Stormwater Utility Credit Program

The application period for the Stormwater Utility credit program is officially open now through Feb. 28, 2025. The County Board approved additional enhancements to the credit program at the December Board meeting. The presentation and Board report are available here.

The credit program application period is open! If you take certain actions throughout the calendar year to reduce stormwater runoff on your property, you can apply for credit Dec. 16 through Feb. 28 to offset up to 35% of your Stormwater Utility bill in 2025. Voluntary credit applications must be submitted through Request Service/Report a Problem.

Approved credits will be applied to the following year’s real property tax bill, split equally between the first and second bill. Voluntary credit activities may be completed anytime from Jan. 1, 2024 - Dec. 31, 2024, for credit on your 2025 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.
