Coastside on Bikes: “A Quarry Park Public Engagement Session was held on July 8th, 2026, regarding the development of single-track trail standards. Avid Trails has been tasked with assessing the park and creating a comprehensive mountain bike trail standards package.

This was the first of three community engagement meetings focused on establishing single track standards for Quarry Park. The meeting was attended by representatives from San Mateo County Parks, including several rangers, and Avid Trails, a company hired to draft the single track standards document and conduct an inventory of the park.

The primary focus of the meeting was on reviewing the team’s findings regarding the current state of the park and gathering feedback from user groups. Several pictures from the breakout sessions captured the individuals’ suggestions, which ranged from verbal to written.

This was specifically a meeting about mountain bike trails getting feedback from Mountain Bikers. These existing trails were built by mountain Bikers 4 mountain Bikers. All the trails that they are referring to would be designated as mountain bike only, not hiking or equestrian.

There will be two more meetings to include hikers, equestrians and the general public.

As the team refines their document, two more meetings are scheduled to further refine the standards.”


Project Goals: Avid Trails is working toward several key objectives:

  • Developing trail design guidelines focused on user experience and safety, including signage, wayfinding, and a trail rating system.
  • Creating environmental standards for sustainable construction, erosion control, and habitat protection.
  • Establishing maintenance standards for vegetation management and long-term sustainability.

Site Assessment: The assessment of Quarry Park identified 17 trails totaling 4.1 miles. Key findings include:

  • The network is robust and generally well-maintained, though trails trend toward higher difficulty levels.
  • Inconsistent difficulty and hazardous intersections with fireroads were identified as areas for improvement.
  • Specific trail issues, such as erosion on Black Mamba and drainage exits on Moloch and EG Bus, were documented.

Public Engagement: An online survey conducted in April 2026 received 679 responses. Respondents highlighted a desire for:

  • Expanded trail systems, better signage and maps, and improved maintenance.
  • Better safety and shared-use management to address conflicts, such as off-leash dogs and mountain bike interactions.
  • Concerns regarding trail difficulty, the need for clear signage to prevent riders from being overwhelmed, and requests to avoid “sanitizing” existing trails.

Following the presentation, participants were invited to a breakout session to provide direct feedback on the trail system via poster boards. The project will proceed with the development of draft standards.
