The Brief

The most important stories for you to know today
  • Departments are updating their approach
    A firefighter with light skin tone stands next to his Cal Fire service vehicle and looks at the camera.
    Cal Fire Division Chief Jon Heggie, shown at San Diego County Fire Station 44 in Pine Valley, served as a fire behavior specialist for one of California's worst wildfires, the 2020 CZU Lightning Complex.

    Topline:

    As nights warm and droughts intensify, past models predicting fire behavior have become unreliable. So California is working with analysts and tapping into new technology to figure out how to attack wildfires. Gleaned from military satellites, drones and infrared mapping, the information is spat out in real time and triaged by a fire behavior analyst.

    Why it matters: Cal Fire officials warn that this year’s conditions are similar to the summer and fall of 2017 — when a rainy winter was followed by one of the state’s most destructive fire seasons, killing 47 people and destroying almost 11,000 structures.

    Read more ... for a big breakdown of what the data has been showing, and how drones and AI have become important tools.

    Cal Fire Battalion Chief Jon Heggie wasn’t expecting much to worry about when a late summer fire erupted north of Santa Cruz, home to California’s moist and cool “asbestos forests.” This place doesn’t burn, he thought, with just three notable fires there in 70 years.

    Heggie’s job was to predict for the crews where the wildfire might go and when, working through calculations based on topography, weather and fuels — the “immutable” basics. For fire behavior analysts like Heggie, predictable and familiar are manageable, while weird and unexpected are synonyms for danger.

    But that 2020 fire was anything but predictable.

    Around 3 a.m. on Aug. 16, ominous thunder cells formed over the region. Tens of thousands of lightning strikes rained down, creating a convulsion of fire that became the CZU Lightning Complex.

    By noon there were nearly two dozen fires burning, and not nearly enough people to handle them. Flames were roaring throughout the Coast Range in deep-shaded forests and waist-high ferns in sight of the Pacific Ocean. No one had ever seen anything like it. The blaze defied predictions and ran unchecked for a month. The fire spread to San Mateo County, burned through 86,000 acres, destroyed almost 1,500 structures and killed a fleeing resident.

    “It was astonishing to see that behavior and consumption of heavy fuels,” Heggie said. “Seeing the devastation was mind-boggling. Things were burning outside the norm. I hadn’t seen anything burn that intensely in my 30 years.”

    Almost as troubling was what this fire didn’t do — it didn’t back off at night.

    “We would have burning periods increase in the afternoon, and we saw continuous high-intensity burns in the night,” Heggie said. “That’s when we are supposed to make up ground. That didn’t happen.”

    That 2020 summer of fires, the worst in California history, recalibrated what veteran firefighters understand about fire behavior: Nothing is as it was.

    Intensified by climate change, especially warmer nights and longer droughts, California’s fires often morph into megafires, and even gigafires covering more than a million acres. U.S. wildfires have been four times larger and three times more frequent since 2000, according to University of Colorado researchers. And other scientists recently predicted that up to 52% more California forest acreage will burn in summertime over the next two decades because of the changing climate.

    As California now heads into its peak time for wildfires, even with last year’s quiet season and the end of its three-year drought, the specter of megafires hasn’t receded. Last winter’s record winter rains, rather than tamping down fire threats, have promoted lush growth, which provides more fuel for summer fires.

    Cal Fire officials warn that this year’s conditions are similar to the summer and fall of 2017 — when a rainy winter was followed by one of the state’s most destructive fire seasons, killing 47 people and destroying almost 11,000 structures.

    It’s not just the size and power of modern wildfires, but their capricious behavior that has confounded fire veterans — the feints and shifts that bedevil efforts to predict what a fire might do and then devise strategies to stop it. It’s a dangerous calculation: In the literal heat of a fire, choices are consequential. People’s lives and livelihoods are at stake.

    Cal Fire crews now often find themselves outflanked. Responding to larger and more erratic and intense fires requires more personnel and equipment. And staging crews and engines where flames are expected to go has been thrown off-kilter.

    “We live in this new reality,” Gov. Gavin Newsom said at a recent Cal Fire event, “where we can’t necessarily attach ourselves to some of the more predictive models of the past because of a world that is getting a lot hotter, a lot drier and a lot more uncertain because of climate change.”

    CalFire has responded by tapping into all the new technology — such as drones, military satellites, infrared images and AI-assisted maps — that can be brought to bear during a fire. Commanders now must consider a broader range of possibilities so they can pivot when the firefront shifts in an unexpected way. The agency also has beefed up its ability to fight nighttime fires with a new fleet of Fire Hawk helicopters equipped to fly in darkness.

    We live in this new reality ... We’re enlisting cutting-edge technology in our efforts to fight wildfires, exploring how innovations like artificial intelligence can help us identify threats quicker and deploy resources smarter.
    — Gov. Gavin Newsom

    The state has thrown every possible data point at the problem with its year-old Wildfire Threat and Intelligence Integration Center, which pulls information from dozens of federal, state and private sources to create a minute-by-minute picture of conditions conducive to sparking or spreading fires.

    “We’re enlisting cutting-edge technology in our efforts to fight wildfires,” Newsom said, “exploring how innovations like artificial intelligence can help us identify threats quicker and deploy resources smarter.”

    An unforeseen assault on a coastal town

    The 2017 Thomas Fire stands as an example of what happens when a massive fire, ignited after a rainy winter, veers and shifts in unexpected ways.

    The blaze in coastal Ventura and Santa Barbara counties struck in December, when fire season normally has quieted down. Fire veterans knew fall and winter fires were tamed by a blanket of moist air and fog.

    But that didn’t happen.

    “We were on day five or six, and the incident commander comes to me and asks, ‘Are we going to have to evacuate Carpinteria tonight?’,” said Cal Fire Assistant Chief Tim Chavez, who was the fire behavior analyst for the Thomas Fire. “I looked at the maps and we both came to the conclusion that Carpinteria would be fine, don’t worry. Sure enough, that night it burned into Carpinteria and they had to evacuate the town.”

    Based on fire and weather data and informed hunches, no one expected the fire to continue advancing overnight. And, as the winds calmed, no one predicted the blaze would move toward the small seaside community of 13,000 south of Santa Barbara. But high temperatures, low humidity and a steep, dry landscape that hadn’t felt flames in more than 30 years drew the Thomas Fire to the coast.

    I looked at the maps and we both came to the conclusion that Carpinteria would be fine, don’t worry. Sure enough, that night it burned into Carpinteria and they had to evacuate the town.
    — Tim Chavez, Cal Fire assistant chief

    The sudden shift put the town in peril. Some 300 residents were evacuated in the middle of the night as the blaze moved into the eastern edge of Carpinteria.

    In all, the fire, which was sparked by power lines downed by high winds, burned for nearly 40 days, spread across 281,000 acres, destroyed more than 1,000 homes and other buildings and killed two people, including a firefighter. At the time, it was the largest wildfire in California’s modern history; now, just six years later, it ranks at number eight.

    The unforeseen assault on Carpenteria was an I-told-you-so from nature, the sort of humbling slap-down that fire behavior analysts in California are experiencing more and more.

    “I’ve learned more from being wrong than from being right,” Chavez said. “You cannot do this job and not be surprised by something you see. Even the small fires will surprise you sometimes.”

    Warmer nights, drought, lack of fog alter fire behavior

    Scientists say the past 20 years have brought a profound — and perhaps irreversible — shift in the norms of wildfire behavior and intensity. Fires burn along the coast even when there’s no desert winds to drive them, fires refuse to lay down at night and fires pierced the so-called Redwood Curtain, burning 97% of California’s oldest state park, Big Basin Redwoods.

    The changes in wildfires are driven by an array of factors: a megadrought from the driest period recorded in the Western U.S. in the past 1,200 years, the loss of fog along the California coast, and stubborn nighttime temperatures that propel flames well into the night.

    Higher temperatures and longer dry periods are linked to worsening fires in Western forests, with an eightfold increase from 1985 to 2017 in severely burned acreage, according to a 2020 study. “Warmer and drier fire seasons corresponded with higher severity fire,” the researchers wrote, suggesting that “climate change will contribute to increased fire severity in future decades.”

    “What we are seeing is a dramatic increase in extreme fire behavior,” Heggie said. “When you have a drought lasting 10 years, devastating the landscape, you have dead fuel loading and available fuel for when these fires start. That’s the catalyst for megafire. That’s been the driving force for change in fire behavior.”

    About 33% of coastal summer fog has vanished since the turn of the century, according to researchers at UC Berkeley. That blanket of cool, moist air that kept major fires out of coastal areas can no longer be relied upon to safeguard California’s redwood forests.

    Firefighters are losing another ally, too, with the significant increase in overnight temperatures. Nighttime fires were about 28% more intense in 2020 than in 2003. And there are more of them — 11 more “flammable nights” every year than 40 years ago, an increase of more than 40%.

    The upshot is that fires are increasingly less likely to “lie down” at night, when fire crews could work to get ahead of the flames. The loss of those hours to perform critical suppression work — and the additional nighttime spread — gives California crews less time to catch up with fast-moving blazes.

    Also, fire whirls and so-called firenados are more common as a feature of erratic fire behavior. The twisting vortex of flames, heat and wind can rise in columns hundreds of feet high and are spun by high winds.

    Firenados are more than frightening to behold: They spread embers and strew debris for miles and make already dangerous fires all the more risky. One was spotted north of Los Angeles last summer.

    Fires are “really changing, and it’s a combination of all kinds of different changes,” said Jennifer Balch, director of the Environmental Data Science Innovation & Inclusion Lab at the University of Colorado Boulder and a longtime fire researcher who tracks trends that drive wildfires.

    “We're losing fog. We're seeing drier conditions longer and later into the season. And so what that means for California right now is, under these record heat waves, we're also now butting up against the Santa Ana wind conditions,” she said. “I think we're loading the dice in a certain direction.”

    A fire behaviorist’s day

    Among the many specialists at work are fire behavior analysts, who are responsible for predicting a fire’s daily movements for the incident commander. As a fire rages, Cal Fire analysts get their information in an avalanche of highly technical data, including wind force and direction, temperature and humidity, the shape and height of slopes, the area’s burn history, which fuels are on the ground and, in some cases, how likely they are to burn.

    Gleaned from satellites, drones, planes, remote sensors and computer mapping, the information is spat out in real time and triaged by the fire behavior analyst, who often uses a computer program to prepare models to predict what the fire is likely to do.

    That information is synthesized and relayed — quickly — to fire bosses. Laptops and hand-held computers are ubiquitous on modern firelines, replacing the time-honored practice of spreading a dog-eared map on the hood of a truck.

    “On a typical day I would get up at 4:30 or 5,” said Chavez, who has served as a fire behavior analyst for much of his career. “We get an infrared fire map from overnight aircraft, and that tells us where the fire is active. Other planes fly in a grid pattern and we look at those still images. I might look at computer models, fire spread models, and the weather forecast. There’s other data that tells you what fuels are in the area. You plug all that in to see where the fire will be 24 hours from now.”

    At the fire camp’s 8 a.m. briefing, “you get two minutes to tell people what to watch out for,” he said. Throughout the day, Chavez says he monitors available data and hitches a helicopter ride to view the fire from the air. At another meeting at 5 p.m., he and other officers prepare the next day’s incident action plan. Then he’s back to collating more weather and fire data. The aim is to get to bed before midnight.

    The importance of the fire behavior analyst’s job is reflected by the sophistication of the tools available: real-time NOAA satellite data, weather information from military flights, radar, computer-generated maps showing a 100-year history of previous burns in the area as well as the current fuel load and its combustibility, airplane and drone surveillance and AI-enabled models of future fire movements. Aircraft flying over fires provide more detail, faster, about what’s inside fire plumes, critical information to fire bosses.

    In California, the National Guard is entering the fourth year of an agreement to share non-classified information pulled from military satellites that scan for heat signatures from the boost phase of ballistic missiles. When those heat images are associated with wildfires, the agency’s FireGuard system can transmit detailed information to Cal Fire every 15 minutes.

    Meteorologist Craig Clements, director of the Fire Weather Research Laboratory at San Jose State University, has chased fires for a decade.

    “We can pull up on a fire, and the radar starts spinning and you’re peering into a plume within four minutes,” Clements said. “It gives us information about the particles inside, the structure of it.”

    Fire behavior decisions are not totally reliant on outside data inputs. Seasoned fire commanders remain firmly committed to a reliable indicator: the hair on the back of their necks.

    Fireline experience and hard-earned knowledge still counts when formulating tactics. But it’s a measure of how norms have shifted that even that institutional knowledge can fail.

    Future of firefighting: AI crunches billions of data points

    Perhaps the biggest leap is applying artificial intelligence to understand fire behavior. Neil Sahota, an AI advisor to the United Nations and a lecturer at UC Irvine, is developing systems to train a computer to review reams of data and come to a predictive conclusion.

    The idea is not to replace fire behavior analysts and jettison their decades of fireline experience, Sahota said, but to augment their work — and, mostly, to move much faster.

    “We can crunch billions of different data points in near real time, in seconds,” he said. “The challenge is, what’s the right data? We may think there are seven variables that go into a wildfire, for example. AI may come back saying there are thousands.”

    In order for their information to be useful, computers have to be taught: What’s the difference between a Boy Scout campfire and a wildfire? How to distinguish between an arsonist starting a fire and a firefighter setting a backfire with a drip torch?

    Despite the dizzying speed at which devices have been employed on the modern fireline, most fire behavior computer models are still based on algorithms devised by Mark Finney, a revered figure in the field of fire science.

    Working from the Missoula Fire Sciences Laboratory in Montana, Finney has studied fire behavior through observation and, especially, by starting all manner of fires in combustion chambers and in the field. In another lab in Missoula, scientists bake all types of wood in special ovens to determine how fuels burn at different moisture levels.

    Still, Finney is unimpressed by much of the sophisticated technology brought to bear on wildfires as they burn. He said it provides only an illusion of control.

    “Once you are in a position to have to fight these extreme fires, you’ve already lost,” he said. “Don’t let anybody kid you, we do not suppress these fires, we don’t control them. We wait for the weather.”

    The Missoula research group developed the National Fire Danger Rating System in 1972, which is still in place today. Among the fire behavior tools Finney designed is the FARSITE system, a simulation of fire growth invaluable to frontline fire bosses.

    Don’t let anybody kid you, we do not suppress these fires, we don’t control them. We wait for the weather.
    — Mark Finney, Missoula Fire Sciences Laboratory

    Finney and colleagues are working on a next-generation version of the behavior prediction system, which is now undergoing real-world tests.

    “This equation has an awful lot of assumptions in it,” he said. “We’re getting there. Nature is a lot more complicated. There are still a number of mysteries on fire behavior. We don’t have a road map to follow that tells us that this is good enough.”

    By far the best use of the predictive tools that he and others have developed is to learn how to avoid firestarts, he said, by thinning and clearing forests to reduce threat.

    “I would love to tell you that the key to solving these problems is more research. But if we just stopped doing research and just use what we know, we’d be a lot better off.”

    Still, research about fire behavior races on, driven by the belief that you can’t fight an enemy you don’t understand.

    Mike Koontz is on the frontlines of that battle, tucked into a semicircle of supercomputers. Koontz leads a team of researchers in Boulder, Colo., studying a new, volatile and compelling topic: California megafires.

    “We began to see a clear uptick in extreme fire behavior in California since the 2000s,” said Koontz, a postdoctoral researcher with the Earth Lab at University of Colorado Boulder. “We keyed in on fires that moved quickly and blew up over a short period of time.” California is a trove of extreme fires, he said.

    Koontz is using supercomputers to scrape databases, maps and satellite images and apply the data to an analytical framework of his devising. The team tracks significant fires that grow unexpectedly, and layers in weather conditions, topography, fire spread rates and other factors.

    What comes out is a rough sketch of the elements driving California’s fires to grow so large. The next hurdle is to get the information quickly into the hands of fire commanders, Koontz said.

    The goal: if not a new bible for fighting fires, at least an updated playbook.

  • ID'd in Los Angeles County this year
    A hand holds a small vial between its pointer finger and thumb. The vial says "single dose measles, mumps, and rubella virus vaccine" it has a blue cap. The background is blurred.
    Officials recommend checking your vaccination status if you were exposed to measles.

    Topline:

    The Los Angeles County Department of Public Health has confirmed its fifth measles case of the year. The person flew into LAX on Thursday, May 14.

    Why now: The resident was traveling internationally and arrived at Tom Bradley International Terminal (Terminal B) at LAX on May 14 via Alaska Airlines Flight 1354, departing from Guatemala City. Anyone in the terminal between 6 and 8 a.m. that morning may have been exposed.

    What's next: Public health officials say passengers seated near the infected traveler will be notified by their respective local health departments. They are working to find additional exposure sites that the traveler visited in L.A. County.

    What you should do: If you were at LAX during that time, officials say you should check your vaccination status.

    Those exposed could be at risk of developing measles one to three weeks after exposure. If you do develop symptoms of measles, officials advise you to call your doctor as soon as possible, and before going in, since it’s so contagious.

    Symptoms include: High fever, cough, runny nose, red and watery eyes, and a rash three to five days after other symptoms. 

    Vulnerable populations: If you’re pregnant, have an infant, have a weakened immune system or are not immunized, call your doctor right away after possible exposure, even if you don’t have symptoms.

    The bigger picture: According to the CDC, there have been 27 new outbreaks of measles across the United States this year, with 1,893 cases so far.

    In 2025, there were 48 outbreaks across the U.S., with a total of 2,288 confirmed cases. Nine were in Los Angeles County.

    Data center builders don’t tell the public how much water they use, according to a new report — and the industry is encroaching into water-stressed and vulnerable communities.

    Why now: The report, by the think tank Next10 and researchers at Santa Clara University, finds that planned data centers are spreading to regions reliant on overtapped groundwater and strained surface water, with potentially major effects in the Central and Imperial Valleys.

    Why it matters: The researchers found that a patchwork of state, federal and local policies allows data center operators to avoid publicly disclosing their actual water use.

    Data center builders don’t tell the public how much water they use, according to a new report — and the industry is encroaching into water-stressed and vulnerable communities.

    The report, by the think tank Next10 and researchers at Santa Clara University, finds that planned data centers — the ganglia of artificial intelligence — are spreading to regions reliant on overtapped groundwater and strained surface water, with potentially major effects in the Central and Imperial Valleys.

    But, reinforcing previous studies, the researchers found that a patchwork of state, federal and local policies allows data center operators to avoid publicly disclosing their actual water use.

    California lawmakers tried to address this last year, but California Gov. Gavin Newsom vetoed the measure. Now, the legislature is trying again, with bills mandating disclosures about water use and planning.

    “We have this huge build out, and we have very little data,” said Irina Raicu, who directs the Internet Ethics program at the Markkula Center for Applied Ethics at Santa Clara University.

    Paired with California’s precarious water supplies, Raicu said, “It’s just not a good combination.”

    Shaolei Ren, an expert on the environmental impacts of AI at UC Riverside who was not involved in the study, said the findings point to a much broader problem.

    “Limited publicly available information about data center water use makes it difficult for communities, water providers and researchers to have meaningful public discussions and responsibly assess power-water trade-offs,” Ren said in an email.

    Murky water use 

    Few environmental impact reports for California’s data centers were publicly available online, the researchers found.

    Raicu and co-author Iris Stewart-Frey, a professor of environmental science, went looking for the reports, meant to assess and disclose a project’s impacts for both nature and people under the landmark California Environmental Quality Act.

    They found almost none. The ones they did find were largely for facilities in the city of Santa Clara.

    Through interviews with planning officials, they discovered that projects can slip through with little environmental review if they fall under certain size or water use thresholds, or if they meet a city or county’s criteria for other approval pathways. These include something called ministerial approval, which requires planning agencies to approve a project that meets local zoning and other standards.

    Even for data centers that undergo more stringent environmental scrutiny, the researchers found that documentation is rarely available to the public.

    In the few cases the planning documents were posted publicly, the information — on the data center’s owner or operator, size, type of cooling system, the amount of water used, whether it’s recycled or potable — was often “missing, contradictory, or vague,” the report said.

    The researchers said they contacted water providers in areas where data centers cluster, seeking usage data. None responded.

    A shift to vulnerable regions

    California’s data centers mostly cluster in the south San Francisco Bay Area and the city of Los Angeles, with smaller concentrations in Sacramento and San Diego.

    But the report noted large, planned projects in rural and less affluent regions — like in Santa Clara County’s Gilroy, as well as in the heavily agricultural Imperial Valley.

    “They need a bunch of cheap land,” Raicu. “If we’re not careful, they will end up being pitched, very convincingly, to communities that have real needs — without enough attention being paid to the water part.”

    Khara Boender, director of state policy for the Data Center Coalition, which has opposed bills mandating more granular water-use reporting, said in an email the industry is “committed to being a good neighbor.”

    Boender argues that data centers collectively “used significantly less water than other essential industries in 2025, including the agriculture, power, food and beverage, and semiconductor sectors,” but the coalition offers no data to back that up.

    Collective use matters less than local impacts in a state where each community has its own mix of water supplies and strains, according to a previous study published by a team at UC Berkeley.

    Whether data centers use a lot or a little water relative to agriculture or other industries, “what matters most is the scale of new local use compared to available local supply,” the Berkeley team concluded earlier this year. “Unfortunately, this picture is clouded by data deficiencies.”

    In this week’s report, the Santa Clara University team drilled into those local supplies and community vulnerabilities to anticipated expansion.

    “We’re at the brink of this happening in California,” Stewart-Frey, the environmental scientist, said. Her report, she added, isn’t advocating against data centers. But “communities should know what they’re getting themselves into.”

    Debates over proposed data centers are erupting in a Kern County desert community with dwindling groundwater and in the hot Imperial Valley, which draws from the strained Colorado River

    Monterey Park residents in the San Gabriel Valley successfully opposed one data center project over environmental concerns and inadequate information and secured an upcoming vote on a citywide ban.

    In a letter to city officials, a representative for the developer dismissed opponents as “rage-baiting an uninformed mob to pressure your decisionmaking.”

    Raicu pushed back. “If those communities are uninformed about the issue — whose fault is that? Who should be informing the people so that you don’t have this kind of pushback, if there is no need for it?”

    New laws v. Big Tech

    Last year, Assemblymember Diane Papan, a Democrat from San Mateo, authored a bill requiring data center operators to report estimated or actual water use to their water supplier when seeking or renewing a business license or permit.

    Gov. Gavin Newsom vetoed the measure amid industry pressure, saying he was “reluctant to impose rigid reporting requirements about operational details on this sector without understanding the full impact on businesses and the consumers of their technology.”

    Now, Papan is trying again with two bills. One largely reprises last year’s measure, with additional reporting required to the city and county. The other would bar local governments from approving new or expanded data centers unless the developer discloses information about their water use and plans.

    It would also set other requirements — like prohibiting development in overdrafted groundwater basins in places like the San Joaquin Valley, unless state water managers OK it.

    “You cannot manage what you have not and cannot measure,” Papan said. “The public likes transparency, and they should.”

    Both bills cleared a key legislative chokepoint this week but face staunch opposition from the tech industry and business groups.

    “If they run out of water, guess what happens? And they can’t cool their systems — are they going to succeed?” Papan said. “To which I say, help us help you.”

    Yang and Capizzi’s long history of vending at markets taught them how isolating running a small business can be. At their market, they aim to build connections with each vendor and strategize the best timing and layout so everyone can succeed.

    “[Amazon and Barnes & Noble] are Goliath, and we’re not even David — we’re just the ant underneath David’s foot,” Capizzi said. “I think we can do what we do and try to get as many people, at our level or even smaller, to get together.”

    Weekly markets at A Good Used Book have captivated the neighborhood since its opening in October 2023, with charming names like “Sunday Funday,” “Saturday School” and “Hi-Fi Friday Night,” plus hand-drawn flyers by well-known artist Noah Harmon. Now, it’s become a weekly occurrence where LA pop-ups can display their own crafts, allowing local readers to indulge in a little more than a pocket paperback.

    Each week holds a Pandora’s box of niche snacks, crafts or trinkets you didn’t know you needed, ranging from Southeast Asian-inspired trail mix to natural incense sticks to vintage Japanese audio equipment. One week you might be enticed to adopt a kitten from a rescue booth outside, another week you might impulsively get a stick-and-poke tattoo in the back of the store.

    Nestled between Historic Filipinotown and Echo Park is a bookstore turned artisan craft space turned food market, all within 900 square feet. Every Sunday, A Good Used Book on Glendale Boulevard transforms from a retail bookstore into what they call “Sunday Funday Market.”

    On one sunny Sunday afternoon, Brandon Stanciell hand-tossed fresh pizza dough on the sidewalk outside the bookstore. His 2-year-old pop-up, Pizza Ananda, which he named after his daughter, is an homage to her and to Italian cooking, a hobby he started during paternity leave. An hour before the market closed, Stanciell had already sold out and garnished his last pepperoni-and-hot-honey pie for one lucky customer.

    “I love that places like this allow us all to meet at once to share what we have and give it to the community around us,” Stanciell said.

    For the owners, building a community market is about deepening relationships with the people who walk through their doors. In an increasingly digital landscape, it is also a reciprocal partnership among local businesses.

    “A lot of people talk about community building nowadays as a marketing strategy,” Capizzi said. “But I think the actual community building comes from talking to each vendor and each customer and being a consistent presence in the neighborhood.”

    While customers browsed for unique titles, Gerin del Carmen worked her booth of ceramic dishware, oyster-shaped trinket holders and vases resembling miniature boxes. As a ceramicist, del Carmen draws from her Filipino heritage, including the Balikbayan boxes that represent immigrants sending gifts to family in the Philippines.

    “Sharing the community and your space is such a big deal. This is not a huge, gigantic Barnes & Noble store,” del Carmen said. “It has so much foot traffic, and the fact that [the owners] are setting up and sharing the space once or twice a week with other vendors and other artists is huge.”

    Yang and Capizzi may think of themselves as an “ant underneath David’s foot,” but A Good Used Book is building a colony of vendors, rooted in community.

    Topline:

    Food halls make for an easy, affordable place to satisfy cravings — especially in SoCal, where diverse selections of dishes reign supreme.

    Why it matters: These spaces fill a void much deeper than our appetites. They bring new life to old storefronts, factories or even airfields, and can offer a way to keep dollars within the community by becoming a hub for local businesses.


    Read on... to learn about our recommendations for four food halls in L.A. and O.C.

    Whether you and your friends are looking for a brunch spot to cater to everyone's palates, or taking a trip to the historic Grand Central Market, food halls make for an easy, affordable place to satisfy cravings — especially in SoCal, where diverse selections of dishes reign supreme.

    But these spaces fill a void much deeper than our appetites. They bring new life to old storefronts, factories or even airfields (see list below), and can offer a way to keep dollars within the community by becoming a hub for local businesses.

    With that said, here's a short list of food halls where you'll get more than just a killer meal.

    For good vibes

    520 Whittier Blvd., Montebello
    Sunday and Tuesday through Thursday, 11 a.m. to 9 p.m.; Friday and Saturday, 11 a.m. to 10 p.m. Closed Monday.

    BLVD MRKT is an open-air food hall in downtown Montebello that feels like a party. The 8,500-square-foot space currently has five eateries, or "concepts" as they're known in the restaurant industry, and hosts live DJs every Friday night and Sunday during brunch. They also host Open Vinyl Night on the second and forth Tuesday of every month, where patrons get $2 off beers and margaritas from Alchemy Craft if they bring a vinyl record to be played in the BLVD courtyard.

    The space is pet-friendly and has growing concepts like Los Taquero Mucho, which offers classic al pastor, grilled chicken and slow-cooked carnitas tacos, as well as specialty flavors like vegan tacos with whiskil sautéed in coconut milk, and Pork Belly Cochinita Pibil Tacos, perfect for those who crave crispy, slow-roasted pork with a hint of sweetness.

    Los Taquero Mucho participates in BLVD's incubator program, run by co-founders Barney and Evelyn Santos. The program offers mentorship to local entrepreneurs until they can set up shop permanently.

    BLVD MRKT is part of the couple's commercial real estate development firm, Gentefy. Its mission is to invest in retail and hospitality projects that ignite economic development and revitalization in Black and brown neighborhoods.

    "Blvd Mrkt is our first project," Barney Santos wrote in a text message. "It was our social proof to prove to banks, investors and cities that a socially conscious business model could exist in a traditionally overlooked area."

    VCHOS Pupuseria Moderna also has a spot in the BLVD courtyard, offering handmade pupusas with filling choices such as shrimp with spinach and cheese, and tender beef birria with a side of consommé, onions and cilantro. Coffee lovers can get an Oaxacan Mocha at Cafe Santo, or stop by Cold Pizza for a wood-fired slice.

    Rodeo's menu choices make it well-suited for a casual weekend brunch. At its entrance sits Here & There, where you can grab a coffee or matcha latte, or try one of their signature drinks like the Iced Vienna, a combination of milk with caramelly demerara sugar and your choice of matcha or espresso, topped with sweet cream and garnished with sea salt. The result is a drink that's smooth and not too sweet.

    Eggyo, a recent addition to Rodeo, offers Korean corn dogs and fluffy egg sandwiches on crispy, house-baked milk bread. Try the bulgogi option with spicy mayo for a savory kick. If you crave a cocktail, venture over to CAPO, which also serves craft beer. Or just sit on one of their sun-filled patios while you decide what to try.

    This space currently has a mix of 14 food concepts and two retail shops. Patrons can enjoy local favorites outside their flagship locations, like the Joe's Special bagel sandwich from Cassidy's Corner Cafe, with bacon, egg and the star of the show — tangy jalapeño cream cheese. Fans of spice can try Jay Bird's Nashville Hot Chicken, which offers chicken sandwiches and tenders, and Blazin' Fries, all with six levels of heat.

    There are meeting rooms to rent starting at $25 an hour. It's a space where locals can bring their laptop to work or study, or have a long conversation with a friend, with bites from six acclaimed restaurants.

    At the Mercado, visit Holbox for Michelin-starred seafood dishes like Erizo — velvety sea urchin laid atop a bed of tender scallop ceviche. The combination is fresh, flavorful and oceanic. Tip: If you can swing it, come on a weekday to avoid a long line, or order ahead.

    For something sweet, walk over to Oaxacacalifornia Cafe & Juice Bar for a Spicy Pineapple Juice with a gingery kick, or go for the classic pairing of Hot Oaxacan Chocolate, made with your choice of water or milk, and light-as-air conchas crowned with a solid layer of vanilla or chocolate streusel.
