Consequently, the objectives of this habitat substitution project are to construct an off channel habitat that consists of Up to 1.5 acres of shallow -water mudflat at elevation 0 feet +5.6 ft. (NAVD 88). The majority of this will be excavated on the 2.16 acres of upland owned by the City of Tukwila with the balance to be created by re- grading river bottom owned by Washington State Department of Natural Resources. Approximately 0.5 acres of fringing, emergent marsh at elevation +5 6 ft. +9 ft. Approximately 0.8 acres of upland side slope at elevation +9 ft. Area figures are based on conceptual design calculations and subject to change during design The bias will be to focus on mudflat habitat, however, as that is the habitat structure thought to be most needed in the transition zone The Duwamish Gardens project helps implement priority WRIA 9 Salmon Habitat Plan: Makina Our Watershed Fit for a Kina project DUW -7 (page 7 -90) Thanks to in -kind services provided by the Washington Department of Fish Wildlife (WDFW), the conceptual design for this project was completed at no cost to the project proponent or local funders The conceptual design process explored two alternative layouts, different slopes, and calculated volumes of materials to excavate. This analysis, completed in early 2010, allowed the project team to identify a preferred layout. The WDFW analysis and conceptual plans are attached to this application. Not doing this project will forego the opportunity to create a meaningful (4 -5 increase in high quality mudflat habitat in the Duwamish. Moreover, because of its location in the heart of the transition zone, where the highest concentrations of juvenile outmigrants have been observed, the per square foot benefit of the project to juvenile salmonids should be relatively high Not doing the project would mean the watershed would not advance toward its estuary habitat creation objectives that are necessary to meeting the Viable Salmonid Population goals for WRIA 9 3.
