LOCATION WHERE APPLICATION
MAY BE REVIEWED:
Applicant documents are available online through the City of Renton
Document Center website. See also https://tin.al/AE4DV
The applicant is requesting State Environmental Policy Act (SEPA) review and a Shoreline Substantial Development Permit
(SSDP) for the Kennydale Lakeline Sewer System Replacement Project. The project site includes multiple parcels (noted
above), City of Renton right-of-way, King County Parks property, and private property located between 3905 Lake Washington
Blvd N and the north end of Gene Coulon Memorial Beach Park. The existing 4,680 -foot (4,680’) in-lake sewer system will be
replaced with a new land-based low-pressure sewer system serving 56 properties and a public park. The proposed
replacement system includes approximately 4,950 linear feet (4,950’) of new force main, 55 individual grinder pump stations,
and associated electrical and utility improvements, to be constructed primarily within Mountain View Ave N and an unnamed
access road east of the lake. The project will occur in two (2) phases: (1) upland construction of the new sewer system and (2)
in-water decommissioning of the existing lake -line system. In-water work will be staged from barges and occur during the
approved fish window (approximately July 16 to December 31). Temporary construction-related disturbance will total
approximately 113,670 square feet in upland areas and 875 square feet in aquatic areas. Work would occur within and
adjacent to Lake Washington, a Shoreline of the State. Shoreline designations on the site include Single -Family Residential,
Urban Conservancy, and Aquatic. Work is anticipated to start in early 2026 and last up to 18 months. The project includes
mitigation and restoration measures to ensure no net loss of shoreline ecological function. Supporting documents submitted
with the application includes a SEPA Checklist, Vegetation Management Plan, Geotechnical Engineering Report, Arborist
Report, and Lake Study.
Appeals of the environmental determination must be filed in writing on or before 5:00 p.m. on October 7,
2025. Appeals must be submitted electronically to the City Clerk at cityclerk@rentonwa.gov or delivered to City
Hall 1st floor Lobby Hub Monday through Friday. 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. The appeal submitted in person may be
paid on the first floor in our Finance Department. 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, an appeal public hearing will be set and all
parties of record will be duly notified in accordance with RCW 43.21C.110 and WAC 197-11-535.
