Because each site is unique, it is not possible to establish a matrix to <br /> identify the appropriate protection measure for all possible scenarios. The Coastal <br /> Engineer will use his/her best professional judgment when deciding the most <br /> appropriate shoreline protection measure for a specific site. This assessment will be <br /> based upon careful consideration of factors such as: <br /> a. Potential for physical damage to the structure because of erosion; <br /> b. Extent of storm damage to the beach/dune system; <br /> c. Distance of the structure from the dune escarpment; <br /> d. Pre-storm conditions at the site (i.e., critically eroding, eroding, accreting, <br /> etc.) ; <br /> e . Potential consequences to coastal processes and downdraft properties <br /> resulting from various shoreline protection options; <br /> f. Time of year when the emergency occurs (e.g. , during or outside of the <br /> nesting season, likelihood for additional storm activity, etc.) ; and <br /> g. Construction schedules for permitted beach nourishment projects at the <br /> site. <br /> 7. Any fill material placed on the beach shall be sand that is similar, an both coloration <br /> and grain-size, to that already existing at natural (i.e. , never before nourished) beach <br /> sites in the County. All such fill material shall be free of construction debris, rocks, <br /> or other foreign material and shall not contain, on average, greater than 10 percent <br /> silts and clays (i.e. , sediments passing through a No . 200 standard sieve) and/or <br /> greater than 5 percent coarse gravel or cobbles (sediments retained by a No . 4 <br /> standard sieve), exclusive of shell material. <br /> 8 . All protective measures shall beimplemented in a manner that minimizes adverse <br /> impacts to the coastal system, native vegetation and adjacent properties, while still <br /> providing adequate protection for the vulnerable structure. If a temporary structure is <br /> permitted, it shall be sited at or landward of the dune escarpment and as close to the <br /> vulnerable structure as practicable to provide sufficient protection. The Coastal <br /> Engineer shall use his/her best professional judgment in determining the appropriate <br /> location of protective structures. Information that will influence the location <br /> includes: <br /> a. The type of protective material(s) to be used, . <br /> b. Constriction methods, <br /> c. Site topography, <br /> d. Distance between the vulnerable structure and dune escarpment, <br /> e. Extent of erosional threat to the vulnerable structure, <br /> f. Presence/absence of sea turtle nesting habitat and/or marked nests, and <br /> g. Other site-specific conditions. <br /> 9. There shall be no implementation of shoreline protection measures until an <br /> emergency permit is obtained from Indian River County. Written application for an <br /> 4 <br />
