Caminada Headland Beach and Dune Restoration (BA-45)

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

2. Project Origin • 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 Coastal Protection and Restoration Authority

3. Project Setting

4. 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. Coastal Protection and Restoration Authority

5. Caminada Headland • 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.

7. Ship Shoal • 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

8. 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

9. 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

Project Timeline/Lessons Learned… • August 2013 Pumping of Sediment Begins • January 2014 Contractor Voluntarily Demobilizes for the Winter • May 2014 Pumping Scheduled to Resume, BUT….. tweet tweet • Late May 2014 Pumping Resumes on Eastern Portion of Project with Hopper Dredges • September 2014 Both Belle Pass Unloader and Hoppers are working • December 2014 Project is Substantially Complete Coastal Protection and Restoration Authority

28. Lessons Learned • Routine bird monitoring can aid in effective bird abatement (sometimes….) BTNEP – Preliminary Data • East Beach Bayou 2013 626 86 2014 537 40 East Beach Mid-June/July 107 /5 chicks (3 minute obs time) Most OBS/Most Success Coastal Protection and Restoration Authority

29. Lessons Learned • Routine bird monitoring can aid in effective bird abatement (sometimes….) Pumping stopped Jan. 2014 Least Tern Colony Pumping resumed May 2014 Coastal Protection and Restoration Authority

30. Lessons Learned • Routine bird monitoring can aid in effective bird abatement (sometimes….) • Colony nearest Construction most successful! • Human presence reduces predation? • Travel corridor has little impact on birds • Abatement West Beach affected nest success • Abatement strictly to maintain access • Abatement Methods • Flagging • Harrassment (Vehicle/Fencing) • Furrowing • Constant Communication with Regulatory Agencies is Essential!

31. Lessons Learned Turtles What Turtles? Coastal Protection and Restoration Authority

32. Lessons Learned Total Allowable Take for Turtles to be Relocated Bi-Annually was 76 Turtle Trawling began in May 2014 76th 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! Coastal Protection and Restoration Authority
