clay, and finally dense to very dense silty sand. Groundwater
was observed in the historical exploration at Southport at depths ranging from 3 to 10 feet below existing grade.
Preliminary estimates of cut and fill include approximately 25,000 cubic yards of excavation and 39,200 cubic yards of fill
from an approved source. The depth of excavation is anticipated to not exceed approximately two feet (2’) below ground
level, except for building cores where excavation would be deeper. Stormwater runoff from pollution generating surfaces
would be captured by catch basins and treated in cartridge filter facilities prior to connection into three (3) existing
drainage systems. No significant trees are proposed to be removed. Southport is proposing to plant 115 new trees along
with a variety of shrubs and perennials. The applicant has submitted a Preliminary Geotechnical Report, Technical
Information Report, Traffic Impact Analysis, and Stream Assessment and Final Mitigation Plan with the application.

The proposed expansion of Southport would be located on the 10.09-acre former Puget Sound Energy (PSE) Substation
and PSE utility parcels (APNs 082305-9191 and -9178). The two (2) parcels are located in the Urban Center-2 (UC-2) zone
and the Urban Design District ‘C’. The site is proposed to be developed as five (5) high-rise buildings with approximately
1,200,000 square feet of office and 50,000 of retail development in multiple phases. The proposed first three phases
would be developed as follows: Phase I – Towers 1 and 2 with the garage podium (July 2023 – July 2027), Phase II –
Towers 3 and 4 with garage podium (July 2027 – July 2031), and Phase III – Tower 5 (post July 2031). Phases 1-3 would
start on the south side of the site (closer to Boeing) and would develop to the north side of the lot (closer to Gene Coulon
Memorial Beach Park). A fourth and final phase is being considered for a sixth tower with 130,000 square feet for office
and retail at the south corner of the development near the intersection of Park Ave N and 757th Ave NE. The phased
development could reach as high as 1.6 million gross square feet. The proposed nine-level development would be built
at the same height and scale as the existing Southport offices with an overall height of approximately 154 feet above
average grade. Parking for 2,207 vehicles would be provided in a shared 4- and 5-level parking garage and 57 spaces are

PROJECT DESCRIPTION: The applicant, Southport West LLC, is requesting Master Plan Review, Hearing Examiner
Site Plan Review and Environmental (SEPA) Review for the construction of Southport West. Southport West is the
completion of the southerly portion of the Southport Development located at the south end of Lake Washington Blvd N.
The proposed expansion of Southport would be located on the 10.09-acre former Puget Sound Energy (PSE) Substation
and PSE utility parcels (APNs 082305-9191 and -9178). The two (2) parcels are located in the Urban Center-2 (UC-2) zone
and the Urban Design District ‘C’. The site is proposed to be developed as five (5) high-rise buildings with approximately
1,200,000 square feet of office and 50,000 of retail development in multiple phases. The proposed first three phases
would be developed as follows: Phase I – Towers 1 and 2 with the garage podium (July 2023 – July 2027), Phase II –
Towers 3 and 4 with garage podium (July 2027 – July 2031), and Phase III – Tower 5 (post July 2031). Phases 1-3 would
start on the south side of the site (closer to Boeing) and would develop to the north side of the lot (closer to Gene Coulon
Memorial Beach Park). A fourth and final phase is being considered for a sixth tower with 130,000 square feet for office
and retail at the south corner of the development near the intersection of Park Ave N and 757th Ave NE. The phased
development could reach as high as 1.6 million gross square feet. The proposed nine-level development would be built
at the same height and scale as the existing Southport offices with an overall height of approximately 154 feet above
average grade. Parking for 2,207 vehicles would be provided in a shared 4- and 5-level parking garage and 57 spaces are
proposed as on-street parking. In addition, the applicant is proposing to work closely with PSE for the engineering and

capacity needs of the development in order to relocate the powerlines and utility switchgear adjacent to Johns Creek.
Vehicular access to Southport West would be provided by Park Ave N, Lake Washington Blvd N, and the addition of an
internal center road and frontage road.
The site is generally level and consists of gravel yard and asphalt, a Puget Sound Energy switchgear, and an
office/warehouse building. The site contains high seismic hazard areas and the northeast corner of the site contains
Johns Creek and regulated slopes. The soil consists of a loose to medium dense sand, underlain by soft to medium dense
silt, then medium dense to dense sand, very soft silt and clay, and finally dense to very dense silty sand. Groundwater
was observed in the historical exploration at Southport at depths ranging from 3 to 10 feet below existing grade.
Preliminary estimates of cut and fill include approximately 25,000 cubic yards of excavation and 39,200 cubic yards of fill
from an approved source. The depth of excavation is anticipated to not exceed approximately two feet (2’) below ground
level, except for building cores where excavation would be deeper. Stormwater runoff from pollution generating surfaces
would be captured by catch basins and treated in cartridge filter facilities prior to connection into three (3) existing
drainage systems. No significant trees are proposed to be removed. Southport is proposing to plant 115 new trees along
with a variety of shrubs and perennials. The applicant has submitted a Preliminary Geotechnical Report, Technical
Information Report, Traffic Impact Analysis, and Stream Assessment and Final Mitigation Plan with the application.

and PSE utility parcels (APNs 082305-9191 and -9178). The two (2) parcels are located in the Urban Center-2 (UC-2) zone
and the Urban Design District ‘C’. The site is proposed to be developed as five (5) high-rise buildings with approximately
1,200,000 square feet of office and 50,000 of retail development in multiple phases. The proposed first three phases
would be developed as follows: Phase I – Towers 1 and 2 with the garage podium (July 2023 – July 2027), Phase II –
Towers 3 and 4 with garage podium (July 2027 – July 2031), and Phase III – Tower 5 (post July 2031). Phases 1-3 would
start on the south side of the site (closer to Boeing) and would develop to the north side of the lot (closer to Gene Coulon
Memorial Beach Park). A fourth and final phase is being considered for a sixth tower with 130,000 square feet for office
and retail at the south corner of the development near the intersection of Park Ave N and 757th Ave NE. The phased
development could reach as high as 1.6 million gross square feet. The proposed nine-level development would be built
at the same height and scale as the existing Southport offices with an overall height of approximately 154 feet above
average grade. Parking for 2,207 vehicles would be provided in a shared 4- and 5-level parking garage and 57 spaces are
proposed as on-street parking. In addition, the applicant is proposing to work closely with PSE for the engineering and

capacity needs of the development in order to relocate the powerlines and utility switchgear adjacent to Johns Creek.
Vehicular access to Southport West would be provided by Park Ave N, Lake Washington Blvd N, and the addition of an
internal center road and frontage road.
The site is generally level and consists of gravel yard and asphalt, a Puget Sound Energy switchgear, and an
office/warehouse building. The site contains high seismic hazard areas and the northeast corner of the site contains
Johns Creek and regulated slopes. The soil consists of a loose to medium dense sand, underlain by soft to medium dense
silt, then medium dense to dense sand, very soft silt and clay, and finally dense to very dense silty sand. Groundwater
was observed in the historical exploration at Southport at depths ranging from 3 to 10 feet below existing grade.
Preliminary estimates of cut and fill include approximately 25,000 cubic yards of excavation and 39,200 cubic yards of fill
from an approved source. The depth of excavation is anticipated to not exceed approximately two feet (2’) below ground
level, except for building cores where excavation would be deeper. Stormwater runoff from pollution generating surfaces
would be captured by catch basins and treated in cartridge filter facilities prior to connection into three (3) existing
drainage systems. No significant trees are proposed to be removed. Southport is proposing to plant 115 new trees along
with a variety of shrubs and perennials. The applicant has submitted a Preliminary Geotechnical Report, Technical
Information Report, Traffic Impact Analysis, and Stream Assessment and Final Mitigation Plan with the application.

PROJECT DESCRIPTION: The applicant, Southport West LLC, is requesting Master Plan Review, Hearing Examiner
Site Plan Review and Environmental (SEPA) Review for the construction of Southport West. Southport West is the
completion of the southerly portion of the Southport Development located at the south end of Lake Washington Blvd N.
The proposed expansion of Southport would be located on the 10.09-acre former Puget Sound Energy (PSE) Substation
and PSE utility parcels (APNs 082305-9191 and -9178). The two (2) parcels are located in the Urban Center-2 (UC-2) zone
and the Urban Design District ‘C’. The site is proposed to be developed as five (5) high-rise buildings with approximately
1,200,000 square feet of office and 50,000 of retail development in multiple phases. The proposed first three phases
would be developed as follows: Phase I – Towers 1 and 2 with the garage podium (July 2023 – July 2027), Phase II –
Towers 3 and 4 with garage podium (July 2027 – July 2031), and Phase III – Tower 5 (post July 2031). Phases 1-3 would
start on the south side of the site (closer to Boeing) and would develop to the north side of the lot (closer to Gene Coulon
Memorial Beach Park). A fourth and final phase is being considered for a sixth tower with 130,000 square feet for office
and retail at the south corner of the development near the intersection of Park Ave N and 757th Ave NE. The phased
development could reach as high as 1.6 million gross square feet. The proposed nine-level development would be built
at the same height and scale as the existing Southport offices with an overall height of approximately 154 feet above
average grade. Parking for 2,207 vehicles would be provided in a shared 4- and 5-level parking garage and 57 spaces are
proposed as on-street parking. In addition, the applicant is proposing to work closely with PSE for the engineering and

Vehicular access to Southport West would be provided by Park Ave N, Lake Washington Blvd N, and the addition of an
internal center road and frontage road.
The site is generally level and consists of gravel yard and asphalt, a Puget Sound Energy switchgear, and an
office/warehouse building. The site contains high seismic hazard areas and the northeast corner of the site contains
Johns Creek and regulated slopes. The soil consists of a loose to medium dense sand, underlain by soft to medium dense
silt, then medium dense to dense sand, very soft silt and clay, and finally dense to very dense silty sand. Groundwater
was observed in the historical exploration at Southport at depths ranging from 3 to 10 feet below existing grade.
Preliminary estimates of cut and fill include approximately 25,000 cubic yards of excavation and 39,200 cubic yards of fill
from an approved source. The depth of excavation is anticipated to not exceed approximately two feet (2’) below ground
level, except for building cores where excavation would be deeper. Stormwater runoff from pollution generating surfaces
would be captured by catch basins and treated in cartridge filter facilities prior to connection into three (3) existing
drainage systems. No significant trees are proposed to be removed. Southport is proposing to plant 115 new trees along
with a variety of shrubs and perennials. The applicant has submitted a Preliminary Geotechnical Report, Technical
Information Report, Traffic Impact Analysis, and Stream Assessment and Final Mitigation Plan with the application.

PROJECT DESCRIPTION: The applicant, Southport West LLC, is requesting Master Plan Review, Hearing Examiner
Site Plan Review and Environmental (SEPA) Review for the construction of Southport West. Southport West is the
completion of the southerly portion of the Southport Development located at the south end of Lake Washington Blvd N.
The proposed expansion of Southport would be located on the 10.09-acre former Puget Sound Energy (PSE) Substation
and PSE utility parcels (APNs 082305-9191 and -9178). The two (2) parcels are located in the Urban Center-2 (UC-2) zone
and the Urban Design District ‘C’. The site is proposed to be developed as five (5) high-rise buildings with approximately
1,200,000 square feet of office and 50,000 of retail development in multiple phases. The proposed first three phases
would be developed as follows: Phase I – Towers 1 and 2 with the garage podium (July 2023 – July 2027), Phase II –
Towers 3 and 4 with garage podium (July 2027 – July 2031), and Phase III – Tower 5 (post July 2031). Phases 1-3 would
start on the south side of the site (closer to Boeing) and would develop to the north side of the lot (closer to Gene Coulon
Memorial Beach Park). A fourth and final phase is being considered for a sixth tower with 130,000 square feet for office
and retail at the south corner of the development near the intersection of Park Ave N and 757th Ave NE. The phased
development could reach as high as 1.6 million gross square feet. The proposed nine-level development would be built
at the same height and scale as the existing Southport offices with an overall height of approximately 154 feet above
average grade. Parking for 2,207 vehicles would be provided in a shared 4- and 5-level parking garage and 57 spaces are
proposed as on-street parking. In addition, the applicant is proposing to work closely with PSE for the engineering and

capacity needs of the development in order to relocate the powerlines and utility switchgear adjacent to Johns Creek.
Vehicular access to Southport West would be provided by Park Ave N, Lake Washington Blvd N, and the addition of an
internal center road and frontage road.
The site is generally level and consists of gravel yard and asphalt, a Puget Sound Energy switchgear, and an
office/warehouse building. The site contains high seismic hazard areas and the northeast corner of the site contains
Johns Creek and regulated slopes. The soil consists of a loose to medium dense sand, underlain by soft to medium dense
silt, then medium dense to dense sand, very soft silt and clay, and finally dense to very dense silty sand. Groundwater
was observed in the historical exploration at Southport at depths ranging from 3 to 10 feet below existing grade.
Preliminary estimates of cut and fill include approximately 25,000 cubic yards of excavation and 39,200 cubic yards of fill
from an approved source. The depth of excavation is anticipated to not exceed approximately two feet (2’) below ground
level, except for building cores where excavation would be deeper. Stormwater runoff from pollution generating surfaces
would be captured by catch basins and treated in cartridge filter facilities prior to connection into three (3) existing
drainage systems. No significant trees are proposed to be removed. Southport is proposing to plant 115 new trees along
with a variety of shrubs and perennials. The applicant has submitted a Preliminary Geotechnical Report, Technical
Information Report, Traffic Impact Analysis, and Stream Assessment and Final Mitigation Plan with the application.

capacity needs of the development in order to relocate the powerlines and utility switchgear adjacent to Johns Creek.
Vehicular access to Southport West would be provided by Park Ave N, Lake Washington Blvd N, and the addition of an
internal center road and frontage road.
The site is generally level and consists of gravel yard and asphalt, a Puget Sound Energy switchgear, and an
office/warehouse building. The site contains high seismic hazard areas and the northeast corner of the site contains
Johns Creek and regulated slopes. The soil consists of a loose to medium dense sand, underlain by soft to medium dense
silt, then medium dense to dense sand, very soft silt and clay, and finally dense to very dense silty sand. Groundwater
was observed in the historical exploration at Southport at depths ranging from 3 to 10 feet below existing grade.
Preliminary estimates of cut and fill include approximately 25,000 cubic yards of excavation and 39,200 cubic yards of fill
from an approved source. The depth of excavation is anticipated to not exceed approximately two feet (2’) below ground
level, except for building cores where excavation would be deeper. Stormwater runoff from pollution generating surfaces
would be captured by catch basins and treated in cartridge filter facilities prior to connection into three (3) existing
drainage systems. No significant trees are proposed to be removed. Southport is proposing to plant 115 new trees along
with a variety of shrubs and perennials. The applicant has submitted a Preliminary Geotechnical Report, Technical
Information Report, Traffic Impact Analysis, and Stream Assessment and Final Mitigation Plan with the application.

Site Plan Review and Environmental (SEPA) Review for the construction of Southport West. Southport West is the
completion of the southerly portion of the Southport Development located at the south end of Lake Washington Blvd N.
The proposed expansion of Southport would be located on the 10.09-acre former Puget Sound Energy (PSE) Substation
and PSE utility parcels (APNs 082305-9191 and -9178). The two (2) parcels are located in the Urban Center-2 (UC-2) zone
and the Urban Design District ‘C’. The site is proposed to be developed as five (5) high-rise buildings with approximately
1,200,000 square feet of office and 50,000 of retail development in multiple phases. The proposed first three phases
would be developed as follows: Phase I – Towers 1 and 2 with the garage podium (July 2023 – July 2027), Phase II –
Towers 3 and 4 with garage podium (July 2027 – July 2031), and Phase III – Tower 5 (post July 2031). Phases 1-3 would
start on the south side of the site (closer to Boeing) and would develop to the north side of the lot (closer to Gene Coulon
Memorial Beach Park). A fourth and final phase is being considered for a sixth tower with 130,000 square feet for office
and retail at the south corner of the development near the intersection of Park Ave N and 757th Ave NE. The phased
development could reach as high as 1.6 million gross square feet. The proposed nine-level development would be built
at the same height and scale as the existing Southport offices with an overall height of approximately 154 feet above
average grade. Parking for 2,207 vehicles would be provided in a shared 4- and 5-level parking garage and 57 spaces are
proposed as on-street parking. In addition, the applicant is proposing to work closely with PSE for the engineering and

PROJECT DESCRIPTION: The applicant, Southport West LLC, is requesting Master Plan Review, Hearing Examiner
Site Plan Review and Environmental (SEPA) Review for the construction of Southport West. Southport West is the
completion of the southerly portion of the Southport Development located at the south end of Lake Washington Blvd N.
The proposed expansion of Southport would be located on the 10.09-acre former Puget Sound Energy (PSE) Substation
and PSE utility parcels (APNs 082305-9191 and -9178). The two (2) parcels are located in the Urban Center-2 (UC-2) zone
and the Urban Design District ‘C’. The site is proposed to be developed as five (5) high-rise buildings with approximately
1,200,000 square feet of office and 50,000 of retail development in multiple phases. The proposed first three phases
would be developed as follows: Phase I – Towers 1 and 2 with the garage podium (July 2023 – July 2027), Phase II –
Towers 3 and 4 with garage podium (July 2027 – July 2031), and Phase III – Tower 5 (post July 2031). Phases 1-3 would
start on the south side of the site (closer to Boeing) and would develop to the north side of the lot (closer to Gene Coulon
Memorial Beach Park). A fourth and final phase is being considered for a sixth tower with 130,000 square feet for office
and retail at the south corner of the development near the intersection of Park Ave N and 757th Ave NE. The phased
development could reach as high as 1.6 million gross square feet. The proposed nine-level development would be built
at the same height and scale as the existing Southport offices with an overall height of approximately 154 feet above
average grade. Parking for 2,207 vehicles would be provided in a shared 4- and 5-level parking garage and 57 spaces are
proposed as on-street parking. In addition, the applicant is proposing to work closely with PSE for the engineering and

capacity needs of the development in order to relocate the powerlines and utility switchgear adjacent to Johns Creek.
Vehicular access to Southport West would be provided by Park Ave N, Lake Washington Blvd N, and the addition of an
internal center road and frontage road.
The site is generally level and consists of gravel yard and asphalt, a Puget Sound Energy switchgear, and an
office/warehouse building. The site contains high seismic hazard areas and the northeast corner of the site contains
Johns Creek and regulated slopes. The soil consists of a loose to medium dense sand, underlain by soft to medium dense
silt, then medium dense to dense sand, very soft silt and clay, and finally dense to very dense silty sand. Groundwater
was observed in the historical exploration at Southport at depths ranging from 3 to 10 feet below existing grade.
Preliminary estimates of cut and fill include approximately 25,000 cubic yards of excavation and 39,200 cubic yards of fill
from an approved source. The depth of excavation is anticipated to not exceed approximately two feet (2’) below ground
level, except for building cores where excavation would be deeper. Stormwater runoff from pollution generating surfaces
would be captured by catch basins and treated in cartridge filter facilities prior to connection into three (3) existing
drainage systems. No significant trees are proposed to be removed. Southport is proposing to plant 115 new trees along
with a variety of shrubs and perennials. The applicant has submitted a Preliminary Geotechnical Report, Technical
Information Report, Traffic Impact Analysis, and Stream Assessment and Final Mitigation Plan with the application.

Vehicular access to Southport West would be provided by Park Ave N, Lake Washington Blvd N, and the addition of an
internal center road and frontage road.
The site is generally level and consists of gravel yard and asphalt, a Puget Sound Energy switchgear, and an
office/warehouse building. The site contains high seismic hazard areas and the northeast corner of the site contains
Johns Creek and regulated slopes. The soil consists of a loose to medium dense sand, underlain by soft to medium dense
silt, then medium dense to dense sand, very soft silt and clay, and finally dense to very dense silty sand. Groundwater
was observed in the historical exploration at Southport at depths ranging from 3 to 10 feet below existing grade.
Preliminary estimates of cut and fill include approximately 25,000 cubic yards of excavation and 39,200 cubic yards of fill
from an approved source. The depth of excavation is anticipated to not exceed approximately two feet (2’) below ground
level, except for building cores where excavation would be deeper. Stormwater runoff from pollution generating surfaces
would be captured by catch basins and treated in cartridge filter facilities prior to connection into three (3) existing
drainage systems. No significant trees are proposed to be removed. Southport is proposing to plant 115 new trees along
with a variety of shrubs and perennials. The applicant has submitted a Preliminary Geotechnical Report, Technical
Information Report, Traffic Impact Analysis, and Stream Assessment and Final Mitigation Plan with the application.

PROJECT DESCRIPTION: The applicant, Southport West LLC, is requesting Master Plan Review, Hearing Examiner
Site Plan Review and Environmental (SEPA) Review for the construction of Southport West. Southport West is the
completion of the southerly portion of the Southport Development located at the south end of Lake Washington Blvd N.
The proposed expansion of Southport would be located on the 10.09-acre former Puget Sound Energy (PSE) Substation
and PSE utility parcels (APNs 082305-9191 and -9178). The two (2) parcels are located in the Urban Center-2 (UC-2) zone
and the Urban Design District ‘C’. The site is proposed to be developed as five (5) high-rise buildings with approximately
1,200,000 square feet of office and 50,000 of retail development in multiple phases. The proposed first three phases
would be developed as follows: Phase I – Towers 1 and 2 with the garage podium (July 2023 – July 2027), Phase II –
Towers 3 and 4 with garage podium (July 2027 – July 2031), and Phase III – Tower 5 (post July 2031). Phases 1-3 would
start on the south side of the site (closer to Boeing) and would develop to the north side of the lot (closer to Gene Coulon
Memorial Beach Park). A fourth and final phase is being considered for a sixth tower with 130,000 square feet for office
and retail at the south corner of the development near the intersection of Park Ave N and 757th Ave NE. The phased
development could reach as high as 1.6 million gross square feet. The proposed nine-level development would be built
at the same height and scale as the existing Southport offices with an overall height of approximately 154 feet above
average grade. Parking for 2,207 vehicles would be provided in a shared 4- and 5-level parking garage and 57 spaces are
proposed as on-street parking. In addition, the applicant is proposing to work closely with PSE for the engineering and

capacity needs of the development in order to relocate the powerlines and utility switchgear adjacent to Johns Creek.
Vehicular access to Southport West would be provided by Park Ave N, Lake Washington Blvd N, and the addition of an
internal center road and frontage road.
The site is generally level and consists of gravel yard and asphalt, a Puget Sound Energy switchgear, and an
office/warehouse building. The site contains high seismic hazard areas and the northeast corner of the site contains
Johns Creek and regulated slopes. The soil consists of a loose to medium dense sand, underlain by soft to medium dense
silt, then medium dense to dense sand, very soft silt and clay, and finally dense to very dense silty sand. Groundwater
was observed in the historical exploration at Southport at depths ranging from 3 to 10 feet below existing grade.
Preliminary estimates of cut and fill include approximately 25,000 cubic yards of excavation and 39,200 cubic yards of fill
from an approved source. The depth of excavation is anticipated to not exceed approximately two feet (2’) below ground
level, except for building cores where excavation would be deeper. Stormwater runoff from pollution generating surfaces
would be captured by catch basins and treated in cartridge filter facilities prior to connection into three (3) existing
drainage systems. No significant trees are proposed to be removed. Southport is proposing to plant 115 new trees along
with a variety of shrubs and perennials. The applicant has submitted a Preliminary Geotechnical Report, Technical
Information Report, Traffic Impact Analysis, and Stream Assessment and Final Mitigation Plan with the application.

PROJECT DESCRIPTION: The applicant, Southport West LLC, is requesting Master Plan Review, Hearing Examiner
Site Plan Review and Environmental (SEPA) Review for the construction of Southport West. Southport West is the
completion of the southerly portion of the Southport Development located at the south end of Lake Washington Blvd N.
The proposed expansion of Southport would be located on the 10.09-acre former Puget Sound Energy (PSE) Substation
and PSE utility parcels (APNs 082305-9191 and -9178). The two (2) parcels are located in the Urban Center-2 (UC-2) zone
and the Urban Design District ‘C’. The site is proposed to be developed as five (5) high-rise buildings with approximately
1,200,000 square feet of office and 50,000 of retail development in multiple phases. The proposed first three phases
would be developed as follows: Phase I – Towers 1 and 2 with the garage podium (July 2023 – July 2027), Phase II –
Towers 3 and 4 with garage podium (July 2027 – July 2031), and Phase III – Tower 5 (post July 2031). Phases 1-3 would
start on the south side of the site (closer to Boeing) and would develop to the north side of the lot (closer to Gene Coulon
Memorial Beach Park). A fourth and final phase is being considered for a sixth tower with 130,000 square feet for office
and retail at the south corner of the development near the intersection of Park Ave N and 757th Ave NE. The phased
development could reach as high as 1.6 million gross square feet. The proposed nine-level development would be built
at the same height and scale as the existing Southport offices with an overall height of approximately 154 feet above
average grade. Parking for 2,207 vehicles would be provided in a shared 4- and 5-level parking garage and 57 spaces are
proposed as on-street parking. In addition, the applicant is proposing to work closely with PSE for the engineering and

capacity needs of the development in order to relocate the powerlines and utility switchgear adjacent to Johns Creek.
Vehicular access to Southport West would be provided by Park Ave N, Lake Washington Blvd N, and the addition of an
internal center road and frontage road.
The site is generally level and consists of gravel yard and asphalt, a Puget Sound Energy switchgear, and an
office/warehouse building. The site contains high seismic hazard areas and the northeast corner of the site contains
Johns Creek and regulated slopes. The soil consists of a loose to medium dense sand, underlain by soft to medium dense
silt, then medium dense to dense sand, very soft silt and clay, and finally dense to very dense silty sand. Groundwater
was observed in the historical exploration at Southport at depths ranging from 3 to 10 feet below existing grade.
Preliminary estimates of cut and fill include approximately 25,000 cubic yards of excavation and 39,200 cubic yards of fill
from an approved source. The depth of excavation is anticipated to not exceed approximately two feet (2’) below ground
level, except for building cores where excavation would be deeper. Stormwater runoff from pollution generating surfaces
would be captured by catch basins and treated in cartridge filter facilities prior to connection into three (3) existing
drainage systems. No significant trees are proposed to be removed. Southport is proposing to plant 115 new trees along
with a variety of shrubs and perennials. The applicant has submitted a Preliminary Geotechnical Report, Technical
Information Report, Traffic Impact Analysis, and Stream Assessment and Final Mitigation Plan with the application.

PROJECT DESCRIPTION: The applicant, Southport West LLC, is requesting Master Plan Review, Hearing Examiner
Site Plan Review and Environmental (SEPA) Review for the construction of Southport West. Southport West is the
completion of the southerly portion of the Southport Development located at the south end of Lake Washington Blvd N.
The proposed expansion of Southport would be located on the 10.09-acre former Puget Sound Energy (PSE) Substation
and PSE utility parcels (APNs 082305-9191 and -9178). The two (2) parcels are located in the Urban Center-2 (UC-2) zone
and the Urban Design District ‘C’. The site is proposed to be developed as five (5) high-rise buildings with approximately
1,200,000 square feet of office and 50,000 of retail development in multiple phases. The proposed first three phases
would be developed as follows: Phase I – Towers 1 and 2 with the garage podium (July 2023 – July 2027), Phase II –
Towers 3 and 4 with garage podium (July 2027 – July 2031), and Phase III – Tower 5 (post July 2031). Phases 1-3 would
start on the south side of the site (closer to Boeing) and would develop to the north side of the lot (closer to Gene Coulon
Memorial Beach Park). A fourth and final phase is being considered for a sixth tower with 130,000 square feet for office
and retail at the south corner of the development near the intersection of Park Ave N and 757th Ave NE. The phased
development could reach as high as 1.6 million gross square feet. The proposed nine-level development would be built
at the same height and scale as the existing Southport offices with an overall height of approximately 154 feet above
average grade. Parking for 2,207 vehicles would be provided in a shared 4- and 5-level parking garage and 57 spaces are
proposed as on-street parking. In addition, the applicant is proposing to work closely with PSE for the engineering and

Vehicular access to Southport West would be provided by Park Ave N, Lake Washington Blvd N, and the addition of an
internal center road and frontage road.
The site is generally level and consists of gravel yard and asphalt, a Puget Sound Energy switchgear, and an
office/warehouse building. The site contains high seismic hazard areas and the northeast corner of the site contains
Johns Creek and regulated slopes. The soil consists of a loose to medium dense sand, underlain by soft to medium dense
silt, then medium dense to dense sand, very soft silt and clay, and finally dense to very dense silty sand. Groundwater
was observed in the historical exploration at Southport at depths ranging from 3 to 10 feet below existing grade.
Preliminary estimates of cut and fill include approximately 25,000 cubic yards of excavation and 39,200 cubic yards of fill
from an approved source. The depth of excavation is anticipated to not exceed approximately two feet (2’) below ground
level, except for building cores where excavation would be deeper. Stormwater runoff from pollution generating surfaces
would be captured by catch basins and treated in cartridge filter facilities prior to connection into three (3) existing

PROJECT DESCRIPTION: The applicant, Southport West LLC, is requesting Master Plan Review, Hearing Examiner
Site Plan Review and Environmental (SEPA) Review for the construction of Southport West. Southport West is the
completion of the southerly portion of the Southport Development located at the south end of Lake Washington Blvd N.
The proposed expansion of Southport would be located on the 10.09-acre former Puget Sound Energy (PSE) Substation
and PSE utility parcels (APNs 082305-9191 and -9178). The two (2) parcels are located in the Urban Center-2 (UC-2) zone
and the Urban Design District ‘C’. The site is proposed to be developed as five (5) high-rise buildings with approximately
1,200,000 square feet of office and 50,000 of retail development in multiple phases. The proposed first three phases
would be developed as follows: Phase I – Towers 1 and 2 with the garage podium (July 2023 – July 2027), Phase II –
Towers 3 and 4 with garage podium (July 2027 – July 2031), and Phase III – Tower 5 (post July 2031). Phases 1-3 would
start on the south side of the site (closer to Boeing) and would develop to the north side of the lot (closer to Gene Coulon
Memorial Beach Park). A fourth and final phase is being considered for a sixth tower with 130,000 square feet for office
and retail at the south corner of the development near the intersection of Park Ave N and 757th Ave NE. The phased
development could reach as high as 1.6 million gross square feet. The proposed nine-level development would be built
at the same height and scale as the existing Southport offices with an overall height of approximately 154 feet above
average grade. Parking for 2,207 vehicles would be provided in a shared 4- and 5-level parking garage and 57 spaces are
proposed as on-street parking. In addition, the applicant is proposing to work closely with PSE for the engineering and

capacity needs of the development in order to relocate the powerlines and utility switchgear adjacent to Johns Creek.
Vehicular access to Southport West would be provided by Park Ave N, Lake Washington Blvd N, and the addition of an
internal center road and frontage road.
The site is generally level and consists of gravel yard and asphalt, a Puget Sound Energy switchgear, and an
office/warehouse building. The site contains high seismic hazard areas and the northeast corner of the site contains
Johns Creek and regulated slopes. The soil consists of a loose to medium dense sand, underlain by soft to medium dense
silt, then medium dense to dense sand, very soft silt and clay, and finally dense to very dense silty sand. Groundwater
was observed in the historical exploration at Southport at depths ranging from 3 to 10 feet below existing grade.
Preliminary estimates of cut and fill include approximately 25,000 cubic yards of excavation and 39,200 cubic yards of fill
from an approved source. The depth of excavation is anticipated to not exceed approximately two feet (2’) below ground
level, except for building cores where excavation would be deeper. Stormwater runoff from pollution generating surfaces
would be captured by catch basins and treated in cartridge filter facilities prior to connection into three (3) existing
drainage systems. No significant trees are proposed to be removed. Southport is proposing to plant 115 new trees along
with a variety of shrubs and perennials. The applicant has submitted a Preliminary Geotechnical Report, Technical
Information Report, Traffic Impact Analysis, and Stream Assessment and Final Mitigation Plan with the application.

capacity needs of the development in order to relocate the powerlines and utility switchgear adjacent to Johns Creek.
Vehicular access to Southport West would be provided by Park Ave N, Lake Washington Blvd N, and the addition of an
internal center road and frontage road.
The site is generally level and consists of gravel yard and asphalt, a Puget Sound Energy switchgear, and an
office/warehouse building. The site contains high seismic hazard areas and the northeast corner of the site contains
Johns Creek and regulated slopes. The soil consists of a loose to medium dense sand, underlain by soft to medium dense
silt, then medium dense to dense sand, very soft silt and clay, and finally dense to very dense silty sand. Groundwater
was observed in the historical exploration at Southport at depths ranging from 3 to 10 feet below existing grade.
Preliminary estimates of cut and fill include approximately 25,000 cubic yards of excavation and 39,200 cubic yards of fill
from an approved source. The depth of excavation is anticipated to not exceed approximately two feet (2’) below ground
level, except for building cores where excavation would be deeper. Stormwater runoff from pollution generating surfaces
would be captured by catch basins and treated in cartridge filter facilities prior to connection into three (3) existing
drainage systems. No significant trees are proposed to be removed. Southport is proposing to plant 115 new trees along
with a variety of shrubs and perennials. The applicant has submitted a Preliminary Geotechnical Report, Technical
Information Report, Traffic Impact Analysis, and Stream Assessment and Final Mitigation Plan with the application.

PROJECT DESCRIPTION: The applicant, Southport West LLC, is requesting Master Plan Review, Hearing Examiner
Site Plan Review and Environmental (SEPA) Review for the construction of Southport West. Southport West is the
completion of the southerly portion of the Southport Development located at the south end of Lake Washington Blvd N.
The proposed expansion of Southport would be located on the 10.09-acre former Puget Sound Energy (PSE) Substation
and PSE utility parcels (APNs 082305-9191 and -9178). The two (2) parcels are located in the Urban Center-2 (UC-2) zone
and the Urban Design District ‘C’. The site is proposed to be developed as five (5) high-rise buildings with approximately
1,200,000 square feet of office and 50,000 of retail development in multiple phases. The proposed first three phases
would be developed as follows: Phase I – Towers 1 and 2 with the garage podium (July 2023 – July 2027), Phase II –
Towers 3 and 4 with garage podium (July 2027 – July 2031), and Phase III – Tower 5 (post July 2031). Phases 1-3 would
start on the south side of the site (closer to Boeing) and would develop to the north side of the lot (closer to Gene Coulon
Memorial Beach Park). A fourth and final phase is being considered for a sixth tower with 130,000 square feet for office
and retail at the south corner of the development near the intersection of Park Ave N and 757th Ave NE. The phased
development could reach as high as 1.6 million gross square feet. The proposed nine-level development would be built
at the same height and scale as the existing Southport offices with an overall height of approximately 154 feet above
average grade. Parking for 2,207 vehicles would be provided in a shared 4- and 5-level parking garage and 57 spaces are
proposed as on-street parking. In addition, the applicant is proposing to work closely with PSE for the engineering and

PROJECT DESCRIPTION: The applicant, Southport West LLC, is requesting Master Plan Review, Hearing Examiner
Site Plan Review and Environmental (SEPA) Review for the construction of Southport West. Southport West is the
completion of the southerly portion of the Southport Development located at the south end of Lake Washington Blvd N.
The proposed expansion of Southport would be located on the 10.09-acre former Puget Sound Energy (PSE) Substation
and PSE utility parcels (APNs 082305-9191 and -9178). The two (2) parcels are located in the Urban Center-2 (UC-2) zone
and the Urban Design District ‘C’. The site is proposed to be developed as five (5) high-rise buildings with approximately
1,200,000 square feet of office and 50,000 of retail development in multiple phases. The proposed first three phases
would be developed as follows: Phase I – Towers 1 and 2 with the garage podium (July 2023 – July 2027), Phase II –
Towers 3 and 4 with garage podium (July 2027 – July 2031), and Phase III – Tower 5 (post July 2031). Phases 1-3 would
start on the south side of the site (closer to Boeing) and would develop to the north side of the lot (closer to Gene Coulon
Memorial Beach Park). A fourth and final phase is being considered for a sixth tower with 130,000 square feet for office
and retail at the south corner of the development near the intersection of Park Ave N and 757th Ave NE. The phased
development could reach as high as 1.6 million gross square feet. The proposed nine-level development would be built
at the same height and scale as the existing Southport offices with an overall height of approximately 154 feet above
average grade. Parking for 2,207 vehicles would be provided in a shared 4- and 5-level parking garage and 57 spaces are
proposed as on-street parking. In addition, the applicant is proposing to work closely with PSE for the engineering and

capacity needs of the development in order to relocate the powerlines and utility switchgear adjacent to Johns Creek.
Vehicular access to Southport West would be provided by Park Ave N, Lake Washington Blvd N, and the addition of an
internal center road and frontage road.
The site is generally level and consists of gravel yard and asphalt, a Puget Sound Energy switchgear, and an
office/warehouse building. The site contains high seismic hazard areas and the northeast corner of the site contains
Johns Creek and regulated slopes. The soil consists of a loose to medium dense sand, underlain by soft to medium dense
silt, then medium dense to dense sand, very soft silt and clay, and finally dense to very dense silty sand. Groundwater
was observed in the historical exploration at Southport at depths ranging from 3 to 10 feet below existing grade.
Preliminary estimates of cut and fill include approximately 25,000 cubic yards of excavation and 39,200 cubic yards of fill
from an approved source. The depth of excavation is anticipated to not exceed approximately two feet (2’) below ground
level, except for building cores where excavation would be deeper. Stormwater runoff from pollution generating surfaces
would be captured by catch basins and treated in cartridge filter facilities prior to connection into three (3) existing
drainage systems. No significant trees are proposed to be removed. Southport is proposing to plant 115 new trees along
with a variety of shrubs and perennials. The applicant has submitted a Preliminary Geotechnical Report, Technical
Information Report, Traffic Impact Analysis, and Stream Assessment and Final Mitigation Plan with the application.

Towers 3 and 4 with garage podium (July 2027 – July 2031), and Phase III – Tower 5 (post July 2031). Phases 1-3 would
start on the south side of the site (closer to Boeing) and would develop to the north side of the lot (closer to Gene Coulon
Memorial Beach Park). A fourth and final phase is being considered for a sixth tower with 130,000 square feet for office
and retail at the south corner of the development near the intersection of Park Ave N and 757th Ave NE. The phased
development could reach as high as 1.6 million gross square feet. The proposed nine-level development would be built
at the same height and scale as the existing Southport offices with an overall height of approximately 154 feet above
average grade. Parking for 2,207 vehicles would be provided in a shared 4- and 5-level parking garage and 57 spaces are
proposed as on-street parking. In addition, the applicant is proposing to work closely with PSE for the engineering and

Vehicular access to Southport West would be provided by Park Ave N, Lake Washington Blvd N, and the addition of an
internal center road and frontage road.
The site is generally level and consists of gravel yard and asphalt, a Puget Sound Energy switchgear, and an
office/warehouse building. The site contains high seismic hazard areas and the northeast corner of the site contains
Johns Creek and regulated slopes. The soil consists of a loose to medium dense sand, underlain by soft to medium dense
silt, then medium dense to dense sand, very soft silt and clay, and finally dense to very dense silty sand. Groundwater
was observed in the historical exploration at Southport at depths ranging from 3 to 10 feet below existing grade.
Preliminary estimates of cut and fill include approximately 25,000 cubic yards of excavation and 39,200 cubic yards of fill
from an approved source. The depth of excavation is anticipated to not exceed approximately two feet (2’) below ground
level, except for building cores where excavation would be deeper. Stormwater runoff from pollution generating surfaces
would be captured by catch basins and treated in cartridge filter facilities prior to connection into three (3) existing
drainage systems. No significant trees are proposed to be removed. Southport is proposing to plant 115 new trees along
with a variety of shrubs and perennials. The applicant has submitted a Preliminary Geotechnical Report, Technical
Information Report, Traffic Impact Analysis, and Stream Assessment and Final Mitigation Plan with the application.

PROJECT DESCRIPTION: The applicant, Southport West LLC, is requesting Master Plan Review, Hearing Examiner
Site Plan Review and Environmental (SEPA) Review for the construction of Southport West. Southport West is the
completion of the southerly portion of the Southport Development located at the south end of Lake Washington Blvd N.
The proposed expansion of Southport would be located on the 10.09-acre former Puget Sound Energy (PSE) Substation
and PSE utility parcels (APNs 082305-9191 and -9178). The two (2) parcels are located in the Urban Center-2 (UC-2) zone
and the Urban Design District ‘C’. The site is proposed to be developed as five (5) high-rise buildings with approximately
1,200,000 square feet of office and 50,000 of retail development in multiple phases. The proposed first three phases
would be developed as follows: Phase I – Towers 1 and 2 with the garage podium (July 2023 – July 2027), Phase II –
Towers 3 and 4 with garage podium (July 2027 – July 2031), and Phase III – Tower 5 (post July 2031). Phases 1-3 would
start on the south side of the site (closer to Boeing) and would develop to the north side of the lot (closer to Gene Coulon
Memorial Beach Park). A fourth and final phase is being considered for a sixth tower with 130,000 square feet for office
and retail at the south corner of the development near the intersection of Park Ave N and 757th Ave NE. The phased
development could reach as high as 1.6 million gross square feet. The proposed nine-level development would be built
at the same height and scale as the existing Southport offices with an overall height of approximately 154 feet above
average grade. Parking for 2,207 vehicles would be provided in a shared 4- and 5-level parking garage and 57 spaces are
proposed as on-street parking. In addition, the applicant is proposing to work closely with PSE for the engineering and

capacity needs of the development in order to relocate the powerlines and utility switchgear adjacent to Johns Creek.
Vehicular access to Southport West would be provided by Park Ave N, Lake Washington Blvd N, and the addition of an
internal center road and frontage road.
The site is generally level and consists of gravel yard and asphalt, a Puget Sound Energy switchgear, and an
office/warehouse building. The site contains high seismic hazard areas and the northeast corner of the site contains
Johns Creek and regulated slopes. The soil consists of a loose to medium dense sand, underlain by soft to medium dense
silt, then medium dense to dense sand, very soft silt and clay, and finally dense to very dense silty sand. Groundwater
was observed in the historical exploration at Southport at depths ranging from 3 to 10 feet below existing grade.
Preliminary estimates of cut and fill include approximately 25,000 cubic yards of excavation and 39,200 cubic yards of fill
from an approved source. The depth of excavation is anticipated to not exceed approximately two feet (2’) below ground
level, except for building cores where excavation would be deeper. Stormwater runoff from pollution generating surfaces
would be captured by catch basins and treated in cartridge filter facilities prior to connection into three (3) existing
drainage systems. No significant trees are proposed to be removed. Southport is proposing to plant 115 new trees along
with a variety of shrubs and perennials. The applicant has submitted a Preliminary Geotechnical Report, Technical
Information Report, Traffic Impact Analysis, and Stream Assessment and Final Mitigation Plan with the application.

PROJECT DESCRIPTION: The applicant, Southport West LLC, is requesting Master Plan Review, Hearing Examiner
Site Plan Review and Environmental (SEPA) Review for the construction of Southport West. Southport West is the
completion of the southerly portion of the Southport Development located at the south end of Lake Washington Blvd N.
The proposed expansion of Southport would be located on the 10.09-acre former Puget Sound Energy (PSE) Substation
and PSE utility parcels (APNs 082305-9191 and -9178). The two (2) parcels are located in the Urban Center-2 (UC-2) zone
and the Urban Design District ‘C’. The site is proposed to be developed as five (5) high-rise buildings with approximately
1,200,000 square feet of office and 50,000 of retail development in multiple phases. The proposed first three phases
would be developed as follows: Phase I – Towers 1 and 2 with the garage podium (July 2023 – July 2027), Phase II –
Towers 3 and 4 with garage podium (July 2027 – July 2031), and Phase III – Tower 5 (post July 2031). Phases 1-3 would
start on the south side of the site (closer to Boeing) and would develop to the north side of the lot (closer to Gene Coulon
Memorial Beach Park). A fourth and final phase is being considered for a sixth tower with 130,000 square feet for office
and retail at the south corner of the development near the intersection of Park Ave N and 757th Ave NE. The phased
development could reach as high as 1.6 million gross square feet. The proposed nine-level development would be built
at the same height and scale as the existing Southport offices with an overall height of approximately 154 feet above
average grade. Parking for 2,207 vehicles would be provided in a shared 4- and 5-level parking garage and 57 spaces are
proposed as on-street parking. In addition, the applicant is proposing to work closely with PSE for the engineering and

capacity needs of the development in order to relocate the powerlines and utility switchgear adjacent to Johns Creek.
Vehicular access to Southport West would be provided by Park Ave N, Lake Washington Blvd N, and the addition of an
internal center road and frontage road.
The site is generally level and consists of gravel yard and asphalt, a Puget Sound Energy switchgear, and an
office/warehouse building. The site contains high seismic hazard areas and the northeast corner of the site contains
Johns Creek and regulated slopes. The soil consists of a loose to medium dense sand, underlain by soft to medium dense
silt, then medium dense to dense sand, very soft silt and clay, and finally dense to very dense silty sand. Groundwater
was observed in the historical exploration at Southport at depths ranging from 3 to 10 feet below existing grade.
Preliminary estimates of cut and fill include approximately 25,000 cubic yards of excavation and 39,200 cubic yards of fill
from an approved source. The depth of excavation is anticipated to not exceed approximately two feet (2’) below ground
level, except for building cores where excavation would be deeper. Stormwater runoff from pollution generating surfaces
would be captured by catch basins and treated in cartridge filter facilities prior to connection into three (3) existing
drainage systems. No significant trees are proposed to be removed. Southport is proposing to plant 115 new trees along
with a variety of shrubs and perennials. The applicant has submitted a Preliminary Geotechnical Report, Technical
Information Report, Traffic Impact Analysis, and Stream Assessment and Final Mitigation Plan with the application.

office/warehouse building. The site contains high seismic hazard areas and the northeast corner of the site contains
Johns Creek and regulated slopes. The soil consists of a loose to medium dense sand, underlain by soft to medium dense
silt, then medium dense to dense sand, very soft silt and clay, and finally dense to very dense silty sand. Groundwater
was observed in the historical exploration at Southport at depths ranging from 3 to 10 feet below existing grade.
Preliminary estimates of cut and fill include approximately 25,000 cubic yards of excavation and 39,200 cubic yards of fill
from an approved source. The depth of excavation is anticipated to not exceed approximately two feet (2’) below ground
level, except for building cores where excavation would be deeper. Stormwater runoff from pollution generating surfaces
would be captured by catch basins and treated in cartridge filter facilities prior to connection into three (3) existing
drainage systems. No significant trees are proposed to be removed. Southport is proposing to plant 115 new trees along
with a variety of shrubs and perennials. The applicant has submitted a Preliminary Geotechnical Report, Technical
Information Report, Traffic Impact Analysis, and Stream Assessment and Final Mitigation Plan with the application.

Site Plan Review and Environmental (SEPA) Review for the construction of Southport West. Southport West is the
completion of the southerly portion of the Southport Development located at the south end of Lake Washington Blvd N.
The proposed expansion of Southport would be located on the 10.09-acre former Puget Sound Energy (PSE) Substation
and PSE utility parcels (APNs 082305-9191 and -9178). The two (2) parcels are located in the Urban Center-2 (UC-2) zone
and the Urban Design District ‘C’. The site is proposed to be developed as five (5) high-rise buildings with approximately
1,200,000 square feet of office and 50,000 of retail development in multiple phases. The proposed first three phases
would be developed as follows: Phase I – Towers 1 and 2 with the garage podium (July 2023 – July 2027), Phase II –
Towers 3 and 4 with garage podium (July 2027 – July 2031), and Phase III – Tower 5 (post July 2031). Phases 1-3 would
start on the south side of the site (closer to Boeing) and would develop to the north side of the lot (closer to Gene Coulon
Memorial Beach Park). A fourth and final phase is being considered for a sixth tower with 130,000 square feet for office
and retail at the south corner of the development near the intersection of Park Ave N and 757th Ave NE. The phased
development could reach as high as 1.6 million gross square feet. The proposed nine-level development would be built
at the same height and scale as the existing Southport offices with an overall height of approximately 154 feet above
average grade. Parking for 2,207 vehicles would be provided in a shared 4- and 5-level parking garage and 57 spaces are
proposed as on-street parking. In addition, the applicant is proposing to work closely with PSE for the engineering and

PROJECT DESCRIPTION: The applicant, Southport West LLC, is requesting Master Plan Review, Hearing Examiner
Site Plan Review and Environmental (SEPA) Review for the construction of Southport West. Southport West is the
completion of the southerly portion of the Southport Development located at the south end of Lake Washington Blvd N.
The proposed expansion of Southport would be located on the 10.09-acre former Puget Sound Energy (PSE) Substation
and PSE utility parcels (APNs 082305-9191 and -9178). The two (2) parcels are located in the Urban Center-2 (UC-2) zone
and the Urban Design District ‘C’. The site is proposed to be developed as five (5) high-rise buildings with approximately
1,200,000 square feet of office and 50,000 of retail development in multiple phases. The proposed first three phases
would be developed as follows: Phase I – Towers 1 and 2 with the garage podium (July 2023 – July 2027), Phase II –
Towers 3 and 4 with garage podium (July 2027 – July 2031), and Phase III – Tower 5 (post July 2031). Phases 1-3 would
start on the south side of the site (closer to Boeing) and would develop to the north side of the lot (closer to Gene Coulon
Memorial Beach Park). A fourth and final phase is being considered for a sixth tower with 130,000 square feet for office
and retail at the south corner of the development near the intersection of Park Ave N and 757th Ave NE. The phased
development could reach as high as 1.6 million gross square feet. The proposed nine-level development would be built
at the same height and scale as the existing Southport offices with an overall height of approximately 154 feet above
average grade. Parking for 2,207 vehicles would be provided in a shared 4- and 5-level parking garage and 57 spaces are
proposed as on-street parking. In addition, the applicant is proposing to work closely with PSE for the engineering and

capacity needs of the development in order to relocate the powerlines and utility switchgear adjacent to Johns Creek.
Vehicular access to Southport West would be provided by Park Ave N, Lake Washington Blvd N, and the addition of an
internal center road and frontage road.
The site is generally level and consists of gravel yard and asphalt, a Puget Sound Energy switchgear, and an
office/warehouse building. The site contains high seismic hazard areas and the northeast corner of the site contains
Johns Creek and regulated slopes. The soil consists of a loose to medium dense sand, underlain by soft to medium dense
silt, then medium dense to dense sand, very soft silt and clay, and finally dense to very dense silty sand. Groundwater
was observed in the historical exploration at Southport at depths ranging from 3 to 10 feet below existing grade.
Preliminary estimates of cut and fill include approximately 25,000 cubic yards of excavation and 39,200 cubic yards of fill
from an approved source. The depth of excavation is anticipated to not exceed approximately two feet (2’) below ground
level, except for building cores where excavation would be deeper. Stormwater runoff from pollution generating surfaces
would be captured by catch basins and treated in cartridge filter facilities prior to connection into three (3) existing
drainage systems. No significant trees are proposed to be removed. Southport is proposing to plant 115 new trees along
with a variety of shrubs and perennials. The applicant has submitted a Preliminary Geotechnical Report, Technical
Information Report, Traffic Impact Analysis, and Stream Assessment and Final Mitigation Plan with the application.

capacity needs of the development in order to relocate the powerlines and utility switchgear adjacent to Johns Creek.
Vehicular access to Southport West would be provided by Park Ave N, Lake Washington Blvd N, and the addition of an
internal center road and frontage road.
The site is generally level and consists of gravel yard and asphalt, a Puget Sound Energy switchgear, and an
office/warehouse building. The site contains high seismic hazard areas and the northeast corner of the site contains
Johns Creek and regulated slopes. The soil consists of a loose to medium dense sand, underlain by soft to medium dense
silt, then medium dense to dense sand, very soft silt and clay, and finally dense to very dense silty sand. Groundwater
was observed in the historical exploration at Southport at depths ranging from 3 to 10 feet below existing grade.
Preliminary estimates of cut and fill include approximately 25,000 cubic yards of excavation and 39,200 cubic yards of fill
from an approved source. The depth of excavation is anticipated to not exceed approximately two feet (2’) below ground
level, except for building cores where excavation would be deeper. Stormwater runoff from pollution generating surfaces
would be captured by catch basins and treated in cartridge filter facilities prior to connection into three (3) existing
drainage systems. No significant trees are proposed to be removed. Southport is proposing to plant 115 new trees along
with a variety of shrubs and perennials. The applicant has submitted a Preliminary Geotechnical Report, Technical
Information Report, Traffic Impact Analysis, and Stream Assessment and Final Mitigation Plan with the application.

The proposed expansion of Southport would be located on the 10.09-acre former Puget Sound Energy (PSE) Substation
and PSE utility parcels (APNs 082305-9191 and -9178). The two (2) parcels are located in the Urban Center-2 (UC-2) zone
and the Urban Design District ‘C’. The site is proposed to be developed as five (5) high-rise buildings with approximately
1,200,000 square feet of office and 50,000 of retail development in multiple phases. The proposed first three phases
would be developed as follows: Phase I – Towers 1 and 2 with the garage podium (July 2023 – July 2027), Phase II –
Towers 3 and 4 with garage podium (July 2027 – July 2031), and Phase III – Tower 5 (post July 2031). Phases 1-3 would
start on the south side of the site (closer to Boeing) and would develop to the north side of the lot (closer to Gene Coulon
Memorial Beach Park). A fourth and final phase is being considered for a sixth tower with 130,000 square feet for office
and retail at the south corner of the development near the intersection of Park Ave N and 757th Ave NE. The phased
development could reach as high as 1.6 million gross square feet. The proposed nine-level development would be built
at the same height and scale as the existing Southport offices with an overall height of approximately 154 feet above
average grade. Parking for 2,207 vehicles would be provided in a shared 4- and 5-level parking garage and 57 spaces are

PROJECT DESCRIPTION: The applicant, Southport West LLC, is requesting Master Plan Review, Hearing Examiner
Site Plan Review and Environmental (SEPA) Review for the construction of Southport West. Southport West is the
completion of the southerly portion of the Southport Development located at the south end of Lake Washington Blvd N.
The proposed expansion of Southport would be located on the 10.09-acre former Puget Sound Energy (PSE) Substation
and PSE utility parcels (APNs 082305-9191 and -9178). The two (2) parcels are located in the Urban Center-2 (UC-2) zone
and the Urban Design District ‘C’. The site is proposed to be developed as five (5) high-rise buildings with approximately
1,200,000 square feet of office and 50,000 of retail development in multiple phases. The proposed first three phases
would be developed as follows: Phase I – Towers 1 and 2 with the garage podium (July 2023 – July 2027), Phase II –
Towers 3 and 4 with garage podium (July 2027 – July 2031), and Phase III – Tower 5 (post July 2031). Phases 1-3 would
start on the south side of the site (closer to Boeing) and would develop to the north side of the lot (closer to Gene Coulon
Memorial Beach Park). A fourth and final phase is being considered for a sixth tower with 130,000 square feet for office
and retail at the south corner of the development near the intersection of Park Ave N and 757th Ave NE. The phased
development could reach as high as 1.6 million gross square feet. The proposed nine-level development would be built
at the same height and scale as the existing Southport offices with an overall height of approximately 154 feet above
average grade. Parking for 2,207 vehicles would be provided in a shared 4- and 5-level parking garage and 57 spaces are
proposed as on-street parking. In addition, the applicant is proposing to work closely with PSE for the engineering and

capacity needs of the development in order to relocate the powerlines and utility switchgear adjacent to Johns Creek.
Vehicular access to Southport West would be provided by Park Ave N, Lake Washington Blvd N, and the addition of an
internal center road and frontage road.
The site is generally level and consists of gravel yard and asphalt, a Puget Sound Energy switchgear, and an
office/warehouse building. The site contains high seismic hazard areas and the northeast corner of the site contains
Johns Creek and regulated slopes. The soil consists of a loose to medium dense sand, underlain by soft to medium dense
silt, then medium dense to dense sand, very soft silt and clay, and finally dense to very dense silty sand. Groundwater
was observed in the historical exploration at Southport at depths ranging from 3 to 10 feet below existing grade.
Preliminary estimates of cut and fill include approximately 25,000 cubic yards of excavation and 39,200 cubic yards of fill
from an approved source. The depth of excavation is anticipated to not exceed approximately two feet (2’) below ground
level, except for building cores where excavation would be deeper. Stormwater runoff from pollution generating surfaces
would be captured by catch basins and treated in cartridge filter facilities prior to connection into three (3) existing
drainage systems. No significant trees are proposed to be removed. Southport is proposing to plant 115 new trees along
with a variety of shrubs and perennials. The applicant has submitted a Preliminary Geotechnical Report, Technical
Information Report, Traffic Impact Analysis, and Stream Assessment and Final Mitigation Plan with the application.

and PSE utility parcels (APNs 082305-9191 and -9178). The two (2) parcels are located in the Urban Center-2 (UC-2) zone
and the Urban Design District ‘C’. The site is proposed to be developed as five (5) high-rise buildings with approximately
1,200,000 square feet of office and 50,000 of retail development in multiple phases. The proposed first three phases
would be developed as follows: Phase I – Towers 1 and 2 with the garage podium (July 2023 – July 2027), Phase II –
Towers 3 and 4 with garage podium (July 2027 – July 2031), and Phase III – Tower 5 (post July 2031). Phases 1-3 would
start on the south side of the site (closer to Boeing) and would develop to the north side of the lot (closer to Gene Coulon
Memorial Beach Park). A fourth and final phase is being considered for a sixth tower with 130,000 square feet for office
and retail at the south corner of the development near the intersection of Park Ave N and 757th Ave NE. The phased
development could reach as high as 1.6 million gross square feet. The proposed nine-level development would be built
at the same height and scale as the existing Southport offices with an overall height of approximately 154 feet above
average grade. Parking for 2,207 vehicles would be provided in a shared 4- and 5-level parking garage and 57 spaces are
proposed as on-street parking. In addition, the applicant is proposing to work closely with PSE for the engineering and

capacity needs of the development in order to relocate the powerlines and utility switchgear adjacent to Johns Creek.
Vehicular access to Southport West would be provided by Park Ave N, Lake Washington Blvd N, and the addition of an
internal center road and frontage road.
The site is generally level and consists of gravel yard and asphalt, a Puget Sound Energy switchgear, and an
office/warehouse building. The site contains high seismic hazard areas and the northeast corner of the site contains
Johns Creek and regulated slopes. The soil consists of a loose to medium dense sand, underlain by soft to medium dense
silt, then medium dense to dense sand, very soft silt and clay, and finally dense to very dense silty sand. Groundwater
was observed in the historical exploration at Southport at depths ranging from 3 to 10 feet below existing grade.
Preliminary estimates of cut and fill include approximately 25,000 cubic yards of excavation and 39,200 cubic yards of fill
from an approved source. The depth of excavation is anticipated to not exceed approximately two feet (2’) below ground
level, except for building cores where excavation would be deeper. Stormwater runoff from pollution generating surfaces
would be captured by catch basins and treated in cartridge filter facilities prior to connection into three (3) existing
drainage systems. No significant trees are proposed to be removed. Southport is proposing to plant 115 new trees along
with a variety of shrubs and perennials. The applicant has submitted a Preliminary Geotechnical Report, Technical
Information Report, Traffic Impact Analysis, and Stream Assessment and Final Mitigation Plan with the application.

PROJECT DESCRIPTION: The applicant, Southport West LLC, is requesting Master Plan Review, Hearing Examiner
Site Plan Review and Environmental (SEPA) Review for the construction of Southport West. Southport West is the
completion of the southerly portion of the Southport Development located at the south end of Lake Washington Blvd N.
The proposed expansion of Southport would be located on the 10.09-acre former Puget Sound Energy (PSE) Substation
and PSE utility parcels (APNs 082305-9191 and -9178). The two (2) parcels are located in the Urban Center-2 (UC-2) zone
and the Urban Design District ‘C’. The site is proposed to be developed as five (5) high-rise buildings with approximately
1,200,000 square feet of office and 50,000 of retail development in multiple phases. The proposed first three phases
would be developed as follows: Phase I – Towers 1 and 2 with the garage podium (July 2023 – July 2027), Phase II –
Towers 3 and 4 with garage podium (July 2027 – July 2031), and Phase III – Tower 5 (post July 2031). Phases 1-3 would
start on the south side of the site (closer to Boeing) and would develop to the north side of the lot (closer to Gene Coulon
Memorial Beach Park). A fourth and final phase is being considered for a sixth tower with 130,000 square feet for office
and retail at the south corner of the development near the intersection of Park Ave N and 757th Ave NE. The phased
development could reach as high as 1.6 million gross square feet. The proposed nine-level development would be built
at the same height and scale as the existing Southport offices with an overall height of approximately 154 feet above
average grade. Parking for 2,207 vehicles would be provided in a shared 4- and 5-level parking garage and 57 spaces are
proposed as on-street parking. In addition, the applicant is proposing to work closely with PSE for the engineering and

Vehicular access to Southport West would be provided by Park Ave N, Lake Washington Blvd N, and the addition of an
internal center road and frontage road.
The site is generally level and consists of gravel yard and asphalt, a Puget Sound Energy switchgear, and an
office/warehouse building. The site contains high seismic hazard areas and the northeast corner of the site contains
Johns Creek and regulated slopes. The soil consists of a loose to medium dense sand, underlain by soft to medium dense
silt, then medium dense to dense sand, very soft silt and clay, and finally dense to very dense silty sand. Groundwater
was observed in the historical exploration at Southport at depths ranging from 3 to 10 feet below existing grade.
Preliminary estimates of cut and fill include approximately 25,000 cubic yards of excavation and 39,200 cubic yards of fill
from an approved source. The depth of excavation is anticipated to not exceed approximately two feet (2’) below ground
level, except for building cores where excavation would be deeper. Stormwater runoff from pollution generating surfaces
would be captured by catch basins and treated in cartridge filter facilities prior to connection into three (3) existing
drainage systems. No significant trees are proposed to be removed. Southport is proposing to plant 115 new trees along
with a variety of shrubs and perennials. The applicant has submitted a Preliminary Geotechnical Report, Technical
Information Report, Traffic Impact Analysis, and Stream Assessment and Final Mitigation Plan with the application.

PROJECT DESCRIPTION: The applicant, Southport West LLC, is requesting Master Plan Review, Hearing Examiner
Site Plan Review and Environmental (SEPA) Review for the construction of Southport West. Southport West is the
completion of the southerly portion of the Southport Development located at the south end of Lake Washington Blvd N.
The proposed expansion of Southport would be located on the 10.09-acre former Puget Sound Energy (PSE) Substation
and PSE utility parcels (APNs 082305-9191 and -9178). The two (2) parcels are located in the Urban Center-2 (UC-2) zone
and the Urban Design District ‘C’. The site is proposed to be developed as five (5) high-rise buildings with approximately
1,200,000 square feet of office and 50,000 of retail development in multiple phases. The proposed first three phases
would be developed as follows: Phase I – Towers 1 and 2 with the garage podium (July 2023 – July 2027), Phase II –
Towers 3 and 4 with garage podium (July 2027 – July 2031), and Phase III – Tower 5 (post July 2031). Phases 1-3 would
start on the south side of the site (closer to Boeing) and would develop to the north side of the lot (closer to Gene Coulon
Memorial Beach Park). A fourth and final phase is being considered for a sixth tower with 130,000 square feet for office
and retail at the south corner of the development near the intersection of Park Ave N and 757th Ave NE. The phased
development could reach as high as 1.6 million gross square feet. The proposed nine-level development would be built
at the same height and scale as the existing Southport offices with an overall height of approximately 154 feet above
average grade. Parking for 2,207 vehicles would be provided in a shared 4- and 5-level parking garage and 57 spaces are
proposed as on-street parking. In addition, the applicant is proposing to work closely with PSE for the engineering and

capacity needs of the development in order to relocate the powerlines and utility switchgear adjacent to Johns Creek.
Vehicular access to Southport West would be provided by Park Ave N, Lake Washington Blvd N, and the addition of an
internal center road and frontage road.
The site is generally level and consists of gravel yard and asphalt, a Puget Sound Energy switchgear, and an
office/warehouse building. The site contains high seismic hazard areas and the northeast corner of the site contains
Johns Creek and regulated slopes. The soil consists of a loose to medium dense sand, underlain by soft to medium dense
silt, then medium dense to dense sand, very soft silt and clay, and finally dense to very dense silty sand. Groundwater
was observed in the historical exploration at Southport at depths ranging from 3 to 10 feet below existing grade.
Preliminary estimates of cut and fill include approximately 25,000 cubic yards of excavation and 39,200 cubic yards of fill
from an approved source. The depth of excavation is anticipated to not exceed approximately two feet (2’) below ground
level, except for building cores where excavation would be deeper. Stormwater runoff from pollution generating surfaces
would be captured by catch basins and treated in cartridge filter facilities prior to connection into three (3) existing
drainage systems. No significant trees are proposed to be removed. Southport is proposing to plant 115 new trees along
with a variety of shrubs and perennials. The applicant has submitted a Preliminary Geotechnical Report, Technical
Information Report, Traffic Impact Analysis, and Stream Assessment and Final Mitigation Plan with the application.

capacity needs of the development in order to relocate the powerlines and utility switchgear adjacent to Johns Creek.
Vehicular access to Southport West would be provided by Park Ave N, Lake Washington Blvd N, and the addition of an
internal center road and frontage road.
The site is generally level and consists of gravel yard and asphalt, a Puget Sound Energy switchgear, and an
office/warehouse building. The site contains high seismic hazard areas and the northeast corner of the site contains
Johns Creek and regulated slopes. The soil consists of a loose to medium dense sand, underlain by soft to medium dense
silt, then medium dense to dense sand, very soft silt and clay, and finally dense to very dense silty sand. Groundwater
was observed in the historical exploration at Southport at depths ranging from 3 to 10 feet below existing grade.
Preliminary estimates of cut and fill include approximately 25,000 cubic yards of excavation and 39,200 cubic yards of fill
from an approved source. The depth of excavation is anticipated to not exceed approximately two feet (2’) below ground
level, except for building cores where excavation would be deeper. Stormwater runoff from pollution generating surfaces
would be captured by catch basins and treated in cartridge filter facilities prior to connection into three (3) existing
drainage systems. No significant trees are proposed to be removed. Southport is proposing to plant 115 new trees along
with a variety of shrubs and perennials. The applicant has submitted a Preliminary Geotechnical Report, Technical
Information Report, Traffic Impact Analysis, and Stream Assessment and Final Mitigation Plan with the application.

Site Plan Review and Environmental (SEPA) Review for the construction of Southport West. Southport West is the
completion of the southerly portion of the Southport Development located at the south end of Lake Washington Blvd N.
The proposed expansion of Southport would be located on the 10.09-acre former Puget Sound Energy (PSE) Substation
and PSE utility parcels (APNs 082305-9191 and -9178). The two (2) parcels are located in the Urban Center-2 (UC-2) zone
and the Urban Design District ‘C’. The site is proposed to be developed as five (5) high-rise buildings with approximately
1,200,000 square feet of office and 50,000 of retail development in multiple phases. The proposed first three phases
would be developed as follows: Phase I – Towers 1 and 2 with the garage podium (July 2023 – July 2027), Phase II –
Towers 3 and 4 with garage podium (July 2027 – July 2031), and Phase III – Tower 5 (post July 2031). Phases 1-3 would
start on the south side of the site (closer to Boeing) and would develop to the north side of the lot (closer to Gene Coulon
Memorial Beach Park). A fourth and final phase is being considered for a sixth tower with 130,000 square feet for office
and retail at the south corner of the development near the intersection of Park Ave N and 757th Ave NE. The phased
development could reach as high as 1.6 million gross square feet. The proposed nine-level development would be built
at the same height and scale as the existing Southport offices with an overall height of approximately 154 feet above
average grade. Parking for 2,207 vehicles would be provided in a shared 4- and 5-level parking garage and 57 spaces are
proposed as on-street parking. In addition, the applicant is proposing to work closely with PSE for the engineering and

PROJECT DESCRIPTION: The applicant, Southport West LLC, is requesting Master Plan Review, Hearing Examiner
Site Plan Review and Environmental (SEPA) Review for the construction of Southport West. Southport West is the
completion of the southerly portion of the Southport Development located at the south end of Lake Washington Blvd N.
The proposed expansion of Southport would be located on the 10.09-acre former Puget Sound Energy (PSE) Substation
and PSE utility parcels (APNs 082305-9191 and -9178). The two (2) parcels are located in the Urban Center-2 (UC-2) zone
and the Urban Design District ‘C’. The site is proposed to be developed as five (5) high-rise buildings with approximately
1,200,000 square feet of office and 50,000 of retail development in multiple phases. The proposed first three phases
would be developed as follows: Phase I – Towers 1 and 2 with the garage podium (July 2023 – July 2027), Phase II –
Towers 3 and 4 with garage podium (July 2027 – July 2031), and Phase III – Tower 5 (post July 2031). Phases 1-3 would
start on the south side of the site (closer to Boeing) and would develop to the north side of the lot (closer to Gene Coulon
Memorial Beach Park). A fourth and final phase is being considered for a sixth tower with 130,000 square feet for office
and retail at the south corner of the development near the intersection of Park Ave N and 757th Ave NE. The phased
development could reach as high as 1.6 million gross square feet. The proposed nine-level development would be built
at the same height and scale as the existing Southport offices with an overall height of approximately 154 feet above
average grade. Parking for 2,207 vehicles would be provided in a shared 4- and 5-level parking garage and 57 spaces are
proposed as on-street parking. In addition, the applicant is proposing to work closely with PSE for the engineering and

capacity needs of the development in order to relocate the powerlines and utility switchgear adjacent to Johns Creek.
Vehicular access to Southport West would be provided by Park Ave N, Lake Washington Blvd N, and the addition of an
internal center road and frontage road.
The site is generally level and consists of gravel yard and asphalt, a Puget Sound Energy switchgear, and an
office/warehouse building. The site contains high seismic hazard areas and the northeast corner of the site contains
Johns Creek and regulated slopes. The soil consists of a loose to medium dense sand, underlain by soft to medium dense
silt, then medium dense to dense sand, very soft silt and clay, and finally dense to very dense silty sand. Groundwater
was observed in the historical exploration at Southport at depths ranging from 3 to 10 feet below existing grade.
Preliminary estimates of cut and fill include approximately 25,000 cubic yards of excavation and 39,200 cubic yards of fill
from an approved source. The depth of excavation is anticipated to not exceed approximately two feet (2’) below ground
level, except for building cores where excavation would be deeper. Stormwater runoff from pollution generating surfaces
would be captured by catch basins and treated in cartridge filter facilities prior to connection into three (3) existing
drainage systems. No significant trees are proposed to be removed. Southport is proposing to plant 115 new trees along
with a variety of shrubs and perennials. The applicant has submitted a Preliminary Geotechnical Report, Technical
Information Report, Traffic Impact Analysis, and Stream Assessment and Final Mitigation Plan with the application.

Vehicular access to Southport West would be provided by Park Ave N, Lake Washington Blvd N, and the addition of an
internal center road and frontage road.
The site is generally level and consists of gravel yard and asphalt, a Puget Sound Energy switchgear, and an
office/warehouse building. The site contains high seismic hazard areas and the northeast corner of the site contains
Johns Creek and regulated slopes. The soil consists of a loose to medium dense sand, underlain by soft to medium dense
silt, then medium dense to dense sand, very soft silt and clay, and finally dense to very dense silty sand. Groundwater
was observed in the historical exploration at Southport at depths ranging from 3 to 10 feet below existing grade.
Preliminary estimates of cut and fill include approximately 25,000 cubic yards of excavation and 39,200 cubic yards of fill
from an approved source. The depth of excavation is anticipated to not exceed approximately two feet (2’) below ground
level, except for building cores where excavation would be deeper. Stormwater runoff from pollution generating surfaces
would be captured by catch basins and treated in cartridge filter facilities prior to connection into three (3) existing
drainage systems. No significant trees are proposed to be removed. Southport is proposing to plant 115 new trees along
with a variety of shrubs and perennials. The applicant has submitted a Preliminary Geotechnical Report, Technical
Information Report, Traffic Impact Analysis, and Stream Assessment and Final Mitigation Plan with the application.

PROJECT DESCRIPTION: The applicant, Southport West LLC, is requesting Master Plan Review, Hearing Examiner
Site Plan Review and Environmental (SEPA) Review for the construction of Southport West. Southport West is the
completion of the southerly portion of the Southport Development located at the south end of Lake Washington Blvd N.
The proposed expansion of Southport would be located on the 10.09-acre former Puget Sound Energy (PSE) Substation
and PSE utility parcels (APNs 082305-9191 and -9178). The two (2) parcels are located in the Urban Center-2 (UC-2) zone
and the Urban Design District ‘C’. The site is proposed to be developed as five (5) high-rise buildings with approximately
1,200,000 square feet of office and 50,000 of retail development in multiple phases. The proposed first three phases
would be developed as follows: Phase I – Towers 1 and 2 with the garage podium (July 2023 – July 2027), Phase II –
Towers 3 and 4 with garage podium (July 2027 – July 2031), and Phase III – Tower 5 (post July 2031). Phases 1-3 would
start on the south side of the site (closer to Boeing) and would develop to the north side of the lot (closer to Gene Coulon
Memorial Beach Park). A fourth and final phase is being considered for a sixth tower with 130,000 square feet for office
and retail at the south corner of the development near the intersection of Park Ave N and 757th Ave NE. The phased
development could reach as high as 1.6 million gross square feet. The proposed nine-level development would be built
at the same height and scale as the existing Southport offices with an overall height of approximately 154 feet above
average grade. Parking for 2,207 vehicles would be provided in a shared 4- and 5-level parking garage and 57 spaces are
proposed as on-street parking. In addition, the applicant is proposing to work closely with PSE for the engineering and

capacity needs of the development in order to relocate the powerlines and utility switchgear adjacent to Johns Creek.
Vehicular access to Southport West would be provided by Park Ave N, Lake Washington Blvd N, and the addition of an
internal center road and frontage road.
The site is generally level and consists of gravel yard and asphalt, a Puget Sound Energy switchgear, and an
office/warehouse building. The site contains high seismic hazard areas and the northeast corner of the site contains
Johns Creek and regulated slopes. The soil consists of a loose to medium dense sand, underlain by soft to medium dense
silt, then medium dense to dense sand, very soft silt and clay, and finally dense to very dense silty sand. Groundwater
was observed in the historical exploration at Southport at depths ranging from 3 to 10 feet below existing grade.
Preliminary estimates of cut and fill include approximately 25,000 cubic yards of excavation and 39,200 cubic yards of fill
from an approved source. The depth of excavation is anticipated to not exceed approximately two feet (2’) below ground
level, except for building cores where excavation would be deeper. Stormwater runoff from pollution generating surfaces
would be captured by catch basins and treated in cartridge filter facilities prior to connection into three (3) existing
drainage systems. No significant trees are proposed to be removed. Southport is proposing to plant 115 new trees along
with a variety of shrubs and perennials. The applicant has submitted a Preliminary Geotechnical Report, Technical
Information Report, Traffic Impact Analysis, and Stream Assessment and Final Mitigation Plan with the application.

PROJECT DESCRIPTION: The applicant, Southport West LLC, is requesting Master Plan Review, Hearing Examiner
Site Plan Review and Environmental (SEPA) Review for the construction of Southport West. Southport West is the
completion of the southerly portion of the Southport Development located at the south end of Lake Washington Blvd N.
The proposed expansion of Southport would be located on the 10.09-acre former Puget Sound Energy (PSE) Substation
and PSE utility parcels (APNs 082305-9191 and -9178). The two (2) parcels are located in the Urban Center-2 (UC-2) zone
and the Urban Design District ‘C’. The site is proposed to be developed as five (5) high-rise buildings with approximately
1,200,000 square feet of office and 50,000 of retail development in multiple phases. The proposed first three phases
would be developed as follows: Phase I – Towers 1 and 2 with the garage podium (July 2023 – July 2027), Phase II –
Towers 3 and 4 with garage podium (July 2027 – July 2031), and Phase III – Tower 5 (post July 2031). Phases 1-3 would
start on the south side of the site (closer to Boeing) and would develop to the north side of the lot (closer to Gene Coulon
Memorial Beach Park). A fourth and final phase is being considered for a sixth tower with 130,000 square feet for office
and retail at the south corner of the development near the intersection of Park Ave N and 757th Ave NE. The phased
development could reach as high as 1.6 million gross square feet. The proposed nine-level development would be built
at the same height and scale as the existing Southport offices with an overall height of approximately 154 feet above
average grade. Parking for 2,207 vehicles would be provided in a shared 4- and 5-level parking garage and 57 spaces are
proposed as on-street parking. In addition, the applicant is proposing to work closely with PSE for the engineering and

capacity needs of the development in order to relocate the powerlines and utility switchgear adjacent to Johns Creek.
Vehicular access to Southport West would be provided by Park Ave N, Lake Washington Blvd N, and the addition of an
internal center road and frontage road.
The site is generally level and consists of gravel yard and asphalt, a Puget Sound Energy switchgear, and an
office/warehouse building. The site contains high seismic hazard areas and the northeast corner of the site contains
Johns Creek and regulated slopes. The soil consists of a loose to medium dense sand, underlain by soft to medium dense
silt, then medium dense to dense sand, very soft silt and clay, and finally dense to very dense silty sand. Groundwater
was observed in the historical exploration at Southport at depths ranging from 3 to 10 feet below existing grade.
Preliminary estimates of cut and fill include approximately 25,000 cubic yards of excavation and 39,200 cubic yards of fill
from an approved source. The depth of excavation is anticipated to not exceed approximately two feet (2’) below ground
level, except for building cores where excavation would be deeper. Stormwater runoff from pollution generating surfaces
would be captured by catch basins and treated in cartridge filter facilities prior to connection into three (3) existing
drainage systems. No significant trees are proposed to be removed. Southport is proposing to plant 115 new trees along
with a variety of shrubs and perennials. The applicant has submitted a Preliminary Geotechnical Report, Technical
Information Report, Traffic Impact Analysis, and Stream Assessment and Final Mitigation Plan with the application.

PROJECT DESCRIPTION: The applicant, Southport West LLC, is requesting Master Plan Review, Hearing Examiner
Site Plan Review and Environmental (SEPA) Review for the construction of Southport West. Southport West is the
completion of the southerly portion of the Southport Development located at the south end of Lake Washington Blvd N.
The proposed expansion of Southport would be located on the 10.09-acre former Puget Sound Energy (PSE) Substation
and PSE utility parcels (APNs 082305-9191 and -9178). The two (2) parcels are located in the Urban Center-2 (UC-2) zone
and the Urban Design District ‘C’. The site is proposed to be developed as five (5) high-rise buildings with approximately
1,200,000 square feet of office and 50,000 of retail development in multiple phases. The proposed first three phases
would be developed as follows: Phase I – Towers 1 and 2 with the garage podium (July 2023 – July 2027), Phase II –
Towers 3 and 4 with garage podium (July 2027 – July 2031), and Phase III – Tower 5 (post July 2031). Phases 1-3 would
start on the south side of the site (closer to Boeing) and would develop to the north side of the lot (closer to Gene Coulon
Memorial Beach Park). A fourth and final phase is being considered for a sixth tower with 130,000 square feet for office
and retail at the south corner of the development near the intersection of Park Ave N and 757th Ave NE. The phased
development could reach as high as 1.6 million gross square feet. The proposed nine-level development would be built
at the same height and scale as the existing Southport offices with an overall height of approximately 154 feet above
average grade. Parking for 2,207 vehicles would be provided in a shared 4- and 5-level parking garage and 57 spaces are
proposed as on-street parking. In addition, the applicant is proposing to work closely with PSE for the engineering and

Vehicular access to Southport West would be provided by Park Ave N, Lake Washington Blvd N, and the addition of an
internal center road and frontage road.
The site is generally level and consists of gravel yard and asphalt, a Puget Sound Energy switchgear, and an
office/warehouse building. The site contains high seismic hazard areas and the northeast corner of the site contains
Johns Creek and regulated slopes. The soil consists of a loose to medium dense sand, underlain by soft to medium dense
silt, then medium dense to dense sand, very soft silt and clay, and finally dense to very dense silty sand. Groundwater
was observed in the historical exploration at Southport at depths ranging from 3 to 10 feet below existing grade.
Preliminary estimates of cut and fill include approximately 25,000 cubic yards of excavation and 39,200 cubic yards of fill
from an approved source. The depth of excavation is anticipated to not exceed approximately two feet (2’) below ground
level, except for building cores where excavation would be deeper. Stormwater runoff from pollution generating surfaces
would be captured by catch basins and treated in cartridge filter facilities prior to connection into three (3) existing

PROJECT DESCRIPTION: The applicant, Southport West LLC, is requesting Master Plan Review, Hearing Examiner
Site Plan Review and Environmental (SEPA) Review for the construction of Southport West. Southport West is the
completion of the southerly portion of the Southport Development located at the south end of Lake Washington Blvd N.
The proposed expansion of Southport would be located on the 10.09-acre former Puget Sound Energy (PSE) Substation
and PSE utility parcels (APNs 082305-9191 and -9178). The two (2) parcels are located in the Urban Center-2 (UC-2) zone
and the Urban Design District ‘C’. The site is proposed to be developed as five (5) high-rise buildings with approximately
1,200,000 square feet of office and 50,000 of retail development in multiple phases. The proposed first three phases
would be developed as follows: Phase I – Towers 1 and 2 with the garage podium (July 2023 – July 2027), Phase II –
Towers 3 and 4 with garage podium (July 2027 – July 2031), and Phase III – Tower 5 (post July 2031). Phases 1-3 would
start on the south side of the site (closer to Boeing) and would develop to the north side of the lot (closer to Gene Coulon
Memorial Beach Park). A fourth and final phase is being considered for a sixth tower with 130,000 square feet for office
and retail at the south corner of the development near the intersection of Park Ave N and 757th Ave NE. The phased
development could reach as high as 1.6 million gross square feet. The proposed nine-level development would be built
at the same height and scale as the existing Southport offices with an overall height of approximately 154 feet above
average grade. Parking for 2,207 vehicles would be provided in a shared 4- and 5-level parking garage and 57 spaces are
proposed as on-street parking. In addition, the applicant is proposing to work closely with PSE for the engineering and

capacity needs of the development in order to relocate the powerlines and utility switchgear adjacent to Johns Creek.
Vehicular access to Southport West would be provided by Park Ave N, Lake Washington Blvd N, and the addition of an
internal center road and frontage road.
The site is generally level and consists of gravel yard and asphalt, a Puget Sound Energy switchgear, and an
office/warehouse building. The site contains high seismic hazard areas and the northeast corner of the site contains
Johns Creek and regulated slopes. The soil consists of a loose to medium dense sand, underlain by soft to medium dense
silt, then medium dense to dense sand, very soft silt and clay, and finally dense to very dense silty sand. Groundwater
was observed in the historical exploration at Southport at depths ranging from 3 to 10 feet below existing grade.
Preliminary estimates of cut and fill include approximately 25,000 cubic yards of excavation and 39,200 cubic yards of fill
from an approved source. The depth of excavation is anticipated to not exceed approximately two feet (2’) below ground
level, except for building cores where excavation would be deeper. Stormwater runoff from pollution generating surfaces
would be captured by catch basins and treated in cartridge filter facilities prior to connection into three (3) existing
drainage systems. No significant trees are proposed to be removed. Southport is proposing to plant 115 new trees along
with a variety of shrubs and perennials. The applicant has submitted a Preliminary Geotechnical Report, Technical
Information Report, Traffic Impact Analysis, and Stream Assessment and Final Mitigation Plan with the application.

capacity needs of the development in order to relocate the powerlines and utility switchgear adjacent to Johns Creek.
Vehicular access to Southport West would be provided by Park Ave N, Lake Washington Blvd N, and the addition of an
internal center road and frontage road.
The site is generally level and consists of gravel yard and asphalt, a Puget Sound Energy switchgear, and an
office/warehouse building. The site contains high seismic hazard areas and the northeast corner of the site contains
Johns Creek and regulated slopes. The soil consists of a loose to medium dense sand, underlain by soft to medium dense
silt, then medium dense to dense sand, very soft silt and clay, and finally dense to very dense silty sand. Groundwater
was observed in the historical exploration at Southport at depths ranging from 3 to 10 feet below existing grade.
Preliminary estimates of cut and fill include approximately 25,000 cubic yards of excavation and 39,200 cubic yards of fill
from an approved source. The depth of excavation is anticipated to not exceed approximately two feet (2’) below ground
level, except for building cores where excavation would be deeper. Stormwater runoff from pollution generating surfaces
would be captured by catch basins and treated in cartridge filter facilities prior to connection into three (3) existing
drainage systems. No significant trees are proposed to be removed. Southport is proposing to plant 115 new trees along
with a variety of shrubs and perennials. The applicant has submitted a Preliminary Geotechnical Report, Technical
Information Report, Traffic Impact Analysis, and Stream Assessment and Final Mitigation Plan with the application.

PROJECT DESCRIPTION: The applicant, Southport West LLC, is requesting Master Plan Review, Hearing Examiner
Site Plan Review and Environmental (SEPA) Review for the construction of Southport West. Southport West is the
completion of the southerly portion of the Southport Development located at the south end of Lake Washington Blvd N.
The proposed expansion of Southport would be located on the 10.09-acre former Puget Sound Energy (PSE) Substation
and PSE utility parcels (APNs 082305-9191 and -9178). The two (2) parcels are located in the Urban Center-2 (UC-2) zone
and the Urban Design District ‘C’. The site is proposed to be developed as five (5) high-rise buildings with approximately
1,200,000 square feet of office and 50,000 of retail development in multiple phases. The proposed first three phases
would be developed as follows: Phase I – Towers 1 and 2 with the garage podium (July 2023 – July 2027), Phase II –
Towers 3 and 4 with garage podium (July 2027 – July 2031), and Phase III – Tower 5 (post July 2031). Phases 1-3 would
start on the south side of the site (closer to Boeing) and would develop to the north side of the lot (closer to Gene Coulon
Memorial Beach Park). A fourth and final phase is being considered for a sixth tower with 130,000 square feet for office
and retail at the south corner of the development near the intersection of Park Ave N and 757th Ave NE. The phased
development could reach as high as 1.6 million gross square feet. The proposed nine-level development would be built
at the same height and scale as the existing Southport offices with an overall height of approximately 154 feet above
average grade. Parking for 2,207 vehicles would be provided in a shared 4- and 5-level parking garage and 57 spaces are
proposed as on-street parking. In addition, the applicant is proposing to work closely with PSE for the engineering and

PROJECT DESCRIPTION: The applicant, Southport West LLC, is requesting Master Plan Review, Hearing Examiner
Site Plan Review and Environmental (SEPA) Review for the construction of Southport West. Southport West is the
completion of the southerly portion of the Southport Development located at the south end of Lake Washington Blvd N.
The proposed expansion of Southport would be located on the 10.09-acre former Puget Sound Energy (PSE) Substation
and PSE utility parcels (APNs 082305-9191 and -9178). The two (2) parcels are located in the Urban Center-2 (UC-2) zone
and the Urban Design District ‘C’. The site is proposed to be developed as five (5) high-rise buildings with approximately
1,200,000 square feet of office and 50,000 of retail development in multiple phases. The proposed first three phases
would be developed as follows: Phase I – Towers 1 and 2 with the garage podium (July 2023 – July 2027), Phase II –
Towers 3 and 4 with garage podium (July 2027 – July 2031), and Phase III – Tower 5 (post July 2031). Phases 1-3 would
start on the south side of the site (closer to Boeing) and would develop to the north side of the lot (closer to Gene Coulon
Memorial Beach Park). A fourth and final phase is being considered for a sixth tower with 130,000 square feet for office
and retail at the south corner of the development near the intersection of Park Ave N and 757th Ave NE. The phased
development could reach as high as 1.6 million gross square feet. The proposed nine-level development would be built
at the same height and scale as the existing Southport offices with an overall height of approximately 154 feet above
average grade. Parking for 2,207 vehicles would be provided in a shared 4- and 5-level parking garage and 57 spaces are
proposed as on-street parking. In addition, the applicant is proposing to work closely with PSE for the engineering and

capacity needs of the development in order to relocate the powerlines and utility switchgear adjacent to Johns Creek.
Vehicular access to Southport West would be provided by Park Ave N, Lake Washington Blvd N, and the addition of an
internal center road and frontage road.
The site is generally level and consists of gravel yard and asphalt, a Puget Sound Energy switchgear, and an
office/warehouse building. The site contains high seismic hazard areas and the northeast corner of the site contains
Johns Creek and regulated slopes. The soil consists of a loose to medium dense sand, underlain by soft to medium dense
silt, then medium dense to dense sand, very soft silt and clay, and finally dense to very dense silty sand. Groundwater
was observed in the historical exploration at Southport at depths ranging from 3 to 10 feet below existing grade.
Preliminary estimates of cut and fill include approximately 25,000 cubic yards of excavation and 39,200 cubic yards of fill
from an approved source. The depth of excavation is anticipated to not exceed approximately two feet (2’) below ground
level, except for building cores where excavation would be deeper. Stormwater runoff from pollution generating surfaces
would be captured by catch basins and treated in cartridge filter facilities prior to connection into three (3) existing
drainage systems. No significant trees are proposed to be removed. Southport is proposing to plant 115 new trees along
with a variety of shrubs and perennials. The applicant has submitted a Preliminary Geotechnical Report, Technical
Information Report, Traffic Impact Analysis, and Stream Assessment and Final Mitigation Plan with the application.

and retail at the south corner of the development near the intersection of Park Ave N and 757th Ave NE. The phased
development could reach as high as 1.6 million gross square feet. The proposed nine-level development would be built
at the same height and scale as the existing Southport offices with an overall height of approximately 154 feet above
average grade. Parking for 2,207 vehicles would be provided in a shared 4- and 5-level parking garage and 57 spaces are
proposed as on-street parking. In addition, the applicant is proposing to work closely with PSE for the engineering and

Vehicular access to Southport West would be provided by Park Ave N, Lake Washington Blvd N, and the addition of an
internal center road and frontage road.
The site is generally level and consists of gravel yard and asphalt, a Puget Sound Energy switchgear, and an
office/warehouse building. The site contains high seismic hazard areas and the northeast corner of the site contains
Johns Creek and regulated slopes. The soil consists of a loose to medium dense sand, underlain by soft to medium dense
silt, then medium dense to dense sand, very soft silt and clay, and finally dense to very dense silty sand. Groundwater
was observed in the historical exploration at Southport at depths ranging from 3 to 10 feet below existing grade.
Preliminary estimates of cut and fill include approximately 25,000 cubic yards of excavation and 39,200 cubic yards of fill
from an approved source. The depth of excavation is anticipated to not exceed approximately two feet (2’) below ground
level, except for building cores where excavation would be deeper. Stormwater runoff from pollution generating surfaces
would be captured by catch basins and treated in cartridge filter facilities prior to connection into three (3) existing
drainage systems. No significant trees are proposed to be removed. Southport is proposing to plant 115 new trees along
with a variety of shrubs and perennials. The applicant has submitted a Preliminary Geotechnical Report, Technical
Information Report, Traffic Impact Analysis, and Stream Assessment and Final Mitigation Plan with the application.

PROJECT DESCRIPTION: The applicant, Southport West LLC, is requesting Master Plan Review, Hearing Examiner
Site Plan Review and Environmental (SEPA) Review for the construction of Southport West. Southport West is the
completion of the southerly portion of the Southport Development located at the south end of Lake Washington Blvd N.
The proposed expansion of Southport would be located on the 10.09-acre former Puget Sound Energy (PSE) Substation
and PSE utility parcels (APNs 082305-9191 and -9178). The two (2) parcels are located in the Urban Center-2 (UC-2) zone
and the Urban Design District ‘C’. The site is proposed to be developed as five (5) high-rise buildings with approximately
1,200,000 square feet of office and 50,000 of retail development in multiple phases. The proposed first three phases
would be developed as follows: Phase I – Towers 1 and 2 with the garage podium (July 2023 – July 2027), Phase II –
Towers 3 and 4 with garage podium (July 2027 – July 2031), and Phase III – Tower 5 (post July 2031). Phases 1-3 would
start on the south side of the site (closer to Boeing) and would develop to the north side of the lot (closer to Gene Coulon
Memorial Beach Park). A fourth and final phase is being considered for a sixth tower with 130,000 square feet for office
and retail at the south corner of the development near the intersection of Park Ave N and 757th Ave NE. The phased
development could reach as high as 1.6 million gross square feet. The proposed nine-level development would be built
at the same height and scale as the existing Southport offices with an overall height of approximately 154 feet above
average grade. Parking for 2,207 vehicles would be provided in a shared 4- and 5-level parking garage and 57 spaces are
proposed as on-street parking. In addition, the applicant is proposing to work closely with PSE for the engineering and

capacity needs of the development in order to relocate the powerlines and utility switchgear adjacent to Johns Creek.
Vehicular access to Southport West would be provided by Park Ave N, Lake Washington Blvd N, and the addition of an
internal center road and frontage road.
The site is generally level and consists of gravel yard and asphalt, a Puget Sound Energy switchgear, and an
office/warehouse building. The site contains high seismic hazard areas and the northeast corner of the site contains
Johns Creek and regulated slopes. The soil consists of a loose to medium dense sand, underlain by soft to medium dense
silt, then medium dense to dense sand, very soft silt and clay, and finally dense to very dense silty sand. Groundwater
was observed in the historical exploration at Southport at depths ranging from 3 to 10 feet below existing grade.
Preliminary estimates of cut and fill include approximately 25,000 cubic yards of excavation and 39,200 cubic yards of fill
from an approved source. The depth of excavation is anticipated to not exceed approximately two feet (2’) below ground
level, except for building cores where excavation would be deeper. Stormwater runoff from pollution generating surfaces
would be captured by catch basins and treated in cartridge filter facilities prior to connection into three (3) existing
drainage systems. No significant trees are proposed to be removed. Southport is proposing to plant 115 new trees along
with a variety of shrubs and perennials. The applicant has submitted a Preliminary Geotechnical Report, Technical
Information Report, Traffic Impact Analysis, and Stream Assessment and Final Mitigation Plan with the application.

PROJECT DESCRIPTION: The applicant, Southport West LLC, is requesting Master Plan Review, Hearing Examiner
Site Plan Review and Environmental (SEPA) Review for the construction of Southport West. Southport West is the
completion of the southerly portion of the Southport Development located at the south end of Lake Washington Blvd N.
The proposed expansion of Southport would be located on the 10.09-acre former Puget Sound Energy (PSE) Substation
and PSE utility parcels (APNs 082305-9191 and -9178). The two (2) parcels are located in the Urban Center-2 (UC-2) zone
and the Urban Design District ‘C’. The site is proposed to be developed as five (5) high-rise buildings with approximately
1,200,000 square feet of office and 50,000 of retail development in multiple phases. The proposed first three phases
would be developed as follows: Phase I – Towers 1 and 2 with the garage podium (July 2023 – July 2027), Phase II –
Towers 3 and 4 with garage podium (July 2027 – July 2031), and Phase III – Tower 5 (post July 2031). Phases 1-3 would
start on the south side of the site (closer to Boeing) and would develop to the north side of the lot (closer to Gene Coulon
Memorial Beach Park). A fourth and final phase is being considered for a sixth tower with 130,000 square feet for office
and retail at the south corner of the development near the intersection of Park Ave N and 757th Ave NE. The phased
development could reach as high as 1.6 million gross square feet. The proposed nine-level development would be built
at the same height and scale as the existing Southport offices with an overall height of approximately 154 feet above
average grade. Parking for 2,207 vehicles would be provided in a shared 4- and 5-level parking garage and 57 spaces are
proposed as on-street parking. In addition, the applicant is proposing to work closely with PSE for the engineering and

capacity needs of the development in order to relocate the powerlines and utility switchgear adjacent to Johns Creek.
Vehicular access to Southport West would be provided by Park Ave N, Lake Washington Blvd N, and the addition of an
internal center road and frontage road.
The site is generally level and consists of gravel yard and asphalt, a Puget Sound Energy switchgear, and an
office/warehouse building. The site contains high seismic hazard areas and the northeast corner of the site contains
Johns Creek and regulated slopes. The soil consists of a loose to medium dense sand, underlain by soft to medium dense
silt, then medium dense to dense sand, very soft silt and clay, and finally dense to very dense silty sand. Groundwater
was observed in the historical exploration at Southport at depths ranging from 3 to 10 feet below existing grade.
Preliminary estimates of cut and fill include approximately 25,000 cubic yards of excavation and 39,200 cubic yards of fill
from an approved source. The depth of excavation is anticipated to not exceed approximately two feet (2’) below ground
level, except for building cores where excavation would be deeper. Stormwater runoff from pollution generating surfaces
would be captured by catch basins and treated in cartridge filter facilities prior to connection into three (3) existing
drainage systems. No significant trees are proposed to be removed. Southport is proposing to plant 115 new trees along
with a variety of shrubs and perennials. The applicant has submitted a Preliminary Geotechnical Report, Technical
Information Report, Traffic Impact Analysis, and Stream Assessment and Final Mitigation Plan with the application.

office/warehouse building. The site contains high seismic hazard areas and the northeast corner of the site contains
Johns Creek and regulated slopes. The soil consists of a loose to medium dense sand, underlain by soft to medium dense
silt, then medium dense to dense sand, very soft silt and clay, and finally dense to very dense silty sand. Groundwater
was observed in the historical exploration at Southport at depths ranging from 3 to 10 feet below existing grade.
Preliminary estimates of cut and fill include approximately 25,000 cubic yards of excavation and 39,200 cubic yards of fill
from an approved source. The depth of excavation is anticipated to not exceed approximately two feet (2’) below ground
level, except for building cores where excavation would be deeper. Stormwater runoff from pollution generating surfaces
would be captured by catch basins and treated in cartridge filter facilities prior to connection into three (3) existing
drainage systems. No significant trees are proposed to be removed. Southport is proposing to plant 115 new trees along
with a variety of shrubs and perennials. The applicant has submitted a Preliminary Geotechnical Report, Technical
Information Report, Traffic Impact Analysis, and Stream Assessment and Final Mitigation Plan with the application.

Site Plan Review and Environmental (SEPA) Review for the construction of Southport West. Southport West is the
completion of the southerly portion of the Southport Development located at the south end of Lake Washington Blvd N.
The proposed expansion of Southport would be located on the 10.09-acre former Puget Sound Energy (PSE) Substation
and PSE utility parcels (APNs 082305-9191 and -9178). The two (2) parcels are located in the Urban Center-2 (UC-2) zone
and the Urban Design District ‘C’. The site is proposed to be developed as five (5) high-rise buildings with approximately
1,200,000 square feet of office and 50,000 of retail development in multiple phases. The proposed first three phases
would be developed as follows: Phase I – Towers 1 and 2 with the garage podium (July 2023 – July 2027), Phase II –
Towers 3 and 4 with garage podium (July 2027 – July 2031), and Phase III – Tower 5 (post July 2031). Phases 1-3 would
start on the south side of the site (closer to Boeing) and would develop to the north side of the lot (closer to Gene Coulon
Memorial Beach Park). A fourth and final phase is being considered for a sixth tower with 130,000 square feet for office
and retail at the south corner of the development near the intersection of Park Ave N and 757th Ave NE. The phased
development could reach as high as 1.6 million gross square feet. The proposed nine-level development would be built
at the same height and scale as the existing Southport offices with an overall height of approximately 154 feet above
average grade. Parking for 2,207 vehicles would be provided in a shared 4- and 5-level parking garage and 57 spaces are
proposed as on-street parking. In addition, the applicant is proposing to work closely with PSE for the engineering and

PROJECT DESCRIPTION: The applicant, Southport West LLC, is requesting Master Plan Review, Hearing Examiner
Site Plan Review and Environmental (SEPA) Review for the construction of Southport West. Southport West is the
completion of the southerly portion of the Southport Development located at the south end of Lake Washington Blvd N.
The proposed expansion of Southport would be located on the 10.09-acre former Puget Sound Energy (PSE) Substation
and PSE utility parcels (APNs 082305-9191 and -9178). The two (2) parcels are located in the Urban Center-2 (UC-2) zone
and the Urban Design District ‘C’. The site is proposed to be developed as five (5) high-rise buildings with approximately
1,200,000 square feet of office and 50,000 of retail development in multiple phases. The proposed first three phases
would be developed as follows: Phase I – Towers 1 and 2 with the garage podium (July 2023 – July 2027), Phase II –
Towers 3 and 4 with garage podium (July 2027 – July 2031), and Phase III – Tower 5 (post July 2031). Phases 1-3 would
start on the south side of the site (closer to Boeing) and would develop to the north side of the lot (closer to Gene Coulon
Memorial Beach Park). A fourth and final phase is being considered for a sixth tower with 130,000 square feet for office
and retail at the south corner of the development near the intersection of Park Ave N and 757th Ave NE. The phased
development could reach as high as 1.6 million gross square feet. The proposed nine-level development would be built
at the same height and scale as the existing Southport offices with an overall height of approximately 154 feet above
average grade. Parking for 2,207 vehicles would be provided in a shared 4- and 5-level parking garage and 57 spaces are
proposed as on-street parking. In addition, the applicant is proposing to work closely with PSE for the engineering and

capacity needs of the development in order to relocate the powerlines and utility switchgear adjacent to Johns Creek.
Vehicular access to Southport West would be provided by Park Ave N, Lake Washington Blvd N, and the addition of an
internal center road and frontage road.
The site is generally level and consists of gravel yard and asphalt, a Puget Sound Energy switchgear, and an
office/warehouse building. The site contains high seismic hazard areas and the northeast corner of the site contains
Johns Creek and regulated slopes. The soil consists of a loose to medium dense sand, underlain by soft to medium dense
silt, then medium dense to dense sand, very soft silt and clay, and finally dense to very dense silty sand. Groundwater
was observed in the historical exploration at Southport at depths ranging from 3 to 10 feet below existing grade.
Preliminary estimates of cut and fill include approximately 25,000 cubic yards of excavation and 39,200 cubic yards of fill
from an approved source. The depth of excavation is anticipated to not exceed approximately two feet (2’) below ground
level, except for building cores where excavation would be deeper. Stormwater runoff from pollution generating surfaces
would be captured by catch basins and treated in cartridge filter facilities prior to connection into three (3) existing
drainage systems. No significant trees are proposed to be removed. Southport is proposing to plant 115 new trees along
with a variety of shrubs and perennials. The applicant has submitted a Preliminary Geotechnical Report, Technical
Information Report, Traffic Impact Analysis, and Stream Assessment and Final Mitigation Plan with the application.

capacity needs of the development in order to relocate the powerlines and utility switchgear adjacent to Johns Creek.
Vehicular access to Southport West would be provided by Park Ave N, Lake Washington Blvd N, and the addition of an
internal center road and frontage road.
The site is generally level and consists of gravel yard and asphalt, a Puget Sound Energy switchgear, and an
office/warehouse building. The site contains high seismic hazard areas and the northeast corner of the site contains
Johns Creek and regulated slopes. The soil consists of a loose to medium dense sand, underlain by soft to medium dense
silt, then medium dense to dense sand, very soft silt and clay, and finally dense to very dense silty sand. Groundwater
was observed in the historical exploration at Southport at depths ranging from 3 to 10 feet below existing grade.
Preliminary estimates of cut and fill include approximately 25,000 cubic yards of excavation and 39,200 cubic yards of fill
from an approved source. The depth of excavation is anticipated to not exceed approximately two feet (2’) below ground
level, except for building cores where excavation would be deeper. Stormwater runoff from pollution generating surfaces
would be captured by catch basins and treated in cartridge filter facilities prior to connection into three (3) existing
drainage systems. No significant trees are proposed to be removed. Southport is proposing to plant 115 new trees along
with a variety of shrubs and perennials. The applicant has submitted a Preliminary Geotechnical Report, Technical
Information Report, Traffic Impact Analysis, and Stream Assessment and Final Mitigation Plan with the application.

The proposed expansion of Southport would be located on the 10.09-acre former Puget Sound Energy (PSE) Substation
and PSE utility parcels (APNs 082305-9191 and -9178). The two (2) parcels are located in the Urban Center-2 (UC-2) zone
and the Urban Design District ‘C’. The site is proposed to be developed as five (5) high-rise buildings with approximately
1,200,000 square feet of office and 50,000 of retail development in multiple phases. The proposed first three phases
would be developed as follows: Phase I – Towers 1 and 2 with the garage podium (July 2023 – July 2027), Phase II –
Towers 3 and 4 with garage podium (July 2027 – July 2031), and Phase III – Tower 5 (post July 2031). Phases 1-3 would
start on the south side of the site (closer to Boeing) and would develop to the north side of the lot (closer to Gene Coulon
Memorial Beach Park). A fourth and final phase is being considered for a sixth tower with 130,000 square feet for office
and retail at the south corner of the development near the intersection of Park Ave N and 757th Ave NE. The phased
development could reach as high as 1.6 million gross square feet. The proposed nine-level development would be built
at the same height and scale as the existing Southport offices with an overall height of approximately 154 feet above
average grade. Parking for 2,207 vehicles would be provided in a shared 4- and 5-level parking garage and 57 spaces are

PROJECT DESCRIPTION: The applicant, Southport West LLC, is requesting Master Plan Review, Hearing Examiner
Site Plan Review and Environmental (SEPA) Review for the construction of Southport West. Southport West is the
completion of the southerly portion of the Southport Development located at the south end of Lake Washington Blvd N.
The proposed expansion of Southport would be located on the 10.09-acre former Puget Sound Energy (PSE) Substation
and PSE utility parcels (APNs 082305-9191 and -9178). The two (2) parcels are located in the Urban Center-2 (UC-2) zone
and the Urban Design District ‘C’. The site is proposed to be developed as five (5) high-rise buildings with approximately
1,200,000 square feet of office and 50,000 of retail development in multiple phases. The proposed first three phases
would be developed as follows: Phase I – Towers 1 and 2 with the garage podium (July 2023 – July 2027), Phase II –
Towers 3 and 4 with garage podium (July 2027 – July 2031), and Phase III – Tower 5 (post July 2031). Phases 1-3 would
start on the south side of the site (closer to Boeing) and would develop to the north side of the lot (closer to Gene Coulon
Memorial Beach Park). A fourth and final phase is being considered for a sixth tower with 130,000 square feet for office
and retail at the south corner of the development near the intersection of Park Ave N and 757th Ave NE. The phased
development could reach as high as 1.6 million gross square feet. The proposed nine-level development would be built
at the same height and scale as the existing Southport offices with an overall height of approximately 154 feet above
average grade. Parking for 2,207 vehicles would be provided in a shared 4- and 5-level parking garage and 57 spaces are
proposed as on-street parking. In addition, the applicant is proposing to work closely with PSE for the engineering and

capacity needs of the development in order to relocate the powerlines and utility switchgear adjacent to Johns Creek.
Vehicular access to Southport West would be provided by Park Ave N, Lake Washington Blvd N, and the addition of an
internal center road and frontage road.
The site is generally level and consists of gravel yard and asphalt, a Puget Sound Energy switchgear, and an
office/warehouse building. The site contains high seismic hazard areas and the northeast corner of the site contains
Johns Creek and regulated slopes. The soil consists of a loose to medium dense sand, underlain by soft to medium dense
silt, then medium dense to dense sand, very soft silt and clay, and finally dense to very dense silty sand. Groundwater
was observed in the historical exploration at Southport at depths ranging from 3 to 10 feet below existing grade.
Preliminary estimates of cut and fill include approximately 25,000 cubic yards of excavation and 39,200 cubic yards of fill
from an approved source. The depth of excavation is anticipated to not exceed approximately two feet (2’) below ground
level, except for building cores where excavation would be deeper. Stormwater runoff from pollution generating surfaces
would be captured by catch basins and treated in cartridge filter facilities prior to connection into three (3) existing
drainage systems. No significant trees are proposed to be removed. Southport is proposing to plant 115 new trees along
with a variety of shrubs and perennials. The applicant has submitted a Preliminary Geotechnical Report, Technical
Information Report, Traffic Impact Analysis, and Stream Assessment and Final Mitigation Plan with the application.

and PSE utility parcels (APNs 082305-9191 and -9178). The two (2) parcels are located in the Urban Center-2 (UC-2) zone
and the Urban Design District ‘C’. The site is proposed to be developed as five (5) high-rise buildings with approximately
1,200,000 square feet of office and 50,000 of retail development in multiple phases. The proposed first three phases
would be developed as follows: Phase I – Towers 1 and 2 with the garage podium (July 2023 – July 2027), Phase II –
Towers 3 and 4 with garage podium (July 2027 – July 2031), and Phase III – Tower 5 (post July 2031). Phases 1-3 would
start on the south side of the site (closer to Boeing) and would develop to the north side of the lot (closer to Gene Coulon
Memorial Beach Park). A fourth and final phase is being considered for a sixth tower with 130,000 square feet for office
and retail at the south corner of the development near the intersection of Park Ave N and 757th Ave NE. The phased
development could reach as high as 1.6 million gross square feet. The proposed nine-level development would be built
at the same height and scale as the existing Southport offices with an overall height of approximately 154 feet above
average grade. Parking for 2,207 vehicles would be provided in a shared 4- and 5-level parking garage and 57 spaces are
proposed as on-street parking. In addition, the applicant is proposing to work closely with PSE for the engineering and

capacity needs of the development in order to relocate the powerlines and utility switchgear adjacent to Johns Creek.
Vehicular access to Southport West would be provided by Park Ave N, Lake Washington Blvd N, and the addition of an
internal center road and frontage road.
The site is generally level and consists of gravel yard and asphalt, a Puget Sound Energy switchgear, and an
office/warehouse building. The site contains high seismic hazard areas and the northeast corner of the site contains
Johns Creek and regulated slopes. The soil consists of a loose to medium dense sand, underlain by soft to medium dense
silt, then medium dense to dense sand, very soft silt and clay, and finally dense to very dense silty sand. Groundwater
was observed in the historical exploration at Southport at depths ranging from 3 to 10 feet below existing grade.
Preliminary estimates of cut and fill include approximately 25,000 cubic yards of excavation and 39,200 cubic yards of fill
from an approved source. The depth of excavation is anticipated to not exceed approximately two feet (2’) below ground
level, except for building cores where excavation would be deeper. Stormwater runoff from pollution generating surfaces
would be captured by catch basins and treated in cartridge filter facilities prior to connection into three (3) existing
drainage systems. No significant trees are proposed to be removed. Southport is proposing to plant 115 new trees along
with a variety of shrubs and perennials. The applicant has submitted a Preliminary Geotechnical Report, Technical
Information Report, Traffic Impact Analysis, and Stream Assessment and Final Mitigation Plan with the application.

PROJECT DESCRIPTION: The applicant, Southport West LLC, is requesting Master Plan Review, Hearing Examiner
Site Plan Review and Environmental (SEPA) Review for the construction of Southport West. Southport West is the
completion of the southerly portion of the Southport Development located at the south end of Lake Washington Blvd N.
The proposed expansion of Southport would be located on the 10.09-acre former Puget Sound Energy (PSE) Substation
and PSE utility parcels (APNs 082305-9191 and -9178). The two (2) parcels are located in the Urban Center-2 (UC-2) zone
and the Urban Design District ‘C’. The site is proposed to be developed as five (5) high-rise buildings with approximately
1,200,000 square feet of office and 50,000 of retail development in multiple phases. The proposed first three phases
would be developed as follows: Phase I – Towers 1 and 2 with the garage podium (July 2023 – July 2027), Phase II –
Towers 3 and 4 with garage podium (July 2027 – July 2031), and Phase III – Tower 5 (post July 2031). Phases 1-3 would
start on the south side of the site (closer to Boeing) and would develop to the north side of the lot (closer to Gene Coulon
Memorial Beach Park). A fourth and final phase is being considered for a sixth tower with 130,000 square feet for office
and retail at the south corner of the development near the intersection of Park Ave N and 757th Ave NE. The phased
development could reach as high as 1.6 million gross square feet. The proposed nine-level development would be built
at the same height and scale as the existing Southport offices with an overall height of approximately 154 feet above
average grade. Parking for 2,207 vehicles would be provided in a shared 4- and 5-level parking garage and 57 spaces are
proposed as on-street parking. In addition, the applicant is proposing to work closely with PSE for the engineering and

Vehicular access to Southport West would be provided by Park Ave N, Lake Washington Blvd N, and the addition of an
internal center road and frontage road.
The site is generally level and consists of gravel yard and asphalt, a Puget Sound Energy switchgear, and an
office/warehouse building. The site contains high seismic hazard areas and the northeast corner of the site contains
Johns Creek and regulated slopes. The soil consists of a loose to medium dense sand, underlain by soft to medium dense
silt, then medium dense to dense sand, very soft silt and clay, and finally dense to very dense silty sand. Groundwater
was observed in the historical exploration at Southport at depths ranging from 3 to 10 feet below existing grade.
Preliminary estimates of cut and fill include approximately 25,000 cubic yards of excavation and 39,200 cubic yards of fill
from an approved source. The depth of excavation is anticipated to not exceed approximately two feet (2’) below ground
level, except for building cores where excavation would be deeper. Stormwater runoff from pollution generating surfaces
would be captured by catch basins and treated in cartridge filter facilities prior to connection into three (3) existing
drainage systems. No significant trees are proposed to be removed. Southport is proposing to plant 115 new trees along
with a variety of shrubs and perennials. The applicant has submitted a Preliminary Geotechnical Report, Technical
Information Report, Traffic Impact Analysis, and Stream Assessment and Final Mitigation Plan with the application.

PROJECT DESCRIPTION: The applicant, Southport West LLC, is requesting Master Plan Review, Hearing Examiner
Site Plan Review and Environmental (SEPA) Review for the construction of Southport West. Southport West is the
completion of the southerly portion of the Southport Development located at the south end of Lake Washington Blvd N.
The proposed expansion of Southport would be located on the 10.09-acre former Puget Sound Energy (PSE) Substation
and PSE utility parcels (APNs 082305-9191 and -9178). The two (2) parcels are located in the Urban Center-2 (UC-2) zone
and the Urban Design District ‘C’. The site is proposed to be developed as five (5) high-rise buildings with approximately
1,200,000 square feet of office and 50,000 of retail development in multiple phases. The proposed first three phases
would be developed as follows: Phase I – Towers 1 and 2 with the garage podium (July 2023 – July 2027), Phase II –
Towers 3 and 4 with garage podium (July 2027 – July 2031), and Phase III – Tower 5 (post July 2031). Phases 1-3 would
start on the south side of the site (closer to Boeing) and would develop to the north side of the lot (closer to Gene Coulon
Memorial Beach Park). A fourth and final phase is being considered for a sixth tower with 130,000 square feet for office
and retail at the south corner of the development near the intersection of Park Ave N and 757th Ave NE. The phased
development could reach as high as 1.6 million gross square feet. The proposed nine-level development would be built
at the same height and scale as the existing Southport offices with an overall height of approximately 154 feet above
average grade. Parking for 2,207 vehicles would be provided in a shared 4- and 5-level parking garage and 57 spaces are
proposed as on-street parking. In addition, the applicant is proposing to work closely with PSE for the engineering and

capacity needs of the development in order to relocate the powerlines and utility switchgear adjacent to Johns Creek.
Vehicular access to Southport West would be provided by Park Ave N, Lake Washington Blvd N, and the addition of an
internal center road and frontage road.
The site is generally level and consists of gravel yard and asphalt, a Puget Sound Energy switchgear, and an
office/warehouse building. The site contains high seismic hazard areas and the northeast corner of the site contains
Johns Creek and regulated slopes. The soil consists of a loose to medium dense sand, underlain by soft to medium dense
silt, then medium dense to dense sand, very soft silt and clay, and finally dense to very dense silty sand. Groundwater
was observed in the historical exploration at Southport at depths ranging from 3 to 10 feet below existing grade.
Preliminary estimates of cut and fill include approximately 25,000 cubic yards of excavation and 39,200 cubic yards of fill
from an approved source. The depth of excavation is anticipated to not exceed approximately two feet (2’) below ground
level, except for building cores where excavation would be deeper. Stormwater runoff from pollution generating surfaces
would be captured by catch basins and treated in cartridge filter facilities prior to connection into three (3) existing
drainage systems. No significant trees are proposed to be removed. Southport is proposing to plant 115 new trees along
with a variety of shrubs and perennials. The applicant has submitted a Preliminary Geotechnical Report, Technical
Information Report, Traffic Impact Analysis, and Stream Assessment and Final Mitigation Plan with the application.

capacity needs of the development in order to relocate the powerlines and utility switchgear adjacent to Johns Creek.
Vehicular access to Southport West would be provided by Park Ave N, Lake Washington Blvd N, and the addition of an
internal center road and frontage road.
The site is generally level and consists of gravel yard and asphalt, a Puget Sound Energy switchgear, and an
office/warehouse building. The site contains high seismic hazard areas and the northeast corner of the site contains
Johns Creek and regulated slopes. The soil consists of a loose to medium dense sand, underlain by soft to medium dense
silt, then medium dense to dense sand, very soft silt and clay, and finally dense to very dense silty sand. Groundwater
was observed in the historical exploration at Southport at depths ranging from 3 to 10 feet below existing grade.
Preliminary estimates of cut and fill include approximately 25,000 cubic yards of excavation and 39,200 cubic yards of fill
from an approved source. The depth of excavation is anticipated to not exceed approximately two feet (2’) below ground
level, except for building cores where excavation would be deeper. Stormwater runoff from pollution generating surfaces
would be captured by catch basins and treated in cartridge filter facilities prior to connection into three (3) existing
drainage systems. No significant trees are proposed to be removed. Southport is proposing to plant 115 new trees along
with a variety of shrubs and perennials. The applicant has submitted a Preliminary Geotechnical Report, Technical
Information Report, Traffic Impact Analysis, and Stream Assessment and Final Mitigation Plan with the application.

Site Plan Review and Environmental (SEPA) Review for the construction of Southport West. Southport West is the
completion of the southerly portion of the Southport Development located at the south end of Lake Washington Blvd N.
The proposed expansion of Southport would be located on the 10.09-acre former Puget Sound Energy (PSE) Substation
and PSE utility parcels (APNs 082305-9191 and -9178). The two (2) parcels are located in the Urban Center-2 (UC-2) zone
and the Urban Design District ‘C’. The site is proposed to be developed as five (5) high-rise buildings with approximately
1,200,000 square feet of office and 50,000 of retail development in multiple phases. The proposed first three phases
would be developed as follows: Phase I – Towers 1 and 2 with the garage podium (July 2023 – July 2027), Phase II –
Towers 3 and 4 with garage podium (July 2027 – July 2031), and Phase III – Tower 5 (post July 2031). Phases 1-3 would
start on the south side of the site (closer to Boeing) and would develop to the north side of the lot (closer to Gene Coulon
Memorial Beach Park). A fourth and final phase is being considered for a sixth tower with 130,000 square feet for office
and retail at the south corner of the development near the intersection of Park Ave N and 757th Ave NE. The phased
development could reach as high as 1.6 million gross square feet. The proposed nine-level development would be built
at the same height and scale as the existing Southport offices with an overall height of approximately 154 feet above
average grade. Parking for 2,207 vehicles would be provided in a shared 4- and 5-level parking garage and 57 spaces are
proposed as on-street parking. In addition, the applicant is proposing to work closely with PSE for the engineering and

PROJECT DESCRIPTION: The applicant, Southport West LLC, is requesting Master Plan Review, Hearing Examiner
Site Plan Review and Environmental (SEPA) Review for the construction of Southport West. Southport West is the
completion of the southerly portion of the Southport Development located at the south end of Lake Washington Blvd N.
The proposed expansion of Southport would be located on the 10.09-acre former Puget Sound Energy (PSE) Substation
and PSE utility parcels (APNs 082305-9191 and -9178). The two (2) parcels are located in the Urban Center-2 (UC-2) zone
and the Urban Design District ‘C’. The site is proposed to be developed as five (5) high-rise buildings with approximately
1,200,000 square feet of office and 50,000 of retail development in multiple phases. The proposed first three phases
would be developed as follows: Phase I – Towers 1 and 2 with the garage podium (July 2023 – July 2027), Phase II –
Towers 3 and 4 with garage podium (July 2027 – July 2031), and Phase III – Tower 5 (post July 2031). Phases 1-3 would
start on the south side of the site (closer to Boeing) and would develop to the north side of the lot (closer to Gene Coulon
Memorial Beach Park). A fourth and final phase is being considered for a sixth tower with 130,000 square feet for office
and retail at the south corner of the development near the intersection of Park Ave N and 757th Ave NE. The phased
development could reach as high as 1.6 million gross square feet. The proposed nine-level development would be built
at the same height and scale as the existing Southport offices with an overall height of approximately 154 feet above
average grade. Parking for 2,207 vehicles would be provided in a shared 4- and 5-level parking garage and 57 spaces are
proposed as on-street parking. In addition, the applicant is proposing to work closely with PSE for the engineering and

capacity needs of the development in order to relocate the powerlines and utility switchgear adjacent to Johns Creek.
Vehicular access to Southport West would be provided by Park Ave N, Lake Washington Blvd N, and the addition of an
internal center road and frontage road.
The site is generally level and consists of gravel yard and asphalt, a Puget Sound Energy switchgear, and an
office/warehouse building. The site contains high seismic hazard areas and the northeast corner of the site contains
Johns Creek and regulated slopes. The soil consists of a loose to medium dense sand, underlain by soft to medium dense
silt, then medium dense to dense sand, very soft silt and clay, and finally dense to very dense silty sand. Groundwater
was observed in the historical exploration at Southport at depths ranging from 3 to 10 feet below existing grade.
Preliminary estimates of cut and fill include approximately 25,000 cubic yards of excavation and 39,200 cubic yards of fill
from an approved source. The depth of excavation is anticipated to not exceed approximately two feet (2’) below ground
level, except for building cores where excavation would be deeper. Stormwater runoff from pollution generating surfaces
would be captured by catch basins and treated in cartridge filter facilities prior to connection into three (3) existing
drainage systems. No significant trees are proposed to be removed. Southport is proposing to plant 115 new trees along
with a variety of shrubs and perennials. The applicant has submitted a Preliminary Geotechnical Report, Technical
Information Report, Traffic Impact Analysis, and Stream Assessment and Final Mitigation Plan with the application.

Vehicular access to Southport West would be provided by Park Ave N, Lake Washington Blvd N, and the addition of an
internal center road and frontage road.
The site is generally level and consists of gravel yard and asphalt, a Puget Sound Energy switchgear, and an
office/warehouse building. The site contains high seismic hazard areas and the northeast corner of the site contains
Johns Creek and regulated slopes. The soil consists of a loose to medium dense sand, underlain by soft to medium dense
silt, then medium dense to dense sand, very soft silt and clay, and finally dense to very dense silty sand. Groundwater
was observed in the historical exploration at Southport at depths ranging from 3 to 10 feet below existing grade.
Preliminary estimates of cut and fill include approximately 25,000 cubic yards of excavation and 39,200 cubic yards of fill
from an approved source. The depth of excavation is anticipated to not exceed approximately two feet (2’) below ground
level, except for building cores where excavation would be deeper. Stormwater runoff from pollution generating surfaces
would be captured by catch basins and treated in cartridge filter facilities prior to connection into three (3) existing
drainage systems. No significant trees are proposed to be removed. Southport is proposing to plant 115 new trees along
with a variety of shrubs and perennials. The applicant has submitted a Preliminary Geotechnical Report, Technical
Information Report, Traffic Impact Analysis, and Stream Assessment and Final Mitigation Plan with the application.

PROJECT DESCRIPTION: The applicant, Southport West LLC, is requesting Master Plan Review, Hearing Examiner
Site Plan Review and Environmental (SEPA) Review for the construction of Southport West. Southport West is the
completion of the southerly portion of the Southport Development located at the south end of Lake Washington Blvd N.
The proposed expansion of Southport would be located on the 10.09-acre former Puget Sound Energy (PSE) Substation
and PSE utility parcels (APNs 082305-9191 and -9178). The two (2) parcels are located in the Urban Center-2 (UC-2) zone
and the Urban Design District ‘C’. The site is proposed to be developed as five (5) high-rise buildings with approximately
1,200,000 square feet of office and 50,000 of retail development in multiple phases. The proposed first three phases
would be developed as follows: Phase I – Towers 1 and 2 with the garage podium (July 2023 – July 2027), Phase II –
Towers 3 and 4 with garage podium (July 2027 – July 2031), and Phase III – Tower 5 (post July 2031). Phases 1-3 would
start on the south side of the site (closer to Boeing) and would develop to the north side of the lot (closer to Gene Coulon
Memorial Beach Park). A fourth and final phase is being considered for a sixth tower with 130,000 square feet for office
and retail at the south corner of the development near the intersection of Park Ave N and 757th Ave NE. The phased
development could reach as high as 1.6 million gross square feet. The proposed nine-level development would be built
at the same height and scale as the existing Southport offices with an overall height of approximately 154 feet above
average grade. Parking for 2,207 vehicles would be provided in a shared 4- and 5-level parking garage and 57 spaces are
proposed as on-street parking. In addition, the applicant is proposing to work closely with PSE for the engineering and

capacity needs of the development in order to relocate the powerlines and utility switchgear adjacent to Johns Creek.
Vehicular access to Southport West would be provided by Park Ave N, Lake Washington Blvd N, and the addition of an
internal center road and frontage road.
The site is generally level and consists of gravel yard and asphalt, a Puget Sound Energy switchgear, and an
office/warehouse building. The site contains high seismic hazard areas and the northeast corner of the site contains
Johns Creek and regulated slopes. The soil consists of a loose to medium dense sand, underlain by soft to medium dense
silt, then medium dense to dense sand, very soft silt and clay, and finally dense to very dense silty sand. Groundwater
was observed in the historical exploration at Southport at depths ranging from 3 to 10 feet below existing grade.
Preliminary estimates of cut and fill include approximately 25,000 cubic yards of excavation and 39,200 cubic yards of fill
from an approved source. The depth of excavation is anticipated to not exceed approximately two feet (2’) below ground
level, except for building cores where excavation would be deeper. Stormwater runoff from pollution generating surfaces
would be captured by catch basins and treated in cartridge filter facilities prior to connection into three (3) existing
drainage systems. No significant trees are proposed to be removed. Southport is proposing to plant 115 new trees along
with a variety of shrubs and perennials. The applicant has submitted a Preliminary Geotechnical Report, Technical
Information Report, Traffic Impact Analysis, and Stream Assessment and Final Mitigation Plan with the application.

PROJECT DESCRIPTION: The applicant, Southport West LLC, is requesting Master Plan Review, Hearing Examiner
Site Plan Review and Environmental (SEPA) Review for the construction of Southport West. Southport West is the
completion of the southerly portion of the Southport Development located at the south end of Lake Washington Blvd N.
The proposed expansion of Southport would be located on the 10.09-acre former Puget Sound Energy (PSE) Substation
and PSE utility parcels (APNs 082305-9191 and -9178). The two (2) parcels are located in the Urban Center-2 (UC-2) zone
and the Urban Design District ‘C’. The site is proposed to be developed as five (5) high-rise buildings with approximately
1,200,000 square feet of office and 50,000 of retail development in multiple phases. The proposed first three phases
would be developed as follows: Phase I – Towers 1 and 2 with the garage podium (July 2023 – July 2027), Phase II –
Towers 3 and 4 with garage podium (July 2027 – July 2031), and Phase III – Tower 5 (post July 2031). Phases 1-3 would
start on the south side of the site (closer to Boeing) and would develop to the north side of the lot (closer to Gene Coulon
Memorial Beach Park). A fourth and final phase is being considered for a sixth tower with 130,000 square feet for office
and retail at the south corner of the development near the intersection of Park Ave N and 757th Ave NE. The phased
development could reach as high as 1.6 million gross square feet. The proposed nine-level development would be built
at the same height and scale as the existing Southport offices with an overall height of approximately 154 feet above
average grade. Parking for 2,207 vehicles would be provided in a shared 4- and 5-level parking garage and 57 spaces are
proposed as on-street parking. In addition, the applicant is proposing to work closely with PSE for the engineering and

capacity needs of the development in order to relocate the powerlines and utility switchgear adjacent to Johns Creek.
Vehicular access to Southport West would be provided by Park Ave N, Lake Washington Blvd N, and the addition of an
internal center road and frontage road.
The site is generally level and consists of gravel yard and asphalt, a Puget Sound Energy switchgear, and an
office/warehouse building. The site contains high seismic hazard areas and the northeast corner of the site contains
Johns Creek and regulated slopes. The soil consists of a loose to medium dense sand, underlain by soft to medium dense
silt, then medium dense to dense sand, very soft silt and clay, and finally dense to very dense silty sand. Groundwater
was observed in the historical exploration at Southport at depths ranging from 3 to 10 feet below existing grade.
Preliminary estimates of cut and fill include approximately 25,000 cubic yards of excavation and 39,200 cubic yards of fill
from an approved source. The depth of excavation is anticipated to not exceed approximately two feet (2’) below ground
level, except for building cores where excavation would be deeper. Stormwater runoff from pollution generating surfaces
would be captured by catch basins and treated in cartridge filter facilities prior to connection into three (3) existing
drainage systems. No significant trees are proposed to be removed. Southport is proposing to plant 115 new trees along
with a variety of shrubs and perennials. The applicant has submitted a Preliminary Geotechnical Report, Technical
Information Report, Traffic Impact Analysis, and Stream Assessment and Final Mitigation Plan with the application.

PROJECT DESCRIPTION: The applicant, Southport West LLC, is requesting Master Plan Review, Hearing Examiner
Site Plan Review and Environmental (SEPA) Review for the construction of Southport West. Southport West is the
completion of the southerly portion of the Southport Development located at the south end of Lake Washington Blvd N.
The proposed expansion of Southport would be located on the 10.09-acre former Puget Sound Energy (PSE) Substation
and PSE utility parcels (APNs 082305-9191 and -9178). The two (2) parcels are located in the Urban Center-2 (UC-2) zone
and the Urban Design District ‘C’. The site is proposed to be developed as five (5) high-rise buildings with approximately
1,200,000 square feet of office and 50,000 of retail development in multiple phases. The proposed first three phases
would be developed as follows: Phase I – Towers 1 and 2 with the garage podium (July 2023 – July 2027), Phase II –
Towers 3 and 4 with garage podium (July 2027 – July 2031), and Phase III – Tower 5 (post July 2031). Phases 1-3 would
start on the south side of the site (closer to Boeing) and would develop to the north side of the lot (closer to Gene Coulon
Memorial Beach Park). A fourth and final phase is being considered for a sixth tower with 130,000 square feet for office
and retail at the south corner of the development near the intersection of Park Ave N and 757th Ave NE. The phased
development could reach as high as 1.6 million gross square feet. The proposed nine-level development would be built
at the same height and scale as the existing Southport offices with an overall height of approximately 154 feet above
average grade. Parking for 2,207 vehicles would be provided in a shared 4- and 5-level parking garage and 57 spaces are
proposed as on-street parking. In addition, the applicant is proposing to work closely with PSE for the engineering and

Vehicular access to Southport West would be provided by Park Ave N, Lake Washington Blvd N, and the addition of an
internal center road and frontage road.
The site is generally level and consists of gravel yard and asphalt, a Puget Sound Energy switchgear, and an
office/warehouse building. The site contains high seismic hazard areas and the northeast corner of the site contains
Johns Creek and regulated slopes. The soil consists of a loose to medium dense sand, underlain by soft to medium dense
silt, then medium dense to dense sand, very soft silt and clay, and finally dense to very dense silty sand. Groundwater
was observed in the historical exploration at Southport at depths ranging from 3 to 10 feet below existing grade.
Preliminary estimates of cut and fill include approximately 25,000 cubic yards of excavation and 39,200 cubic yards of fill
from an approved source. The depth of excavation is anticipated to not exceed approximately two feet (2’) below ground
level, except for building cores where excavation would be deeper. Stormwater runoff from pollution generating surfaces
would be captured by catch basins and treated in cartridge filter facilities prior to connection into three (3) existing

PROJECT DESCRIPTION: The applicant, Southport West LLC, is requesting Master Plan Review, Hearing Examiner
Site Plan Review and Environmental (SEPA) Review for the construction of Southport West. Southport West is the
completion of the southerly portion of the Southport Development located at the south end of Lake Washington Blvd N.
The proposed expansion of Southport would be located on the 10.09-acre former Puget Sound Energy (PSE) Substation
and PSE utility parcels (APNs 082305-9191 and -9178). The two (2) parcels are located in the Urban Center-2 (UC-2) zone
and the Urban Design District ‘C’. The site is proposed to be developed as five (5) high-rise buildings with approximately
1,200,000 square feet of office and 50,000 of retail development in multiple phases. The proposed first three phases
would be developed as follows: Phase I – Towers 1 and 2 with the garage podium (July 2023 – July 2027), Phase II –
Towers 3 and 4 with garage podium (July 2027 – July 2031), and Phase III – Tower 5 (post July 2031). Phases 1-3 would
start on the south side of the site (closer to Boeing) and would develop to the north side of the lot (closer to Gene Coulon
Memorial Beach Park). A fourth and final phase is being considered for a sixth tower with 130,000 square feet for office
and retail at the south corner of the development near the intersection of Park Ave N and 757th Ave NE. The phased
development could reach as high as 1.6 million gross square feet. The proposed nine-level development would be built
at the same height and scale as the existing Southport offices with an overall height of approximately 154 feet above
average grade. Parking for 2,207 vehicles would be provided in a shared 4- and 5-level parking garage and 57 spaces are
proposed as on-street parking. In addition, the applicant is proposing to work closely with PSE for the engineering and

capacity needs of the development in order to relocate the powerlines and utility switchgear adjacent to Johns Creek.
Vehicular access to Southport West would be provided by Park Ave N, Lake Washington Blvd N, and the addition of an
internal center road and frontage road.
The site is generally level and consists of gravel yard and asphalt, a Puget Sound Energy switchgear, and an
office/warehouse building. The site contains high seismic hazard areas and the northeast corner of the site contains
Johns Creek and regulated slopes. The soil consists of a loose to medium dense sand, underlain by soft to medium dense
silt, then medium dense to dense sand, very soft silt and clay, and finally dense to very dense silty sand. Groundwater
was observed in the historical exploration at Southport at depths ranging from 3 to 10 feet below existing grade.
Preliminary estimates of cut and fill include approximately 25,000 cubic yards of excavation and 39,200 cubic yards of fill
from an approved source. The depth of excavation is anticipated to not exceed approximately two feet (2’) below ground
level, except for building cores where excavation would be deeper. Stormwater runoff from pollution generating surfaces
would be captured by catch basins and treated in cartridge filter facilities prior to connection into three (3) existing
drainage systems. No significant trees are proposed to be removed. Southport is proposing to plant 115 new trees along
with a variety of shrubs and perennials. The applicant has submitted a Preliminary Geotechnical Report, Technical
Information Report, Traffic Impact Analysis, and Stream Assessment and Final Mitigation Plan with the application.

capacity needs of the development in order to relocate the powerlines and utility switchgear adjacent to Johns Creek.
Vehicular access to Southport West would be provided by Park Ave N, Lake Washington Blvd N, and the addition of an
internal center road and frontage road.
The site is generally level and consists of gravel yard and asphalt, a Puget Sound Energy switchgear, and an
office/warehouse building. The site contains high seismic hazard areas and the northeast corner of the site contains
Johns Creek and regulated slopes. The soil consists of a loose to medium dense sand, underlain by soft to medium dense
silt, then medium dense to dense sand, very soft silt and clay, and finally dense to very dense silty sand. Groundwater
was observed in the historical exploration at Southport at depths ranging from 3 to 10 feet below existing grade.
Preliminary estimates of cut and fill include approximately 25,000 cubic yards of excavation and 39,200 cubic yards of fill
from an approved source. The depth of excavation is anticipated to not exceed approximately two feet (2’) below ground
level, except for building cores where excavation would be deeper. Stormwater runoff from pollution generating surfaces
would be captured by catch basins and treated in cartridge filter facilities prior to connection into three (3) existing
drainage systems. No significant trees are proposed to be removed. Southport is proposing to plant 115 new trees along
with a variety of shrubs and perennials. The applicant has submitted a Preliminary Geotechnical Report, Technical
Information Report, Traffic Impact Analysis, and Stream Assessment and Final Mitigation Plan with the application.

PROJECT DESCRIPTION: The applicant, Southport West LLC, is requesting Master Plan Review, Hearing Examiner
Site Plan Review and Environmental (SEPA) Review for the construction of Southport West. Southport West is the
completion of the southerly portion of the Southport Development located at the south end of Lake Washington Blvd N.
The proposed expansion of Southport would be located on the 10.09-acre former Puget Sound Energy (PSE) Substation
and PSE utility parcels (APNs 082305-9191 and -9178). The two (2) parcels are located in the Urban Center-2 (UC-2) zone
and the Urban Design District ‘C’. The site is proposed to be developed as five (5) high-rise buildings with approximately
1,200,000 square feet of office and 50,000 of retail development in multiple phases. The proposed first three phases
would be developed as follows: Phase I – Towers 1 and 2 with the garage podium (July 2023 – July 2027), Phase II –
Towers 3 and 4 with garage podium (July 2027 – July 2031), and Phase III – Tower 5 (post July 2031). Phases 1-3 would
start on the south side of the site (closer to Boeing) and would develop to the north side of the lot (closer to Gene Coulon
Memorial Beach Park). A fourth and final phase is being considered for a sixth tower with 130,000 square feet for office
and retail at the south corner of the development near the intersection of Park Ave N and 757th Ave NE. The phased
development could reach as high as 1.6 million gross square feet. The proposed nine-level development would be built
at the same height and scale as the existing Southport offices with an overall height of approximately 154 feet above
average grade. Parking for 2,207 vehicles would be provided in a shared 4- and 5-level parking garage and 57 spaces are
proposed as on-street parking. In addition, the applicant is proposing to work closely with PSE for the engineering and

PROJECT DESCRIPTION: The applicant, Southport West LLC, is requesting Master Plan Review, Hearing Examiner
Site Plan Review and Environmental (SEPA) Review for the construction of Southport West. Southport West is the
completion of the southerly portion of the Southport Development located at the south end of Lake Washington Blvd N.
The proposed expansion of Southport would be located on the 10.09-acre former Puget Sound Energy (PSE) Substation
and PSE utility parcels (APNs 082305-9191 and -9178). The two (2) parcels are located in the Urban Center-2 (UC-2) zone
and the Urban Design District ‘C’. The site is proposed to be developed as five (5) high-rise buildings with approximately
1,200,000 square feet of office and 50,000 of retail development in multiple phases. The proposed first three phases
would be developed as follows: Phase I – Towers 1 and 2 with the garage podium (July 2023 – July 2027), Phase II –
Towers 3 and 4 with garage podium (July 2027 – July 2031), and Phase III – Tower 5 (post July 2031). Phases 1-3 would
start on the south side of the site (closer to Boeing) and would develop to the north side of the lot (closer to Gene Coulon
Memorial Beach Park). A fourth and final phase is being considered for a sixth tower with 130,000 square feet for office
and retail at the south corner of the development near the intersection of Park Ave N and 757th Ave NE. The phased
development could reach as high as 1.6 million gross square feet. The proposed nine-level development would be built
at the same height and scale as the existing Southport offices with an overall height of approximately 154 feet above
average grade. Parking for 2,207 vehicles would be provided in a shared 4- and 5-level parking garage and 57 spaces are
proposed as on-street parking. In addition, the applicant is proposing to work closely with PSE for the engineering and

capacity needs of the development in order to relocate the powerlines and utility switchgear adjacent to Johns Creek.
Vehicular access to Southport West would be provided by Park Ave N, Lake Washington Blvd N, and the addition of an
internal center road and frontage road.
The site is generally level and consists of gravel yard and asphalt, a Puget Sound Energy switchgear, and an
office/warehouse building. The site contains high seismic hazard areas and the northeast corner of the site contains
Johns Creek and regulated slopes. The soil consists of a loose to medium dense sand, underlain by soft to medium dense
silt, then medium dense to dense sand, very soft silt and clay, and finally dense to very dense silty sand. Groundwater
was observed in the historical exploration at Southport at depths ranging from 3 to 10 feet below existing grade.
Preliminary estimates of cut and fill include approximately 25,000 cubic yards of excavation and 39,200 cubic yards of fill
from an approved source. The depth of excavation is anticipated to not exceed approximately two feet (2’) below ground
level, except for building cores where excavation would be deeper. Stormwater runoff from pollution generating surfaces
would be captured by catch basins and treated in cartridge filter facilities prior to connection into three (3) existing
drainage systems. No significant trees are proposed to be removed. Southport is proposing to plant 115 new trees along
with a variety of shrubs and perennials. The applicant has submitted a Preliminary Geotechnical Report, Technical
Information Report, Traffic Impact Analysis, and Stream Assessment and Final Mitigation Plan with the application.

and retail at the south corner of the development near the intersection of Park Ave N and 757th Ave NE. The phased
development could reach as high as 1.6 million gross square feet. The proposed nine-level development would be built
at the same height and scale as the existing Southport offices with an overall height of approximately 154 feet above
average grade. Parking for 2,207 vehicles would be provided in a shared 4- and 5-level parking garage and 57 spaces are
proposed as on-street parking. In addition, the applicant is proposing to work closely with PSE for the engineering and

Vehicular access to Southport West would be provided by Park Ave N, Lake Washington Blvd N, and the addition of an
internal center road and frontage road.
The site is generally level and consists of gravel yard and asphalt, a Puget Sound Energy switchgear, and an
office/warehouse building. The site contains high seismic hazard areas and the northeast corner of the site contains
Johns Creek and regulated slopes. The soil consists of a loose to medium dense sand, underlain by soft to medium dense
silt, then medium dense to dense sand, very soft silt and clay, and finally dense to very dense silty sand. Groundwater
was observed in the historical exploration at Southport at depths ranging from 3 to 10 feet below existing grade.
Preliminary estimates of cut and fill include approximately 25,000 cubic yards of excavation and 39,200 cubic yards of fill
from an approved source. The depth of excavation is anticipated to not exceed approximately two feet (2’) below ground
level, except for building cores where excavation would be deeper. Stormwater runoff from pollution generating surfaces
would be captured by catch basins and treated in cartridge filter facilities prior to connection into three (3) existing
drainage systems. No significant trees are proposed to be removed. Southport is proposing to plant 115 new trees along
with a variety of shrubs and perennials. The applicant has submitted a Preliminary Geotechnical Report, Technical
Information Report, Traffic Impact Analysis, and Stream Assessment and Final Mitigation Plan with the application.

PROJECT DESCRIPTION: The applicant, Southport West LLC, is requesting Master Plan Review, Hearing Examiner
Site Plan Review and Environmental (SEPA) Review for the construction of Southport West. Southport West is the
completion of the southerly portion of the Southport Development located at the south end of Lake Washington Blvd N.
The proposed expansion of Southport would be located on the 10.09-acre former Puget Sound Energy (PSE) Substation
and PSE utility parcels (APNs 082305-9191 and -9178). The two (2) parcels are located in the Urban Center-2 (UC-2) zone
and the Urban Design District ‘C’. The site is proposed to be developed as five (5) high-rise buildings with approximately
1,200,000 square feet of office and 50,000 of retail development in multiple phases. The proposed first three phases
would be developed as follows: Phase I – Towers 1 and 2 with the garage podium (July 2023 – July 2027), Phase II –
Towers 3 and 4 with garage podium (July 2027 – July 2031), and Phase III – Tower 5 (post July 2031). Phases 1-3 would
start on the south side of the site (closer to Boeing) and would develop to the north side of the lot (closer to Gene Coulon
Memorial Beach Park). A fourth and final phase is being considered for a sixth tower with 130,000 square feet for office
and retail at the south corner of the development near the intersection of Park Ave N and 757th Ave NE. The phased
development could reach as high as 1.6 million gross square feet. The proposed nine-level development would be built
at the same height and scale as the existing Southport offices with an overall height of approximately 154 feet above
average grade. Parking for 2,207 vehicles would be provided in a shared 4- and 5-level parking garage and 57 spaces are
proposed as on-street parking. In addition, the applicant is proposing to work closely with PSE for the engineering and

capacity needs of the development in order to relocate the powerlines and utility switchgear adjacent to Johns Creek.
Vehicular access to Southport West would be provided by Park Ave N, Lake Washington Blvd N, and the addition of an
internal center road and frontage road.
The site is generally level and consists of gravel yard and asphalt, a Puget Sound Energy switchgear, and an
office/warehouse building. The site contains high seismic hazard areas and the northeast corner of the site contains
Johns Creek and regulated slopes. The soil consists of a loose to medium dense sand, underlain by soft to medium dense
silt, then medium dense to dense sand, very soft silt and clay, and finally dense to very dense silty sand. Groundwater
was observed in the historical exploration at Southport at depths ranging from 3 to 10 feet below existing grade.
Preliminary estimates of cut and fill include approximately 25,000 cubic yards of excavation and 39,200 cubic yards of fill
from an approved source. The depth of excavation is anticipated to not exceed approximately two feet (2’) below ground
level, except for building cores where excavation would be deeper. Stormwater runoff from pollution generating surfaces
would be captured by catch basins and treated in cartridge filter facilities prior to connection into three (3) existing
drainage systems. No significant trees are proposed to be removed. Southport is proposing to plant 115 new trees along
with a variety of shrubs and perennials. The applicant has submitted a Preliminary Geotechnical Report, Technical
Information Report, Traffic Impact Analysis, and Stream Assessment and Final Mitigation Plan with the application.

PROJECT DESCRIPTION: The applicant, Southport West LLC, is requesting Master Plan Review, Hearing Examiner
Site Plan Review and Environmental (SEPA) Review for the construction of Southport West. Southport West is the
completion of the southerly portion of the Southport Development located at the south end of Lake Washington Blvd N.
The proposed expansion of Southport would be located on the 10.09-acre former Puget Sound Energy (PSE) Substation
and PSE utility parcels (APNs 082305-9191 and -9178). The two (2) parcels are located in the Urban Center-2 (UC-2) zone
and the Urban Design District ‘C’. The site is proposed to be developed as five (5) high-rise buildings with approximately
1,200,000 square feet of office and 50,000 of retail development in multiple phases. The proposed first three phases
would be developed as follows: Phase I – Towers 1 and 2 with the garage podium (July 2023 – July 2027), Phase II –
Towers 3 and 4 with garage podium (July 2027 – July 2031), and Phase III – Tower 5 (post July 2031). Phases 1-3 would
start on the south side of the site (closer to Boeing) and would develop to the north side of the lot (closer to Gene Coulon
Memorial Beach Park). A fourth and final phase is being considered for a sixth tower with 130,000 square feet for office
and retail at the south corner of the development near the intersection of Park Ave N and 757th Ave NE. The phased
development could reach as high as 1.6 million gross square feet. The proposed nine-level development would be built
at the same height and scale as the existing Southport offices with an overall height of approximately 154 feet above
average grade. Parking for 2,207 vehicles would be provided in a shared 4- and 5-level parking garage and 57 spaces are
proposed as on-street parking. In addition, the applicant is proposing to work closely with PSE for the engineering and

capacity needs of the development in order to relocate the powerlines and utility switchgear adjacent to Johns Creek.
Vehicular access to Southport West would be provided by Park Ave N, Lake Washington Blvd N, and the addition of an
internal center road and frontage road.
The site is generally level and consists of gravel yard and asphalt, a Puget Sound Energy switchgear, and an
office/warehouse building. The site contains high seismic hazard areas and the northeast corner of the site contains
Johns Creek and regulated slopes. The soil consists of a loose to medium dense sand, underlain by soft to medium dense
silt, then medium dense to dense sand, very soft silt and clay, and finally dense to very dense silty sand. Groundwater
was observed in the historical exploration at Southport at depths ranging from 3 to 10 feet below existing grade.
Preliminary estimates of cut and fill include approximately 25,000 cubic yards of excavation and 39,200 cubic yards of fill
from an approved source. The depth of excavation is anticipated to not exceed approximately two feet (2’) below ground
level, except for building cores where excavation would be deeper. Stormwater runoff from pollution generating surfaces
would be captured by catch basins and treated in cartridge filter facilities prior to connection into three (3) existing
drainage systems. No significant trees are proposed to be removed. Southport is proposing to plant 115 new trees along
with a variety of shrubs and perennials. The applicant has submitted a Preliminary Geotechnical Report, Technical
Information Report, Traffic Impact Analysis, and Stream Assessment and Final Mitigation Plan with the application.

office/warehouse building. The site contains high seismic hazard areas and the northeast corner of the site contains
Johns Creek and regulated slopes. The soil consists of a loose to medium dense sand, underlain by soft to medium dense
silt, then medium dense to dense sand, very soft silt and clay, and finally dense to very dense silty sand. Groundwater
was observed in the historical exploration at Southport at depths ranging from 3 to 10 feet below existing grade.
Preliminary estimates of cut and fill include approximately 25,000 cubic yards of excavation and 39,200 cubic yards of fill
from an approved source. The depth of excavation is anticipated to not exceed approximately two feet (2’) below ground
level, except for building cores where excavation would be deeper. Stormwater runoff from pollution generating surfaces
would be captured by catch basins and treated in cartridge filter facilities prior to connection into three (3) existing
drainage systems. No significant trees are proposed to be removed. Southport is proposing to plant 115 new trees along
with a variety of shrubs and perennials. The applicant has submitted a Preliminary Geotechnical Report, Technical
Information Report, Traffic Impact Analysis, and Stream Assessment and Final Mitigation Plan with the application.

Site Plan Review and Environmental (SEPA) Review for the construction of Southport West. Southport West is the
completion of the southerly portion of the Southport Development located at the south end of Lake Washington Blvd N.
The proposed expansion of Southport would be located on the 10.09-acre former Puget Sound Energy (PSE) Substation
and PSE utility parcels (APNs 082305-9191 and -9178). The two (2) parcels are located in the Urban Center-2 (UC-2) zone
and the Urban Design District ‘C’. The site is proposed to be developed as five (5) high-rise buildings with approximately
1,200,000 square feet of office and 50,000 of retail development in multiple phases. The proposed first three phases
would be developed as follows: Phase I – Towers 1 and 2 with the garage podium (July 2023 – July 2027), Phase II –
Towers 3 and 4 with garage podium (July 2027 – July 2031), and Phase III – Tower 5 (post July 2031). Phases 1-3 would
start on the south side of the site (closer to Boeing) and would develop to the north side of the lot (closer to Gene Coulon
Memorial Beach Park). A fourth and final phase is being considered for a sixth tower with 130,000 square feet for office
and retail at the south corner of the development near the intersection of Park Ave N and 757th Ave NE. The phased
development could reach as high as 1.6 million gross square feet. The proposed nine-level development would be built
at the same height and scale as the existing Southport offices with an overall height of approximately 154 feet above
average grade. Parking for 2,207 vehicles would be provided in a shared 4- and 5-level parking garage and 57 spaces are
proposed as on-street parking. In addition, the applicant is proposing to work closely with PSE for the engineering and

PROJECT DESCRIPTION: The applicant, Southport West LLC, is requesting Master Plan Review, Hearing Examiner
Site Plan Review and Environmental (SEPA) Review for the construction of Southport West. Southport West is the
completion of the southerly portion of the Southport Development located at the south end of Lake Washington Blvd N.
The proposed expansion of Southport would be located on the 10.09-acre former Puget Sound Energy (PSE) Substation
and PSE utility parcels (APNs 082305-9191 and -9178). The two (2) parcels are located in the Urban Center-2 (UC-2) zone
and the Urban Design District ‘C’. The site is proposed to be developed as five (5) high-rise buildings with approximately
1,200,000 square feet of office and 50,000 of retail development in multiple phases. The proposed first three phases
would be developed as follows: Phase I – Towers 1 and 2 with the garage podium (July 2023 – July 2027), Phase II –
Towers 3 and 4 with garage podium (July 2027 – July 2031), and Phase III – Tower 5 (post July 2031). Phases 1-3 would
start on the south side of the site (closer to Boeing) and would develop to the north side of the lot (closer to Gene Coulon
Memorial Beach Park). A fourth and final phase is being considered for a sixth tower with 130,000 square feet for office
and retail at the south corner of the development near the intersection of Park Ave N and 757th Ave NE. The phased
development could reach as high as 1.6 million gross square feet. The proposed nine-level development would be built
at the same height and scale as the existing Southport offices with an overall height of approximately 154 feet above
average grade. Parking for 2,207 vehicles would be provided in a shared 4- and 5-level parking garage and 57 spaces are
proposed as on-street parking. In addition, the applicant is proposing to work closely with PSE for the engineering and

capacity needs of the development in order to relocate the powerlines and utility switchgear adjacent to Johns Creek.
Vehicular access to Southport West would be provided by Park Ave N, Lake Washington Blvd N, and the addition of an
internal center road and frontage road.
The site is generally level and consists of gravel yard and asphalt, a Puget Sound Energy switchgear, and an
office/warehouse building. The site contains high seismic hazard areas and the northeast corner of the site contains
Johns Creek and regulated slopes. The soil consists of a loose to medium dense sand, underlain by soft to medium dense
silt, then medium dense to dense sand, very soft silt and clay, and finally dense to very dense silty sand. Groundwater
was observed in the historical exploration at Southport at depths ranging from 3 to 10 feet below existing grade.
Preliminary estimates of cut and fill include approximately 25,000 cubic yards of excavation and 39,200 cubic yards of fill
from an approved source. The depth of excavation is anticipated to not exceed approximately two feet (2’) below ground
level, except for building cores where excavation would be deeper. Stormwater runoff from pollution generating surfaces
would be captured by catch basins and treated in cartridge filter facilities prior to connection into three (3) existing
drainage systems. No significant trees are proposed to be removed. Southport is proposing to plant 115 new trees along
with a variety of shrubs and perennials. The applicant has submitted a Preliminary Geotechnical Report, Technical
Information Report, Traffic Impact Analysis, and Stream Assessment and Final Mitigation Plan with the application.

capacity needs of the development in order to relocate the powerlines and utility switchgear adjacent to Johns Creek.
Vehicular access to Southport West would be provided by Park Ave N, Lake Washington Blvd N, and the addition of an
internal center road and frontage road.
The site is generally level and consists of gravel yard and asphalt, a Puget Sound Energy switchgear, and an
office/warehouse building. The site contains high seismic hazard areas and the northeast corner of the site contains
Johns Creek and regulated slopes. The soil consists of a loose to medium dense sand, underlain by soft to medium dense
silt, then medium dense to dense sand, very soft silt and clay, and finally dense to very dense silty sand. Groundwater
was observed in the historical exploration at Southport at depths ranging from 3 to 10 feet below existing grade.
Preliminary estimates of cut and fill include approximately 25,000 cubic yards of excavation and 39,200 cubic yards of fill
from an approved source. The depth of excavation is anticipated to not exceed approximately two feet (2’) below ground
level, except for building cores where excavation would be deeper. Stormwater runoff from pollution generating surfaces
would be captured by catch basins and treated in cartridge filter facilities prior to connection into three (3) existing
drainage systems. No significant trees are proposed to be removed. Southport is proposing to plant 115 new trees along
with a variety of shrubs and perennials. The applicant has submitted a Preliminary Geotechnical Report, Technical
Information Report, Traffic Impact Analysis, and Stream Assessment and Final Mitigation Plan with the application.

The proposed expansion of Southport would be located on the 10.09-acre former Puget Sound Energy (PSE) Substation
and PSE utility parcels (APNs 082305-9191 and -9178). The two (2) parcels are located in the Urban Center-2 (UC-2) zone
and the Urban Design District ‘C’. The site is proposed to be developed as five (5) high-rise buildings with approximately
1,200,000 square feet of office and 50,000 of retail development in multiple phases. The proposed first three phases
would be developed as follows: Phase I – Towers 1 and 2 with the garage podium (July 2023 – July 2027), Phase II –
Towers 3 and 4 with garage podium (July 2027 – July 2031), and Phase III – Tower 5 (post July 2031). Phases 1-3 would
start on the south side of the site (closer to Boeing) and would develop to the north side of the lot (closer to Gene Coulon
Memorial Beach Park). A fourth and final phase is being considered for a sixth tower with 130,000 square feet for office
and retail at the south corner of the development near the intersection of Park Ave N and 757th Ave NE. The phased
development could reach as high as 1.6 million gross square feet. The proposed nine-level development would be built
at the same height and scale as the existing Southport offices with an overall height of approximately 154 feet above
average grade. Parking for 2,207 vehicles would be provided in a shared 4- and 5-level parking garage and 57 spaces are

PROJECT DESCRIPTION: The applicant, Southport West LLC, is requesting Master Plan Review, Hearing Examiner
Site Plan Review and Environmental (SEPA) Review for the construction of Southport West. Southport West is the
completion of the southerly portion of the Southport Development located at the south end of Lake Washington Blvd N.
The proposed expansion of Southport would be located on the 10.09-acre former Puget Sound Energy (PSE) Substation
and PSE utility parcels (APNs 082305-9191 and -9178). The two (2) parcels are located in the Urban Center-2 (UC-2) zone
and the Urban Design District ‘C’. The site is proposed to be developed as five (5) high-rise buildings with approximately
1,200,000 square feet of office and 50,000 of retail development in multiple phases. The proposed first three phases
would be developed as follows: Phase I – Towers 1 and 2 with the garage podium (July 2023 – July 2027), Phase II –
Towers 3 and 4 with garage podium (July 2027 – July 2031), and Phase III – Tower 5 (post July 2031). Phases 1-3 would
start on the south side of the site (closer to Boeing) and would develop to the north side of the lot (closer to Gene Coulon
Memorial Beach Park). A fourth and final phase is being considered for a sixth tower with 130,000 square feet for office
and retail at the south corner of the development near the intersection of Park Ave N and 757th Ave NE. The phased
development could reach as high as 1.6 million gross square feet. The proposed nine-level development would be built
at the same height and scale as the existing Southport offices with an overall height of approximately 154 feet above
average grade. Parking for 2,207 vehicles would be provided in a shared 4- and 5-level parking garage and 57 spaces are
proposed as on-street parking. In addition, the applicant is proposing to work closely with PSE for the engineering and

capacity needs of the development in order to relocate the powerlines and utility switchgear adjacent to Johns Creek.
Vehicular access to Southport West would be provided by Park Ave N, Lake Washington Blvd N, and the addition of an
internal center road and frontage road.
The site is generally level and consists of gravel yard and asphalt, a Puget Sound Energy switchgear, and an
office/warehouse building. The site contains high seismic hazard areas and the northeast corner of the site contains
Johns Creek and regulated slopes. The soil consists of a loose to medium dense sand, underlain by soft to medium dense
silt, then medium dense to dense sand, very soft silt and clay, and finally dense to very dense silty sand. Groundwater
was observed in the historical exploration at Southport at depths ranging from 3 to 10 feet below existing grade.
Preliminary estimates of cut and fill include approximately 25,000 cubic yards of excavation and 39,200 cubic yards of fill
from an approved source. The depth of excavation is anticipated to not exceed approximately two feet (2’) below ground
level, except for building cores where excavation would be deeper. Stormwater runoff from pollution generating surfaces
would be captured by catch basins and treated in cartridge filter facilities prior to connection into three (3) existing
drainage systems. No significant trees are proposed to be removed. Southport is proposing to plant 115 new trees along
with a variety of shrubs and perennials. The applicant has submitted a Preliminary Geotechnical Report, Technical
Information Report, Traffic Impact Analysis, and Stream Assessment and Final Mitigation Plan with the application.

and PSE utility parcels (APNs 082305-9191 and -9178). The two (2) parcels are located in the Urban Center-2 (UC-2) zone
and the Urban Design District ‘C’. The site is proposed to be developed as five (5) high-rise buildings with approximately
1,200,000 square feet of office and 50,000 of retail development in multiple phases. The proposed first three phases
would be developed as follows: Phase I – Towers 1 and 2 with the garage podium (July 2023 – July 2027), Phase II –
Towers 3 and 4 with garage podium (July 2027 – July 2031), and Phase III – Tower 5 (post July 2031). Phases 1-3 would
start on the south side of the site (closer to Boeing) and would develop to the north side of the lot (closer to Gene Coulon
Memorial Beach Park). A fourth and final phase is being considered for a sixth tower with 130,000 square feet for office
and retail at the south corner of the development near the intersection of Park Ave N and 757th Ave NE. The phased
development could reach as high as 1.6 million gross square feet. The proposed nine-level development would be built
at the same height and scale as the existing Southport offices with an overall height of approximately 154 feet above
average grade. Parking for 2,207 vehicles would be provided in a shared 4- and 5-level parking garage and 57 spaces are
proposed as on-street parking. In addition, the applicant is proposing to work closely with PSE for the engineering and

capacity needs of the development in order to relocate the powerlines and utility switchgear adjacent to Johns Creek.
Vehicular access to Southport West would be provided by Park Ave N, Lake Washington Blvd N, and the addition of an
internal center road and frontage road.
The site is generally level and consists of gravel yard and asphalt, a Puget Sound Energy switchgear, and an
office/warehouse building. The site contains high seismic hazard areas and the northeast corner of the site contains
Johns Creek and regulated slopes. The soil consists of a loose to medium dense sand, underlain by soft to medium dense
silt, then medium dense to dense sand, very soft silt and clay, and finally dense to very dense silty sand. Groundwater
was observed in the historical exploration at Southport at depths ranging from 3 to 10 feet below existing grade.
Preliminary estimates of cut and fill include approximately 25,000 cubic yards of excavation and 39,200 cubic yards of fill
from an approved source. The depth of excavation is anticipated to not exceed approximately two feet (2’) below ground
level, except for building cores where excavation would be deeper. Stormwater runoff from pollution generating surfaces
would be captured by catch basins and treated in cartridge filter facilities prior to connection into three (3) existing
drainage systems. No significant trees are proposed to be removed. Southport is proposing to plant 115 new trees along
with a variety of shrubs and perennials. The applicant has submitted a Preliminary Geotechnical Report, Technical
Information Report, Traffic Impact Analysis, and Stream Assessment and Final Mitigation Plan with the application.

PROJECT DESCRIPTION: The applicant, Southport West LLC, is requesting Master Plan Review, Hearing Examiner
Site Plan Review and Environmental (SEPA) Review for the construction of Southport West. Southport West is the
completion of the southerly portion of the Southport Development located at the south end of Lake Washington Blvd N.
The proposed expansion of Southport would be located on the 10.09-acre former Puget Sound Energy (PSE) Substation
and PSE utility parcels (APNs 082305-9191 and -9178). The two (2) parcels are located in the Urban Center-2 (UC-2) zone
and the Urban Design District ‘C’. The site is proposed to be developed as five (5) high-rise buildings with approximately
1,200,000 square feet of office and 50,000 of retail development in multiple phases. The proposed first three phases
would be developed as follows: Phase I – Towers 1 and 2 with the garage podium (July 2023 – July 2027), Phase II –
Towers 3 and 4 with garage podium (July 2027 – July 2031), and Phase III – Tower 5 (post July 2031). Phases 1-3 would
start on the south side of the site (closer to Boeing) and would develop to the north side of the lot (closer to Gene Coulon
Memorial Beach Park). A fourth and final phase is being considered for a sixth tower with 130,000 square feet for office
and retail at the south corner of the development near the intersection of Park Ave N and 757th Ave NE. The phased
development could reach as high as 1.6 million gross square feet. The proposed nine-level development would be built
at the same height and scale as the existing Southport offices with an overall height of approximately 154 feet above
average grade. Parking for 2,207 vehicles would be provided in a shared 4- and 5-level parking garage and 57 spaces are
proposed as on-street parking. In addition, the applicant is proposing to work closely with PSE for the engineering and

Vehicular access to Southport West would be provided by Park Ave N, Lake Washington Blvd N, and the addition of an
internal center road and frontage road.
The site is generally level and consists of gravel yard and asphalt, a Puget Sound Energy switchgear, and an
office/warehouse building. The site contains high seismic hazard areas and the northeast corner of the site contains
Johns Creek and regulated slopes. The soil consists of a loose to medium dense sand, underlain by soft to medium dense
silt, then medium dense to dense sand, very soft silt and clay, and finally dense to very dense silty sand. Groundwater
was observed in the historical exploration at Southport at depths ranging from 3 to 10 feet below existing grade.
Preliminary estimates of cut and fill include approximately 25,000 cubic yards of excavation and 39,200 cubic yards of fill
from an approved source. The depth of excavation is anticipated to not exceed approximately two feet (2’) below ground
level, except for building cores where excavation would be deeper. Stormwater runoff from pollution generating surfaces
would be captured by catch basins and treated in cartridge filter facilities prior to connection into three (3) existing
drainage systems. No significant trees are proposed to be removed. Southport is proposing to plant 115 new trees along
with a variety of shrubs and perennials. The applicant has submitted a Preliminary Geotechnical Report, Technical
Information Report, Traffic Impact Analysis, and Stream Assessment and Final Mitigation Plan with the application.

PROJECT DESCRIPTION: The applicant, Southport West LLC, is requesting Master Plan Review, Hearing Examiner
Site Plan Review and Environmental (SEPA) Review for the construction of Southport West. Southport West is the
completion of the southerly portion of the Southport Development located at the south end of Lake Washington Blvd N.
The proposed expansion of Southport would be located on the 10.09-acre former Puget Sound Energy (PSE) Substation
and PSE utility parcels (APNs 082305-9191 and -9178). The two (2) parcels are located in the Urban Center-2 (UC-2) zone
and the Urban Design District ‘C’. The site is proposed to be developed as five (5) high-rise buildings with approximately
1,200,000 square feet of office and 50,000 of retail development in multiple phases. The proposed first three phases
would be developed as follows: Phase I – Towers 1 and 2 with the garage podium (July 2023 – July 2027), Phase II –
Towers 3 and 4 with garage podium (July 2027 – July 2031), and Phase III – Tower 5 (post July 2031). Phases 1-3 would
start on the south side of the site (closer to Boeing) and would develop to the north side of the lot (closer to Gene Coulon
Memorial Beach Park). A fourth and final phase is being considered for a sixth tower with 130,000 square feet for office
and retail at the south corner of the development near the intersection of Park Ave N and 757th Ave NE. The phased
development could reach as high as 1.6 million gross square feet. The proposed nine-level development would be built
at the same height and scale as the existing Southport offices with an overall height of approximately 154 feet above
average grade. Parking for 2,207 vehicles would be provided in a shared 4- and 5-level parking garage and 57 spaces are
proposed as on-street parking. In addition, the applicant is proposing to work closely with PSE for the engineering and

capacity needs of the development in order to relocate the powerlines and utility switchgear adjacent to Johns Creek.
Vehicular access to Southport West would be provided by Park Ave N, Lake Washington Blvd N, and the addition of an
internal center road and frontage road.
The site is generally level and consists of gravel yard and asphalt, a Puget Sound Energy switchgear, and an
office/warehouse building. The site contains high seismic hazard areas and the northeast corner of the site contains
Johns Creek and regulated slopes. The soil consists of a loose to medium dense sand, underlain by soft to medium dense
silt, then medium dense to dense sand, very soft silt and clay, and finally dense to very dense silty sand. Groundwater
was observed in the historical exploration at Southport at depths ranging from 3 to 10 feet below existing grade.
Preliminary estimates of cut and fill include approximately 25,000 cubic yards of excavation and 39,200 cubic yards of fill
from an approved source. The depth of excavation is anticipated to not exceed approximately two feet (2’) below ground
level, except for building cores where excavation would be deeper. Stormwater runoff from pollution generating surfaces
would be captured by catch basins and treated in cartridge filter facilities prior to connection into three (3) existing
drainage systems. No significant trees are proposed to be removed. Southport is proposing to plant 115 new trees along
with a variety of shrubs and perennials. The applicant has submitted a Preliminary Geotechnical Report, Technical
Information Report, Traffic Impact Analysis, and Stream Assessment and Final Mitigation Plan with the application.

capacity needs of the development in order to relocate the powerlines and utility switchgear adjacent to Johns Creek.
Vehicular access to Southport West would be provided by Park Ave N, Lake Washington Blvd N, and the addition of an
internal center road and frontage road.
The site is generally level and consists of gravel yard and asphalt, a Puget Sound Energy switchgear, and an
office/warehouse building. The site contains high seismic hazard areas and the northeast corner of the site contains
Johns Creek and regulated slopes. The soil consists of a loose to medium dense sand, underlain by soft to medium dense
silt, then medium dense to dense sand, very soft silt and clay, and finally dense to very dense silty sand. Groundwater
was observed in the historical exploration at Southport at depths ranging from 3 to 10 feet below existing grade.
Preliminary estimates of cut and fill include approximately 25,000 cubic yards of excavation and 39,200 cubic yards of fill
from an approved source. The depth of excavation is anticipated to not exceed approximately two feet (2’) below ground
level, except for building cores where excavation would be deeper. Stormwater runoff from pollution generating surfaces
would be captured by catch basins and treated in cartridge filter facilities prior to connection into three (3) existing
drainage systems. No significant trees are proposed to be removed. Southport is proposing to plant 115 new trees along
with a variety of shrubs and perennials. The applicant has submitted a Preliminary Geotechnical Report, Technical
Information Report, Traffic Impact Analysis, and Stream Assessment and Final Mitigation Plan with the application.

Site Plan Review and Environmental (SEPA) Review for the construction of Southport West. Southport West is the
completion of the southerly portion of the Southport Development located at the south end of Lake Washington Blvd N.
The proposed expansion of Southport would be located on the 10.09-acre former Puget Sound Energy (PSE) Substation
and PSE utility parcels (APNs 082305-9191 and -9178). The two (2) parcels are located in the Urban Center-2 (UC-2) zone
and the Urban Design District ‘C’. The site is proposed to be developed as five (5) high-rise buildings with approximately
1,200,000 square feet of office and 50,000 of retail development in multiple phases. The proposed first three phases
would be developed as follows: Phase I – Towers 1 and 2 with the garage podium (July 2023 – July 2027), Phase II –
Towers 3 and 4 with garage podium (July 2027 – July 2031), and Phase III – Tower 5 (post July 2031). Phases 1-3 would
start on the south side of the site (closer to Boeing) and would develop to the north side of the lot (closer to Gene Coulon
Memorial Beach Park). A fourth and final phase is being considered for a sixth tower with 130,000 square feet for office
and retail at the south corner of the development near the intersection of Park Ave N and 757th Ave NE. The phased
development could reach as high as 1.6 million gross square feet. The proposed nine-level development would be built
at the same height and scale as the existing Southport offices with an overall height of approximately 154 feet above
average grade. Parking for 2,207 vehicles would be provided in a shared 4- and 5-level parking garage and 57 spaces are
proposed as on-street parking. In addition, the applicant is proposing to work closely with PSE for the engineering and

PROJECT DESCRIPTION: The applicant, Southport West LLC, is requesting Master Plan Review, Hearing Examiner
Site Plan Review and Environmental (SEPA) Review for the construction of Southport West. Southport West is the
completion of the southerly portion of the Southport Development located at the south end of Lake Washington Blvd N.
The proposed expansion of Southport would be located on the 10.09-acre former Puget Sound Energy (PSE) Substation
and PSE utility parcels (APNs 082305-9191 and -9178). The two (2) parcels are located in the Urban Center-2 (UC-2) zone
and the Urban Design District ‘C’. The site is proposed to be developed as five (5) high-rise buildings with approximately
1,200,000 square feet of office and 50,000 of retail development in multiple phases. The proposed first three phases
would be developed as follows: Phase I – Towers 1 and 2 with the garage podium (July 2023 – July 2027), Phase II –
Towers 3 and 4 with garage podium (July 2027 – July 2031), and Phase III – Tower 5 (post July 2031). Phases 1-3 would
start on the south side of the site (closer to Boeing) and would develop to the north side of the lot (closer to Gene Coulon
Memorial Beach Park). A fourth and final phase is being considered for a sixth tower with 130,000 square feet for office
and retail at the south corner of the development near the intersection of Park Ave N and 757th Ave NE. The phased
development could reach as high as 1.6 million gross square feet. The proposed nine-level development would be built
at the same height and scale as the existing Southport offices with an overall height of approximately 154 feet above
average grade. Parking for 2,207 vehicles would be provided in a shared 4- and 5-level parking garage and 57 spaces are
proposed as on-street parking. In addition, the applicant is proposing to work closely with PSE for the engineering and

capacity needs of the development in order to relocate the powerlines and utility switchgear adjacent to Johns Creek.
Vehicular access to Southport West would be provided by Park Ave N, Lake Washington Blvd N, and the addition of an
internal center road and frontage road.
The site is generally level and consists of gravel yard and asphalt, a Puget Sound Energy switchgear, and an
office/warehouse building. The site contains high seismic hazard areas and the northeast corner of the site contains
Johns Creek and regulated slopes. The soil consists of a loose to medium dense sand, underlain by soft to medium dense
silt, then medium dense to dense sand, very soft silt and clay, and finally dense to very dense silty sand. Groundwater
was observed in the historical exploration at Southport at depths ranging from 3 to 10 feet below existing grade.
Preliminary estimates of cut and fill include approximately 25,000 cubic yards of excavation and 39,200 cubic yards of fill
from an approved source. The depth of excavation is anticipated to not exceed approximately two feet (2’) below ground
level, except for building cores where excavation would be deeper. Stormwater runoff from pollution generating surfaces
would be captured by catch basins and treated in cartridge filter facilities prior to connection into three (3) existing
drainage systems. No significant trees are proposed to be removed. Southport is proposing to plant 115 new trees along
with a variety of shrubs and perennials. The applicant has submitted a Preliminary Geotechnical Report, Technical
Information Report, Traffic Impact Analysis, and Stream Assessment and Final Mitigation Plan with the application.

Vehicular access to Southport West would be provided by Park Ave N, Lake Washington Blvd N, and the addition of an
internal center road and frontage road.
The site is generally level and consists of gravel yard and asphalt, a Puget Sound Energy switchgear, and an
office/warehouse building. The site contains high seismic hazard areas and the northeast corner of the site contains
Johns Creek and regulated slopes. The soil consists of a loose to medium dense sand, underlain by soft to medium dense
silt, then medium dense to dense sand, very soft silt and clay, and finally dense to very dense silty sand. Groundwater
was observed in the historical exploration at Southport at depths ranging from 3 to 10 feet below existing grade.
Preliminary estimates of cut and fill include approximately 25,000 cubic yards of excavation and 39,200 cubic yards of fill
from an approved source. The depth of excavation is anticipated to not exceed approximately two feet (2’) below ground
level, except for building cores where excavation would be deeper. Stormwater runoff from pollution generating surfaces
would be captured by catch basins and treated in cartridge filter facilities prior to connection into three (3) existing
drainage systems. No significant trees are proposed to be removed. Southport is proposing to plant 115 new trees along
with a variety of shrubs and perennials. The applicant has submitted a Preliminary Geotechnical Report, Technical
Information Report, Traffic Impact Analysis, and Stream Assessment and Final Mitigation Plan with the application.

PROJECT DESCRIPTION: The applicant, Southport West LLC, is requesting Master Plan Review, Hearing Examiner
Site Plan Review and Environmental (SEPA) Review for the construction of Southport West. Southport West is the
completion of the southerly portion of the Southport Development located at the south end of Lake Washington Blvd N.
The proposed expansion of Southport would be located on the 10.09-acre former Puget Sound Energy (PSE) Substation
and PSE utility parcels (APNs 082305-9191 and -9178). The two (2) parcels are located in the Urban Center-2 (UC-2) zone
and the Urban Design District ‘C’. The site is proposed to be developed as five (5) high-rise buildings with approximately
1,200,000 square feet of office and 50,000 of retail development in multiple phases. The proposed first three phases
would be developed as follows: Phase I – Towers 1 and 2 with the garage podium (July 2023 – July 2027), Phase II –
Towers 3 and 4 with garage podium (July 2027 – July 2031), and Phase III – Tower 5 (post July 2031). Phases 1-3 would
start on the south side of the site (closer to Boeing) and would develop to the north side of the lot (closer to Gene Coulon
Memorial Beach Park). A fourth and final phase is being considered for a sixth tower with 130,000 square feet for office
and retail at the south corner of the development near the intersection of Park Ave N and 757th Ave NE. The phased
development could reach as high as 1.6 million gross square feet. The proposed nine-level development would be built
at the same height and scale as the existing Southport offices with an overall height of approximately 154 feet above
average grade. Parking for 2,207 vehicles would be provided in a shared 4- and 5-level parking garage and 57 spaces are
proposed as on-street parking. In addition, the applicant is proposing to work closely with PSE for the engineering and

capacity needs of the development in order to relocate the powerlines and utility switchgear adjacent to Johns Creek.
Vehicular access to Southport West would be provided by Park Ave N, Lake Washington Blvd N, and the addition of an
internal center road and frontage road.
The site is generally level and consists of gravel yard and asphalt, a Puget Sound Energy switchgear, and an
office/warehouse building. The site contains high seismic hazard areas and the northeast corner of the site contains
Johns Creek and regulated slopes. The soil consists of a loose to medium dense sand, underlain by soft to medium dense
silt, then medium dense to dense sand, very soft silt and clay, and finally dense to very dense silty sand. Groundwater
was observed in the historical exploration at Southport at depths ranging from 3 to 10 feet below existing grade.
Preliminary estimates of cut and fill include approximately 25,000 cubic yards of excavation and 39,200 cubic yards of fill
from an approved source. The depth of excavation is anticipated to not exceed approximately two feet (2’) below ground
level, except for building cores where excavation would be deeper. Stormwater runoff from pollution generating surfaces
would be captured by catch basins and treated in cartridge filter facilities prior to connection into three (3) existing
drainage systems. No significant trees are proposed to be removed. Southport is proposing to plant 115 new trees along
with a variety of shrubs and perennials. The applicant has submitted a Preliminary Geotechnical Report, Technical
Information Report, Traffic Impact Analysis, and Stream Assessment and Final Mitigation Plan with the application.

PROJECT DESCRIPTION: The applicant, Southport West LLC, is requesting Master Plan Review, Hearing Examiner
Site Plan Review and Environmental (SEPA) Review for the construction of Southport West. Southport West is the
completion of the southerly portion of the Southport Development located at the south end of Lake Washington Blvd N.
The proposed expansion of Southport would be located on the 10.09-acre former Puget Sound Energy (PSE) Substation
and PSE utility parcels (APNs 082305-9191 and -9178). The two (2) parcels are located in the Urban Center-2 (UC-2) zone
and the Urban Design District ‘C’. The site is proposed to be developed as five (5) high-rise buildings with approximately
1,200,000 square feet of office and 50,000 of retail development in multiple phases. The proposed first three phases
would be developed as follows: Phase I – Towers 1 and 2 with the garage podium (July 2023 – July 2027), Phase II –
Towers 3 and 4 with garage podium (July 2027 – July 2031), and Phase III – Tower 5 (post July 2031). Phases 1-3 would
start on the south side of the site (closer to Boeing) and would develop to the north side of the lot (closer to Gene Coulon
Memorial Beach Park). A fourth and final phase is being considered for a sixth tower with 130,000 square feet for office
and retail at the south corner of the development near the intersection of Park Ave N and 757th Ave NE. The phased
development could reach as high as 1.6 million gross square feet. The proposed nine-level development would be built
at the same height and scale as the existing Southport offices with an overall height of approximately 154 feet above
average grade. Parking for 2,207 vehicles would be provided in a shared 4- and 5-level parking garage and 57 spaces are
proposed as on-street parking. In addition, the applicant is proposing to work closely with PSE for the engineering and

capacity needs of the development in order to relocate the powerlines and utility switchgear adjacent to Johns Creek.
Vehicular access to Southport West would be provided by Park Ave N, Lake Washington Blvd N, and the addition of an
internal center road and frontage road.
The site is generally level and consists of gravel yard and asphalt, a Puget Sound Energy switchgear, and an
office/warehouse building. The site contains high seismic hazard areas and the northeast corner of the site contains
Johns Creek and regulated slopes. The soil consists of a loose to medium dense sand, underlain by soft to medium dense
silt, then medium dense to dense sand, very soft silt and clay, and finally dense to very dense silty sand. Groundwater
was observed in the historical exploration at Southport at depths ranging from 3 to 10 feet below existing grade.
Preliminary estimates of cut and fill include approximately 25,000 cubic yards of excavation and 39,200 cubic yards of fill
from an approved source. The depth of excavation is anticipated to not exceed approximately two feet (2’) below ground
level, except for building cores where excavation would be deeper. Stormwater runoff from pollution generating surfaces
would be captured by catch basins and treated in cartridge filter facilities prior to connection into three (3) existing
drainage systems. No significant trees are proposed to be removed. Southport is proposing to plant 115 new trees along
with a variety of shrubs and perennials. The applicant has submitted a Preliminary Geotechnical Report, Technical
Information Report, Traffic Impact Analysis, and Stream Assessment and Final Mitigation Plan with the application.

PROJECT DESCRIPTION: The applicant, Southport West LLC, is requesting Master Plan Review, Hearing Examiner
Site Plan Review and Environmental (SEPA) Review for the construction of Southport West. Southport West is the
completion of the southerly portion of the Southport Development located at the south end of Lake Washington Blvd N.
The proposed expansion of Southport would be located on the 10.09-acre former Puget Sound Energy (PSE) Substation
and PSE utility parcels (APNs 082305-9191 and -9178). The two (2) parcels are located in the Urban Center-2 (UC-2) zone
and the Urban Design District ‘C’. The site is proposed to be developed as five (5) high-rise buildings with approximately
1,200,000 square feet of office and 50,000 of retail development in multiple phases. The proposed first three phases
would be developed as follows: Phase I – Towers 1 and 2 with the garage podium (July 2023 – July 2027), Phase II –
Towers 3 and 4 with garage podium (July 2027 – July 2031), and Phase III – Tower 5 (post July 2031). Phases 1-3 would
start on the south side of the site (closer to Boeing) and would develop to the north side of the lot (closer to Gene Coulon
Memorial Beach Park). A fourth and final phase is being considered for a sixth tower with 130,000 square feet for office
and retail at the south corner of the development near the intersection of Park Ave N and 757th Ave NE. The phased
development could reach as high as 1.6 million gross square feet. The proposed nine-level development would be built
at the same height and scale as the existing Southport offices with an overall height of approximately 154 feet above
average grade. Parking for 2,207 vehicles would be provided in a shared 4- and 5-level parking garage and 57 spaces are
proposed as on-street parking. In addition, the applicant is proposing to work closely with PSE for the engineering and

Vehicular access to Southport West would be provided by Park Ave N, Lake Washington Blvd N, and the addition of an
internal center road and frontage road.
The site is generally level and consists of gravel yard and asphalt, a Puget Sound Energy switchgear, and an
office/warehouse building. The site contains high seismic hazard areas and the northeast corner of the site contains
Johns Creek and regulated slopes. The soil consists of a loose to medium dense sand, underlain by soft to medium dense
silt, then medium dense to dense sand, very soft silt and clay, and finally dense to very dense silty sand. Groundwater
was observed in the historical exploration at Southport at depths ranging from 3 to 10 feet below existing grade.
Preliminary estimates of cut and fill include approximately 25,000 cubic yards of excavation and 39,200 cubic yards of fill
from an approved source. The depth of excavation is anticipated to not exceed approximately two feet (2’) below ground
level, except for building cores where excavation would be deeper. Stormwater runoff from pollution generating surfaces
would be captured by catch basins and treated in cartridge filter facilities prior to connection into three (3) existing

PROJECT DESCRIPTION: The applicant, Southport West LLC, is requesting Master Plan Review, Hearing Examiner
Site Plan Review and Environmental (SEPA) Review for the construction of Southport West. Southport West is the
completion of the southerly portion of the Southport Development located at the south end of Lake Washington Blvd N.
The proposed expansion of Southport would be located on the 10.09-acre former Puget Sound Energy (PSE) Substation
and PSE utility parcels (APNs 082305-9191 and -9178). The two (2) parcels are located in the Urban Center-2 (UC-2) zone
and the Urban Design District ‘C’. The site is proposed to be developed as five (5) high-rise buildings with approximately
1,200,000 square feet of office and 50,000 of retail development in multiple phases. The proposed first three phases
would be developed as follows: Phase I – Towers 1 and 2 with the garage podium (July 2023 – July 2027), Phase II –
Towers 3 and 4 with garage podium (July 2027 – July 2031), and Phase III – Tower 5 (post July 2031). Phases 1-3 would
start on the south side of the site (closer to Boeing) and would develop to the north side of the lot (closer to Gene Coulon
Memorial Beach Park). A fourth and final phase is being considered for a sixth tower with 130,000 square feet for office
and retail at the south corner of the development near the intersection of Park Ave N and 757th Ave NE. The phased
development could reach as high as 1.6 million gross square feet. The proposed nine-level development would be built
at the same height and scale as the existing Southport offices with an overall height of approximately 154 feet above
average grade. Parking for 2,207 vehicles would be provided in a shared 4- and 5-level parking garage and 57 spaces are
proposed as on-street parking. In addition, the applicant is proposing to work closely with PSE for the engineering and

capacity needs of the development in order to relocate the powerlines and utility switchgear adjacent to Johns Creek.
Vehicular access to Southport West would be provided by Park Ave N, Lake Washington Blvd N, and the addition of an
internal center road and frontage road.
The site is generally level and consists of gravel yard and asphalt, a Puget Sound Energy switchgear, and an
office/warehouse building. The site contains high seismic hazard areas and the northeast corner of the site contains
Johns Creek and regulated slopes. The soil consists of a loose to medium dense sand, underlain by soft to medium dense
silt, then medium dense to dense sand, very soft silt and clay, and finally dense to very dense silty sand. Groundwater
was observed in the historical exploration at Southport at depths ranging from 3 to 10 feet below existing grade.
Preliminary estimates of cut and fill include approximately 25,000 cubic yards of excavation and 39,200 cubic yards of fill
from an approved source. The depth of excavation is anticipated to not exceed approximately two feet (2’) below ground
level, except for building cores where excavation would be deeper. Stormwater runoff from pollution generating surfaces
would be captured by catch basins and treated in cartridge filter facilities prior to connection into three (3) existing
drainage systems. No significant trees are proposed to be removed. Southport is proposing to plant 115 new trees along
with a variety of shrubs and perennials. The applicant has submitted a Preliminary Geotechnical Report, Technical
Information Report, Traffic Impact Analysis, and Stream Assessment and Final Mitigation Plan with the application.

capacity needs of the development in order to relocate the powerlines and utility switchgear adjacent to Johns Creek.
Vehicular access to Southport West would be provided by Park Ave N, Lake Washington Blvd N, and the addition of an
internal center road and frontage road.
The site is generally level and consists of gravel yard and asphalt, a Puget Sound Energy switchgear, and an
office/warehouse building. The site contains high seismic hazard areas and the northeast corner of the site contains
Johns Creek and regulated slopes. The soil consists of a loose to medium dense sand, underlain by soft to medium dense
silt, then medium dense to dense sand, very soft silt and clay, and finally dense to very dense silty sand. Groundwater
was observed in the historical exploration at Southport at depths ranging from 3 to 10 feet below existing grade.
Preliminary estimates of cut and fill include approximately 25,000 cubic yards of excavation and 39,200 cubic yards of fill
from an approved source. The depth of excavation is anticipated to not exceed approximately two feet (2’) below ground
level, except for building cores where excavation would be deeper. Stormwater runoff from pollution generating surfaces
would be captured by catch basins and treated in cartridge filter facilities prior to connection into three (3) existing
drainage systems. No significant trees are proposed to be removed. Southport is proposing to plant 115 new trees along
with a variety of shrubs and perennials. The applicant has submitted a Preliminary Geotechnical Report, Technical
Information Report, Traffic Impact Analysis, and Stream Assessment and Final Mitigation Plan with the application.

PROJECT DESCRIPTION: The applicant, Southport West LLC, is requesting Master Plan Review, Hearing Examiner
Site Plan Review and Environmental (SEPA) Review for the construction of Southport West. Southport West is the
completion of the southerly portion of the Southport Development located at the south end of Lake Washington Blvd N.
The proposed expansion of Southport would be located on the 10.09-acre former Puget Sound Energy (PSE) Substation
and PSE utility parcels (APNs 082305-9191 and -9178). The two (2) parcels are located in the Urban Center-2 (UC-2) zone
and the Urban Design District ‘C’. The site is proposed to be developed as five (5) high-rise buildings with approximately
1,200,000 square feet of office and 50,000 of retail development in multiple phases. The proposed first three phases
would be developed as follows: Phase I – Towers 1 and 2 with the garage podium (July 2023 – July 2027), Phase II –
Towers 3 and 4 with garage podium (July 2027 – July 2031), and Phase III – Tower 5 (post July 2031). Phases 1-3 would
start on the south side of the site (closer to Boeing) and would develop to the north side of the lot (closer to Gene Coulon
Memorial Beach Park). A fourth and final phase is being considered for a sixth tower with 130,000 square feet for office
and retail at the south corner of the development near the intersection of Park Ave N and 757th Ave NE. The phased
development could reach as high as 1.6 million gross square feet. The proposed nine-level development would be built
at the same height and scale as the existing Southport offices with an overall height of approximately 154 feet above
average grade. Parking for 2,207 vehicles would be provided in a shared 4- and 5-level parking garage and 57 spaces are
proposed as on-street parking. In addition, the applicant is proposing to work closely with PSE for the engineering and

PROJECT DESCRIPTION: The applicant, Southport West LLC, is requesting Master Plan Review, Hearing Examiner
Site Plan Review and Environmental (SEPA) Review for the construction of Southport West. Southport West is the
completion of the southerly portion of the Southport Development located at the south end of Lake Washington Blvd N.
The proposed expansion of Southport would be located on the 10.09-acre former Puget Sound Energy (PSE) Substation
and PSE utility parcels (APNs 082305-9191 and -9178). The two (2) parcels are located in the Urban Center-2 (UC-2) zone
and the Urban Design District ‘C’. The site is proposed to be developed as five (5) high-rise buildings with approximately
1,200,000 square feet of office and 50,000 of retail development in multiple phases. The proposed first three phases
would be developed as follows: Phase I – Towers 1 and 2 with the garage podium (July 2023 – July 2027), Phase II –
Towers 3 and 4 with garage podium (July 2027 – July 2031), and Phase III – Tower 5 (post July 2031). Phases 1-3 would
start on the south side of the site (closer to Boeing) and would develop to the north side of the lot (closer to Gene Coulon
Memorial Beach Park). A fourth and final phase is being considered for a sixth tower with 130,000 square feet for office
and retail at the south corner of the development near the intersection of Park Ave N and 757th Ave NE. The phased
development could reach as high as 1.6 million gross square feet. The proposed nine-level development would be built
at the same height and scale as the existing Southport offices with an overall height of approximately 154 feet above
average grade. Parking for 2,207 vehicles would be provided in a shared 4- and 5-level parking garage and 57 spaces are
proposed as on-street parking. In addition, the applicant is proposing to work closely with PSE for the engineering and

capacity needs of the development in order to relocate the powerlines and utility switchgear adjacent to Johns Creek.
Vehicular access to Southport West would be provided by Park Ave N, Lake Washington Blvd N, and the addition of an
internal center road and frontage road.
The site is generally level and consists of gravel yard and asphalt, a Puget Sound Energy switchgear, and an
office/warehouse building. The site contains high seismic hazard areas and the northeast corner of the site contains
Johns Creek and regulated slopes. The soil consists of a loose to medium dense sand, underlain by soft to medium dense
silt, then medium dense to dense sand, very soft silt and clay, and finally dense to very dense silty sand. Groundwater
was observed in the historical exploration at Southport at depths ranging from 3 to 10 feet below existing grade.
Preliminary estimates of cut and fill include approximately 25,000 cubic yards of excavation and 39,200 cubic yards of fill
from an approved source. The depth of excavation is anticipated to not exceed approximately two feet (2’) below ground
level, except for building cores where excavation would be deeper. Stormwater runoff from pollution generating surfaces
would be captured by catch basins and treated in cartridge filter facilities prior to connection into three (3) existing
drainage systems. No significant trees are proposed to be removed. Southport is proposing to plant 115 new trees along
with a variety of shrubs and perennials. The applicant has submitted a Preliminary Geotechnical Report, Technical
Information Report, Traffic Impact Analysis, and Stream Assessment and Final Mitigation Plan with the application.

Towers 3 and 4 with garage podium (July 2027 – July 2031), and Phase III – Tower 5 (post July 2031). Phases 1-3 would
start on the south side of the site (closer to Boeing) and would develop to the north side of the lot (closer to Gene Coulon
Memorial Beach Park). A fourth and final phase is being considered for a sixth tower with 130,000 square feet for office
and retail at the south corner of the development near the intersection of Park Ave N and 757th Ave NE. The phased
development could reach as high as 1.6 million gross square feet. The proposed nine-level development would be built
at the same height and scale as the existing Southport offices with an overall height of approximately 154 feet above
average grade. Parking for 2,207 vehicles would be provided in a shared 4- and 5-level parking garage and 57 spaces are
proposed as on-street parking. In addition, the applicant is proposing to work closely with PSE for the engineering and

Vehicular access to Southport West would be provided by Park Ave N, Lake Washington Blvd N, and the addition of an
internal center road and frontage road.
The site is generally level and consists of gravel yard and asphalt, a Puget Sound Energy switchgear, and an
office/warehouse building. The site contains high seismic hazard areas and the northeast corner of the site contains
Johns Creek and regulated slopes. The soil consists of a loose to medium dense sand, underlain by soft to medium dense
silt, then medium dense to dense sand, very soft silt and clay, and finally dense to very dense silty sand. Groundwater
was observed in the historical exploration at Southport at depths ranging from 3 to 10 feet below existing grade.
Preliminary estimates of cut and fill include approximately 25,000 cubic yards of excavation and 39,200 cubic yards of fill
from an approved source. The depth of excavation is anticipated to not exceed approximately two feet (2’) below ground
level, except for building cores where excavation would be deeper. Stormwater runoff from pollution generating surfaces
would be captured by catch basins and treated in cartridge filter facilities prior to connection into three (3) existing
drainage systems. No significant trees are proposed to be removed. Southport is proposing to plant 115 new trees along
with a variety of shrubs and perennials. The applicant has submitted a Preliminary Geotechnical Report, Technical
Information Report, Traffic Impact Analysis, and Stream Assessment and Final Mitigation Plan with the application.

PROJECT DESCRIPTION: The applicant, Southport West LLC, is requesting Master Plan Review, Hearing Examiner
Site Plan Review and Environmental (SEPA) Review for the construction of Southport West. Southport West is the
completion of the southerly portion of the Southport Development located at the south end of Lake Washington Blvd N.
The proposed expansion of Southport would be located on the 10.09-acre former Puget Sound Energy (PSE) Substation
and PSE utility parcels (APNs 082305-9191 and -9178). The two (2) parcels are located in the Urban Center-2 (UC-2) zone
and the Urban Design District ‘C’. The site is proposed to be developed as five (5) high-rise buildings with approximately
1,200,000 square feet of office and 50,000 of retail development in multiple phases. The proposed first three phases
would be developed as follows: Phase I – Towers 1 and 2 with the garage podium (July 2023 – July 2027), Phase II –
Towers 3 and 4 with garage podium (July 2027 – July 2031), and Phase III – Tower 5 (post July 2031). Phases 1-3 would
start on the south side of the site (closer to Boeing) and would develop to the north side of the lot (closer to Gene Coulon
Memorial Beach Park). A fourth and final phase is being considered for a sixth tower with 130,000 square feet for office
and retail at the south corner of the development near the intersection of Park Ave N and 757th Ave NE. The phased
development could reach as high as 1.6 million gross square feet. The proposed nine-level development would be built
at the same height and scale as the existing Southport offices with an overall height of approximately 154 feet above
average grade. Parking for 2,207 vehicles would be provided in a shared 4- and 5-level parking garage and 57 spaces are
proposed as on-street parking. In addition, the applicant is proposing to work closely with PSE for the engineering and

capacity needs of the development in order to relocate the powerlines and utility switchgear adjacent to Johns Creek.
Vehicular access to Southport West would be provided by Park Ave N, Lake Washington Blvd N, and the addition of an
internal center road and frontage road.
The site is generally level and consists of gravel yard and asphalt, a Puget Sound Energy switchgear, and an
office/warehouse building. The site contains high seismic hazard areas and the northeast corner of the site contains
Johns Creek and regulated slopes. The soil consists of a loose to medium dense sand, underlain by soft to medium dense
silt, then medium dense to dense sand, very soft silt and clay, and finally dense to very dense silty sand. Groundwater
was observed in the historical exploration at Southport at depths ranging from 3 to 10 feet below existing grade.
Preliminary estimates of cut and fill include approximately 25,000 cubic yards of excavation and 39,200 cubic yards of fill
from an approved source. The depth of excavation is anticipated to not exceed approximately two feet (2’) below ground
level, except for building cores where excavation would be deeper. Stormwater runoff from pollution generating surfaces
would be captured by catch basins and treated in cartridge filter facilities prior to connection into three (3) existing
drainage systems. No significant trees are proposed to be removed. Southport is proposing to plant 115 new trees along
with a variety of shrubs and perennials. The applicant has submitted a Preliminary Geotechnical Report, Technical
Information Report, Traffic Impact Analysis, and Stream Assessment and Final Mitigation Plan with the application.

PROJECT DESCRIPTION: The applicant, Southport West LLC, is requesting Master Plan Review, Hearing Examiner
Site Plan Review and Environmental (SEPA) Review for the construction of Southport West. Southport West is the
completion of the southerly portion of the Southport Development located at the south end of Lake Washington Blvd N.
The proposed expansion of Southport would be located on the 10.09-acre former Puget Sound Energy (PSE) Substation
and PSE utility parcels (APNs 082305-9191 and -9178). The two (2) parcels are located in the Urban Center-2 (UC-2) zone
and the Urban Design District ‘C’. The site is proposed to be developed as five (5) high-rise buildings with approximately
1,200,000 square feet of office and 50,000 of retail development in multiple phases. The proposed first three phases
would be developed as follows: Phase I – Towers 1 and 2 with the garage podium (July 2023 – July 2027), Phase II –
Towers 3 and 4 with garage podium (July 2027 – July 2031), and Phase III – Tower 5 (post July 2031). Phases 1-3 would
start on the south side of the site (closer to Boeing) and would develop to the north side of the lot (closer to Gene Coulon
Memorial Beach Park). A fourth and final phase is being considered for a sixth tower with 130,000 square feet for office
and retail at the south corner of the development near the intersection of Park Ave N and 757th Ave NE. The phased
development could reach as high as 1.6 million gross square feet. The proposed nine-level development would be built
at the same height and scale as the existing Southport offices with an overall height of approximately 154 feet above
average grade. Parking for 2,207 vehicles would be provided in a shared 4- and 5-level parking garage and 57 spaces are
proposed as on-street parking. In addition, the applicant is proposing to work closely with PSE for the engineering and

capacity needs of the development in order to relocate the powerlines and utility switchgear adjacent to Johns Creek.
Vehicular access to Southport West would be provided by Park Ave N, Lake Washington Blvd N, and the addition of an
internal center road and frontage road.
The site is generally level and consists of gravel yard and asphalt, a Puget Sound Energy switchgear, and an
office/warehouse building. The site contains high seismic hazard areas and the northeast corner of the site contains
Johns Creek and regulated slopes. The soil consists of a loose to medium dense sand, underlain by soft to medium dense
silt, then medium dense to dense sand, very soft silt and clay, and finally dense to very dense silty sand. Groundwater
was observed in the historical exploration at Southport at depths ranging from 3 to 10 feet below existing grade.
Preliminary estimates of cut and fill include approximately 25,000 cubic yards of excavation and 39,200 cubic yards of fill
from an approved source. The depth of excavation is anticipated to not exceed approximately two feet (2’) below ground
level, except for building cores where excavation would be deeper. Stormwater runoff from pollution generating surfaces
would be captured by catch basins and treated in cartridge filter facilities prior to connection into three (3) existing
drainage systems. No significant trees are proposed to be removed. Southport is proposing to plant 115 new trees along
with a variety of shrubs and perennials. The applicant has submitted a Preliminary Geotechnical Report, Technical
Information Report, Traffic Impact Analysis, and Stream Assessment and Final Mitigation Plan with the application.

office/warehouse building. The site contains high seismic hazard areas and the northeast corner of the site contains
Johns Creek and regulated slopes. The soil consists of a loose to medium dense sand, underlain by soft to medium dense
silt, then medium dense to dense sand, very soft silt and clay, and finally dense to very dense silty sand. Groundwater
was observed in the historical exploration at Southport at depths ranging from 3 to 10 feet below existing grade.
Preliminary estimates of cut and fill include approximately 25,000 cubic yards of excavation and 39,200 cubic yards of fill
from an approved source. The depth of excavation is anticipated to not exceed approximately two feet (2’) below ground
level, except for building cores where excavation would be deeper. Stormwater runoff from pollution generating surfaces
would be captured by catch basins and treated in cartridge filter facilities prior to connection into three (3) existing
drainage systems. No significant trees are proposed to be removed. Southport is proposing to plant 115 new trees along
with a variety of shrubs and perennials. The applicant has submitted a Preliminary Geotechnical Report, Technical
Information Report, Traffic Impact Analysis, and Stream Assessment and Final Mitigation Plan with the application.

Site Plan Review and Environmental (SEPA) Review for the construction of Southport West. Southport West is the
completion of the southerly portion of the Southport Development located at the south end of Lake Washington Blvd N.
The proposed expansion of Southport would be located on the 10.09-acre former Puget Sound Energy (PSE) Substation
and PSE utility parcels (APNs 082305-9191 and -9178). The two (2) parcels are located in the Urban Center-2 (UC-2) zone
and the Urban Design District ‘C’. The site is proposed to be developed as five (5) high-rise buildings with approximately
1,200,000 square feet of office and 50,000 of retail development in multiple phases. The proposed first three phases
would be developed as follows: Phase I – Towers 1 and 2 with the garage podium (July 2023 – July 2027), Phase II –
Towers 3 and 4 with garage podium (July 2027 – July 2031), and Phase III – Tower 5 (post July 2031). Phases 1-3 would
start on the south side of the site (closer to Boeing) and would develop to the north side of the lot (closer to Gene Coulon
Memorial Beach Park). A fourth and final phase is being considered for a sixth tower with 130,000 square feet for office
and retail at the south corner of the development near the intersection of Park Ave N and 757th Ave NE. The phased
development could reach as high as 1.6 million gross square feet. The proposed nine-level development would be built
at the same height and scale as the existing Southport offices with an overall height of approximately 154 feet above
average grade. Parking for 2,207 vehicles would be provided in a shared 4- and 5-level parking garage and 57 spaces are
proposed as on-street parking. In addition, the applicant is proposing to work closely with PSE for the engineering and

PROJECT DESCRIPTION: The applicant, Southport West LLC, is requesting Master Plan Review, Hearing Examiner
Site Plan Review and Environmental (SEPA) Review for the construction of Southport West. Southport West is the
completion of the southerly portion of the Southport Development located at the south end of Lake Washington Blvd N.
The proposed expansion of Southport would be located on the 10.09-acre former Puget Sound Energy (PSE) Substation
and PSE utility parcels (APNs 082305-9191 and -9178). The two (2) parcels are located in the Urban Center-2 (UC-2) zone
and the Urban Design District ‘C’. The site is proposed to be developed as five (5) high-rise buildings with approximately
1,200,000 square feet of office and 50,000 of retail development in multiple phases. The proposed first three phases
would be developed as follows: Phase I – Towers 1 and 2 with the garage podium (July 2023 – July 2027), Phase II –
Towers 3 and 4 with garage podium (July 2027 – July 2031), and Phase III – Tower 5 (post July 2031). Phases 1-3 would
start on the south side of the site (closer to Boeing) and would develop to the north side of the lot (closer to Gene Coulon
Memorial Beach Park). A fourth and final phase is being considered for a sixth tower with 130,000 square feet for office
and retail at the south corner of the development near the intersection of Park Ave N and 757th Ave NE. The phased
development could reach as high as 1.6 million gross square feet. The proposed nine-level development would be built
at the same height and scale as the existing Southport offices with an overall height of approximately 154 feet above
average grade. Parking for 2,207 vehicles would be provided in a shared 4- and 5-level parking garage and 57 spaces are
proposed as on-street parking. In addition, the applicant is proposing to work closely with PSE for the engineering and

capacity needs of the development in order to relocate the powerlines and utility switchgear adjacent to Johns Creek.
Vehicular access to Southport West would be provided by Park Ave N, Lake Washington Blvd N, and the addition of an
internal center road and frontage road.
The site is generally level and consists of gravel yard and asphalt, a Puget Sound Energy switchgear, and an
office/warehouse building. The site contains high seismic hazard areas and the northeast corner of the site contains
Johns Creek and regulated slopes. The soil consists of a loose to medium dense sand, underlain by soft to medium dense
silt, then medium dense to dense sand, very soft silt and clay, and finally dense to very dense silty sand. Groundwater
was observed in the historical exploration at Southport at depths ranging from 3 to 10 feet below existing grade.
Preliminary estimates of cut and fill include approximately 25,000 cubic yards of excavation and 39,200 cubic yards of fill
from an approved source. The depth of excavation is anticipated to not exceed approximately two feet (2’) below ground
level, except for building cores where excavation would be deeper. Stormwater runoff from pollution generating surfaces
would be captured by catch basins and treated in cartridge filter facilities prior to connection into three (3) existing
drainage systems. No significant trees are proposed to be removed. Southport is proposing to plant 115 new trees along
with a variety of shrubs and perennials. The applicant has submitted a Preliminary Geotechnical Report, Technical
Information Report, Traffic Impact Analysis, and Stream Assessment and Final Mitigation Plan with the application.

capacity needs of the development in order to relocate the powerlines and utility switchgear adjacent to Johns Creek.
Vehicular access to Southport West would be provided by Park Ave N, Lake Washington Blvd N, and the addition of an
internal center road and frontage road.
The site is generally level and consists of gravel yard and asphalt, a Puget Sound Energy switchgear, and an
office/warehouse building. The site contains high seismic hazard areas and the northeast corner of the site contains
Johns Creek and regulated slopes. The soil consists of a loose to medium dense sand, underlain by soft to medium dense
silt, then medium dense to dense sand, very soft silt and clay, and finally dense to very dense silty sand. Groundwater
was observed in the historical exploration at Southport at depths ranging from 3 to 10 feet below existing grade.
Preliminary estimates of cut and fill include approximately 25,000 cubic yards of excavation and 39,200 cubic yards of fill
from an approved source. The depth of excavation is anticipated to not exceed approximately two feet (2’) below ground
level, except for building cores where excavation would be deeper. Stormwater runoff from pollution generating surfaces
would be captured by catch basins and treated in cartridge filter facilities prior to connection into three (3) existing
drainage systems. No significant trees are proposed to be removed. Southport is proposing to plant 115 new trees along
with a variety of shrubs and perennials. The applicant has submitted a Preliminary Geotechnical Report, Technical
Information Report, Traffic Impact Analysis, and Stream Assessment and Final Mitigation Plan with the application.

The proposed expansion of Southport would be located on the 10.09-acre former Puget Sound Energy (PSE) Substation
and PSE utility parcels (APNs 082305-9191 and -9178). The two (2) parcels are located in the Urban Center-2 (UC-2) zone
and the Urban Design District ‘C’. The site is proposed to be developed as five (5) high-rise buildings with approximately
1,200,000 square feet of office and 50,000 of retail development in multiple phases. The proposed first three phases
would be developed as follows: Phase I – Towers 1 and 2 with the garage podium (July 2023 – July 2027), Phase II –
Towers 3 and 4 with garage podium (July 2027 – July 2031), and Phase III – Tower 5 (post July 2031). Phases 1-3 would
start on the south side of the site (closer to Boeing) and would develop to the north side of the lot (closer to Gene Coulon
Memorial Beach Park). A fourth and final phase is being considered for a sixth tower with 130,000 square feet for office
and retail at the south corner of the development near the intersection of Park Ave N and 757th Ave NE. The phased
development could reach as high as 1.6 million gross square feet. The proposed nine-level development would be built
at the same height and scale as the existing Southport offices with an overall height of approximately 154 feet above
average grade. Parking for 2,207 vehicles would be provided in a shared 4- and 5-level parking garage and 57 spaces are

PROJECT DESCRIPTION: The applicant, Southport West LLC, is requesting Master Plan Review, Hearing Examiner
Site Plan Review and Environmental (SEPA) Review for the construction of Southport West. Southport West is the
completion of the southerly portion of the Southport Development located at the south end of Lake Washington Blvd N.
The proposed expansion of Southport would be located on the 10.09-acre former Puget Sound Energy (PSE) Substation
and PSE utility parcels (APNs 082305-9191 and -9178). The two (2) parcels are located in the Urban Center-2 (UC-2) zone
and the Urban Design District ‘C’. The site is proposed to be developed as five (5) high-rise buildings with approximately
1,200,000 square feet of office and 50,000 of retail development in multiple phases. The proposed first three phases
would be developed as follows: Phase I – Towers 1 and 2 with the garage podium (July 2023 – July 2027), Phase II –
Towers 3 and 4 with garage podium (July 2027 – July 2031), and Phase III – Tower 5 (post July 2031). Phases 1-3 would
start on the south side of the site (closer to Boeing) and would develop to the north side of the lot (closer to Gene Coulon
Memorial Beach Park). A fourth and final phase is being considered for a sixth tower with 130,000 square feet for office
and retail at the south corner of the development near the intersection of Park Ave N and 757th Ave NE. The phased
development could reach as high as 1.6 million gross square feet. The proposed nine-level development would be built
at the same height and scale as the existing Southport offices with an overall height of approximately 154 feet above
average grade. Parking for 2,207 vehicles would be provided in a shared 4- and 5-level parking garage and 57 spaces are
proposed as on-street parking. In addition, the applicant is proposing to work closely with PSE for the engineering and

capacity needs of the development in order to relocate the powerlines and utility switchgear adjacent to Johns Creek.
Vehicular access to Southport West would be provided by Park Ave N, Lake Washington Blvd N, and the addition of an
internal center road and frontage road.
The site is generally level and consists of gravel yard and asphalt, a Puget Sound Energy switchgear, and an
office/warehouse building. The site contains high seismic hazard areas and the northeast corner of the site contains
Johns Creek and regulated slopes. The soil consists of a loose to medium dense sand, underlain by soft to medium dense
silt, then medium dense to dense sand, very soft silt and clay, and finally dense to very dense silty sand. Groundwater
was observed in the historical exploration at Southport at depths ranging from 3 to 10 feet below existing grade.
Preliminary estimates of cut and fill include approximately 25,000 cubic yards of excavation and 39,200 cubic yards of fill
from an approved source. The depth of excavation is anticipated to not exceed approximately two feet (2’) below ground
level, except for building cores where excavation would be deeper. Stormwater runoff from pollution generating surfaces
would be captured by catch basins and treated in cartridge filter facilities prior to connection into three (3) existing
drainage systems. No significant trees are proposed to be removed. Southport is proposing to plant 115 new trees along
with a variety of shrubs and perennials. The applicant has submitted a Preliminary Geotechnical Report, Technical
Information Report, Traffic Impact Analysis, and Stream Assessment and Final Mitigation Plan with the application.

and PSE utility parcels (APNs 082305-9191 and -9178). The two (2) parcels are located in the Urban Center-2 (UC-2) zone
and the Urban Design District ‘C’. The site is proposed to be developed as five (5) high-rise buildings with approximately
1,200,000 square feet of office and 50,000 of retail development in multiple phases. The proposed first three phases
would be developed as follows: Phase I – Towers 1 and 2 with the garage podium (July 2023 – July 2027), Phase II –
Towers 3 and 4 with garage podium (July 2027 – July 2031), and Phase III – Tower 5 (post July 2031). Phases 1-3 would
start on the south side of the site (closer to Boeing) and would develop to the north side of the lot (closer to Gene Coulon
Memorial Beach Park). A fourth and final phase is being considered for a sixth tower with 130,000 square feet for office
and retail at the south corner of the development near the intersection of Park Ave N and 757th Ave NE. The phased
development could reach as high as 1.6 million gross square feet. The proposed nine-level development would be built
at the same height and scale as the existing Southport offices with an overall height of approximately 154 feet above
average grade. Parking for 2,207 vehicles would be provided in a shared 4- and 5-level parking garage and 57 spaces are
proposed as on-street parking. In addition, the applicant is proposing to work closely with PSE for the engineering and

capacity needs of the development in order to relocate the powerlines and utility switchgear adjacent to Johns Creek.
Vehicular access to Southport West would be provided by Park Ave N, Lake Washington Blvd N, and the addition of an
internal center road and frontage road.
The site is generally level and consists of gravel yard and asphalt, a Puget Sound Energy switchgear, and an
office/warehouse building. The site contains high seismic hazard areas and the northeast corner of the site contains
Johns Creek and regulated slopes. The soil consists of a loose to medium dense sand, underlain by soft to medium dense
silt, then medium dense to dense sand, very soft silt and clay, and finally dense to very dense silty sand. Groundwater
was observed in the historical exploration at Southport at depths ranging from 3 to 10 feet below existing grade.
Preliminary estimates of cut and fill include approximately 25,000 cubic yards of excavation and 39,200 cubic yards of fill
from an approved source. The depth of excavation is anticipated to not exceed approximately two feet (2’) below ground
level, except for building cores where excavation would be deeper. Stormwater runoff from pollution generating surfaces
would be captured by catch basins and treated in cartridge filter facilities prior to connection into three (3) existing
drainage systems. No significant trees are proposed to be removed. Southport is proposing to plant 115 new trees along
with a variety of shrubs and perennials. The applicant has submitted a Preliminary Geotechnical Report, Technical
Information Report, Traffic Impact Analysis, and Stream Assessment and Final Mitigation Plan with the application.

PROJECT DESCRIPTION: The applicant, Southport West LLC, is requesting Master Plan Review, Hearing Examiner
Site Plan Review and Environmental (SEPA) Review for the construction of Southport West. Southport West is the
completion of the southerly portion of the Southport Development located at the south end of Lake Washington Blvd N.
The proposed expansion of Southport would be located on the 10.09-acre former Puget Sound Energy (PSE) Substation
and PSE utility parcels (APNs 082305-9191 and -9178). The two (2) parcels are located in the Urban Center-2 (UC-2) zone
and the Urban Design District ‘C’. The site is proposed to be developed as five (5) high-rise buildings with approximately
1,200,000 square feet of office and 50,000 of retail development in multiple phases. The proposed first three phases
would be developed as follows: Phase I – Towers 1 and 2 with the garage podium (July 2023 – July 2027), Phase II –
Towers 3 and 4 with garage podium (July 2027 – July 2031), and Phase III – Tower 5 (post July 2031). Phases 1-3 would
start on the south side of the site (closer to Boeing) and would develop to the north side of the lot (closer to Gene Coulon
Memorial Beach Park). A fourth and final phase is being considered for a sixth tower with 130,000 square feet for office
and retail at the south corner of the development near the intersection of Park Ave N and 757th Ave NE. The phased
development could reach as high as 1.6 million gross square feet. The proposed nine-level development would be built
at the same height and scale as the existing Southport offices with an overall height of approximately 154 feet above
average grade. Parking for 2,207 vehicles would be provided in a shared 4- and 5-level parking garage and 57 spaces are
proposed as on-street parking. In addition, the applicant is proposing to work closely with PSE for the engineering and

Vehicular access to Southport West would be provided by Park Ave N, Lake Washington Blvd N, and the addition of an
internal center road and frontage road.
The site is generally level and consists of gravel yard and asphalt, a Puget Sound Energy switchgear, and an
office/warehouse building. The site contains high seismic hazard areas and the northeast corner of the site contains
Johns Creek and regulated slopes. The soil consists of a loose to medium dense sand, underlain by soft to medium dense
silt, then medium dense to dense sand, very soft silt and clay, and finally dense to very dense silty sand. Groundwater
was observed in the historical exploration at Southport at depths ranging from 3 to 10 feet below existing grade.
Preliminary estimates of cut and fill include approximately 25,000 cubic yards of excavation and 39,200 cubic yards of fill
from an approved source. The depth of excavation is anticipated to not exceed approximately two feet (2’) below ground
level, except for building cores where excavation would be deeper. Stormwater runoff from pollution generating surfaces
would be captured by catch basins and treated in cartridge filter facilities prior to connection into three (3) existing
drainage systems. No significant trees are proposed to be removed. Southport is proposing to plant 115 new trees along
with a variety of shrubs and perennials. The applicant has submitted a Preliminary Geotechnical Report, Technical
Information Report, Traffic Impact Analysis, and Stream Assessment and Final Mitigation Plan with the application.

PROJECT DESCRIPTION: The applicant, Southport West LLC, is requesting Master Plan Review, Hearing Examiner
Site Plan Review and Environmental (SEPA) Review for the construction of Southport West. Southport West is the
completion of the southerly portion of the Southport Development located at the south end of Lake Washington Blvd N.
The proposed expansion of Southport would be located on the 10.09-acre former Puget Sound Energy (PSE) Substation
and PSE utility parcels (APNs 082305-9191 and -9178). The two (2) parcels are located in the Urban Center-2 (UC-2) zone
and the Urban Design District ‘C’. The site is proposed to be developed as five (5) high-rise buildings with approximately
1,200,000 square feet of office and 50,000 of retail development in multiple phases. The proposed first three phases
would be developed as follows: Phase I – Towers 1 and 2 with the garage podium (July 2023 – July 2027), Phase II –
Towers 3 and 4 with garage podium (July 2027 – July 2031), and Phase III – Tower 5 (post July 2031). Phases 1-3 would
start on the south side of the site (closer to Boeing) and would develop to the north side of the lot (closer to Gene Coulon
Memorial Beach Park). A fourth and final phase is being considered for a sixth tower with 130,000 square feet for office
and retail at the south corner of the development near the intersection of Park Ave N and 757th Ave NE. The phased
development could reach as high as 1.6 million gross square feet. The proposed nine-level development would be built
at the same height and scale as the existing Southport offices with an overall height of approximately 154 feet above
average grade. Parking for 2,207 vehicles would be provided in a shared 4- and 5-level parking garage and 57 spaces are
proposed as on-street parking. In addition, the applicant is proposing to work closely with PSE for the engineering and

capacity needs of the development in order to relocate the powerlines and utility switchgear adjacent to Johns Creek.
Vehicular access to Southport West would be provided by Park Ave N, Lake Washington Blvd N, and the addition of an
internal center road and frontage road.
The site is generally level and consists of gravel yard and asphalt, a Puget Sound Energy switchgear, and an
office/warehouse building. The site contains high seismic hazard areas and the northeast corner of the site contains
Johns Creek and regulated slopes. The soil consists of a loose to medium dense sand, underlain by soft to medium dense
silt, then medium dense to dense sand, very soft silt and clay, and finally dense to very dense silty sand. Groundwater
was observed in the historical exploration at Southport at depths ranging from 3 to 10 feet below existing grade.
Preliminary estimates of cut and fill include approximately 25,000 cubic yards of excavation and 39,200 cubic yards of fill
from an approved source. The depth of excavation is anticipated to not exceed approximately two feet (2’) below ground
level, except for building cores where excavation would be deeper. Stormwater runoff from pollution generating surfaces
would be captured by catch basins and treated in cartridge filter facilities prior to connection into three (3) existing
drainage systems. No significant trees are proposed to be removed. Southport is proposing to plant 115 new trees along
with a variety of shrubs and perennials. The applicant has submitted a Preliminary Geotechnical Report, Technical
Information Report, Traffic Impact Analysis, and Stream Assessment and Final Mitigation Plan with the application.

capacity needs of the development in order to relocate the powerlines and utility switchgear adjacent to Johns Creek.
Vehicular access to Southport West would be provided by Park Ave N, Lake Washington Blvd N, and the addition of an
internal center road and frontage road.
The site is generally level and consists of gravel yard and asphalt, a Puget Sound Energy switchgear, and an
office/warehouse building. The site contains high seismic hazard areas and the northeast corner of the site contains
Johns Creek and regulated slopes. The soil consists of a loose to medium dense sand, underlain by soft to medium dense
silt, then medium dense to dense sand, very soft silt and clay, and finally dense to very dense silty sand. Groundwater
was observed in the historical exploration at Southport at depths ranging from 3 to 10 feet below existing grade.
Preliminary estimates of cut and fill include approximately 25,000 cubic yards of excavation and 39,200 cubic yards of fill
from an approved source. The depth of excavation is anticipated to not exceed approximately two feet (2’) below ground
level, except for building cores where excavation would be deeper. Stormwater runoff from pollution generating surfaces
would be captured by catch basins and treated in cartridge filter facilities prior to connection into three (3) existing
drainage systems. No significant trees are proposed to be removed. Southport is proposing to plant 115 new trees along
with a variety of shrubs and perennials. The applicant has submitted a Preliminary Geotechnical Report, Technical
Information Report, Traffic Impact Analysis, and Stream Assessment and Final Mitigation Plan with the application.

Site Plan Review and Environmental (SEPA) Review for the construction of Southport West. Southport West is the
completion of the southerly portion of the Southport Development located at the south end of Lake Washington Blvd N.
The proposed expansion of Southport would be located on the 10.09-acre former Puget Sound Energy (PSE) Substation
and PSE utility parcels (APNs 082305-9191 and -9178). The two (2) parcels are located in the Urban Center-2 (UC-2) zone
and the Urban Design District ‘C’. The site is proposed to be developed as five (5) high-rise buildings with approximately
1,200,000 square feet of office and 50,000 of retail development in multiple phases. The proposed first three phases
would be developed as follows: Phase I – Towers 1 and 2 with the garage podium (July 2023 – July 2027), Phase II –
Towers 3 and 4 with garage podium (July 2027 – July 2031), and Phase III – Tower 5 (post July 2031). Phases 1-3 would
start on the south side of the site (closer to Boeing) and would develop to the north side of the lot (closer to Gene Coulon
Memorial Beach Park). A fourth and final phase is being considered for a sixth tower with 130,000 square feet for office
and retail at the south corner of the development near the intersection of Park Ave N and 757th Ave NE. The phased
development could reach as high as 1.6 million gross square feet. The proposed nine-level development would be built
at the same height and scale as the existing Southport offices with an overall height of approximately 154 feet above
average grade. Parking for 2,207 vehicles would be provided in a shared 4- and 5-level parking garage and 57 spaces are
proposed as on-street parking. In addition, the applicant is proposing to work closely with PSE for the engineering and

PROJECT DESCRIPTION: The applicant, Southport West LLC, is requesting Master Plan Review, Hearing Examiner
Site Plan Review and Environmental (SEPA) Review for the construction of Southport West. Southport West is the
completion of the southerly portion of the Southport Development located at the south end of Lake Washington Blvd N.
The proposed expansion of Southport would be located on the 10.09-acre former Puget Sound Energy (PSE) Substation
and PSE utility parcels (APNs 082305-9191 and -9178). The two (2) parcels are located in the Urban Center-2 (UC-2) zone
and the Urban Design District ‘C’. The site is proposed to be developed as five (5) high-rise buildings with approximately
1,200,000 square feet of office and 50,000 of retail development in multiple phases. The proposed first three phases
would be developed as follows: Phase I – Towers 1 and 2 with the garage podium (July 2023 – July 2027), Phase II –
Towers 3 and 4 with garage podium (July 2027 – July 2031), and Phase III – Tower 5 (post July 2031). Phases 1-3 would
start on the south side of the site (closer to Boeing) and would develop to the north side of the lot (closer to Gene Coulon
Memorial Beach Park). A fourth and final phase is being considered for a sixth tower with 130,000 square feet for office
and retail at the south corner of the development near the intersection of Park Ave N and 757th Ave NE. The phased
development could reach as high as 1.6 million gross square feet. The proposed nine-level development would be built
at the same height and scale as the existing Southport offices with an overall height of approximately 154 feet above
average grade. Parking for 2,207 vehicles would be provided in a shared 4- and 5-level parking garage and 57 spaces are
proposed as on-street parking. In addition, the applicant is proposing to work closely with PSE for the engineering and

capacity needs of the development in order to relocate the powerlines and utility switchgear adjacent to Johns Creek.
Vehicular access to Southport West would be provided by Park Ave N, Lake Washington Blvd N, and the addition of an
internal center road and frontage road.
The site is generally level and consists of gravel yard and asphalt, a Puget Sound Energy switchgear, and an
office/warehouse building. The site contains high seismic hazard areas and the northeast corner of the site contains
Johns Creek and regulated slopes. The soil consists of a loose to medium dense sand, underlain by soft to medium dense
silt, then medium dense to dense sand, very soft silt and clay, and finally dense to very dense silty sand. Groundwater
was observed in the historical exploration at Southport at depths ranging from 3 to 10 feet below existing grade.
Preliminary estimates of cut and fill include approximately 25,000 cubic yards of excavation and 39,200 cubic yards of fill
from an approved source. The depth of excavation is anticipated to not exceed approximately two feet (2’) below ground
level, except for building cores where excavation would be deeper. Stormwater runoff from pollution generating surfaces
would be captured by catch basins and treated in cartridge filter facilities prior to connection into three (3) existing
drainage systems. No significant trees are proposed to be removed. Southport is proposing to plant 115 new trees along
with a variety of shrubs and perennials. The applicant has submitted a Preliminary Geotechnical Report, Technical
Information Report, Traffic Impact Analysis, and Stream Assessment and Final Mitigation Plan with the application.

Vehicular access to Southport West would be provided by Park Ave N, Lake Washington Blvd N, and the addition of an
internal center road and frontage road.
The site is generally level and consists of gravel yard and asphalt, a Puget Sound Energy switchgear, and an
office/warehouse building. The site contains high seismic hazard areas and the northeast corner of the site contains
Johns Creek and regulated slopes. The soil consists of a loose to medium dense sand, underlain by soft to medium dense
silt, then medium dense to dense sand, very soft silt and clay, and finally dense to very dense silty sand. Groundwater
was observed in the historical exploration at Southport at depths ranging from 3 to 10 feet below existing grade.
Preliminary estimates of cut and fill include approximately 25,000 cubic yards of excavation and 39,200 cubic yards of fill
from an approved source. The depth of excavation is anticipated to not exceed approximately two feet (2’) below ground
level, except for building cores where excavation would be deeper. Stormwater runoff from pollution generating surfaces
would be captured by catch basins and treated in cartridge filter facilities prior to connection into three (3) existing
drainage systems. No significant trees are proposed to be removed. Southport is proposing to plant 115 new trees along
with a variety of shrubs and perennials. The applicant has submitted a Preliminary Geotechnical Report, Technical
Information Report, Traffic Impact Analysis, and Stream Assessment and Final Mitigation Plan with the application.

PROJECT DESCRIPTION: The applicant, Southport West LLC, is requesting Master Plan Review, Hearing Examiner
Site Plan Review and Environmental (SEPA) Review for the construction of Southport West. Southport West is the
completion of the southerly portion of the Southport Development located at the south end of Lake Washington Blvd N.
The proposed expansion of Southport would be located on the 10.09-acre former Puget Sound Energy (PSE) Substation
and PSE utility parcels (APNs 082305-9191 and -9178). The two (2) parcels are located in the Urban Center-2 (UC-2) zone
and the Urban Design District ‘C’. The site is proposed to be developed as five (5) high-rise buildings with approximately
1,200,000 square feet of office and 50,000 of retail development in multiple phases. The proposed first three phases
would be developed as follows: Phase I – Towers 1 and 2 with the garage podium (July 2023 – July 2027), Phase II –
Towers 3 and 4 with garage podium (July 2027 – July 2031), and Phase III – Tower 5 (post July 2031). Phases 1-3 would
start on the south side of the site (closer to Boeing) and would develop to the north side of the lot (closer to Gene Coulon
Memorial Beach Park). A fourth and final phase is being considered for a sixth tower with 130,000 square feet for office
and retail at the south corner of the development near the intersection of Park Ave N and 757th Ave NE. The phased
development could reach as high as 1.6 million gross square feet. The proposed nine-level development would be built
at the same height and scale as the existing Southport offices with an overall height of approximately 154 feet above
average grade. Parking for 2,207 vehicles would be provided in a shared 4- and 5-level parking garage and 57 spaces are
proposed as on-street parking. In addition, the applicant is proposing to work closely with PSE for the engineering and

capacity needs of the development in order to relocate the powerlines and utility switchgear adjacent to Johns Creek.
Vehicular access to Southport West would be provided by Park Ave N, Lake Washington Blvd N, and the addition of an
internal center road and frontage road.
The site is generally level and consists of gravel yard and asphalt, a Puget Sound Energy switchgear, and an
office/warehouse building. The site contains high seismic hazard areas and the northeast corner of the site contains
Johns Creek and regulated slopes. The soil consists of a loose to medium dense sand, underlain by soft to medium dense
silt, then medium dense to dense sand, very soft silt and clay, and finally dense to very dense silty sand. Groundwater
was observed in the historical exploration at Southport at depths ranging from 3 to 10 feet below existing grade.
Preliminary estimates of cut and fill include approximately 25,000 cubic yards of excavation and 39,200 cubic yards of fill
from an approved source. The depth of excavation is anticipated to not exceed approximately two feet (2’) below ground
level, except for building cores where excavation would be deeper. Stormwater runoff from pollution generating surfaces
would be captured by catch basins and treated in cartridge filter facilities prior to connection into three (3) existing
drainage systems. No significant trees are proposed to be removed. Southport is proposing to plant 115 new trees along
with a variety of shrubs and perennials. The applicant has submitted a Preliminary Geotechnical Report, Technical
Information Report, Traffic Impact Analysis, and Stream Assessment and Final Mitigation Plan with the application.

PROJECT DESCRIPTION: The applicant, Southport West LLC, is requesting Master Plan Review, Hearing Examiner
Site Plan Review and Environmental (SEPA) Review for the construction of Southport West. Southport West is the
completion of the southerly portion of the Southport Development located at the south end of Lake Washington Blvd N.
The proposed expansion of Southport would be located on the 10.09-acre former Puget Sound Energy (PSE) Substation
and PSE utility parcels (APNs 082305-9191 and -9178). The two (2) parcels are located in the Urban Center-2 (UC-2) zone
and the Urban Design District ‘C’. The site is proposed to be developed as five (5) high-rise buildings with approximately
1,200,000 square feet of office and 50,000 of retail development in multiple phases. The proposed first three phases
would be developed as follows: Phase I – Towers 1 and 2 with the garage podium (July 2023 – July 2027), Phase II –
Towers 3 and 4 with garage podium (July 2027 – July 2031), and Phase III – Tower 5 (post July 2031). Phases 1-3 would
start on the south side of the site (closer to Boeing) and would develop to the north side of the lot (closer to Gene Coulon
Memorial Beach Park). A fourth and final phase is being considered for a sixth tower with 130,000 square feet for office
and retail at the south corner of the development near the intersection of Park Ave N and 757th Ave NE. The phased
development could reach as high as 1.6 million gross square feet. The proposed nine-level development would be built
at the same height and scale as the existing Southport offices with an overall height of approximately 154 feet above
average grade. Parking for 2,207 vehicles would be provided in a shared 4- and 5-level parking garage and 57 spaces are
proposed as on-street parking. In addition, the applicant is proposing to work closely with PSE for the engineering and

capacity needs of the development in order to relocate the powerlines and utility switchgear adjacent to Johns Creek.
Vehicular access to Southport West would be provided by Park Ave N, Lake Washington Blvd N, and the addition of an
internal center road and frontage road.
The site is generally level and consists of gravel yard and asphalt, a Puget Sound Energy switchgear, and an
office/warehouse building. The site contains high seismic hazard areas and the northeast corner of the site contains
Johns Creek and regulated slopes. The soil consists of a loose to medium dense sand, underlain by soft to medium dense
silt, then medium dense to dense sand, very soft silt and clay, and finally dense to very dense silty sand. Groundwater
was observed in the historical exploration at Southport at depths ranging from 3 to 10 feet below existing grade.
Preliminary estimates of cut and fill include approximately 25,000 cubic yards of excavation and 39,200 cubic yards of fill
from an approved source. The depth of excavation is anticipated to not exceed approximately two feet (2’) below ground
level, except for building cores where excavation would be deeper. Stormwater runoff from pollution generating surfaces
would be captured by catch basins and treated in cartridge filter facilities prior to connection into three (3) existing
drainage systems. No significant trees are proposed to be removed. Southport is proposing to plant 115 new trees along
with a variety of shrubs and perennials. The applicant has submitted a Preliminary Geotechnical Report, Technical
Information Report, Traffic Impact Analysis, and Stream Assessment and Final Mitigation Plan with the application.

PROJECT DESCRIPTION: The applicant, Southport West LLC, is requesting Master Plan Review, Hearing Examiner
Site Plan Review and Environmental (SEPA) Review for the construction of Southport West. Southport West is the
completion of the southerly portion of the Southport Development located at the south end of Lake Washington Blvd N.
The proposed expansion of Southport would be located on the 10.09-acre former Puget Sound Energy (PSE) Substation
and PSE utility parcels (APNs 082305-9191 and -9178). The two (2) parcels are located in the Urban Center-2 (UC-2) zone
and the Urban Design District ‘C’. The site is proposed to be developed as five (5) high-rise buildings with approximately
1,200,000 square feet of office and 50,000 of retail development in multiple phases. The proposed first three phases
would be developed as follows: Phase I – Towers 1 and 2 with the garage podium (July 2023 – July 2027), Phase II –
Towers 3 and 4 with garage podium (July 2027 – July 2031), and Phase III – Tower 5 (post July 2031). Phases 1-3 would
start on the south side of the site (closer to Boeing) and would develop to the north side of the lot (closer to Gene Coulon
Memorial Beach Park). A fourth and final phase is being considered for a sixth tower with 130,000 square feet for office
and retail at the south corner of the development near the intersection of Park Ave N and 757th Ave NE. The phased
development could reach as high as 1.6 million gross square feet. The proposed nine-level development would be built
at the same height and scale as the existing Southport offices with an overall height of approximately 154 feet above
average grade. Parking for 2,207 vehicles would be provided in a shared 4- and 5-level parking garage and 57 spaces are
proposed as on-street parking. In addition, the applicant is proposing to work closely with PSE for the engineering and

Vehicular access to Southport West would be provided by Park Ave N, Lake Washington Blvd N, and the addition of an
internal center road and frontage road.
The site is generally level and consists of gravel yard and asphalt, a Puget Sound Energy switchgear, and an
office/warehouse building. The site contains high seismic hazard areas and the northeast corner of the site contains
Johns Creek and regulated slopes. The soil consists of a loose to medium dense sand, underlain by soft to medium dense
silt, then medium dense to dense sand, very soft silt and clay, and finally dense to very dense silty sand. Groundwater
was observed in the historical exploration at Southport at depths ranging from 3 to 10 feet below existing grade.
Preliminary estimates of cut and fill include approximately 25,000 cubic yards of excavation and 39,200 cubic yards of fill
from an approved source. The depth of excavation is anticipated to not exceed approximately two feet (2’) below ground
level, except for building cores where excavation would be deeper. Stormwater runoff from pollution generating surfaces
would be captured by catch basins and treated in cartridge filter facilities prior to connection into three (3) existing

PROJECT DESCRIPTION: The applicant, Southport West LLC, is requesting Master Plan Review, Hearing Examiner
Site Plan Review and Environmental (SEPA) Review for the construction of Southport West. Southport West is the
completion of the southerly portion of the Southport Development located at the south end of Lake Washington Blvd N.
The proposed expansion of Southport would be located on the 10.09-acre former Puget Sound Energy (PSE) Substation
and PSE utility parcels (APNs 082305-9191 and -9178). The two (2) parcels are located in the Urban Center-2 (UC-2) zone
and the Urban Design District ‘C’. The site is proposed to be developed as five (5) high-rise buildings with approximately
1,200,000 square feet of office and 50,000 of retail development in multiple phases. The proposed first three phases
would be developed as follows: Phase I – Towers 1 and 2 with the garage podium (July 2023 – July 2027), Phase II –
Towers 3 and 4 with garage podium (July 2027 – July 2031), and Phase III – Tower 5 (post July 2031). Phases 1-3 would
start on the south side of the site (closer to Boeing) and would develop to the north side of the lot (closer to Gene Coulon
Memorial Beach Park). A fourth and final phase is being considered for a sixth tower with 130,000 square feet for office
and retail at the south corner of the development near the intersection of Park Ave N and 757th Ave NE. The phased
development could reach as high as 1.6 million gross square feet. The proposed nine-level development would be built
at the same height and scale as the existing Southport offices with an overall height of approximately 154 feet above
average grade. Parking for 2,207 vehicles would be provided in a shared 4- and 5-level parking garage and 57 spaces are
proposed as on-street parking. In addition, the applicant is proposing to work closely with PSE for the engineering and

capacity needs of the development in order to relocate the powerlines and utility switchgear adjacent to Johns Creek.
Vehicular access to Southport West would be provided by Park Ave N, Lake Washington Blvd N, and the addition of an
internal center road and frontage road.
The site is generally level and consists of gravel yard and asphalt, a Puget Sound Energy switchgear, and an
office/warehouse building. The site contains high seismic hazard areas and the northeast corner of the site contains
Johns Creek and regulated slopes. The soil consists of a loose to medium dense sand, underlain by soft to medium dense
silt, then medium dense to dense sand, very soft silt and clay, and finally dense to very dense silty sand. Groundwater
was observed in the historical exploration at Southport at depths ranging from 3 to 10 feet below existing grade.
Preliminary estimates of cut and fill include approximately 25,000 cubic yards of excavation and 39,200 cubic yards of fill
from an approved source. The depth of excavation is anticipated to not exceed approximately two feet (2’) below ground
level, except for building cores where excavation would be deeper. Stormwater runoff from pollution generating surfaces
would be captured by catch basins and treated in cartridge filter facilities prior to connection into three (3) existing
drainage systems. No significant trees are proposed to be removed. Southport is proposing to plant 115 new trees along
with a variety of shrubs and perennials. The applicant has submitted a Preliminary Geotechnical Report, Technical
Information Report, Traffic Impact Analysis, and Stream Assessment and Final Mitigation Plan with the application.

capacity needs of the development in order to relocate the powerlines and utility switchgear adjacent to Johns Creek.
Vehicular access to Southport West would be provided by Park Ave N, Lake Washington Blvd N, and the addition of an
internal center road and frontage road.
The site is generally level and consists of gravel yard and asphalt, a Puget Sound Energy switchgear, and an
office/warehouse building. The site contains high seismic hazard areas and the northeast corner of the site contains
Johns Creek and regulated slopes. The soil consists of a loose to medium dense sand, underlain by soft to medium dense
silt, then medium dense to dense sand, very soft silt and clay, and finally dense to very dense silty sand. Groundwater
was observed in the historical exploration at Southport at depths ranging from 3 to 10 feet below existing grade.
Preliminary estimates of cut and fill include approximately 25,000 cubic yards of excavation and 39,200 cubic yards of fill
from an approved source. The depth of excavation is anticipated to not exceed approximately two feet (2’) below ground
level, except for building cores where excavation would be deeper. Stormwater runoff from pollution generating surfaces
would be captured by catch basins and treated in cartridge filter facilities prior to connection into three (3) existing
drainage systems. No significant trees are proposed to be removed. Southport is proposing to plant 115 new trees along
with a variety of shrubs and perennials. The applicant has submitted a Preliminary Geotechnical Report, Technical
Information Report, Traffic Impact Analysis, and Stream Assessment and Final Mitigation Plan with the application.

PROJECT DESCRIPTION: The applicant, Southport West LLC, is requesting Master Plan Review, Hearing Examiner
Site Plan Review and Environmental (SEPA) Review for the construction of Southport West. Southport West is the
completion of the southerly portion of the Southport Development located at the south end of Lake Washington Blvd N.
The proposed expansion of Southport would be located on the 10.09-acre former Puget Sound Energy (PSE) Substation
and PSE utility parcels (APNs 082305-9191 and -9178). The two (2) parcels are located in the Urban Center-2 (UC-2) zone
and the Urban Design District ‘C’. The site is proposed to be developed as five (5) high-rise buildings with approximately
1,200,000 square feet of office and 50,000 of retail development in multiple phases. The proposed first three phases
would be developed as follows: Phase I – Towers 1 and 2 with the garage podium (July 2023 – July 2027), Phase II –
Towers 3 and 4 with garage podium (July 2027 – July 2031), and Phase III – Tower 5 (post July 2031). Phases 1-3 would
start on the south side of the site (closer to Boeing) and would develop to the north side of the lot (closer to Gene Coulon
Memorial Beach Park). A fourth and final phase is being considered for a sixth tower with 130,000 square feet for office
and retail at the south corner of the development near the intersection of Park Ave N and 757th Ave NE. The phased
development could reach as high as 1.6 million gross square feet. The proposed nine-level development would be built
at the same height and scale as the existing Southport offices with an overall height of approximately 154 feet above
average grade. Parking for 2,207 vehicles would be provided in a shared 4- and 5-level parking garage and 57 spaces are
proposed as on-street parking. In addition, the applicant is proposing to work closely with PSE for the engineering and

PROJECT DESCRIPTION: The applicant, Southport West LLC, is requesting Master Plan Review, Hearing Examiner
Site Plan Review and Environmental (SEPA) Review for the construction of Southport West. Southport West is the
completion of the southerly portion of the Southport Development located at the south end of Lake Washington Blvd N.
The proposed expansion of Southport would be located on the 10.09-acre former Puget Sound Energy (PSE) Substation
and PSE utility parcels (APNs 082305-9191 and -9178). The two (2) parcels are located in the Urban Center-2 (UC-2) zone
and the Urban Design District ‘C’. The site is proposed to be developed as five (5) high-rise buildings with approximately
1,200,000 square feet of office and 50,000 of retail development in multiple phases. The proposed first three phases
would be developed as follows: Phase I – Towers 1 and 2 with the garage podium (July 2023 – July 2027), Phase II –
Towers 3 and 4 with garage podium (July 2027 – July 2031), and Phase III – Tower 5 (post July 2031). Phases 1-3 would
start on the south side of the site (closer to Boeing) and would develop to the north side of the lot (closer to Gene Coulon
Memorial Beach Park). A fourth and final phase is being considered for a sixth tower with 130,000 square feet for office
and retail at the south corner of the development near the intersection of Park Ave N and 757th Ave NE. The phased
development could reach as high as 1.6 million gross square feet. The proposed nine-level development would be built
at the same height and scale as the existing Southport offices with an overall height of approximately 154 feet above
average grade. Parking for 2,207 vehicles would be provided in a shared 4- and 5-level parking garage and 57 spaces are
proposed as on-street parking. In addition, the applicant is proposing to work closely with PSE for the engineering and

capacity needs of the development in order to relocate the powerlines and utility switchgear adjacent to Johns Creek.
Vehicular access to Southport West would be provided by Park Ave N, Lake Washington Blvd N, and the addition of an
internal center road and frontage road.
The site is generally level and consists of gravel yard and asphalt, a Puget Sound Energy switchgear, and an
office/warehouse building. The site contains high seismic hazard areas and the northeast corner of the site contains
Johns Creek and regulated slopes. The soil consists of a loose to medium dense sand, underlain by soft to medium dense
silt, then medium dense to dense sand, very soft silt and clay, and finally dense to very dense silty sand. Groundwater
was observed in the historical exploration at Southport at depths ranging from 3 to 10 feet below existing grade.
Preliminary estimates of cut and fill include approximately 25,000 cubic yards of excavation and 39,200 cubic yards of fill
from an approved source. The depth of excavation is anticipated to not exceed approximately two feet (2’) below ground
level, except for building cores where excavation would be deeper. Stormwater runoff from pollution generating surfaces
would be captured by catch basins and treated in cartridge filter facilities prior to connection into three (3) existing
drainage systems. No significant trees are proposed to be removed. Southport is proposing to plant 115 new trees along
with a variety of shrubs and perennials. The applicant has submitted a Preliminary Geotechnical Report, Technical
Information Report, Traffic Impact Analysis, and Stream Assessment and Final Mitigation Plan with the application.

Towers 3 and 4 with garage podium (July 2027 – July 2031), and Phase III – Tower 5 (post July 2031). Phases 1-3 would
start on the south side of the site (closer to Boeing) and would develop to the north side of the lot (closer to Gene Coulon
Memorial Beach Park). A fourth and final phase is being considered for a sixth tower with 130,000 square feet for office
and retail at the south corner of the development near the intersection of Park Ave N and 757th Ave NE. The phased
development could reach as high as 1.6 million gross square feet. The proposed nine-level development would be built
at the same height and scale as the existing Southport offices with an overall height of approximately 154 feet above
average grade. Parking for 2,207 vehicles would be provided in a shared 4- and 5-level parking garage and 57 spaces are
proposed as on-street parking. In addition, the applicant is proposing to work closely with PSE for the engineering and

Vehicular access to Southport West would be provided by Park Ave N, Lake Washington Blvd N, and the addition of an
internal center road and frontage road.
The site is generally level and consists of gravel yard and asphalt, a Puget Sound Energy switchgear, and an
office/warehouse building. The site contains high seismic hazard areas and the northeast corner of the site contains
Johns Creek and regulated slopes. The soil consists of a loose to medium dense sand, underlain by soft to medium dense
silt, then medium dense to dense sand, very soft silt and clay, and finally dense to very dense silty sand. Groundwater
was observed in the historical exploration at Southport at depths ranging from 3 to 10 feet below existing grade.
Preliminary estimates of cut and fill include approximately 25,000 cubic yards of excavation and 39,200 cubic yards of fill
from an approved source. The depth of excavation is anticipated to not exceed approximately two feet (2’) below ground
level, except for building cores where excavation would be deeper. Stormwater runoff from pollution generating surfaces
would be captured by catch basins and treated in cartridge filter facilities prior to connection into three (3) existing
drainage systems. No significant trees are proposed to be removed. Southport is proposing to plant 115 new trees along
with a variety of shrubs and perennials. The applicant has submitted a Preliminary Geotechnical Report, Technical
Information Report, Traffic Impact Analysis, and Stream Assessment and Final Mitigation Plan with the application.

PROJECT DESCRIPTION: The applicant, Southport West LLC, is requesting Master Plan Review, Hearing Examiner
Site Plan Review and Environmental (SEPA) Review for the construction of Southport West. Southport West is the
completion of the southerly portion of the Southport Development located at the south end of Lake Washington Blvd N.
The proposed expansion of Southport would be located on the 10.09-acre former Puget Sound Energy (PSE) Substation
and PSE utility parcels (APNs 082305-9191 and -9178). The two (2) parcels are located in the Urban Center-2 (UC-2) zone
and the Urban Design District ‘C’. The site is proposed to be developed as five (5) high-rise buildings with approximately
1,200,000 square feet of office and 50,000 of retail development in multiple phases. The proposed first three phases
would be developed as follows: Phase I – Towers 1 and 2 with the garage podium (July 2023 – July 2027), Phase II –
Towers 3 and 4 with garage podium (July 2027 – July 2031), and Phase III – Tower 5 (post July 2031). Phases 1-3 would
start on the south side of the site (closer to Boeing) and would develop to the north side of the lot (closer to Gene Coulon
Memorial Beach Park). A fourth and final phase is being considered for a sixth tower with 130,000 square feet for office
and retail at the south corner of the development near the intersection of Park Ave N and 757th Ave NE. The phased
development could reach as high as 1.6 million gross square feet. The proposed nine-level development would be built
at the same height and scale as the existing Southport offices with an overall height of approximately 154 feet above
average grade. Parking for 2,207 vehicles would be provided in a shared 4- and 5-level parking garage and 57 spaces are
proposed as on-street parking. In addition, the applicant is proposing to work closely with PSE for the engineering and

capacity needs of the development in order to relocate the powerlines and utility switchgear adjacent to Johns Creek.
Vehicular access to Southport West would be provided by Park Ave N, Lake Washington Blvd N, and the addition of an
internal center road and frontage road.
The site is generally level and consists of gravel yard and asphalt, a Puget Sound Energy switchgear, and an
office/warehouse building. The site contains high seismic hazard areas and the northeast corner of the site contains
Johns Creek and regulated slopes. The soil consists of a loose to medium dense sand, underlain by soft to medium dense
silt, then medium dense to dense sand, very soft silt and clay, and finally dense to very dense silty sand. Groundwater
was observed in the historical exploration at Southport at depths ranging from 3 to 10 feet below existing grade.
Preliminary estimates of cut and fill include approximately 25,000 cubic yards of excavation and 39,200 cubic yards of fill
from an approved source. The depth of excavation is anticipated to not exceed approximately two feet (2’) below ground
level, except for building cores where excavation would be deeper. Stormwater runoff from pollution generating surfaces
would be captured by catch basins and treated in cartridge filter facilities prior to connection into three (3) existing
drainage systems. No significant trees are proposed to be removed. Southport is proposing to plant 115 new trees along
with a variety of shrubs and perennials. The applicant has submitted a Preliminary Geotechnical Report, Technical
Information Report, Traffic Impact Analysis, and Stream Assessment and Final Mitigation Plan with the application.

PROJECT DESCRIPTION: The applicant, Southport West LLC, is requesting Master Plan Review, Hearing Examiner
Site Plan Review and Environmental (SEPA) Review for the construction of Southport West. Southport West is the
completion of the southerly portion of the Southport Development located at the south end of Lake Washington Blvd N.
The proposed expansion of Southport would be located on the 10.09-acre former Puget Sound Energy (PSE) Substation
and PSE utility parcels (APNs 082305-9191 and -9178). The two (2) parcels are located in the Urban Center-2 (UC-2) zone
and the Urban Design District ‘C’. The site is proposed to be developed as five (5) high-rise buildings with approximately
1,200,000 square feet of office and 50,000 of retail development in multiple phases. The proposed first three phases
would be developed as follows: Phase I – Towers 1 and 2 with the garage podium (July 2023 – July 2027), Phase II –
Towers 3 and 4 with garage podium (July 2027 – July 2031), and Phase III – Tower 5 (post July 2031). Phases 1-3 would
start on the south side of the site (closer to Boeing) and would develop to the north side of the lot (closer to Gene Coulon
Memorial Beach Park). A fourth and final phase is being considered for a sixth tower with 130,000 square feet for office
and retail at the south corner of the development near the intersection of Park Ave N and 757th Ave NE. The phased
development could reach as high as 1.6 million gross square feet. The proposed nine-level development would be built
at the same height and scale as the existing Southport offices with an overall height of approximately 154 feet above
average grade. Parking for 2,207 vehicles would be provided in a shared 4- and 5-level parking garage and 57 spaces are
proposed as on-street parking. In addition, the applicant is proposing to work closely with PSE for the engineering and

capacity needs of the development in order to relocate the powerlines and utility switchgear adjacent to Johns Creek.
Vehicular access to Southport West would be provided by Park Ave N, Lake Washington Blvd N, and the addition of an
internal center road and frontage road.
The site is generally level and consists of gravel yard and asphalt, a Puget Sound Energy switchgear, and an
office/warehouse building. The site contains high seismic hazard areas and the northeast corner of the site contains
Johns Creek and regulated slopes. The soil consists of a loose to medium dense sand, underlain by soft to medium dense
silt, then medium dense to dense sand, very soft silt and clay, and finally dense to very dense silty sand. Groundwater
was observed in the historical exploration at Southport at depths ranging from 3 to 10 feet below existing grade.
Preliminary estimates of cut and fill include approximately 25,000 cubic yards of excavation and 39,200 cubic yards of fill
from an approved source. The depth of excavation is anticipated to not exceed approximately two feet (2’) below ground
level, except for building cores where excavation would be deeper. Stormwater runoff from pollution generating surfaces
would be captured by catch basins and treated in cartridge filter facilities prior to connection into three (3) existing
drainage systems. No significant trees are proposed to be removed. Southport is proposing to plant 115 new trees along
with a variety of shrubs and perennials. The applicant has submitted a Preliminary Geotechnical Report, Technical
Information Report, Traffic Impact Analysis, and Stream Assessment and Final Mitigation Plan with the application.

office/warehouse building. The site contains high seismic hazard areas and the northeast corner of the site contains
Johns Creek and regulated slopes. The soil consists of a loose to medium dense sand, underlain by soft to medium dense
silt, then medium dense to dense sand, very soft silt and clay, and finally dense to very dense silty sand. Groundwater
was observed in the historical exploration at Southport at depths ranging from 3 to 10 feet below existing grade.
Preliminary estimates of cut and fill include approximately 25,000 cubic yards of excavation and 39,200 cubic yards of fill
from an approved source. The depth of excavation is anticipated to not exceed approximately two feet (2’) below ground
level, except for building cores where excavation would be deeper. Stormwater runoff from pollution generating surfaces
would be captured by catch basins and treated in cartridge filter facilities prior to connection into three (3) existing
drainage systems. No significant trees are proposed to be removed. Southport is proposing to plant 115 new trees along
with a variety of shrubs and perennials. The applicant has submitted a Preliminary Geotechnical Report, Technical
Information Report, Traffic Impact Analysis, and Stream Assessment and Final Mitigation Plan with the application.

Site Plan Review and Environmental (SEPA) Review for the construction of Southport West. Southport West is the
completion of the southerly portion of the Southport Development located at the south end of Lake Washington Blvd N.
The proposed expansion of Southport would be located on the 10.09-acre former Puget Sound Energy (PSE) Substation
and PSE utility parcels (APNs 082305-9191 and -9178). The two (2) parcels are located in the Urban Center-2 (UC-2) zone
and the Urban Design District ‘C’. The site is proposed to be developed as five (5) high-rise buildings with approximately
1,200,000 square feet of office and 50,000 of retail development in multiple phases. The proposed first three phases
would be developed as follows: Phase I – Towers 1 and 2 with the garage podium (July 2023 – July 2027), Phase II –
Towers 3 and 4 with garage podium (July 2027 – July 2031), and Phase III – Tower 5 (post July 2031). Phases 1-3 would
start on the south side of the site (closer to Boeing) and would develop to the north side of the lot (closer to Gene Coulon
Memorial Beach Park). A fourth and final phase is being considered for a sixth tower with 130,000 square feet for office
and retail at the south corner of the development near the intersection of Park Ave N and 757th Ave NE. The phased
development could reach as high as 1.6 million gross square feet. The proposed nine-level development would be built
at the same height and scale as the existing Southport offices with an overall height of approximately 154 feet above
average grade. Parking for 2,207 vehicles would be provided in a shared 4- and 5-level parking garage and 57 spaces are
proposed as on-street parking. In addition, the applicant is proposing to work closely with PSE for the engineering and

PROJECT DESCRIPTION: The applicant, Southport West LLC, is requesting Master Plan Review, Hearing Examiner
Site Plan Review and Environmental (SEPA) Review for the construction of Southport West. Southport West is the
completion of the southerly portion of the Southport Development located at the south end of Lake Washington Blvd N.
The proposed expansion of Southport would be located on the 10.09-acre former Puget Sound Energy (PSE) Substation
and PSE utility parcels (APNs 082305-9191 and -9178). The two (2) parcels are located in the Urban Center-2 (UC-2) zone
and the Urban Design District ‘C’. The site is proposed to be developed as five (5) high-rise buildings with approximately
1,200,000 square feet of office and 50,000 of retail development in multiple phases. The proposed first three phases
would be developed as follows: Phase I – Towers 1 and 2 with the garage podium (July 2023 – July 2027), Phase II –
Towers 3 and 4 with garage podium (July 2027 – July 2031), and Phase III – Tower 5 (post July 2031). Phases 1-3 would
start on the south side of the site (closer to Boeing) and would develop to the north side of the lot (closer to Gene Coulon
Memorial Beach Park). A fourth and final phase is being considered for a sixth tower with 130,000 square feet for office
and retail at the south corner of the development near the intersection of Park Ave N and 757th Ave NE. The phased
development could reach as high as 1.6 million gross square feet. The proposed nine-level development would be built
at the same height and scale as the existing Southport offices with an overall height of approximately 154 feet above
average grade. Parking for 2,207 vehicles would be provided in a shared 4- and 5-level parking garage and 57 spaces are
proposed as on-street parking. In addition, the applicant is proposing to work closely with PSE for the engineering and

capacity needs of the development in order to relocate the powerlines and utility switchgear adjacent to Johns Creek.
Vehicular access to Southport West would be provided by Park Ave N, Lake Washington Blvd N, and the addition of an
internal center road and frontage road.
The site is generally level and consists of gravel yard and asphalt, a Puget Sound Energy switchgear, and an
office/warehouse building. The site contains high seismic hazard areas and the northeast corner of the site contains
Johns Creek and regulated slopes. The soil consists of a loose to medium dense sand, underlain by soft to medium dense
silt, then medium dense to dense sand, very soft silt and clay, and finally dense to very dense silty sand. Groundwater
was observed in the historical exploration at Southport at depths ranging from 3 to 10 feet below existing grade.
Preliminary estimates of cut and fill include approximately 25,000 cubic yards of excavation and 39,200 cubic yards of fill
from an approved source. The depth of excavation is anticipated to not exceed approximately two feet (2’) below ground
level, except for building cores where excavation would be deeper. Stormwater runoff from pollution generating surfaces
would be captured by catch basins and treated in cartridge filter facilities prior to connection into three (3) existing
drainage systems. No significant trees are proposed to be removed. Southport is proposing to plant 115 new trees along
with a variety of shrubs and perennials. The applicant has submitted a Preliminary Geotechnical Report, Technical
Information Report, Traffic Impact Analysis, and Stream Assessment and Final Mitigation Plan with the application.

capacity needs of the development in order to relocate the powerlines and utility switchgear adjacent to Johns Creek.
Vehicular access to Southport West would be provided by Park Ave N, Lake Washington Blvd N, and the addition of an
internal center road and frontage road.
The site is generally level and consists of gravel yard and asphalt, a Puget Sound Energy switchgear, and an
office/warehouse building. The site contains high seismic hazard areas and the northeast corner of the site contains
Johns Creek and regulated slopes. The soil consists of a loose to medium dense sand, underlain by soft to medium dense
silt, then medium dense to dense sand, very soft silt and clay, and finally dense to very dense silty sand. Groundwater
was observed in the historical exploration at Southport at depths ranging from 3 to 10 feet below existing grade.
Preliminary estimates of cut and fill include approximately 25,000 cubic yards of excavation and 39,200 cubic yards of fill
from an approved source. The depth of excavation is anticipated to not exceed approximately two feet (2’) below ground
level, except for building cores where excavation would be deeper. Stormwater runoff from pollution generating surfaces
would be captured by catch basins and treated in cartridge filter facilities prior to connection into three (3) existing
drainage systems. No significant trees are proposed to be removed. Southport is proposing to plant 115 new trees along
with a variety of shrubs and perennials. The applicant has submitted a Preliminary Geotechnical Report, Technical
Information Report, Traffic Impact Analysis, and Stream Assessment and Final Mitigation Plan with the application.

The proposed expansion of Southport would be located on the 10.09-acre former Puget Sound Energy (PSE) Substation
and PSE utility parcels (APNs 082305-9191 and -9178). The two (2) parcels are located in the Urban Center-2 (UC-2) zone
and the Urban Design District ‘C’. The site is proposed to be developed as five (5) high-rise buildings with approximately
1,200,000 square feet of office and 50,000 of retail development in multiple phases. The proposed first three phases
would be developed as follows: Phase I – Towers 1 and 2 with the garage podium (July 2023 – July 2027), Phase II –
Towers 3 and 4 with garage podium (July 2027 – July 2031), and Phase III – Tower 5 (post July 2031). Phases 1-3 would
start on the south side of the site (closer to Boeing) and would develop to the north side of the lot (closer to Gene Coulon
Memorial Beach Park). A fourth and final phase is being considered for a sixth tower with 130,000 square feet for office
and retail at the south corner of the development near the intersection of Park Ave N and 757th Ave NE. The phased
development could reach as high as 1.6 million gross square feet. The proposed nine-level development would be built
at the same height and scale as the existing Southport offices with an overall height of approximately 154 feet above
average grade. Parking for 2,207 vehicles would be provided in a shared 4- and 5-level parking garage and 57 spaces are

PROJECT DESCRIPTION: The applicant, Southport West LLC, is requesting Master Plan Review, Hearing Examiner
Site Plan Review and Environmental (SEPA) Review for the construction of Southport West. Southport West is the
completion of the southerly portion of the Southport Development located at the south end of Lake Washington Blvd N.
The proposed expansion of Southport would be located on the 10.09-acre former Puget Sound Energy (PSE) Substation
and PSE utility parcels (APNs 082305-9191 and -9178). The two (2) parcels are located in the Urban Center-2 (UC-2) zone
and the Urban Design District ‘C’. The site is proposed to be developed as five (5) high-rise buildings with approximately
1,200,000 square feet of office and 50,000 of retail development in multiple phases. The proposed first three phases
would be developed as follows: Phase I – Towers 1 and 2 with the garage podium (July 2023 – July 2027), Phase II –
Towers 3 and 4 with garage podium (July 2027 – July 2031), and Phase III – Tower 5 (post July 2031). Phases 1-3 would
start on the south side of the site (closer to Boeing) and would develop to the north side of the lot (closer to Gene Coulon
Memorial Beach Park). A fourth and final phase is being considered for a sixth tower with 130,000 square feet for office
and retail at the south corner of the development near the intersection of Park Ave N and 757th Ave NE. The phased
development could reach as high as 1.6 million gross square feet. The proposed nine-level development would be built
at the same height and scale as the existing Southport offices with an overall height of approximately 154 feet above
average grade. Parking for 2,207 vehicles would be provided in a shared 4- and 5-level parking garage and 57 spaces are
proposed as on-street parking. In addition, the applicant is proposing to work closely with PSE for the engineering and

capacity needs of the development in order to relocate the powerlines and utility switchgear adjacent to Johns Creek.
Vehicular access to Southport West would be provided by Park Ave N, Lake Washington Blvd N, and the addition of an
internal center road and frontage road.
The site is generally level and consists of gravel yard and asphalt, a Puget Sound Energy switchgear, and an
office/warehouse building. The site contains high seismic hazard areas and the northeast corner of the site contains
Johns Creek and regulated slopes. The soil consists of a loose to medium dense sand, underlain by soft to medium dense
silt, then medium dense to dense sand, very soft silt and clay, and finally dense to very dense silty sand. Groundwater
was observed in the historical exploration at Southport at depths ranging from 3 to 10 feet below existing grade.
Preliminary estimates of cut and fill include approximately 25,000 cubic yards of excavation and 39,200 cubic yards of fill
from an approved source. The depth of excavation is anticipated to not exceed approximately two feet (2’) below ground
level, except for building cores where excavation would be deeper. Stormwater runoff from pollution generating surfaces
would be captured by catch basins and treated in cartridge filter facilities prior to connection into three (3) existing
drainage systems. No significant trees are proposed to be removed. Southport is proposing to plant 115 new trees along
with a variety of shrubs and perennials. The applicant has submitted a Preliminary Geotechnical Report, Technical
Information Report, Traffic Impact Analysis, and Stream Assessment and Final Mitigation Plan with the application.

and PSE utility parcels (APNs 082305-9191 and -9178). The two (2) parcels are located in the Urban Center-2 (UC-2) zone
and the Urban Design District ‘C’. The site is proposed to be developed as five (5) high-rise buildings with approximately
1,200,000 square feet of office and 50,000 of retail development in multiple phases. The proposed first three phases
would be developed as follows: Phase I – Towers 1 and 2 with the garage podium (July 2023 – July 2027), Phase II –
Towers 3 and 4 with garage podium (July 2027 – July 2031), and Phase III – Tower 5 (post July 2031). Phases 1-3 would
start on the south side of the site (closer to Boeing) and would develop to the north side of the lot (closer to Gene Coulon
Memorial Beach Park). A fourth and final phase is being considered for a sixth tower with 130,000 square feet for office
and retail at the south corner of the development near the intersection of Park Ave N and 757th Ave NE. The phased
development could reach as high as 1.6 million gross square feet. The proposed nine-level development would be built
at the same height and scale as the existing Southport offices with an overall height of approximately 154 feet above
average grade. Parking for 2,207 vehicles would be provided in a shared 4- and 5-level parking garage and 57 spaces are
proposed as on-street parking. In addition, the applicant is proposing to work closely with PSE for the engineering and

capacity needs of the development in order to relocate the powerlines and utility switchgear adjacent to Johns Creek.
Vehicular access to Southport West would be provided by Park Ave N, Lake Washington Blvd N, and the addition of an
internal center road and frontage road.
The site is generally level and consists of gravel yard and asphalt, a Puget Sound Energy switchgear, and an
office/warehouse building. The site contains high seismic hazard areas and the northeast corner of the site contains
Johns Creek and regulated slopes. The soil consists of a loose to medium dense sand, underlain by soft to medium dense
silt, then medium dense to dense sand, very soft silt and clay, and finally dense to very dense silty sand. Groundwater
was observed in the historical exploration at Southport at depths ranging from 3 to 10 feet below existing grade.
Preliminary estimates of cut and fill include approximately 25,000 cubic yards of excavation and 39,200 cubic yards of fill
from an approved source. The depth of excavation is anticipated to not exceed approximately two feet (2’) below ground
level, except for building cores where excavation would be deeper. Stormwater runoff from pollution generating surfaces
would be captured by catch basins and treated in cartridge filter facilities prior to connection into three (3) existing
drainage systems. No significant trees are proposed to be removed. Southport is proposing to plant 115 new trees along
with a variety of shrubs and perennials. The applicant has submitted a Preliminary Geotechnical Report, Technical
Information Report, Traffic Impact Analysis, and Stream Assessment and Final Mitigation Plan with the application.

PROJECT DESCRIPTION: The applicant, Southport West LLC, is requesting Master Plan Review, Hearing Examiner
Site Plan Review and Environmental (SEPA) Review for the construction of Southport West. Southport West is the
completion of the southerly portion of the Southport Development located at the south end of Lake Washington Blvd N.
The proposed expansion of Southport would be located on the 10.09-acre former Puget Sound Energy (PSE) Substation
and PSE utility parcels (APNs 082305-9191 and -9178). The two (2) parcels are located in the Urban Center-2 (UC-2) zone
and the Urban Design District ‘C’. The site is proposed to be developed as five (5) high-rise buildings with approximately
1,200,000 square feet of office and 50,000 of retail development in multiple phases. The proposed first three phases
would be developed as follows: Phase I – Towers 1 and 2 with the garage podium (July 2023 – July 2027), Phase II –
Towers 3 and 4 with garage podium (July 2027 – July 2031), and Phase III – Tower 5 (post July 2031). Phases 1-3 would
start on the south side of the site (closer to Boeing) and would develop to the north side of the lot (closer to Gene Coulon
Memorial Beach Park). A fourth and final phase is being considered for a sixth tower with 130,000 square feet for office
and retail at the south corner of the development near the intersection of Park Ave N and 757th Ave NE. The phased
development could reach as high as 1.6 million gross square feet. The proposed nine-level development would be built
at the same height and scale as the existing Southport offices with an overall height of approximately 154 feet above
average grade. Parking for 2,207 vehicles would be provided in a shared 4- and 5-level parking garage and 57 spaces are
proposed as on-street parking. In addition, the applicant is proposing to work closely with PSE for the engineering and

Vehicular access to Southport West would be provided by Park Ave N, Lake Washington Blvd N, and the addition of an
internal center road and frontage road.
The site is generally level and consists of gravel yard and asphalt, a Puget Sound Energy switchgear, and an
office/warehouse building. The site contains high seismic hazard areas and the northeast corner of the site contains
Johns Creek and regulated slopes. The soil consists of a loose to medium dense sand, underlain by soft to medium dense
silt, then medium dense to dense sand, very soft silt and clay, and finally dense to very dense silty sand. Groundwater
was observed in the historical exploration at Southport at depths ranging from 3 to 10 feet below existing grade.
Preliminary estimates of cut and fill include approximately 25,000 cubic yards of excavation and 39,200 cubic yards of fill
from an approved source. The depth of excavation is anticipated to not exceed approximately two feet (2’) below ground
level, except for building cores where excavation would be deeper. Stormwater runoff from pollution generating surfaces
would be captured by catch basins and treated in cartridge filter facilities prior to connection into three (3) existing
drainage systems. No significant trees are proposed to be removed. Southport is proposing to plant 115 new trees along
with a variety of shrubs and perennials. The applicant has submitted a Preliminary Geotechnical Report, Technical
Information Report, Traffic Impact Analysis, and Stream Assessment and Final Mitigation Plan with the application.

PROJECT DESCRIPTION: The applicant, Southport West LLC, is requesting Master Plan Review, Hearing Examiner
Site Plan Review and Environmental (SEPA) Review for the construction of Southport West. Southport West is the
completion of the southerly portion of the Southport Development located at the south end of Lake Washington Blvd N.
The proposed expansion of Southport would be located on the 10.09-acre former Puget Sound Energy (PSE) Substation
and PSE utility parcels (APNs 082305-9191 and -9178). The two (2) parcels are located in the Urban Center-2 (UC-2) zone
and the Urban Design District ‘C’. The site is proposed to be developed as five (5) high-rise buildings with approximately
1,200,000 square feet of office and 50,000 of retail development in multiple phases. The proposed first three phases
would be developed as follows: Phase I – Towers 1 and 2 with the garage podium (July 2023 – July 2027), Phase II –
Towers 3 and 4 with garage podium (July 2027 – July 2031), and Phase III – Tower 5 (post July 2031). Phases 1-3 would
start on the south side of the site (closer to Boeing) and would develop to the north side of the lot (closer to Gene Coulon
Memorial Beach Park). A fourth and final phase is being considered for a sixth tower with 130,000 square feet for office
and retail at the south corner of the development near the intersection of Park Ave N and 757th Ave NE. The phased
development could reach as high as 1.6 million gross square feet. The proposed nine-level development would be built
at the same height and scale as the existing Southport offices with an overall height of approximately 154 feet above
average grade. Parking for 2,207 vehicles would be provided in a shared 4- and 5-level parking garage and 57 spaces are
proposed as on-street parking. In addition, the applicant is proposing to work closely with PSE for the engineering and

capacity needs of the development in order to relocate the powerlines and utility switchgear adjacent to Johns Creek.
Vehicular access to Southport West would be provided by Park Ave N, Lake Washington Blvd N, and the addition of an
internal center road and frontage road.
The site is generally level and consists of gravel yard and asphalt, a Puget Sound Energy switchgear, and an
office/warehouse building. The site contains high seismic hazard areas and the northeast corner of the site contains
Johns Creek and regulated slopes. The soil consists of a loose to medium dense sand, underlain by soft to medium dense
silt, then medium dense to dense sand, very soft silt and clay, and finally dense to very dense silty sand. Groundwater
was observed in the historical exploration at Southport at depths ranging from 3 to 10 feet below existing grade.
Preliminary estimates of cut and fill include approximately 25,000 cubic yards of excavation and 39,200 cubic yards of fill
from an approved source. The depth of excavation is anticipated to not exceed approximately two feet (2’) below ground
level, except for building cores where excavation would be deeper. Stormwater runoff from pollution generating surfaces
would be captured by catch basins and treated in cartridge filter facilities prior to connection into three (3) existing
drainage systems. No significant trees are proposed to be removed. Southport is proposing to plant 115 new trees along
with a variety of shrubs and perennials. The applicant has submitted a Preliminary Geotechnical Report, Technical
Information Report, Traffic Impact Analysis, and Stream Assessment and Final Mitigation Plan with the application.

capacity needs of the development in order to relocate the powerlines and utility switchgear adjacent to Johns Creek.
Vehicular access to Southport West would be provided by Park Ave N, Lake Washington Blvd N, and the addition of an
internal center road and frontage road.
The site is generally level and consists of gravel yard and asphalt, a Puget Sound Energy switchgear, and an
office/warehouse building. The site contains high seismic hazard areas and the northeast corner of the site contains
Johns Creek and regulated slopes. The soil consists of a loose to medium dense sand, underlain by soft to medium dense
silt, then medium dense to dense sand, very soft silt and clay, and finally dense to very dense silty sand. Groundwater
was observed in the historical exploration at Southport at depths ranging from 3 to 10 feet below existing grade.
Preliminary estimates of cut and fill include approximately 25,000 cubic yards of excavation and 39,200 cubic yards of fill
from an approved source. The depth of excavation is anticipated to not exceed approximately two feet (2’) below ground
level, except for building cores where excavation would be deeper. Stormwater runoff from pollution generating surfaces
would be captured by catch basins and treated in cartridge filter facilities prior to connection into three (3) existing
drainage systems. No significant trees are proposed to be removed. Southport is proposing to plant 115 new trees along
with a variety of shrubs and perennials. The applicant has submitted a Preliminary Geotechnical Report, Technical
Information Report, Traffic Impact Analysis, and Stream Assessment and Final Mitigation Plan with the application.

Site Plan Review and Environmental (SEPA) Review for the construction of Southport West. Southport West is the
completion of the southerly portion of the Southport Development located at the south end of Lake Washington Blvd N.
The proposed expansion of Southport would be located on the 10.09-acre former Puget Sound Energy (PSE) Substation
and PSE utility parcels (APNs 082305-9191 and -9178). The two (2) parcels are located in the Urban Center-2 (UC-2) zone
and the Urban Design District ‘C’. The site is proposed to be developed as five (5) high-rise buildings with approximately
1,200,000 square feet of office and 50,000 of retail development in multiple phases. The proposed first three phases
would be developed as follows: Phase I – Towers 1 and 2 with the garage podium (July 2023 – July 2027), Phase II –
Towers 3 and 4 with garage podium (July 2027 – July 2031), and Phase III – Tower 5 (post July 2031). Phases 1-3 would
start on the south side of the site (closer to Boeing) and would develop to the north side of the lot (closer to Gene Coulon
Memorial Beach Park). A fourth and final phase is being considered for a sixth tower with 130,000 square feet for office
and retail at the south corner of the development near the intersection of Park Ave N and 757th Ave NE. The phased
development could reach as high as 1.6 million gross square feet. The proposed nine-level development would be built
at the same height and scale as the existing Southport offices with an overall height of approximately 154 feet above
average grade. Parking for 2,207 vehicles would be provided in a shared 4- and 5-level parking garage and 57 spaces are
proposed as on-street parking. In addition, the applicant is proposing to work closely with PSE for the engineering and

PROJECT DESCRIPTION: The applicant, Southport West LLC, is requesting Master Plan Review, Hearing Examiner
Site Plan Review and Environmental (SEPA) Review for the construction of Southport West. Southport West is the
completion of the southerly portion of the Southport Development located at the south end of Lake Washington Blvd N.
The proposed expansion of Southport would be located on the 10.09-acre former Puget Sound Energy (PSE) Substation
and PSE utility parcels (APNs 082305-9191 and -9178). The two (2) parcels are located in the Urban Center-2 (UC-2) zone
and the Urban Design District ‘C’. The site is proposed to be developed as five (5) high-rise buildings with approximately
1,200,000 square feet of office and 50,000 of retail development in multiple phases. The proposed first three phases
would be developed as follows: Phase I – Towers 1 and 2 with the garage podium (July 2023 – July 2027), Phase II –
Towers 3 and 4 with garage podium (July 2027 – July 2031), and Phase III – Tower 5 (post July 2031). Phases 1-3 would
start on the south side of the site (closer to Boeing) and would develop to the north side of the lot (closer to Gene Coulon
Memorial Beach Park). A fourth and final phase is being considered for a sixth tower with 130,000 square feet for office
and retail at the south corner of the development near the intersection of Park Ave N and 757th Ave NE. The phased
development could reach as high as 1.6 million gross square feet. The proposed nine-level development would be built
at the same height and scale as the existing Southport offices with an overall height of approximately 154 feet above
average grade. Parking for 2,207 vehicles would be provided in a shared 4- and 5-level parking garage and 57 spaces are
proposed as on-street parking. In addition, the applicant is proposing to work closely with PSE for the engineering and

capacity needs of the development in order to relocate the powerlines and utility switchgear adjacent to Johns Creek.
Vehicular access to Southport West would be provided by Park Ave N, Lake Washington Blvd N, and the addition of an
internal center road and frontage road.
The site is generally level and consists of gravel yard and asphalt, a Puget Sound Energy switchgear, and an
office/warehouse building. The site contains high seismic hazard areas and the northeast corner of the site contains
Johns Creek and regulated slopes. The soil consists of a loose to medium dense sand, underlain by soft to medium dense
silt, then medium dense to dense sand, very soft silt and clay, and finally dense to very dense silty sand. Groundwater
was observed in the historical exploration at Southport at depths ranging from 3 to 10 feet below existing grade.
Preliminary estimates of cut and fill include approximately 25,000 cubic yards of excavation and 39,200 cubic yards of fill
from an approved source. The depth of excavation is anticipated to not exceed approximately two feet (2’) below ground
level, except for building cores where excavation would be deeper. Stormwater runoff from pollution generating surfaces
would be captured by catch basins and treated in cartridge filter facilities prior to connection into three (3) existing
drainage systems. No significant trees are proposed to be removed. Southport is proposing to plant 115 new trees along
with a variety of shrubs and perennials. The applicant has submitted a Preliminary Geotechnical Report, Technical
Information Report, Traffic Impact Analysis, and Stream Assessment and Final Mitigation Plan with the application.

Vehicular access to Southport West would be provided by Park Ave N, Lake Washington Blvd N, and the addition of an
internal center road and frontage road.
The site is generally level and consists of gravel yard and asphalt, a Puget Sound Energy switchgear, and an
office/warehouse building. The site contains high seismic hazard areas and the northeast corner of the site contains
Johns Creek and regulated slopes. The soil consists of a loose to medium dense sand, underlain by soft to medium dense
silt, then medium dense to dense sand, very soft silt and clay, and finally dense to very dense silty sand. Groundwater
was observed in the historical exploration at Southport at depths ranging from 3 to 10 feet below existing grade.
Preliminary estimates of cut and fill include approximately 25,000 cubic yards of excavation and 39,200 cubic yards of fill
from an approved source. The depth of excavation is anticipated to not exceed approximately two feet (2’) below ground
level, except for building cores where excavation would be deeper. Stormwater runoff from pollution generating surfaces
would be captured by catch basins and treated in cartridge filter facilities prior to connection into three (3) existing
drainage systems. No significant trees are proposed to be removed. Southport is proposing to plant 115 new trees along
with a variety of shrubs and perennials. The applicant has submitted a Preliminary Geotechnical Report, Technical
Information Report, Traffic Impact Analysis, and Stream Assessment and Final Mitigation Plan with the application.

PROJECT DESCRIPTION: The applicant, Southport West LLC, is requesting Master Plan Review, Hearing Examiner
Site Plan Review and Environmental (SEPA) Review for the construction of Southport West. Southport West is the
completion of the southerly portion of the Southport Development located at the south end of Lake Washington Blvd N.
The proposed expansion of Southport would be located on the 10.09-acre former Puget Sound Energy (PSE) Substation
and PSE utility parcels (APNs 082305-9191 and -9178). The two (2) parcels are located in the Urban Center-2 (UC-2) zone
and the Urban Design District ‘C’. The site is proposed to be developed as five (5) high-rise buildings with approximately
1,200,000 square feet of office and 50,000 of retail development in multiple phases. The proposed first three phases
would be developed as follows: Phase I – Towers 1 and 2 with the garage podium (July 2023 – July 2027), Phase II –
Towers 3 and 4 with garage podium (July 2027 – July 2031), and Phase III – Tower 5 (post July 2031). Phases 1-3 would
start on the south side of the site (closer to Boeing) and would develop to the north side of the lot (closer to Gene Coulon
Memorial Beach Park). A fourth and final phase is being considered for a sixth tower with 130,000 square feet for office
and retail at the south corner of the development near the intersection of Park Ave N and 757th Ave NE. The phased
development could reach as high as 1.6 million gross square feet. The proposed nine-level development would be built
at the same height and scale as the existing Southport offices with an overall height of approximately 154 feet above
average grade. Parking for 2,207 vehicles would be provided in a shared 4- and 5-level parking garage and 57 spaces are
proposed as on-street parking. In addition, the applicant is proposing to work closely with PSE for the engineering and

capacity needs of the development in order to relocate the powerlines and utility switchgear adjacent to Johns Creek.
Vehicular access to Southport West would be provided by Park Ave N, Lake Washington Blvd N, and the addition of an
internal center road and frontage road.
The site is generally level and consists of gravel yard and asphalt, a Puget Sound Energy switchgear, and an
office/warehouse building. The site contains high seismic hazard areas and the northeast corner of the site contains
Johns Creek and regulated slopes. The soil consists of a loose to medium dense sand, underlain by soft to medium dense
silt, then medium dense to dense sand, very soft silt and clay, and finally dense to very dense silty sand. Groundwater
was observed in the historical exploration at Southport at depths ranging from 3 to 10 feet below existing grade.
Preliminary estimates of cut and fill include approximately 25,000 cubic yards of excavation and 39,200 cubic yards of fill
from an approved source. The depth of excavation is anticipated to not exceed approximately two feet (2’) below ground
level, except for building cores where excavation would be deeper. Stormwater runoff from pollution generating surfaces
would be captured by catch basins and treated in cartridge filter facilities prior to connection into three (3) existing
drainage systems. No significant trees are proposed to be removed. Southport is proposing to plant 115 new trees along
with a variety of shrubs and perennials. The applicant has submitted a Preliminary Geotechnical Report, Technical
Information Report, Traffic Impact Analysis, and Stream Assessment and Final Mitigation Plan with the application.

PROJECT DESCRIPTION: The applicant, Southport West LLC, is requesting Master Plan Review, Hearing Examiner
Site Plan Review and Environmental (SEPA) Review for the construction of Southport West. Southport West is the
completion of the southerly portion of the Southport Development located at the south end of Lake Washington Blvd N.
The proposed expansion of Southport would be located on the 10.09-acre former Puget Sound Energy (PSE) Substation
and PSE utility parcels (APNs 082305-9191 and -9178). The two (2) parcels are located in the Urban Center-2 (UC-2) zone
and the Urban Design District ‘C’. The site is proposed to be developed as five (5) high-rise buildings with approximately
1,200,000 square feet of office and 50,000 of retail development in multiple phases. The proposed first three phases
would be developed as follows: Phase I – Towers 1 and 2 with the garage podium (July 2023 – July 2027), Phase II –
Towers 3 and 4 with garage podium (July 2027 – July 2031), and Phase III – Tower 5 (post July 2031). Phases 1-3 would
start on the south side of the site (closer to Boeing) and would develop to the north side of the lot (closer to Gene Coulon
Memorial Beach Park). A fourth and final phase is being considered for a sixth tower with 130,000 square feet for office
and retail at the south corner of the development near the intersection of Park Ave N and 757th Ave NE. The phased
development could reach as high as 1.6 million gross square feet. The proposed nine-level development would be built
at the same height and scale as the existing Southport offices with an overall height of approximately 154 feet above
average grade. Parking for 2,207 vehicles would be provided in a shared 4- and 5-level parking garage and 57 spaces are
proposed as on-street parking. In addition, the applicant is proposing to work closely with PSE for the engineering and

capacity needs of the development in order to relocate the powerlines and utility switchgear adjacent to Johns Creek.
Vehicular access to Southport West would be provided by Park Ave N, Lake Washington Blvd N, and the addition of an
internal center road and frontage road.
The site is generally level and consists of gravel yard and asphalt, a Puget Sound Energy switchgear, and an
office/warehouse building. The site contains high seismic hazard areas and the northeast corner of the site contains
Johns Creek and regulated slopes. The soil consists of a loose to medium dense sand, underlain by soft to medium dense
silt, then medium dense to dense sand, very soft silt and clay, and finally dense to very dense silty sand. Groundwater
was observed in the historical exploration at Southport at depths ranging from 3 to 10 feet below existing grade.
Preliminary estimates of cut and fill include approximately 25,000 cubic yards of excavation and 39,200 cubic yards of fill
from an approved source. The depth of excavation is anticipated to not exceed approximately two feet (2’) below ground
level, except for building cores where excavation would be deeper. Stormwater runoff from pollution generating surfaces
would be captured by catch basins and treated in cartridge filter facilities prior to connection into three (3) existing
drainage systems. No significant trees are proposed to be removed. Southport is proposing to plant 115 new trees along
with a variety of shrubs and perennials. The applicant has submitted a Preliminary Geotechnical Report, Technical
Information Report, Traffic Impact Analysis, and Stream Assessment and Final Mitigation Plan with the application.

PROJECT DESCRIPTION: The applicant, Southport West LLC, is requesting Master Plan Review, Hearing Examiner
Site Plan Review and Environmental (SEPA) Review for the construction of Southport West. Southport West is the
completion of the southerly portion of the Southport Development located at the south end of Lake Washington Blvd N.
The proposed expansion of Southport would be located on the 10.09-acre former Puget Sound Energy (PSE) Substation
and PSE utility parcels (APNs 082305-9191 and -9178). The two (2) parcels are located in the Urban Center-2 (UC-2) zone
and the Urban Design District ‘C’. The site is proposed to be developed as five (5) high-rise buildings with approximately
1,200,000 square feet of office and 50,000 of retail development in multiple phases. The proposed first three phases
would be developed as follows: Phase I – Towers 1 and 2 with the garage podium (July 2023 – July 2027), Phase II –
Towers 3 and 4 with garage podium (July 2027 – July 2031), and Phase III – Tower 5 (post July 2031). Phases 1-3 would
start on the south side of the site (closer to Boeing) and would develop to the north side of the lot (closer to Gene Coulon
Memorial Beach Park). A fourth and final phase is being considered for a sixth tower with 130,000 square feet for office
and retail at the south corner of the development near the intersection of Park Ave N and 757th Ave NE. The phased
development could reach as high as 1.6 million gross square feet. The proposed nine-level development would be built
at the same height and scale as the existing Southport offices with an overall height of approximately 154 feet above
average grade. Parking for 2,207 vehicles would be provided in a shared 4- and 5-level parking garage and 57 spaces are
proposed as on-street parking. In addition, the applicant is proposing to work closely with PSE for the engineering and

Vehicular access to Southport West would be provided by Park Ave N, Lake Washington Blvd N, and the addition of an
internal center road and frontage road.
The site is generally level and consists of gravel yard and asphalt, a Puget Sound Energy switchgear, and an
office/warehouse building. The site contains high seismic hazard areas and the northeast corner of the site contains
Johns Creek and regulated slopes. The soil consists of a loose to medium dense sand, underlain by soft to medium dense
silt, then medium dense to dense sand, very soft silt and clay, and finally dense to very dense silty sand. Groundwater
was observed in the historical exploration at Southport at depths ranging from 3 to 10 feet below existing grade.
Preliminary estimates of cut and fill include approximately 25,000 cubic yards of excavation and 39,200 cubic yards of fill
from an approved source. The depth of excavation is anticipated to not exceed approximately two feet (2’) below ground
level, except for building cores where excavation would be deeper. Stormwater runoff from pollution generating surfaces
would be captured by catch basins and treated in cartridge filter facilities prior to connection into three (3) existing

PROJECT DESCRIPTION: The applicant, Southport West LLC, is requesting Master Plan Review, Hearing Examiner
Site Plan Review and Environmental (SEPA) Review for the construction of Southport West. Southport West is the
completion of the southerly portion of the Southport Development located at the south end of Lake Washington Blvd N.
The proposed expansion of Southport would be located on the 10.09-acre former Puget Sound Energy (PSE) Substation
and PSE utility parcels (APNs 082305-9191 and -9178). The two (2) parcels are located in the Urban Center-2 (UC-2) zone
and the Urban Design District ‘C’. The site is proposed to be developed as five (5) high-rise buildings with approximately
1,200,000 square feet of office and 50,000 of retail development in multiple phases. The proposed first three phases
would be developed as follows: Phase I – Towers 1 and 2 with the garage podium (July 2023 – July 2027), Phase II –
Towers 3 and 4 with garage podium (July 2027 – July 2031), and Phase III – Tower 5 (post July 2031). Phases 1-3 would
start on the south side of the site (closer to Boeing) and would develop to the north side of the lot (closer to Gene Coulon
Memorial Beach Park). A fourth and final phase is being considered for a sixth tower with 130,000 square feet for office
and retail at the south corner of the development near the intersection of Park Ave N and 757th Ave NE. The phased
development could reach as high as 1.6 million gross square feet. The proposed nine-level development would be built
at the same height and scale as the existing Southport offices with an overall height of approximately 154 feet above
average grade. Parking for 2,207 vehicles would be provided in a shared 4- and 5-level parking garage and 57 spaces are
proposed as on-street parking. In addition, the applicant is proposing to work closely with PSE for the engineering and

capacity needs of the development in order to relocate the powerlines and utility switchgear adjacent to Johns Creek.
Vehicular access to Southport West would be provided by Park Ave N, Lake Washington Blvd N, and the addition of an
internal center road and frontage road.
The site is generally level and consists of gravel yard and asphalt, a Puget Sound Energy switchgear, and an
office/warehouse building. The site contains high seismic hazard areas and the northeast corner of the site contains
Johns Creek and regulated slopes. The soil consists of a loose to medium dense sand, underlain by soft to medium dense
silt, then medium dense to dense sand, very soft silt and clay, and finally dense to very dense silty sand. Groundwater
was observed in the historical exploration at Southport at depths ranging from 3 to 10 feet below existing grade.
Preliminary estimates of cut and fill include approximately 25,000 cubic yards of excavation and 39,200 cubic yards of fill
from an approved source. The depth of excavation is anticipated to not exceed approximately two feet (2’) below ground
level, except for building cores where excavation would be deeper. Stormwater runoff from pollution generating surfaces
would be captured by catch basins and treated in cartridge filter facilities prior to connection into three (3) existing
drainage systems. No significant trees are proposed to be removed. Southport is proposing to plant 115 new trees along
with a variety of shrubs and perennials. The applicant has submitted a Preliminary Geotechnical Report, Technical
Information Report, Traffic Impact Analysis, and Stream Assessment and Final Mitigation Plan with the application.

capacity needs of the development in order to relocate the powerlines and utility switchgear adjacent to Johns Creek.
Vehicular access to Southport West would be provided by Park Ave N, Lake Washington Blvd N, and the addition of an
internal center road and frontage road.
The site is generally level and consists of gravel yard and asphalt, a Puget Sound Energy switchgear, and an
office/warehouse building. The site contains high seismic hazard areas and the northeast corner of the site contains
Johns Creek and regulated slopes. The soil consists of a loose to medium dense sand, underlain by soft to medium dense
silt, then medium dense to dense sand, very soft silt and clay, and finally dense to very dense silty sand. Groundwater
was observed in the historical exploration at Southport at depths ranging from 3 to 10 feet below existing grade.
Preliminary estimates of cut and fill include approximately 25,000 cubic yards of excavation and 39,200 cubic yards of fill
from an approved source. The depth of excavation is anticipated to not exceed approximately two feet (2’) below ground
level, except for building cores where excavation would be deeper. Stormwater runoff from pollution generating surfaces
would be captured by catch basins and treated in cartridge filter facilities prior to connection into three (3) existing
drainage systems. No significant trees are proposed to be removed. Southport is proposing to plant 115 new trees along
with a variety of shrubs and perennials. The applicant has submitted a Preliminary Geotechnical Report, Technical
Information Report, Traffic Impact Analysis, and Stream Assessment and Final Mitigation Plan with the application.

PROJECT DESCRIPTION: The applicant, Southport West LLC, is requesting Master Plan Review, Hearing Examiner
Site Plan Review and Environmental (SEPA) Review for the construction of Southport West. Southport West is the
completion of the southerly portion of the Southport Development located at the south end of Lake Washington Blvd N.
The proposed expansion of Southport would be located on the 10.09-acre former Puget Sound Energy (PSE) Substation
and PSE utility parcels (APNs 082305-9191 and -9178). The two (2) parcels are located in the Urban Center-2 (UC-2) zone
and the Urban Design District ‘C’. The site is proposed to be developed as five (5) high-rise buildings with approximately
1,200,000 square feet of office and 50,000 of retail development in multiple phases. The proposed first three phases
would be developed as follows: Phase I – Towers 1 and 2 with the garage podium (July 2023 – July 2027), Phase II –
Towers 3 and 4 with garage podium (July 2027 – July 2031), and Phase III – Tower 5 (post July 2031). Phases 1-3 would
start on the south side of the site (closer to Boeing) and would develop to the north side of the lot (closer to Gene Coulon
Memorial Beach Park). A fourth and final phase is being considered for a sixth tower with 130,000 square feet for office
and retail at the south corner of the development near the intersection of Park Ave N and 757th Ave NE. The phased
development could reach as high as 1.6 million gross square feet. The proposed nine-level development would be built
at the same height and scale as the existing Southport offices with an overall height of approximately 154 feet above
average grade. Parking for 2,207 vehicles would be provided in a shared 4- and 5-level parking garage and 57 spaces are
proposed as on-street parking. In addition, the applicant is proposing to work closely with PSE for the engineering and

PROJECT DESCRIPTION: The applicant, Southport West LLC, is requesting Master Plan Review, Hearing Examiner
Site Plan Review and Environmental (SEPA) Review for the construction of Southport West. Southport West is the
completion of the southerly portion of the Southport Development located at the south end of Lake Washington Blvd N.
The proposed expansion of Southport would be located on the 10.09-acre former Puget Sound Energy (PSE) Substation
and PSE utility parcels (APNs 082305-9191 and -9178). The two (2) parcels are located in the Urban Center-2 (UC-2) zone
and the Urban Design District ‘C’. The site is proposed to be developed as five (5) high-rise buildings with approximately
1,200,000 square feet of office and 50,000 of retail development in multiple phases. The proposed first three phases
would be developed as follows: Phase I – Towers 1 and 2 with the garage podium (July 2023 – July 2027), Phase II –
Towers 3 and 4 with garage podium (July 2027 – July 2031), and Phase III – Tower 5 (post July 2031). Phases 1-3 would
start on the south side of the site (closer to Boeing) and would develop to the north side of the lot (closer to Gene Coulon
Memorial Beach Park). A fourth and final phase is being considered for a sixth tower with 130,000 square feet for office
and retail at the south corner of the development near the intersection of Park Ave N and 757th Ave NE. The phased
development could reach as high as 1.6 million gross square feet. The proposed nine-level development would be built
at the same height and scale as the existing Southport offices with an overall height of approximately 154 feet above
average grade. Parking for 2,207 vehicles would be provided in a shared 4- and 5-level parking garage and 57 spaces are
proposed as on-street parking. In addition, the applicant is proposing to work closely with PSE for the engineering and

capacity needs of the development in order to relocate the powerlines and utility switchgear adjacent to Johns Creek.
Vehicular access to Southport West would be provided by Park Ave N, Lake Washington Blvd N, and the addition of an
internal center road and frontage road.
The site is generally level and consists of gravel yard and asphalt, a Puget Sound Energy switchgear, and an
office/warehouse building. The site contains high seismic hazard areas and the northeast corner of the site contains
Johns Creek and regulated slopes. The soil consists of a loose to medium dense sand, underlain by soft to medium dense
silt, then medium dense to dense sand, very soft silt and clay, and finally dense to very dense silty sand. Groundwater
was observed in the historical exploration at Southport at depths ranging from 3 to 10 feet below existing grade.
Preliminary estimates of cut and fill include approximately 25,000 cubic yards of excavation and 39,200 cubic yards of fill
from an approved source. The depth of excavation is anticipated to not exceed approximately two feet (2’) below ground
level, except for building cores where excavation would be deeper. Stormwater runoff from pollution generating surfaces
would be captured by catch basins and treated in cartridge filter facilities prior to connection into three (3) existing
drainage systems. No significant trees are proposed to be removed. Southport is proposing to plant 115 new trees along
with a variety of shrubs and perennials. The applicant has submitted a Preliminary Geotechnical Report, Technical
Information Report, Traffic Impact Analysis, and Stream Assessment and Final Mitigation Plan with the application.

Towers 3 and 4 with garage podium (July 2027 – July 2031), and Phase III – Tower 5 (post July 2031). Phases 1-3 would
start on the south side of the site (closer to Boeing) and would develop to the north side of the lot (closer to Gene Coulon
Memorial Beach Park). A fourth and final phase is being considered for a sixth tower with 130,000 square feet for office
and retail at the south corner of the development near the intersection of Park Ave N and 757th Ave NE. The phased
development could reach as high as 1.6 million gross square feet. The proposed nine-level development would be built
at the same height and scale as the existing Southport offices with an overall height of approximately 154 feet above
average grade. Parking for 2,207 vehicles would be provided in a shared 4- and 5-level parking garage and 57 spaces are
proposed as on-street parking. In addition, the applicant is proposing to work closely with PSE for the engineering and

Vehicular access to Southport West would be provided by Park Ave N, Lake Washington Blvd N, and the addition of an
internal center road and frontage road.
The site is generally level and consists of gravel yard and asphalt, a Puget Sound Energy switchgear, and an
office/warehouse building. The site contains high seismic hazard areas and the northeast corner of the site contains
Johns Creek and regulated slopes. The soil consists of a loose to medium dense sand, underlain by soft to medium dense
silt, then medium dense to dense sand, very soft silt and clay, and finally dense to very dense silty sand. Groundwater
was observed in the historical exploration at Southport at depths ranging from 3 to 10 feet below existing grade.
Preliminary estimates of cut and fill include approximately 25,000 cubic yards of excavation and 39,200 cubic yards of fill
from an approved source. The depth of excavation is anticipated to not exceed approximately two feet (2’) below ground
level, except for building cores where excavation would be deeper. Stormwater runoff from pollution generating surfaces
would be captured by catch basins and treated in cartridge filter facilities prior to connection into three (3) existing
drainage systems. No significant trees are proposed to be removed. Southport is proposing to plant 115 new trees along
with a variety of shrubs and perennials. The applicant has submitted a Preliminary Geotechnical Report, Technical
Information Report, Traffic Impact Analysis, and Stream Assessment and Final Mitigation Plan with the application.

PROJECT DESCRIPTION: The applicant, Southport West LLC, is requesting Master Plan Review, Hearing Examiner
Site Plan Review and Environmental (SEPA) Review for the construction of Southport West. Southport West is the
completion of the southerly portion of the Southport Development located at the south end of Lake Washington Blvd N.
The proposed expansion of Southport would be located on the 10.09-acre former Puget Sound Energy (PSE) Substation
and PSE utility parcels (APNs 082305-9191 and -9178). The two (2) parcels are located in the Urban Center-2 (UC-2) zone
and the Urban Design District ‘C’. The site is proposed to be developed as five (5) high-rise buildings with approximately
1,200,000 square feet of office and 50,000 of retail development in multiple phases. The proposed first three phases
would be developed as follows: Phase I – Towers 1 and 2 with the garage podium (July 2023 – July 2027), Phase II –
Towers 3 and 4 with garage podium (July 2027 – July 2031), and Phase III – Tower 5 (post July 2031). Phases 1-3 would
start on the south side of the site (closer to Boeing) and would develop to the north side of the lot (closer to Gene Coulon
Memorial Beach Park). A fourth and final phase is being considered for a sixth tower with 130,000 square feet for office
and retail at the south corner of the development near the intersection of Park Ave N and 757th Ave NE. The phased
development could reach as high as 1.6 million gross square feet. The proposed nine-level development would be built
at the same height and scale as the existing Southport offices with an overall height of approximately 154 feet above
average grade. Parking for 2,207 vehicles would be provided in a shared 4- and 5-level parking garage and 57 spaces are
proposed as on-street parking. In addition, the applicant is proposing to work closely with PSE for the engineering and

capacity needs of the development in order to relocate the powerlines and utility switchgear adjacent to Johns Creek.
Vehicular access to Southport West would be provided by Park Ave N, Lake Washington Blvd N, and the addition of an
internal center road and frontage road.
The site is generally level and consists of gravel yard and asphalt, a Puget Sound Energy switchgear, and an
office/warehouse building. The site contains high seismic hazard areas and the northeast corner of the site contains
Johns Creek and regulated slopes. The soil consists of a loose to medium dense sand, underlain by soft to medium dense
silt, then medium dense to dense sand, very soft silt and clay, and finally dense to very dense silty sand. Groundwater
was observed in the historical exploration at Southport at depths ranging from 3 to 10 feet below existing grade.
Preliminary estimates of cut and fill include approximately 25,000 cubic yards of excavation and 39,200 cubic yards of fill
from an approved source. The depth of excavation is anticipated to not exceed approximately two feet (2’) below ground
level, except for building cores where excavation would be deeper. Stormwater runoff from pollution generating surfaces
would be captured by catch basins and treated in cartridge filter facilities prior to connection into three (3) existing
drainage systems. No significant trees are proposed to be removed. Southport is proposing to plant 115 new trees along
with a variety of shrubs and perennials. The applicant has submitted a Preliminary Geotechnical Report, Technical
Information Report, Traffic Impact Analysis, and Stream Assessment and Final Mitigation Plan with the application.

PROJECT DESCRIPTION: The applicant, Southport West LLC, is requesting Master Plan Review, Hearing Examiner
Site Plan Review and Environmental (SEPA) Review for the construction of Southport West. Southport West is the
completion of the southerly portion of the Southport Development located at the south end of Lake Washington Blvd N.
The proposed expansion of Southport would be located on the 10.09-acre former Puget Sound Energy (PSE) Substation
and PSE utility parcels (APNs 082305-9191 and -9178). The two (2) parcels are located in the Urban Center-2 (UC-2) zone
and the Urban Design District ‘C’. The site is proposed to be developed as five (5) high-rise buildings with approximately
1,200,000 square feet of office and 50,000 of retail development in multiple phases. The proposed first three phases
would be developed as follows: Phase I – Towers 1 and 2 with the garage podium (July 2023 – July 2027), Phase II –
Towers 3 and 4 with garage podium (July 2027 – July 2031), and Phase III – Tower 5 (post July 2031). Phases 1-3 would
start on the south side of the site (closer to Boeing) and would develop to the north side of the lot (closer to Gene Coulon
Memorial Beach Park). A fourth and final phase is being considered for a sixth tower with 130,000 square feet for office
and retail at the south corner of the development near the intersection of Park Ave N and 757th Ave NE. The phased
development could reach as high as 1.6 million gross square feet. The proposed nine-level development would be built
at the same height and scale as the existing Southport offices with an overall height of approximately 154 feet above
average grade. Parking for 2,207 vehicles would be provided in a shared 4- and 5-level parking garage and 57 spaces are
proposed as on-street parking. In addition, the applicant is proposing to work closely with PSE for the engineering and

capacity needs of the development in order to relocate the powerlines and utility switchgear adjacent to Johns Creek.
Vehicular access to Southport West would be provided by Park Ave N, Lake Washington Blvd N, and the addition of an
internal center road and frontage road.
The site is generally level and consists of gravel yard and asphalt, a Puget Sound Energy switchgear, and an
office/warehouse building. The site contains high seismic hazard areas and the northeast corner of the site contains
Johns Creek and regulated slopes. The soil consists of a loose to medium dense sand, underlain by soft to medium dense
silt, then medium dense to dense sand, very soft silt and clay, and finally dense to very dense silty sand. Groundwater
was observed in the historical exploration at Southport at depths ranging from 3 to 10 feet below existing grade.
Preliminary estimates of cut and fill include approximately 25,000 cubic yards of excavation and 39,200 cubic yards of fill
from an approved source. The depth of excavation is anticipated to not exceed approximately two feet (2’) below ground
level, except for building cores where excavation would be deeper. Stormwater runoff from pollution generating surfaces
would be captured by catch basins and treated in cartridge filter facilities prior to connection into three (3) existing
drainage systems. No significant trees are proposed to be removed. Southport is proposing to plant 115 new trees along
with a variety of shrubs and perennials. The applicant has submitted a Preliminary Geotechnical Report, Technical
Information Report, Traffic Impact Analysis, and Stream Assessment and Final Mitigation Plan with the application.

office/warehouse building. The site contains high seismic hazard areas and the northeast corner of the site contains
Johns Creek and regulated slopes. The soil consists of a loose to medium dense sand, underlain by soft to medium dense
silt, then medium dense to dense sand, very soft silt and clay, and finally dense to very dense silty sand. Groundwater
was observed in the historical exploration at Southport at depths ranging from 3 to 10 feet below existing grade.
Preliminary estimates of cut and fill include approximately 25,000 cubic yards of excavation and 39,200 cubic yards of fill
from an approved source. The depth of excavation is anticipated to not exceed approximately two feet (2’) below ground
level, except for building cores where excavation would be deeper. Stormwater runoff from pollution generating surfaces
would be captured by catch basins and treated in cartridge filter facilities prior to connection into three (3) existing
drainage systems. No significant trees are proposed to be removed. Southport is proposing to plant 115 new trees along
with a variety of shrubs and perennials. The applicant has submitted a Preliminary Geotechnical Report, Technical
Information Report, Traffic Impact Analysis, and Stream Assessment and Final Mitigation Plan with the application.

Site Plan Review and Environmental (SEPA) Review for the construction of Southport West. Southport West is the
completion of the southerly portion of the Southport Development located at the south end of Lake Washington Blvd N.
The proposed expansion of Southport would be located on the 10.09-acre former Puget Sound Energy (PSE) Substation
and PSE utility parcels (APNs 082305-9191 and -9178). The two (2) parcels are located in the Urban Center-2 (UC-2) zone
and the Urban Design District ‘C’. The site is proposed to be developed as five (5) high-rise buildings with approximately
1,200,000 square feet of office and 50,000 of retail development in multiple phases. The proposed first three phases
would be developed as follows: Phase I – Towers 1 and 2 with the garage podium (July 2023 – July 2027), Phase II –
Towers 3 and 4 with garage podium (July 2027 – July 2031), and Phase III – Tower 5 (post July 2031). Phases 1-3 would
start on the south side of the site (closer to Boeing) and would develop to the north side of the lot (closer to Gene Coulon
Memorial Beach Park). A fourth and final phase is being considered for a sixth tower with 130,000 square feet for office
and retail at the south corner of the development near the intersection of Park Ave N and 757th Ave NE. The phased
development could reach as high as 1.6 million gross square feet. The proposed nine-level development would be built
at the same height and scale as the existing Southport offices with an overall height of approximately 154 feet above
average grade. Parking for 2,207 vehicles would be provided in a shared 4- and 5-level parking garage and 57 spaces are
proposed as on-street parking. In addition, the applicant is proposing to work closely with PSE for the engineering and

PROJECT DESCRIPTION: The applicant, Southport West LLC, is requesting Master Plan Review, Hearing Examiner
Site Plan Review and Environmental (SEPA) Review for the construction of Southport West. Southport West is the
completion of the southerly portion of the Southport Development located at the south end of Lake Washington Blvd N.
The proposed expansion of Southport would be located on the 10.09-acre former Puget Sound Energy (PSE) Substation
and PSE utility parcels (APNs 082305-9191 and -9178). The two (2) parcels are located in the Urban Center-2 (UC-2) zone
and the Urban Design District ‘C’. The site is proposed to be developed as five (5) high-rise buildings with approximately
1,200,000 square feet of office and 50,000 of retail development in multiple phases. The proposed first three phases
would be developed as follows: Phase I – Towers 1 and 2 with the garage podium (July 2023 – July 2027), Phase II –
Towers 3 and 4 with garage podium (July 2027 – July 2031), and Phase III – Tower 5 (post July 2031). Phases 1-3 would
start on the south side of the site (closer to Boeing) and would develop to the north side of the lot (closer to Gene Coulon
Memorial Beach Park). A fourth and final phase is being considered for a sixth tower with 130,000 square feet for office
and retail at the south corner of the development near the intersection of Park Ave N and 757th Ave NE. The phased
development could reach as high as 1.6 million gross square feet. The proposed nine-level development would be built
at the same height and scale as the existing Southport offices with an overall height of approximately 154 feet above
average grade. Parking for 2,207 vehicles would be provided in a shared 4- and 5-level parking garage and 57 spaces are
proposed as on-street parking. In addition, the applicant is proposing to work closely with PSE for the engineering and

capacity needs of the development in order to relocate the powerlines and utility switchgear adjacent to Johns Creek.
Vehicular access to Southport West would be provided by Park Ave N, Lake Washington Blvd N, and the addition of an
internal center road and frontage road.
The site is generally level and consists of gravel yard and asphalt, a Puget Sound Energy switchgear, and an
office/warehouse building. The site contains high seismic hazard areas and the northeast corner of the site contains
Johns Creek and regulated slopes. The soil consists of a loose to medium dense sand, underlain by soft to medium dense
silt, then medium dense to dense sand, very soft silt and clay, and finally dense to very dense silty sand. Groundwater
was observed in the historical exploration at Southport at depths ranging from 3 to 10 feet below existing grade.
Preliminary estimates of cut and fill include approximately 25,000 cubic yards of excavation and 39,200 cubic yards of fill
from an approved source. The depth of excavation is anticipated to not exceed approximately two feet (2’) below ground
level, except for building cores where excavation would be deeper. Stormwater runoff from pollution generating surfaces
would be captured by catch basins and treated in cartridge filter facilities prior to connection into three (3) existing
drainage systems. No significant trees are proposed to be removed. Southport is proposing to plant 115 new trees along
with a variety of shrubs and perennials. The applicant has submitted a Preliminary Geotechnical Report, Technical
Information Report, Traffic Impact Analysis, and Stream Assessment and Final Mitigation Plan with the application.

capacity needs of the development in order to relocate the powerlines and utility switchgear adjacent to Johns Creek.
Vehicular access to Southport West would be provided by Park Ave N, Lake Washington Blvd N, and the addition of an
internal center road and frontage road.
The site is generally level and consists of gravel yard and asphalt, a Puget Sound Energy switchgear, and an
office/warehouse building. The site contains high seismic hazard areas and the northeast corner of the site contains
Johns Creek and regulated slopes. The soil consists of a loose to medium dense sand, underlain by soft to medium dense
silt, then medium dense to dense sand, very soft silt and clay, and finally dense to very dense silty sand. Groundwater
was observed in the historical exploration at Southport at depths ranging from 3 to 10 feet below existing grade.
Preliminary estimates of cut and fill include approximately 25,000 cubic yards of excavation and 39,200 cubic yards of fill
from an approved source. The depth of excavation is anticipated to not exceed approximately two feet (2’) below ground
level, except for building cores where excavation would be deeper. Stormwater runoff from pollution generating surfaces
would be captured by catch basins and treated in cartridge filter facilities prior to connection into three (3) existing
drainage systems. No significant trees are proposed to be removed. Southport is proposing to plant 115 new trees along
with a variety of shrubs and perennials. The applicant has submitted a Preliminary Geotechnical Report, Technical
Information Report, Traffic Impact Analysis, and Stream Assessment and Final Mitigation Plan with the application.

The proposed expansion of Southport would be located on the 10.09-acre former Puget Sound Energy (PSE) Substation
and PSE utility parcels (APNs 082305-9191 and -9178). The two (2) parcels are located in the Urban Center-2 (UC-2) zone
and the Urban Design District ‘C’. The site is proposed to be developed as five (5) high-rise buildings with approximately
1,200,000 square feet of office and 50,000 of retail development in multiple phases. The proposed first three phases
would be developed as follows: Phase I – Towers 1 and 2 with the garage podium (July 2023 – July 2027), Phase II –
Towers 3 and 4 with garage podium (July 2027 – July 2031), and Phase III – Tower 5 (post July 2031). Phases 1-3 would
start on the south side of the site (closer to Boeing) and would develop to the north side of the lot (closer to Gene Coulon
Memorial Beach Park). A fourth and final phase is being considered for a sixth tower with 130,000 square feet for office
and retail at the south corner of the development near the intersection of Park Ave N and 757th Ave NE. The phased
development could reach as high as 1.6 million gross square feet. The proposed nine-level development would be built
at the same height and scale as the existing Southport offices with an overall height of approximately 154 feet above
average grade. Parking for 2,207 vehicles would be provided in a shared 4- and 5-level parking garage and 57 spaces are

PROJECT DESCRIPTION: The applicant, Southport West LLC, is requesting Master Plan Review, Hearing Examiner
Site Plan Review and Environmental (SEPA) Review for the construction of Southport West. Southport West is the
completion of the southerly portion of the Southport Development located at the south end of Lake Washington Blvd N.
The proposed expansion of Southport would be located on the 10.09-acre former Puget Sound Energy (PSE) Substation
and PSE utility parcels (APNs 082305-9191 and -9178). The two (2) parcels are located in the Urban Center-2 (UC-2) zone
and the Urban Design District ‘C’. The site is proposed to be developed as five (5) high-rise buildings with approximately
1,200,000 square feet of office and 50,000 of retail development in multiple phases. The proposed first three phases
would be developed as follows: Phase I – Towers 1 and 2 with the garage podium (July 2023 – July 2027), Phase II –
Towers 3 and 4 with garage podium (July 2027 – July 2031), and Phase III – Tower 5 (post July 2031). Phases 1-3 would
start on the south side of the site (closer to Boeing) and would develop to the north side of the lot (closer to Gene Coulon
Memorial Beach Park). A fourth and final phase is being considered for a sixth tower with 130,000 square feet for office
and retail at the south corner of the development near the intersection of Park Ave N and 757th Ave NE. The phased
development could reach as high as 1.6 million gross square feet. The proposed nine-level development would be built
at the same height and scale as the existing Southport offices with an overall height of approximately 154 feet above
average grade. Parking for 2,207 vehicles would be provided in a shared 4- and 5-level parking garage and 57 spaces are
proposed as on-street parking. In addition, the applicant is proposing to work closely with PSE for the engineering and

capacity needs of the development in order to relocate the powerlines and utility switchgear adjacent to Johns Creek.
Vehicular access to Southport West would be provided by Park Ave N, Lake Washington Blvd N, and the addition of an
internal center road and frontage road.
The site is generally level and consists of gravel yard and asphalt, a Puget Sound Energy switchgear, and an
office/warehouse building. The site contains high seismic hazard areas and the northeast corner of the site contains
Johns Creek and regulated slopes. The soil consists of a loose to medium dense sand, underlain by soft to medium dense
silt, then medium dense to dense sand, very soft silt and clay, and finally dense to very dense silty sand. Groundwater
was observed in the historical exploration at Southport at depths ranging from 3 to 10 feet below existing grade.
Preliminary estimates of cut and fill include approximately 25,000 cubic yards of excavation and 39,200 cubic yards of fill
from an approved source. The depth of excavation is anticipated to not exceed approximately two feet (2’) below ground
level, except for building cores where excavation would be deeper. Stormwater runoff from pollution generating surfaces
would be captured by catch basins and treated in cartridge filter facilities prior to connection into three (3) existing
drainage systems. No significant trees are proposed to be removed. Southport is proposing to plant 115 new trees along
with a variety of shrubs and perennials. The applicant has submitted a Preliminary Geotechnical Report, Technical
Information Report, Traffic Impact Analysis, and Stream Assessment and Final Mitigation Plan with the application.

and PSE utility parcels (APNs 082305-9191 and -9178). The two (2) parcels are located in the Urban Center-2 (UC-2) zone
and the Urban Design District ‘C’. The site is proposed to be developed as five (5) high-rise buildings with approximately
1,200,000 square feet of office and 50,000 of retail development in multiple phases. The proposed first three phases
would be developed as follows: Phase I – Towers 1 and 2 with the garage podium (July 2023 – July 2027), Phase II –
Towers 3 and 4 with garage podium (July 2027 – July 2031), and Phase III – Tower 5 (post July 2031). Phases 1-3 would
start on the south side of the site (closer to Boeing) and would develop to the north side of the lot (closer to Gene Coulon
Memorial Beach Park). A fourth and final phase is being considered for a sixth tower with 130,000 square feet for office
and retail at the south corner of the development near the intersection of Park Ave N and 757th Ave NE. The phased
development could reach as high as 1.6 million gross square feet. The proposed nine-level development would be built
at the same height and scale as the existing Southport offices with an overall height of approximately 154 feet above
average grade. Parking for 2,207 vehicles would be provided in a shared 4- and 5-level parking garage and 57 spaces are
proposed as on-street parking. In addition, the applicant is proposing to work closely with PSE for the engineering and

capacity needs of the development in order to relocate the powerlines and utility switchgear adjacent to Johns Creek.
Vehicular access to Southport West would be provided by Park Ave N, Lake Washington Blvd N, and the addition of an
internal center road and frontage road.
The site is generally level and consists of gravel yard and asphalt, a Puget Sound Energy switchgear, and an
office/warehouse building. The site contains high seismic hazard areas and the northeast corner of the site contains
Johns Creek and regulated slopes. The soil consists of a loose to medium dense sand, underlain by soft to medium dense
silt, then medium dense to dense sand, very soft silt and clay, and finally dense to very dense silty sand. Groundwater
was observed in the historical exploration at Southport at depths ranging from 3 to 10 feet below existing grade.
Preliminary estimates of cut and fill include approximately 25,000 cubic yards of excavation and 39,200 cubic yards of fill
from an approved source. The depth of excavation is anticipated to not exceed approximately two feet (2’) below ground
level, except for building cores where excavation would be deeper. Stormwater runoff from pollution generating surfaces
would be captured by catch basins and treated in cartridge filter facilities prior to connection into three (3) existing
drainage systems. No significant trees are proposed to be removed. Southport is proposing to plant 115 new trees along
with a variety of shrubs and perennials. The applicant has submitted a Preliminary Geotechnical Report, Technical
Information Report, Traffic Impact Analysis, and Stream Assessment and Final Mitigation Plan with the application.

PROJECT DESCRIPTION: The applicant, Southport West LLC, is requesting Master Plan Review, Hearing Examiner
Site Plan Review and Environmental (SEPA) Review for the construction of Southport West. Southport West is the
completion of the southerly portion of the Southport Development located at the south end of Lake Washington Blvd N.
The proposed expansion of Southport would be located on the 10.09-acre former Puget Sound Energy (PSE) Substation
and PSE utility parcels (APNs 082305-9191 and -9178). The two (2) parcels are located in the Urban Center-2 (UC-2) zone
and the Urban Design District ‘C’. The site is proposed to be developed as five (5) high-rise buildings with approximately
1,200,000 square feet of office and 50,000 of retail development in multiple phases. The proposed first three phases
would be developed as follows: Phase I – Towers 1 and 2 with the garage podium (July 2023 – July 2027), Phase II –
Towers 3 and 4 with garage podium (July 2027 – July 2031), and Phase III – Tower 5 (post July 2031). Phases 1-3 would
start on the south side of the site (closer to Boeing) and would develop to the north side of the lot (closer to Gene Coulon
Memorial Beach Park). A fourth and final phase is being considered for a sixth tower with 130,000 square feet for office
and retail at the south corner of the development near the intersection of Park Ave N and 757th Ave NE. The phased
development could reach as high as 1.6 million gross square feet. The proposed nine-level development would be built
at the same height and scale as the existing Southport offices with an overall height of approximately 154 feet above
average grade. Parking for 2,207 vehicles would be provided in a shared 4- and 5-level parking garage and 57 spaces are
proposed as on-street parking. In addition, the applicant is proposing to work closely with PSE for the engineering and

Vehicular access to Southport West would be provided by Park Ave N, Lake Washington Blvd N, and the addition of an
internal center road and frontage road.
The site is generally level and consists of gravel yard and asphalt, a Puget Sound Energy switchgear, and an
office/warehouse building. The site contains high seismic hazard areas and the northeast corner of the site contains
Johns Creek and regulated slopes. The soil consists of a loose to medium dense sand, underlain by soft to medium dense
silt, then medium dense to dense sand, very soft silt and clay, and finally dense to very dense silty sand. Groundwater
was observed in the historical exploration at Southport at depths ranging from 3 to 10 feet below existing grade.
Preliminary estimates of cut and fill include approximately 25,000 cubic yards of excavation and 39,200 cubic yards of fill
from an approved source. The depth of excavation is anticipated to not exceed approximately two feet (2’) below ground
level, except for building cores where excavation would be deeper. Stormwater runoff from pollution generating surfaces
would be captured by catch basins and treated in cartridge filter facilities prior to connection into three (3) existing
drainage systems. No significant trees are proposed to be removed. Southport is proposing to plant 115 new trees along
with a variety of shrubs and perennials. The applicant has submitted a Preliminary Geotechnical Report, Technical
Information Report, Traffic Impact Analysis, and Stream Assessment and Final Mitigation Plan with the application.

PROJECT DESCRIPTION: The applicant, Southport West LLC, is requesting Master Plan Review, Hearing Examiner
Site Plan Review and Environmental (SEPA) Review for the construction of Southport West. Southport West is the
completion of the southerly portion of the Southport Development located at the south end of Lake Washington Blvd N.
The proposed expansion of Southport would be located on the 10.09-acre former Puget Sound Energy (PSE) Substation
and PSE utility parcels (APNs 082305-9191 and -9178). The two (2) parcels are located in the Urban Center-2 (UC-2) zone
and the Urban Design District ‘C’. The site is proposed to be developed as five (5) high-rise buildings with approximately
1,200,000 square feet of office and 50,000 of retail development in multiple phases. The proposed first three phases
would be developed as follows: Phase I – Towers 1 and 2 with the garage podium (July 2023 – July 2027), Phase II –
Towers 3 and 4 with garage podium (July 2027 – July 2031), and Phase III – Tower 5 (post July 2031). Phases 1-3 would
start on the south side of the site (closer to Boeing) and would develop to the north side of the lot (closer to Gene Coulon
Memorial Beach Park). A fourth and final phase is being considered for a sixth tower with 130,000 square feet for office
and retail at the south corner of the development near the intersection of Park Ave N and 757th Ave NE. The phased
development could reach as high as 1.6 million gross square feet. The proposed nine-level development would be built
at the same height and scale as the existing Southport offices with an overall height of approximately 154 feet above
average grade. Parking for 2,207 vehicles would be provided in a shared 4- and 5-level parking garage and 57 spaces are
proposed as on-street parking. In addition, the applicant is proposing to work closely with PSE for the engineering and

capacity needs of the development in order to relocate the powerlines and utility switchgear adjacent to Johns Creek.
Vehicular access to Southport West would be provided by Park Ave N, Lake Washington Blvd N, and the addition of an
internal center road and frontage road.
The site is generally level and consists of gravel yard and asphalt, a Puget Sound Energy switchgear, and an
office/warehouse building. The site contains high seismic hazard areas and the northeast corner of the site contains
Johns Creek and regulated slopes. The soil consists of a loose to medium dense sand, underlain by soft to medium dense
silt, then medium dense to dense sand, very soft silt and clay, and finally dense to very dense silty sand. Groundwater
was observed in the historical exploration at Southport at depths ranging from 3 to 10 feet below existing grade.
Preliminary estimates of cut and fill include approximately 25,000 cubic yards of excavation and 39,200 cubic yards of fill
from an approved source. The depth of excavation is anticipated to not exceed approximately two feet (2’) below ground
level, except for building cores where excavation would be deeper. Stormwater runoff from pollution generating surfaces
would be captured by catch basins and treated in cartridge filter facilities prior to connection into three (3) existing
drainage systems. No significant trees are proposed to be removed. Southport is proposing to plant 115 new trees along
with a variety of shrubs and perennials. The applicant has submitted a Preliminary Geotechnical Report, Technical
Information Report, Traffic Impact Analysis, and Stream Assessment and Final Mitigation Plan with the application.

capacity needs of the development in order to relocate the powerlines and utility switchgear adjacent to Johns Creek.
Vehicular access to Southport West would be provided by Park Ave N, Lake Washington Blvd N, and the addition of an
internal center road and frontage road.
The site is generally level and consists of gravel yard and asphalt, a Puget Sound Energy switchgear, and an
office/warehouse building. The site contains high seismic hazard areas and the northeast corner of the site contains
Johns Creek and regulated slopes. The soil consists of a loose to medium dense sand, underlain by soft to medium dense
silt, then medium dense to dense sand, very soft silt and clay, and finally dense to very dense silty sand. Groundwater
was observed in the historical exploration at Southport at depths ranging from 3 to 10 feet below existing grade.
Preliminary estimates of cut and fill include approximately 25,000 cubic yards of excavation and 39,200 cubic yards of fill
from an approved source. The depth of excavation is anticipated to not exceed approximately two feet (2’) below ground
level, except for building cores where excavation would be deeper. Stormwater runoff from pollution generating surfaces
would be captured by catch basins and treated in cartridge filter facilities prior to connection into three (3) existing
drainage systems. No significant trees are proposed to be removed. Southport is proposing to plant 115 new trees along
with a variety of shrubs and perennials. The applicant has submitted a Preliminary Geotechnical Report, Technical
Information Report, Traffic Impact Analysis, and Stream Assessment and Final Mitigation Plan with the application.

Site Plan Review and Environmental (SEPA) Review for the construction of Southport West. Southport West is the
completion of the southerly portion of the Southport Development located at the south end of Lake Washington Blvd N.
The proposed expansion of Southport would be located on the 10.09-acre former Puget Sound Energy (PSE) Substation
and PSE utility parcels (APNs 082305-9191 and -9178). The two (2) parcels are located in the Urban Center-2 (UC-2) zone
and the Urban Design District ‘C’. The site is proposed to be developed as five (5) high-rise buildings with approximately
1,200,000 square feet of office and 50,000 of retail development in multiple phases. The proposed first three phases
would be developed as follows: Phase I – Towers 1 and 2 with the garage podium (July 2023 – July 2027), Phase II –
Towers 3 and 4 with garage podium (July 2027 – July 2031), and Phase III – Tower 5 (post July 2031). Phases 1-3 would
start on the south side of the site (closer to Boeing) and would develop to the north side of the lot (closer to Gene Coulon
Memorial Beach Park). A fourth and final phase is being considered for a sixth tower with 130,000 square feet for office
and retail at the south corner of the development near the intersection of Park Ave N and 757th Ave NE. The phased
development could reach as high as 1.6 million gross square feet. The proposed nine-level development would be built
at the same height and scale as the existing Southport offices with an overall height of approximately 154 feet above
average grade. Parking for 2,207 vehicles would be provided in a shared 4- and 5-level parking garage and 57 spaces are
proposed as on-street parking. In addition, the applicant is proposing to work closely with PSE for the engineering and

PROJECT DESCRIPTION: The applicant, Southport West LLC, is requesting Master Plan Review, Hearing Examiner
Site Plan Review and Environmental (SEPA) Review for the construction of Southport West. Southport West is the
completion of the southerly portion of the Southport Development located at the south end of Lake Washington Blvd N.
The proposed expansion of Southport would be located on the 10.09-acre former Puget Sound Energy (PSE) Substation
and PSE utility parcels (APNs 082305-9191 and -9178). The two (2) parcels are located in the Urban Center-2 (UC-2) zone
and the Urban Design District ‘C’. The site is proposed to be developed as five (5) high-rise buildings with approximately
1,200,000 square feet of office and 50,000 of retail development in multiple phases. The proposed first three phases
would be developed as follows: Phase I – Towers 1 and 2 with the garage podium (July 2023 – July 2027), Phase II –
Towers 3 and 4 with garage podium (July 2027 – July 2031), and Phase III – Tower 5 (post July 2031). Phases 1-3 would
start on the south side of the site (closer to Boeing) and would develop to the north side of the lot (closer to Gene Coulon
Memorial Beach Park). A fourth and final phase is being considered for a sixth tower with 130,000 square feet for office
and retail at the south corner of the development near the intersection of Park Ave N and 757th Ave NE. The phased
development could reach as high as 1.6 million gross square feet. The proposed nine-level development would be built
at the same height and scale as the existing Southport offices with an overall height of approximately 154 feet above
average grade. Parking for 2,207 vehicles would be provided in a shared 4- and 5-level parking garage and 57 spaces are
proposed as on-street parking. In addition, the applicant is proposing to work closely with PSE for the engineering and

capacity needs of the development in order to relocate the powerlines and utility switchgear adjacent to Johns Creek.
Vehicular access to Southport West would be provided by Park Ave N, Lake Washington Blvd N, and the addition of an
internal center road and frontage road.
The site is generally level and consists of gravel yard and asphalt, a Puget Sound Energy switchgear, and an
office/warehouse building. The site contains high seismic hazard areas and the northeast corner of the site contains
Johns Creek and regulated slopes. The soil consists of a loose to medium dense sand, underlain by soft to medium dense
silt, then medium dense to dense sand, very soft silt and clay, and finally dense to very dense silty sand. Groundwater
was observed in the historical exploration at Southport at depths ranging from 3 to 10 feet below existing grade.
Preliminary estimates of cut and fill include approximately 25,000 cubic yards of excavation and 39,200 cubic yards of fill
from an approved source. The depth of excavation is anticipated to not exceed approximately two feet (2’) below ground
level, except for building cores where excavation would be deeper. Stormwater runoff from pollution generating surfaces
would be captured by catch basins and treated in cartridge filter facilities prior to connection into three (3) existing
drainage systems. No significant trees are proposed to be removed. Southport is proposing to plant 115 new trees along
with a variety of shrubs and perennials. The applicant has submitted a Preliminary Geotechnical Report, Technical
Information Report, Traffic Impact Analysis, and Stream Assessment and Final Mitigation Plan with the application.

Vehicular access to Southport West would be provided by Park Ave N, Lake Washington Blvd N, and the addition of an
internal center road and frontage road.
The site is generally level and consists of gravel yard and asphalt, a Puget Sound Energy switchgear, and an
office/warehouse building. The site contains high seismic hazard areas and the northeast corner of the site contains
Johns Creek and regulated slopes. The soil consists of a loose to medium dense sand, underlain by soft to medium dense
silt, then medium dense to dense sand, very soft silt and clay, and finally dense to very dense silty sand. Groundwater
was observed in the historical exploration at Southport at depths ranging from 3 to 10 feet below existing grade.
Preliminary estimates of cut and fill include approximately 25,000 cubic yards of excavation and 39,200 cubic yards of fill
from an approved source. The depth of excavation is anticipated to not exceed approximately two feet (2’) below ground
level, except for building cores where excavation would be deeper. Stormwater runoff from pollution generating surfaces
would be captured by catch basins and treated in cartridge filter facilities prior to connection into three (3) existing
drainage systems. No significant trees are proposed to be removed. Southport is proposing to plant 115 new trees along
with a variety of shrubs and perennials. The applicant has submitted a Preliminary Geotechnical Report, Technical
Information Report, Traffic Impact Analysis, and Stream Assessment and Final Mitigation Plan with the application.

PROJECT DESCRIPTION: The applicant, Southport West LLC, is requesting Master Plan Review, Hearing Examiner
Site Plan Review and Environmental (SEPA) Review for the construction of Southport West. Southport West is the
completion of the southerly portion of the Southport Development located at the south end of Lake Washington Blvd N.
The proposed expansion of Southport would be located on the 10.09-acre former Puget Sound Energy (PSE) Substation
and PSE utility parcels (APNs 082305-9191 and -9178). The two (2) parcels are located in the Urban Center-2 (UC-2) zone
and the Urban Design District ‘C’. The site is proposed to be developed as five (5) high-rise buildings with approximately
1,200,000 square feet of office and 50,000 of retail development in multiple phases. The proposed first three phases
would be developed as follows: Phase I – Towers 1 and 2 with the garage podium (July 2023 – July 2027), Phase II –
Towers 3 and 4 with garage podium (July 2027 – July 2031), and Phase III – Tower 5 (post July 2031). Phases 1-3 would
start on the south side of the site (closer to Boeing) and would develop to the north side of the lot (closer to Gene Coulon
Memorial Beach Park). A fourth and final phase is being considered for a sixth tower with 130,000 square feet for office
and retail at the south corner of the development near the intersection of Park Ave N and 757th Ave NE. The phased
development could reach as high as 1.6 million gross square feet. The proposed nine-level development would be built
at the same height and scale as the existing Southport offices with an overall height of approximately 154 feet above
average grade. Parking for 2,207 vehicles would be provided in a shared 4- and 5-level parking garage and 57 spaces are
proposed as on-street parking. In addition, the applicant is proposing to work closely with PSE for the engineering and

capacity needs of the development in order to relocate the powerlines and utility switchgear adjacent to Johns Creek.
Vehicular access to Southport West would be provided by Park Ave N, Lake Washington Blvd N, and the addition of an
internal center road and frontage road.
The site is generally level and consists of gravel yard and asphalt, a Puget Sound Energy switchgear, and an
office/warehouse building. The site contains high seismic hazard areas and the northeast corner of the site contains
Johns Creek and regulated slopes. The soil consists of a loose to medium dense sand, underlain by soft to medium dense
silt, then medium dense to dense sand, very soft silt and clay, and finally dense to very dense silty sand. Groundwater
was observed in the historical exploration at Southport at depths ranging from 3 to 10 feet below existing grade.
Preliminary estimates of cut and fill include approximately 25,000 cubic yards of excavation and 39,200 cubic yards of fill
from an approved source. The depth of excavation is anticipated to not exceed approximately two feet (2’) below ground
level, except for building cores where excavation would be deeper. Stormwater runoff from pollution generating surfaces
would be captured by catch basins and treated in cartridge filter facilities prior to connection into three (3) existing
drainage systems. No significant trees are proposed to be removed. Southport is proposing to plant 115 new trees along
with a variety of shrubs and perennials. The applicant has submitted a Preliminary Geotechnical Report, Technical
Information Report, Traffic Impact Analysis, and Stream Assessment and Final Mitigation Plan with the application.

PROJECT DESCRIPTION: The applicant, Southport West LLC, is requesting Master Plan Review, Hearing Examiner
Site Plan Review and Environmental (SEPA) Review for the construction of Southport West. Southport West is the
completion of the southerly portion of the Southport Development located at the south end of Lake Washington Blvd N.
The proposed expansion of Southport would be located on the 10.09-acre former Puget Sound Energy (PSE) Substation
and PSE utility parcels (APNs 082305-9191 and -9178). The two (2) parcels are located in the Urban Center-2 (UC-2) zone
and the Urban Design District ‘C’. The site is proposed to be developed as five (5) high-rise buildings with approximately
1,200,000 square feet of office and 50,000 of retail development in multiple phases. The proposed first three phases
would be developed as follows: Phase I – Towers 1 and 2 with the garage podium (July 2023 – July 2027), Phase II –
Towers 3 and 4 with garage podium (July 2027 – July 2031), and Phase III – Tower 5 (post July 2031). Phases 1-3 would
start on the south side of the site (closer to Boeing) and would develop to the north side of the lot (closer to Gene Coulon
Memorial Beach Park). A fourth and final phase is being considered for a sixth tower with 130,000 square feet for office
and retail at the south corner of the development near the intersection of Park Ave N and 757th Ave NE. The phased
development could reach as high as 1.6 million gross square feet. The proposed nine-level development would be built
at the same height and scale as the existing Southport offices with an overall height of approximately 154 feet above
average grade. Parking for 2,207 vehicles would be provided in a shared 4- and 5-level parking garage and 57 spaces are
proposed as on-street parking. In addition, the applicant is proposing to work closely with PSE for the engineering and

capacity needs of the development in order to relocate the powerlines and utility switchgear adjacent to Johns Creek.
Vehicular access to Southport West would be provided by Park Ave N, Lake Washington Blvd N, and the addition of an
internal center road and frontage road.
The site is generally level and consists of gravel yard and asphalt, a Puget Sound Energy switchgear, and an
office/warehouse building. The site contains high seismic hazard areas and the northeast corner of the site contains
Johns Creek and regulated slopes. The soil consists of a loose to medium dense sand, underlain by soft to medium dense
silt, then medium dense to dense sand, very soft silt and clay, and finally dense to very dense silty sand. Groundwater
was observed in the historical exploration at Southport at depths ranging from 3 to 10 feet below existing grade.
Preliminary estimates of cut and fill include approximately 25,000 cubic yards of excavation and 39,200 cubic yards of fill
from an approved source. The depth of excavation is anticipated to not exceed approximately two feet (2’) below ground
level, except for building cores where excavation would be deeper. Stormwater runoff from pollution generating surfaces
would be captured by catch basins and treated in cartridge filter facilities prior to connection into three (3) existing
drainage systems. No significant trees are proposed to be removed. Southport is proposing to plant 115 new trees along
with a variety of shrubs and perennials. The applicant has submitted a Preliminary Geotechnical Report, Technical
Information Report, Traffic Impact Analysis, and Stream Assessment and Final Mitigation Plan with the application.

PROJECT DESCRIPTION: The applicant, Southport West LLC, is requesting Master Plan Review, Hearing Examiner
Site Plan Review and Environmental (SEPA) Review for the construction of Southport West. Southport West is the
completion of the southerly portion of the Southport Development located at the south end of Lake Washington Blvd N.
The proposed expansion of Southport would be located on the 10.09-acre former Puget Sound Energy (PSE) Substation
and PSE utility parcels (APNs 082305-9191 and -9178). The two (2) parcels are located in the Urban Center-2 (UC-2) zone
and the Urban Design District ‘C’. The site is proposed to be developed as five (5) high-rise buildings with approximately
1,200,000 square feet of office and 50,000 of retail development in multiple phases. The proposed first three phases
would be developed as follows: Phase I – Towers 1 and 2 with the garage podium (July 2023 – July 2027), Phase II –
Towers 3 and 4 with garage podium (July 2027 – July 2031), and Phase III – Tower 5 (post July 2031). Phases 1-3 would
start on the south side of the site (closer to Boeing) and would develop to the north side of the lot (closer to Gene Coulon
Memorial Beach Park). A fourth and final phase is being considered for a sixth tower with 130,000 square feet for office
and retail at the south corner of the development near the intersection of Park Ave N and 757th Ave NE. The phased
development could reach as high as 1.6 million gross square feet. The proposed nine-level development would be built
at the same height and scale as the existing Southport offices with an overall height of approximately 154 feet above
average grade. Parking for 2,207 vehicles would be provided in a shared 4- and 5-level parking garage and 57 spaces are
proposed as on-street parking. In addition, the applicant is proposing to work closely with PSE for the engineering and

Vehicular access to Southport West would be provided by Park Ave N, Lake Washington Blvd N, and the addition of an
internal center road and frontage road.
The site is generally level and consists of gravel yard and asphalt, a Puget Sound Energy switchgear, and an
office/warehouse building. The site contains high seismic hazard areas and the northeast corner of the site contains
Johns Creek and regulated slopes. The soil consists of a loose to medium dense sand, underlain by soft to medium dense
silt, then medium dense to dense sand, very soft silt and clay, and finally dense to very dense silty sand. Groundwater
was observed in the historical exploration at Southport at depths ranging from 3 to 10 feet below existing grade.
Preliminary estimates of cut and fill include approximately 25,000 cubic yards of excavation and 39,200 cubic yards of fill
from an approved source. The depth of excavation is anticipated to not exceed approximately two feet (2’) below ground
level, except for building cores where excavation would be deeper. Stormwater runoff from pollution generating surfaces
would be captured by catch basins and treated in cartridge filter facilities prior to connection into three (3) existing

PROJECT DESCRIPTION: The applicant, Southport West LLC, is requesting Master Plan Review, Hearing Examiner
Site Plan Review and Environmental (SEPA) Review for the construction of Southport West. Southport West is the
completion of the southerly portion of the Southport Development located at the south end of Lake Washington Blvd N.
The proposed expansion of Southport would be located on the 10.09-acre former Puget Sound Energy (PSE) Substation
and PSE utility parcels (APNs 082305-9191 and -9178). The two (2) parcels are located in the Urban Center-2 (UC-2) zone
and the Urban Design District ‘C’. The site is proposed to be developed as five (5) high-rise buildings with approximately
1,200,000 square feet of office and 50,000 of retail development in multiple phases. The proposed first three phases
would be developed as follows: Phase I – Towers 1 and 2 with the garage podium (July 2023 – July 2027), Phase II –
Towers 3 and 4 with garage podium (July 2027 – July 2031), and Phase III – Tower 5 (post July 2031). Phases 1-3 would
start on the south side of the site (closer to Boeing) and would develop to the north side of the lot (closer to Gene Coulon
Memorial Beach Park). A fourth and final phase is being considered for a sixth tower with 130,000 square feet for office
and retail at the south corner of the development near the intersection of Park Ave N and 757th Ave NE. The phased
development could reach as high as 1.6 million gross square feet. The proposed nine-level development would be built
at the same height and scale as the existing Southport offices with an overall height of approximately 154 feet above
average grade. Parking for 2,207 vehicles would be provided in a shared 4- and 5-level parking garage and 57 spaces are
proposed as on-street parking. In addition, the applicant is proposing to work closely with PSE for the engineering and

capacity needs of the development in order to relocate the powerlines and utility switchgear adjacent to Johns Creek.
Vehicular access to Southport West would be provided by Park Ave N, Lake Washington Blvd N, and the addition of an
internal center road and frontage road.
The site is generally level and consists of gravel yard and asphalt, a Puget Sound Energy switchgear, and an
office/warehouse building. The site contains high seismic hazard areas and the northeast corner of the site contains
Johns Creek and regulated slopes. The soil consists of a loose to medium dense sand, underlain by soft to medium dense
silt, then medium dense to dense sand, very soft silt and clay, and finally dense to very dense silty sand. Groundwater
was observed in the historical exploration at Southport at depths ranging from 3 to 10 feet below existing grade.
Preliminary estimates of cut and fill include approximately 25,000 cubic yards of excavation and 39,200 cubic yards of fill
from an approved source. The depth of excavation is anticipated to not exceed approximately two feet (2’) below ground
level, except for building cores where excavation would be deeper. Stormwater runoff from pollution generating surfaces
would be captured by catch basins and treated in cartridge filter facilities prior to connection into three (3) existing
drainage systems. No significant trees are proposed to be removed. Southport is proposing to plant 115 new trees along
with a variety of shrubs and perennials. The applicant has submitted a Preliminary Geotechnical Report, Technical
Information Report, Traffic Impact Analysis, and Stream Assessment and Final Mitigation Plan with the application.

capacity needs of the development in order to relocate the powerlines and utility switchgear adjacent to Johns Creek.
Vehicular access to Southport West would be provided by Park Ave N, Lake Washington Blvd N, and the addition of an
internal center road and frontage road.
The site is generally level and consists of gravel yard and asphalt, a Puget Sound Energy switchgear, and an
office/warehouse building. The site contains high seismic hazard areas and the northeast corner of the site contains
Johns Creek and regulated slopes. The soil consists of a loose to medium dense sand, underlain by soft to medium dense
silt, then medium dense to dense sand, very soft silt and clay, and finally dense to very dense silty sand. Groundwater
was observed in the historical exploration at Southport at depths ranging from 3 to 10 feet below existing grade.
Preliminary estimates of cut and fill include approximately 25,000 cubic yards of excavation and 39,200 cubic yards of fill
from an approved source. The depth of excavation is anticipated to not exceed approximately two feet (2’) below ground
level, except for building cores where excavation would be deeper. Stormwater runoff from pollution generating surfaces
would be captured by catch basins and treated in cartridge filter facilities prior to connection into three (3) existing
drainage systems. No significant trees are proposed to be removed. Southport is proposing to plant 115 new trees along
with a variety of shrubs and perennials. The applicant has submitted a Preliminary Geotechnical Report, Technical
Information Report, Traffic Impact Analysis, and Stream Assessment and Final Mitigation Plan with the application.

PROJECT DESCRIPTION: The applicant, Southport West LLC, is requesting Master Plan Review, Hearing Examiner
Site Plan Review and Environmental (SEPA) Review for the construction of Southport West. Southport West is the
completion of the southerly portion of the Southport Development located at the south end of Lake Washington Blvd N.
The proposed expansion of Southport would be located on the 10.09-acre former Puget Sound Energy (PSE) Substation
and PSE utility parcels (APNs 082305-9191 and -9178). The two (2) parcels are located in the Urban Center-2 (UC-2) zone
and the Urban Design District ‘C’. The site is proposed to be developed as five (5) high-rise buildings with approximately
1,200,000 square feet of office and 50,000 of retail development in multiple phases. The proposed first three phases
would be developed as follows: Phase I – Towers 1 and 2 with the garage podium (July 2023 – July 2027), Phase II –
Towers 3 and 4 with garage podium (July 2027 – July 2031), and Phase III – Tower 5 (post July 2031). Phases 1-3 would
start on the south side of the site (closer to Boeing) and would develop to the north side of the lot (closer to Gene Coulon
Memorial Beach Park). A fourth and final phase is being considered for a sixth tower with 130,000 square feet for office
and retail at the south corner of the development near the intersection of Park Ave N and 757th Ave NE. The phased
development could reach as high as 1.6 million gross square feet. The proposed nine-level development would be built
at the same height and scale as the existing Southport offices with an overall height of approximately 154 feet above
average grade. Parking for 2,207 vehicles would be provided in a shared 4- and 5-level parking garage and 57 spaces are
proposed as on-street parking. In addition, the applicant is proposing to work closely with PSE for the engineering and

PROJECT DESCRIPTION: The applicant, Southport West LLC, is requesting Master Plan Review, Hearing Examiner
Site Plan Review and Environmental (SEPA) Review for the construction of Southport West. Southport West is the
completion of the southerly portion of the Southport Development located at the south end of Lake Washington Blvd N.
The proposed expansion of Southport would be located on the 10.09-acre former Puget Sound Energy (PSE) Substation
and PSE utility parcels (APNs 082305-9191 and -9178). The two (2) parcels are located in the Urban Center-2 (UC-2) zone
and the Urban Design District ‘C’. The site is proposed to be developed as five (5) high-rise buildings with approximately
1,200,000 square feet of office and 50,000 of retail development in multiple phases. The proposed first three phases
would be developed as follows: Phase I – Towers 1 and 2 with the garage podium (July 2023 – July 2027), Phase II –
Towers 3 and 4 with garage podium (July 2027 – July 2031), and Phase III – Tower 5 (post July 2031). Phases 1-3 would
start on the south side of the site (closer to Boeing) and would develop to the north side of the lot (closer to Gene Coulon
Memorial Beach Park). A fourth and final phase is being considered for a sixth tower with 130,000 square feet for office
and retail at the south corner of the development near the intersection of Park Ave N and 757th Ave NE. The phased
development could reach as high as 1.6 million gross square feet. The proposed nine-level development would be built
at the same height and scale as the existing Southport offices with an overall height of approximately 154 feet above
average grade. Parking for 2,207 vehicles would be provided in a shared 4- and 5-level parking garage and 57 spaces are
proposed as on-street parking. In addition, the applicant is proposing to work closely with PSE for the engineering and

capacity needs of the development in order to relocate the powerlines and utility switchgear adjacent to Johns Creek.
Vehicular access to Southport West would be provided by Park Ave N, Lake Washington Blvd N, and the addition of an
internal center road and frontage road.
The site is generally level and consists of gravel yard and asphalt, a Puget Sound Energy switchgear, and an
office/warehouse building. The site contains high seismic hazard areas and the northeast corner of the site contains
Johns Creek and regulated slopes. The soil consists of a loose to medium dense sand, underlain by soft to medium dense
silt, then medium dense to dense sand, very soft silt and clay, and finally dense to very dense silty sand. Groundwater
was observed in the historical exploration at Southport at depths ranging from 3 to 10 feet below existing grade.
Preliminary estimates of cut and fill include approximately 25,000 cubic yards of excavation and 39,200 cubic yards of fill
from an approved source. The depth of excavation is anticipated to not exceed approximately two feet (2’) below ground
level, except for building cores where excavation would be deeper. Stormwater runoff from pollution generating surfaces
would be captured by catch basins and treated in cartridge filter facilities prior to connection into three (3) existing
drainage systems. No significant trees are proposed to be removed. Southport is proposing to plant 115 new trees along
with a variety of shrubs and perennials. The applicant has submitted a Preliminary Geotechnical Report, Technical
Information Report, Traffic Impact Analysis, and Stream Assessment and Final Mitigation Plan with the application.

Towers 3 and 4 with garage podium (July 2027 – July 2031), and Phase III – Tower 5 (post July 2031). Phases 1-3 would
start on the south side of the site (closer to Boeing) and would develop to the north side of the lot (closer to Gene Coulon
Memorial Beach Park). A fourth and final phase is being considered for a sixth tower with 130,000 square feet for office
and retail at the south corner of the development near the intersection of Park Ave N and 757th Ave NE. The phased
development could reach as high as 1.6 million gross square feet. The proposed nine-level development would be built
at the same height and scale as the existing Southport offices with an overall height of approximately 154 feet above
average grade. Parking for 2,207 vehicles would be provided in a shared 4- and 5-level parking garage and 57 spaces are
proposed as on-street parking. In addition, the applicant is proposing to work closely with PSE for the engineering and

Vehicular access to Southport West would be provided by Park Ave N, Lake Washington Blvd N, and the addition of an
internal center road and frontage road.
The site is generally level and consists of gravel yard and asphalt, a Puget Sound Energy switchgear, and an
office/warehouse building. The site contains high seismic hazard areas and the northeast corner of the site contains
Johns Creek and regulated slopes. The soil consists of a loose to medium dense sand, underlain by soft to medium dense
silt, then medium dense to dense sand, very soft silt and clay, and finally dense to very dense silty sand. Groundwater
was observed in the historical exploration at Southport at depths ranging from 3 to 10 feet below existing grade.
Preliminary estimates of cut and fill include approximately 25,000 cubic yards of excavation and 39,200 cubic yards of fill
from an approved source. The depth of excavation is anticipated to not exceed approximately two feet (2’) below ground
level, except for building cores where excavation would be deeper. Stormwater runoff from pollution generating surfaces
would be captured by catch basins and treated in cartridge filter facilities prior to connection into three (3) existing
drainage systems. No significant trees are proposed to be removed. Southport is proposing to plant 115 new trees along
with a variety of shrubs and perennials. The applicant has submitted a Preliminary Geotechnical Report, Technical
Information Report, Traffic Impact Analysis, and Stream Assessment and Final Mitigation Plan with the application.

PROJECT DESCRIPTION: The applicant, Southport West LLC, is requesting Master Plan Review, Hearing Examiner
Site Plan Review and Environmental (SEPA) Review for the construction of Southport West. Southport West is the
completion of the southerly portion of the Southport Development located at the south end of Lake Washington Blvd N.
The proposed expansion of Southport would be located on the 10.09-acre former Puget Sound Energy (PSE) Substation
and PSE utility parcels (APNs 082305-9191 and -9178). The two (2) parcels are located in the Urban Center-2 (UC-2) zone
and the Urban Design District ‘C’. The site is proposed to be developed as five (5) high-rise buildings with approximately
1,200,000 square feet of office and 50,000 of retail development in multiple phases. The proposed first three phases
would be developed as follows: Phase I – Towers 1 and 2 with the garage podium (July 2023 – July 2027), Phase II –
Towers 3 and 4 with garage podium (July 2027 – July 2031), and Phase III – Tower 5 (post July 2031). Phases 1-3 would
start on the south side of the site (closer to Boeing) and would develop to the north side of the lot (closer to Gene Coulon
Memorial Beach Park). A fourth and final phase is being considered for a sixth tower with 130,000 square feet for office
and retail at the south corner of the development near the intersection of Park Ave N and 757th Ave NE. The phased
development could reach as high as 1.6 million gross square feet. The proposed nine-level development would be built
at the same height and scale as the existing Southport offices with an overall height of approximately 154 feet above
average grade. Parking for 2,207 vehicles would be provided in a shared 4- and 5-level parking garage and 57 spaces are
proposed as on-street parking. In addition, the applicant is proposing to work closely with PSE for the engineering and

capacity needs of the development in order to relocate the powerlines and utility switchgear adjacent to Johns Creek.
Vehicular access to Southport West would be provided by Park Ave N, Lake Washington Blvd N, and the addition of an
internal center road and frontage road.
The site is generally level and consists of gravel yard and asphalt, a Puget Sound Energy switchgear, and an
office/warehouse building. The site contains high seismic hazard areas and the northeast corner of the site contains
Johns Creek and regulated slopes. The soil consists of a loose to medium dense sand, underlain by soft to medium dense
silt, then medium dense to dense sand, very soft silt and clay, and finally dense to very dense silty sand. Groundwater
was observed in the historical exploration at Southport at depths ranging from 3 to 10 feet below existing grade.
Preliminary estimates of cut and fill include approximately 25,000 cubic yards of excavation and 39,200 cubic yards of fill
from an approved source. The depth of excavation is anticipated to not exceed approximately two feet (2’) below ground
level, except for building cores where excavation would be deeper. Stormwater runoff from pollution generating surfaces
would be captured by catch basins and treated in cartridge filter facilities prior to connection into three (3) existing
drainage systems. No significant trees are proposed to be removed. Southport is proposing to plant 115 new trees along
with a variety of shrubs and perennials. The applicant has submitted a Preliminary Geotechnical Report, Technical
Information Report, Traffic Impact Analysis, and Stream Assessment and Final Mitigation Plan with the application.

PROJECT DESCRIPTION: The applicant, Southport West LLC, is requesting Master Plan Review, Hearing Examiner
Site Plan Review and Environmental (SEPA) Review for the construction of Southport West. Southport West is the
completion of the southerly portion of the Southport Development located at the south end of Lake Washington Blvd N.
The proposed expansion of Southport would be located on the 10.09-acre former Puget Sound Energy (PSE) Substation
and PSE utility parcels (APNs 082305-9191 and -9178). The two (2) parcels are located in the Urban Center-2 (UC-2) zone
and the Urban Design District ‘C’. The site is proposed to be developed as five (5) high-rise buildings with approximately
1,200,000 square feet of office and 50,000 of retail development in multiple phases. The proposed first three phases
would be developed as follows: Phase I – Towers 1 and 2 with the garage podium (July 2023 – July 2027), Phase II –
Towers 3 and 4 with garage podium (July 2027 – July 2031), and Phase III – Tower 5 (post July 2031). Phases 1-3 would
start on the south side of the site (closer to Boeing) and would develop to the north side of the lot (closer to Gene Coulon
Memorial Beach Park). A fourth and final phase is being considered for a sixth tower with 130,000 square feet for office
and retail at the south corner of the development near the intersection of Park Ave N and 757th Ave NE. The phased
development could reach as high as 1.6 million gross square feet. The proposed nine-level development would be built
at the same height and scale as the existing Southport offices with an overall height of approximately 154 feet above
average grade. Parking for 2,207 vehicles would be provided in a shared 4- and 5-level parking garage and 57 spaces are
proposed as on-street parking. In addition, the applicant is proposing to work closely with PSE for the engineering and

capacity needs of the development in order to relocate the powerlines and utility switchgear adjacent to Johns Creek.
Vehicular access to Southport West would be provided by Park Ave N, Lake Washington Blvd N, and the addition of an
internal center road and frontage road.
The site is generally level and consists of gravel yard and asphalt, a Puget Sound Energy switchgear, and an
office/warehouse building. The site contains high seismic hazard areas and the northeast corner of the site contains
Johns Creek and regulated slopes. The soil consists of a loose to medium dense sand, underlain by soft to medium dense
silt, then medium dense to dense sand, very soft silt and clay, and finally dense to very dense silty sand. Groundwater
was observed in the historical exploration at Southport at depths ranging from 3 to 10 feet below existing grade.
Preliminary estimates of cut and fill include approximately 25,000 cubic yards of excavation and 39,200 cubic yards of fill
from an approved source. The depth of excavation is anticipated to not exceed approximately two feet (2’) below ground
level, except for building cores where excavation would be deeper. Stormwater runoff from pollution generating surfaces
would be captured by catch basins and treated in cartridge filter facilities prior to connection into three (3) existing
drainage systems. No significant trees are proposed to be removed. Southport is proposing to plant 115 new trees along
with a variety of shrubs and perennials. The applicant has submitted a Preliminary Geotechnical Report, Technical
Information Report, Traffic Impact Analysis, and Stream Assessment and Final Mitigation Plan with the application.

office/warehouse building. The site contains high seismic hazard areas and the northeast corner of the site contains
Johns Creek and regulated slopes. The soil consists of a loose to medium dense sand, underlain by soft to medium dense
silt, then medium dense to dense sand, very soft silt and clay, and finally dense to very dense silty sand. Groundwater
was observed in the historical exploration at Southport at depths ranging from 3 to 10 feet below existing grade.
Preliminary estimates of cut and fill include approximately 25,000 cubic yards of excavation and 39,200 cubic yards of fill
from an approved source. The depth of excavation is anticipated to not exceed approximately two feet (2’) below ground
level, except for building cores where excavation would be deeper. Stormwater runoff from pollution generating surfaces
would be captured by catch basins and treated in cartridge filter facilities prior to connection into three (3) existing
drainage systems. No significant trees are proposed to be removed. Southport is proposing to plant 115 new trees along
with a variety of shrubs and perennials. The applicant has submitted a Preliminary Geotechnical Report, Technical
Information Report, Traffic Impact Analysis, and Stream Assessment and Final Mitigation Plan with the application.

Site Plan Review and Environmental (SEPA) Review for the construction of Southport West. Southport West is the
completion of the southerly portion of the Southport Development located at the south end of Lake Washington Blvd N.
The proposed expansion of Southport would be located on the 10.09-acre former Puget Sound Energy (PSE) Substation
and PSE utility parcels (APNs 082305-9191 and -9178). The two (2) parcels are located in the Urban Center-2 (UC-2) zone
and the Urban Design District ‘C’. The site is proposed to be developed as five (5) high-rise buildings with approximately
1,200,000 square feet of office and 50,000 of retail development in multiple phases. The proposed first three phases
would be developed as follows: Phase I – Towers 1 and 2 with the garage podium (July 2023 – July 2027), Phase II –
Towers 3 and 4 with garage podium (July 2027 – July 2031), and Phase III – Tower 5 (post July 2031). Phases 1-3 would
start on the south side of the site (closer to Boeing) and would develop to the north side of the lot (closer to Gene Coulon
Memorial Beach Park). A fourth and final phase is being considered for a sixth tower with 130,000 square feet for office
and retail at the south corner of the development near the intersection of Park Ave N and 757th Ave NE. The phased
development could reach as high as 1.6 million gross square feet. The proposed nine-level development would be built
at the same height and scale as the existing Southport offices with an overall height of approximately 154 feet above
average grade. Parking for 2,207 vehicles would be provided in a shared 4- and 5-level parking garage and 57 spaces are
proposed as on-street parking. In addition, the applicant is proposing to work closely with PSE for the engineering and

PROJECT DESCRIPTION: The applicant, Southport West LLC, is requesting Master Plan Review, Hearing Examiner
Site Plan Review and Environmental (SEPA) Review for the construction of Southport West. Southport West is the
completion of the southerly portion of the Southport Development located at the south end of Lake Washington Blvd N.
The proposed expansion of Southport would be located on the 10.09-acre former Puget Sound Energy (PSE) Substation
and PSE utility parcels (APNs 082305-9191 and -9178). The two (2) parcels are located in the Urban Center-2 (UC-2) zone
and the Urban Design District ‘C’. The site is proposed to be developed as five (5) high-rise buildings with approximately
1,200,000 square feet of office and 50,000 of retail development in multiple phases. The proposed first three phases
would be developed as follows: Phase I – Towers 1 and 2 with the garage podium (July 2023 – July 2027), Phase II –
Towers 3 and 4 with garage podium (July 2027 – July 2031), and Phase III – Tower 5 (post July 2031). Phases 1-3 would
start on the south side of the site (closer to Boeing) and would develop to the north side of the lot (closer to Gene Coulon
Memorial Beach Park). A fourth and final phase is being considered for a sixth tower with 130,000 square feet for office
and retail at the south corner of the development near the intersection of Park Ave N and 757th Ave NE. The phased
development could reach as high as 1.6 million gross square feet. The proposed nine-level development would be built
at the same height and scale as the existing Southport offices with an overall height of approximately 154 feet above
average grade. Parking for 2,207 vehicles would be provided in a shared 4- and 5-level parking garage and 57 spaces are
proposed as on-street parking. In addition, the applicant is proposing to work closely with PSE for the engineering and

capacity needs of the development in order to relocate the powerlines and utility switchgear adjacent to Johns Creek.
Vehicular access to Southport West would be provided by Park Ave N, Lake Washington Blvd N, and the addition of an
internal center road and frontage road.
The site is generally level and consists of gravel yard and asphalt, a Puget Sound Energy switchgear, and an
office/warehouse building. The site contains high seismic hazard areas and the northeast corner of the site contains
Johns Creek and regulated slopes. The soil consists of a loose to medium dense sand, underlain by soft to medium dense
silt, then medium dense to dense sand, very soft silt and clay, and finally dense to very dense silty sand. Groundwater
was observed in the historical exploration at Southport at depths ranging from 3 to 10 feet below existing grade.
Preliminary estimates of cut and fill include approximately 25,000 cubic yards of excavation and 39,200 cubic yards of fill
from an approved source. The depth of excavation is anticipated to not exceed approximately two feet (2’) below ground
level, except for building cores where excavation would be deeper. Stormwater runoff from pollution generating surfaces
would be captured by catch basins and treated in cartridge filter facilities prior to connection into three (3) existing
drainage systems. No significant trees are proposed to be removed. Southport is proposing to plant 115 new trees along
with a variety of shrubs and perennials. The applicant has submitted a Preliminary Geotechnical Report, Technical
Information Report, Traffic Impact Analysis, and Stream Assessment and Final Mitigation Plan with the application.

capacity needs of the development in order to relocate the powerlines and utility switchgear adjacent to Johns Creek.
Vehicular access to Southport West would be provided by Park Ave N, Lake Washington Blvd N, and the addition of an
internal center road and frontage road.
The site is generally level and consists of gravel yard and asphalt, a Puget Sound Energy switchgear, and an
office/warehouse building. The site contains high seismic hazard areas and the northeast corner of the site contains
Johns Creek and regulated slopes. The soil consists of a loose to medium dense sand, underlain by soft to medium dense
silt, then medium dense to dense sand, very soft silt and clay, and finally dense to very dense silty sand. Groundwater
was observed in the historical exploration at Southport at depths ranging from 3 to 10 feet below existing grade.
Preliminary estimates of cut and fill include approximately 25,000 cubic yards of excavation and 39,200 cubic yards of fill
from an approved source. The depth of excavation is anticipated to not exceed approximately two feet (2’) below ground
level, except for building cores where excavation would be deeper. Stormwater runoff from pollution generating surfaces
would be captured by catch basins and treated in cartridge filter facilities prior to connection into three (3) existing
drainage systems. No significant trees are proposed to be removed. Southport is proposing to plant 115 new trees along
with a variety of shrubs and perennials. The applicant has submitted a Preliminary Geotechnical Report, Technical
Information Report, Traffic Impact Analysis, and Stream Assessment and Final Mitigation Plan with the application.

The proposed expansion of Southport would be located on the 10.09-acre former Puget Sound Energy (PSE) Substation
and PSE utility parcels (APNs 082305-9191 and -9178). The two (2) parcels are located in the Urban Center-2 (UC-2) zone
and the Urban Design District ‘C’. The site is proposed to be developed as five (5) high-rise buildings with approximately
1,200,000 square feet of office and 50,000 of retail development in multiple phases. The proposed first three phases
would be developed as follows: Phase I – Towers 1 and 2 with the garage podium (July 2023 – July 2027), Phase II –
Towers 3 and 4 with garage podium (July 2027 – July 2031), and Phase III – Tower 5 (post July 2031). Phases 1-3 would
start on the south side of the site (closer to Boeing) and would develop to the north side of the lot (closer to Gene Coulon
Memorial Beach Park). A fourth and final phase is being considered for a sixth tower with 130,000 square feet for office
and retail at the south corner of the development near the intersection of Park Ave N and 757th Ave NE. The phased
development could reach as high as 1.6 million gross square feet. The proposed nine-level development would be built
at the same height and scale as the existing Southport offices with an overall height of approximately 154 feet above
average grade. Parking for 2,207 vehicles would be provided in a shared 4- and 5-level parking garage and 57 spaces are

PROJECT DESCRIPTION: The applicant, Southport West LLC, is requesting Master Plan Review, Hearing Examiner
Site Plan Review and Environmental (SEPA) Review for the construction of Southport West. Southport West is the
completion of the southerly portion of the Southport Development located at the south end of Lake Washington Blvd N.
The proposed expansion of Southport would be located on the 10.09-acre former Puget Sound Energy (PSE) Substation
and PSE utility parcels (APNs 082305-9191 and -9178). The two (2) parcels are located in the Urban Center-2 (UC-2) zone
and the Urban Design District ‘C’. The site is proposed to be developed as five (5) high-rise buildings with approximately
1,200,000 square feet of office and 50,000 of retail development in multiple phases. The proposed first three phases
would be developed as follows: Phase I – Towers 1 and 2 with the garage podium (July 2023 – July 2027), Phase II –
Towers 3 and 4 with garage podium (July 2027 – July 2031), and Phase III – Tower 5 (post July 2031). Phases 1-3 would
start on the south side of the site (closer to Boeing) and would develop to the north side of the lot (closer to Gene Coulon
Memorial Beach Park). A fourth and final phase is being considered for a sixth tower with 130,000 square feet for office
and retail at the south corner of the development near the intersection of Park Ave N and 757th Ave NE. The phased
development could reach as high as 1.6 million gross square feet. The proposed nine-level development would be built
at the same height and scale as the existing Southport offices with an overall height of approximately 154 feet above
average grade. Parking for 2,207 vehicles would be provided in a shared 4- and 5-level parking garage and 57 spaces are
proposed as on-street parking. In addition, the applicant is proposing to work closely with PSE for the engineering and

capacity needs of the development in order to relocate the powerlines and utility switchgear adjacent to Johns Creek.
Vehicular access to Southport West would be provided by Park Ave N, Lake Washington Blvd N, and the addition of an
internal center road and frontage road.
The site is generally level and consists of gravel yard and asphalt, a Puget Sound Energy switchgear, and an
office/warehouse building. The site contains high seismic hazard areas and the northeast corner of the site contains
Johns Creek and regulated slopes. The soil consists of a loose to medium dense sand, underlain by soft to medium dense
silt, then medium dense to dense sand, very soft silt and clay, and finally dense to very dense silty sand. Groundwater
was observed in the historical exploration at Southport at depths ranging from 3 to 10 feet below existing grade.
Preliminary estimates of cut and fill include approximately 25,000 cubic yards of excavation and 39,200 cubic yards of fill
from an approved source. The depth of excavation is anticipated to not exceed approximately two feet (2’) below ground
level, except for building cores where excavation would be deeper. Stormwater runoff from pollution generating surfaces
would be captured by catch basins and treated in cartridge filter facilities prior to connection into three (3) existing
drainage systems. No significant trees are proposed to be removed. Southport is proposing to plant 115 new trees along
with a variety of shrubs and perennials. The applicant has submitted a Preliminary Geotechnical Report, Technical
Information Report, Traffic Impact Analysis, and Stream Assessment and Final Mitigation Plan with the application.

and PSE utility parcels (APNs 082305-9191 and -9178). The two (2) parcels are located in the Urban Center-2 (UC-2) zone
and the Urban Design District ‘C’. The site is proposed to be developed as five (5) high-rise buildings with approximately
1,200,000 square feet of office and 50,000 of retail development in multiple phases. The proposed first three phases
would be developed as follows: Phase I – Towers 1 and 2 with the garage podium (July 2023 – July 2027), Phase II –
Towers 3 and 4 with garage podium (July 2027 – July 2031), and Phase III – Tower 5 (post July 2031). Phases 1-3 would
start on the south side of the site (closer to Boeing) and would develop to the north side of the lot (closer to Gene Coulon
Memorial Beach Park). A fourth and final phase is being considered for a sixth tower with 130,000 square feet for office
and retail at the south corner of the development near the intersection of Park Ave N and 757th Ave NE. The phased
development could reach as high as 1.6 million gross square feet. The proposed nine-level development would be built
at the same height and scale as the existing Southport offices with an overall height of approximately 154 feet above
average grade. Parking for 2,207 vehicles would be provided in a shared 4- and 5-level parking garage and 57 spaces are
proposed as on-street parking. In addition, the applicant is proposing to work closely with PSE for the engineering and

capacity needs of the development in order to relocate the powerlines and utility switchgear adjacent to Johns Creek.
Vehicular access to Southport West would be provided by Park Ave N, Lake Washington Blvd N, and the addition of an
internal center road and frontage road.
The site is generally level and consists of gravel yard and asphalt, a Puget Sound Energy switchgear, and an
office/warehouse building. The site contains high seismic hazard areas and the northeast corner of the site contains
Johns Creek and regulated slopes. The soil consists of a loose to medium dense sand, underlain by soft to medium dense
silt, then medium dense to dense sand, very soft silt and clay, and finally dense to very dense silty sand. Groundwater
was observed in the historical exploration at Southport at depths ranging from 3 to 10 feet below existing grade.
Preliminary estimates of cut and fill include approximately 25,000 cubic yards of excavation and 39,200 cubic yards of fill
from an approved source. The depth of excavation is anticipated to not exceed approximately two feet (2’) below ground
level, except for building cores where excavation would be deeper. Stormwater runoff from pollution generating surfaces
would be captured by catch basins and treated in cartridge filter facilities prior to connection into three (3) existing
drainage systems. No significant trees are proposed to be removed. Southport is proposing to plant 115 new trees along
with a variety of shrubs and perennials. The applicant has submitted a Preliminary Geotechnical Report, Technical
Information Report, Traffic Impact Analysis, and Stream Assessment and Final Mitigation Plan with the application.

PROJECT DESCRIPTION: The applicant, Southport West LLC, is requesting Master Plan Review, Hearing Examiner
Site Plan Review and Environmental (SEPA) Review for the construction of Southport West. Southport West is the
completion of the southerly portion of the Southport Development located at the south end of Lake Washington Blvd N.
The proposed expansion of Southport would be located on the 10.09-acre former Puget Sound Energy (PSE) Substation
and PSE utility parcels (APNs 082305-9191 and -9178). The two (2) parcels are located in the Urban Center-2 (UC-2) zone
and the Urban Design District ‘C’. The site is proposed to be developed as five (5) high-rise buildings with approximately
1,200,000 square feet of office and 50,000 of retail development in multiple phases. The proposed first three phases
would be developed as follows: Phase I – Towers 1 and 2 with the garage podium (July 2023 – July 2027), Phase II –
Towers 3 and 4 with garage podium (July 2027 – July 2031), and Phase III – Tower 5 (post July 2031). Phases 1-3 would
start on the south side of the site (closer to Boeing) and would develop to the north side of the lot (closer to Gene Coulon
Memorial Beach Park). A fourth and final phase is being considered for a sixth tower with 130,000 square feet for office
and retail at the south corner of the development near the intersection of Park Ave N and 757th Ave NE. The phased
development could reach as high as 1.6 million gross square feet. The proposed nine-level development would be built
at the same height and scale as the existing Southport offices with an overall height of approximately 154 feet above
average grade. Parking for 2,207 vehicles would be provided in a shared 4- and 5-level parking garage and 57 spaces are
proposed as on-street parking. In addition, the applicant is proposing to work closely with PSE for the engineering and

Vehicular access to Southport West would be provided by Park Ave N, Lake Washington Blvd N, and the addition of an
internal center road and frontage road.
The site is generally level and consists of gravel yard and asphalt, a Puget Sound Energy switchgear, and an
office/warehouse building. The site contains high seismic hazard areas and the northeast corner of the site contains
Johns Creek and regulated slopes. The soil consists of a loose to medium dense sand, underlain by soft to medium dense
silt, then medium dense to dense sand, very soft silt and clay, and finally dense to very dense silty sand. Groundwater
was observed in the historical exploration at Southport at depths ranging from 3 to 10 feet below existing grade.
Preliminary estimates of cut and fill include approximately 25,000 cubic yards of excavation and 39,200 cubic yards of fill
from an approved source. The depth of excavation is anticipated to not exceed approximately two feet (2’) below ground
level, except for building cores where excavation would be deeper. Stormwater runoff from pollution generating surfaces
would be captured by catch basins and treated in cartridge filter facilities prior to connection into three (3) existing
drainage systems. No significant trees are proposed to be removed. Southport is proposing to plant 115 new trees along
with a variety of shrubs and perennials. The applicant has submitted a Preliminary Geotechnical Report, Technical
Information Report, Traffic Impact Analysis, and Stream Assessment and Final Mitigation Plan with the application.

PROJECT DESCRIPTION: The applicant, Southport West LLC, is requesting Master Plan Review, Hearing Examiner
Site Plan Review and Environmental (SEPA) Review for the construction of Southport West. Southport West is the
completion of the southerly portion of the Southport Development located at the south end of Lake Washington Blvd N.
The proposed expansion of Southport would be located on the 10.09-acre former Puget Sound Energy (PSE) Substation
and PSE utility parcels (APNs 082305-9191 and -9178). The two (2) parcels are located in the Urban Center-2 (UC-2) zone
and the Urban Design District ‘C’. The site is proposed to be developed as five (5) high-rise buildings with approximately
1,200,000 square feet of office and 50,000 of retail development in multiple phases. The proposed first three phases
would be developed as follows: Phase I – Towers 1 and 2 with the garage podium (July 2023 – July 2027), Phase II –
Towers 3 and 4 with garage podium (July 2027 – July 2031), and Phase III – Tower 5 (post July 2031). Phases 1-3 would
start on the south side of the site (closer to Boeing) and would develop to the north side of the lot (closer to Gene Coulon
Memorial Beach Park). A fourth and final phase is being considered for a sixth tower with 130,000 square feet for office
and retail at the south corner of the development near the intersection of Park Ave N and 757th Ave NE. The phased
development could reach as high as 1.6 million gross square feet. The proposed nine-level development would be built
at the same height and scale as the existing Southport offices with an overall height of approximately 154 feet above
average grade. Parking for 2,207 vehicles would be provided in a shared 4- and 5-level parking garage and 57 spaces are
proposed as on-street parking. In addition, the applicant is proposing to work closely with PSE for the engineering and

capacity needs of the development in order to relocate the powerlines and utility switchgear adjacent to Johns Creek.
Vehicular access to Southport West would be provided by Park Ave N, Lake Washington Blvd N, and the addition of an
internal center road and frontage road.
The site is generally level and consists of gravel yard and asphalt, a Puget Sound Energy switchgear, and an
office/warehouse building. The site contains high seismic hazard areas and the northeast corner of the site contains
Johns Creek and regulated slopes. The soil consists of a loose to medium dense sand, underlain by soft to medium dense
silt, then medium dense to dense sand, very soft silt and clay, and finally dense to very dense silty sand. Groundwater
was observed in the historical exploration at Southport at depths ranging from 3 to 10 feet below existing grade.
Preliminary estimates of cut and fill include approximately 25,000 cubic yards of excavation and 39,200 cubic yards of fill
from an approved source. The depth of excavation is anticipated to not exceed approximately two feet (2’) below ground
level, except for building cores where excavation would be deeper. Stormwater runoff from pollution generating surfaces
would be captured by catch basins and treated in cartridge filter facilities prior to connection into three (3) existing
drainage systems. No significant trees are proposed to be removed. Southport is proposing to plant 115 new trees along
with a variety of shrubs and perennials. The applicant has submitted a Preliminary Geotechnical Report, Technical
Information Report, Traffic Impact Analysis, and Stream Assessment and Final Mitigation Plan with the application.

capacity needs of the development in order to relocate the powerlines and utility switchgear adjacent to Johns Creek.
Vehicular access to Southport West would be provided by Park Ave N, Lake Washington Blvd N, and the addition of an
internal center road and frontage road.
The site is generally level and consists of gravel yard and asphalt, a Puget Sound Energy switchgear, and an
office/warehouse building. The site contains high seismic hazard areas and the northeast corner of the site contains
Johns Creek and regulated slopes. The soil consists of a loose to medium dense sand, underlain by soft to medium dense
silt, then medium dense to dense sand, very soft silt and clay, and finally dense to very dense silty sand. Groundwater
was observed in the historical exploration at Southport at depths ranging from 3 to 10 feet below existing grade.
Preliminary estimates of cut and fill include approximately 25,000 cubic yards of excavation and 39,200 cubic yards of fill
from an approved source. The depth of excavation is anticipated to not exceed approximately two feet (2’) below ground
level, except for building cores where excavation would be deeper. Stormwater runoff from pollution generating surfaces
would be captured by catch basins and treated in cartridge filter facilities prior to connection into three (3) existing
drainage systems. No significant trees are proposed to be removed. Southport is proposing to plant 115 new trees along
with a variety of shrubs and perennials. The applicant has submitted a Preliminary Geotechnical Report, Technical
Information Report, Traffic Impact Analysis, and Stream Assessment and Final Mitigation Plan with the application.

Site Plan Review and Environmental (SEPA) Review for the construction of Southport West. Southport West is the
completion of the southerly portion of the Southport Development located at the south end of Lake Washington Blvd N.
The proposed expansion of Southport would be located on the 10.09-acre former Puget Sound Energy (PSE) Substation
and PSE utility parcels (APNs 082305-9191 and -9178). The two (2) parcels are located in the Urban Center-2 (UC-2) zone
and the Urban Design District ‘C’. The site is proposed to be developed as five (5) high-rise buildings with approximately
1,200,000 square feet of office and 50,000 of retail development in multiple phases. The proposed first three phases
would be developed as follows: Phase I – Towers 1 and 2 with the garage podium (July 2023 – July 2027), Phase II –
Towers 3 and 4 with garage podium (July 2027 – July 2031), and Phase III – Tower 5 (post July 2031). Phases 1-3 would
start on the south side of the site (closer to Boeing) and would develop to the north side of the lot (closer to Gene Coulon
Memorial Beach Park). A fourth and final phase is being considered for a sixth tower with 130,000 square feet for office
and retail at the south corner of the development near the intersection of Park Ave N and 757th Ave NE. The phased
development could reach as high as 1.6 million gross square feet. The proposed nine-level development would be built
at the same height and scale as the existing Southport offices with an overall height of approximately 154 feet above
average grade. Parking for 2,207 vehicles would be provided in a shared 4- and 5-level parking garage and 57 spaces are
proposed as on-street parking. In addition, the applicant is proposing to work closely with PSE for the engineering and

PROJECT DESCRIPTION: The applicant, Southport West LLC, is requesting Master Plan Review, Hearing Examiner
Site Plan Review and Environmental (SEPA) Review for the construction of Southport West. Southport West is the
completion of the southerly portion of the Southport Development located at the south end of Lake Washington Blvd N.
The proposed expansion of Southport would be located on the 10.09-acre former Puget Sound Energy (PSE) Substation
and PSE utility parcels (APNs 082305-9191 and -9178). The two (2) parcels are located in the Urban Center-2 (UC-2) zone
and the Urban Design District ‘C’. The site is proposed to be developed as five (5) high-rise buildings with approximately
1,200,000 square feet of office and 50,000 of retail development in multiple phases. The proposed first three phases
would be developed as follows: Phase I – Towers 1 and 2 with the garage podium (July 2023 – July 2027), Phase II –
Towers 3 and 4 with garage podium (July 2027 – July 2031), and Phase III – Tower 5 (post July 2031). Phases 1-3 would
start on the south side of the site (closer to Boeing) and would develop to the north side of the lot (closer to Gene Coulon
Memorial Beach Park). A fourth and final phase is being considered for a sixth tower with 130,000 square feet for office
and retail at the south corner of the development near the intersection of Park Ave N and 757th Ave NE. The phased
development could reach as high as 1.6 million gross square feet. The proposed nine-level development would be built
at the same height and scale as the existing Southport offices with an overall height of approximately 154 feet above
average grade. Parking for 2,207 vehicles would be provided in a shared 4- and 5-level parking garage and 57 spaces are
proposed as on-street parking. In addition, the applicant is proposing to work closely with PSE for the engineering and

capacity needs of the development in order to relocate the powerlines and utility switchgear adjacent to Johns Creek.
Vehicular access to Southport West would be provided by Park Ave N, Lake Washington Blvd N, and the addition of an
internal center road and frontage road.
The site is generally level and consists of gravel yard and asphalt, a Puget Sound Energy switchgear, and an
office/warehouse building. The site contains high seismic hazard areas and the northeast corner of the site contains
Johns Creek and regulated slopes. The soil consists of a loose to medium dense sand, underlain by soft to medium dense
silt, then medium dense to dense sand, very soft silt and clay, and finally dense to very dense silty sand. Groundwater
was observed in the historical exploration at Southport at depths ranging from 3 to 10 feet below existing grade.
Preliminary estimates of cut and fill include approximately 25,000 cubic yards of excavation and 39,200 cubic yards of fill
from an approved source. The depth of excavation is anticipated to not exceed approximately two feet (2’) below ground
level, except for building cores where excavation would be deeper. Stormwater runoff from pollution generating surfaces
would be captured by catch basins and treated in cartridge filter facilities prior to connection into three (3) existing
drainage systems. No significant trees are proposed to be removed. Southport is proposing to plant 115 new trees along
with a variety of shrubs and perennials. The applicant has submitted a Preliminary Geotechnical Report, Technical
Information Report, Traffic Impact Analysis, and Stream Assessment and Final Mitigation Plan with the application.

Vehicular access to Southport West would be provided by Park Ave N, Lake Washington Blvd N, and the addition of an
internal center road and frontage road.
The site is generally level and consists of gravel yard and asphalt, a Puget Sound Energy switchgear, and an
office/warehouse building. The site contains high seismic hazard areas and the northeast corner of the site contains
Johns Creek and regulated slopes. The soil consists of a loose to medium dense sand, underlain by soft to medium dense
silt, then medium dense to dense sand, very soft silt and clay, and finally dense to very dense silty sand. Groundwater
was observed in the historical exploration at Southport at depths ranging from 3 to 10 feet below existing grade.
Preliminary estimates of cut and fill include approximately 25,000 cubic yards of excavation and 39,200 cubic yards of fill
from an approved source. The depth of excavation is anticipated to not exceed approximately two feet (2’) below ground
level, except for building cores where excavation would be deeper. Stormwater runoff from pollution generating surfaces
would be captured by catch basins and treated in cartridge filter facilities prior to connection into three (3) existing
drainage systems. No significant trees are proposed to be removed. Southport is proposing to plant 115 new trees along
with a variety of shrubs and perennials. The applicant has submitted a Preliminary Geotechnical Report, Technical
Information Report, Traffic Impact Analysis, and Stream Assessment and Final Mitigation Plan with the application.

PROJECT DESCRIPTION: The applicant, Southport West LLC, is requesting Master Plan Review, Hearing Examiner
Site Plan Review and Environmental (SEPA) Review for the construction of Southport West. Southport West is the
completion of the southerly portion of the Southport Development located at the south end of Lake Washington Blvd N.
The proposed expansion of Southport would be located on the 10.09-acre former Puget Sound Energy (PSE) Substation
and PSE utility parcels (APNs 082305-9191 and -9178). The two (2) parcels are located in the Urban Center-2 (UC-2) zone
and the Urban Design District ‘C’. The site is proposed to be developed as five (5) high-rise buildings with approximately
1,200,000 square feet of office and 50,000 of retail development in multiple phases. The proposed first three phases
would be developed as follows: Phase I – Towers 1 and 2 with the garage podium (July 2023 – July 2027), Phase II –
Towers 3 and 4 with garage podium (July 2027 – July 2031), and Phase III – Tower 5 (post July 2031). Phases 1-3 would
start on the south side of the site (closer to Boeing) and would develop to the north side of the lot (closer to Gene Coulon
Memorial Beach Park). A fourth and final phase is being considered for a sixth tower with 130,000 square feet for office
and retail at the south corner of the development near the intersection of Park Ave N and 757th Ave NE. The phased
development could reach as high as 1.6 million gross square feet. The proposed nine-level development would be built
at the same height and scale as the existing Southport offices with an overall height of approximately 154 feet above
average grade. Parking for 2,207 vehicles would be provided in a shared 4- and 5-level parking garage and 57 spaces are
proposed as on-street parking. In addition, the applicant is proposing to work closely with PSE for the engineering and

capacity needs of the development in order to relocate the powerlines and utility switchgear adjacent to Johns Creek.
Vehicular access to Southport West would be provided by Park Ave N, Lake Washington Blvd N, and the addition of an
internal center road and frontage road.
The site is generally level and consists of gravel yard and asphalt, a Puget Sound Energy switchgear, and an
office/warehouse building. The site contains high seismic hazard areas and the northeast corner of the site contains
Johns Creek and regulated slopes. The soil consists of a loose to medium dense sand, underlain by soft to medium dense
silt, then medium dense to dense sand, very soft silt and clay, and finally dense to very dense silty sand. Groundwater
was observed in the historical exploration at Southport at depths ranging from 3 to 10 feet below existing grade.
Preliminary estimates of cut and fill include approximately 25,000 cubic yards of excavation and 39,200 cubic yards of fill
from an approved source. The depth of excavation is anticipated to not exceed approximately two feet (2’) below ground
level, except for building cores where excavation would be deeper. Stormwater runoff from pollution generating surfaces
would be captured by catch basins and treated in cartridge filter facilities prior to connection into three (3) existing
drainage systems. No significant trees are proposed to be removed. Southport is proposing to plant 115 new trees along
with a variety of shrubs and perennials. The applicant has submitted a Preliminary Geotechnical Report, Technical
Information Report, Traffic Impact Analysis, and Stream Assessment and Final Mitigation Plan with the application.

PROJECT DESCRIPTION: The applicant, Southport West LLC, is requesting Master Plan Review, Hearing Examiner
Site Plan Review and Environmental (SEPA) Review for the construction of Southport West. Southport West is the
completion of the southerly portion of the Southport Development located at the south end of Lake Washington Blvd N.
The proposed expansion of Southport would be located on the 10.09-acre former Puget Sound Energy (PSE) Substation
and PSE utility parcels (APNs 082305-9191 and -9178). The two (2) parcels are located in the Urban Center-2 (UC-2) zone
and the Urban Design District ‘C’. The site is proposed to be developed as five (5) high-rise buildings with approximately
1,200,000 square feet of office and 50,000 of retail development in multiple phases. The proposed first three phases
would be developed as follows: Phase I – Towers 1 and 2 with the garage podium (July 2023 – July 2027), Phase II –
Towers 3 and 4 with garage podium (July 2027 – July 2031), and Phase III – Tower 5 (post July 2031). Phases 1-3 would
start on the south side of the site (closer to Boeing) and would develop to the north side of the lot (closer to Gene Coulon
Memorial Beach Park). A fourth and final phase is being considered for a sixth tower with 130,000 square feet for office
and retail at the south corner of the development near the intersection of Park Ave N and 757th Ave NE. The phased
development could reach as high as 1.6 million gross square feet. The proposed nine-level development would be built
at the same height and scale as the existing Southport offices with an overall height of approximately 154 feet above
average grade. Parking for 2,207 vehicles would be provided in a shared 4- and 5-level parking garage and 57 spaces are
proposed as on-street parking. In addition, the applicant is proposing to work closely with PSE for the engineering and

capacity needs of the development in order to relocate the powerlines and utility switchgear adjacent to Johns Creek.
Vehicular access to Southport West would be provided by Park Ave N, Lake Washington Blvd N, and the addition of an
internal center road and frontage road.
The site is generally level and consists of gravel yard and asphalt, a Puget Sound Energy switchgear, and an
office/warehouse building. The site contains high seismic hazard areas and the northeast corner of the site contains
Johns Creek and regulated slopes. The soil consists of a loose to medium dense sand, underlain by soft to medium dense
silt, then medium dense to dense sand, very soft silt and clay, and finally dense to very dense silty sand. Groundwater
was observed in the historical exploration at Southport at depths ranging from 3 to 10 feet below existing grade.
Preliminary estimates of cut and fill include approximately 25,000 cubic yards of excavation and 39,200 cubic yards of fill
from an approved source. The depth of excavation is anticipated to not exceed approximately two feet (2’) below ground
level, except for building cores where excavation would be deeper. Stormwater runoff from pollution generating surfaces
would be captured by catch basins and treated in cartridge filter facilities prior to connection into three (3) existing
drainage systems. No significant trees are proposed to be removed. Southport is proposing to plant 115 new trees along
with a variety of shrubs and perennials. The applicant has submitted a Preliminary Geotechnical Report, Technical
Information Report, Traffic Impact Analysis, and Stream Assessment and Final Mitigation Plan with the application.

PROJECT DESCRIPTION: The applicant, Southport West LLC, is requesting Master Plan Review, Hearing Examiner
Site Plan Review and Environmental (SEPA) Review for the construction of Southport West. Southport West is the
completion of the southerly portion of the Southport Development located at the south end of Lake Washington Blvd N.
The proposed expansion of Southport would be located on the 10.09-acre former Puget Sound Energy (PSE) Substation
and PSE utility parcels (APNs 082305-9191 and -9178). The two (2) parcels are located in the Urban Center-2 (UC-2) zone
and the Urban Design District ‘C’. The site is proposed to be developed as five (5) high-rise buildings with approximately
1,200,000 square feet of office and 50,000 of retail development in multiple phases. The proposed first three phases
would be developed as follows: Phase I – Towers 1 and 2 with the garage podium (July 2023 – July 2027), Phase II –
Towers 3 and 4 with garage podium (July 2027 – July 2031), and Phase III – Tower 5 (post July 2031). Phases 1-3 would
start on the south side of the site (closer to Boeing) and would develop to the north side of the lot (closer to Gene Coulon
Memorial Beach Park). A fourth and final phase is being considered for a sixth tower with 130,000 square feet for office
and retail at the south corner of the development near the intersection of Park Ave N and 757th Ave NE. The phased
development could reach as high as 1.6 million gross square feet. The proposed nine-level development would be built
at the same height and scale as the existing Southport offices with an overall height of approximately 154 feet above
average grade. Parking for 2,207 vehicles would be provided in a shared 4- and 5-level parking garage and 57 spaces are
proposed as on-street parking. In addition, the applicant is proposing to work closely with PSE for the engineering and

Vehicular access to Southport West would be provided by Park Ave N, Lake Washington Blvd N, and the addition of an
internal center road and frontage road.
The site is generally level and consists of gravel yard and asphalt, a Puget Sound Energy switchgear, and an
office/warehouse building. The site contains high seismic hazard areas and the northeast corner of the site contains
Johns Creek and regulated slopes. The soil consists of a loose to medium dense sand, underlain by soft to medium dense
silt, then medium dense to dense sand, very soft silt and clay, and finally dense to very dense silty sand. Groundwater
was observed in the historical exploration at Southport at depths ranging from 3 to 10 feet below existing grade.
Preliminary estimates of cut and fill include approximately 25,000 cubic yards of excavation and 39,200 cubic yards of fill
from an approved source. The depth of excavation is anticipated to not exceed approximately two feet (2’) below ground
level, except for building cores where excavation would be deeper. Stormwater runoff from pollution generating surfaces
would be captured by catch basins and treated in cartridge filter facilities prior to connection into three (3) existing

PROJECT DESCRIPTION: The applicant, Southport West LLC, is requesting Master Plan Review, Hearing Examiner
Site Plan Review and Environmental (SEPA) Review for the construction of Southport West. Southport West is the
completion of the southerly portion of the Southport Development located at the south end of Lake Washington Blvd N.
The proposed expansion of Southport would be located on the 10.09-acre former Puget Sound Energy (PSE) Substation
and PSE utility parcels (APNs 082305-9191 and -9178). The two (2) parcels are located in the Urban Center-2 (UC-2) zone
and the Urban Design District ‘C’. The site is proposed to be developed as five (5) high-rise buildings with approximately
1,200,000 square feet of office and 50,000 of retail development in multiple phases. The proposed first three phases
would be developed as follows: Phase I – Towers 1 and 2 with the garage podium (July 2023 – July 2027), Phase II –
Towers 3 and 4 with garage podium (July 2027 – July 2031), and Phase III – Tower 5 (post July 2031). Phases 1-3 would
start on the south side of the site (closer to Boeing) and would develop to the north side of the lot (closer to Gene Coulon
Memorial Beach Park). A fourth and final phase is being considered for a sixth tower with 130,000 square feet for office
and retail at the south corner of the development near the intersection of Park Ave N and 757th Ave NE. The phased
development could reach as high as 1.6 million gross square feet. The proposed nine-level development would be built
at the same height and scale as the existing Southport offices with an overall height of approximately 154 feet above
average grade. Parking for 2,207 vehicles would be provided in a shared 4- and 5-level parking garage and 57 spaces are
proposed as on-street parking. In addition, the applicant is proposing to work closely with PSE for the engineering and

capacity needs of the development in order to relocate the powerlines and utility switchgear adjacent to Johns Creek.
Vehicular access to Southport West would be provided by Park Ave N, Lake Washington Blvd N, and the addition of an
internal center road and frontage road.
The site is generally level and consists of gravel yard and asphalt, a Puget Sound Energy switchgear, and an
office/warehouse building. The site contains high seismic hazard areas and the northeast corner of the site contains
Johns Creek and regulated slopes. The soil consists of a loose to medium dense sand, underlain by soft to medium dense
silt, then medium dense to dense sand, very soft silt and clay, and finally dense to very dense silty sand. Groundwater
was observed in the historical exploration at Southport at depths ranging from 3 to 10 feet below existing grade.
Preliminary estimates of cut and fill include approximately 25,000 cubic yards of excavation and 39,200 cubic yards of fill
from an approved source. The depth of excavation is anticipated to not exceed approximately two feet (2’) below ground
level, except for building cores where excavation would be deeper. Stormwater runoff from pollution generating surfaces
would be captured by catch basins and treated in cartridge filter facilities prior to connection into three (3) existing
drainage systems. No significant trees are proposed to be removed. Southport is proposing to plant 115 new trees along
with a variety of shrubs and perennials. The applicant has submitted a Preliminary Geotechnical Report, Technical
Information Report, Traffic Impact Analysis, and Stream Assessment and Final Mitigation Plan with the application.

capacity needs of the development in order to relocate the powerlines and utility switchgear adjacent to Johns Creek.
Vehicular access to Southport West would be provided by Park Ave N, Lake Washington Blvd N, and the addition of an
internal center road and frontage road.
The site is generally level and consists of gravel yard and asphalt, a Puget Sound Energy switchgear, and an
office/warehouse building. The site contains high seismic hazard areas and the northeast corner of the site contains
Johns Creek and regulated slopes. The soil consists of a loose to medium dense sand, underlain by soft to medium dense
silt, then medium dense to dense sand, very soft silt and clay, and finally dense to very dense silty sand. Groundwater
was observed in the historical exploration at Southport at depths ranging from 3 to 10 feet below existing grade.
Preliminary estimates of cut and fill include approximately 25,000 cubic yards of excavation and 39,200 cubic yards of fill
from an approved source. The depth of excavation is anticipated to not exceed approximately two feet (2’) below ground
level, except for building cores where excavation would be deeper. Stormwater runoff from pollution generating surfaces
would be captured by catch basins and treated in cartridge filter facilities prior to connection into three (3) existing
drainage systems. No significant trees are proposed to be removed. Southport is proposing to plant 115 new trees along
with a variety of shrubs and perennials. The applicant has submitted a Preliminary Geotechnical Report, Technical
Information Report, Traffic Impact Analysis, and Stream Assessment and Final Mitigation Plan with the application.

PROJECT DESCRIPTION: The applicant, Southport West LLC, is requesting Master Plan Review, Hearing Examiner
Site Plan Review and Environmental (SEPA) Review for the construction of Southport West. Southport West is the
completion of the southerly portion of the Southport Development located at the south end of Lake Washington Blvd N.
The proposed expansion of Southport would be located on the 10.09-acre former Puget Sound Energy (PSE) Substation
and PSE utility parcels (APNs 082305-9191 and -9178). The two (2) parcels are located in the Urban Center-2 (UC-2) zone
and the Urban Design District ‘C’. The site is proposed to be developed as five (5) high-rise buildings with approximately
1,200,000 square feet of office and 50,000 of retail development in multiple phases. The proposed first three phases
would be developed as follows: Phase I – Towers 1 and 2 with the garage podium (July 2023 – July 2027), Phase II –
Towers 3 and 4 with garage podium (July 2027 – July 2031), and Phase III – Tower 5 (post July 2031). Phases 1-3 would
start on the south side of the site (closer to Boeing) and would develop to the north side of the lot (closer to Gene Coulon
Memorial Beach Park). A fourth and final phase is being considered for a sixth tower with 130,000 square feet for office
and retail at the south corner of the development near the intersection of Park Ave N and 757th Ave NE. The phased
development could reach as high as 1.6 million gross square feet. The proposed nine-level development would be built
at the same height and scale as the existing Southport offices with an overall height of approximately 154 feet above
average grade. Parking for 2,207 vehicles would be provided in a shared 4- and 5-level parking garage and 57 spaces are
proposed as on-street parking. In addition, the applicant is proposing to work closely with PSE for the engineering and

PROJECT DESCRIPTION: The applicant, Southport West LLC, is requesting Master Plan Review, Hearing Examiner
Site Plan Review and Environmental (SEPA) Review for the construction of Southport West. Southport West is the
completion of the southerly portion of the Southport Development located at the south end of Lake Washington Blvd N.
The proposed expansion of Southport would be located on the 10.09-acre former Puget Sound Energy (PSE) Substation
and PSE utility parcels (APNs 082305-9191 and -9178). The two (2) parcels are located in the Urban Center-2 (UC-2) zone
and the Urban Design District ‘C’. The site is proposed to be developed as five (5) high-rise buildings with approximately
1,200,000 square feet of office and 50,000 of retail development in multiple phases. The proposed first three phases
would be developed as follows: Phase I – Towers 1 and 2 with the garage podium (July 2023 – July 2027), Phase II –
Towers 3 and 4 with garage podium (July 2027 – July 2031), and Phase III – Tower 5 (post July 2031). Phases 1-3 would
start on the south side of the site (closer to Boeing) and would develop to the north side of the lot (closer to Gene Coulon
Memorial Beach Park). A fourth and final phase is being considered for a sixth tower with 130,000 square feet for office
and retail at the south corner of the development near the intersection of Park Ave N and 757th Ave NE. The phased
development could reach as high as 1.6 million gross square feet. The proposed nine-level development would be built
at the same height and scale as the existing Southport offices with an overall height of approximately 154 feet above
average grade. Parking for 2,207 vehicles would be provided in a shared 4- and 5-level parking garage and 57 spaces are
proposed as on-street parking. In addition, the applicant is proposing to work closely with PSE for the engineering and

capacity needs of the development in order to relocate the powerlines and utility switchgear adjacent to Johns Creek.
Vehicular access to Southport West would be provided by Park Ave N, Lake Washington Blvd N, and the addition of an
internal center road and frontage road.
The site is generally level and consists of gravel yard and asphalt, a Puget Sound Energy switchgear, and an
office/warehouse building. The site contains high seismic hazard areas and the northeast corner of the site contains
Johns Creek and regulated slopes. The soil consists of a loose to medium dense sand, underlain by soft to medium dense
silt, then medium dense to dense sand, very soft silt and clay, and finally dense to very dense silty sand. Groundwater
was observed in the historical exploration at Southport at depths ranging from 3 to 10 feet below existing grade.
Preliminary estimates of cut and fill include approximately 25,000 cubic yards of excavation and 39,200 cubic yards of fill
from an approved source. The depth of excavation is anticipated to not exceed approximately two feet (2’) below ground
level, except for building cores where excavation would be deeper. Stormwater runoff from pollution generating surfaces
would be captured by catch basins and treated in cartridge filter facilities prior to connection into three (3) existing
drainage systems. No significant trees are proposed to be removed. Southport is proposing to plant 115 new trees along
with a variety of shrubs and perennials. The applicant has submitted a Preliminary Geotechnical Report, Technical
Information Report, Traffic Impact Analysis, and Stream Assessment and Final Mitigation Plan with the application.

Towers 3 and 4 with garage podium (July 2027 – July 2031), and Phase III – Tower 5 (post July 2031). Phases 1-3 would
start on the south side of the site (closer to Boeing) and would develop to the north side of the lot (closer to Gene Coulon
Memorial Beach Park). A fourth and final phase is being considered for a sixth tower with 130,000 square feet for office
and retail at the south corner of the development near the intersection of Park Ave N and 757th Ave NE. The phased
development could reach as high as 1.6 million gross square feet. The proposed nine-level development would be built
at the same height and scale as the existing Southport offices with an overall height of approximately 154 feet above
average grade. Parking for 2,207 vehicles would be provided in a shared 4- and 5-level parking garage and 57 spaces are
proposed as on-street parking. In addition, the applicant is proposing to work closely with PSE for the engineering and

Vehicular access to Southport West would be provided by Park Ave N, Lake Washington Blvd N, and the addition of an
internal center road and frontage road.
The site is generally level and consists of gravel yard and asphalt, a Puget Sound Energy switchgear, and an
office/warehouse building. The site contains high seismic hazard areas and the northeast corner of the site contains
Johns Creek and regulated slopes. The soil consists of a loose to medium dense sand, underlain by soft to medium dense
silt, then medium dense to dense sand, very soft silt and clay, and finally dense to very dense silty sand. Groundwater
was observed in the historical exploration at Southport at depths ranging from 3 to 10 feet below existing grade.
Preliminary estimates of cut and fill include approximately 25,000 cubic yards of excavation and 39,200 cubic yards of fill
from an approved source. The depth of excavation is anticipated to not exceed approximately two feet (2’) below ground
level, except for building cores where excavation would be deeper. Stormwater runoff from pollution generating surfaces
would be captured by catch basins and treated in cartridge filter facilities prior to connection into three (3) existing
drainage systems. No significant trees are proposed to be removed. Southport is proposing to plant 115 new trees along
with a variety of shrubs and perennials. The applicant has submitted a Preliminary Geotechnical Report, Technical
Information Report, Traffic Impact Analysis, and Stream Assessment and Final Mitigation Plan with the application.

PROJECT DESCRIPTION: The applicant, Southport West LLC, is requesting Master Plan Review, Hearing Examiner
Site Plan Review and Environmental (SEPA) Review for the construction of Southport West. Southport West is the
completion of the southerly portion of the Southport Development located at the south end of Lake Washington Blvd N.
The proposed expansion of Southport would be located on the 10.09-acre former Puget Sound Energy (PSE) Substation
and PSE utility parcels (APNs 082305-9191 and -9178). The two (2) parcels are located in the Urban Center-2 (UC-2) zone
and the Urban Design District ‘C’. The site is proposed to be developed as five (5) high-rise buildings with approximately
1,200,000 square feet of office and 50,000 of retail development in multiple phases. The proposed first three phases
would be developed as follows: Phase I – Towers 1 and 2 with the garage podium (July 2023 – July 2027), Phase II –
Towers 3 and 4 with garage podium (July 2027 – July 2031), and Phase III – Tower 5 (post July 2031). Phases 1-3 would
start on the south side of the site (closer to Boeing) and would develop to the north side of the lot (closer to Gene Coulon
Memorial Beach Park). A fourth and final phase is being considered for a sixth tower with 130,000 square feet for office
and retail at the south corner of the development near the intersection of Park Ave N and 757th Ave NE. The phased
development could reach as high as 1.6 million gross square feet. The proposed nine-level development would be built
at the same height and scale as the existing Southport offices with an overall height of approximately 154 feet above
average grade. Parking for 2,207 vehicles would be provided in a shared 4- and 5-level parking garage and 57 spaces are
proposed as on-street parking. In addition, the applicant is proposing to work closely with PSE for the engineering and

capacity needs of the development in order to relocate the powerlines and utility switchgear adjacent to Johns Creek.
Vehicular access to Southport West would be provided by Park Ave N, Lake Washington Blvd N, and the addition of an
internal center road and frontage road.
The site is generally level and consists of gravel yard and asphalt, a Puget Sound Energy switchgear, and an
office/warehouse building. The site contains high seismic hazard areas and the northeast corner of the site contains
Johns Creek and regulated slopes. The soil consists of a loose to medium dense sand, underlain by soft to medium dense
silt, then medium dense to dense sand, very soft silt and clay, and finally dense to very dense silty sand. Groundwater
was observed in the historical exploration at Southport at depths ranging from 3 to 10 feet below existing grade.
Preliminary estimates of cut and fill include approximately 25,000 cubic yards of excavation and 39,200 cubic yards of fill
from an approved source. The depth of excavation is anticipated to not exceed approximately two feet (2’) below ground
level, except for building cores where excavation would be deeper. Stormwater runoff from pollution generating surfaces
would be captured by catch basins and treated in cartridge filter facilities prior to connection into three (3) existing
drainage systems. No significant trees are proposed to be removed. Southport is proposing to plant 115 new trees along
with a variety of shrubs and perennials. The applicant has submitted a Preliminary Geotechnical Report, Technical
Information Report, Traffic Impact Analysis, and Stream Assessment and Final Mitigation Plan with the application.

PROJECT DESCRIPTION: The applicant, Southport West LLC, is requesting Master Plan Review, Hearing Examiner
Site Plan Review and Environmental (SEPA) Review for the construction of Southport West. Southport West is the
completion of the southerly portion of the Southport Development located at the south end of Lake Washington Blvd N.
The proposed expansion of Southport would be located on the 10.09-acre former Puget Sound Energy (PSE) Substation
and PSE utility parcels (APNs 082305-9191 and -9178). The two (2) parcels are located in the Urban Center-2 (UC-2) zone
and the Urban Design District ‘C’. The site is proposed to be developed as five (5) high-rise buildings with approximately
1,200,000 square feet of office and 50,000 of retail development in multiple phases. The proposed first three phases
would be developed as follows: Phase I – Towers 1 and 2 with the garage podium (July 2023 – July 2027), Phase II –
Towers 3 and 4 with garage podium (July 2027 – July 2031), and Phase III – Tower 5 (post July 2031). Phases 1-3 would
start on the south side of the site (closer to Boeing) and would develop to the north side of the lot (closer to Gene Coulon
Memorial Beach Park). A fourth and final phase is being considered for a sixth tower with 130,000 square feet for office
and retail at the south corner of the development near the intersection of Park Ave N and 757th Ave NE. The phased
development could reach as high as 1.6 million gross square feet. The proposed nine-level development would be built
at the same height and scale as the existing Southport offices with an overall height of approximately 154 feet above
average grade. Parking for 2,207 vehicles would be provided in a shared 4- and 5-level parking garage and 57 spaces are
proposed as on-street parking. In addition, the applicant is proposing to work closely with PSE for the engineering and

capacity needs of the development in order to relocate the powerlines and utility switchgear adjacent to Johns Creek.
Vehicular access to Southport West would be provided by Park Ave N, Lake Washington Blvd N, and the addition of an
internal center road and frontage road.
The site is generally level and consists of gravel yard and asphalt, a Puget Sound Energy switchgear, and an
office/warehouse building. The site contains high seismic hazard areas and the northeast corner of the site contains
Johns Creek and regulated slopes. The soil consists of a loose to medium dense sand, underlain by soft to medium dense
silt, then medium dense to dense sand, very soft silt and clay, and finally dense to very dense silty sand. Groundwater
was observed in the historical exploration at Southport at depths ranging from 3 to 10 feet below existing grade.
Preliminary estimates of cut and fill include approximately 25,000 cubic yards of excavation and 39,200 cubic yards of fill
from an approved source. The depth of excavation is anticipated to not exceed approximately two feet (2’) below ground
level, except for building cores where excavation would be deeper. Stormwater runoff from pollution generating surfaces
would be captured by catch basins and treated in cartridge filter facilities prior to connection into three (3) existing
drainage systems. No significant trees are proposed to be removed. Southport is proposing to plant 115 new trees along
with a variety of shrubs and perennials. The applicant has submitted a Preliminary Geotechnical Report, Technical
Information Report, Traffic Impact Analysis, and Stream Assessment and Final Mitigation Plan with the application.

office/warehouse building. The site contains high seismic hazard areas and the northeast corner of the site contains
Johns Creek and regulated slopes. The soil consists of a loose to medium dense sand, underlain by soft to medium dense
silt, then medium dense to dense sand, very soft silt and clay, and finally dense to very dense silty sand. Groundwater
was observed in the historical exploration at Southport at depths ranging from 3 to 10 feet below existing grade.
Preliminary estimates of cut and fill include approximately 25,000 cubic yards of excavation and 39,200 cubic yards of fill
from an approved source. The depth of excavation is anticipated to not exceed approximately two feet (2’) below ground
level, except for building cores where excavation would be deeper. Stormwater runoff from pollution generating surfaces
would be captured by catch basins and treated in cartridge filter facilities prior to connection into three (3) existing
drainage systems. No significant trees are proposed to be removed. Southport is proposing to plant 115 new trees along
with a variety of shrubs and perennials. The applicant has submitted a Preliminary Geotechnical Report, Technical
Information Report, Traffic Impact Analysis, and Stream Assessment and Final Mitigation Plan with the application.

The proposed expansion of Southport would be located on the 10.09-acre former Puget Sound Energy (PSE) Substation
and PSE utility parcels (APNs 082305-9191 and -9178). The two (2) parcels are located in the Urban Center-2 (UC-2) zone
and the Urban Design District ‘C’. The site is proposed to be developed as five (5) high-rise buildings with approximately
1,200,000 square feet of office and 50,000 of retail development in multiple phases. The proposed first three phases
would be developed as follows: Phase I – Towers 1 and 2 with the garage podium (July 2023 – July 2027), Phase II –
Towers 3 and 4 with garage podium (July 2027 – July 2031), and Phase III – Tower 5 (post July 2031). Phases 1-3 would
start on the south side of the site (closer to Boeing) and would develop to the north side of the lot (closer to Gene Coulon
Memorial Beach Park). A fourth and final phase is being considered for a sixth tower with 130,000 square feet for office
and retail at the south corner of the development near the intersection of Park Ave N and 757th Ave NE. The phased
development could reach as high as 1.6 million gross square feet. The proposed nine-level development would be built
at the same height and scale as the existing Southport offices with an overall height of approximately 154 feet above
average grade. Parking for 2,207 vehicles would be provided in a shared 4- and 5-level parking garage and 57 spaces are
proposed as on-street parking. In addition, the applicant is proposing to work closely with PSE for the engineering and

PROJECT DESCRIPTION: The applicant, Southport West LLC, is requesting Master Plan Review, Hearing Examiner
Site Plan Review and Environmental (SEPA) Review for the construction of Southport West. Southport West is the
completion of the southerly portion of the Southport Development located at the south end of Lake Washington Blvd N.
The proposed expansion of Southport would be located on the 10.09-acre former Puget Sound Energy (PSE) Substation
and PSE utility parcels (APNs 082305-9191 and -9178). The two (2) parcels are located in the Urban Center-2 (UC-2) zone
and the Urban Design District ‘C’. The site is proposed to be developed as five (5) high-rise buildings with approximately
1,200,000 square feet of office and 50,000 of retail development in multiple phases. The proposed first three phases
would be developed as follows: Phase I – Towers 1 and 2 with the garage podium (July 2023 – July 2027), Phase II –
Towers 3 and 4 with garage podium (July 2027 – July 2031), and Phase III – Tower 5 (post July 2031). Phases 1-3 would
start on the south side of the site (closer to Boeing) and would develop to the north side of the lot (closer to Gene Coulon
Memorial Beach Park). A fourth and final phase is being considered for a sixth tower with 130,000 square feet for office
and retail at the south corner of the development near the intersection of Park Ave N and 757th Ave NE. The phased
development could reach as high as 1.6 million gross square feet. The proposed nine-level development would be built
at the same height and scale as the existing Southport offices with an overall height of approximately 154 feet above
average grade. Parking for 2,207 vehicles would be provided in a shared 4- and 5-level parking garage and 57 spaces are
proposed as on-street parking. In addition, the applicant is proposing to work closely with PSE for the engineering and

capacity needs of the development in order to relocate the powerlines and utility switchgear adjacent to Johns Creek.
Vehicular access to Southport West would be provided by Park Ave N, Lake Washington Blvd N, and the addition of an
internal center road and frontage road.
The site is generally level and consists of gravel yard and asphalt, a Puget Sound Energy switchgear, and an
office/warehouse building. The site contains high seismic hazard areas and the northeast corner of the site contains
Johns Creek and regulated slopes. The soil consists of a loose to medium dense sand, underlain by soft to medium dense
silt, then medium dense to dense sand, very soft silt and clay, and finally dense to very dense silty sand. Groundwater
was observed in the historical exploration at Southport at depths ranging from 3 to 10 feet below existing grade.
Preliminary estimates of cut and fill include approximately 25,000 cubic yards of excavation and 39,200 cubic yards of fill
from an approved source. The depth of excavation is anticipated to not exceed approximately two feet (2’) below ground
level, except for building cores where excavation would be deeper. Stormwater runoff from pollution generating surfaces
would be captured by catch basins and treated in cartridge filter facilities prior to connection into three (3) existing
drainage systems. No significant trees are proposed to be removed. Southport is proposing to plant 115 new trees along
with a variety of shrubs and perennials. The applicant has submitted a Preliminary Geotechnical Report, Technical
Information Report, Traffic Impact Analysis, and Stream Assessment and Final Mitigation Plan with the application.

capacity needs of the development in order to relocate the powerlines and utility switchgear adjacent to Johns Creek.
Vehicular access to Southport West would be provided by Park Ave N, Lake Washington Blvd N, and the addition of an
internal center road and frontage road.
The site is generally level and consists of gravel yard and asphalt, a Puget Sound Energy switchgear, and an
office/warehouse building. The site contains high seismic hazard areas and the northeast corner of the site contains
Johns Creek and regulated slopes. The soil consists of a loose to medium dense sand, underlain by soft to medium dense
silt, then medium dense to dense sand, very soft silt and clay, and finally dense to very dense silty sand. Groundwater
was observed in the historical exploration at Southport at depths ranging from 3 to 10 feet below existing grade.
Preliminary estimates of cut and fill include approximately 25,000 cubic yards of excavation and 39,200 cubic yards of fill
from an approved source. The depth of excavation is anticipated to not exceed approximately two feet (2’) below ground
level, except for building cores where excavation would be deeper. Stormwater runoff from pollution generating surfaces
would be captured by catch basins and treated in cartridge filter facilities prior to connection into three (3) existing
drainage systems. No significant trees are proposed to be removed. Southport is proposing to plant 115 new trees along
with a variety of shrubs and perennials. The applicant has submitted a Preliminary Geotechnical Report, Technical
Information Report, Traffic Impact Analysis, and Stream Assessment and Final Mitigation Plan with the application.

Site Plan Review and Environmental (SEPA) Review for the construction of Southport West. Southport West is the
completion of the southerly portion of the Southport Development located at the south end of Lake Washington Blvd N.
The proposed expansion of Southport would be located on the 10.09-acre former Puget Sound Energy (PSE) Substation
and PSE utility parcels (APNs 082305-9191 and -9178). The two (2) parcels are located in the Urban Center-2 (UC-2) zone
and the Urban Design District ‘C’. The site is proposed to be developed as five (5) high-rise buildings with approximately
1,200,000 square feet of office and 50,000 of retail development in multiple phases. The proposed first three phases
would be developed as follows: Phase I – Towers 1 and 2 with the garage podium (July 2023 – July 2027), Phase II –
Towers 3 and 4 with garage podium (July 2027 – July 2031), and Phase III – Tower 5 (post July 2031). Phases 1-3 would
start on the south side of the site (closer to Boeing) and would develop to the north side of the lot (closer to Gene Coulon
Memorial Beach Park). A fourth and final phase is being considered for a sixth tower with 130,000 square feet for office
and retail at the south corner of the development near the intersection of Park Ave N and 757th Ave NE. The phased
development could reach as high as 1.6 million gross square feet. The proposed nine-level development would be built
at the same height and scale as the existing Southport offices with an overall height of approximately 154 feet above
average grade. Parking for 2,207 vehicles would be provided in a shared 4- and 5-level parking garage and 57 spaces are

PROJECT DESCRIPTION: The applicant, Southport West LLC, is requesting Master Plan Review, Hearing Examiner
Site Plan Review and Environmental (SEPA) Review for the construction of Southport West. Southport West is the
completion of the southerly portion of the Southport Development located at the south end of Lake Washington Blvd N.
The proposed expansion of Southport would be located on the 10.09-acre former Puget Sound Energy (PSE) Substation
and PSE utility parcels (APNs 082305-9191 and -9178). The two (2) parcels are located in the Urban Center-2 (UC-2) zone
and the Urban Design District ‘C’. The site is proposed to be developed as five (5) high-rise buildings with approximately
1,200,000 square feet of office and 50,000 of retail development in multiple phases. The proposed first three phases
would be developed as follows: Phase I – Towers 1 and 2 with the garage podium (July 2023 – July 2027), Phase II –
Towers 3 and 4 with garage podium (July 2027 – July 2031), and Phase III – Tower 5 (post July 2031). Phases 1-3 would
start on the south side of the site (closer to Boeing) and would develop to the north side of the lot (closer to Gene Coulon
Memorial Beach Park). A fourth and final phase is being considered for a sixth tower with 130,000 square feet for office
and retail at the south corner of the development near the intersection of Park Ave N and 757th Ave NE. The phased
development could reach as high as 1.6 million gross square feet. The proposed nine-level development would be built
at the same height and scale as the existing Southport offices with an overall height of approximately 154 feet above
average grade. Parking for 2,207 vehicles would be provided in a shared 4- and 5-level parking garage and 57 spaces are
proposed as on-street parking. In addition, the applicant is proposing to work closely with PSE for the engineering and

capacity needs of the development in order to relocate the powerlines and utility switchgear adjacent to Johns Creek.
Vehicular access to Southport West would be provided by Park Ave N, Lake Washington Blvd N, and the addition of an
internal center road and frontage road.
The site is generally level and consists of gravel yard and asphalt, a Puget Sound Energy switchgear, and an
office/warehouse building. The site contains high seismic hazard areas and the northeast corner of the site contains
Johns Creek and regulated slopes. The soil consists of a loose to medium dense sand, underlain by soft to medium dense
silt, then medium dense to dense sand, very soft silt and clay, and finally dense to very dense silty sand. Groundwater
was observed in the historical exploration at Southport at depths ranging from 3 to 10 feet below existing grade.
Preliminary estimates of cut and fill include approximately 25,000 cubic yards of excavation and 39,200 cubic yards of fill
from an approved source. The depth of excavation is anticipated to not exceed approximately two feet (2’) below ground
level, except for building cores where excavation would be deeper. Stormwater runoff from pollution generating surfaces
would be captured by catch basins and treated in cartridge filter facilities prior to connection into three (3) existing
drainage systems. No significant trees are proposed to be removed. Southport is proposing to plant 115 new trees along
with a variety of shrubs and perennials. The applicant has submitted a Preliminary Geotechnical Report, Technical
Information Report, Traffic Impact Analysis, and Stream Assessment and Final Mitigation Plan with the application.

and the Urban Design District ‘C’. The site is proposed to be developed as five (5) high-rise buildings with approximately
1,200,000 square feet of office and 50,000 of retail development in multiple phases. The proposed first three phases
would be developed as follows: Phase I – Towers 1 and 2 with the garage podium (July 2023 – July 2027), Phase II –
Towers 3 and 4 with garage podium (July 2027 – July 2031), and Phase III – Tower 5 (post July 2031). Phases 1-3 would
start on the south side of the site (closer to Boeing) and would develop to the north side of the lot (closer to Gene Coulon
Memorial Beach Park). A fourth and final phase is being considered for a sixth tower with 130,000 square feet for office
and retail at the south corner of the development near the intersection of Park Ave N and 757th Ave NE. The phased
development could reach as high as 1.6 million gross square feet. The proposed nine-level development would be built
at the same height and scale as the existing Southport offices with an overall height of approximately 154 feet above
average grade. Parking for 2,207 vehicles would be provided in a shared 4- and 5-level parking garage and 57 spaces are
proposed as on-street parking. In addition, the applicant is proposing to work closely with PSE for the engineering and

capacity needs of the development in order to relocate the powerlines and utility switchgear adjacent to Johns Creek.
Vehicular access to Southport West would be provided by Park Ave N, Lake Washington Blvd N, and the addition of an
internal center road and frontage road.
The site is generally level and consists of gravel yard and asphalt, a Puget Sound Energy switchgear, and an
office/warehouse building. The site contains high seismic hazard areas and the northeast corner of the site contains
Johns Creek and regulated slopes. The soil consists of a loose to medium dense sand, underlain by soft to medium dense
silt, then medium dense to dense sand, very soft silt and clay, and finally dense to very dense silty sand. Groundwater
was observed in the historical exploration at Southport at depths ranging from 3 to 10 feet below existing grade.
Preliminary estimates of cut and fill include approximately 25,000 cubic yards of excavation and 39,200 cubic yards of fill
from an approved source. The depth of excavation is anticipated to not exceed approximately two feet (2’) below ground
level, except for building cores where excavation would be deeper. Stormwater runoff from pollution generating surfaces
would be captured by catch basins and treated in cartridge filter facilities prior to connection into three (3) existing
drainage systems. No significant trees are proposed to be removed. Southport is proposing to plant 115 new trees along
with a variety of shrubs and perennials. The applicant has submitted a Preliminary Geotechnical Report, Technical
Information Report, Traffic Impact Analysis, and Stream Assessment and Final Mitigation Plan with the application.

PROJECT DESCRIPTION: The applicant, Southport West LLC, is requesting Master Plan Review, Hearing Examiner
Site Plan Review and Environmental (SEPA) Review for the construction of Southport West. Southport West is the
completion of the southerly portion of the Southport Development located at the south end of Lake Washington Blvd N.
The proposed expansion of Southport would be located on the 10.09-acre former Puget Sound Energy (PSE) Substation
and PSE utility parcels (APNs 082305-9191 and -9178). The two (2) parcels are located in the Urban Center-2 (UC-2) zone
and the Urban Design District ‘C’. The site is proposed to be developed as five (5) high-rise buildings with approximately
1,200,000 square feet of office and 50,000 of retail development in multiple phases. The proposed first three phases
would be developed as follows: Phase I – Towers 1 and 2 with the garage podium (July 2023 – July 2027), Phase II –
Towers 3 and 4 with garage podium (July 2027 – July 2031), and Phase III – Tower 5 (post July 2031). Phases 1-3 would
start on the south side of the site (closer to Boeing) and would develop to the north side of the lot (closer to Gene Coulon
Memorial Beach Park). A fourth and final phase is being considered for a sixth tower with 130,000 square feet for office
and retail at the south corner of the development near the intersection of Park Ave N and 757th Ave NE. The phased
development could reach as high as 1.6 million gross square feet. The proposed nine-level development would be built
at the same height and scale as the existing Southport offices with an overall height of approximately 154 feet above
average grade. Parking for 2,207 vehicles would be provided in a shared 4- and 5-level parking garage and 57 spaces are
proposed as on-street parking. In addition, the applicant is proposing to work closely with PSE for the engineering and

capacity needs of the development in order to relocate the powerlines and utility switchgear adjacent to Johns Creek.
Vehicular access to Southport West would be provided by Park Ave N, Lake Washington Blvd N, and the addition of an
internal center road and frontage road.
The site is generally level and consists of gravel yard and asphalt, a Puget Sound Energy switchgear, and an
office/warehouse building. The site contains high seismic hazard areas and the northeast corner of the site contains
Johns Creek and regulated slopes. The soil consists of a loose to medium dense sand, underlain by soft to medium dense
silt, then medium dense to dense sand, very soft silt and clay, and finally dense to very dense silty sand. Groundwater
was observed in the historical exploration at Southport at depths ranging from 3 to 10 feet below existing grade.
Preliminary estimates of cut and fill include approximately 25,000 cubic yards of excavation and 39,200 cubic yards of fill
from an approved source. The depth of excavation is anticipated to not exceed approximately two feet (2’) below ground
level, except for building cores where excavation would be deeper. Stormwater runoff from pollution generating surfaces
would be captured by catch basins and treated in cartridge filter facilities prior to connection into three (3) existing
drainage systems. No significant trees are proposed to be removed. Southport is proposing to plant 115 new trees along
with a variety of shrubs and perennials. The applicant has submitted a Preliminary Geotechnical Report, Technical
Information Report, Traffic Impact Analysis, and Stream Assessment and Final Mitigation Plan with the application.

PROJECT DESCRIPTION: The applicant, Southport West LLC, is requesting Master Plan Review, Hearing Examiner
Site Plan Review and Environmental (SEPA) Review for the construction of Southport West. Southport West is the
completion of the southerly portion of the Southport Development located at the south end of Lake Washington Blvd N.
The proposed expansion of Southport would be located on the 10.09-acre former Puget Sound Energy (PSE) Substation
and PSE utility parcels (APNs 082305-9191 and -9178). The two (2) parcels are located in the Urban Center-2 (UC-2) zone
and the Urban Design District ‘C’. The site is proposed to be developed as five (5) high-rise buildings with approximately
1,200,000 square feet of office and 50,000 of retail development in multiple phases. The proposed first three phases
would be developed as follows: Phase I – Towers 1 and 2 with the garage podium (July 2023 – July 2027), Phase II –
Towers 3 and 4 with garage podium (July 2027 – July 2031), and Phase III – Tower 5 (post July 2031). Phases 1-3 would
start on the south side of the site (closer to Boeing) and would develop to the north side of the lot (closer to Gene Coulon
Memorial Beach Park). A fourth and final phase is being considered for a sixth tower with 130,000 square feet for office
and retail at the south corner of the development near the intersection of Park Ave N and 757th Ave NE. The phased
development could reach as high as 1.6 million gross square feet. The proposed nine-level development would be built
at the same height and scale as the existing Southport offices with an overall height of approximately 154 feet above
average grade. Parking for 2,207 vehicles would be provided in a shared 4- and 5-level parking garage and 57 spaces are
proposed as on-street parking. In addition, the applicant is proposing to work closely with PSE for the engineering and

capacity needs of the development in order to relocate the powerlines and utility switchgear adjacent to Johns Creek.
Vehicular access to Southport West would be provided by Park Ave N, Lake Washington Blvd N, and the addition of an
internal center road and frontage road.
The site is generally level and consists of gravel yard and asphalt, a Puget Sound Energy switchgear, and an
office/warehouse building. The site contains high seismic hazard areas and the northeast corner of the site contains
Johns Creek and regulated slopes. The soil consists of a loose to medium dense sand, underlain by soft to medium dense
silt, then medium dense to dense sand, very soft silt and clay, and finally dense to very dense silty sand. Groundwater
was observed in the historical exploration at Southport at depths ranging from 3 to 10 feet below existing grade.
Preliminary estimates of cut and fill include approximately 25,000 cubic yards of excavation and 39,200 cubic yards of fill
from an approved source. The depth of excavation is anticipated to not exceed approximately two feet (2’) below ground
level, except for building cores where excavation would be deeper. Stormwater runoff from pollution generating surfaces
would be captured by catch basins and treated in cartridge filter facilities prior to connection into three (3) existing
drainage systems. No significant trees are proposed to be removed. Southport is proposing to plant 115 new trees along
with a variety of shrubs and perennials. The applicant has submitted a Preliminary Geotechnical Report, Technical
Information Report, Traffic Impact Analysis, and Stream Assessment and Final Mitigation Plan with the application.

The site is generally level and consists of gravel yard and asphalt, a Puget Sound Energy switchgear, and an
office/warehouse building. The site contains high seismic hazard areas and the northeast corner of the site contains
Johns Creek and regulated slopes. The soil consists of a loose to medium dense sand, underlain by soft to medium dense
silt, then medium dense to dense sand, very soft silt and clay, and finally dense to very dense silty sand. Groundwater
was observed in the historical exploration at Southport at depths ranging from 3 to 10 feet below existing grade.
Preliminary estimates of cut and fill include approximately 25,000 cubic yards of excavation and 39,200 cubic yards of fill
from an approved source. The depth of excavation is anticipated to not exceed approximately two feet (2’) below ground
level, except for building cores where excavation would be deeper. Stormwater runoff from pollution generating surfaces
would be captured by catch basins and treated in cartridge filter facilities prior to connection into three (3) existing
drainage systems. No significant trees are proposed to be removed. Southport is proposing to plant 115 new trees along
with a variety of shrubs and perennials. The applicant has submitted a Preliminary Geotechnical Report, Technical
Information Report, Traffic Impact Analysis, and Stream Assessment and Final Mitigation Plan with the application.

The proposed expansion of Southport would be located on the 10.09-acre former Puget Sound Energy (PSE) Substation
and PSE utility parcels (APNs 082305-9191 and -9178). The two (2) parcels are located in the Urban Center-2 (UC-2) zone
and the Urban Design District ‘C’. The site is proposed to be developed as five (5) high-rise buildings with approximately
1,200,000 square feet of office and 50,000 of retail development in multiple phases. The proposed first three phases
would be developed as follows: Phase I – Towers 1 and 2 with the garage podium (July 2023 – July 2027), Phase II –
Towers 3 and 4 with garage podium (July 2027 – July 2031), and Phase III – Tower 5 (post July 2031). Phases 1-3 would
start on the south side of the site (closer to Boeing) and would develop to the north side of the lot (closer to Gene Coulon
Memorial Beach Park). A fourth and final phase is being considered for a sixth tower with 130,000 square feet for office
and retail at the south corner of the development near the intersection of Park Ave N and 757th Ave NE. The phased
development could reach as high as 1.6 million gross square feet. The proposed nine-level development would be built
at the same height and scale as the existing Southport offices with an overall height of approximately 154 feet above
average grade. Parking for 2,207 vehicles would be provided in a shared 4- and 5-level parking garage and 57 spaces are
proposed as on-street parking. In addition, the applicant is proposing to work closely with PSE for the engineering and

PROJECT DESCRIPTION: The applicant, Southport West LLC, is requesting Master Plan Review, Hearing Examiner
Site Plan Review and Environmental (SEPA) Review for the construction of Southport West. Southport West is the
completion of the southerly portion of the Southport Development located at the south end of Lake Washington Blvd N.
The proposed expansion of Southport would be located on the 10.09-acre former Puget Sound Energy (PSE) Substation
and PSE utility parcels (APNs 082305-9191 and -9178). The two (2) parcels are located in the Urban Center-2 (UC-2) zone
and the Urban Design District ‘C’. The site is proposed to be developed as five (5) high-rise buildings with approximately
1,200,000 square feet of office and 50,000 of retail development in multiple phases. The proposed first three phases
would be developed as follows: Phase I – Towers 1 and 2 with the garage podium (July 2023 – July 2027), Phase II –
Towers 3 and 4 with garage podium (July 2027 – July 2031), and Phase III – Tower 5 (post July 2031). Phases 1-3 would
start on the south side of the site (closer to Boeing) and would develop to the north side of the lot (closer to Gene Coulon
Memorial Beach Park). A fourth and final phase is being considered for a sixth tower with 130,000 square feet for office
and retail at the south corner of the development near the intersection of Park Ave N and 757th Ave NE. The phased
development could reach as high as 1.6 million gross square feet. The proposed nine-level development would be built
at the same height and scale as the existing Southport offices with an overall height of approximately 154 feet above
average grade. Parking for 2,207 vehicles would be provided in a shared 4- and 5-level parking garage and 57 spaces are
proposed as on-street parking. In addition, the applicant is proposing to work closely with PSE for the engineering and

capacity needs of the development in order to relocate the powerlines and utility switchgear adjacent to Johns Creek.
Vehicular access to Southport West would be provided by Park Ave N, Lake Washington Blvd N, and the addition of an
internal center road and frontage road.
The site is generally level and consists of gravel yard and asphalt, a Puget Sound Energy switchgear, and an
office/warehouse building. The site contains high seismic hazard areas and the northeast corner of the site contains
Johns Creek and regulated slopes. The soil consists of a loose to medium dense sand, underlain by soft to medium dense
silt, then medium dense to dense sand, very soft silt and clay, and finally dense to very dense silty sand. Groundwater
was observed in the historical exploration at Southport at depths ranging from 3 to 10 feet below existing grade.
Preliminary estimates of cut and fill include approximately 25,000 cubic yards of excavation and 39,200 cubic yards of fill
from an approved source. The depth of excavation is anticipated to not exceed approximately two feet (2’) below ground
level, except for building cores where excavation would be deeper. Stormwater runoff from pollution generating surfaces
would be captured by catch basins and treated in cartridge filter facilities prior to connection into three (3) existing
drainage systems. No significant trees are proposed to be removed. Southport is proposing to plant 115 new trees along
with a variety of shrubs and perennials. The applicant has submitted a Preliminary Geotechnical Report, Technical
Information Report, Traffic Impact Analysis, and Stream Assessment and Final Mitigation Plan with the application.

Vehicular access to Southport West would be provided by Park Ave N, Lake Washington Blvd N, and the addition of an
internal center road and frontage road.
The site is generally level and consists of gravel yard and asphalt, a Puget Sound Energy switchgear, and an
office/warehouse building. The site contains high seismic hazard areas and the northeast corner of the site contains
Johns Creek and regulated slopes. The soil consists of a loose to medium dense sand, underlain by soft to medium dense
silt, then medium dense to dense sand, very soft silt and clay, and finally dense to very dense silty sand. Groundwater
was observed in the historical exploration at Southport at depths ranging from 3 to 10 feet below existing grade.
Preliminary estimates of cut and fill include approximately 25,000 cubic yards of excavation and 39,200 cubic yards of fill
from an approved source. The depth of excavation is anticipated to not exceed approximately two feet (2’) below ground
level, except for building cores where excavation would be deeper. Stormwater runoff from pollution generating surfaces
would be captured by catch basins and treated in cartridge filter facilities prior to connection into three (3) existing
drainage systems. No significant trees are proposed to be removed. Southport is proposing to plant 115 new trees along
with a variety of shrubs and perennials. The applicant has submitted a Preliminary Geotechnical Report, Technical
Information Report, Traffic Impact Analysis, and Stream Assessment and Final Mitigation Plan with the application.

The proposed expansion of Southport would be located on the 10.09-acre former Puget Sound Energy (PSE) Substation
and PSE utility parcels (APNs 082305-9191 and -9178). The two (2) parcels are located in the Urban Center-2 (UC-2) zone
and the Urban Design District ‘C’. The site is proposed to be developed as five (5) high-rise buildings with approximately
1,200,000 square feet of office and 50,000 of retail development in multiple phases. The proposed first three phases
would be developed as follows: Phase I – Towers 1 and 2 with the garage podium (July 2023 – July 2027), Phase II –
Towers 3 and 4 with garage podium (July 2027 – July 2031), and Phase III – Tower 5 (post July 2031). Phases 1-3 would
start on the south side of the site (closer to Boeing) and would develop to the north side of the lot (closer to Gene Coulon
Memorial Beach Park). A fourth and final phase is being considered for a sixth tower with 130,000 square feet for office
and retail at the south corner of the development near the intersection of Park Ave N and 757th Ave NE. The phased
development could reach as high as 1.6 million gross square feet. The proposed nine-level development would be built
at the same height and scale as the existing Southport offices with an overall height of approximately 154 feet above
average grade. Parking for 2,207 vehicles would be provided in a shared 4- and 5-level parking garage and 57 spaces are

PROJECT DESCRIPTION: The applicant, Southport West LLC, is requesting Master Plan Review, Hearing Examiner
Site Plan Review and Environmental (SEPA) Review for the construction of Southport West. Southport West is the
completion of the southerly portion of the Southport Development located at the south end of Lake Washington Blvd N.
The proposed expansion of Southport would be located on the 10.09-acre former Puget Sound Energy (PSE) Substation
and PSE utility parcels (APNs 082305-9191 and -9178). The two (2) parcels are located in the Urban Center-2 (UC-2) zone
and the Urban Design District ‘C’. The site is proposed to be developed as five (5) high-rise buildings with approximately
1,200,000 square feet of office and 50,000 of retail development in multiple phases. The proposed first three phases
would be developed as follows: Phase I – Towers 1 and 2 with the garage podium (July 2023 – July 2027), Phase II –
Towers 3 and 4 with garage podium (July 2027 – July 2031), and Phase III – Tower 5 (post July 2031). Phases 1-3 would
start on the south side of the site (closer to Boeing) and would develop to the north side of the lot (closer to Gene Coulon
Memorial Beach Park). A fourth and final phase is being considered for a sixth tower with 130,000 square feet for office
and retail at the south corner of the development near the intersection of Park Ave N and 757th Ave NE. The phased
development could reach as high as 1.6 million gross square feet. The proposed nine-level development would be built
at the same height and scale as the existing Southport offices with an overall height of approximately 154 feet above
average grade. Parking for 2,207 vehicles would be provided in a shared 4- and 5-level parking garage and 57 spaces are
proposed as on-street parking. In addition, the applicant is proposing to work closely with PSE for the engineering and

capacity needs of the development in order to relocate the powerlines and utility switchgear adjacent to Johns Creek.
Vehicular access to Southport West would be provided by Park Ave N, Lake Washington Blvd N, and the addition of an
internal center road and frontage road.
The site is generally level and consists of gravel yard and asphalt, a Puget Sound Energy switchgear, and an
office/warehouse building. The site contains high seismic hazard areas and the northeast corner of the site contains
Johns Creek and regulated slopes. The soil consists of a loose to medium dense sand, underlain by soft to medium dense
silt, then medium dense to dense sand, very soft silt and clay, and finally dense to very dense silty sand. Groundwater
was observed in the historical exploration at Southport at depths ranging from 3 to 10 feet below existing grade.
Preliminary estimates of cut and fill include approximately 25,000 cubic yards of excavation and 39,200 cubic yards of fill
from an approved source. The depth of excavation is anticipated to not exceed approximately two feet (2’) below ground
level, except for building cores where excavation would be deeper. Stormwater runoff from pollution generating surfaces
would be captured by catch basins and treated in cartridge filter facilities prior to connection into three (3) existing
drainage systems. No significant trees are proposed to be removed. Southport is proposing to plant 115 new trees along
with a variety of shrubs and perennials. The applicant has submitted a Preliminary Geotechnical Report, Technical
Information Report, Traffic Impact Analysis, and Stream Assessment and Final Mitigation Plan with the application.

and the Urban Design District ‘C’. The site is proposed to be developed as five (5) high-rise buildings with approximately
1,200,000 square feet of office and 50,000 of retail development in multiple phases. The proposed first three phases
would be developed as follows: Phase I – Towers 1 and 2 with the garage podium (July 2023 – July 2027), Phase II –
Towers 3 and 4 with garage podium (July 2027 – July 2031), and Phase III – Tower 5 (post July 2031). Phases 1-3 would
start on the south side of the site (closer to Boeing) and would develop to the north side of the lot (closer to Gene Coulon
Memorial Beach Park). A fourth and final phase is being considered for a sixth tower with 130,000 square feet for office
and retail at the south corner of the development near the intersection of Park Ave N and 757th Ave NE. The phased
development could reach as high as 1.6 million gross square feet. The proposed nine-level development would be built
at the same height and scale as the existing Southport offices with an overall height of approximately 154 feet above
average grade. Parking for 2,207 vehicles would be provided in a shared 4- and 5-level parking garage and 57 spaces are
proposed as on-street parking. In addition, the applicant is proposing to work closely with PSE for the engineering and

capacity needs of the development in order to relocate the powerlines and utility switchgear adjacent to Johns Creek.
Vehicular access to Southport West would be provided by Park Ave N, Lake Washington Blvd N, and the addition of an
internal center road and frontage road.
The site is generally level and consists of gravel yard and asphalt, a Puget Sound Energy switchgear, and an
office/warehouse building. The site contains high seismic hazard areas and the northeast corner of the site contains
Johns Creek and regulated slopes. The soil consists of a loose to medium dense sand, underlain by soft to medium dense
silt, then medium dense to dense sand, very soft silt and clay, and finally dense to very dense silty sand. Groundwater
was observed in the historical exploration at Southport at depths ranging from 3 to 10 feet below existing grade.
Preliminary estimates of cut and fill include approximately 25,000 cubic yards of excavation and 39,200 cubic yards of fill
from an approved source. The depth of excavation is anticipated to not exceed approximately two feet (2’) below ground
level, except for building cores where excavation would be deeper. Stormwater runoff from pollution generating surfaces
would be captured by catch basins and treated in cartridge filter facilities prior to connection into three (3) existing
drainage systems. No significant trees are proposed to be removed. Southport is proposing to plant 115 new trees along
with a variety of shrubs and perennials. The applicant has submitted a Preliminary Geotechnical Report, Technical
Information Report, Traffic Impact Analysis, and Stream Assessment and Final Mitigation Plan with the application.

PROJECT DESCRIPTION: The applicant, Southport West LLC, is requesting Master Plan Review, Hearing Examiner
Site Plan Review and Environmental (SEPA) Review for the construction of Southport West. Southport West is the
completion of the southerly portion of the Southport Development located at the south end of Lake Washington Blvd N.
The proposed expansion of Southport would be located on the 10.09-acre former Puget Sound Energy (PSE) Substation
and PSE utility parcels (APNs 082305-9191 and -9178). The two (2) parcels are located in the Urban Center-2 (UC-2) zone
and the Urban Design District ‘C’. The site is proposed to be developed as five (5) high-rise buildings with approximately
1,200,000 square feet of office and 50,000 of retail development in multiple phases. The proposed first three phases
would be developed as follows: Phase I – Towers 1 and 2 with the garage podium (July 2023 – July 2027), Phase II –
Towers 3 and 4 with garage podium (July 2027 – July 2031), and Phase III – Tower 5 (post July 2031). Phases 1-3 would
start on the south side of the site (closer to Boeing) and would develop to the north side of the lot (closer to Gene Coulon
Memorial Beach Park). A fourth and final phase is being considered for a sixth tower with 130,000 square feet for office
and retail at the south corner of the development near the intersection of Park Ave N and 757th Ave NE. The phased
development could reach as high as 1.6 million gross square feet. The proposed nine-level development would be built
at the same height and scale as the existing Southport offices with an overall height of approximately 154 feet above
average grade. Parking for 2,207 vehicles would be provided in a shared 4- and 5-level parking garage and 57 spaces are
proposed as on-street parking. In addition, the applicant is proposing to work closely with PSE for the engineering and

capacity needs of the development in order to relocate the powerlines and utility switchgear adjacent to Johns Creek.
Vehicular access to Southport West would be provided by Park Ave N, Lake Washington Blvd N, and the addition of an
internal center road and frontage road.
The site is generally level and consists of gravel yard and asphalt, a Puget Sound Energy switchgear, and an
office/warehouse building. The site contains high seismic hazard areas and the northeast corner of the site contains
Johns Creek and regulated slopes. The soil consists of a loose to medium dense sand, underlain by soft to medium dense
silt, then medium dense to dense sand, very soft silt and clay, and finally dense to very dense silty sand. Groundwater
was observed in the historical exploration at Southport at depths ranging from 3 to 10 feet below existing grade.
Preliminary estimates of cut and fill include approximately 25,000 cubic yards of excavation and 39,200 cubic yards of fill
from an approved source. The depth of excavation is anticipated to not exceed approximately two feet (2’) below ground
level, except for building cores where excavation would be deeper. Stormwater runoff from pollution generating surfaces
would be captured by catch basins and treated in cartridge filter facilities prior to connection into three (3) existing
drainage systems. No significant trees are proposed to be removed. Southport is proposing to plant 115 new trees along
with a variety of shrubs and perennials. The applicant has submitted a Preliminary Geotechnical Report, Technical
Information Report, Traffic Impact Analysis, and Stream Assessment and Final Mitigation Plan with the application.
