Here are the costs:

Allowing sea walls at inlets would lift the state's ban on hardened coastal structures. Oregon is the only other state with such a ban. A study sponsored by the Coastal Resources Commission put the cost of building the sea walls at $3.4 million to $10 million depending on their size, with added maintenance and monitoring costs of more than $2 million a year.

Someone ought to estimate the benefits.
