1. Time Series for the east end of Raccoon Island of the Isles Dernieres 1984 - 2007 Aerial Video Survey Program Pontchartrain Institute of Environmental Sciences University of New Orleans Karen A Westphal

2. The Aerial Video Survey Program has been acquiring photography and video of the northern Gulf of Mexico shoreline since 1984. Oblique aerial photography does not produce exact matches due to variations in altitude, camera angle and distance from the shore (and different photographers). Photos that matched well were scaled and aligned to illustrate the landscape changes that have taken place between time periods. Occasionally a pointer or symbol was added to assist with the visual comparison.

25. Relevant Coastal Restoration Projects  Raccoon Island Repair. State Project Number: RI Project Priority List (PPL): N/A Project Type: Beneficial Use of Dredged Material Construction Completion Date 1994 Description: This project was a cooperative effort that utilized dredged material and vegetation to repair Raccoon Island from storm damage. Cooperators include the Louisiana Department of Natural Resources (LDNR)/ Coastal Restoration Division (CRD), Louisiana Department of Wildlife and Fisheries (LDWF)/Fur and Refuge Division, Terrebonne Parish Consolidated Government (TPCG), South Terrebonne Tidewater Management and Conservation District, T. Baker Smith & Son, Inc., Coastal Engineering & Environmental Consultants, Inc., and Bean Dredging. Federal grant money was also utilized for this project by LDWF and TPCG.  Raccoon Island Breakwaters Demonstration. State Project Number TE-29 Project Priority List (PPL): 05 Federal Sponsor: Natural Resources Conservation Service (NRCS) Project Type: Barrier Island Construction Completion Date 1997 Description: This demonstration project's goal is to reduce shoreline erosion and increase land coverage. Eight segmented breakwaters were constructed along the eastern end of the island to reduce the rate of shoreline retreat, promote sediment deposition along the beach, and protect seabird habitat. Project effectiveness was determined by monitoring changes in the shoreline, wave energy, and elevations along the beach, and by surveys of the gulf floor between the shoreline and the breakwaters.  Raccoon Island Shoreline Protection/Marsh Creation. State Project Number TE-48 Project Priority List (PPL): 11 Federal Sponsor: Natural Resources Conservation Service (NRCS) Project Types: Shoreline Protection, Marsh Creation Construction Completion Date Pending Description: The goal of this project is to protect the Raccoon Island rookery and seabird colonies from an encroaching shoreline by reducing the rate of erosion along the western end of the island and creating more land along the northern shoreline. This goal will be accomplished through the construction of eight additional segmented breakwaters and a terminal groin along the gulf side of the island, adjacent to the Raccoon Island Breakwaters Demonstration (TE-29) project. In addition, dredged material will be used to create marsh on the bay side of the island. http://dnr.louisiana.gov/crm/coastres/projectlist.asp  Raccoon Island Repair.
