2151002Princeton Hydro West Essex Stormwater Comments to Planning Board 20250310

Stormwater Management Review for Municipal Planning Board Approval West Highlands, Inc. Block No. 179, Lot No.32, West Orange Township, Essex County, New Jersey March 2025 Princeton Hydro, LLC: 2151.002 15 Figure 10: Profile of BMP 9 showing a sanitary line traveling through it. 3.0 SUMMARY In conclusion, our detailed review has found that the application is not in compliance with applicable State and local stormwater requirements (§25-29). It is my professional opinion that the application does not meet all three central performance requirements of the local stormwater requirements. Since the project has not demonstrated compliance with all three specific stormwater management requirements of the central goals of stormwater management planning as outlined in NJAC 7:8 and §25-29 of the local general ordinance, in my professional opinion, the application is non-approvable as designed. If the application is approved as designed, the development will increase the frequency and severity of damage expected during a flood in the adjacent and downstream areas. I appreciate the opportunity to provide you with these engineering services for you. Please do not hesitate to contact me with any questions regarding this review.
