§ 196A-12. Coastal Erosion

C. Coastal banks significant to storm damage prevention and flood control as vertical buffers and as sources of sediment to coastal beaches, dunes and barrier beaches

Where a coastal bank is significant to storm damage prevention and flood control, both because it is a vertical buffer to stormwaters and because it supplies sediment to coastal beaches, dunes, or barrier beaches, no new bulkhead, revetment, seawall, groin, or other Coastal Engineering Structure shall be permitted on such coastal bank except that the Orleans Conservation Commission has the discretion to permit such structure if, in its judgment, such structure is required - and there is no reasonable alternative method of protection - to prevent storm damage to buildings constructed prior to August 10, 1978 [see 310 CMR 10.30(3)] and buildings reconstructed subsequent to that date but prior to the adoption of these regulations, unless the Orders of Conditions under which such reconstruction was performed contain a prohibition against construction of such a structure including but not limited to bulkhead, revetment or seawall.
