Fill was placed between Florida Department of Environmental Protection (FDEP) <br /> (W Monuments R-55 and R-20. <br /> Following construction of Sector 3, the region was impacted by Hurricane Sandy in October 2012. The Sector 3 <br /> project area sustained damaged and is in need of repair to maintain protection to upland properties and infrastructure <br /> during future storm events. The proposed Sector 3 Beach and Dune Restoration Repair Project is eligible for 50% <br /> State cost share and is included in the State approved budget for FY 2013/14. This proposal outlines the scope of <br /> work to design and permit the repair of the Sector 3 project area damaged as a result of Hurricane Sandy. <br /> Preliminary Project Design and Feasibility Report <br /> In the initial phase of the design, available information will be evaluated in the development of the project size. The <br /> intent is to utilize.available beach survey data from the County's most recent monitoring event (scheduled for July <br /> 2013) as the preliminary design survey to aid in the initial design and permitting effort. The design template <br /> constructed in 2010-2012 will be used as the basis of the design. The July 2013 surveys will be analyzed to estimate <br /> the volume of material required to reconstruct the dune and berm lost to Hurricane Sandy. In particular, the <br /> placement of fill landward of the mean high water line (MHW) will be considered to limit potential impacts to <br /> hardbottom resources and expedite the permitting process. <br /> A feasibility analysis will be performed to evaluate potential sand borrow sources to be utilized for fill material. The <br /> analysis will evaluate various upland sand sources and offshore borrow areas to identify the most economical and cost <br /> effective option. The upland sand sources,including Ranch Road Lake and Fischer 86th mines,will be considered as <br /> they have been previously approved by the FDEP under the County's sea turtle test plan for grain size, color, and <br /> density. <br /> (W <br /> 2481 NW BOCA RATON BOULEVARD, BOCA RATON, FL 33431 <br /> 561.391.8102 • FAX 561.391.9116 • COASTAL PLANNING & ENGINEERING, INC., A CB&I COMPANY 84 <br />
