Protect coastal buildings and infrastructure through shoreline hardening and/or building elevation and floodproofing. Shoreline hardening (e.g., bulkheads, dikes, riprap, and other engineered shore defense structures) can be damaging to intertidal habitats, erode unarmored shorelines downdrift, and may provide only a short-term option for coastal protection depending on the future rate of sea level rise. However, in some circumstances it may be appropriate to construct or fortify shoreline armoring, such as when there are significant tribal assets at stake that will require time to relocate, when setback levees are constructed to allow the removal of existing shoreline levees, or when approved water dependent uses are at risk. Buildings may also be elevated or otherwise designed to reduce flood damage.
