DESCRIPTION
Pierce County completed a Levee Setback Feasibility Study for portions of the Puyallup, Carbon and White Rivers in Pierce County--a high priority need in the Lead Entity Strategy.This study evaluates the feasibility of 32 setback projects that will reestablish dynamic channel forming process and recapture lost flood storage. The study also assesses which levee setback projects are best suited to restoring salmon habitat and salmon recovery.The study picked project locations where features such as historic side-channels and hydrology indicate the likelihood that given the opportunity, natural processes will act to create the desired habitat. Engineering concerns, land-use, hydrology and flood protection, cost, and landowner willingness were evaluated along with habitat restoration for project prioritization. A Prioritization Workbook and Site Catalogue were developed to assist in assessing the feasibility of levee setback at the 32 sites using the adopted criteria. The Prioritization Workbook criteria included: Project Costs and Land Availability with the following goals: Goal 1 – Increase floodplain connectivity and flood storage Goal 2 – Reestablish short and long-term geomorphic processes and function Goal 3 – Maximize aquatic habitat diversity and use  SEE DESCRIPTION BELOW FOR LINKS TO DOCUMENTS:

GOAL
The project management team will work with a technical advisory group (TAG) and a consultant team to comprehensively identify and prioritize levee setback/floodplain reconnection projects. The TAG will develop the prioritization tools and will likely consider potential for natural process restoration, relative benefit for salmonids, land use and landowner willingness, engineering constraints and challenges, and relative cost. Potential project sponsors will then be able to focus on implementing specific projects – by acquiring property, completing designs, obtaining funds, etc. The proposed project will include preliminary design of a few high priority projects from the catalog of potential projects. A technical advisory group has been established with representatives from NOAA Fisheries, the Puyallup and Muckleshoot Tribes, and King and Pierce Counties.
