Project Location: 505 S 4th St, Renton, WA 98057 (APNs 7839800145 and 7839800190)
Project Summary: The applicant is requesting a Hearing Examiner Conditional Use Permit and
Environmental (SEPA) Review to operate a social service organization (West
African Community Center) on the project site. The project site is comprised of
two (2) parcels totaling approximately 17,140 square feet in area within the
Center Downtown (CD) zone, Urban Design District A, and Commercial and
Mixed-Use (CMU) Comprehensive Plan land use designation. The West African
Community Center is proposing to occupy an existing 11,465-square-foot, two-
story building that was previously occupied by a window coverings company for
retail operations, warehousing, manufacturing, and office space. The proposal
includes minor internal tenant improvements for office uses, a retail sundries
store, tutoring services, volunteer services, and community board meetings.
Access to the site is provided via an alley off S 4th St along the west boundary of
the project site to an existing surface parking lot located to the rear of the existing
building. According to COR Maps, a high seismic hazard area and wellhead
protection areas (zones 1 and 2) are mapped on the project site.

ENVIRONMENTAL REVIEW
In compliance with RCW 43.21C.240, the following environmental (SEPA) review addresses only those
project impacts that are not adequately addressed under existing development standards and environmental
regulations.
A. Environmental Threshold Recommendation
Based on analysis of probable impacts from the proposal, staff recommends that the Responsible
Officials:
Issue a DNS with a 14-day appeal period.
B. Mitigation Measures
1. None.

D. Environmental Impacts
The proposal was circulated and reviewed by various City Departments and Divisions to determine
whether 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: The project site is located within a high seismic hazard area. A Geotechnical Report was
not included with the land use application materials as no exterior improvements to the existing
building are proposed. The proposed project is limited to a change of use and interior tenant
improvements.

Staff Report to the Environmental Review Committee
LUA24-000390, CU-H, ECF
Report of October 13, 2025 Page 3 of 4
ERC_West_African_Community_Center_251013_Final
It is anticipated that the city’s adopted building code and construction standards would
adequately mitigate any impacts of the proposed tenant improvements on the project site;
therefore, no further mitigation is recommended.
Mitigation Measures: None recommended.
Nexus: Not applicable.
2. Historic and Cultural Preservation
Impacts: Staff received comments from the Duwamish Tribe (Exhibit 7) during the 14-day public
comment period. The Duwamish Tribe requested that any permanent lighting be dark sky
compliant to reduce light pollution. As the project proposal does not include any exterior
additions and is limited to a change of use with interior tenant improvements, it is not anticipated
that the proposal would include exterior light fixtures. Therefore, no further mitigation is
recommended.
Mitigation Measures: None recommended.
Nexus: Not applicable.
3. Transportation
Impacts: A Trip Generation Assessment, prepared by Heath & Associates, dated September 2,
2025 (Exhibit 5), was submitted with the project application materials. The project proposal was
subjected to the Transportation Concurrency Test (Exhibit 12). The proposed development is
anticipated to generate an increase of approximately 31 weekday daily trips. During the weekday
AM peak hour, the project would generate a decrease of 17 weekday AM peak hour trips (-13 in, -
4 out). During the weekday PM peak hour, the project would generate an increase of
approximately six (6) net new trips (1 in, 5 out). The proposed project passes the City of Renton
Traffic Concurrency Test. A Traffic Impact Analysis was not required to be submitted with the
application materials as the proposal would not generate 20 new AM or PM peak hour trips. The
proposal is not anticipated to result in new transportation impacts to the city’s transportation
system. Therefore, no further mitigation is recommended.
Mitigation Measures: None recommended.
Nexus: Not applicable.
4. Utilities
Impacts: Staff received comments from the King County Wastewater Treatment Division
(KCWTD) (Exhibit 9). The comments received from the Environmental Planner note that a capacity
charge is to be applied to any project that results in a new connection to the sewer system or any
change in use of a building that includes an increase in plumbing fixtures. King County requested
that their comments be provided to the sewer department to ensure that proper fees were
collected in the event that the work proposed falls within the scope of work noted above. These
comments were provided to the city’s Development Engineering Division for consideration.
Mitigation Measures: None recommended.
Nexus: Not applicable.
E. Comments of Reviewing Departments
The proposal has been circulated to City Department and Division Reviewers. Where applicable, their
comments have been incorporated into the text of this report and/or “Advisory Notes” to the applicant.
✓ Copies of all Review Comments are contained in the Official File and may be attached to
this report.
