If you live in Woodacre, San Geronimo, Forest Knolls, or Lagunitas, you have probably noticed that the Valley's edges are being redrawn faster than the middle. The Community Center still hums in the same building it has since 1969. The Deli still knows your order. But the trailheads, the old fire station lot, and the creek behind the school are all in motion this summer, and the decisions happening between June and September will shape the everyday geography of this place for a generation.
Here is what is actually going on, and where to point out-of-town visitors when they ask what changed.
A Fallen Branch, A Bigger Story At Roy's Redwoods
If you tried to take the easy loop last week and hit a closure sign, you are not imagining it. The Boardwalk Trail in Roy's Redwoods Preserve is temporarily closed due to a fallen tree branch, and Marin County Parks is working on repairs. The rest of the preserve is open, and the closure is worth mentioning only because it is a reminder of how young the new trail system still is.
Roy's Redwoods reopened last year after a $3.7 million restoration, and the site now covers 293 forested acres overlooking San Geronimo Valley, with old-growth forest, seasonal wildflower patches, and a bit of Star Wars history tucked in. Thousands of native plants went in, and 1,900 feet of wheelchair-accessible boardwalk is now in place. If you have not walked the Fairy Ring Trail since the work wrapped, the difference is obvious the second you step off the parking pad on Nicasio Valley Road. The old braided social trails that used to cut across the meadow are gone. The forest floor is coming back.
There is a real reason that matters beyond aesthetics. The project manager has said that visitors now stay on the trails and boardwalks, whereas in the past people crisscrossed the forest floor, waded through creeks, and trampled vegetation. If you have kids in Lagunitas School who go on field trips out here, that shift is what makes the trip repeatable without loving the grove to death.
The Comment Window Closes July 24
The next restoration project is already teed up, and if you want a say, the calendar is tight.
CEQA public comment for the proposed Buck Gulch Falls Creek Restoration and Trail Improvement Project runs from June 23 through July 24, 2026.
That is per the Marin County Parks project page. Buck Gulch drains a small but sensitive corner of the watershed, and any trail realignment there will affect how the northern loops connect. If you walk that side regularly, or if you are the kind of neighbor who reads the environmental documents cover to cover, this is the window.
The reason these creek projects are not academic here is a number most Valley residents already know but that visitors never grasp: San Geronimo Creek supports roughly 40% of the spawning activity in the entire Lagunitas Creek watershed. When people in Sacramento talk about protecting the last major coho run in the Bay Area, they are talking about the water running under the Sir Francis Drake bridge two blocks from your house.
What Happens To 33 Castle Rock
The bigger structural change is a mile east of the redwoods, on the ground everyone still calls "the golf course."
The former San Geronimo Golf Course, now known as San Geronimo Commons, is being transformed from an 18-hole course into a multi-benefit landscape that supports ecological restoration, community access, and public safety infrastructure. The course was built in the mid-1960s as part of a suburban vision that never materialized, struggled financially for decades, and was placed on the market in 2017 before the Trust for Public Land bought the 157-acre property in 2018 for approximately $8.8 million.
Then, in 2024, the property moved into public hands. The County agreed to purchase 5800 Sir Francis Drake Boulevard, totaling 157.3 acres, for $4.5 million plus roughly $45,000 in escrow costs and fees. May 21, 2024 marked the transition of San Geronimo Commons from the Trust for Public Land to public stewardship under the County of Marin.
The interesting piece for anyone who lives on Railroad, Redwood, or Castle Rock is what happens next to the fire station. Marin County Fire has been headquartered in Woodacre for the past century, but its outdated facilities and inaccessible location make it difficult to launch quick responses. The County Fire Department is planning to construct a station, training facility, and administrative offices on the existing clubhouse parcel, and the rest of the Commons will be shaped through continued ecological restoration and public engagement.
What that means in practice, once the move happens:
- The Castle Rock Avenue lot, which has held some form of fire company since around the founding of organized fire protection in the county, will be a former station in a wooded residential pocket.
- The Commons clubhouse parcel becomes a hub with modern apparatus bays and training space, positioned right on the main road.
- The property borders the Community Center, middle school, and elementary schools, and utilizing the existing pathways for pedestrian and bicycle traffic will remove children from the high-traffic, small-shoulder edge of Sir Francis Drake Boulevard.
For anyone who has ever tried to walk a kid from the Deli to the school on a Friday afternoon, that last piece is the sentence to reread.
The creek work is already underway on the property. Restoration crews are reestablishing floodplains, removing invasive species, and constructing side channels on San Geronimo and Larsen Creeks, both of which were historically manipulated by golf course pipes, culverts, and ponds.
The Small Places Still Doing The Work
While the big parcels are being reshuffled, the Valley's cultural life is still running out of the same handful of buildings it always has.
The San Geronimo Valley Community Center, founded in 1969, has served the four villages of the Valley plus Nicasio and surrounding West Marin communities, and remains a focal point for programs in the arts, youth programming, and human services. The summer calendar is thick: Summer Bridge Camp 2026, Summer Day Camp 2026, and youth programs including the new Dungeons & Dragons Youth Game Night, plus the LOFT and open gym are all running out of 6350 Sir Francis Drake.
The music side of the Center's programming has been leaning local. Earlier this season the room hosted a bass-led project by Owen Clapp, a Valley-raised musician; Clapp has played with a range of artists including Grammy winners Jonah Levine, Ruslan Sirota, Mads Tolling, Evan Price, and Bill Cunliffe, joined by Jonathan Pinson on drums and Gregory Uhlmann on guitar. Keep an eye on the Center's calendar and on shows over at Giaco's Valley Roadhouse, which continues to partner with the Center on off-site programming.
For food, the map has not changed much, and that is its own kind of good news. The Woodacre market continues to draw locals for sandwiches and provisions, and the Lagunitas Store remains what it has been for years: the last stop for nourishment before the forested vale of Samuel P. Taylor. If you are heading out toward Point Reyes with weekend guests, that is the picnic stop, and it is worth telling them the building has functioned as a store on that site for more than a century.
Why This Summer Matters More Than Most
Put the pieces on one map. A restored old-growth preserve with a brand-new accessible boardwalk. A creek restoration project one signature away from its next phase, with a comment window closing July 24. A 157-acre former golf course transitioning from private ownership to a public commons with a fire headquarters, a trail network, and a restored salmon-bearing creek. A century-old fire station about to become a former fire station in a residential neighborhood. Two schools and a community center about to be linked to all of it by pathways that keep kids off the shoulder of Sir Francis Drake.
None of these are speculative. Each has a document, a date, or an escrow behind it. The choices about what the Valley feels like at ground level in 2030, which trails connect to which, where the sirens come from, where the kids walk after school, are being made in public meetings this year.
If you are thinking about how any of this affects your own property, whether that means a long-held family home near the old fire station, a hillside parcel bordering the new Commons trails, or an inherited house you have not decided what to do with yet, that is a conversation worth having early rather than late. Livein415 is Marin-raised, works these back roads every week, and is glad to sit down for a 15-minute consultation before the next round of Valley decisions gets made without you.
