Consulting & Municipal ENGINEERS Chairman and Members of the West Orange Township Zoning Board September 9, 2024 Re: PSE&G Company (ZB-24-06) Our File No. 115.WRZ0155.V04 Preliminary & Final Site Plan with ‘C’ and ‘D’ Page 4 Variances and Tree Removal Permit - Review #2 Research Zone and has an area of approximately 23.36 acres.

It shows on sheet 792788 of the West Orange Switching Station plans that the existing sidewalk along the Prospect Avenue and Mt. Pleasant Avenue site frontages is to be removed. However, it shows on sheet 3 of the Site Plan drawings that the existing sidewalk is to be removed/replaced if necessary. This discrepancy must be resolved. Please note that our office is opposed to removal of the existing sidewalk along the site frontages. Sheet 792796 includes a Standard Concrete Driveway and Concrete Apron detail. Therefore, the plans must be revised to show where a concrete driveway and concrete apron are proposed. Sheet 792797 includes a Typical Bollard Detail. Therefore, the plans must be revised to show the locations where bollards are proposed. Based on our review, we find that the following utility conflicts exist on the West Orange Switching Station plans: a) Existing electric line and proposed manhole MH-01 b) Existing gas line and proposed manholes MH-03 and MH-04 and storm pipe SD- 05 c) Existing electric line and proposed manhole MH-04 d) Existing gas line and proposed manhole MH-06 e) Existing duct bank and proposed storm pipe SD-10 Based on our review, it appears that utility conflicts may exist at the following locations: a) Existing electric line and proposed storm pipe SD-04 b) Existing duct bank and proposed storm pipe SD-21 c) Existing duct bank and proposed storm pipe SD-22 d) Existing gas and electric lines and proposed storm pipe SD-10 It shows on the plans that Basins BR-04 and BR-05 will be located very close to the adjoining drive paths. The Applicant should address the Board regarding the need to install guide rails to prevent vehicles from driving into the basins. C. DRAINAGE COMMENTS 1. The proposed development will result in the disturbance of more than one acre. As a result, it is classified as a Major Development which requires that the project be designed to meet the stormwater runoff

roposed development will result in the disturbance of more than one acre. As a result, it is classified as a Major Development which requires that the project be designed to meet the stormwater runoff quality, quantity and groundwater recharge standards using green infrastructure. We note that trench drains are proposed adjacent to each bioretention basin to prevent off-site drainage from entering the bioretention basins. The flows from the trench drains will connect to a separate stormwater conveyance system which will discharge to the ‘S:\West Orange\Zoning Board\1 15 WRZ0155 V04 - PSE&G Company\24-09-09 Review #2 docx

Pleasant Avenue. The areas that will discharge to the trench drains are not proposed for development and will remain in their existing condition. The Bioretention and Control Structure Elevations and Control Orifices table on sheet 792798 should be revised to label the Top of Basin Wall Elevation as E to match the Typical Concrete Lined Small-Scale Bioretention with Underdrain Detail on the same sheet. The Bioretention Media Notes on sheet 792798 should be revised to include a note which states “The soil bed material must be placed in lifts not to exceed 6 inches’. The plans should be revised to provide maintenance access to each proposed basin. It shows on the Bioretention and Control Structure Elevations and Control Orifices table that each basin will have a freeboard of only 0.1 feet between the top of wall and the top of overflow grate. It is our recommendation that a minimum freeboard of 1.0 ft be provided. It shows on the Conduit Table in the Stormwater Report that the following pipe runs do not have adequate capacity to accommodate the design flow: a) SD-01 b) SD-02 c) SD-04 d) SD-12 e) SD-21 f) SD-22 g) SD-23 h) SD-24 i) SD-25 The Small Scale Bioretention Outlet Structure detail on sheet 792798 shows a 2.5” water quality control orifice with a trash rack at Elevation G. It is our understanding that the 4” perforated underdrain pipe will connect to the outlet structure at this location. Therefore, the trash rack is not required at this location and should be deleted. A detail showing how the 2.5” water quality control orifice will be installed must be added to the plans. The Small Scale Bioretention Outlet Structure detail on sheet 792798 shows that a trash rack is proposed on the top of the structure. Therefore, a detail of this trash rack must be added to the plans. Revise plans and maintenance plans to include inspection ports for the basins’ underdrains. In addition, provide a detail of these inspection ports. The List of

rash rack must be added to the plans. Revise plans and maintenance plans to include inspection ports for the basins’ underdrains. In addition, provide a detail of these inspection ports. The List of Stormwater Management Measures in Stormwater Management Measures Maintenance Plan and Field Manuals must be revised to include the state plane coordinates for each basin.
