Comments

Affected coastal cities continue to deal with hurricane damage mitigation with more wind resistant structures, grading and levies. Land erosion is inevitable and some cities are looking at expensive ocean surge protection gates.

Resort areas continue to replenish beaches, clean up and get ready for tourists. Zoning restrictions go into effect in other areas and flood insurance becomes unsustainable. Coastal areas are vulnerable to land loss due to ocean erosion. Some cities have bought this land for parks.
