XX ASSOCIATES Chairman and Members of the West Orange Township Zoning Board January 20, 2023 Re: Seton Hall Preparatory School (ZB-22-12) Our File No. VWRZ0082.02 Preliminary & Final Site Plan with ‘C’ Page 3 and ‘D' Variances - Review #1 B. DESIGN COMMENTS 1. Based on our review, we find that the following items from the Township's Site Plan/Subdivision Checklist must be addressed: a) Item #23 — List of required regulatory approvals or permits. b) Item #35 — Drainage Calculations. The Sustainability Checklist Form submitted by the Applicant is blank. Therefore, the Applicant should submit a completed Sustainability Checklist Form which details the sustainable design features that are proposed for this project. According to our records, an area of steep slopes exists along the easterly side of the site. Ordinance 2678-22 establishes controls which regulate development in areas adjacent to steep slopes. Therefore, the Applicant must address the requirements set forth in this Ordinance. It shows on the Overall Site Plan (sheet SP-103.00) that the Applicant proposes to add 2 parking stalls adjacent to the relocated maintenance building. However, this work is not included within the limits of the Proposed Area of Improvements shown on the Overall Site Plan and no details have been provided regarding the work that is proposed in this area. Therefore, the plans must be revised accordingly. The Applicant proposes to increase the footprint of the existing building by approximately 5,334 sf. In addition, the Applicant proposes to add 2 parking stalls adjacent to the relocated maintenance building. Therefore, the Applicant should address the Board regarding their plans to mitigate the increase in runoff that will result from the proposed improvements. It shows on the Site, Grading, Utility, and Erosion Control Plan (sheet SP-103.10) that a covered canopy is proposed on the northerly side of the new addition. However, a covered canopy is not shown on the architectural plans at this location. This discrepancy must be resolved. It shows on the Site, Grading, Utility, and Erosion Control Plan that a covered canopy is proposed on the southerly side of the new addition. The plans should be revised to clarify the proposed surface treatment beneath this canopy. Is a concrete patio proposed beneath the canopy? The size and location of the proposed water service

dition. The plans should be revised to clarify the proposed surface treatment beneath this canopy. Is a concrete patio proposed beneath the canopy? The size and location of the proposed water service to the health and fitness center must be shown on the Site, Grading, Utility, and Erosion Control Plan. It shows on the Site, Grading, Utility, and Erosion Control Plan that the 82 If of 18” HDPE pipe from Pr. Type ‘A’ Inlet to the Existing Manhole will have a slope of 0.4% whereas our office calculates the proposed slope to be 0.5%. This discrepancy must be resolved. ‘S:\West Orange\Zoning Board\VWRZ0080.02 - Seton Hall Preparatory School\23-01-20 Review #1.docx
