Stormwater Utility Rates

Stormwater fees are dedicated to the repair, replacement and construction of systems to manage stormwater runoff.

The stormwater portion of your utility bill is one fixed, monthly charge of $16.26 per Drainage Residential Unit (DRU). Effective Jan. 1, 2024, the charge increases to $17.80 per DRU.

Each DRU equals 2,500 square feet of impervious surface (rooftops, driveways, paved walkways and patios). 

Single-family residential homes are set at one DRU for billing purposes but may be adjusted up or down to match actual on-property impervious surface measurements if requested by the customer. 

Stormwater fee discounts

Homeowners, who meet stormwater reduction requirements, may reduce the stormwater utility bill amount.
