<br />4 Amended: <br />3 Amended: 9/4/01 <br />2 Amended: 6/27/01 <br />1 Amended: 1/10/01 <br />Effective 9/5/00 <br />City of Centorville Ord. #4 <br /> <br />A. Permanent natural buffer areas and appropriate erosion control measures be taken <br />surrounding wetland areas to prevent sedimentation of the wetland; and <br /> <br />B. Wetlands may not be drained or filled, wholly or partially, unless replaced by <br />restoring or creating wetland areas of at least equal public value. Wetland <br />encroachment must be guided by the following principles in descending order: <br /> <br />1. Avoiding the direct or indirect impact of the activity that may <br />destroy or diminish the wetland; and <br /> <br />2. Minimizing the impact by limiting the degree or magnitude of <br />the wetland activity and its implementation; and <br /> <br />3. Rectifying the impact by repairing, rehabilitating, or restoring <br />the affected wetland environment; and <br /> <br />4. Reducing or eliminating the impact over <br />time by preservation and maintenance operations during the <br />life of the activity; and <br /> <br />5. Replacing or providing substitute wetland resources or <br />environments. <br /> <br />Division 150: Woodland Preservation <br /> <br />In residential areas, structures shall be located in such a manner that the maximum number of woodlands <br />shall be preserved. If large numbers of trees are cut in residential areas, trees shall be replanted in a <br />density and manner satisfactory to the City Council. Clear cutting of woodlands for non-agricultural <br />purposes is prohibited, unless the action involves a utility or roadway, required by the public, and includes <br />a reforestation plan required by the City Council. <br /> <br />Division 155: Erosion and Sedimentation Control <br /> <br />No land occupant or developer in the City shall cause or conduct any land disturbing activity which <br />causes excessive erosion or sedimentation, or which results in damage to water or soil resources. All <br />development in the City shall conform to the natural limitations presented by the topography and soil <br />types in order to minimize soil erosion and sedimentation. Erosion and sedimentation controls shall be <br />consistent with the MPCA's, "Best Management Practice". <br /> <br />Land disturbing activities shall occur in increments of workable size such that adequate erosion and <br />ediment controls can be provided throughout all phases of the development. The smallest practical area <br />of land shall be exposed or otherwise disturbed at anyone period of time. Areas where natural <br />vegetative barriers are not enough to contain erosion and sedimentation from penetrating water bodies, <br /> <br />Page 48 of 69 <br />
