Section 8-525 Slopes of Thirty Percent (30%) Or More
The following regulations apply to slopes of thirty percent (30%) or more:
8-525.A. Development Discouraged. Development shall be discouraged on slopes of thirty percent (30%) or more, unless problems of stability and erosion can be overcome. Any development approval shall be based on a detailed site survey including geologic and engineering analysis and shall include but not be limited to complying with the following:
8-525.A.1. Cuts shall not be made into slopes steeper than thirty percent (30%) unless direct slope mechanical support is provided when necessary.
8-525.A.2. Steepness of cut and fill slopes shall be the maximum which will ensure stability and still allow revegetation. Maximum standards shall be a ratio of one and one half to one (1 1/2:1) for cuts, and two to one (2:1) for fill areas.
8-525.A.3. Exposed areas shall not be left open or uncompleted between November 1st and March 31st.
8-525.A.4. Mulches or temporary cover shall be used on exposed soil areas and reestablishment of permanent vegetation and installation of erosion control measures shall take place as soon as possible.
8-525.A.5. Natural drainage patterns shall be incorporated into the development plan. Adequately designed culverts, sediment basins and other engineering measures shall be used where necessary to control erosion.
