DESCRIPTION
The City of Kent has completed final design and permitting of the Downey Farmstead Restoration project which will realign and setback Frager Road from the Green River, to reconnect the floodplain and create off-channel rearing and refuge habitat, primarily for juvenile Chinook salmon. A secondary goal of the project will create additional flood storage to help alleviate flood damage to nearby urban and agricultural areas.
The project site is located in King County along the left (south) bank of the Green River between river mile 21.5 and 22.3 on 21.8 acres of property owned by City of Kent and purchased with 2002 SRFB funding (02-1601). The downstream edge of the site coincides with the confluence of Mullen Slough with the Green River.
In addition to completion of the final design plans, the following was completed: specifications; final design report (including hydraulic analysis, scour analysis, geotechnical analysis, large wood structural stability analysis and pile analysis); construction quantities and cost estimate; contract bidding documents and general contract conditions; Cultural Resources Inventory Report; Wetland and Stream Report; Draft Maintenance and Adaptive Management Plan; and permit submittals.
