Abstract: The U.S. Army Corps of Engineers (Corps), Jacksonville District, is proposing to conduct periodic maintenance dredging of the federally authorized Ponce de Leon Inlet channel (hereafter referred to as the Inlet), including the entrance, throat, and inner channels leading to the Atlantic Intracoastal Waterway (IWW) in Volusia County, FL. This includes Cuts 1A to 3A, 1S to 3S, and 3N to 13N, along with wideners where the channel converges with the IWW (see Figure 1, Project Map). The Inlet entrance channel across the ocean bar will be maintained to a depth of -15.0 feet mean lower low water (MLLW), the Inlet throat to a depth of -12.0 feet MLLW, the southward channel to the IWW to a depth of -12.0 feet MLLW, northward channel Cut-3N, Cut-4N and Cut-5N to a depth of -12.0 feet MLLW, and remaining north channel connector to the IWW to a depth of -7.0 feet MLLW. For each cut, an allowable 2-foot overdepth is authorized. Dredged material would be placed either on the beach north of the north jetty between Florida Department of Environmental Protection (FDEP) monuments R-140 to R-148, or on the beach south of the south jetty between R-158 and R-177. Placement could also occur at the nearshore area located 1 mile south of the south jetty some 1500 feet offshore, at depths between contours -8.0 feet and -18.0 feet MLLW, or at the north nearshore placement area, located north of the north jetty adjacent to the shoreline from R-140 to R-148 also at depths of -8.0 to 18.0 feet MLLW. The dredged material consists of fine grained sand with percent fines ranging from less than 1% to less than 20% passing through the #200 sieve.
