The Brief

William Mullholland is often hailed as the man who brought water to Los Angeles, but there’s an earlier group Angelenos owe flowers to: The original founders of L.A., and the Zanja Madre.

The system of zanjas — Spanish for trench or ditch — was the city’s first irrigation network that brought water from the L.A. River to people’s homes and fields.

How the ditches began

For the 44 pobladores who came from New Spain (modern Mexico) to settle in today’s downtown, every drop of water was liquid gold. Having quick access to water helped sustain life and raised crops for food.

When the pueblo of Los Angeles was founded in 1781, the town was purposely located near the L.A. River. One of the first things community members built in June of that year was a water system. They joined together to carve out the first sections of a crude dirt pipeline delivering L.A. River water, the Zanja Madre (Mother Ditch), about seven weeks after settling.

They finished it in October 1781, but once the United States seized power, more zanjas were dug out. That led to the earliest industrial use of the Zanja Madre by Eagle Flour Mills in 1855, according to archeologist Marc Beherec, and more heavy use followed.

But the zanja system was delicate. The dam intake had to be repaired after rain and the ditches had to be cleaned up often for the water to reach each customer.

The Zanjero, or “water overseer,” was responsible for maintaining the system alongside a group of deputies. The position got paid better than the mayor, signifying the price tag and commodification of water.

They ensured ditches worked properly, but there was another element that made the job a big deal — they wore police badges and had the authority to arrest anyone using the water without a permit.

The city created a zanja department, but the day-to-day was still rough. At one point, zanjeros missed a day of work because all the shovels broke. Then, floods in 1884 washed out the dirt ditches and made officials go back to the drawing board. The result, costing $125,000, was to turn some of the zanjas into closed brick conduits and improve others with concrete.

The zanjas reached their prime that decade, with an estimated 6,897 acres irrigated in city limits, including vineyards and citrus farms.

By 1902, the zanja system was made up of four separate areas connecting back to the L.A. River. At its height, L.A. had 52 miles of zanja.

Why the zanjas died off

There were public-use and safety concerns.

That’s because the zanja network was a bit haphazard. Some of it was still above ground or not upgraded with cement. For example, in 1898 an association petitioned the City Council to lay pipes down on Naomi Avenue in a bid to get a “very dangerous” open zanja closed off.

In 1901, a 7-year-old boy with epilepsy fell onto an open zanja on Date Street and died.

People would bathe in these zanjas, which at some points could be 12 feet wide. Residents would go for a summer swim, dump trash, and even wash their clothes in the water they’d drink and irrigate from.

But it was William Mulholland who may have sealed the zanjas’ fate.

As superintendent of the L.A. Water Department, he wrote in a 1903 report to the board of water commissioners that “the zanja system has made its usual poor showing for the year,” making sure to show how the upkeep expenses were outpacing income.

Then, after a rainless summer, Mulholland allocated the water to the domestic drinking supply only — stripping farmers of the much needed resource — to start shutting it down.

May 1904 was the last month the city zanja department sold water. The ditches were abandoned, but portions were repurposed for a stormwater system.

After more than 240 years, the zanja system has been covered up, destroyed, and forgotten.

But every so often, parts of it come to light.

Eighteen archaeological encounters with the system have been documented as of 2022, though there have likely been more times people have come across the pipes.

But officially, crews have found it during things like Metro line work, street widenings, and building construction.

You can run into the zanja system, too. Olvera Street has a brick path extending from the fountain that represents the route of the Zanja Madre, and the Stimson House on Figueroa Street still has the above ground barriers up.

The two candidates for Los Angeles mayor, incumbent Karen Bass and challenger Nithya Raman, traded sharp jabs Wednesday night over homelessness, housing and police hiring in the first debate of the general election season.

The debate, hosted by the Sherman Oaks Homeowners Association, came as both campaigns began ramping up door-to-door canvassing in a race that’s expected to be close.

Bass, who was elected mayor in 2022, finished five points ahead of Raman in June but is considered vulnerable with unfavorable ratings at 57% in a poll taken before the primary.

Homelessness

During the debate, Raman, who represents Council District 4, said Bass had not made enough progress on the No. 1 issue facing Los Angeles: homelessness.

“You’ve been the mayor for four years and the results have not changed — the results are visible on our streets,” Raman said.

The latest homeless count showed unsheltered homelessness rose 8% from January 2025 to January 2026. The increase followed a two-year drop of 17.5%.

Bass countered that her Inside Safe program has brought thousands of people off of the streets and pointed out that Raman was head of the City Council’s Housing and Homelessness Committee until recently and therefore shared responsibility for the city’s progress on the issue.

“She has been the point person for homelessness — a very powerful position that she declared as powerful when she lost it,” Bass said.

Raman touted a 49% drop in unsheltered homelessness in her council district, which stretches from Silver Lake to Sherman Oaks.

Bass claimed Inside Safe was largely responsible for the drop.

If elected, Raman promised to conduct an audit of homelessness spending in her first six months of office and said she would fully staff a new Bureau of Homelessness Oversight to hold the city accountable for its spending on the issue.

Auditors have also flagged major problems with the handling of tax dollars by the regional L.A. Homeless Services Authority. The failures stem from poor bookkeeping and accounting of taxpayer money at the agency, which spent over $800 million in public funds last fiscal year.

Raman also promised to lobby L.A. County more forcefully than Bass for mental health, drug abuse and other social services for the unhoused.

Housing

The two also sparred over housing policy, with Raman saying the city needed more density in housing to address a severe shortage.

“This is a massive problem for the future of Los Angeles,” Raman said. “Let’s have a Planning Department that does the work to build these units, zone for these units.”

Raman said the city is “not zoned for more housing,” adding that’s why the state has stepped in with mandates for more dense housing in cities and counties across California.

Raman supported the law.

Bass opposed it.

“I do not support Sacramento telling us what to do,” Bass said. “The best way to build is to reach agreement with communities.”

Bass has billed herself as someone who would do more to preserve residential neighborhoods in the city and protect them from density. She added that 42,000 units of affordable housing were in the pipeline.

Policing

The two also tangled over the hiring of police officers.

Bass pointed to a 2020 social media post by Raman that declared “defund the police.”

“She’s irresponsible in what she talks about,” Bass said.

Raman returned the verbal jab, arguing that Bass was irresponsible for backing a big raise for police officers in 2023.

“This is about fiscal management of public tax dollars,” Raman said. "This contract gave raises to the [Police Department] that our city couldn't afford and we suffered as a result.

”We cut street lighting, we cut pothole repair — we have more potholes on our streets than we did before," she continued. “We do less graffiti removal than we did before.”

Bass has said the raises were necessary to recruit new officers and keep current officers from leaving the department.

Raman also criticized Police Chief Jim McDonnell’s response to federal immigration raids, noting he refused to enforce a state law that largely prohibited federal agents from wearing masks. The council member said she didn’t believe the chief’s response to ICE raids “met the moment,” stopping short of saying whether she would seek to remove him.

Supporting business

Bass and Raman also fought over whether the city had sufficiently supported the entertainment industry.

“We need a tax credit and advocacy in Sacramento for the kind of tax credit that Georgia has, that’s the same as New Jersey has that’s taking jobs away from here,” Raman said.

Bass said she appointed a film czar to fight for such policies and criticized Raman for doing nothing on the issue.

“You have been on the City Council for six years,” Bass said. “You’ve been at City Hall twice as long as I have. I realize you want to pitch yourself as somebody from the outside. But where were you? You’ve introduced no motion for the entertainment industry.”

Bass said Raman would not be a good mayor because she lacks support from any of her colleagues on the City Council.

“She has no support from the council members because nobody can work with her,” Bass said.

Raman said she works well with colleagues and that Bass had locked up their endorsements before she made her last-minute entry into the race.

Five news reporters and two members of the military who were invited to an event at Vandenberg Space Force Base in California were briefly detained at gunpoint by security officers who thought they were gate crashers, according to local news reports.

The incident happened Monday ahead of an invitation-only groundbreaking for a new training facility for missile operators at the federal airfield near Santa Barbara, Calif. Reporters from Noozhawk and KEYT were among those detained, and both outlets published articles detailing the detainment.

In a statement to Noozhawk, a Space Launch Delta 30 Public Affairs spokesperson called the incident a breakdown in communication.

“Vandenberg Space Force Base is experiencing an increased number of unauthorized entry attempts,” the statement said. “Every potential unauthorized presence must be treated as a legitimate threat until proven otherwise. While we recognize this may have been unsettling, the security of the base and its personnel is our priority.”

The reporters and military members were part of a convoy being escorted onto the base by uniformed public affairs staff in a government minivan when they were suddenly ordered out of their vehicles with their hands up, according to news reports.

Officers pointed guns, sirens were sounded and barricades went up at the gate entrance, KEYT reported.

The two military members assigned to the base — one enlisted and one a junior officer — were handcuffed and placed in base vehicles, while the civilians were ordered to sit on a curb, Noozhawk reported.

The reporters for outlets also including KSBY-TV and the Santa Maria Times/Lompoc Record were held for more than 30 minutes, causing them to miss the event. All were let go without further incident.

“We respect the military’s need to provide security for the base,” Tom Bolton, Noozhawk’s editor in chief, said in a statement Wednesday. “But clearly what occurred was unfortunate and unnecessary, and potentially dangerous, as firearms were drawn.”

Bolton said he hopes to have a conversation with base leadership later this week to review what happened in the hopes of preventing a similar occurrence in the future.

As severe wildfires burn across the Western U.S., California has adopted the toughest rules in the country to help protect communities from burning. Homeowners in wildfire-prone areas will be required to limit plants within five feet of their house, a protective measure that wildfire experts say can help prevent homes from igniting.
Research shows that dry, dense vegetation around buildings can cause wildfires to spread. In extreme conditions, high winds carry a deluge of tiny, burning embers far beyond the fire itself. When those embers get caught in vegetation, they can ignite, spreading flames to nearby buildings and homes.
Wednesday's vote by the California Board of Forestry and Fire Protection comes after years of debate and delays. The state originally considered rules that would have restricted all vegetation within five feet of a house, aside from well-maintained trees. That generated pushback from some communities, concerned about losing greenery in their gardens and the cost of yard maintenance.
California regulators ultimately struck a compromise about plants allowed within the five-foot zone, known as Zone Zero. Lawns, flowers and non-woody plants up to 18 inches tall will be allowed, unless they are located directly under the roofline of a house. Trees will be allowed, though branches must be trimmed five feet away from a structure. The rules will apply to new construction right away, but will be phased in for existing structures, affecting almost 2 million homes in high-risk areas.

State regulators say the rules reflect the new reality of more extreme wildfires, driven in part by rising temperatures from climate change. More than 57,000 homes and buildings have been destroyed in California in the last decade, according to state regulators.

"California's faced an existential crisis that has affected our health, that has affected our finances related to our ability to buy and sell homes, to insure homes and has put us in a very precarious place," testified Yana Valachovic of the University of California Cooperative Extension at Wednesday's hearing, who also advised the state on the new rules.

Growing tensions across Western states

California's debate reflects growing tensions across the Western U.S. about how communities should prepare for wildfires. Wildfire experts warn even fires that start in open, wildland areas can quickly become urban fires, destroying thousands of homes in neighborhoods that residents never thought were at risk, like in the 2025 Los Angeles fires. This summer, more than 800 homes were destroyed in Spokane, Wash., by three wildfires that burned through dense neighborhoods.
Across several states, homeowners in public meetings have said wildfire regulations threaten private property rights, reduce urban wildlife habitat and require costly maintenance.
"You are about to approve a set of regulations that will cost millions of California homeowners tens of billions of dollars," testified Dave Lefkowitz, president of the Mandeville Canyon Association, a community group in the Los Angeles hills. "The math is insuperable."

Vegetation management rules were recently defeated in both Oregon and Washington after strong public pushback, including misinformation that spread online. Some community groups wanted regulators to wait for more scientific research on wildfire spread.

Research shows plants can increase risk

In experiments, researchers have shown that even green plants can ignite in the dry, windy conditions of an extreme wildfire. Analyses of past California wildfires have also shown that homes with vegetation predominantly within 6 feet of the exterior walls were at higher risk of being lost. Managing vegetation also creates "defensible space" for firefighters, providing better access for defending a structure.

California has long been at the forefront of wildfire policy, pioneering regulations that other states have adopted. For almost 20 years, California's wildfire building codes have required homes to use fire-resistant materials for construction. A handful of other states recently adopted similar codes. Research shows that while there are no guarantees a house will survive a fire, protections are strongest when homeowners address both building materials and vegetation. Even in some of the most severe wildfires in recent years, some homes made it through.
California regulators say the widespread regulations are needed because voluntary measures don't provide enough protection. Communities are safest when all homeowners comply, since one home with dense, dry vegetation can spread fire to its neighbors. Insurance companies in California are also required to provide discounts to homeowners that make their homes more fire-resistant.

New rules depend on inspections

While California's new rules provide more flexibility for homeowners, some wildfire experts say they don't go far enough, given that any combustible material next to a house could pose a risk. The new vegetation rules will be enforced by local fire departments and state agencies that do home inspections every year. Those inspectors will bear the brunt of educating homeowners and ensuring compliance.
"I want the board to understand what this compromise asks of local inspection programs," Todd Lando of the Central Marin Fire Department testified at the hearing. "A clean Zone Zero is a five-minute inspection with one question: Is anything combustible within five feet? Easy for the homeowner to understand and take action on." Lando says the new rules will involve more conditional judgements by inspectors, opening up debate with homeowners that could affect compliance.

California regulators say inspectors will focus on educating homeowners at first, before compliance becomes mandatory. For existing homes, the new vegetation rules will go into effect in 2029 at the earliest.

Clemente Larraín, a doctoral student from Chile, chose his program at UCLA because it offered subsidized childcare on campus. His young daughter was enrolled for free, giving him the peace of mind to focus on his studies.

Now, the university has thrown a wrench in those plans.

In an email to families enrolled in UCLA’s Early Care and Education program, Darnell Hunt, executive vice chancellor and provost, announced two university-run childcare centers will close at the end of the 2026-27 academic year because the university has determined “the program is not sustainable.”

“ For international students, this is the worst news because we don't have networks here," Larraín said. "We don't have family. Some of us have some friends, but not too close to just trusting them to our kids.”

He earns around $3,000 a month working on campus, which he said barely covers his rent, forcing the family to dig into savings. Meanwhile, his wife is waiting for a work permit so she can start to bring in additional income.

Having to find full time care for their daughter is causing immense stress.

“ This obviously changed radically the experience of the graduate students with family at UCLA,” Larraín said.

Limited childcare options for parents

The announcement comes as a changing landscape is making it harder for parents to find childcare across California. A new report by the Center for the Study of Child Care Employment at UC Berkeley found that the rollout of a new grade for 4-year-olds in the state’s public schools is having unintended consequences for childcare businesses. Those businesses have typically cared for children 5 and under but are now losing more children to transitional kindergarten.

Between 2019 and 2025, about 1,100 preschools have closed across California.

Evyn Lê Espiritu Gandhi, an associate professor of Asian American studies at UCLA, has two children enrolled in a UCLA-run childcare center, which she said costs her around $6,000 a month — and that’s at a subsidized rate.

“Having a high-quality, safe, reliable childcare option for my children just allows me to do my job as a UCLA professor, which includes research and publishing, but also teaching and mentorship of undergraduate and graduate students,” Gandhi said. “I'm really not sure how I'll be able to do that job if I don't have adequate childcare next year.”

Gandhi said the only alternative she has for her daughter is Bright Horizons Westwood, which is part of a large chain of childcare facilities across the U.S.

“ But to be honest it doesn't have as good of a kind of teacher-child ratio as [UCLA's Early Care and Education] does, and it has a super long wait list,” she said.

LAist has reached out to the childcare facility to ask about its waitlist, teacher-child ratio and rates.

Earlier this year, Gandhi said, tuition at UCLA’s Early Care and Education program increased by 4%, Gandhi said. At the time, UCLA also announced it would eliminate “all food program services (which includes all meals, baby formula and food, milk and snacks), discontinuing support for diapers and formula, not backfilling vacant positions, and other cost reducing measures.”

After families protested, the university backed down.

‘Disconnected from its mission’

Yvonne Yang, an assistant clinical professor at UCLA in psychiatry, called it "callous and heartless," even "cruel" that the university decided to close down the childcare centers.

“It means to me that the university has completely become disconnected from its mission and basically lost its soul and is focusing only on profits,” said Yang, who is also a physician and researcher at the West Los Angeles VA Medical Center.

Yang said she’s now competing with all the families enrolled in the UCLA program for the limited childcare options available on the west side.

 ”When our kids were young and still breastfeeding, moms are welcome to just walk up to the daycare and to feed our kids during the workday, which is so much better than having to pump,” she said. “It's just a way of maintaining that connection with your kids so early in that transition.”

Having the childcare center on campus allowed her to integrate having a family life and being a professor, she said.
