Dauphin Island, Alabama, as a part of the northern Gulf of America's barrier island system, provides protection to a large portion of the state’s coastal resources and approximately one-third of Mississippi Sound. The island has experienced historical beach and back-barrier marsh erosion driven by climatic and anthropogenic events which threaten the ecological services and protection provided by Dauphin Island. Graveline Bay, on the back-barrier side of Dauphin Island, has experienced approximately 75 acres of marsh erosion over the last 170 years. The National Fish and Wildlife Foundation Gulf Environmental Benefit Fund funded the construction of the Graveline Bay Marsh Restoration Project to remedy harm to injured natural resources from the Deepwater Horizon oil spill. Completed in the spring of 2023, the project restored approximately 60 acres of inter-tidal back-barrier marsh habitat through the design and construction of marsh mounds, maximizing the linear footage of highly productive marsh edge habitat. Additionally, nearby homeowners have experienced secondary benefits from the sheltered wave climate during high water level events. This reduction in flood risk is being studied by The Water Institute’s Gulf Center for Equitable Climate Resilience to understand how the change in flood risk impacts actuarial risk rating with the goal to inform FEMA’s Risk Rating 2.0 for the residents around this Bay. This pilot project scope included numerical modeling to inform potential wave height and total water level impacts to sheltered properties; engaging residents to assess type and frequency of flood insurance; education on FEMA’s new Risk Rating 2.0 and the goals of the project; assessment of risk reduction; and generation of content for each homeowner with change in flood frequencies and corresponding reduction in actuarial risk; supporting residents to share results with insurance agencies; and tracking of road blocks to see if this project lowers premiums.
