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 5 : 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 DeIft31D- FLOW.
