The National Park Service’s proposed online parking reservation system for the Muir Woods National Monument is open for public comment until Nov. 22. The new system would compel individual visitors to reserve one of 232 available parking spots for their vehicles through a third-party operator, and commercial shuttles to reserve one of 16 spots through a separate system. The park is also proposing to expand shuttle service through Marin Transit to the monument. Parking on roads leading to the park would also be substantially reduced to 30 permitted spots, a move intended to eliminate the 400 or so cars the cram crumbling roadsides on peak-visitation summer days. Ultimately, the park is hoping to cut average daily summer visitation levels from the current 5,000 to 6,500 visitors on peak days down to around 4,200 visitors. Aside from the reservation system, the park outlines in the assessment its plans to increase the Muir Woods entry fee from $7 to $10 per visitor and to improve several facilities, including parking lots, pedestrian trails, restrooms and vehicle loading and unloading areas through 2021. Additionally, Marin County will be charged with repairing roads between the monument’s entrance and Highway 1 and rehabilitating the bridge over Redwood Creek by 2018. The assessment does not examine any potential impacts to water quality, threatened or endangered species, wildlife habitat, vegetation or air quality. Once the environmental assessment is finalized, the park will sign a memorandum of understanding with Marin County, said Howard Levitt, the Golden Gate National Recreation Area’s spokesman, in an email. That memorandum, aside from outlining the reservation system, gives the park enforcement authority along Muir Woods Road. Critics of the park’s plan see shortfalls in protections for endangered coho salmon populations in Redwood Creek and worry about increasing shuttle service on narrow roadways.
