Caminada Headland Beach and Dune Restoration (BA-45) Brad Miller Louisiana Coastal Protection and Restoration Authority committed to our coast

 2004 LCA Barrier Island Feasibility Study Louisiana Coastal Area Study (LCA) identified Caminada Headland as a near-term critical project. Chiefs Report Signed June 2012  CIAP / State Surplus of 2008 Coastal Impact Assistance Program (CIAP) $30M State Surplus, $40M CIAP Project Origin Coastal Protection and Restoration Authority

Project Setting

Coastal Protection and Restoration Authority Purpose  The goal of the Project is to protect and preserve the structural integrity of the barrier shoreline of the Caminada Headland by: Protecting and sustaining significant and unique coastal habitats. Protect threatened and endangered species. Reducing wave energy and salt-water intrusion from the Gulf of Mexico into back-barrier environments, including chenier ridges, marshes, and mangrove wetlands. Providing a sediment source to sustain barrier beaches east and west of the Headland.  Maintain and restore the integrity of the Louisiana coastline.  Address severe erosion of Headland (historical average of 45 ft per year)  Incidental benefits include protection of Port Fourchon.

Former site of the mouth of the Mississippi River Approx. 14 miles long Consists of narrow, low lying sand dune and beach berm, barrier marshes and chenier ridges Shoreline erosion rate of 45 feet per year No other Louisiana headland remains attached to the distributary that formed it.

South Pelto Borrow Area Coastal Protection and Restoration Authority

Ship Shoal Coastal Protection and Restoration Authority Ship Shoal is associated with barrier islands that were reworked remnants of the Maringouin delta complex of the Mississippi River Approximately 8,000 years old This is the 1st project ever to use offshore shoal sands in the gulf for beach and dune restoration Ship Shoal is estimated to contain 900 million cubic yards of sand and encompasses approx. 76,600 acres

Coastal Protection and Restoration Authority Ship Shoal– Prior Work Shea Penland advocates for use of Ship Shoal sand for shoreline restoration based on MMS-LGS cooperative study on OCS sand resources (Penland et al., 1988, 1989) Extensive geophysical and archaeological studies undertaken in 2003 (C&C, 2003) Nine Vibracore samples collected by Coastal Planning and Engineering (Finkl, et al., 2005) Area contains very clean sand ranging in thickness and grain size from 13 to 20 feet and 0.15 to 0.20mm, respectively (Khalil et al. 2007)

Coastal Protection and Restoration Authority Ship Shoal– New Work Detailed Cultural Resources Survey by Ocean Surveys, Inc., approx. 1,500 acres (June 2011) Subbottom data indicated a sand thickness of 11 to 18 feet Magnetometer and sidescan data indicate the sand body is free of significant targets / anomalies Thirteen 20-foot long vibracores completed for ground truthing ~ excellent recovery: 15 to 19 feet of sand

Coastal Protection and Restoration Authority Lessons Learned Turtles What Turtles?

Coastal Protection and Restoration Authority Total Allowable Take for Turtles to be Relocated Bi-Annually was 76 Turtle Trawling began in May th Turtle Relocated on June 7, 2014… NMFS Allowed Trawling to continue and in total there were 157 relocations for this project, including 79 ridleys, 76 loggerheads and 2 greens. No turtles were harmed during relocation trawling activities. Some of the highest numbers of mature male turtles ever tagged and released! Opportunities for future partnerships to satellite tag turtles. Constant Communication with Regulatory Agencies is Essential! Lessons Learned
