Revised December 11, 1984 <br />MANAGEMENT OF RUNOFF AND PROTECTION OF WATER QUALITY <br />Flooding problems now occur in the urbanized areas of the watershed and on <br />Lake Minnetonka. Water quality problems exist in many of the lakes and <br />streams throughout the watershed. <br />GOAL Reduce the severity and frequency of flooding and high water and <br />improve the chemical and physical quality of surface water. <br />POLICIES <br />A. Manage stormwater and snowmelt runoff rates on a regional or <br />subwatershed basis throughout the watershed so that future peak rates <br />of runoff into major surface water bodies are reduced or equal to <br />existing rates. <br />B. Implement and encourage non-structural runoff management practices <br />wherever possible using and preserving wetlands, floodplains, and <br />other natural detention basins to reduce runoff rates and non -point <br />nutrient and pollutant loadings. <br />Revised December 17, 1984 <br />EROSION AND SEDIMENTATION CONTROL <br />Sedimentation in lakes and streams and other water courses in the watershed <br />from on -going erosion processes and construction activities reduces hydraulic <br />capacity of streams and degrades water quality. <br />GOAL Control temporary sources of sediment resulting from construction and <br />land development activities and to identify, minimize and correct the <br />effects of sedimentation from erosion prone and sediment source <br />areas. <br />POLICIES <br />A. Require preparation and implementation of erosion control plans for <br />construction and land development activities. <br />B. Encourage best management practices to control erosion, soil loss and <br />resulting sedimentation of water areas. <br />C. Develop a program of corrective measures for maintenance of water <br />bodies to preserve adequate hydraulic and navigational capacity and <br />water quality. <br />
