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 storm water, SD1 charges a storm water service fee to any such property within our service area boundary. Areas that don’t have storm sewer pipes still benefit from SD1’s storm water services. For example, SD1 regulates what goes down public storm water pipes to keep pollution out of the streams that customers rely on for drinking water and recreation. The storm water fee supports this work.
