ENVIRONMENTAL REVIEW COMMITTEE REPORT
ERC Meeting Date: April 5, 2022
Project File Number: PR21-000051
Project Name: SWA2 Amazon
Land Use File Number: LUA21-000233, SA-A, SME, ECF
Project Manager: Alex Morganroth, Senior Planner
Owner: Western B Northwest WA, LLC, 602 W Office Center Drive, Ste 200, Fort Washington,
PA 19034
Applicant/Contact: Paul Gierlach, CESO / 175 Montrose West Ave / Akron, OH 44321 / paulg@cesoinc.com
Project Location: 1905 Raymond Ave SW (APN 2423049115)
Project Summary: The applicant, Amazon, is requesting Site Plan Review, Environmental (SEPA) Review,
and a Shoreline Exemption for minor site work and tenant improvements in a 126,600 -
sq. ft. existing industrial building at 1905 Raymond Ave SW (APN 2423049115). The
building was previously occupied by DHL Global Forwarding, a shipping service. The
applicant intends to use the building for its “Amazon Flex” delivery service, in which
contract employees pick up packages from the site in their personal, passenger vehicles
and distribute (i.e. deliver) the packages to customers in the Renton area. The proposal
is subject to Environmental (SEPA) Review due to the scope including the addition of new
parking stalls in an existing parking lot with over 20 stalls. In addition, the project site is
encumbered by critical areas. The proposed work within the shoreline, the installation
of a bicycle rack, is an exempt action due to the value of the work falling under the fair
market value threshold as outlined in WAC 173-27-040. The applicant has proposed to
retain the existing office space for use by support staff, while updating the
warehouse/distribution space to better meet the needs of the flex delivery service. The
building is located on the north half of a 6.8 acre site near the corner of SW 19th St and
Raymond Ave SW. The subject site is located in the Industrial, Light (IL) zone and
Employment Area Comprehensive Plan Land Use designation. According to the
applicant, all works would be interior except for parking lot re-striping and minor
concrete work that would add a total of 26 new parking stalls as well as new ADA ramps
and crosswalks. No trees or vegetation are proposed for removal as part of the project.
According to COR Maps, multiple critical areas are present on the site including a high
seismic hazard, sensitive slopes, a special flood hazard area (FEMA zone AE), and an
unclassified wetland. In addition, the eastern portion of the site is located within Reach
C of the Black River/Springbrook Creek Regulated Shoreline Area and has an
environmental designation of Shoreline High Intensity. According to the applicant, the
project would result in a net impervious surface increase of approximately 127 sq. ft.

D. Environmental Impacts
The Proposal was circulated and reviewed by various City Departments and Divisions to determine whether or not
the applicant has adequately identified and addressed environmental impacts anticipated to occur in conjunction
with the proposed development. Staff reviewers have identified that the proposal is likely to have the following
probable impacts:
1. Earth
Impacts: According to COR Maps, high seismic hazard and sensitive slopes are present on the project site.
The applicant has indicated the project would result in approximately 127 sq. ft. of replaced impervious
area. All changes to the building are interior only and therefore a geotechnical report was not required as
part fo the land use application . The project would be required to demonstrate compliance with the
structural design requirements in the 2018 International Building Code for sites with seismic hazards at
the time of building permit review. Therefore no specific mitigation measures are recommended.
Mitigation Measures: No further mitigation recommended.
Nexus: Not applicable.
2. Water
Wetland, Streams, Lakes

Report of April 5, 2022 Page 4 of 8
SR_ERC Report_Amazon SWA2_220330_v4_FINAL Report_Amazon SWA2_220330_v4_FINAL
Impacts: An unclassified wetland and a special flood hazard area are present on the south side of the site.
In addition, Reach C of the Black River/Springbrook Creek, a regulated shoreline area, extends onto the
eastern portion of the site. The portion of the site within the regulated shoreline area has an
environmental designation of Shoreline High Intensity. Minor ground disturbance would occur between
the existing building and the internal looped road near the southeast side of the site in order to construct
five (5) new parking stalls. In addition, an existing sport court on the south side of the site would be
removed in order to provide pervious surface area for passive recreation. No expansion to the existing
building is proposed and new structures or impervious surface is proposed between Spring Brook Creek
and wetlands, and the looped internal roadway, a lawfully intervening structure constructed as part of
the original stie and building development in 1997. Due to the limited site improvements proposed and
location of the proposed site improvements between the existing building and looped internal road, no
significant impacts are anticipated as a result of the projec t.
Mitigation Measures: No further mitigation recommended.
Nexus: Not applicable.
3. Transportation
Impacts: The proposed project is anticipated to generate more than 20 new PM peak hour trips and
therefore, the applicant submitted a revised Traffic Impact Analysis prepared by NV5 and dated October
28, 2021 (Exhibit 4) with the application. Primary access to the site is provided via the existing single access
driveway located just southwest of the intersection of Raymond Ave SW and SW 19th St. As noted in the
TIA, the prospective tenant has a unique operation that is different from those included in the Institute of
Transportation Engineers (ITE) trip generation manual, 10th Edition. Trip generation provided by the
tenant is based on their planned employee head count, delivery operation, and line-haul movements.
According to the analysis, the proposed development is estimated to generate 3,129 new daily trips,
including 341 AM peak hour trips (171 entering, 170 exiting) from 7:00 – 8:00 AM, and 180 PM peak hour
trips (102 entering, 78 exiting) from 4:00 – 5:00 PM. Trips were assigned to the existing City streets at the
study intersections based on the assumption that most of the traffic is destined to and from I -5 to the
west and SR-167 to the east. City staff concurs with the trip generation and trip assignment outlined in
the report.
The report evaluated 23 nearby intersections and utilized three (3) study periods for the evaluation
including 2021 Existing, 2025 Horizon Year No -Build, and 2025 Horizon Year Build. Study area roadways
included Raymond Ave SW, SW 19th St, Lind Ave SW, SW 16th St, SW Grady Way, Oakesdale Ave SW
Interurban Avenue S, and WA-167/Rainier Ave S. The intersections were evaluated using Level of Service
(LOS) methodology under existing conditions, existing plus project conditions, and project opening year
conditions. LOS evaluation was done in accordance with the industry standard Highway Capacity Ma nual
(HCM) Sixth Edition. The turning movements counted were obtained by StreetLight Data, Inc. in 2019 to
capture pre-pandemic traffic patterns. From this data, existing LOS was determined for each intersection.
The report concludes that in the existing condition 16 out of the 23 intersections evaluated operate with
an approach or overall LOS below D during at least one (1) peak hour. In addition to those intersections
and movements operating inadequately during Existing Conditions, Oakesdale Ave SW and SW 16th St is
expected to operate poorly by the Horizon Year 2025, with LOS below D during at least one (1) peak hour.
For the 2025 Horizon Year Build traffic conditions analyzed with the existing intersection control and lane
configurations, the expected project traffic is expected to add minor delay to the roadway network, but
no new intersections are expected to deteriorate from adequate LOS to inadequate LOS due to the
addition of expected project traffic to the roadway network. According to the report, the intersection of
Raymond Ave SW and SW 19th St is expected to perform at LOS A but has safety concerns.
The report recommends five (5) specific mitigation measures designed to alleviate safety concerns and
poor traffic conditions anticipated to occur wi th a 2025 Build scenario.

1) The report recommends that the westbound approach of SW 19th St, currently only 18-feet wide, be
widened to safely accommodate traffic. Specifically, the westbound approach width of SW 19th St
should be widened to a minimum of 20 feet (two (2) 10-foot lanes). Additionally, the provision of
advanced warning signage on the westbound approach of SW 19th St and the southbound approach
of Raymond Ave SW is recommended. Measures to improve sight distance such as trimming
shrubbery/vegetation in the immediate vicinity of the intersection is also included as a
recommendation.
A categorized wetland is located south of the existing SW 19 th St ROW. Per RMC 4-3-050, overbuilding
(enlargement beyond existing project needs) or replacement of existing utility systems and
replacement and/or rehabilitation of existing streets, provided the work does not increase the
footprint of the structure, line or street by more than ten percent (1 0%) within the critical area and/or
buffer areas, and occurs in the existing right-of-way boundary or easement boundary. In addition, per
WAC 197-97-800, the construction or installation of minor road and street improvements by any
agency or private party is a SEPA exempt action if any certain conditions are met.
2) According to the report, a traffic signal at the intersection of Lind Ave SW and SW 19th St is warranted
with significant right-turning traffic anticipated and with expected project traffic added to the
roadway network. The installation of a traffic signal at Lind Ave SW and SW 19th St is expected to
provide much improved adequate LOS over the existing intersection control of a conventional side
street stop.
3) The report recommends the installation of a roundabout at the intersection of Raymond Ave SW and
SW 16th St. According to the report, a roundabout would provide much improved adequate LOS over
the existing lane geometry and intersection control of a conventional side street stop. The applicant
provided a conceptual design for the roundabout (Exhibit 10) that indicates adequate existing ROW is
available at the intersection for construction of the improvement.
4) According to the report, the intersections in the study area currently experiencing inadequate LOS
during Existing Conditions and/or No-Build conditions are still expected to do so with the addition o f
site traffic in a 2025 Build scenario. However, as the site traffic departs further from the site, the
percentage of site traffic relative to the over-all traffic already on the corridors decreases. In addition,
almost all the intersection locations are in dense areas that would require significant disruption to
existing developments. Therefore, further physical improvements, geometric or otherwise, are not
recommended for the remaining inadequate intersections. The report recommends that an Adaptive
Traffic Control System (ATCS) Split Cycle Offset Optimization Technique (SCOOT) to assist with
consistent flows along the mainline corridors in the area be implemented at the following
intersections including Oakesdale Ave SW and SW Grady Way, Oakesdale Ave SW and SW 16th St,
Lind Ave SW and SW Grady Way, and Lind Ave SW and SW 16th St.
5) The report recommends the construction of an eastbound right turn lane at the intersection of
Oakesdale Ave SW and SW Grady Way. In reviewing the proposed mitigation, staff dete rmined the
additional right turn lane would result in marginal improvements to the intersection but would require
significant impacts on the adjacent Springbrook Creek located at the southwest corner of the
intersection. The intersection would be improved adequately with the addition of the SCOOT system
recommended under a separate mitigation measure and therefore staff does not recommend the
addition of the right turn lane at this time.
Staff concurs with recommended mitigation measures one through four (1-4) noted above, but
recommends adjustments to measures #1 and #3. For measure #1, staff recommends the applicant
be required to install vertical curb and gutter on the north side of SW 19 th St (westbound approach)
that aligns with the existing curb and gutter east of the intersection (appx 225 linear fee). In addition,
staff also recommends the applicant be required to construct ADA ramps at the intersection of
Raymond Ave SW and SW 19th St. For measure #3, staff recommends the traffic signal recommended

at the intersection of Lind Ave SW and SW 19th St be constructed in a way that accommodates the
future construction of an additional 11-foot lane on Lind Avenue SW.
A WSDOT representative, Duffy McColloch, submitted comments in response to the initial and follow-
up traffic impact analysis submitted by the applicant (Exhibits 6 and 7). The comments were primarily
related to concerns over the limited study area and included a recommendation to expand the study
area and subsequent number of intersections included in the analysis. City staff shared similar
concerns and requested the applicant update the analysis based on the study area comments and
others. WSDOT reviewed the updated traffic impact analysis used as basis for the C ity’s recommended
mitigation measures and determined that their concerns had been adequately addressed (Exhibit 8).
No specific mitigation measures were recommended by WSDOT.
Parking on the site would remain substantially similar to the current layout with some minor restriping
proposed in order provide parking closer to the building for the contract drivers. The existing parking
lot contains approximately 190 spaces. Five (5) new spaces are proposed at the southeast corner of
the building in addition to eleven other new spaces created by the restriping, resulting in a total of
206 spaces. The project does not take direct access off of an existing public right of way therefore no
frontage improvements are required for the project as it relates to Renton Mun icipal Code (RMC) 4-
6-060. An easement across the site to the east allows access to SW 19 th St and Raymond Ave SW for
vehicles.
The proposed project passes the City’s Transportation Concurrency test based upon the test of the
citywide Transportation Plan, consideration of growth levels included in the LOS‐tested
Transportation Plan, payment of a Transportation Mitigation Fee, and an applicatio n of site-specific
mitigation (Exhibit 5).
Increased traffic created by the development would be mitigated by paym ent of transportation
impact fees. The transportation impact fee that is current at the time of building permi t application
will be levied.
Mitigation Measures:
1) The applicant shall construct the following improvements at the intersection of Raymond Ave SW
and SW 19th St:
a. Widen the westbound approach of SW 19th St by constructing vertical curb and gutter to
match alignment of the existing curb, providing a minimum of twenty feet (20’) of
pavement;
b. Construct ADA compliant curb ramps at the NE corner of Raymond Ave SW and SW 19th St
intersection and associated companion ramps ;
c. Provide advanced warning signage on the westbound approach of SW 19 th St and the
southbound approach of Raymond Ave SW;
d. Trim vegetation in the immediate vicinity of the intersection to improve sight distance.
The final design of the improvements shall be reviewed and approved by the Development
Engineering Project Manager prior to implementation. The improvements shall be fully constructed
prior to issuance of a Temporary Certificate of Occupancy (TCO).
2. The applicant shall install a traffic signal at the intersection of Lind Ave SW and SW 19 th St. The traffic
signal shall be designed in a manner that accommodates the future construction of an additional 11 -
foot lane on Lind Ave SW. The final design of the traffic signal infrastructure shall be reviewed and
approved by the Development Engineering Project Manager. The signalization of the intersection shall
be implemented and operational prior to issuance of a TCO.
3. The applicant shall construct a roundabout at the intersection of Raymond Ave SW and SW 16 th St.
The final design of the roundabout shall be reviewed and approved by the Development Engineering
Project Manager. The roundabout shall be constructed prior to issuance of a TCO.

4. Environmental Health
Impacts: Staff received a letter from the Department of Ecology (DOE) dated Ju ly 7, 2021 (Exhibit 9) regarding
the proposed project. In the letter, the agency identifies the project site as being located in an area that may
have been contaminated with heavy metals due to the air emissions originating from the old Asarco smelter
in north Tacoma. The letter requests that the SEPA lead agency (City of Renton) include three (3) mitigation
measures as part of the threshold determination related to entry into th e agency’s Voluntary Clean-up
Program (VCP) under the Washington Model Toxics Control Act.
Staff confirmed that the Tacoma Smelter Plume map indicates the potential presence of heavy metals on
the site, as is similar to a large swath of Renton’s jurisdicti onal area. Therefore, staff recommends a
mitigation measure that the applicant be required to sample soil for arsenic and lead following 2019 Tacoma
Smelter Plume Guidance. If lead or arsenic are found at concentrations above the Model Toxics Control Act
(MTCA) cleanup level, construction workers and employees on site shall be notified of their occurrence.
Mitigation Measures: The applicant shall sample soil for arsenic and lead following 2019 Tacoma Smelter
Plume Guidance. If lead or arsenic are found at concentrations above the Model Toxics Control Act (MTCA)
cleanup level, construction workers and employees on site shall be notified of their occurrence.
