Highlights
This project was achieved through the efforts of concerned citizens as well as the Trust for Public Land and other entities. Cowell Ranch/John Marsh is one of California’s newest state parks, although currently not open to the public. Portions of the masonry structure were on the verge of collapse when California State Parks prepared and issued a partial stabilization repair scheme and bid package.
