City of Tukwila <br />Allan Ekberg, Mayor <br />TO: Transportation & Infrastructure Committee <br />FROM: Bob Giberson, Public Works Director,�W__ _J <br />BY: Mike Perfetti, Habitat Project Manager <br />CC: Mayor Ekberg <br />DATE: June 23, 2017 <br />SUBJECT: Storm Water Quality Retrofit Project <br />Project No. 91241202 <br />Waterworks Grant Application <br />ISSUE <br />Authorize the submittal of a grant application to the King County Flood Control District, through their Waterworks grant <br />program, to fund water quality testing at Tukwila's 'Big 3' creeks — Riverton, Southgate, and Gilliam. <br />King County is currently seeking applications for its Waterworks Program for the 2017 cycle. The Waterworks grant has <br />switched from an annual to a two-year cycle and $1,860,000 is available for this grant cycle. Grant amounts are between <br />$20,000 and $250,000 and a 10% City match is required. City staff recently submitted a letter of intent and if invited to <br />submit a full application, the City will need to submit an application by September 13, 2017. Awarded projects are able to <br />begin in the summer of 2018. <br />DISCUSSION <br />Recent experience with the Salmon Recovery Funding Board (SRFB) review panel has brought to light their hesitancy to <br />fund salmon recovery projects where there is a perception that the project will expose salmon to dangerous levels of <br />polluted stormwater. Currently, there are two fish barrier removal projects in the 2017 CIP that are intended to give rearing <br />(and potentially spawning) access to creeks within the City (Riverton and Gilliam Creeks). While the Riverton Creek <br />Flapgate Removal Project has received some SRFB funding, and is being considered by them for further funding, the <br />reviewers continue to express concern about the quality of habitat that is being provided due to stormwater contributions <br />into these creek systems. <br />The King County Flood Control District's Waterwork grant will be used to collect and analyze one - years' worth of data at <br />three locations within each creek (9 locations total). The goal of this study is to identify water quality deficiencies to target <br />treatment projects in the future, which will improve overall water quality, and leverage the City's ability to acquire salmon <br />restoration grant funds for future projects in those creeks. <br />FINANCIAL IMPACT <br />If the City is awarded its grant request, the 10% City matching requirement would be $9,500. These funds would be used <br />primarily to support City staff in project management and will be drawn from the Storm Water Quality Retrofit Program (p 97, <br />2017 CIP). The requested grant funds would be used to retain a water quality science firm. <br />RECOMMENDATION <br />Transportation & Infrastructure Committee approval to submit a grant application to King County for its Waterworks Program <br />for the 2017 cycle. <br />Attachment: 2017 CIP Pg. 97 <br />\\PWStoreTW Common$\PW Eng\PROJECTS\A- DR Projects\Storm Water Quality Retrofit (91241202)\Info Memo Waterworks Grant 06272017.docx <br />
