Stormwater Utility Credit Program

The credit program application period is currently closed. If you take certain actions to reduce stormwater runoff on your property, you can apply for credit Nov. 1 through Jan. 15 to offset up to 35% of your utility bill in 2025.

Approved credits will be applied for one full calendar year from the date of approved application, split equally between the first and second half real property tax bills during the calendar year.

What are Voluntary Credits?

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.
