The COD-1 District essentially encompasses relatively small or narrow waterbodies and lands immediately adjacent thereto. Because of the small or narrow configuration of these waterbodies, construction of shoreline structures, such as docks, piers, bulkheads, revetments or other major shoreline construction, in areas not previously disturbed by such development (i.e., natural beach, tidal flats, adjacent woodlands or salt marsh) may have a significant adverse impact upon the environment.
