Marin County Parks and Open Space Department

Road and Trail Projects

The Marin County Open Space District (MCOSD) road and trail projects are part of a science-based, public inclusive, comprehensive plan (RTMP) which addresses the complex challenges of MCOSD roads and trails. The plan was developed over the course of four years on the basis of extensive outreach and public input.   

The MCOSD road and trail projects are designed and implemented to reduce the environmental impact of the road and trail network and enhance visitor experience and safety. During the Road and Trail Management Plan (RTMP) planning process, the following five major habitat and trail improvement projects were prioritized for implementation during the 2016 season.

Fairway Trails Improvement Project and Adoption

Trail Decommission and Adoption in Camino Alto Preserve

This information is also available in a Fact Sheet

The existing network of unsanctioned social trails and abandoned roads near the end of Fairway Drive in Mill Valley is steep and redundant, with significant effects on natural resources. In order to adopt portions of these trails, the MCOSD road and trail crew will restore habitat and adopt portions of a network of trails. Work includes decommissiong and restoration of over 5,500 linear feet of trail and construction of approximately 1,700 linear feet of trail reroute.

The MCOSD has approved a portion of the Fairway Trails Project described in the Fact Sheet above. The MCOSD will proceed with the construction of trail improvements between the end of Valle Vista Avenue and the Del Casa Fire Road and the decommissioning of the social trials in the interior of the preserve. The remaining portions of the originally proposed project are on hold for now, while we evaluate use patterns on the existing trails. For more information about the project approval, please see the approved Negative Declaration.

The MCOSD has completed an Initial Study and Draft Mitigated Negative Declaration for this project. These documents are available for public review during a 30-day comment period.
