- Operation and Maintenance Plan
Lawrence and Downe Townships, Cumberland County, NJ – CES completed this project for the NJ Department of Treasury, Building and Construction. With a $1.5 million construction cost, this dam reconstruction project required a full hydraulic & hydrology study, schematic design, final design and permitting. The existing 600-foot long Class II earth dam had inadequate spillway capacity and was at risk of failure during the design storm event.
During the conceptual design phase, CES developed several alternative designs for cost and construction feasibility comparisons and presented the comparisons to NJDEP. The analysis led to the selection of the preferred alternative for preliminary and final design to meet the dam safety requirements of the NJDEP.
Design elements of the dam reconstruction included a sheet pile spillway and concrete apron, precast concrete box culvert, articulated concrete block armament and embankment fill for slope stability.
CES provided construction management, inspection, and final closeout services for this project, and also prepared an Emergency Action Plan and an Operation and Maintenance Plan for the dam.

Washington Township, Gloucester County, NJ – Jay Kandle’s family has owed a local recreation and campground business for generations that relies on a large lake for boating and swimming. The dam controlling the lake was old and in need of replacement.
CES reviewed Rowan University’s hydrologic and hydraulic studies. These studies revealed that the existing dam could not handle the design storm as required by the New Jersey Department of Environmental Protection (NJDEP) Dam Safety & Flood Control Section (DSFC).
Mr. Kandle hired CES to provide dam safety inspection services, surveying, dam design, and permitting that included wetlands delineation, land use, dam safety, and soil erosion permit applications. CES also prepared an Emergency Action Plan and an Operation and Maintenance Plan for the dam. The replacement dam consists of a concrete spillway, concrete box pipe, and embankment and roadway improvements. The dam was substantially completed in January 2010.
CES also provided construction management, inspection, and close-out services for the project.

City of Vineland, Cumberland, NJ – The City owned and operated recreation impoundment, located near Delsea Drive (Route 47) and along Burnt Mill Branch of the Maurice River, is a tree-covered earthen embankment with an irregular crest elevation and a reinforced concrete spillway structure at the eastern abutment. The previous dam did not meet the spillway capacity and freeboard requirements of the NJ Department of Environmental Protection’s (NJDEP) Dam Safety & Flood Control Section (DSFC), and therefore required a hydrologic and hydraulic analysis, failure analysis, spillway design storm determination, and rehabilitation to safely pass the spillway design storm.
Following the partial breach of the dam after Hurricane Irene in 2011, the City of Vineland hired CES to coordinate an emergency draw-down and fish salvage, and to provide emergency inspection services. The City also hired CES in 2012 to perform the required hydrologic and hydraulic analysis, dam rehabilitation design, and to develop an Emergency Action Plan and Operation & Maintenance Manual for the dam. All calculations, EAP and O&M documents have been reviewed and approved by NJDEP. CES completed the design and CM/CI stages for rehabilitation, which will include clearing and re-grading of the earthen embankment, installation of overtopping protection, and the restoration of the existing concrete spillway.
Michael Galbraith Park, Westville Borough
CES assisted the Borough of Westville in developing a waterfront park along the Big Timber Creek. The site included a portion of a stream bank stabilization project that had been administered by the NJDEP along Big Timber Creek. Historically, the site was the location of a cement manufacturing facility, which had ceased operations approximately 40 years earlier. All that remained of the former concrete facility were a few concrete pads and the remnants of the rail car unloading dock.
The waterfront park is intended for passive recreation and for providing access to the waterfront. The park includes a parking area for vehicle and boat trailer parking. A boat launch area had already been constructed as part of the NJDEP’s stream bank stabilization project. At the Borough’s request, the boat access was limited to non-motorized craft. The design also included paths, landscaping, and an observation deck. The observation deck was cantilevered over the bank, utilizing existing steel sheet piling.
CES obtained a NJDEP Waterfront Development Permit for the project. Since no wetlands were being disturbed, no additional Division of Land Use permits were required. The project was also reviewed by the U.S. Army Corps of Engineers, Regulatory Branch (Philadelphia); however, it was determined that no ACOE permit was required for the project.

National Park, Gloucester County, NJ – CES is honored to have designed a significant addition to this Revolutionary War site on the Delaware River. Although a part of our past, the park remains an ever relevant part of our County’s beginnings.
The County obtained a 6-acre tract adjacent to the park and designed and specified picnic pavilions, children’s play structures, an office and restroom building, a maintenance building, and nearly a mile of new trails for construction bidding.
The project included the purchase of dirt from a nearby site to raise the waterfront area above flood elevation, and a heavy stone revetment was designed to protect the shore line. Steps and piers were designed to allow public access to the water, and sitting areas were designed and specified. CES provided construction inspection and assisted with construction administration.
Cooper University Health Care Sign Package
Services:

When it was time to revise and increase the visibility of its signage, Cooper turned to CES for site planning and Planning Board representation. CES identified many changes to the proposed signage and completed careful research to identify any issues the Town may have raised. CES prepared and submitted the plan, and our engineers gave testimony for the approval.
CES is proud of our involvement with civil engineering projects, surveying, phase I environmental reports, and other consulting services for many healthcare projects involving hospital construction, urgent care facilities, traffic flow, traffic signals, and signage.
