Any property with a roof, driveway or other impervious surface can contribute to storm water issues, including flooding, erosion and poor water quality. In order to effectively manage stormwater, SD1 charges a stormwater service fee to any such property within our service area boundary. Areas that don’t have storm sewer pipes still benefit from SD1’s stormwater services. For example, SD1 regulates what goes down public stormwater pipes to keep pollution out of the streams that customers rely on for drinking water and recreation. The stormwater fee supports this work.
