Thanks. The water district of isolated “islands” of land inside a bigger open space can be a pain in the neck. Over at Sunol, the water company still owns land within the Sunol Wilderness and you need to get a permit from them to hike across their land — even when you have a permit from the Sunol Wilderness / EBRPD!
This was interesting...”Peninsula Open Space Trust (POST) stepped in and purchased the land, later selling it to the district once they obtained grant funding.” POST effectively loaned the money to get early land acquisition then sold it to the district.
That’s mainly what POST does. Buy land and spin it of into parks and open spaces.
