Stormwater Utility Fee

Beginning January 1, 2022, a stormwater utility fee will be collected to provide a dedicated funding source for stormwater programs and management. The fee will appear in the monthly utility bill for both residential and non-residential customers, and is based on the amount of impervious surface on your property because:

  1. Impervious surfaces don't absorb rain/melting snow in the ground, resulting in the need to manage where that water goes and how it flows.
  2. The more impervious surface, the more stormwater we have to manage. 

The stormwater program was previously funded by property taxes, but now will be funded by collection of this fee to provide an equitable way for customers to contribute to the fund since the monthly fee is based on impervious surface instead of property value.

What is stormwater?

  • Stormwater is water from rain or snow that does not absorb into the ground. When not absorbed into the ground, stormwater moves to our streams and rivers and can carry pollutants.

Stormwater Fee Rates - Based on Impervious Surface

An Impervious Surface is a hard surface on a property that does not allow rain to soak into the ground such as, but not limited to, rooftops, carports, driveways, garages, sidewalks, storage sheds, parking lots, and patios.

There will be a separate fee rate for residential and non-residential customers. Monthly rates are still being determined and are calculated with the use of a geographic information system (GIS) and aerial imagery, this method provides an equitable fee structure for all utility customers.

  • Residential monthly fee - based on the total amount of square-feet of impervious surface on our property (not just your home's square-footage).
  • Nonresidential monthly fee - based on an Equivalent Residential Unit (ERU) and is for all developed non-residential property such as commercial, office/institutional, churches, apartment complexes, etc.
