The Riverton City Storm Water Utility was created in 2010 to fund cost necessary to satisfy Municipal Separate Storm Sewer System (MS4) Permit requirements set forth by The Federal Clean Water Act of 1972.  

The Federal Clean Water Act requires cities to protect streams, rivers, and lakes, in their jurisdictions, from polluted storm water.  Protecting water bodies require dedicated personnel, equipment, the development of programs and the continual management of these programs.  Municipal governments were left on their own to carry the cost of this mandate.

Many cities in Utah and across the nation have implemented Storm Water Utility Fee. Riverton City has also found it necessary to implement a monthly fee in order to meet the demands of the Utah Clean Water Act.

All properties impact the quality of water discharged to surface and groundwater systems and should be responsible for their own impact.  To equitably apply the stormwater fees, as much as possible, most MS4's base the fee on individual impact by calculating the amount of runoff generated on developed property.  Therefore properties who minimize their impact by reducing the amount runoff and reducing the pollutants that can reach water bodies through surface discharges and pollutants discharged into ground possibly reaching groundwater systems.  It should also be understood that responsibility is not only runoff generated on one's property but also property shared by communities such as public roads we all use to access our property.  Therefore property owner's who reduce their discharge to zero and prevent pollutants from reaching groundwater resources still have a shared community impact.

In Riverton City, residential, commercial, institutional and industrial properties all pay a stormwater utility fee.  MS4's in accordance to the relatively new Stormwater Industry usually bases the fee on what is called a Equivalent Residential Unit (ERU) which put simply is impervious area that generates runoff expected from residential properties in the MS4.  The runoff expected from these residential properties is estimated by measuring the impervious area of  a representative sample of residential property, densities, sizes and market types unique to that MS4.  All residential properties pay the same unit fee but commercial, institutional  and industrial prosperities all pay an amount based on the increase impact relative to the residential impact or ERU.   This is intended to facilitate a means for all properties to pay an amount relative to their own runoff and pollution impact.   

Below is information and applications for adjusting Stormwater Utility Fee amounts.
Common question regarding Stormwater Utility Fees.

  • Utility Fee Facts

Residential property owner's who feel their ability to pay the monthly fee is not possible based on their unique financial circumstances may apply for a fee reduction.

Commercial, institutional and industrial property owner's who feel their Stormwater Utility Fee is in error may apply for a stormwater utility fee amendment.

Also properties that desire to reduce their fee by reducing their runoff impact and contain pollutants by installing water quality devices and or improve their property with low impact development infrastructure may apply for a Stormwater Utility Fee reduction through the terms of the Utility Fee Adjustment Application which includes creating a Long-Term Stormwater Management Plan and entering into a maintenance Agreement, including but not limited to: building qualifying infrastructure, satisfying flood control and water quality performance levels and ensuring this infrastructure is maintain and continues to perform to its approved design levels.
