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

6 required geotechnical analysis to determine the slope stability and the potential for rockslides. If the developer is unable to obtain the approval of the owner, then the Geotechnical Engineer shall evaluate the worst case scenario and shall provide an appropriate rock fall zone as discussed above. 15. The developer of a parcel with steep slopes shall prepare a maintenance plan to ensure that the slope is maintained in a safe and stable condition over the years. The maintenance plan shall include site inspections every two (2) years which would include visual observations with pertinent photos of the slope, rock face, and vegetation status at the site. The steep slope maintenance plan must be prepared by a New Jersey Licensed Geotechnical Engineer and must be recorded against the deed of record for each property on which the steep slope is located. The steep slope maintenance plan shall address, but not be limited to, the following: monitoring movement & property condition changes, inspection & maintenance of slope drains, installation of drought-tolerant ground cover, over-irrigation of slope landscaping, direct drainage to slopes, disposal of soil or debris on slopes, ponding of water against retaining walls, monitoring movements and property condition changes. If any deficiencies are noted during the inspection, the necessary corrective action must be taken. Copies of the inspection reports must be filed with the Township of West Orange immediately following completion of the inspection. 16. For areas at the top of a steep slope or adjacent to a parcel with steep slopes, a minimum setback of 50 ft is required from the top of slope to any proposed improvements such as buildings, roads, parking lots, septic fields, swimming pools, hot tubs, ponds, or other uses at or near the top of steep slopes, except as otherwise recommended by a qualified professional. Where development is near steep slopes greater than 30%, increase setback to a minimum of 100 feet, except as otherwise recommended by a qualified professional. The minimum setback shall be established considering site-specific topographic conditions and the recommendations of the qualified Professional Geotechnical Engineer performing the slope stability analysis 17. Other engineering data deemed reasonably necessary by the Township Engineer and Planner to determine compliance with this chapter. §

No soil or vegetation shall be disturbed or structures constructed within 100 feet of the ridge line, cliff face, and rock cuts along the roadways or quarries as defined herein, including but not limited to those identified in Exhibit A attached hereto, dated December 4, 1989, unless otherwise recommended by a qualified Professional Geotechnical Engineer performing the geotechnical analysis stipulated in paragraph 12 above.
