More than one transplanted Floridian has paid $150,000 for a beautiful condominium with a sea view only to learn that, to keep the building from becoming part of the view, considerable additional money must be spent to build and repair seawalls or to pump up new beaches by dredging sand from offshore.

Most of Florida's beachfront property lies on narrow strips of sand called barrier islands, which are low in elevation and subject to flooding during storms and hurricanes. Some of the construction is poor, adding to the problems facing homeowners, most whom came from other parts of the country with little awareness of the hazards of beaches. In Living with the East Florida Shore, Orrin H. Pilkey, Jr., of Duke University, along with his co-authors, has described the varied problems that confront the east shore of Florida today.
