In March, a Malibu city councilmember got a straight answer she did not like. Councilmember Haylynn Conrad had been pressing Caltrans for months on when the Zuma Creek underpass at Busch Drive would reopen. The answer she got back was not a timeline. It was a shrug dressed up as policy: the crossing might not reopen at all.
That exchange, reported by RadioMalibu.net in late March, is the piece of information that changes how you should read everything else happening at Zuma this year. Not as a maintenance delay. As a decision that has already been made by inertia, and that the neighborhood is only now catching up to.
What The Underpass Actually Connects
The Zuma Creek underpass sits at Busch Drive, running beneath Pacific Coast Highway to link Westward Beach Road with the main Zuma Beach parking lot. For anyone who lives on the Point Dume side or in Malibu West, it has historically been the short way in: park off Westward, walk the underpass, land near Tower 6 without ever merging onto PCH traffic. It is not scenic. It is not a landmark. It is a piece of civil infrastructure that a lot of daily routines were quietly built around.
It has also been closed, on and off, since early 2023, after severe winter storms left it packed with sediment and debris. That timeline matters. This is not a problem that showed up this year. It is a problem that showed up three years ago and has never actually gone away, only shifted between "closed" and "closed with an active cleanup effort."
The Cleanup That Undid Itself Within Days
This year's attempt at a fix is the clearest evidence that the old playbook no longer works. County crews got emergency authorization from the Los Angeles Regional Water Quality Control Board and began clearing sediment and debris during the weeks of April 13 and April 20, 2026, with a biological monitor on site and sign-off from Caltrans, the California Department of Fish and Wildlife, and the U.S. Army Corps of Engineers. That is four agencies coordinating to remove dirt from a tunnel.
Within days, the underpass filled back up with roughly 10 inches of standing water, driven by elevated groundwater and surface flow from Zuma Creek itself. The dirt was never really the problem. The water table underneath the crossing is.
On May 7, 2026, the Regional Board told the County to stop trying to dewater the site and leave conditions as they were until groundwater levels dropped on their own. A month later, on June 11, 2026, County and City of Malibu staff sat down with the Regional Board again to see if there was any permitting path back to active dewatering. The Board said it would consider it. As of the City of Malibu's own advisory posted July 2, ahead of the Independence Day weekend, the underpass was still closed, PCH traffic backups were expected at the Zuma main entrance, and the access road between Westward and Zuma was flagged as subject to further closures from high tides and surf.
Read that sequence in order and the pattern is not a repair job in progress. It is a site where the fix keeps failing on contact with the actual hydrology, and where the agency with jurisdiction has told the County to stop trying for now.
The Fish That Changed The Rules
There is a second reason this year reads differently from prior closures, and it has nothing to do with rainfall. The flooded underpass has become habitat for the tidewater goby, a federally protected species. In past years, when the crossing flooded, the standard workaround was a temporary bridge for pedestrians and cyclists. That option is effectively off the table now, because building a temporary structure over occupied habitat for an endangered fish triggers a different, slower category of federal review.
This is why the current closure cannot be treated like the last one. The old failure mode was seasonal: heavy rain, debris, a cleanup crew, reopening by summer. The new failure mode is regulatory and ecological, and it does not resolve on a weather cycle. A 2015 traffic study, cited by RadioMalibu.net in its reporting on the Caltrans exchange, had already recommended abandoning the underpass model entirely and routing Zuma and Westward Beach access through a signalized intersection at PCH and Busch Drive instead. That recommendation sat unused for nearly a decade. It only became relevant once the crossing flooded and stayed flooded.
How The Corridor Has Actually Rerouted
None of this has closed Zuma Beach. The main entrance remains open from both directions of PCH, and Westward Beach Road still gets you to the sand, just without the underpass shortcut. What has changed is the texture of a normal week for anyone on the west side of that stretch.
Weekday mornings that used to route straight through Busch Drive now run through the PCH signal instead, with the City's own advisories warning of stopped traffic in the left lane during peak arrival windows. Race mornings are a specific case worth knowing if you live nearby. The event now organized as the Zuma Foundation's race series, which took over the permit from the original Malibu Triathlon organizers in September 2023, has historically run its course straight through the Busch Drive underpass. With that crossing gone, anyone timing a weekend around race traffic is now working from a rerouted course rather than the old one.
The practical shift for a lot of households has been less about detours and more about default plans. If the fifteen-minute beach walk now involves a PCH crossing and a parking search, the fifteen-minute alternative, a coffee or an early dinner at Trancas Country Market a few minutes up the highway, starts absorbing time that used to go to the sand. That is not a lifestyle upgrade or a downgrade. It is what a neighborhood does when one piece of its daily infrastructure goes offline for what is starting to look like the long term rather than a season.
Why Fall Doesn't Reset The Clock
There is a temptation to assume this resolves once the wet season fully passes and groundwater drops on its own, the way the Regional Board's May directive implied it might. That assumption runs into a scheduling problem. Zuma is one of the more reliable spots along this stretch of coast to watch the gray whale migration once it gets underway in the winter months, which means visitor volume at the beach tends to climb again just as Southern California's next wet season begins building groundwater back up under Busch Drive.
In other words, the narrow window when the underpass might plausibly dry out on its own, and when a resumed permitting conversation might actually produce cleared water rather than another directive to leave it alone, sits right before the season that refills it. That is not a reason to expect bad news. It is a reason not to expect a reopening announcement anytime soon, and to plan the winter beach routine the way the summer one already got planned: around the PCH entrance, not through Busch Drive.
The Realistic Read
Nothing in the record suggests anyone is sitting on a fix and simply declining to install it. The agencies involved are working through a genuinely complicated site, one where habitat protection and hydrology have made a straightforward maintenance job into a multi-agency negotiation. What the record does suggest, plainly, is that the people closest to the jurisdiction, a Caltrans official speaking directly to a sitting councilmember, do not expect a reopening on any near-term horizon, and the underlying traffic study behind that skepticism dates back over a decade.
For anyone living along this part of the coast, the useful move is the same one the neighborhood has already made without waiting for an official announcement: treat the Busch Drive crossing as gone rather than paused, and build the routine around PCH and Westward Beach Road accordingly. If the underpass does reopen, that will be the pleasant surprise. Planning as if it will not costs nothing and matches what the people actually running the permitting process seem to believe.
