Stormwater Retrofit Planning Project for WRIA 9

WHY ARE RETROFITS IMPORTANT?• Stormwater causes major damage

to streams

• Improve fish habitat

• Recover Puget Sound ecosystem

• Large portions of developed areas have no or inadequate controls

• Flow and water quality are important

PROJECT CONTACTJim SimmondsKing CountyJim.Simmonds@KingCounty.govP R O J E C T A R E A

• WRIA 9; Green-Duwamish Watershed and direct drainages to Puget Sound• Excluding headwaters upstream of Howard Hanson Dam (forested) and the City of Seattle (combined system)

PROJECT OBJECTIVES• To assess stormwater retrofit

needs

• To establish approaches that minimizes costs while meeting needs

• To develop prioritization approach

• To present plan to WRIA 9 Watershed Ecosystem Forum for consideration

• To extrapolate costs to rest of Puget Sound to establish sound-wide retrofit cost estimate
