Close, Senior Planner PROPERTY OWNER: City of Renton, 1055 S Grady Way, Renton, WA 98057 APPLICANT/CONTACT: Awet Kassa, King County Wastewater Treatment Division | Environmental & Community Services Section, 201 S Jackson St KSC-NR- 5500, Seattle, WA 98104 PROJECT LOCATION: 550 Monster Road SW, Renton, WA 98057 PROJECT DESCRIPTION: The applicant, King County Wastewater Treatment Division (WTD), is requesting a Shoreline Exemption for emergency maintenance and repairs at the Black River Pump Station (BRPS), located at 550 Monster Rd SW, Renton, WA (APN’s 3779200090 and 7229500281) (see attached drawings). The BRPS is located on a concrete dam that spans the Black River channel, conveys all Springbrook Creek flow to the Green River, and is a critical component of the Green River flood control system. The BRPS has operated continually since it was constructed in 1972 and the pump station protects against signification flood damage that could occur if the Green River flood flows back up in the Black River. The repair project is in the Resource Conservation zone and is within the Black River/Springbrook Creek Shoreline Jurisdiction, Reach A (BRSC-A). The Black River is a Shoreline of the State and a Type S stream. Recent heavy rains made two (2) existing King County fish screens inoperable at the BRPS, which is a violation of local, state, and federal fish protection regulations. Due to the storm flows, the fish screens at the BRPS have become blinded with sediment and the inefficient screen cleaning system resulted in increased hydraulic force on the screens. This force caused two screens (6E and 6W) to bend and be permanently deflected. These issues pose a significant risk to the operation of the BRPS, both in terms of flood control operations as well as for fish protection, to keep fish from entering the pump bay. The hydraulic forces on the screens pose a risk of further damage occurring to the screens. The work to correct the current situation would require the following efforts: a. Expedited Fish Screen Replacement – Remove and replace the damaged screens with in-kind and available spare screens as soon as possible. b. Diving Services for Expedited Fish Screen Maintenance – Remove sediment upstream of the fish screens to help free the screens to be raised. c. Fish Screen Cleaning – Raise the “stuck” fish screens out of the channel so they can be cleaned.

The proposed project would not alter the current use of the facility or property. The proposed project does not include any fill or excavation, nor the removal of any trees, nor does it include any work that would exceed 35 feet above the average grade level or obstruct any views. The proposed work would occur as soon as permits are received or January 29, 2021, whichever occurs first. SEC-TWN-R: SW ¼ of Section 13, Township 23N, and Range 4E W.M.

The damaged fish screens and recent sediment build-up, due to a severe storm event, pose a significant risk to the operation of the BRPS, both in terms of flood control operations as well as for fish protection, and are a threat to public health, safety and the environment. The proposed development is: Consistent with the Shoreline Management Act. Not Applicable to the guidelines of the Department of Ecology where no Master Program has been finally approved or adapted by the Department. Consistent with the City of Renton Shoreline Master Program.
