Stormwater Utility
Adams County Stormwater Utility (SWU) was established in 2012. The SWU assesses an annual user fee to all properties located within the service area. The stormwater utility is an independent funding mechanism to pay for the cost of services related to the implementation of the Stormwater Management Program.

The SWU service area encompasses properties within unincorporated Adams County. This area is bordered on the north, south and west by the County boundary. The eastern boundary of the service area is bordered by Schumaker Road (near Denver International Airport). This area excludes any properties within the city limits of the following municipalities: Aurora, Northglenn, Thornton, Commerce City, Brighton, Westminster, Federal Heights, Arvada, Bennett and Lochbuie.

The Stormwater Utility, currently provides public drainage services for approximately 27,000 properties and extends approximately 257 square miles (164,480 acres).

How is the fee determined?
Typical Single Family Home Example:
Step 1:
 Calculate the total square feet of impervious area
     
           1,100 sq ft (roof)
        +    750 sq ft (driveway) 
        +    300 sq ft (patio)
        +    100 sq ft (sidewalk)
    _______________________
           2,250 sq ft total impervious area

Step 2: Calculate the corresponding SWU fee: the total square footage of impervious surface is multiplied by the rate ($0.02004/sq ft)
       
         2,250 sq ft × $0.02004/sq ft = $45.09/year

Step 3: Compare the calculated SWU fee with the annual cap fee for your property type. The amount you pay is the lesser of the two. 
Note: The calculation above does not apply for multi-family properties such as apartment complexes, or condominiums. In this case, the SWU fee calculated in step 2 is divided by the total number of existing units.
