Recent projects include the Tamalpais Lands Collaborative (TLC), a new public-private partnership that will bring together the resources, skills, and philanthropy of the National Park Service, California State Parks, Marin Municipal Water District, Marin County Parks, and the Parks Conservancy to support conservation, stewardship, and public enjoyment of the Mount Tamalpais region in Marin County, California. The Parks Conservancy is also collaborating with the Presidio Trust and the NPS on the New Presidio Parklands Project, that will create 10 acres of new national parkland in the Presidio of San Francisco, bridging the new Presidio Parkway tunnel that connects the Golden Gate Bridge to the city street grid.
