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).
