There are enough constructed beaches on Puget Sound, and Puget sound is large enough, so that it's easy to lose track of some of them. Including some of the nicest ones. Particularly when they're located a little off the track. This one, which I last visited in October 2010, is located in Manchester, pretty much in front of the Manchester Environmental Lab (EPA and Ecology). It is a secured area, so professional interest is tolerated, but a lunch stop with the kids would be frowned on.
This is a really neat beach. It has a slightly engineered look, particularly the coarse gravel storm berm, but what a great alternative to the rock revetment that might have been built otherwise. Remind me someday to figure out how to draw more attention to these projects!
