Introduction “Charleston Harbor is one of the finest natural harbors on the Atlantic Coast. It is one of the most important economic assets of the State of South Carolina serving both commercial and military navigation,” 1 states a 1966 Charleston Harbor Water Quality Study. Fifty three years later that still rings true. Preserving the harbor’s water quality is just as important today, as the city and its economy continue to grown dramatically. Charleston is no stranger to growth or history, as it was advantageously established on the peninsula between the Ashley and Cooper Rivers, and its harbor has been an economic center since early colonial days. The water quality study is a reminder of the challenges still ahead for South Carolina’s shoreline. Land development and large commercial or industrial sites, in particular, can each have exponential effects on nature’s own management of rainfall and runoff. New impervious development creates immediate point sources for pollution which could contribute to nasty algae blooms and environmental deterioration that spreads from the shoreline; damaging wetlands, waterways and eventually the local tourism industry.

Situation Brigade Street in Charleston is within reach of the Cooper River, an area with a rich history of tourism and wildlife, at the mouth of Charleston Harbor. The new owner/developers and the engineerinng firm, Thomas & Hutton, were presented with a number of additional stormwater design challenges as major plans were in place for a large-scale multi-family home residential development. First, 107 Brigade Street or Pollack Shores development’s known groundwater elevations are very shallow, with pre-existing contaminated soils and a drainage pattern toward the adjacent protected wetland. The location and conditions would need feasible water quality solutions that could address high water tables, minimal space, contaminated soils, and strict regulations on nitrogen pollutants.
