These planning initiatives recommended sand placement activities in <br />all or part of five (5) of the eight (8) planning sectors which encompass the <br />County's 22 -mile shoreline. A secondary goal which will be derived from <br />providing storm damage protection and the reinstatement of sand bypassing is <br />recreational enhancement of the beach. <br />The principal means of maintaining the beaches, which is economically and <br />environmentally feasible, is beach restoration and subsequent renourishments. <br />Beach restoration involves identifying a suitable source of borrow sand, and <br />transf-erring Thai sand GV the shoreilnu to create an additionai beach width and <br />height at an elevation suitable to protect the upland property and infrastructure <br />from a moderate to severe storm event. <br />Given that the shoreline restoration alone does not eliminate the erosion problem <br />which predicated the activity, the beach will continue to erode until a <br />rnnint�nnnr+aewexn+,nr "rcnni.rie I—ent" of thoohomlina via.TL <br />. . 11 n <br />1 ha debufi ievei <br />of storm protection for the beach restoration projects should enable the shoreline <br />to incur damages from a 15 year return interval storm (with a 5 year return <br />interval along Sector 7, excluding the stabilizing influencing of the proposed <br />structures) at any time between the initial restoration and subsequent <br />renourishments. <br />FB OMPHS2REPORPMW VOAWKME <br />31 <br />
