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

The MS4 Permit requires cities to protect streams, rivers, and lakes, in their jurisdictions, from polluted storm water.  Protecting water bodies require dedicated personnel, equipment and continual management of stormwater protection programs. 

Many cities in Utah and across the nation have implemented a Storm Water Utility Fee. Riverton City has also found it necessary to implement a utility fee in order to meet the demands of the MS4 Permit.  Property owners are welcome to request a copy of the permit and you can also find it by searching the web for "Utah MS4 Permit".

All properties impact the quality of water discharged to surface and groundwater systems. In addition, all property owners use the roadways for access to their property.  The roadway storm drain systems we all use must be drained and also managed to protect water resources. To equitably apply the stormwater fees, as much as possible, most MS4's base the fee on individual property runoff impacts.  Therefore property owners who generate a larger amount runoff and pollutants are responsible for their greater proportional share.

In Riverton City, residential, commercial, institutional and industrial properties all pay a stormwater utility fee.  Cities in accordance to the relatively new Stormwater Industry usually base 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 City.  The runoff expected from residential properties is estimated by measuring the impervious area of representative residential property samples of varying , density, size and market type unique to City.  All residential properties pay the same unit fee but commercial, institutional and industrial properties 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.
