The Marin County Board of Supervisors will hear an update on the parking reservation system and traffic control measures at the Muir Woods National Monument at a meeting on May 4.

Marin County entered into a memorandum of understanding with the National Park Service in 2015 to help with the long-term sustainability of the Muir Woods National Monument, which is visited by over a million people each year.

Under the agreement, updates about Muir Woods are provided through public meetings twice a year.

Three years ago, the National Park Service started a parking reservation system to help with crowd control, public access, park safety and preservation.

The park is accessed at Muir Woods Road and Frank Valley Road and parking restrictions such as traffic barriers, wooden posts and no parking zones have been implemented in those areas. The park service has also enhanced the Muir Woods shuttle program to help with access to the park.

Based on public feedback and park usage data, the reservation system has been effective at reducing congestion in and around the park and it has improved the visitor experience while in the park.

Additionally, it has reduced adverse impacts to the Muir Woods and Redwood Creek watersheds that were identified prior to the implementation of the parking restrictions and reservation system.

Still, there is work to be done.

The park service and the county are committed to a phased elimination of parking outside of the monument’s boundaries. The May 4 progress update will provide a detailed rundown of what has been accomplished since the previous update last October and what the public can expect moving forward.
