The Marin County Open Space District (MCOSD) has recently approved the Region 1 proposed conditional designation maps for six southeastern Marin preserves. This decision comes after a thorough evaluation of public comments and represents a significant step in managing the region’s natural resources and recreational opportunities.
Approved Maps
Region 1 Designation Map
The Region 1 Designation Map outlines the designated roads and trails for the following preserves:
- Alto Bowl
- Baltimore Canyon
- Blithedale Summit
- Camino Alto
- Horse Hill
- King Mountain
This comprehensive map provides a clear overview of the approved routes within these preserves, ensuring that visitors can navigate the area with confidence while minimizing impact on sensitive ecosystems.
Region 1 Use Map
Complementing the Designation Map, the Region 1 Use Map specifies the designated uses for various user groups on the roads and trails within Region 1 preserves. This map is essential for:
- Hikers
- Cyclists
- Equestrians
By clearly defining allowed activities on each trail, the Use Map helps prevent conflicts between different user groups and protects the natural environment from overuse.
Location and Context
Region 1 is situated in the southeastern portion of Marin County, encompassing six open space preserves that total approximately 1,197 acres. The region includes:
- Alto Bowl
- Baltimore Canyon (193 acres)
- Blithedale Summit (640 acres)
- Camino Alto (170 acres)
- Horse Hill
- King Mountain
With approximately 34 miles of roads and trails, Region 1 offers extensive recreational opportunities for local residents and visitors alike.
Surrounding Areas
The region is strategically located near several other significant natural and urban areas:
- Mount Tamalpais State Park (west)
- Golden Gate National Recreation Area (west)
- Homestead Valley public lands and private residences (south)
- Piper Park, U.S. Highway 101, and residential areas (east)
- Hal Brown Park, College of Marin, and residences (north)
Adjacent Land Use
Within a quarter-mile of the MCOSD roads and trails in Region 1, the adjacent land use is diverse:
- Residential use: 1,491 acres (66.5%)
- Other open space: 412 acres (18.3%)
- Public or quasi-public use: 286 acres (12.7%)
- Commercial/mixed uses: 53 acres (2.3%)
This mix of land uses highlights the importance of careful management to balance conservation efforts with recreational access and urban development.
Community Engagement
The MCOSD recognizes the importance of public input in the decision-making process. As part of their commitment to community engagement, a Region 1 Designation public workshop was held on March 22, 2015. This workshop provided an opportunity for local residents and stakeholders to:
- Learn about the proposed designations
- Ask questions and seek clarification
- Provide feedback and suggestions
- Contribute to the final decision-making process
The workshop presentation, available as a PDF document, offers detailed information on the designation process and proposed changes.
The approval of the Region 1 proposed conditional designation maps represents a significant milestone in the management of Marin County’s open spaces. By carefully balancing the needs of various user groups with environmental conservation, the MCOSD has taken an important step towards ensuring the long-term sustainability of these valuable natural resources.
The designated roads and trails, along with clearly defined usage guidelines, will help preserve the ecological integrity of the preserves while providing ample opportunities for outdoor recreation. As the community continues to engage with these open spaces, ongoing monitoring and adjustment of the management strategies will be crucial to maintain this delicate balance.
Visitors to Region 1 preserves are encouraged to familiarize themselves with the new designation and use maps to ensure they are using the trails responsibly and in accordance with the approved guidelines. By working together, the community can help protect and enjoy these beautiful open spaces for generations to come.
