This study investigated the existing functionality of four stormwater management basins located within the Long Swamp Creek sub-watershed of Toms River. The overall objective of this project was to evaluate each basins existing design characteristics and evaluate how each basin could be redesigned or retrofitted to improve its pollutant removal effectiveness and ability to recharge stormwater. Particular emphasis was placed on the investigation of each basins soil profile characteristics, in particular soil porosity. The QAPP for this project is available separately.
