Stanfiec CITY OF ELK RIVER -STORM WATER UTILITY Proposed Storm Water Utility Fees June 25, 2012 4.0 Proposed Storm Water Utility Fees 4.1 HOW THEY ARE CALCULATED Storm water utility fees are based on the user's share of the costs for the utility. This is the most equitable and practical means of financing these ongoing operations. Conceptually, users pay a storm water utility fee in proportion to the amount of storm water runoff generated by their property during a defined design storm. A storm water utility fee is charged to all "users" within the city based on the amount of runoff that each property generates. The runoff generated relates directly to the amount of hard surface, or impervious area, found on the property. Hard surfaces such as rooftops, driveways, and parking lots prevent rainfall from infiltrating into the ground, thus increasing the amount of runoff that a property generates. Consequently, a property with more impervious area uses the system to a greater extent than a property with less hard surface. The amount of impervious surface was used to determine the fee structure. The general land use classification and current parcel coverage within the City of Elk River were used for the generation of this SWU. A typical residential lot defines the SWU fee structure's basic unit, the "Residential Equivalency Factor" (REF). This typical residential lot is not representative of any particular residential lot and is used only as a means to calculate the REFs. The typical residential lot for one (1) REF is noted below: • Average Residential Lot Size = 0.35 acres • Average Impervious Area = 21% or 3,231 SF The REFs are divided between two property types noted below: • Residential = 1 REF • Commercial/Industrial/Apartments/Other =Impervious Area/3,231 SF Residential property, regardless of size, and agricultural property that includes a single family/twin home are assigned 1 REF. For other land uses, the REF value is based on the comparative amount of runoff generated by calculated actual impervious areas to the amount generated by the typical residential lot.
