Trail Advocacy & Projects
The San Diego Mountain Biking Association staff and volunteers work every day to improve trail access for mountain biking in San Diego County. These efforts include keeping in regular contact with federal, state and local land managers, communicating the need for more and better trails with elected officials, locating funding and opportunities for partnerships, understanding where the opportunities and constraints exist, and prioritizing our work in order to use our time effectively.
Working on trails and advocacy generally takes two forms - short term projects and long term efforts.
Short term projects can include trimming/brushing, tread work projects to control erosion, and even bridge replacement. Many factors have to be taken into consideration such as weather, soil conditions, funding, city/county/agency permission and staff availability, and whether the appropriate environmental studies are completed if necessary.
Long term efforts include all of the work that happens before the shovels can even hit the ground. This work is all about meetings, emails, phone calls, being involved in public planning processes and public comment periods, keeping an eye on jurisdictional agendas and land use decisions which might affect current or future trail access, engaging other stakeholder groups, and so much more. Master Trails Plans, Public Access Plans and general park planning are all part of the mix. These plans can occur in the same open spaces or parks where short term efforts continue each season. Developing and getting these plans approved and implemented can take years, if not decades. This the long game that is necessary to ensure that we have trails now and in the future.
There are many opportunities in San Diego for improved recreational trail access but there are also significant issues and challenges. The complexities of land ownership, mitigation, and conservation land and habitat protection requirements along with future development mixed in with federally listed endangered species, cultural resources and water management are a few of the constraints placed on trail development or improvement. There needs to be a balance between the conservation of our open spaces combined with responsible management and reasonable public access.
Here are some of our ongoing trail projects, advocacy efforts and programs.
