Eight miles of trail wind through the Del Mar Mesa Preserve, and depending on who you ask, none of them, some of them, or all of them belong to the city. That is not a riddle. It is the actual, unresolved situation that a volunteer nonprofit and a city planning board have been sorting through in public meetings all year, and it helps explain why trail maintenance remains an ongoing topic in the community.
If you walk the mesa often, you already know the texture: fire roads that dip into a scrub oak thicket at Tunnel 4, the loop out to the Bowtie Rim Trail, the kiosk near Rancho Toyon Place where riders and hikers negotiate the same narrow path. The Del Mar Mesa Preserve covers roughly 900 acres on the eastern edge of the community, connects into Los Peñasquitos Canyon, and is protected under the city's Multiple Species Habitat Plan because it holds vernal pools and plant and animal species found almost nowhere else in San Diego. What isn't obvious from the trail itself is who is actually responsible for keeping it walkable.
Friends of Del Mar Mesa's trail and habitat work
The organization doing most of the visible work is Friends of Del Mar Mesa, a nonprofit formed in 2013 by residents Preston Drake and Gary Levitt specifically to protect and maintain the habitat and recreational trails on the mesa. It is not a hobby group. Their active project list includes funding trail signage and resource markers inside the Preserve, designing a community identity sign at the Del Vino Court and Carmel Mountain Road entrance, and exploring bringing reclaimed water to the public right of way along Del Mar Mesa Road so the landscaping there can actually be maintained. They also administer a Del Mar Mesa and Carmel Valley Trail Maintenance and Enhancement Fund, seeded by a donation from Manchester Resorts, that pays for upkeep the city budget doesn't cover.
The community's own Garden Club, a nationally accredited group with more than 40 members that meets monthly and is open to residents across the 92130 zip code, also does adjacent work such as invasive plant removal.
What the planning board recorded about trail maintenance
The Del Mar Mesa Community Planning Board discussed the public trail along Del Vino Court and Carmel Mountain Road at its February 12, 2026 meeting. The board's minutes stated:
"It is clear that the city is responsible for care and maintenance of the public trail system along Del Vino Court/Carmel Mountain Rd but the City at present, has apparently opted out of that responsibility."
Board chair Paul Metcalf was tasked with following up directly with city contacts on the issue, and the item was still open as of that meeting.
Trail maintenance in Alta Del Mar
Alta Del Mar, one of the more recently built neighborhoods on the mesa, was the subject of its own trail-maintenance item on the board's March 12, 2026 draft agenda, separate from the general Del Vino Court discussion.
Other projects on the board's 2026 agenda
The Community Wildfire Protection Plan, a document running more than forty pages that governs brush management across the mesa's open space, was a funded project moving through 2026. As of the board's March meeting, the first two phases of brush removal were complete, with herbicide treatment underway and expected to finish in April. This is fuel management on land that borders houses, on a schedule the city is funding and tracking.
The board also spent time this spring on a Comprehensive Speed Management Plan tied to state legislation known as AB43, aimed at addressing traffic speed on mesa roads, and on a security subcommittee report noting that Flock license plate cameras are active at the Preserve and at the Three Canyons entrance. None of that is trail-specific, but it is a reminder that the same small board handling brush and speed limits is also the body fielding trail complaints, which may be part of why some issues take months to move.
What this actually means if you walk these trails
None of this should stop anyone from using the Preserve. The trail network is real, it is maintained more often than not, and the people doing that maintenance are, for the most part, your neighbors. Here are a few practical things to know:
- Trail maps and current conditions are more reliably found through Friends of Del Mar Mesa than through any city page, since the nonprofit is the group actually placing signage and tracking closures.
- The Del Mar Mesa Community Planning Board meets the second Thursday of every month, by Zoom or in person at the Ocean Air Recreation Center, and its agendas and minutes are posted on the city's planning department site before and after each meeting. If a specific stretch of trail looks neglected, that meeting is where it gets raised.
- Trail Fixer volunteer days do happen on the mesa, organized through the Friends group, and they offer residents a direct way to contribute labor to trail maintenance.
- If you are near Del Vino Court or Carmel Mountain Road specifically, the board minutes discuss responsibility for maintenance of this public trail. That does not make the trail unsafe. The board's meetings are a place to raise concerns about erosion or debris.
The mesa's appeal has always been that it feels less managed than the rest of Carmel Valley, more open space than subdivision. The 2026 planning board record documents ongoing discussion of trail upkeep, while a resident-founded nonprofit organizes trail work and the volunteer board considers related issues at meetings.
