NON-SIGNIFICANCE - MITIGATED (DNS-M)
Project File Numbers: PR21-000314 / LUA21-000273, ECF, SA-A
Project Name: 600 SW 10th St Parking Lot Upgrades
Applicant: Sky McClave, Kimley-Horn, 1000 2nd Ave, Suite 3900, Seattle, WA 98104
Project Location: 600 SW 10th St (PID 2146000050)
Project Description: The applicant is requesting Environmental (SEPA) Review and Administrative Site Plan
Review to construct an asphalt surface parking lot north of the existing industrial building
located at 600 SW 10th St (APN 2146000050). The building is currently occupied by a
metal supplier and contains both warehousing and office space. The 10.01-acre site has
a zoning designation of Medium Industrial (IM) and has a Comprehensive Plan future
land use designation of Employment Area (EA). The site is currently occupied by a metal
supplier with warehousing and office space in an existing 114,531 sq. ft. masonry
structure. The proposed surface parking lot would consist of 137 parking stalls in four (4)
rows of 90-degree stalls with two (2) drive aisles and the associated perimeter and
interior parking lot landscaping. According to the applicant, the proposed paved parking
area is intended to replace the existing gravel parking area currently used for parking of
WB-40 truck trailers and would not result in a change of use or additional traffic trips.
The project proposes using an underground detention vault for flow control a modular
wetland for water quality. Access to the parking area would remain via the three (3)
existing curb cuts on SW 10th St. Access to the north onto to Seneca Ave SW would
remain gated and provide emergency access only. According to COR Maps, a High
Seismic Hazard is mapped on the project site. No trees are proposed for removal. The
project would result in approximately 146,183 sq. ft. of new or replaced impervious
surface. The applicant submitted an Environmental Checklist, Geotechnical Report,
Drainage Report, and Traffic Memo with the application.
