Plans for Phase Two of shoreline rehabilitation on the north end of Jekyll Island’s oceanside are now open for public comment, with the release of those plans by the state Department of Natural Resources’ Coastal Resources Division at the end of September.
The Jekyll Island Authority approved a proposal in April by S.J. Hamill of Charleston, S.C., to conduct the revetment project, at an announced cost of $4.98 million. Work started in mid-June on Phase One of the project, which included adding new, larger revetment rocks. Some of those rocks weigh as much as two tons and are meant to put the revetment as a height of 10.5 feet at its highest point. Phase One work is expected to continue throughout the year.
Phase Two is to involve around 16,000 feet of oceanfront, reaching from 2,000 feet south of Capt. Wylly Road up to the Driftwood Beach access trail. From there, the phase is segmented into two sections — the roughly 15,000-foot southern area and 1,000-foot northern area.
Part of the effort involves the removal of debris, but it is supposed to be supervised to ensure that nothing is removed that shouldn’t be removed.
“The large dead trees along the transitional shoreline — northern section of the project area — are considered, by the applicant, to be important public recreation, local culture and island history,” according to the proposal. “The large trees in this area are proposed to be left in place, to the extent practical. A representative from the JIA conservation office will guide and observe this effort. Debris removal will utilize typical earthmoving equipment capable of selectively removing debris.”
Sand is also set to go in landward of the rock revetment, with a geotextile filter underlying the sand.
“The filter will allow upland runoff/groundwater and overtopping during extreme events to flow through, while retaining the proposed sand materials landward of the revetment,” according to the proposal.”
Along the southern end, sand is to restore the terrace berm and dunes that were lost to erosion through weather of the last years, including hurricanes Matthew and Irma.
“The temporary/emergency sand bags placed at Villas by the Sea and The Cottages at Jekyll Island are proposed to remain in place and be buried under the beach fill as a ‘backstop’ level of protection for extreme storm events in the future,” according to the proposal. “Sand will be placed using trucks or conveyors.”
After construction of the dunes, vegetation planned for the new area would include sea oats, bitter panicum, salt meadow cordgrass and Spanish bayonet. After the plants become established, others may be added, including silverleaf croton, yaupon holly, saw palmetto, tough bully and sand live oak.
Public access paths and crossovers are to go in at the end of Barron, Bliss, Nelson, Tyler, Porter, Ellis, Albright, Stewart, Austin and Gould lanes, along with at the proposed rock revetment return site.
The rock revetment return site is located in the 1,000-foot northern portion of the proposal, near where the Phase One revetment terminates.
More information on the proposal, including drawings, are available at coastalgadnr.org under “Marsh & Shore Permits.” Comments and questions about the proposal can be sent through Oct. 27 to Josh Noble, Department of Natural Resources, One Conservation Way, Brunswick, Ga., 31520.
