I have been exploring for public beach accesses, especially the ones not in parks, which are much harder to find. As I have kept data on what I have found I have been intending to learn map scripting enough to put them on the map, like my Antarctica landing points on my home page. I took long enough that Google made it easier.
Using Google Maps Engine Light (the non-light version is for pros and costs real money) here is what I have found from the Tulalip Indian Reservation north of Marysville to Brown's Point in NE Tacoma. Click the lollypops for more info. The color coding is the beach walking surface, where n/a is, sad to say, where you cannot get on the beach legally and safely.
