Stormwater Utility Rates

Stormwater fees are dedicated to the repair, replacement and construction of systems to manage stormwater runoff from public streets and private properties.

The stormwater portion of your utility bill is one fixed, monthly charge of $17.80 per Drainage Residential Unit (DRU). Effective Jan. 1, 2025, the charge increases to $19.48 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. 

Flood Safety District Pass-Thru fee 

New: Flood Safety District Pass-Thru fee begins effective May 8, 2025. The monthly charge is $2.00 times the DRU and funds the Urban Flood Safety and Water Quality District. This non-City organization was created by the Oregon State Legislature to upgrade and maintain the Columbia River levee system. For the average residential customer this pass thru fee will equate to $2.00 per month; properties with larger impervious surface will see a higher charge. For additional information about the District, please call 503-281-5675 or visit Urban Flood Safety and Water Quality Districtfor more information.
