<br />Feasibility Study 112316 <br />City of Lino Lakes, Minnesota <br />The “S” term can be expressed in terms of the runoff index, or curve number (CN). <br />The graph below, demonstrates the increased amount of runoff generated by different land use types. This <br />chart clearly demonstrates why a parking lot (with runoff of approximately 1.7 inches) should pay more per <br />acre than a single-family home with runoff of approximately 0.3 inches. The calculations below are based <br />upon a 2 inch rainfall in an area with sandy soils. <br /> <br />0.00 <br />0.20 <br />0.40 <br />0.60 <br />0.80 <br />1.00 <br />1.20 <br />1.40 <br />1.60 <br />1.80 <br />ForestPasture (Fair condition)Pasture (Poor condition)1 acre lotsSingle FamilySoybeans (straight row)Corn (straight row)Two Family1/8th acre lotsIndustrialCommercialParking LotsNRCS/SCS Runoff Model <br />Runoff <br />(Inches) <br />Assumptions: <br />P=2" <br />Type B Soil <br />Soil Mosture Condition II <br /> <br /> <br />How Will the Utility Benefit Lino Lakes? <br />The utility benefits the community by providing a dedicated fund for surface water management activities, <br />including the required activities under the National Pollutant Discharge Elimination System (NPDES) Storm <br />Water Permit Program. In addition to the required Storm Water Pollution Prevention Plan (SWPPP) <br />activities, benefits may also be realized more generally in the following areas: <br />• Flood reduction and protection; <br />• Water quality improvements; <br />• Wetland protection and enhancement; <br />• Erosion and sediment control; <br />• Drainage system construction and maintenance; <br />• Community education; <br />• Improved fish and wildlife habitat; and <br />• Enhanced recreational opportunities.
