Description | Project consists of placement of beach compatible material along 16 miles coastline in Brevard County Florida. The project is broken into three segments: Patrick Air Force Base (PAFB), Mid-Reach, and South-Reach with a total combine yardage for all three projects is approximately 1.14 million cubic yards. PAFB is a 3.7 mile long project between monuments R-55 and R-75.4 placing a total volume of approximately 350,000 CY from Canaveral Shoals II offshore borrow area. PAFB project is split between two segments. The northern 1.9 mile PAFB segment (R-55 to R-65) will hydraulically place approximately 235,000 cubic yards (CY) by conventional hydraulic placement with an average fill density of 25 CY /linear feet (LF). Hydraulic placement south of R-65 to R-75.4 cannot occur due to the presence of emergent nearshore rock outcrops. Therefore, a stockpile area on the beach is provided between R-61 to R-65 which can be hydraulically stockpiled with up to 90,000 CY. The stored material can then be mechanically transferred via truck haul on the beach or A1A to place approximately 115,000 CY as beach and dune fill between R-65 and R-75.4. The Mid-Reach project is a 7.8 mile small-scale beach fill project which begins at the south end of Patrick Air Force Base, approximately 16 miles south of Cape Canaveral, and spans 7.8 miles of shoreline between Monuments R-75.4 and R118.3 ending just north of the Town of Indialantic. The volume to place is approximately 280,000 CY with an expected fill density between 2 to 10 CY/FT. Hydraulic placement within Mid-Reach is prohibited. Beach quality sediment can be attained from a South Reach beach stock pile constructed for the purpose. The south reach stockpile area is approximately 8 miles south of the Mid-Reach placement site with a maximum and minimum distance of 11.6 miles and 4 miles, respectively. The stockpile area can be hydraulically filled and then mechanically transferred to the placement area along Highway A1A only. Once delivered to the Mid Reach sand will be offloaded at construction access/staging areas before being distributed by off road dump truck. A residual beach fill of approximately 65,000 CY (above the 280,000 CY mid reach volume) will be left within the stockpile area at the south end of the South Reach after the truck haul is completed. Stockpile geometry and approximate volume is shown in the attached drawings. Up to 80,000 CY for the Mid Reach beach fill may be obtained from upland sand sources containing beach quality sand meeting Corps specifications. The South Reach is a 3.8 mile long project between R-monuments 118.3 and R-139. The South Reach can be constructed using conventional hydraulic placement via hopper dredge. The South Reach fill quantity is expected to be approximately 465,000 CY with an average fill density of 22.3 CY/LF that ranges between 12 CY/LF to 37 CY/LF. The borrow source for PAFB, South Reach, and the South Reach Stockpile area is Canaveral Shoals II. The Canaveral Shoals II Borrow Area is located east of Cape Canaveral, and is centered approximately 4.5 miles offshore of Cape Canaveral Air Force Station (CCAFS) and 8 miles from Port Canaveral. Project Location Brevard County is located on Florida's central east coast bordering the Atlantic Ocean just south of Cape Canaveral. The Brevard County shoreline is a barrier island approximately 72 miles long separated from the mainland by the Mosquito Lagoon and Banana River to the north and the Indian River Lagoon, and extends the length of the county. Access to the Atlantic Ocean is provided at Cape Canaveral to the north and Sebastian Inlet to the south. | ||||||
