As per the Township’s Zoning Map (last revised 2020), the subject parcel (Block 106, Lot 20.03) is located in the ‘R-1’ (Residential, 80,000 square foot minimum area) zoning district along Eagle Ridge Way, approximately 200 feet from the intersection of Eagle Ridge Way and Boland Drive. The subject property is approximately 2.067 acres and is presently developed with a single-family house with an attached garage, a pool house that is under construction, and an inground pool that is under construction. Also under construction are drainage collection, conveyance and storage facilities and a retaining wall. Below is a summary of the proposed property improvements: Approximately 1.88 acres of the subject property either has or will be disturbed to accommodate the pool building and inground pool which are under construction and the drainage facilities, some which have been constructed and others to be constructed as part of this application. Since more than one acre of land is being disturbed for these improvements, this application is considered a Major Site Plan under the Township’s Storm Water Management regulations. As stated, the pool building and inground pool are under construction. When the original plans were submitted, less than one acre was being disturbed and thus the improvements were not considered a Major Site Plan. However, during construction it was determined that more than an acre was disturbed and work stopped pending approval of the Planning Board. The pool building and inground pool are considered accessory

owever, during construction it was determined that more than an acre was disturbed and work stopped pending approval of the Planning Board. The pool building and inground pool are considered accessory uses. The engineering drawings do not depict any trees to be removed as any trees disturbed by the construction were previously removed and a permit was issued by the Township Forester. The applicant submitted a Landscape Plan that depicts new proposed plantings. 1. General 1.1. Architectural drawings were not provided as part of the submission materials for the pool building and pool. As such, we are unable to ensure that the proposed building complies with the residential building design criteria specified in Ordinance §25-9.7(b). The Applicant shall provide architectural drawings for further review. However, permits were already issued for these two uses. 2. Demolition 2.1. The Applicant shall provide testimony regarding the intention to remove any additional trees and obtaining a Tree Removal Permit pursuant to Ordinance §25-27. 3. Layout Plan 3.1. The Applicant shall provide testimony regarding the existing site conditions, proposed improvements, and conformance with applicable ordinances and regulations.

23-1345-008 – PB24-19 (TheWayMaker LLC – 40 Eagle Ridge Road) Page 3 of 3 3.2. A boulder wall that is over ten feet in height was constructed along the rear property line. No permit was issued for this wall and since it is over six feet in height, the wall violates Ordinance 25-8.4a. A violation notice was issued. To bring the wall into compliance with the Ordinance, the plan proposes to place fill material along the face of the wall. However, a construction detail of this wall is required and since the original wall exceeded four feet, a building permit must also be obtained. The wall will need to be inspected and certified. 4. Grading & Drainage Plan 4.1. The Applicant’s engineer shall provide details of the previously installed drywell system/seepage tank field. 4.2. The Applicant’s engineer shall provide clarify how stormwater runoff will discharge from the existing drywell system/seepage tank field. If there is an outflow pipe connecting to an off-site system, it shall be detailed on the plans and noted in the stormwater management report. 4.3. The Applicant’s engineer shall explain the purpose of removing the portion of the 36” elliptical pipe and the addition of the proposed single chamber outlet control structure and scour hole at the southwest corner of the property. This change in the drainage system shall also be addressed in the stormwater management report. 4.4. The Applicant’s engineer shall provide results of a geotechnical investigation to ensure the infiltration system meets the requirements of Chapter 12 of the NJ Stormwater Best Management Practices (BMP) Manual. Verification of the depth of bedrock and seasonal high-water table shall be submitted to the Municipal Engineer and confirmed prior to the issuance of a building permit. 5. Landscaping Plan 5.1 Matrix has no comment on the landscaping plan. 6. Soil Erosion & Sediment Control 6.1. The Applicant shall obtain a soil erosion and sediment control permit from the Hudson-Essex-Passaic Soil Conservation District. Matrix reserves the right to review the certification and approved plans from the district. We thank you for the opportunity to be of service to the Township of West Orange Planning Board.
