The one exception was a small beach that had formed where the ragged edge of the peninsula happened to offer an appropriate configuration. But this actually provides a very nice template for future work - since it shows what orientation, what sediment size, and what beach and berm profile works best. The best model for a created beach is the beach next door!

A couple of years ago the city began resculpting the edge and created a pocket beach. They improved the rock work at a couple of small promontories, excavated the rock and fill between them, and added gravel. Orientation is key on these pocket beaches and this one may still be adjusting. The mobile sand and gravel is wanting to stay in the northeastern half of the little cove, leaving the western end a steeper slope of coarse cobble and rock, but it looks like overall the project has worked out well.
This project was limited to just one segment of shoreline, but it sounds like there's interest in extending this approach to additional segments in the future. You still need rocky hard points to anchor and contain the beaches, but the rock need not be old construction debris. And most of the shoreline can be a series of small beaches.
