City of Tukwila <br />Public Works Department - Robin Tischmak, Acting Director <br />Allan Ekberg, Mayor <br />INFORMATIONAL MEMORANDUM <br />TO: Transportation and Infrastructure Committee <br />FROM: Robin Tischmak, Acting Public Works Director <br />BY: Greg Villanueva, NPDES Coordinator <br />CC: Mayor Allan Ekberg <br />DATE: November 9, 2017 <br />SUBJECT: NPDES Program (National Pollutant Discharge Elimination System) <br />Project No. 99341210 <br />2017 Surface Water Management Program Survey and Assessment <br />ISSUE <br />Review results of the 2017 Surface Water Management Program Survey and Assessment. <br />BACKGROUND <br />The City's National Pollutant Discharge Elimination System (NPDES) Phase II general permit requires <br />that the City measure its citizen's stormwater knowledge and behavior. The City's Stormwater <br />Management Program (SWMP) has been meeting this requirement by conducting a series of <br />stormwater survey and assessments. The outcome of the survey and assessment is used to guide the <br />City's education and outreach program. <br />ANALYSIS <br />The City hired HR2 Research/Analytics (formerly Hebert Research) to conduct our 2017 phone survey <br />and assessment. The total number surveyed in 2017 was 50 businesses and 250 residential in which <br />the results were compared with previous years, 2011, 2012, 2013, and 2015. <br />The main differences for 2017 results were: <br />• Priority 1 issues include topics such as Low Impact Development, pesticides, fertilizers and <br />herbicides. Correct answers were less than 50%. <br />• Priority 2 issues include washing cars at home, disposal of latex paint, definition of an illicit <br />discharge. Between 50 to 80% gave correct answers. <br />• Priority 3 issues include topics such as having your oil changed by an auto shop rather than at <br />home and the price of protecting our water ways from pollutants versus the cost of cleaning <br />contaminated water. Over 80% gave correct answers. <br />Nest step is education and outreach on Priority 1 issues. <br />FISCAL IMPACT <br />The cost to provide the stormwater survey and assessment was $10,886.25. <br />RECOMMENDATION <br />Information only. <br />Attachment: 2017 Stormwater Research Findings <br />\\PWStore\PW Common$\PW Eng\PROJECTS\A- DR Projects\NPDES Program (99341210)\SWMPEdOutreach\Survey 2017\InfoMemo2017StormwaterSurveyResults.docx <br />21 <br />
