Erosion can be managed and we can build seawalls. But unless the public owns any land reclaimed, its a bad investment. Residential owners are the worse. They build retaining walls and fences on the beach. The law should clearly state that is illegal.

There is a law IIRC that any land 50 feet from the stream belongs to the state. It should be extend to the shoreline as well. How about this? Any land 50 feet from the water level. Any man made structures at water level must be demolished?

When the sea walls go up this will also apply to surveyed water level line. When ocean levels rise people will lose out but perhaps this will give additional incentive to do something about the problem.
