RULE E FLOODPLAIN ALTERATION <br />1. POLICY. It is the policy of the Board of Managers to: <br />(a) Protect the lives and property values of persons <br />occupying the flood plains. <br />(b) Enhance the floodplains' water resource values. <br />Water resource values are defined as those <br />characteristics which promote the natural moderation of <br />floods, maintain the streams' water quality, and provide <br />groundwater recharge. <br />(c) Promote the living resource values existing in flood <br />plain areas which include the protection of fish and <br />wildlife resources. <br />(d) Enhance the flood plains' significant cultural <br />values, which include preservation of open space, natural <br />beauty, areas for scientific study, outdoor education, <br />and recreation. <br />2. REGULATION. No person may alter or fill land below the 1001year flood <br />elevation of any public water, public water wetland or other wetlands without <br />first obtaining a permit from the District. <br />For permitting purposes the District is divided into Flood Plain <br />Management Sector A and Sector B. These sectors aid in applying <br />management principles which reflect the hydrologic importance of <br />flood plain across the District. <br />3. CRITERIA FOR FLOODPLAIN ALTERATION. <br />Permitting Requirements for Flood Plain Management Sector A <br />Sector A contains those subwatersheds where the percentage of flood <br />plain to total area is twelve percent or less, and the topography <br />in terms of a generalized slope condition is predominantly greater <br />than twelve percent. Flood Plain Management Sector A includes <br />subwatershed 4,5,7,8,13a,14a,14b,14c,14d,14e,15b and 16. <br />(a) Construction of impervious areas within flood plain <br />areas will not be allowed within the designated <br />groundwater recharge areas for the Prairie du Chien Jordan formation except for <br />road construction, trails, and other recreational improvements. <br />(b) To protect water quality and the conveyance capacity <br />of the flood plain, the District will not permit site <br />development which would involve the outside storage of <br />soluble, toxic, or buoyant materials. Examples of acceptable flood plain uses <br />include open space, golf courses, and parking surfaces located outside of <br />designated recharge areas with less than six inches of <br />flooding occurring over the surface. <br />(c) Encroachment within the 1000year flood plain may <br />occur if all the following conditions exist: <br />(1) The flood plain storage volume after <br />encroachment is equal to or greater than the <br />flood plain storage volume prior to <br />encroachment (compensatory storage is <br />required). <br />(2) This encroachment does not lie within the <br />floodway and does not result in a violation of <br />the District's Wetland Alteration Rule F. <br />(3) Construction or development subject to <br />flood damage will have a minimum floor <br />
