Which risk increases when new housing restricts barrier island migration?

💡 Explanation

Decreased barrier island migration reduces width of sandy beach and dune buffer causing larger storm surges; wave energy dissipation lessens during storm events because reduced buffer, therefore increased flooding and damage occurs, rather than lessened storm-wave energy.
