<br />GENERAL POLICY STATEMENT <br /> <br />The Rice Creek Watershed District (District) is a political <br />subdivision of the State of Minnesota, established under the <br />Minnesota Watershed Law. The District is also a watershed <br />management organization as defined under the Minnesota Metropolitan <br />Surface Water Management Act, and is subject to the directives and <br />authorizations in that Act. Under the Watershed, Law and the <br />Metropolitan Surface Water Management Act, the District exercises <br />a series of powers to accomplish its statutory purposes. The <br />District's general statutory purpose is to conserve natural <br />resources through development planning, flood control, and other <br />conservation projects, based upon sound scientific principles. <br /> <br />As required under the Metropolitan Surface Water Management Act, <br />the District has adopted a Watershed Management Plan, which <br />contains the framework and guiding principles for the District in <br />carrying out its statutory purposes. It is the District's intent <br />to implement the Plan's principles and objectives in these rules. <br /> <br />Land alteration affects the rate, volume, and quality of surface <br />water runoff which ultimately must be accommodated by the existing <br />surface water systems within the District. The watershed is large, <br />201 square miles, and its outlet, Rice Creek, has limited capacity <br />to carry flows. Flooding problems already occur in the District's <br />urbanized areas along lower Rice Creek and other localized areas. <br /> <br />Land alteration and utilization also can degrade the quality of <br />runoff entering the streams and waterbodies of the District due to <br />non-point source pollution. Lake and stream sedimentation from <br />ongoing erosion processes and construction activities reduces the <br />hydraulic capacity of waterbodies and degrades water quality. <br />Water quality problems already exist in many of the lakes and <br />streams throughout the District. <br /> <br />Projects which increase the rate or volume of stormwater runoff can <br />aggravate existing flooding problems and contribute to new ones. <br />Projects which degrade runoff quality can aggravate existing water <br />quality problems and contribute to new ones. Projects which fill <br />floodplain or wetland areas can aggravate existing flooding by <br />reducing flood storage and hydraulic capacity of waterbodies, and <br />can degrade water quality by eliminating the filtering capacity of <br />those areas. <br /> <br />In these rules the District seeks to protect the public health and <br />welfare and the natural resources of the District by providing <br />reasonable regulation of the modification or alteration of the <br />District's lands and waters to reduce the severity and frequency <br />of flooding and high water, to preserve floodplain and wetland <br />storage capacity, to improve the chemical, physical and biological <br />quality of surface water, to reduce sedimentation, to preserve <br /> <br />1 <br /> <br />I <br />,I <br />, <br />I <br />- <br />I <br />I <br />I <br />I <br />II <br />I <br />I <br />I <br />I <br />I <br />I <br /> <br />I <br />.. <br />I <br />
