Illicit Discharge Tracking Sheet

We invite all community members to participate in the 2015 Stormwater Survey. The Coalition will use the survey to gauge the public's knowledge of stormwater issues, including the impacts of urban run-off and other harmful discharges into local waterways.  Based on the survey responses, the Coalition will improve their regional stormwater pollution prevention education and outreach program.  Your input is invaluable and all responses are completely anonymous.  https://docs.google.com/forms/d/1ba3xZUMVQQQ0e8ALjjv-esC5ZQq0sekw3TmSbtiIde0/viewform?c=0&w=1.
