Stormwater Utility Credit Program

The Stormwater Utility disputes & appeals process is now open through Monday, June 30.

The credit application period is closed and will re-open Nov. 1, 2025, through Jan. 31, 2026. If you take certain actions throughout the 2025 calendar year to reduce stormwater runoff on your property, you can apply for credit to offset a percentage of your Stormwater Utility bill in 2026. Voluntary credit applications must be submitted through Request Service/Report a Problem during the application period.

*Note: The amount of voluntary credit that can be earned is capped at 35% per property.

Approved credits will be applied to the following year’s real property tax bill, split equally between the first and second bill.

There are two types of credits available: voluntary and mandatory.

Voluntary credits are elective actions that property owners can choose to take to reduce stormwater runoff or improve the environment.

Mandatory credits are automatically given if you were required to install stormwater facilities as a condition of construction or redevelopment and you remain in compliance with the required inspections. If mandatory stormwater facilities are installed on your property, you should have received a letter with more information on how to qualify for mandatory stormwater credits.

View the Credit Manual in English or Spanish for more details on credit guidelines for each type of credit, submission requirements, tips for success, and more.
