Description of Proposal: The new Renton High School (RHS) campus will expand to the north
and east of the historic Renton High School campus. The Renton School District (RSD) recently
acquired 42 parcels (see below) adjacent to the RHS campus in order to facilitate site expansion
and the shifting of the buildings and taller structures to the eastern portions of the campus, which
is to avoid affecting the FAA Navigable Airspace for Renton Municipal Airport and comply with
the City’s Airport Height and Use Restrictions. Most of the structures on the newly acquired
parcels are currently under demolition. These parcels add to the size of the RHS campus, which
after dedication of frontages to the City for right of way, will be 33.6 acres.
The proposal will retain the existing 1930s historic high school building, and the interior will be
renovated for RSD/RHS Support uses. The IKEA Performing Arts Center (IPAC) will also be
preserved, while the existing classroom additions, gymnasium, and warehouse will be
demolished. A new, three-story 310,000 SF classroom building will be constructed fronting on
Logan Ave S and S 2nd St. This includes a new gymnasium that will be constructed to the north
of the new classroom portion of the building. Other structures include 960 SF concessions
building, a 4,500 SF storage building and an 810 SF grounds maintenance building, as well as
batting cages for both softball and baseball.
The proposal includes improvements to RHS athletic fields, courts and amenities. It will add a
standard competition size baseball and softball field and a multipurpose football/soccer/lacrosse
practice field in the northern portion of the campus. The fields in this portion of the campus will
have synthetic turf with underdrains and field lighting. The existing multipurpose field located in

the western portion of campus (that currently supports three baseball, one soccer field and
spectator seating) will remain in the same location but will be renovated to provide only practice
track and field facilities with no spectator seating. This field will have a grass infield with
underdrains and will not be lit due to the RMA airspace restrictions. The district is proposing to
add two additional tennis courts, two outdoor half-court basketball courts and three outdoor
pickleball courts that will be available for public use. These facilities will be unlit.
The proposal will provide approximately 476 staff/visitor/student parking spaces and four small
bus spaces. There will be 21 bus parking spaces provided along Logan Ave that can be used
after-hours for 47 standard vehicle parking spaces. Parking for special events can be
accommodated in the northwestern portion of the site for approximately 48 spaces. The proposal
will require a street vacation for a portion of S Tobin St and S Tillicum St. It will also require a
consolidation of all lots that comprise the RHS campus into one lot. The street vacation and lot
consolidation will be processed following PUD approval.
The proposed project would reconfigure access and parking for the overall campus. The
segments of S Tobin St and S Tillicum St between Shattuck Ave S and Logan Ave S are
proposed to be vacated to create a consolidated school property. Access to the campus will be via
an expanded drop-off/pick-up lane on S 2nd St; at S 2nd St near the intersection of Lake Ave S;
at Lake Ave S; and at the intersection of S Tobin St and Shattuck Ave S. School buses will
load/unload in a pullout lane on Logan Ave S.
Students will remain onsite during construction. School capacity will increase from 1,389 to
1,600 students; however, enrollment levels (currently 1,208 students) are not anticipated to
increase in the near-term.
Location of Proposal: The properties comprising the expanded campus are located in Township
23 North, Range 5 East, Section 18, Willamette Meridian, U.S. Geological Survey (USGS)
Renton Topographic Quadrangle. They are comprised of 44 tax parcels as follows: 722930-

CAPITAL PLANNING
AND CONSTRUCTION
1. Earth - The sites where work will occur is flat with less than 5% grade. The site is underlain by
Urban Land (Ur) soils, which are soils that have been modified and filled. Following proposed
demolition, the acquired parcels will be hydroseeded or stabilized with straw depending on site
conditions grading will be limited to sight contouring at areas of backfill until project/site
development. The area is in a high risk seismic hazard area and soils are subject to liquefaction,
which will require mitigation for site work and aggregate pier footings for the buildings.
Approximately 40,000 cubic yards of fill are expected and will be sourced from a City approved
fill source, and 4,900 CY of cut are anticipated. Approximately 74 percent of the completed
project will be impervious (including under-drained athletic fields). Temporary erosion control
measures will be in place to ensure earthwork does not cause erosion impacts. A TESC Plan and
SWPPP will be prepared as part of the construction permit application.
2. Air – Best Management Practices will be employed to minimize dust-related emissions during
construction. New emissions generated by the completed project will be related to vehicle
emissions. Because the school is existing, any increase in vehicle emissions are anticipated to be
low and not significant. If asbestos-containing materials are discovered in the buildings to be
demolished, all city, state and federal regulations will be followed to ensure proper handling and
disposal of those materials to control release to the air.
3. Water – There are no surface water bodies on the site; the Cedar River is approximately 280 feet
northeast of the site. The site does not lie within a 100-year floodplain. After construction, runoff
will be collected and conveyed in underground pipes to stormwater treatment systems and
detention pipe systems before being directed to the city’s stormwater system. Temporary erosion
control measures will be employed during construction and detailed in a Temporary Erosion
Control Plan (TESC). The project will protect water quality by directing runoff from pollution
generating surfaces to manufactured treatment devices.
4. Plants – The site contains 212 significant trees (both deciduous and evergreen) as well as
variable vegetation typical of an urban landscape. Most of the existing vegetation will be
removed and replaced using native vegetation. Twenty-eight (28) of the significant trees will be
retained. Most of the landmark trees along S 2nd Ave and Airport Way will be retained.
Planting also avoids vegetation that attracts wildlife per FAA regulations. Code-required
perimeter landscape buffers and parking lot landscaping will be provided. In accordance with
RMC 4-4-130(H).10, tree protection fencing, root discovery, and pruning methods will be
employed during construction and any pruning needed for clearance will follow industry standard
practices. The best management practices for tree protection during construction, which are
detailed in the Tree Retention Report, shall be followed. To compensate for tree removal above
the code-required minimum, and as allowed per RMC 4-4-130(J)4.e, the District will pay an “in-
lieu” fee into the city’s Urban Forestry Program fund.
5. Environmental Health – School operation is not anticipated to generate environmental health
hazards. Due to the age of the buildings to be demolished, they are suspected to contain
hazardous building materials and there may be some underground storage tanks. Hazardous
materials testing will be completed for the structures prior to demolition and the safe handling

AND CONSTRUCTION
and disposal of the materials will follow state and local regulations and the recommendations of
the hazardous materials survey. Underground storage tanks will be removed and disposed of in
compliance with all pertinent regulations. There is known petroleum contamination associated
with the previous removal of an underground storage tank located at 307 Airport Way that is
awaiting cleanup (Cleanup Site ID 9972, Facility Site ID 63618514). The District will follow the
Dept. of Ecology requirements for cleanup.
6. Noise – Temporary, short term noise impacts will occur typical of construction activity. Some
vibration may be felt during geo-pier installation. Construction will be phased beginning in the
summer of 2025 and concluding in fall of 2029. Construction will occur between the hours of
7:00 am and 5:00 pm. Following construction noise levels are anticipated to be similar to existing
and not significant.
7. Land and Shoreline Use – The area in which this project is occurring is part of downtown
Renton, and the current uses in the vicinity range from the existing high school campus to older
single-family homes and large, newer mixed-use buildings. All of the existing structures on the
Renton High School campus will be demolished with the exception of the Main Classroom
Building (1930’s building) and the IKEA Performing Arts Center. The expanded site is
comprised of several zoning districts (Center Downtown, Commercial Arterial and Residential-8
and is within Urban Design Districts A and D, Airspace Protection Zone, and the Downtown
Business District. The property is within a High Seismic Hazard Area and Wellhead Protection
Areas 1 and 2. Employment is expected to remain at current levels in the near term but increase
in the long term to approximately 120 full time and 30 part time staff. Overall, the Campus
expansion has resulted in the displacement of 39 residential units, or approximately 99 people.
Campus expansion related to the SEPA Phase 3 properties has resulted in the displacement of 8
residential units, or approximately 20 people, who were compensated fairly and provided
relocation assistance. The proposal is designed in consideration of the City Center Plan
requirements, including its main entry location at the corner of S 2nd St and Logan Ave S and
wider pedestrian paths and sidewalks are provided.
8. Aesthetics – The new high school building will be approximately 65 feet in height at its highest
point. Building materials will be complementary with the 1930s high school and IKEA
Performing Arts Center buildings and comprised of two blends of masonry bricks, metal panels,
corrugated metal siding and glazing systems including aluminum curtain wall and storefront.
The new athletic fields in the northeast corner of the site will have field lighting with heights
varying from 46 to 75 feet. No views will be obstructed by the proposal. The site and building
have been designed to meet the City of Renton’s Urban Design District A and D requirements.
9. Light and Glare – Light and glare will generally occur during the early evening hours,
consistent with what is present on the current campus, and what is expected of a similar use. The
buildings, parking lots and pathways will be lit for safety and security after dusk. The athletic
fields will be lit when they are in use from dusk until approximately 10pm during the darker
months of the year. Street/sidewalk lighting will be provided in accordance with city
requirements. Light spill to adjacent rights of way and residential properties is anticipated to be

AND CONSTRUCTION
within acceptable levels and less than 0.09 footcandles. Light fixtures will be shielded and
downcast to minimize light spill. Field lights will be turned off by 10 pm when in use during the
darker months of the year.
10. Historic and cultural preservation –Most of the structures to be demolished are more than 45
years old. In consultation with DAHP, those on the Renton High School campus were
determined eligible for listing in the National Register of Historic Places as a historic district.
The project will retain the oldest and most significant built-environment feature of the campus,
the 1932 main building (as well as the 2003 IKEA PAC). The later additions to the main
building, the gym building, the warehouse and the playfield are to be demolished, which
constitutes an adverse environmental impact under SEPA. In addition, the project will impact the
Moses family homestead archaeological site, which has not been evaluated for listing in the
NRHP. Three other historic-period debris scatters or concentrations that have not been evaluated
for listing in the NRHP, and one historic-period debris scatter that HRA recommended as not
eligible for listing in the NRHP, will also be disturbed by the project.
The RHS campus and acquisition area has been investigated for the presence of archaeological
resources many times as the area is known to be the location of a former channel of the Cedar
River and tribal occupation, as well as a former historic-period homestead. It is also modeled by
the Department of Historic Preservation (DAHP) as being of high risk for discovery of cultural
artifacts. The RHS campus and vicinity have also been extensively modified throughout the
twentieth century with the construction of and modifications to RHS and its associated athletic
fields and infrastructure, as well as development on residential and commercial properties north
and east of the RHS campus.
Studies prepared for the proposal include a Built Environment Inventory Report, and a Cultural
Resources Assessment and two Addendums by Historical Research Associates, Inc. (HRA).
Additional Addendum reports are in process. HRA’s work has identified archaeological sites
within the project’s area of impacts.
These reports were distributed to area Tribes and the Washington Dept. of Archaeologic and
Historic Preservation (DAHP) for review and comment. The reports document the results of
onsite built environment survey, archaeological survey and archaeological monitoring and
includes recommendations for measures that will be implemented by the District in order to
minimize disturbance to cultural resources. The Duwamish Tribe and the Snoqualmie Tribe of
Indians, at their request, have been and will continue to be invited to observe and monitor all
ground disturbances. An archaeological monitoring and inadvertent discovery plan (MIDP) will
be in place.
The District is considering multiple opportunities to highlight the history and past land use on the
property and in Renton more broadly to mitigate the Project’s impacts on the archaeological sites
and historic built-environment properties within the campus. The District has recently held two
meetings with DAHP and interested Tribes to review potential mitigation measures. Project
changes have been made as a result to minimize impacts by raising the grade and relocating

underground infrastructure on portions of the property. The District will be required to obtain a
DAHP Archaeological Site Alteration and Excavation Permit prior to ground-disturbing activities
for impacts to precontact sites and any NRHP-eligible or potentially eligible historic period
archaeological sites.
11. Transportation – The proposed project would reconfigure access and parking for the overall
campus. The segments of S Tobin St and S Tillicum St between Shattuck and Logan Ave S
would be vacated to create a consolidated school property. Vehicular access is proposed via two
(2) driveways on S 2nd St, one driveway on Lake Ave S and gated/event access at Logan Ave S
and S Tobin St, with pedestrian circulation improved through frontage improvements and off-site
intersection upgrades. School bus load/unload would be relocated to a proposed new curb-side
load zone along the west side of Logan Ave S. All access driveways that currently serve the
existing uses would be absorbed into the expanded site and removed.
The site is served by several King County Metro bus routes and is located approximately 500 feet
from the City Center Parking Garage and Renton Transit Center.
The proposal will make right of way dedications, frontage improvements and replace/install new
accessible curb ramps. Pedestrian actuated Rectangular Rapid Flashing Beacon (RRFB) or half-
signal will be provided at the intersection of Logan Ave S and S Tobin St.
The traffic analysis detailed in the Transportation Technical Report reflected conditions with the
Renton High School Replacement project complete and increased enrollment to its planned
capacity of up to 1,600 students (a net increase of 211 students compared to the school’s current
enrollment capacity). The proposal at its planned capacity of up to 1,600 students is anticipated to
generate 410 new trips per day (205 in/205 out). The peak volumes would continue to occur in
the morning before classes begin (net increase of 114 trips between 6:45 and 7:45 AM) and in the
afternoon around dismissal (net increase of 72 trips between 1:45 and 2:45 PM). The number of
school buses could increase by 3 to 5 buses. Truck trips will continue to provide food and supply
deliveries, track pick up and occasional maintenance. School and small trucks represent about 3
to 5 percent of the total daily traffic.
THRESHOLD DETERMINATION: In reaching the Threshold Determination, the
Responsible Official reviewed the completed environmental checklist, environmental
information on file with RSD, City of Renton, and public/agency comments, relying on the
information therein to exercise substantive authority under the Washington State Environmental
Policy Act, pursuant to RCW 43.21C.060. This Mitigated Determination of Nonsignificance
(MDNS) is issued under the Washington Administrative Code (WAC) 197-11-350 and pursuant
to the criteria and procedures of WAC 197-11-300 through 197-11-350 and 197-11-390. The
Responsible Official has determined that the proposal does not have a probable significant
adverse impact with adherence to local, state, and federal regulations.

MITIGATION MEASURES:
1. To mitigate and reduce the erosion hazard and potential for off-site sediment transport, the
following recommendations of the geotechnical engineer (see Draft Geotechnical Report
dated Sept. 2025 prepared by AESI, or as updated) shall be followed:
a. Construction activity should be scheduled or phased as much as possible to avoid
earthwork activity during the wet season.
b. The winder performance of the site is dependent on a well-conceived plan for control of
site erosion and stormwater runoff. The site plan should include ground-cover measures
and staging areas. The contractor should be prepared to implement and maintain the
required measures to reduce the amount of exposed ground.
c. TESC elements and perimeter flow control should be established prior to the start of
grading. This should include, but is not limited to, silt fencing, swales with check dams,
rocked construction entrance, etc.
d. During the wetter months of the year, or when significant storm events are predicted
during the summer months, the work area should be stabilized so that if showers occur, it
can receive the rainfall without excessive erosion or sediment transport. The required
measures for an area to be “buttoned-up” will depend on the time of year and the duration
that the area will be left unworked. During the winter months, areas that are to be left
unworked for more than 2 days should be mulched or covered with plastic. During the
summer months, stabilization will usually consist of seal-rolling the subgrade. Such
measures will aid in the contractor’s ability to get back into a work area after a storm
event. The stabilization process also includes establishing temporary stormwater
conveyance channels through work areas to route runoff to the approved
treatment/discharge facilities.
e. Surface runoff and discharge should be controlled during and following development.
Uncontrolled discharge may promote erosion and sediment transport.
f. Soils that are to be reused around the site should be stored in such a manner as to reduce
erosion from the stockpile. Protective measures may include, but are not limited to,
covering stockpiles with plastic sheeting, or the use of silt fences around stockpile
perimeters.
2. To mitigate the risk of liquefaction-induced settlement, the geotechnical engineer
recommends ground improvements for the building foundation as detailed in their August
2025 Geotechnical Report.
3. During construction, measures shall be applied to limit emissions to the air; which may
include limiting the idling of construction equipment, water sprays to control dust, limiting
vehicle speeds, and general maintenance of construction equipment.

4. Care will be taken during construction to avoid spills or leaks of petroleum-based products or
chemicals used for construction. The contractor will follow due diligence processes to
evaluate and, as necessary, mitigate potential impacts identified. Contractors will be required
to comply with all applicable health and safety regulations, including State of Washington
Department of Labor and Industries General Occupational Health Standards, Chapter 296-62
WAC, and General Safety and Health Standards, Chapter 296-24 WAC.
5. The removal of hazardous building materials requires compliance with asbestos abatement
laws, including Washington Dept. of Labor and Industries requirements, Puget Sound Clean
Air Agency requirements and the recommendations provided in the Hazardous Building
Materials Surveys.
6. If during excavation and construction, soils are found to be contaminated with arsenic, lead,
or other contaminants, extra precaution will be taken to avoid escaping dust, soil, erosion,
and water pollution during grading and site construction. Contaminated soils generated
during site construction shall be managed and disposed of in accordance with state and local
regulations, including the Solid Waste Handling Standards regulation (WAC Chapter 173-
350).
7. Proper cleanup of the contaminated soils associated with Cleanup Site ID 972, Facility Site
ID 63618514 is to be completed in accordance with the requirements of Dept. of Ecology.
8. If Underground Storage Tanks are found, they shall be removed in accordance with Dept. of
Ecology procedures.
9. All imported fill must be clean fill utilizing an approved source.
10. A Construction General Stormwater permit is to be obtained prior to clearing, grading, or
excavation activities.
11. The field light fixtures are to be shielded, downcast and aimed to the play area to minimize
light spill. Additionally, lighting will be turned off by 10 pm when in use during the darker
months of the year.
12. The following mitigation measures will be implementing to avoid or minimize disturbance to
historic and archaeological resources:
a. If required, the north wall replacement planned for the 1930’s building shall be
undertaken in accordance with the Secretary of Interior Standards for the Treatment of
Historic Properties and National Park Service Brief 14, New Exterior Additions to
Historic Buildings.
b. Additional archaeological work shall be conducted to evaluate historic-period
archaeological sites’ eligibility for listing in the NRHP and assess impacts from the

project. Evaluation of the eligible-for-listing historic period sites and mitigation for
impacts to those resources will occur prior to disturbance.
c. The District will minimize impacts to historic and cultural resources in the vicinity of
known archaeological and historic sites by modifying the grading and drainage plans
to raise ground elevations and relocating, where possible, underground infrastructure.
d. Demolition on the newly acquired (SEPA Phase 3) parcels, the school buildings and
all ground disturbing activities shall proceed with a monitoring and inadvertent
discovery plan (MIDP) in place. The MIDP shall make it clear that no precontact
archaeological resource(s) may be disturbed without a permit from DAHP and that no
historic-period archaeological resource that is eligible for listing in the National
Register of Historic Places (NRHP) may be disturbed without a permit from DAHP.
The MIDP includes explicit expectations for what would make a historic-period site
eligible for listing in the NRHP.
e. In the event that additional cultural materials are identified during ground-disturbing
activities that would change HRA’s interpretation of the historic-period archaeological
sites’ NRHP eligibility, the activities shall be halted to allow HRA’s archaeologists to
evaluate. If determined eligible for listing on the NRHP, a permit from DAHP will be
required to conduct further work within the site(s) boundary.
f. Per their request, the Duwamish Tribe and the Snoqualmie Tribe of Indians shall be
notified prior to ground-disturbing activities so that they can be present when an
archaeologist is onsite. The list of tribes receiving advance notifications may be
expanded at the request of the other tribes.
g. Archaeological survey shall be conducted on the recently-acquired parcels (SEPA
Phase 3 properties) consistent with the Project’s archaeological work plan (McNulty
Perez and Kraemer 2024). Other Addendum reports shall be prepared documenting the
results of the additional study. The results of the additional archaeological survey(s)
will be submitted to DAHP and the Tribes in advance of ground disturbing activities
on the subject parcels. The recommendations provided by HRA in the future
archaeological reports shall be followed during all soil disturbing activities.
h. The District shall obtain a DAHP Archaeological Site Alteration and Excavation
Permit for impacts to precontact sites and any NRHP-eligible or potentially eligible
historic period sites. No potentially ground disturbing activities are allowed in these
areas, including staging materials, parking vehicles, or using site areas to access other
work locations, until a DAHP permit is acquired. The DAHP Permit shall determine
the mitigation measures required for impacts to archaeological resources, which are
anticipated to include multiple opportunities to highlight the history and past land use
on the property and in Renton more broadly.
i. Comments and mitigation requests provided by the Tribes and/or DAHP during the
required DAHP permit application review, or review of the archaeological studies
shall be addressed. These may be documented in a memorandum of understanding

13. The following transportation measures have been incorporated into the project for
implementation during construction and prior to school opening.
a. Roadway Network: Frontage Improvements - The City will require frontage
improvements along five adjacent streets as follows:
i. S 2nd St – The project will only provide a dedication for future S 2nd St
improvements that will be made by the City as part of its planned future
roadway improvements in that segment. A waiver will be completed to
exempt the school project from S 2nd St improvements. On-site and north of S
2nd St, the project will provide walkway connections between the automobile
load/unload loop and the school buildings within the site.
ii. Airport Way – A new 8-foot-wide planting strip will be provided adjacent to
the back of the existing curb. The project will construct an 8-foot-wide
sidewalk adjacent to the planting strip.
iii. Shattuck Ave S – New curb and gutter will be installed 15 feet from the
roadway centerline. An 8-foot-wide planting strip will be provided adjacent to
the back of the new curb and a new 5-foot-wide sidewalk will be constructed
adjacent to the planting strip.
iv. S Tobin St–An 8-foot-wide planting strip will be provided adjacent to the
back of the existing curb. The project will construct a new 5-foot-wide
sidewalk adjacent to the planting strip.
v. Lake Ave S – An 8-foot-wide planting strip will be provided adjacent to the
back of the existing curb. The project will construct a new 5-foot-wide
sidewalk adjacent to the planting strip.
vi. Logan Ave S – The existing roadway pavement 20-feet from roadway
centerline will remain. A new 14-foot-wide roadway pavement section will be
constructed with a new 8-foot-wide school-bus load/unload and parking area.
New curb and gutter will be constructed with a new 12-foot-wide sidewalk
and street trees within grates.
b. Roadway Network: Off-Site Improvements - In addition to the required frontage
improvements, the project will make off-site improvements at several locations as
follows:
i. S 2nd St / Logan Ave S Intersection –The project will install two new curb ramps
and a new curb-bulb at the northwest corner; two new curb ramps at the northeast
corner; ramps at the southeast corner with APS buttons, and a single curb ramp at
the southwest corner.

bulbs on both sides of Logan Ave S north and south of the S Tobin St
intersection. It will also construct north/south curb ramps for the crosswalk on the
east leg and east/west curb ramps for a new crosswalk on the south leg. The west
leg of the intersection will be constructed as a new school site driveway. The
project will install an RRFB or half-signal at the new crosswalk on the south leg
the intersection for pedestrian crossings between the school and the east side of
Logan Ave S.
iii. Airport Way / Logan Ave S Intersection – The project will construct a new curb
ramp and a curb-bulb at the southwest corner of the intersection. The other
elements of the intersection will remain unchanged.
iv. Airport Way / Shattuck Ave S Intersection – The project will construct a new
curb ramp and curb-bulb at the southeast corner of the intersection. The other
corners of the intersections will remain unchanged.
v. S Tobin St / Shattuck Ave S Intersection – The project will construct two curb
ramps (one for north-south crossings, and one for east-west crossings) and new
curb-bulbs at the northwest corner of the intersection. It will construct a curb
ramp and new driveway entrance into the site on the east side of the intersection.
A curb ramp will also be constructed at the southwest corner.
vi. S 2nd St/ Lake Ave S Intersection – The project will construct a curb ramp at the
northeast corner of the intersection to serve crossings of S 2nd Ave to the south.
The southwest, southeast, and northwest corner will remain unchanged.
c. Roadway Network: Roadway and Curb Signage - Due to the school site
expansion, the District will coordinate with the City to confirm the new equipment
required as well as the locations and enforcement times for school-zone signage and
flashing beacons, especially at and around the expanded portions of the campus. The
District will also coordinate with the City on signage and restrictions for the school-
bus load zone proposed along the west side of Logan Ave S between Airport Way
and S 2nd St.
d. Operational Measures: Short-Term Conditions – Construction Management
Plan (CMP) – The District will continue working with the selected contractor to
refine the CMP that addresses traffic and pedestrian access control during school
construction for each major phase. It will confirm truck routes, lane closures,
walkway routes and closures, and parking disruptions, as necessary. The CMP may
also include measures to keep adjacent streets clean on a daily basis at the truck exit
points (such as street sweeping or on-site truck wheel cleaning) to reduce tracking
dirt off site. The CMP will identify parking locations for the construction personnel,
students, staff, and load/unload areas for school buses and passenger vehicles during
peak arrival and dismissal periods. It will also include measures to minimize or avoid
truck access/egress and deliveries during school peak arrival and dismissal periods.

AND CONSTRUCTION
During phases when on-site parking is limited, outside user-group events at the Ikea
Performing Arts Center (IPAC) may need to be limited or restricted. Those events
may occur if off-site parking can be arranged such as through a shared-parking
agreement with the City Center Parking Garage.
e. Operational Measures: Long-Term Conditions – Operations
i. Transportation Management Plan (TMP) – Prior to the school opening, the
District and school principal will establish a Transportation Management Plan
(TMP) to educate families about the access load/unload procedures for the site
layout. It will encourage school bus ridership, use of public transit, carpooling,
and walking or biking. The plan will define clear procedures and travel routes for
family vehicles and instruct family drivers not to block or partially block travel
lanes with queued or waiting vehicles. The plan will also address evening event
conditions by identifying appropriate parking locations for attendees, and or
adjusting the schedule or size of events to better accommodate demand with the
available parking supply.
ii. Event Parking Management – It is recommended that the school monitor
concurrent scheduling of the IPAC, black box theater, and other assembly spaces
(such as the gymnasium during varsity basketball games) to determine if parking
demand could exceed the on-site supply and to determine if management
measures may be required. Options for parking management during multiple
concurrent events may include directing attendees to off-site parking (such as the
City Center Parking Garage at the southeast corner of the S 2nd St / Logan Ave S
intersection about 500 feet from the school site).
