525 Northfield Avenue, West Orange, NJ January 27, 2026 Page 3 of 4 Additionally, a Soil Erosion and Sediment Control plan has been prepared by Jarmel Kizel, Inc. to comply with the Hudson Essex Passaic Soil Conservation District. 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 years of professional experience in the geotechnical field. The analyses of local and global, rockslide, 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. ANS: Not Applicable, the slope is vegetated with existing trees. Rock faces are not visible. 13). In areas where the potential for rockslides exists, 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. (https://www.dot.ny.gov/main/businesscenter/designbuildprojectl3/repository/ Oregon%20DOT%20Rockfall%20Area%20Design%20Guide%20%2020141211.pdf) ANS: Since existing slope will not be disturbed, its length, width and height will remain untouched, it has been stable and incident free for over 65 to 75 years, we do not anticipate any slope stability issue due to a retaining wall construction at the base. Proposed new tree planting will add in erosion prevention after tree roots hold the soil in few years of their growth. The slope is vegetated with existing trees. 14). If the parcel being developed is adjacent to a parcel with steep slopes, then

n prevention after tree roots hold the soil in few years of their growth. The slope is vegetated with existing trees. 14). 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 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. ANS: It is my professional opinion that there is no slope stability concern at his time. Since existing slope will not be disturbed, its length, width and height will remain untouched, it has been stable and incident free for over 65 to 75 years, we do not anticipate any slope stability issue due to a retaining wall construction at the base. Proposed new tree planting will add in erosion prevention after tree roots hold the soil in few years of their growth. The slope is vegetated with existing trees. 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 years which would include visual observations with pertinent photos of the slope, rock face, and vegetation status at the site. The steep slope maintenance planmust 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 and property condition changes, inspection and maintenance of slope drains,
