CPE will document beach nourishment projects constructed , including the Sector 3 project constructed <br /> from May 2010 through March 2012 . <br /> CPE will develop a sediment budget and alongshore transport rate for the entire length of the County . <br /> Net sediment transport rates at the north end of the County ( Sebastian Inlet) will be based <br /> upon <br /> literature . CPE will evaluate whether diffusion from beach nourishment projects will need to be <br /> removed from the longshore transport analysis in order to determine longshore transport due to wave <br /> driven transport . A comparison of the longshore transport rates determined from this analytic analysis <br /> of volumetric changes will be compared to numerically modeled longshore transport , discussed later in <br /> this scope . <br /> CPE will incorporate environmental data from monitoring reports developed following the 2008 BPP . <br /> This is expected to primarily include monitoring of the Sector 3 Beach and Dune Restoration project. <br /> Task 2 : Public Meetings <br /> Following an update of the beach conditions , CPE will hold a public meeting/ planning charette in Vero <br /> Beach to explain the goals and objectives of update to the BPP and to solicit public input into potential <br /> beach management strategies . A summary of public comments will be included in the BPP . <br /> A second public meeting will be held following development of the beach management strategies and <br /> completion of the strategy modeling . <br /> Task 3 : Sector Boundaries and Beach Management Strategies <br /> CPE will review the boundaries of the various Sectors ( 1 through 8) within the County . The delineation <br /> of these sectors will be evaluated with respect to dominant coastal processes , historical shoreline <br /> changes , projected bluff location in 30 years , upland development , and environmental resources . The <br /> boundaries will be left as is for consistency purposes unless there is a significant need to change them , <br /> such as a different beach management strategy being employed within the sector . <br /> Various beach management strategies will be evaluated for each sector. This may include but not be <br /> limited to no action , beach restoration , dune restoration , coastal structures , and sand bypassing . <br /> Regulatory and environmental constraints associated with the various strategies will be considered . A <br /> generalized strategy will be recommended for each section . <br /> While all sectors will be evaluated , it is anticipated that Sectors 3 , 5 and 7 will be the <br /> areas that will <br /> require greater focus with respect to management strategies , based on the previous Beach <br /> Preservation Plan and a review of ongoing efforts . We will develop preliminary alternatives to assess a <br /> given strategy , such as examining the dune or beach nourishment volume required to provide a given <br /> level of protection and how that would affect nearshore hardbottom . We will also provide an initial <br /> analysis of potential structural solutions , including groins , permeable adjustable groins , T- head groins , <br /> breakwaters , seawalls , revetments , submerged reefs and PEP reefs . During the scoping meeting for <br /> the BPP , the effectiveness of the PEP reefs was discussed . Special consideration will be given to the <br /> evaluation of the PEP reefs using the latest available data . <br />
