5 Shoreline Loss 1999 Post Floyd Lost 15m of Shoreline Never re-established

7 Hurricane Season 2004 KSC

8 KSC Dune Restoration Efforts Hurricane Francis 2004

9 KSC Dune Restoration Efforts 2005 Emergency Hurricane Recovery Funded Dune Restoration

10 KSC Dune Restoration Efforts 2007 Nor easter sits off coast for 2 weeks Dunes Breached Again

11 2008 Restoration Shuttle Funds Kennedy Space Center Dune Restoration Efforts

12 KSC Dune Restoration Efforts Dune restoration started out as a wildlife issue Breached dunes created lighting disorientations to sea turtles

13 Operation Dark Dune Kennedy Space Center No sand to move so used existing NASA railcars to block lights

14 Tropical Storm Fay 2008 Dune Restoration Efforts

15 Dune Erosion Becomes Infrastructure Issue Kennedy Space Center

16 Dune Vulnerability Team Created Unites States Geological Survey University of Florida Innovative Health Applications Coastal Planning and Engineering United States Air Force 45 th Spacewing

17 KSC Dune Vulnerability Team United States Geological Survey Light Detection and Ranging (LIDAR) topographic survey (2009) Historic dune location, current, and short term future (5-15 years) Areas of risk Shoreline Camera (KSC Surf Cam 2010) Bathymetric survey ( Summer 2010) Prediction of operational impacts LIDAR topo overlay Surf Cam Surf Eagle 4

18 Bathymetric Survey Offshore Cape Canaveral What is offshore that could be altering wave action at LC-39 area?

19 E2S2\DVT Cam.avi KSC Surf Cam Camera runs 10 min/hr/day 1200 images per take Data collected via internet connection Shows parallel sand bars that terminate at LC-39 high erosion area. April 2010 to December 2010

27 Local Geologic Influences Narrow beach very little sand for new dune construction Flat beach nothing for natural processes to build a new dune, sand blows into wetlands Wetlands and swales have more peat more erosive less sand to erode to maintain beach

28 KSC Dune Vulnerability

29 KSC Secondary Dune Project Cooperative effort between NASA and Air Force and Fish and Wildlife Service 750 feet long 85 feet wide 15 feet high 30,000 cubic yards of sand Cape Canaveral Air Force Station 45 th Space Wing providing fill material Completed April 2011

32 Secondary Dune Construction

33 Engineering Perspective There are remediation measures that can be implemented Beach Nourishment, Dune Restoration, Coastal Structures May

34 Engineering Perspective Surveys and geotechnical data already exists Ongoing NASA studies can be utilized Design & Permitting Needs: Feasibility Study to identify Conceptual Design Extensive Beach Survey Data (DVT Team in progress) Environmental Studies Sand Source Investigation Permits & Approvals: FDEP, U.S. Army Corps, FWS, NMFS Plans & Specifications for Construction Entire process will take 3 to 5 years Planning needs to start now to determine best course of action and identify funding
