r annual erosion rates, and anticipated storm recession for a 15 -year design storm. The average annual erosion rates over the past 11 years were computed along the project sectors, based on the period of 198E to 1997. Table 1 presents a summary of the characteristics of properties that front the beach nourishment projects identified in the BPP and depicted in Figures 2 and 3. 2.2 CALCULATION OF STORM PROTECTION BENEFITS The storm protection benefit received by an individual property, within an identified project Area, is the expected reduction in land loss due to erosion and the associated cost of tate land protected and the cost to build an erosion control structure for storm protection or the costs of maintaining or repairing an existing erasion control structure in the absence of the project. In the case of oceanfront homes, and properties with upland improvements such as pools and cabanas, which are not presently ,protected by a hardened structure (such as a seawall or revetment) the distance from the mean high water line to the most seaward structure was compared with tate expected erosion rates over 8 years and the storm recession distance for a 15 year return period storm event, except for Sector 7 where the storm recession distance for a five (5) -year return period storm event and eight (8) years of erosion were applied. The expected loss consists of tate discounted stream of future losses over a 30 - year period. The extent of loss varies by reacts of shoreline according to the erosion rates. Losses also consider land values, beach widths and distances between buildings and the mean high water line. The dune erosion model EDUNE was evaluated at four (4) beach profile locations on the Island, at the locations shown in Table 2 based on established Florida Department of Environmental Protection (FDEP) monuments.
