Barrier islands are highly vulnerable to relative sea-level rise, erosion, and tropical storms, but simply categorizing their entire extent as a risky place to live would not help guide ongoing urban development. These interactive maps show areas that vary in their susceptibility to, and function for, mitigating the effects of geological processes. These processes include relative sea-level rise, erosion, and storm-surge flooding and washover. Information about geoenvironments, terrain elevation, historical and projected shoreline positions, and parcels is also included.

These interactive maps have been created by the Coastal and Marine Geospatial Lab of the Harte Research Institute for Gulf of Mexico Studies at Texas A&M University-Corpus Christi. Content displayed on the map viewers has been developed using information and funding from various sources.
