525 Northfield Avenue, West Orange, NJ January 27, 2026 Page 2 of 4 4). Resistance of soil to compaction and stability of soil aggregates; ANS: As indicated in item-3 above, 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. Visual observation has indicated no accumulation of rocks at the bottom of the slope indicating stone/rock pieces being stable and not prone to movement. 5). High-water table, water infiltration capacity and capacity of soil profile; ANS: Our soil boring B-6 performed on 8-20-2024 have indicated static water at 11'-1" below grade. Seasonal High-Water table at 6'-0"below grade. Inboring B-8, we have noted static water at 8'-9" below grade. Existing slope behind the retaining wall not have any detrimental effect on the stability of the slope due to water table 8 to 11 feet below the base of the hill. 6). Type and location of construction activity, including the amount of site grading; ANS: The construction activities are shown of the site plans prepared by Jarmel Kizel, Inc. The steep slope area consists of 26,433sf of which 7,781sf is proposed to be disturbance. A retaining wall with a maximum height of 6 feet is proposed along the entire toe of slope, which will stabilize the slope. 7). Location of construction access roads; ANS: Construction access will be provided from the existing paved parking area at the toe of slope. 8. Stormwater management plan; ANS: A stormwater management report has been prepared by Jarmel Kizel in compliance with Township stormwater Control Ordinance 25-29. 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; ANS: A Soil Erosion and Sediment Control plan has been prepared as part of the site plan set by Jarmel Kizel to comply with the Hudson Essex Passaic Soil Conservation District. 10). Plans and specifications for any retaining walls, steps, or other soil protective structures proposed; ANS: The proposed retaining wall detail has been provided on the site plans. The wall will be a large block wall with a height of 6 feet to minimize steep slope disturbance. The new retaining wall design will not

posed retaining wall detail has been provided on the site plans. The wall will be a large block wall with a height of 6 feet to minimize steep slope disturbance. The new retaining wall design will not affect the stability of the slope. Final design and specifications shall be provided to the West Orange Building Department during construction permit process. 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; ANS: A landscaping plan has been provided as part of the site plan set. The ground cover and landscaping proposed will minimize steep slope erosion. The retaining wall will have a stormwater drain behind it that will prevent any hydrostatic pressure built-up at the base of wall.
