Hari Ponnekanti, Director/City Engineer INFORMATIONAL MEMORANDUM TO: Transportation and Infrastructure Services Committee FROM: Hari Ponnekanti, Public Works Director/ City Engineer BY: Brittany Robinson, Public Works Grant Analyst Josh Hopkins, Project Manager CC: Mayor Ekberg DATE: February 3, 2023 SUBJECT: Surface Water Fund — Nelsen Side Channel Project No. 91641203 Grant Application ISSUE Authorize the submittal of a grant application to the King County Conservation Futures (CFT) grant program. BACKGROUND The Nelsen side channel is a remnant section of the Green River as it existed prior to the construction of the 1-405 in the 1960s. The remnant channel is separated from the mainstem of the river by a constructed levee but offers potential as off - channel rearing habitat for threatened Puget Sound Chinook salmon and other aquatic species. This project will set the levee back to create a ±1.2 -acre side channel, restore an acre of riparian forest, provide additional flood storage, and provide public access to the river. Currently, there is a concept design in place for this project and property transfer arrangements are underway between the City, WDNR and WSDOT. DISCUSSION King County is currently seeking applications for its CFT grant program. The CFT program goal is to deliver projects that protect forests, shorelines, farms, greenways, and trails for future generations to enjoy forever. Grant submissions are due on March 6, 2023. FISCAL IMPACT The City is seeking $200,000 from the CFT grant program to fund acquisition costs of the Nelson Family Trust property (shown on the attached map) for the Nelsen Side Channel Project. The grant application indicates that the City must match the grant 1:1. The match would come from the Surface Water utility fund and the Open Spaces River Corridor grant, which has $25,000 allocated for acquisition. Staff are also applying for a match waiver, and if approved, the CFT grant would fund the project 100%. Amount Fund Source 2023-2024 Match Budaet CFT Grant $200,000 OSRC $25,000 Match 200.000 Utility Fund 200,000 Total $400,000 $250,000 RECOMMENDATION Committee is being asked to approve the submittal of the Conservation Futures grant application for the Nelsen Side Channel project.
