Areas were characterized by dunes 3-5 feet and as high as 8-10 feet in <br />height that eroded during the storm that left a sharp scarp at the base of the remaining <br />dunes. <br />In order to provide reasonable protection of severely eroded higher dunes with a sharp <br />scarp at narrow beaches, we implemented the use of a sill underlying the emergency <br />berm. This sill would improve the sustainability of the emergency berm by being a <br />buffer to the swash zone during high tide such that the toe of the emergency berm will <br />not be immediately washed away. The typical sill has dimensions of 2 feet by 40 feet (in <br />width) and is wider than the emergency berm. The sill volume per linear foot is not <br />included in the berm volume per linear foot. See attached filed notes for further <br />explanation of sill volume computations. <br />Eligible sites include areas where houses are at risk due to low elevation or close <br />proximity to the dune edge, and where areas where parking lots are at risk. The <br />following is a summary of each eligible site. <br />
