  "definition": "Naturally occurring accumulations of sand in ridges or mounds landward of the beach. Human alteration of sand dunes within V Zones is prohibited unless it can be demonstrated that such alteration will not increase potential flood damage.\n\nSand dunes are important first lines of defense against coastal storms and can do much to reduce losses to inland coastal development. It can be assumed that any removal or other alteration of a sand dune will render the dune more susceptible to erosion and increase potential damages to structures behind that dune.\n\nCommunities are advised to prohibit all alterations of sand dunes unless the applicant can submit engineering analyses that demonstrate that flood damages will not be increased prior to issuing any permits.\n\nNational Flood Insurance Program Requirements\n\n• 59.1 - Definition\n\n• 60.3 (e)(7) - Alteration of Sand Dunes and Mangrove Stands",
