CR 667 (Cohawkin Road) and CR 673 (Cedar Road) Intersection Improvements in Gloucester County

FY What is the fiscal year: Please provide the County name: County Local Concept Development Intersection Study for Project Title . The Delaware Valley Regional Planning Commission (DVRPC) on behalf of Gloucester County, New Jersey is seeking consultant support for the preparation of a Local Concept Development (LCD) study being advanced through its Local Capital Project Delivery (LCPD) Program. This program is consistent with the Project Delivery Process (PDP) implemented by the New Jersey Department of Transportation (NJDOT). Through this Request for Proposals (RFP), DVRPC is seeking to engage one (1) qualified consulting firm to provide professional consulting services to Gloucester County for conducting an LCD study for necessary Intersection Improvements to Cohawkin Road (CR 667) and Cedar Road (CR 673), in the Townships of Mantua and East Greenwich, Gloucester County. The existing intersection configuration is a ‘Y’ intersection, with a stop condition only on Cedar Road (CR673). The available line of sight for motorists entering the intersection from Cohawkin Road does not meet minimum design standards, creating a safety concern. Vehicle conflicts also exist at this intersection. Cars traveling north on Cohawkin Road frequently make the left turn onto Cedar Road in an unsafe manner, turning directly in front of active southbound traffic without stopping. The consultant shall evaluate the existing intersection configuration, roadway geometry, line of sight, and general traffic operations to identify all opportunities of safety improvement at the intersection. In addition to evaluating potential geometric improvements at intersection, the consultant shall address the existing drainage deficiencies along Cohawkin Road, particularly near and through the intersection with Heritage Road where it connects Cedar Road with Cohawkin Road at the northern limits of the project area. The three houses at the southwest corner of the Cohawkin Road and Heritage Road intersection experience flooding during periods of intense rainstorms. The drainage area includes fields south of the intersection (on both sides of Cohawkin Road). Runoff from these fields drain into an existing undersized system which ultimately discharges to the pond located at the corner of Cedar Road and Heritage Road (northwest corner of the project). The consultant shall evaluate the existing drainage system to minimize localized flooding of the adjacent residential properties. The study shall include evaluation of the existing drainage system including capacity, condition, drainage areas, drainage patterns and identification of any additional factors contributing to the observed flooding. The consultant shall identify appropriate alternatives to address the existing deficiencies and improve stormwater management within the project area.
