(ow A conceptual layout will be based on analytic analyses and equilibrium shoreline locations. An initial cost and annual cost for these potential structural solutions will be developed. A discussion of permitting considerations including hardbottom coverage and potential downdrift impacts and expected permitting effort will be included. This more detailed discussion of potential structural solutions will be included as an appendix in the BPP. A summary of the discussion on coastal structures will be included in the main body of the Plan. The preferred alternatives will be carried forward into the coastal modeling effort. Any beach fill strategies will require fill to execute the strategy. A discussion of upland and sources and offshore borrow areas will be included in the BPP based on available literature and previous field investigations. No additional field work is proposed. CPE will present the interim findings of the beach management strategy to the Indian River County Beach Commission. Feedback from this meeting will be incorporated into the BPP. Task 4: Public Access Inventory CPE will include an updated inventory of existing public beach access within the County. The public access points will be described with respect to whether they are primary or secondary access points as defined by the FDEP. The length of shoreline eligible for cost sharing by the State will also be updated. CPE will coordinate with the County to determine whether there have been changes to the 2008 public access inventory. No field verification of the number of parking spaces is proposed as part of this work. If verification of the number of parking spaces is required, CPE will rely on the County to provide this data. CPE will inform the County if a site visit is specifically required to document public access conditions. An assessment of beach access improvements will be performed. Recommendations will be developed based on the cost effectiveness of improving the beach access in order to obtain additional State funding. These recommendations will partially be based on the recommended strategy for a given beach sector. Task 6: Coastal Modeling -DeIft3D Alternatives Analysis CPE will develop a three dimensional DeIft3D model that extends the length of Indian River County. DeIft3D can model the complex interactions between offshore bathymetry, waves, tides, winds, currents, sediment transport, erosion and deposition. The model will be used to determine longshore transport rates and if there are localized areas of wave focusing. As such, the model will assist in the analysis of coastal processes and the development of specific beach management strategies. Waves in DeIft3D are simulated using SWAN (Simulating Waves Nearshore), an advanced wave transformation model that incorporates most wave transformation processes, including breaking, shoaling, refraction, diffraction, and bottom friction. SWAN will transform waves from deepwater to nearshore. Water levels, currents, sediment transport and bathymetric changes will be simulated using DeIft3D-FLOW. 32
