Commercial Fee Information & Credits

Stormwater credits are only available to Commercial Units.

Public Works and Engineering has developed a system of credit adjustments or reductions to the monthly stormwater utility fee for commercial units with the intent to encourage sound technical design practices through specific and approved actions which reduce the negative impact of development on the City’s stormwater system. Detailed information concerning stormwater credits is available in the City of Alcoa Stormwater Utility Manual (PDF).
