The City's Stormwater Drainage System Utility is modeled after the Stormwater User Fee Study adopted by City Council on April 25, 2022. This study used a combination of aerial images and Geographic Information System (GIS) technology to measure the amount of Impervious Surface Area (ISA) present on a randomly selected sample of 150 single family residential properties within the City. Based on the data from this sample, the average amount of ISA on single family residential parcels was determined to be approximately 4,500 square feet. The City is using this measurement as the basis for the billing unit of the Stormwater Drainage System Services user fee (also known as the "Equivalent Residential Unit (ERU)").
User fee billed to Residential properties, per month:
*For Single Family Residence only. All other Residential Property monthly fees are further defined in the Stormwater Drainage System Utility Fee Structure & Credit Policy (PDF).
User fee billed to Commercial properties, per month:

*The total Impervious Surface Area (ISA) determines the number of Equivalent Residential Units (ERUs) billed per month. Commercial Property monthly fees are further defined in the Stormwater Drainage System Utility Fee Structure & Credit Policy (PDF).
