Because of the many problems with flood and erosion control structures, there has been a shift in recent years toward non-structural shore stabilization techniques. Non-structural shore protection measures generally seek to enhance the natural ability of shorelines to absorb and dissipate storm energy without interfering with natural beach, dune, and bank processes.
Some non-structural shore protection techniques to consider include:
- Renourishing beaches and dunes. See NOAA’s Beach Nourishment: A Guide for Local Officials website, which includes sections on sediment budgets and identifying sources of sand.
- Stabilizing dunes with fences and vegetation. Mississippi-Alabama Sea Grant offers guidance on shoreline stabilization policies for Mississippi, Alabama, and Florida with their publication Focus On: Living Shorelines (PDF, 620KB).
- Protecting, nourishing, or constructing dunes.
- Re-vegetating/stabilizing shorelines and/or riparian (river) corridors with native plants.
- Creating or restoring wetlands. The Mobile Bay National Estuary Program offers a database search of various restoration projects done in Mississippi and Alabama.
- Prohibiting or more stringently restricting the infill of wetlands.

Notes from the folks at CRS:
“CRS credits programs that maintain measures that protect buildings from coastal flooding or erosion. These include dune and mangrove preservation, bluff stabilization, and beach nourishment programs.”
