Attorney George Nickerson, of Nabors, Giblin & Nickerson, P.A., reviewed some of the methods of paying for the project: 4.0 PROJECT COSTS 4.1 PROJECT DESCRIPTION The BPP shore protection project initiatives are intended to provide protection to the barrier island shoreline from moderate storm damage, and to mitigate the historical adverse effects of the inlet on the downdrift oceanfront properties. The planning initiatives identified in the BPP revealed sand placement activities in all or part of five (5) of the eight (8) planning sectors which encompass the County's 22 -mile shoreline. A secondary goal which will be derived from providing storm damage protection and reinstatement of sand bypassing along the Indian River County shoreline is recreational enhancement of the beach. The principal means of maintaining the island's beaches which is economically and environmentally feasible is beach restoration and subsequent renourishment. Beach restoration involves identifying a suitable source of borrow sand, typically found offshore of the project shoreline, and transferring that sand to the shoreline to create an additional beach width and height at an elevation suitable to protect the upland property and infrastructure from a moderate to severe storm event. Material pumped to shore from conventional dredging equipment is placed and graded above the waterline at construction, with a seaward slope of the fill established by earthmoving equipment to tie into, or 'toe' in to the pre -construction beach at some elevation below the practical limits of equipment movement. Those segments of the artificially created beach above the slope break, or berm, are graded to a final elevation and occasionally planted with dune vegetation at the landward limits of the new berm. Upon completion-pf the fill project, the shoreline is then subjected to a period of adjustment as waves and currents work the artificial perturbation in the shoreline (when compared with pre -construction conditions) into a quasi -stable, or "equilibrium° configuration. Given that the shoreline restoration alone does not eliminate the erosion problem which predicated the activity, the beach will continue to erode until a maintenance event, or °renourishment" of the shoreline occurs. The targeted level of storm protection for all beach restoration projects on the Island should enable any individually considered shoreline restoration segment to incur damages from a 15 year return interval storm at any time between the initial restoration (first time sand is placed on the shoreline) and subsequent renourishments (regular maintenance interval of sand placement to restore the shoreline to its initial restoration position).
