The Stormwater Utility program is responsible for meeting all quality and quantity issues including the Town's Stormwater Management Plan, Floodplain and Erosion Hazard Management, and supporting all other Town programs that are impacted by storm events.  This program also coordinates with Federal, State and local government agencies related to the Town's Stormwater program.

Stormwater Mission
To provide safe and efficient management of the Stormwater Utility, to promote and protect life and safety, water quality, and the Town's working and natural environments before, during, and after the occurence of storm events in accordance with all Town codes, standards and policies.

Illicit Discharge Detection and Elimination
Federal regulations mandate that municipalities throughout the United States, implement an illicit discharge detection and elimination system. An illicit discharge is defined by the U.S. Environmental Protection Agency as, “any discharge to a municipal storm sewer system that is not composed entirely of stormwater.”

Examples of illicit discharges include oil, paint, yard waste, lawn chemicals, pet waste, commercial or industrial wash water, trash and sediment from construction sites. Click here to view the video, "Illicit Discharge - A Grate Concern," for examples of illicit discharges.

We need your help. If you suspect an illicit discharge or have any other Stormwater concern, please email or call 520-229-4816.

Stormwater Best Management Practices (BMPs)

  • Automotive Maintenance & Car Care BMP (PDF)
    Water runoff from streets, parking lots and driveways picks up oil, grease, asbestos, zinc and other metals and organic compounds from cars and spilled fuel. These chemicals eventually make their way into our storm drains, harming our environment. We greatly appreciate your continued assistance in preventing these hazards from entering the storm drain by following these Automotive Maintenance and Service Best Management Practices.
