This DNS-M is issued after using the optional DNS process in WAC 197-11-355. There is no further comment period. DATE OF NOTICE OF ENVIRONMENTAL DETERMINATION: January 10, 2022 PROJECT NAME/NUMBER: PR21-000314 600 SW 10th St Parking Lot Upgrades LUA21-000273, ECF, SA-A PROJECT LOCATION: 600 SW 10th St (PID 2146000050) APPLICANT/PROJECT CONTACT PERSON: Sky McClave, Kimley-Horn, 1000 2nd Ave, Suite 3900, Seattle, WA 98104 / sky.mclave@kimley-horn.com LOCATION WHERE APPLICATION MAY BE REVIEWED: Applicant documents are available online through the City of Renton Document Center website. See also https://cutt.ly/2QDN7xf 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 manufacturing 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. Appeals of the environmental determination must be filed in writing on or before 5:00 p.m. on January 24, 2022. Appeals to the Examiner are governed by RMC 4-8-110 and more information regarding the appeal process may be obtained from the Renton City Clerk’s Office, (425) 430-6510. Due to the ongoing state of emergency enacted by Governor’s Proclamation 20-05, the City Clerk’s Office is working remotely. For that reason, appeals must be submitted electronically to the City Clerk at cityclerk@rentonwa.gov or delivered to City Hall 1st floor Lobby Hub only on Tuesdays and/or Wednesdays. The appeal fee, normally due at the time an appeal is submitted, will be collected at a future date if your appeal is submitted electronically. Appeals to the Hearing Examiner are governed by RMC 4-8-110 and additional information regarding the appeal process may be obtained from the City Clerk’s Office, cityclerk@rentonwa.gov. PUBLIC HEARING: If the Environmental Determination is appealed, a public hearing will be set and all parties notified.
