Federal, state and county agencies last week announced a collaborative effort to remedy parking problems at Muir Woods National Monument, where traffic is compromising both public safety and enjoyment. Congestion at the monument and in nearby Mount Tamalpais State Park, combined with gaps in trail and pedestrian systems, is resulting in visitors routinely parking along an undeveloped shoulder of Muir Woods Road and then walking on the narrow road to the entrance. Interested parties are invited to weigh in on two plans: the first focuses on operational improvements, including reservation parking and expanded shuttle service, the second on site improvements. A public scoping meeting during which representatives from the National Park Service, California State Parks and the Marin County Board of Supervisors will discuss the projects and hear input will take place Wednesday, Sept. 18 from 6:30 to 8:30 p.m. in the Multi-purpose Room at Tam Valley Elementary School, in Mill Valley. Written comments will be accepted through October 4 and can be submitted either in person at the meeting; by mail to Golden Gate National Recreation Area, Attn: Muir Woods Transportation Projects, Building 201, Fort Mason, San Francisco, CA 94123; or online at http://parkplanning.nps.gov.
