Marin County is set to begin a $3 million project this summer to overhaul trails and repair environmental damage caused by decades of visitation at one of the country’s few remaining old-growth redwood groves. About half of the project funding is from a California State Parks grant. The project is part of the One Tam collaboration of public agencies with support from the Golden Gate National Parks Conservancy nonprofit group.

“Roy’s Redwoods was one of the first open space preserves in Marin County and it was a big community effort to get established,” said Rob LaPorte, co-project lead with the Conservancy. “I just hope the project, the way it is designed and the way we implement the build of it, continues to be community-based and is in the spirit of what the valley wants there.”
