2017 Road and Trail Projects

The Marin County Open Space District (MCOSD) road and trail projects are part of a science-based, public inclusive, comprehensive Road and Trail Management 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. For information about 2016 projects, visit the Road & Trail Projects Archive.

Hunt Camp Trail Update

POSTED ON: JUNE 8, 2017

The Marin County Open Space District (MCOSD) has accepted the proposal to improve the Hunt Camp Trail and incorporate it into the MCOSD trail system as a hiker/biker trail and is moving forward with the project. The proposal includes two reroutes on Upper Hunt Camp and the installation of wet crossings and drainage improvements along the trail. The improvements would ensure the trail is properly drained and would minimize environmental impacts, while maximizing user safety. The proposal also includes a new connecter trail for hikers and cyclists, which would be constructed from the Lower Hunt Camp Trail to Manzanita Fire Road and a small portion of the existing Hunt Camp Trail, connecting to Juniper Avenue, would be designated as hiking only.

The project description was circulated for a 30-day administrative comment period from April 13 to May 15, 2017. A total of 134 public comments were received, with the majority favoring the proposed change. The project will now be evaluated pursuant to the California Environmental Quality Act (CEQA). After completion of CEQA, MCOSD will consider approval of the project. Additional project tasks include conducting resource surveys and completing environmental permitting. The MCOSD anticipates work will begin in fall 2017.

Bob Middagh and Gasline Trails
California Environmental Quality Act Documentation

POSTED ON: MAY 12, 2017

The Marin County Open Space District (MCOSD) has approved the proposed improvements to the Bob Middagh and Gasline Trails in the Alto Bowl Open Space Preserve. These projects are moving forward, including realigning both trails to reduce their running slopes, improving erosion control measures, replacing failed culverts, improving accessibility, and reducing safety hazards. As part of this project, the MCOSD is designating Bob Middagh Trail for hiking, biking, and equestrian multiuse.

The MCOSD has completed a CEQA consistency analysis to determine if the project requires a negative determination or environmental impact report (EIR). The consistency analysis concluded that the projects are consistent with the RTMP EIR, because they do not result in new or more significant impacts from project changes, changed circumstances, or new information. Based on this document, the MCOSD determined that it is not necessary to prepare a new EIR or negative determination. The consistency analysis, notice of determination and supporting documents are listed below. These documents are also available for public review at the Marin County Parks, Administrative Office, Marin County Civic Center, 3501 Civic Center Drive, Suite 260, San Rafael.

Irving Fire Road Sustainability Project

POSTED ON: MAY 11, 2017

On May 15, 2017, Marin County Parks will begin work on Irving Fire Road in Terra Linda/Sleepy Hollow Open Space Preserve. This project will reduce sedimentation into the watershed and maintain safe emergency access. Construction is expected to be completed by the end of June. For safety, please observe posted trail caution and closure signs while work is taking place. This project is funded by Measure A.

Horse Hill Trail Realignment and
Restoration Project

POSTED ON: MAY 11, 2017

On May 15, 2017, Marin County Parks will begin work on two trails in Horse Hill Preserve. Horse Hill Trail is being extended 2,000 feet. Gasline Trail will be decommissioned due to steep terrain and erosion. The project will improve trail safety and restore grasslands. Construction is expected to be completed by the end of June. For safety, please observe posted trail caution and closure signs while work is taking place. This project is funded by Measure A.

Trail Decommission and Adoption:
Gary Giacomini

POSTED ON: APRIL 13, 2017

The MCOSD road and trail crew will restore habitat and adopt portions of a network of previously unsanctioned trails in the Gary Giacomini Preserve, including decommission and restoration, drainage improvements, visitor safety improvements, and adopting the historic Hunt Camp Trail as a hiking and biking accessible trail.
