Drive Sierra Highway through Acton on any given morning and you'll pass the same string of buildings you've passed for years: the Jack in the Box, the 76 station, Acton Auto Parts, the empty lot north of the freeway exit that's been empty for so long most people stopped registering it as a construction site at all. It's just there, a gap in the frontage road, the kind of vacant parcel that blends into the drive.
That lot has a name attached to it now, and if you've sat through a Town Council meeting in the past year, you already know it: Primo Burger. What you might not know is that the rule Acton wrote specifically to stop projects like this one may not actually stop this one.
The Feed Store That Became a Burger Joint
The story starts in 2016, and it starts with a bait and switch that longtime residents still bring up. The property got a zone change through the county's Development Program, a fast-track process that trades a longer public review for a promise: build exactly what's on the site plan you submitted, nothing more. What residents saw on that plan was a new home for Country Club Feed, a local feed store relocating down the highway.
The drive-thru burger restaurant showed up after the zone change was already approved. Ruthie Brock of Acton Takes Action has said plainly that the fast-food element was added later, once the faster approval was already locked in. Residents didn't organize against a restaurant. They organized against a drive-thru that turned a neighborhood-serving site into something built for freeway traffic passing through.
That organizing had a name: Save Our Rural Town, or SORT. The group sued, arguing the traffic and environmental review behind the original approval didn't account for what a drive-thru actually does to that stretch of highway. In 2021, a Los Angeles Superior Court judge agreed, vacating the project's entitlements and ordering the county back to the drawing board on traffic.
The Rule Built From This Exact Fight
Somewhere in the years after that ruling, the Acton Community Standards District, the zoning code that governs what can and can't be built in town, got amended. New drive-thrus are now prohibited under the CSD. Brock has said the change was a direct response to the Primo Burger controversy. It's the kind of rule a community writes when it decides one fight was enough and wants to make sure the next developer doesn't get the chance to have the same one.
"The issue isn't the restaurant, it's the drive-thru," Brock has said of the project. "It changed the nature of the project into something that serves freeway traffic rather than our rural community."
If you stopped reading there, you'd assume the story ends cleanly: Acton banned drive-thrus, so the drive-thru dies with the ban. That's not quite what's happening.
Why the Ban Might Not Reach the Project It Was Written For
Here's the part that surprises people who haven't followed the procedural details closely. The 2021 court order didn't send Primo Burger back through zoning as a brand-new application subject to the current CSD. It vacated the entitlements and required a new environmental and traffic study, an Initial Study and Mitigated Negative Declaration that the LA County Department of Regional Planning released for public comment through July 12, 2025. That study concluded the project would cause no significant environmental impacts.
What it didn't do is force the drive-thru to justify itself under a rule that didn't exist when the project was first approved. At the Town Council's June 7, 2025 meeting, residents argued the drive-thru shouldn't be treated as grandfathered in, since it doesn't comply with the current CSD. The fact that they had to make that argument at all tells you where the default sits: the county's working assumption is that a project approved in 2016, even one whose entitlements were later vacated for procedural reasons, isn't automatically subject to a zoning rule written after the fact. Residents have to actively push for the opposite outcome. Nothing guarantees they'll get it.
As of the most recent reporting, no public hearing date has been set for the project.
What's Already There, and What's Being Added Next to It
Part of what makes this feel urgent to residents isn't abstract zoning theory. It's the math of what's already sitting on that half-mile of highway. A 2016 public comment on the project put it simply: Acton already had three hamburger drive-thru restaurants along Sierra Highway before Primo Burger was even in the conversation.
The current version of the project, as described in county filings, includes:
- A 3,300-square-foot Primo Burger restaurant with a drive-thru
- A 6,000-square-foot retail building, including the relocated feed store and two additional retail units
- A 1,600-square-foot storage building
- A proposed land division on the same parcel
The site sits just north of the 14 Freeway exit, between the existing Jack in the Box and Acton Auto Parts. And it isn't the only project moving through the pipeline at that intersection. A separate, still-early-stage proposal would put a 24-hour gas station a few hundred feet away, next to the existing 76 station, with a convenience store, restaurant space, eight fuel pumps, and future EV charging. Town Council Recording Secretary Kelly Teno has described the combined effect as overconcentration, calling it an attempt to carve out a commuter hub at the freeway exit rather than a use that serves the town behind it.
Council Correspondence Secretary Jacqueline Ayer has raised the same concern from a different angle: two large-scale commercial projects being considered side by side, on a highway that residents keep describing as a rural main street, not a truck stop corridor.
The Weekend Doesn't Wait on a Hearing Date
None of this changes what Saturday actually looks like in Acton, and that's worth sitting with for a second. A few miles off Sierra Highway, DeBellis Ranch is still open on Aliso Canyon Road, the same u-pick flower farm where a family that moved out for more space nine years ago ended up running a working farm instead. The rows get cut by hand, the cats patrol for rabbits, and the farm stand runs on whatever hours the season allows.
Closer to the highway, the 49er Saloon has been open since 1889, back when Acton was still a mining town considered, briefly, as a candidate for the state capital. The comfort food and the hitching rail out front haven't changed regardless of what's happening at the county planning level a few miles away.
That contrast matters. The zoning fight is real and it will shape what the highway looks like for the next decade. But it isn't the only thing defining life here, and it's worth remembering both are true at once.
What to Watch For
If you want to follow this without waiting for the next news cycle, the Acton Town Council posts hearing notices and hot topics directly on its site, and it's the fastest way to know when a hearing date finally gets scheduled. The council also has six seats up for election on November 3, 2026, a reminder that the people arguing over drive-thru grandfather clauses are neighbors who ran for a volunteer position, not appointed bureaucrats.
Whatever the county decides about the drive-thru, it will say something about how much weight a rural community's own zoning rules carry against a project that predates them. That's a bigger question than one burger restaurant, and it's one Acton residents are still actively fighting to answer.
