UT not to highjack this thread but your understanding of the property boundaries of Puget Sound waterfront are not fully correct. The instance you site of a road end is accurate that would be an area of public access between the houses but beach ownership on puget sound varies with each area or housing development. The traditional public right of way was to the mean high tide but decades ago the state took an opportunity to raise some money and allowed some to purchase to low tide or in some cases to the shipping lanes. Therefore there is no single legal standard to approach the beaches here, you actually have to either take the waterfront owner's word or research the titles of each particular beach. It's a mess, and a damn constitutional shame. I fly fish the sound so this is something I have everyday experience with and have researched. It's something we have to protect from happening to our river access rights.
