USA: Army Corps Presents Martin County Shore Project
U.S. Army Corps of Engineers has introduced plans for the Martin County Shore Protection Project, Beach Renourishment 2013, Hutchinson Island, Martin County, Florida.
The proposed project includes beach renourishment along 4 miles of the Atlantic Ocean shoreline commencing south from the northern boundary of Martin County between the FDEP reference monuments R-1 through R-25. The approved historical beach fill template included a 90-foot wide berm at Elevation +6.5 NAVD 88.
The constructed foreshore slope would be 1:10. At the south of the project, the beach tapers to the existing profile at monument R-25. The beach fill design also includes a 65-foot wide dune feature that has a 20-foot wide crest at Elevation +11.0 NAVD 88.
Magnitude of construction is between $5,000,000.00 and $10,000,000.00.
To fill this project will require a hopper dredge or similar equipment to obtain beach quality sand that will come from a borrow site located approximately 6 nautical miles offshore of the northern portion of the project.
Designated pipeline corridors shall be used by the Contractor for access to the beach. This will minimize impact on the marine habitat offshore.
