Boat ramps are notorious for acting like groins and for paving over viable beach habitat. It's hard to bury one's eggs in concrete. So in several places on the Sound, new ramps have been built like this, bridging over the beach. Others can be found in Allyn, Silverdale, and a few other spots. Like any bridging structure or pier, they can trap drift logs and then they begin to act like groins - which means some maintenance is required. It also seems to matter how they are oriented. If wave action is oblique, it is more likely to transport sediment under and past the structure. But if wave action is more normal to the beach, sediment tends to accumulate beneath the structure, which shouldn't be a surprise, but sort of defeats the purpose of allowing unimpeded sediment transport.
I like this little park - it's got great views across the Sound at our local metropolis. The edge of the lawn is a little ragged, as it is built on fill and the waves want to nibble way at it, but generally it is doing fine. This is a nice little sandy beach - at least by the coarse standard of this region.
