Who We Are
Launched in October 2023, we strive to serve as a long-term, trusted partner of California State Parks and related stakeholders at Mount Diablo State Park, helping bridge gaps in conservation and recreation goals and staffing and resource constraints.

Our Mission
Build a sustainable Shared Stewardship model with California State Parks to achieve the three main trail-related goals of the 2016 Road and Trail Management Plan (RTMP) for Mount Diablo State Park:

  1. Operate a regular trail maintenance and repair program, adhering to the standards and techniques prescribed in the California Department of Parks and Recreation (DPR) Trails Handbook.

  2. Improve relative trail access ratios across the main user groups by expanding circulation, connector and loop options for cyclists through the evaluation and implementation of change-in-use (CIU) policy recommendations.

  3. Evaluate non-system trails for removal to limit resource impacts.

To support the Shared Stewardship model, we recruit and educate volunteers to participate in trail maintenance and repair projects called Dig Days, which are fast-becoming an integral component to achieving the 2016 RTMP’s trail-related goals.

California State Parks’ managers and staff plan, review, approve, and manage the Dig Day projects and related operations. California State Parks also provides essential tools and equipment at Dig Days.

The Shared Stewardship model enables volunteers to work together and learn about each other’s interests and goals while supporting both the 2016 RTMP-based policy recommendations and the broader mission of California State Parks:

Protect the environment and biodiversity while providing high-quality outdoor recreational opportunities for park visitors.

Shared Stewardship

Help Us Build on the Early Momentum


Thanks to the dedication and efforts of our amazing volunteers, the Shared Stewardship model already is facilitating the implementation of the 2016 RTMP for Mount Diablo State Park.

A regular, at-scale trail maintenance and repair program now is active, and it is volunteer-powered. Since October 2023, 700+ volunteers have logged nearly 5,000 hours at Dig Days servicing 10 miles of trails, making them better and safer for park visitors and the environment.

  • The long-term goal is to service all 52.5 miles of singletrack trails at Mount Diablo State Park on a 7-to-8-year cycle.

  • All trail maintenance and repair work at Dig Days adhere to the standards of the California DPR Trails Handbook.

The long-term achievement of the 2016 RTMP’s three main trail goals stands to establish Mount Diablo State Park as a beacon for balancing conservation and recreation interests.
