Mount Tamalpais State Park Coastal Trails Rehabilitation Project

Mount Tamalpais State Park Coastal Trails Rehabilitation Project

The Department of Parks and Recreation proposes to make the improvements described herein to the Lone Tree and Coastal Fire Roads in the Mount Tamalpais State Park. - Convert one-half mile of existing road to trail by narrowing the road surface. Three-tenths of a mile of Coastal Fire Road and two-tenths of a mile of Lone Tree Road will be narrowed to trail. This portion of the project would involve the mechanical excavation of road embankment and landing fill, and stabilization of excavated materials on the inboard edge of the cutbench. A narrow portion of the road cutbench would be preserved to serve as the trail bed. - Construct new trail to replace the poorly aligned portions of the existing Coastal Fire Road that cannot be safely converted to trail, due to poor alignment, drainage problems, and/or erosion. Approximately 2.1 miles of trail would be realigned. - Decommission and re-contour 3.1 miles of poorly aligned sections of the fire roads (1.6 miles of Coastal Fire Road and 1.5 miles of Lone Tree Fire Road) to pre-disturbance topography by excavating embankment fill from the roads and stabilizing excavated material on the cutbench.' - Construct 0.2 mile of new Dipsea Trail where a current segment of this trail, that shares an alignment with the Lone Tree Fire Road, will be removed by the decommission of the Lone Tree Fire Road.
