In 2010 the City of Prescott established a stormwater utility. The utility is designed to assist with the management of stormwater and other surface water discharges within the Mississippi and St. Croix Rivers. Management of stormwater is a matter that affects the health, safety, and welfare of the city, its citizens, businesses, and others in the surrounding area. Failure to effectively manage stormwater affects the sanitary sewer utility operations of the city by increasing the likelihood of infiltration and inflow into the sanitary sewer systems. Surface water runoff may cause erosion of lands, threaten residences and businesses with water damage, and create environmental damage to the rivers adjacent to the city. A system for the collection and disposal of stormwater provides services to all properties within the city.
Stormwater utility charges are billed as a line item on the City of Prescott water utility bill. Single family residential, duplex, and 3-plex units shall be charged for 1 equivalent runoff unit (ERU) per unit. Multiple residential units shall be charged one ERU times a factor obtained by dividing the total impervious area of the residential property by the square footage equivalent for one ERU. Nonresidential units shall be charged 1 ERU times a factor obtained by dividing the total impervious area of the nonresidential property by the square footage equivalent for one ERU. The minimum ERU for any parcel or unit will be 0.5 ERU.
Credits may be considered for multiple residential and nonresidential customers who own and properly maintain on-site stormwater management systems that both mitigate flood impacts and provide adequate treatment of pollutants in stormwater runoff utilizing a design that has been approved by the Public Works Director. An application for a credit may be obtained from the Public Works Director.
