| Abstract: | In the early 1960's local, State, and Federal officials concluded that the beaches of Duval County and the adjacent buildings and infrastructure faced a serious damage threat from storm generated waves and tides. To combat and reduce this threat, the Jacksonville beaches were renourished as early as 1963. Subsequent to the passage of NEPA in 1969 a Final Environmental Impact Statement (FE IS) was prepared in August 1974 to place 3.3 million cubic yards of sand along 10 miles of Duval County beaches. The authorized project area was renourished in 1980, 1986/87, 1994 and partially in 2003. This most recent nourishment was associated with the large amounts of sand found with the deepening of the Jacksonville Harbor channel. The effort ended prematurely when an excessive amount of shell material was deposited on the beach along with sand. The shell material was subsequently removed from the beach but the beach renourishment was not completed. In 2000 an EA was completed and FONSI signed to excavate beach quality sand from the Buck Island dredge material disposal area. However, for economic reasons that planned effort was never begun. A comprehensive renourishment of the beach has not occurred since 1994. The approved Federal participation in the periodic renourishment of the Duval County shoreline requires that beach fill is placed on the project area when erosional forces have significantly reduced the beach berm, and coastal residences and infrastructure are at risk from storm damage. Accordingly, the current state of the beach requires a complete renourishment to assure protection to coastal residents, buildings and infrastructure. The current project will use the same construction templates as the previous renourishment. Information concerning the specifics of the above mentioned templates as well as justification for the calculated fill volumes can be found in the 1984 General Design Memorandum (GDM) and the 1990 Section 934 Report. It is estimated that the current renourishment project will place approximately 1,500,000 cubic yards of beach compatible material on the project beach. |
