2678-22 Ordinance - Steep Slope - Amended Rev. 5 (002).pdf

5 2. Erodibility potential of exposed soils; 3. Length, steepness and surface roughness of exposed slopes; 4. Resistance of soil to compaction and stability of soil aggregates; 5. High water table, water infiltration capacity and capacity of soil profile; 6. Type and location of construction activity, including the amount of site grading; 7. Location of construction access roads; 8. Storm water management plan; 9. Soil erosion and sediment control plan, including but not limited to a plan explaining how the applicant will minimize adverse impacts upon existing natural features; 10. Plans and specifications for any retaining walls, steps, or other soil protective structures proposed; 11. A stabilization and revegetation plan prepared, signed and sealed by a New Jersey professional engineer, including a complete description of the existing vegetation, the vegetation to be planted and slope stabilization measures to be installed; 12. The developer of a parcel with steep slopes shall submit a geotechnical analysis of the slope stability and the need for remedial work such as shaping of the rock face, pinning and/or grouting of the exposed rock for stabilization and the installation of safety netting in areas of concern. The geotechnical analysis shall be performed by a qualified Professional Geotechnical Engineer licensed in the State of New Jersey, with a minimum of five (5) years of professional experience in the geotechnical field. The analyses of local and global, rock slide, and rock face slope stability shall be conducted by a qualified Professional Geotechnical Engineer adhering to the principles of Geotechnical Engineering for soil and rock mechanics, and utilizing conventional methods of analyses. The determination of slope stability shall include, but is not limited to, geologic research, subsurface explorations, laboratory testing to assess soil/rock properties, visual evaluations, stereoscopic analyses of the rock face, and adequate factors of safety against failure. 13. In areas where the potential for rockslides exist, a rock fall zone, or catchment area width, shall be provided at the toe of slope. The required width of the rock fall zone would be determined by the Geotechnical Engineer utilizing established criteria such as those developed by Arthur M. Ritchie and included in the Rockfall Catchment Area Design Guide.

If the parcel being developed is adjacent to a parcel with steep slopes, then the developer shall obtain the approval of the owner of the adjacent parcel to perform the
