As per the Township’s Zoning Map (last revised 2020), the subject parcel (Block 80.03, Lot 10) is located in the ‘R-1’ (Residential) zoning district along Ridge Road, approximately 300 feet from the intersection of Ridge Road and Mount Pleasant Avenue and across the street from the Brookdale West Orange Senior Living facility (located in the R-2 District). The subject property is approximately 5.77 acres and is presently undeveloped, wooded land. Matrix further understands that the Applicant intends to construct a two-and- a-half story single-family residence with an attached garage, as well as an 800 square foot (SF) outdoor swimming pool and 1,300 SF pickleball court. Below is a summary of the proposed property improvements: Approximately 42,241 SF (0.97 acres) of the subject property will be disturbed to accommodate the proposed single- family residence, accessory uses (i.e., swimming pool and pickleball court), driveway and utility improvements.

Portions of the property, mainly along the perimeter, contain steep slopes equal to or greater than 10%. According to the engineering drawings (see Sheet 3, Demolition, Steep Slope and Tree Removal Plan), disturbances in steep slope areas will conform with all maximum disturbance areas for steep slopes as

ccording to the engineering drawings (see Sheet 3, Demolition, Steep Slope and Tree Removal Plan), disturbances in steep slope areas will conform with all maximum disturbance areas for steep slopes as provided in Ordinance §25-28.8. 1.
