Abstract:
Fortunately, simple, economically-viable steps can significantly reduce property damage and loss of life; e.g., for barrier islands the key is to view entire islands as well as adjacent nearshore sea floor and onshore mainland as part of an integrated system. Recognition of active processes is fundamental to defining hazard areas. Then, a process-oriented perspective allows risk-zone identification based on measurable parameters such as erosion rates, flood and overwash zones, zones of potential inlet formation and inlet expansion/migration. A process perspective gives insight into repairing existing damage to the natural environment, e.g., restoring beaches, rebuilding excavated interior dunes, plugging dune gaps, reestablishing maritime forest, curving roads around natural island topography, or putting roads/walkways over rather than through such features. In addition, steps can be taken to augment natural protective capabilities of coastal environments, e.g., planting marsh grass to slow estuarine shoreline erosion, beach replenishment, dune construction, and encouraging forest growth. Planning can avoid hazard enhancement by preserving and restoring coastal environments. Relocation plans for buildings and entire communities can also be planned with foresight.
