The U.S. Army Corps of Engineers (USACE), Charleston District is currently involved in the planning phase of an emergency beach rehabilitation to portions of Myrtle Beach along the Grand Strand of South Carolina. The Myrtle Beach Storm Damage Reduction Project was authorized for construction by Section 101 of the Water Resources Development Act of 1990, Public Law 101-640, dated November 28, 1990 (WRDA 90): “MYRTLE BEACH, SOUTH CAROLINA. The authorized project requires the construction of separate protective beach in three separate reaches, North Myrtle Beach (Reach 1); Myrtle Beach (Reach 2), and Garden City/Surfside Beach (Reach 3).” The City of Myrtle Beach is the non-federal sponsor for Reach 2. Rehabilitation of Reach 2 is needed now to repair damages from Hurricane Irma and Hurricane Matthew, combined with a periodic renourishment, to provide the full authorized level of protection. Food Control and Coastal Emergency (FCCE) funds through Public Law 114-254, Further Continuing and Security Assistant Appropriations Act of 2017, have been authorized for this action.

The proposed action will place approximately 1,100,000 cubic yards of beach-compatible sand from the approved Cane South borrow area located approximately three square miles offshore from Myrtle Beach in state waters, to approximately nine miles of shoreline along Reach 2 (City of Myrtle Beach) from Station 575 to Station 1050. The project is expected to commence from May to November of 2018.

The USACE has prepared a Draft Environmental Assessment (EA) and Draft Finding of No Significant Impact (FONSI) to communicate new environmental information since City of Myrtle Beach (Reach 2) was last renourished as part of the Myrtle Beach Storm Damage Reduction Project in 2007, and to facilitate coordination between the USACE, resource agencies, and the public. The USACE’s preliminary findings are that the proposed action does not have a significant adverse effect on the environment or human health, and thus, does not warrant the preparation of a supplemental Environmental Impact Statement. Links to the Draft EA and Draft FONSI can be found below. They are available for review from January 19, 2018 to February 20, 2018. Questions or comments on the draft documents can be directed to Bethney Ward at (843) 329-8162 or Bethney.P.Ward@usace.army.mil.

The USACE and South Carolina DHEC have also issued a Joint Public Notice related to the South Carolina Coastal Zone Management Program. Comments are being received on the notice until March 20, 2018.

The U.S. Army Corps of Engineers (USACE), Charleston District is currently involved in the planning phase of a beach emergency repair in the Grand Strand (Myrtle Beach) of Horry County, South Carolina. The Myrtle Beach Project was authorized for construction by Section 101 of the Water Resources Development Act of 1990, Public Law 101-640, dated November 28, 1990 (WRDA 90): “MYRTLE BEACH, SOUTH CAROLINA. The authorized project requires the construction of separate protective beach in three separate reaches, North Myrtle Beach (Reach 1), Myrtle Beach (Reach 2), and Garden City/Surfside Beach (Reach 3).” The total project reach is 25.3 miles.

Funding is available for Reach 1 North Myrtle Beach. The proposed project is the restoration of a Federal Coastal Storm Damage Reduction project damaged by recent floods and coastal storm.  The proposed project restores approximately 3.3 miles of shoreline along North Myrtle Beach. Preliminary investigations of the quantity of sand required to rebuild the construction template reveal that about 362,000 cubic yards of sand from the Little River borrow site will be placed along North Myrtle Beach.

USACE has prepared a Supplemental EA to communicate new environmental information and update the coordination between USACE, the public, and resource agencies. The draft EA is available for public review from March 17, 2017 until April 17, 2017. The Draft Supplemental EA and the Draft FONSI are below. If you have any questions or require additional information at this time, please contact Jesse Helton at (843) 329-8145 or by email at jesse.s.helton@usace.army.mil.

Last year, The Corps prepared an EA with a Finding of No Significant Impact (FONSI) for Reach 3 (Garden City/Surfside) of the Myrtle Beach Storm Damage Reduction Project.  The project was anticipated to have been constructed throughout the fall and winter of 2016/2017; however, due to contracting constraints the project construction was postponed.  The Corps now intends to issue a contract for the construction of both Reach 1 and 3 and the same time.  Documentation for Reach 3 is available for reference under the Reach 3 Section of this web page.

Authorized in 1971 and constructed between 1977 and 1981, the Murrells Inlet Navigation Project consists of two jetties, a deposition basin, an entrance channel, two inner channels and a turning basin. The initial project provided for an Entrance Channel 300 feet wide, 10 feet deep and extends 3,900 feet from –12-foot ocean contour.  Inner Channel A is 200 feet wide, 10 feet deep and extends from the entrance channel to the mouth of Main Creek, approximately 2000 feet.  Inner Channel B is 90 feet wide, 8 feet deep and extends to an old Army crash boat dock where it terminates with a turning basin 300 feet long and 150 feet wide.  The Auxiliary Channel is 200 feet wide, 10 feet deep and is approximately 1000 feet long.  The Entrance Channel is stabilized by ocean jetties extending seaward 3,445 feet and 3,319 feet on the north and south sides of the Inlet, respectively (Figure I). The north jetty was constructed with a weir section at the north end to allow for passage of sediment within the littoral drift traveling essentially between the shoreline and the –4-foot contour.  Inside the north jetty is a deposition basin that has the capacity to hold up to 600,000 cubic yards of material.  The project resulted in approximately 1,103,300 cubic yards being initially excavated. 

The project also authorized routine maintenance of the federal channel.  Historically, past maintenance was limited to the entrance channel, the depositional basin, Inner Channel A and the upper reaches of Inner Channel B.  The materials that were excavated with both initial construction and previous maintenance efforts was used to either enhance the storm damage reduction project on Garden City Beach or placed within the intertidal zone of the Huntington Beach State Park, near the terminal end of the South jetty.  The material place on Huntington Beach State Park served to restore shorebird habitat and provide protection for the jetty.  The impacts of the previous maintenance projects are addressed in a 2001 Environmental Assessment completed by the US Army Corps of Engineers.
