The present state of Puget Sound’s shore is the sum of myriad small biologic and physical disasters across several millennia. Beaches and their biota have washed away, waves and currents have etched the banks, backshores have collapsed, burying intertidal habitats and carrying upshore habitats to oblivion. Every shoreline reach has been pummeled.

Of the nine concerns eight appear to be resolved by current rules and practice that put shore protection tightly against banks.
