JAN 16 1935 BOOK 59, F,1j1= 4_64 To protect the work that we have done, we now need to do considerable dune restoration to protect our existing structures. Should we have another storm similar to the one we had within the next twelve months, I believe we would lose the eight structures we have repaired. If this occurred, it would be necessary to close Wabasso Park, Tracking Station Park, and the two Beach Crossover Parks. Currently some sand has begun to rebuild on the beach, but not at the scarp of the dune. I have had considerable conversation with Barry Manson -Hing, Clinton Taylor, and Lonnie Ryder of the Beaches and Shores Section of the Department of Natural Resources with respect to this matter. Mr. Manson -Hing, the Chief Coastal Engineer, has made the following recommendation for our four park locations. We are not allowed to scrape (bulldoze) sand from the beach as it is their opinion that this method is self-defeating in the long run. Because of this, we will need to transport sand from off-site. I have been in contact with the Sebastian Inlet Taxing District (Rene Van de Voorde, Attorney) and I am hopeful that they will furnish us with the necessary sand from their Inlet dredging project. Because of the nature of our beach accesses, it will be necessary to transfer the sand from the trucks to the dunes by dragline. I have obtained an emergency permit to do this from the Department of Natural Resources, as well as to put a front-end loader on the beach to put the sand in the proper places. We would try to extend our dunes on a 450 angle so that we could then revegetate the foredunes with appropriate plant material. It is my opinion that, because our dunes were well vegetated when we had the last storm, that is why we did not lose our dune crossovers. The best estimate of cost that I can make at this time is between $50,000 to $65,000, depending on whether or not we are able to obtain the sand from the Sebastian Inlet District. Much of the work can be done in-house if so authorized by the Board. Should we lose these eight crossovers, I would estimate the contract cost of replacing them at today's cost would be $80,000. This figure would not include any in-house engineering or dune restoration. I have gone over this matter with Art Challacombe, Planning Department, and Don Finney, Engineering Department. They have endorsed this solution; therefore, I recommend that the Board of County Commissioners approve this project. Director Thomas reported that Don Finney, of the County Engineering Department, has given him a figure of approximately 4,000 cubic yards of sand, and he emphasized that this sand is for dune restoration, not beach renourishment. Director Thomas stated that if the Board approves, proceeding in this manner, they would obtain more exact figures and come back regarding funding. 10 M
