The plans should be revised to include construction details for the following: a) Trash area. b) Utility trench restoration. c) Electric vehicle charging station. d) Depressed concrete curb (on-site). C. STORMWATER MANAGEMENT COMMENTS 1. On May 20, 2025, the Township of West Orange adopted Ordinance 2918-25 which amended the Township's Stormwater Control Ordinance (SCO). This Ordinance defines a major development as an individual development, including redevelopment, that individually or collectively results in: a) The disturbance of 0.5 acre of land since February 2, 2004. b) The creation of 5,000 square feet or more of “regulated impervious surface” since February 2, 2004. c) The creation of 5,000 square feet or more of “regulated motor vehicle surface” since March 2, 2021, or d) A combination of b and c above that totals 5,000 square feet or more. The same surface shall not be counted twice when determining if the combination area equals one-quarter acre or more. The Stormwater Management Report indicates that 4,746 sf of regulated impervious coverage and 6,473 sf of motor vehicle surface coverage is proposed. As a result, this project appears to be classified as a major development and must comply with the requirements outlined under the Stormwater Control Ordinance (Section 25-29). In addition, the Applicant must submit an Application for Stormwater Permit and must pay the stormwater permit fee stipulated in Resolution 153-25 which was adopted by the Township on June 24, 2025. 2. Asoil report must be provided in accordance with Section 25-29.10 of the Township Code. Further, permeability testing should be provided to verify the exfiltration rates utilized within the hydrograph routings.
