Description of Proposal: Renton School District (RSD) is proposing to integrate two vacant
parcels into the larger Transportation Center Facility. The parcels were purchased by the district
in 2017 to increase the parking and fleet storage capacity of the Center. The site on which the
work is to occur is a total of 19,596 square feet (0.44 acres). A small amount of work is proposed
on the large parcel associated with the Transportation Center, for a total disturbed area of 20,964
SF. The proposal is for 44 new surface parking spaces for employee parking, some of which will
be EV-ready. Parking lot lighting will be added for safety. Security fencing will be added along
the west, north and east perimeter and integrated to the existing fencing to create improved
security for the fleet vehicles. The location of the fencing will require a setback variance.
Approximately 5,743 square feet of landscaping and 16 new trees will be added, including an
approximately 10.5 foot landscaping strip along Park Ave N. and an approximately 15 foot strip
along N. Fifth St. Three significant trees will be removed due to construction. One driveway and
curb cut on the north side of the site along N. Fifth Street, and two driveways along Park Ave N.
will be removed and replaced with new sidewalk. The proposal includes a new approximately
1,200 square foot public amenity space on the northwest corner of the site.
Location of Proposal: 444 and 450 Park Ave N., Renton, WA 98057; King Co. Parcel Nos.
7224000676 and 7224000675.
Public and Agency Comments: This SEPA Threshold Determination is based on the public
record, including comments from agencies, tribes, property owners, and other interested parties
via mailings, publications and postings conducted by RSD. RSD issued notice of the SEPA
Checklist for comment on October 7, 2024 requesting the submittal of comments by October 21,
2024. Comments were received from the Duwamish Tribe. They have been integrated into the
findings and mitigation measures.

CAPITAL PLANNING
AND CONSTRUCTION
FINDINGS OF FACT:
1. Earth - The site where work will occur is approximately 20,964 and flat with less than 5% grade.
This proposal will add 6,801 SF additional impervious surfaces with new concrete and asphalt for
parking surfaces and pedestrian pathways. Total excavation proposed is 39 CY, total earthwork
proposed is 401 CY. A Geotechnical Report has been prepared. The recommendations within the
Geotechnical Report shall be followed.
2. Air – Best Management Practices will be employed to minimize dust-related emissions during
construction. After construction, no additional emissions to air are anticipated to result from the
proposal.
3. Water – There are no surface water bodies on the site. Stormwater design is based on the
requirements of the 2022 City of Renton Water Design Manual. Best Management practices will
be implemented. Stormwater will be routed to existing system and patterns. Four catch basins
will be removed as part of this proposal.
4. Plants – Three significant trees and approximately 7,128 SF of grass are proposed to be removed
for this work due to construction. Eight significant trees will be preserved. 16 new trees are
proposed to be planted internally and in a landscape strip, along with 12 other species of shrubs,
grasses and groundcover that are native to the area.
5. Environmental Health – There are no known hazardous chemicals or conditions that are
predicted to affect this proposal, beyond the removal and installation of paving materials.
6. Noise – Temporary, short term noise impacts will occur typical of construction activity.
Construction is anticipated to occur during the summer months of 2025 and between the hours of
7:00 am and 5:00 pm.
7. Land and Shoreline Use – The current use of the site is as vacant commercial. The larger
Transportation Center site is zoned as Light Industrial and used for fleet vehicle storage and
maintenance. Adjacent uses are a mix of residential, small-scale commercial, office, educational
and light industrial. there is an elementary school to the south and an older single family
residential area on the west side of the site. The use will not change as a result of the proposal,
nor will the proposal increase impacts to nearby or adjacent properties. The site is not within a
critical area or the vicinity of a shoreline of the state. No increase in staffing is anticipated.
8. Aesthetics – This proposal includes new parking lot lighting 25 feet in height. Streetscaping and
a public amenity space on the corner of N. Fifth St and Park Ave. N will improve the urban
design aesthetics.
9. Light and Glare – No safety hazards or light or glare impacts are anticipated from the proposed
lighting. The lighting has been carefully designed to reduce lightspill to adjacent neighborhoods.
Full cutoff-type luminaires will be used to direct light downward
10. Historic and cultural preservation –The site is modeled as being of high risk for discovery of
artifacts. There was a Cultural Resources Assessment conducted by Drayton Archaeology,
which did not recommend any archaeological management or mitigation measures, but did
acknowledge that the site is located in an area of moderate probability for encountering cultural
resources. There will be an inadvertent discovery plan in place during construction and the
Duwamish Tribe will be invited to observe construction.
11. Transportation – No change in access or employment levels are expected as a result of this
proposal, therefore no increase in traffic is predicted.
