Please do your part in helping to protect our waterways. Report any spill, illicit discharges or illicit connections to our waterways or storm system by calling the City’s Spill Hotline. The city's staff understands the need for confidentiality, so calls can be anonymous. However, please provide as much detail as possible about the spill or illegal activity, including the date, time, location, a description of the spill or illegal activity and a description of the pollutant.
All City storm drains flow into waterways with no water quality treatment. So it is very important to report illegal dumping or even accidental spills in our roadways, storm systems or waterways.
Our actions within our watershed have a direct impact on our lakes, rivers, streams and wetlands. Please do your part in keeping our waterways healthy by helping us keep an eye out for illegal activity which can damage water quality.
