One option would be to prohibit building homes so close to the beach; this would mean that fewer buildings would be vulnerable to hurricane-driven waves. Another option would be to build seawalls that would absorb wave energy rather than allowing the waves to sweep across the barrier island (although this would erode away the beach on the seaward side of the seawall). Also, the beach could be made wider, by either adding sand to the beach or by constructing groins that would capture sediment transported by longshore currents.
