A traffic impact analysis was conducted for the proposed Wescott Park recreational development located in the City of North Charleston, South Carolina. The proposed development will consist of a 24-acre park, which will include a baseball complex with three ball fields, a baseball training facility, an outdoor classroom and a multi-use field, concessions and associated facilities, picnic shelters, and various play-garden facilities.
Access to the park will be provided through one full-access driveway along Dorchester Road, opposite of Cannondale Drive at an existing median opening. The buildout date of the park is expected to be in late 2012; to provide for a conservative analysis, future-year 2013 conditions was selected for the analysis of the Build scenario.
The results of the analyses indicate that the signalized study intersections currently operate and are expected to continue to operate at an acceptable LOS. At the unsignalized Dorchester Road & Project Driveway/Cannondale Drive intersection, the results of the analysis show that the side-street approach currently operates at LOS E conditions in the Saturday peak hour and is expected to operate at LOS F conditions for 2013 Build Conditions. However, based upon a field review of the intersection, side-street traffic currently has adequate gaps along Dorchester Road and is expected to continue to in the future due to metering from the adjacent signalized intersections. The wide Dorchester Road median at the intersection also allows for two-stage gap acceptance.
In addition, the results of a preliminary traffic signal warrant review at the unsignalized intersection indicate that the projected side-street traffic volumes are not expected to meet any traffic signal warrants during the study peak hours. Based upon consideration of these factors, no signalization improvements are recommended at this time for the Project Driveway intersection along Dorchester Road.
Lastly, the results of the turn lane analysis indicated that the total turn lane lengths for the proposed southbound left-turn lane and northbound right-turn lane into the Project Driveway are recommended to be 350 feet and 200 feet, respectively.
