Station 18-19 Stormwater Improvements (FEMA 4241)

The Town of Sullivan’s Island proposes to construct drainage improvements in two priority sub-basins:

  •  Station 18 Street/Atlantic Avenue Watershed Basin (Sta. 18)
  •  Station 18.5 Street/Flag Street (Sta. 18.5)

The drainage improvements are intended to provide drainage and alleviate flooding including reoccurring structural flooding with the basins. The improvements will include installing new pipes, inlets, swales, stormwater pump stations, and structures while re-establishing existing open channels and swales where possible.
