Statement of intent. This overlay district is intended to prevent the destruction of valuable natural resources, particularly woodlands, wildlife habitat areas, significant water recharge and discharge areas, prairies, recreational and scenic areas, natural scientific areas, areas with poor soils or high groundwater, and areas of steep topography (e.g., hillsides, bluffs, etc.). Regulation of these areas, including environmental corridors, should serve to control runoff, erosion and sedimentation, protect the natural resource base, promote and maintain the natural beauty of the area, and promote the health, safety and welfare of City residents.
