Old Naval Base to Get Recreational Green Space

The Noisette Co.’s big dig to create large water basins on the former Charleston Naval Base later this year will include an unusual feature.

One of the proposed water basins along McMillan Avenue will serve as green space and wetlands, allowing recreational usage most of the time but flooding during significant rain events.

The basins, being built to control stormwater flow toward the Cooper River, will gradually taper down deeper toward the river to allow water runoff from areas along Spruill and Cosgrove avenues adjacent to the Naval Hospital.

The larger basin, a small lake bounded by McMillan and Cosgrove avenues and a proposed extension of Noisette Boulevard near the old Power House, will be 400 feet wide by 800 feet long, always will contain water and will rise and fall with the tidal flows of the Cooper River, said Art Titus, Noisette Co. vice president of operations.

The tidal basin will be about 3 feet deep at low tide and about 6 feet deep at high tide, said Mike Horton, an engineer with Davis & Floyd, who is helping Noisette with design features.

The basin to its west, measuring 400 feet by 400 feet, will be the one that floods during major rain events. It will be a vegetated area with paved, intersecting walkways for pedestrians while also allowing recreational users access to grassy areas. It will be about 2 1/2 feet deep at its lowest point near the main tidal basin.

The stormwater should drain off within four to six hours after a major rain event, Horton said.
Shops, offices and residential units eventually will surround the proposed water basins after they are completed during the next 18 months, Titus said.
