Debidue Groins, II
On February 7, 2019, on behalf of the S.C. Coastal Conservation League, SCELP filed a Request for Final Review Conference with the S.C. Department of Health and Environmental Control Board of Directors challenging the agency’s recent permit issued to Debordieu Colony Community Association (DCCA) authorizing the construction of three groins on Debidue Beach. The proposed groin system would be located on the southernmost end of DCCA’s property, with the southernmost groin located on the boundary with Hobcaw Barony, the Baruch Foundation property that is home to the North Inlet-Winyah Bay National Estuarine Research Reserve (“NERR”) in Georgetown County.
The groins were intended to protect a narrow strip of oceanfront houses that were built well-seaward of other oceanfront houses at the southernmost tip of Debordieu Colony. The houses were armored with a partially-failing seawall, which was built parallel to the shoreline. The houses were unwisely built seaward of adjacent houses due to artificial beach accretion that resulted when canals were dredged in the salt marsh and the dredge material was placed onto the beach, in essence extending the shoreline seaward.
Groins are erosion control structures constructed perpendicular to the beach, typically in an effort to protect beachfront houses. Groins work by capturing sand as it moves down the beach through longshore transport; however, in doing so, groins act to deprive the downdrift beaches of sand. The downdrift beaches, in this case, are the beaches that buffer one of the few pristine estuaries left in the United States and one of only 28 NERRs in the country and the pristine North Inlet estuary, where the majority of the waters are classified as Outstanding Resource Waters – the highest water classification in the state. The North Inlet-Winyah Bay NERR is hosted by the University of South Carolina’s Belle W. Baruch Institute for Marine and Coastal Sciences where scientists have been conducting long-term ecological studies on the normal functions of estuaries for decades.
The permit decision authorizing the Debidue groin system was made in violation of applicable statutes, regulations and policies contained in the Coastal Zone Management Act (“CZMA”), S.C. Code Ann. §48-39-10, et seq., OCRM Regulations 30-1, et seq., the Coastal Management Program (“CMP”), and DHEC Regulations 61-101, et seq. Most specifically, the permit was issued in spite of the applicant’s multiple concessions that the permitted project will in fact have downdrift impacts in violation of applicable statutory and regulatory law. The groins will exacerbate erosion downdrift of the project, altering a pristine beach/dune system and harming the marine and wildlife which are dependent upon it. Baruch Foundation, which manages the North Inlet/Winyah Bay NERR also filed a Request for Final Review Conference with the DHEC Board.
As we did in 2011, the last time Debordieu Colony sought to construct a new groin field, we trust we will ultimately succeed in overturning the authorization for this unwise and destructive project.
April 5, 2019 — On behalf of the S.C. Coastal Conservation League, SCELP filed an appeal before the South Carolina Administrative Law Court, urging the court to overturn a permit granted by the state’s Department of Health and Environmental Control to construct three groins on Debidue Beach in Georgetown County.
