Our firm performed a detailed hydrologic and hydraulic drainage study of the watershed draining to the main access road at Picatinny Arsenal. The watershed in this section of Parker Road (Route 15 to 1st Street) drains from the ridgeline east of Parker Road via overland and channelized flow to approximately 20 culvert crossings in the project area. Drainage improvements were designed and implemented to improve stormwater management along this critical access.
Our firm provided conceptual and final design, bidding, and construction phase services for the reconstruction of the school’s primary parking lot. Stormwater management aspects of the project consisted of the re-design and replacement of existing seepage pits for rooftop runoff with overflows into the site’s existing stormwater management system.
Culver Lake is a 555-acre natural lake located in northwestern New Jersey. The contributing drainage area to the lake is approximately 3,840 acres. Of the 40 stormwater outfalls to the lake, our firm focused its effort on five specific outfalls located along the northwest shore line. They were determined to be contributing the greatest sediment inflow to the lake. Work included investigation of basins and outfalls, a TR-55 stormwater analysis for each outfall, a conceptual remediation plan, and an evaluation report with recommendations. Remedial measures are ongoing.
