(a) Preferred shore erosion control measures. Vegetation shall be used as a shore erosion control measure unless it is demonstrated to be ineffective. In that event, an alternative measure shall be used in the following order of preference:
(1) vegetation in combination with a stone sill, groin, breakwater, or similar wave dissipating structure;
(2) the establishment or expansion of a beach by placing sand fill between the mean high-water line and mean low-water line;
(3) riprap and materials similar to riprap that are composed of loose, permeable components; or
(4) a bulkhead, groin, jetty, revetment, or seawall if the erosion rate is greater than two feet per year or when site constraints, such as water depth or topography, make other measures impractical.
(b) Structures parallel to shoreline. Shore erosion control structures built parallel to the shoreline may not extend beyond the natural shoreline at mean high water except to achieve a stable slope behind the structure.
(c) Replacement of damaged bulkheads and seawalls. Existing damaged bulkheads and seawalls may be replaced with a new structure within 18 inches of the old structure.
