The Brief

The most important stories for you to know today
  • Cool materials may help us adapt to a hotter norm

    Kids play on a basketball court at a park in Pacoima that's been coated with "cool paint" that lowers surface temperatures and may help cool the community as a whole.

    Topline:

    "Cool" coatings on streets and roofs can dramatically reduce surface temperatures and potentially help cool neighborhoods. A pilot project in Pacoima aims to determine by how much.

    Why it matters: While planting trees, shade and green space as well as improving housing are long-term solutions, cool pavement can be installed quickly and easily and have an immediate effect. As extreme heat rapidly worsens, L.A. and many cities are investing in it. But the technology is new and it's unclear how much it can help.

    Caveats: The type of cool coating matters. Research out of UCLA found the asphalt-based reflective coatings the city of L.A. has used can actually make it hotter immediately above the surface … where people are. The coating in this area of Pacoima is acrylic-based, and preliminary research shows it doesn’t have that impact.

    As temperatures climbed on a recent afternoon in Pacoima, a local park bustled. Kids splashed in the rec center pool and shot hoops on a basketball court. Adults relaxed in the shade of trees. A vendor sold ice cream.

    Are Cooling Materials A Solution To Fight Urban Heat?

    Nine-year-old triplets Enam, Efemor and Eyako come to the park pretty much every day in the summer with their mom.

    Efemor tried to catch a breeze on a playground swing.

    "We saw it was 102, and to me that's pretty hot and doesn't make me want to do much," Efemor said.

    Already in their short lives, Enam said they’ve noticed a change in the weather. 

    "I feel like it gets pretty hotter, like kind of every year," she said. The last eight years have been the hottest on record globally, according to the World Meteorological Organization.

    Cool pavement in one of L.A.'s hottest neighborhoods

    Pacoima is one of the hottest neighborhoods in L.A. And the climate crisis is pushing average temperatures higher, and driving longer and hotter heat waves. All our buildings and pavement only make it worse.

    Last year, grassroots group Pacoima Beautiful partnered with roofing company GAF to test how “cool pavement” might help. They painted 10 square blocks of streets, the park’s parking lot and basketball court, as well as an elementary schoolyard.

    Cool pavement is among some types of materials that reflect solar radiation, instead of absorbing it. These coatings can also be used on rooftops and other surfaces exposed to the sun’s heat.

    Eliot Wall, GAF’s cool pavement project director, pointed a thermometer at the ground.

    "Here it's 132 degrees on this coated surface," he said.

    We walk to an uncoated portion of the road. It’s 10 degrees hotter on regular old asphalt.

    Why heat doesn't just go away

    But cooler surface temperatures don’t automatically mean cooler communities, said V. Kelly Turner, a UCLA heat researcher.

    "You can't make heat go away," Turner said. "You can only transfer that energy."

    Her research found that cool pavement applied in L.A. may dramatically reduce surface temperatures, but can actually increase the air temperature just above the surface, where people are.

    If the goal is cooler surface temperatures on a sidewalk so children or pets don't burn their feet as easily, a reflective coating might make sense. But if the goal is to reduce the heat load on people, planting trees or providing shade — from either trees or structures — could be more effective, Turner said.

    "Shade cools surfaces as well and it also has a much larger effect on cooling the body," said Turner.

    Cool pavement is no silver bullet, but it’s relatively quick and cheap to apply and can have an immediate effect (GAF paid for the project in Pacoima). Wall said GAF's proprietary blend of acrylic-based rather than asphalt-based cool paint doesn’t have that same heating impact above the surface.

    It's also been tested by the L.A. Bureau of Engineering for grip in wet weather and performs just as well as normal asphalt. And GAF designed it to be more durable than traditional asphalt coatings, according to the company.

    GAF uses a modified electric golf cart to take all kinds of temperature readings, from surface to air to what's called mean radiant temperature, which is an ideal measurement for how humans will physically experience heat — and the main measurement used in Turner's study identifying heat load.

    But preliminary research by GAF — that has yet to be confirmed by outside researchers — found the coatings helped cool the air temperatures for the 10-block area by three degrees during the record-long and hot heat wave in early September 2022.

    "What we're seeing is the overall neighborhood effect that the air itself is cooler and that's even actually shifting with the wind downstream," said Wall.

    GAF research found that during some of the hottest days, the area with cool paint was 3 degrees cooler than other areas, and wind even helped spread that cool air around.

    What's next in Pacoima

    Melanie Paola Torres, a community organizer with grassroots group Pacoima Beautiful, which leads the community engagement piece of the project, said community members are feeling a difference — and want more.

    "We’ve seen things that do work, so we just keep hoping to add and stack onto that and really create a climate-resilient community," she said.

    Back at the playground, the triplets and I carry out our own science experiment. (I did get their mother’s permission.)

    The rubber underneath the swings and play structure measures at 172 degrees. Then we run over to the basketball court, bright with Dodger blue “cool paint.” Its surface is 40 degrees cooler.

    Eyako sums up our findings.

    "It used to be really hot like fire, and now it's like cooler and it's much more better for people to play basketball here," he said.

    Still, cool coatings, though promising, require further research.

  • City installs speed cameras, how they'll work

    Topline:

    Automated speed cameras have arrived in Long Beach, and they’re scheduled to begin issuing tickets soon.

    Why now: The cameras are part of a state-authorized pilot program to see if writing automated speeding tickets can make roads safer.

    The backstory: Long Beach has seen a surge of deadly crashes in recent years and was picked as a pilot city after the mayor and city officials lobbied for the chance to install cameras.

    Read on... for more on when the cameras will start and where they are.

    This story first appeared on Long Beach Post.

    Long Beach has seen a surge of deadly crashes in recent years and was picked as a pilot city after the mayor and city officials lobbied for the chance to install cameras.

    When they start

    Crews began installing the speed cameras this week. Nearby signs will warn drivers, said Joshua Hickman, director of Public Works. The cameras will start issuing warnings for 60 days before citations start.

    The warning period is expected to start in October; then citations would start going out in December, Hickman said.

    How they work

    The cameras capture only the rear license plates of drivers speeding 11 mph or more over the posted speed limit. Based on that license plate information, a citation will be issued to the address where the car is registered.

    License plate data is kept within the Public Works Department and not shared with any law enforcement agencies, including Long Beach police, Hickman said.

    Where they are

    Half of the cameras are on streets where deadly or severe crashes have occurred most often. The other half are going in school zones or in areas where street racing is a problem.

    You can find an interactive map of the speed camera locations here.

    How much is a citation

    Citations range from $50 to 500 based on speed.

    Speed Over LimitFine Amount
    11-15 mph$50
    16-25 mph$100
    26+ mph$200
    100+ mph$500

    If a driver does not receive any warnings during the 60-day warning period, then the first speeding offense will result in a warning. After that, they will get a citation with a fine.

    Payment is due within 30 days, but payment plans and diversion programs are available.

    You can find more info on those here.

    How will the money be spent?

    The city anticipates half of the speeding ticket revenue, roughly $2.5 million, will cover the costs of running the camera program.

    The other half will be spent on traffic-calming measures in neighborhoods where traffic engineers determine they’re needed most. The state law authorizing the pilot program says the money can’t be spent on anything else.

    Safety measures could include crosswalks, no-turn-on-red signs and speed humps. The city has received an influx of requests from residents asking for some sort of safety measure in their neighborhood since the start of the year.

    Traffic deaths

    Residents have said they’re fed up with dangerous streets, and the city is trying to respond.

    Last year, Long Beach recorded its deadliest year on the roadways in more than a decade – 53 fatal traffic collisions.

    Earlier this year, Long Beach City Council directed the Public Works Department to hire third-party contractors to speed up their ability to install quick-build safety measures.

    But traffic deaths this year have kept up the pace. At this time last year, the city had tallied 35 traffic deaths. As of Friday, this year’s total is at 33.

    State pilot

    Long Beach is able to install speed cameras thanks to a 2023 state bill that approved a five-year pilot for Long Beach as well as six other cities.

    The city was allowed to install speed cameras immediately after the bill passed and had until Jan. 1, 2027, to begin the pilot.

    Street safety advocates have criticized Long Beach for its delayed rollout compared to other cities.

    Success in other cities

    San Francisco installed 33 speed cameras last October and reported a 72% reduction in speeding after six months of citations.

    In Oakland, 18 speed camera locations saw a 70% drop in speeding drivers, on average.

    Los Angeles and Glendale have yet to deploy their speed cameras.

    Potential expansion to PCH

    A state bill currently on Gov. Gavin Newsom’s desk would allow Long Beach to install two more speed cameras on Pacific Coast Highway.

    If signed, the cameras could be installed as soon as Jan. 1 and would follow the same rules as the other cameras.

    PCH is a state route, meaning it was not included in the state pilot program because it’s not controlled by the city of Long Beach.

    State Sen. Lena Gonzalez, who authored the bill, said PCH accounts for about one-fifth of the city’s traffic deaths despite covering less than 1% of the city’s roadways.

  • International student work authorizations paused

    Students at UCLA on the Janss steps. The university has paused issuing work authorizations to international students.

    Topline:

    An onslaught of Trump administration directives targeting international students are leaving some of them feeling worried and lost. And experts warn these could have adverse effects on U.S. industry and global growth.

    What happened: The Department of Homeland Security says they have put some colleges and universities “on notice” after a memo sent out in August warned that they have “observed a rise in Curricular Practical Training (CPT) authorizations that appear to violate regulatory requirements which permit CPT only where the training is an integral part of an established curriculum.”

    CPT is unpaid or paid work, like internships, international students do to gain real world experiences.

    Why it matters: Following the memo from the department, several universities including the University of Southern California, UCLA and UC Berkeley have paused or required additional information to determine if work experience is a requirement for a particular degree program.

    Students react: For students, this is causing uncertainty: “ It came as a surprise to all the international students. We were not aware of it and there is a lot of tension among the international students,” said one USC student.

    The Department of Homeland Security says they have put some colleges and universities “on notice” that they could be in violation of federal rules that dictate work opportunities for international students.

    The directive has left some of those students feeling worried, as their schools pause opportunities to work in the United States.

    And experts warn that it could have adverse effects on U.S. industry and global growth.

    What does DHS say?

    In late August, the Student and Exchange Visitor Program, part of the Department of Homeland Security, issued a statement stating that they have “observed a rise" in violations related to Curricular Practical Training.

    CPT is paid or unpaid work that students do as part of their degree program, like an internship. The administration says regulatory requirements permit CPT only where the training is “an integral part of an established curriculum.”

    In a written statement, an unnamed DHS spokesperson told LAist, “Nothing about these regulations has changed. However, schools and employers should consider themselves on notice: under President Trump, abuse of this generous system will no longer be tolerated.”

    LAist reached out to DHS for the percentage increase in CPT violations and specifically asked for data related to Southern California schools. We have not received an answer.

    How have local universities responded?

    Following the memo from the department, several universities including the University of Southern California, UCLA and UC Berkeley have paused or required additional information to determine if work experience is a requirement for a particular degree program.

    In a written statement to LAist, a spokesperson for the UCLA Dashew Center said, “UCLA has paused certain Curricular Practical Training authorizations while the university reviews recent federal guidance and determines next steps. UCLA is communicating directly with students who have affected CPT applications and remains committed to supporting our international students as we navigate these changes.”

    Why it matters

    For students, this is causing uncertainty.

    “It came as a surprise to all the international students. We were not aware of it and there is a lot of tension among the international students,” said Nitesh, a student from India at USC. He asked that we only use his first name for fear of repercussions from speaking to the media.

    Those who applied for CPT authorizations after Aug. 23 at USC now are in limbo waiting to see if their applications will be approved.

     ”It is a real industry exposure to us when it comes to learning,” Nithesh said about the CPT component. “We definitely get lots of learnings and value from classes and by doing projects, but CPT is a way for us to understand what happens in the industry and keep us up to date.”

    Nitesh, who took out an $85,000 loan to come to the U.S. for his degree program, said he would have reconsidered coming here had he known about these regulations ahead of time.

     ”Because there is a lot happening and nobody has clarity, so there is a lot of ambiguity, and we are just waiting for the right information to come in,” he said.

    International enrollment impact

    The memo is the latest in a string of directives targeting international students. Earlier this year, the Trump administration announced new rules limiting how long international students can remain in the country, as opposed to remaining in the U.S. for as long as it takes to complete their degree program.

    Santa Monica College has seen a drastic drop in international student enrollments: In fall 2016, the community college had more than 3,500 international students enrolled; that number has dropped to less than 1,600 this year.

    Grace Smith, a spokesperson for Santa Monica College said, “In recent years, several interconnected federal restrictions continue to exert pressure on international enrollment and are likely to impact future enrollment cycles.”

    Declining international student enrollment has a “significant impact on the college’s fiscal outlook,” Smith said as international student enrollment accounts for about 8% of the college’s unrestricted revenue.

    Caltech’s president Ray Jayawardhana told LAist’s AirTalk program that he came to the U.S. as an international student from Sri Lanka.

    “ Growing up in Sri Lanka, I thought of universities like Caltech in the United States as beacons on a hill,” he said. “They really were beckoning the best and the brightest from around the world, and I think it behooves us to preserve that attraction, preserve that draw, so that this country and the world at large benefits from students, from researchers, from scholars.”

    While the uncertainties are “discouraging,” Jayawardhana said, Caltech is seeing “continued interest that's as strong as ever.”

    Earlier this year, Ray Jayawardhana, astrophysicist and former provost of Johns Hopkins University, was named the 10th president of Caltech. Along with being the face of the school's operations, he is also set to oversee NASA’s Jet Propulsion Laboratory.

    Hits to the U.S. economy

    Rachel Banks,  senior director for public policy and legislative strategy at NAFSA: Association of International Educators, said the current climate for international students is the “most difficult and most challenging” it has been since World War II.

    “Having gone through the first [Trump administration], there were certain expectations of what we might see coming,” she said. “What I think was unexpected was the severity and degree to which we saw the Trump administration make moves specifically with respect to international students.”

    Banks says her organization projects that the loss of around 111,000 international student enrollments could cost the U.S. economy $3.4 billion and nearly 4,000 jobs. California’s economy could see a hit of about $500 million because of declining enrollment.

    The volume of visa revocations, particularly for students involved in campus protests for Palestinian rights, was “unprecedented,” she said. The State Department’s move to pause on interviews for visa applications and renewals was also something that hadn’t happened at this scale before, Banks said. And the new visa limits for international students, she said, is “incredibly disruptive” and takes the decision making away from students and universities.

    The new memo about CPT authorizations adds to the uncertainty, she said.

    Following World War II, the government put a lot of emphasis into fostering and developing our higher education system, Banks said, which allowed universities “to attract the best and brightest talent and that has led to the numerous innovations and achievements that we've been able to see come out of the United States.”

    That talent, she said, will now look to go to other countries more favorable to international students.

    In less than two years, the Olympics and Paralympics will take over Los Angeles for the summer of 2028, temporarily transforming the city and the region around it. To answer what that will mean for everyday Angelenos, LAist is launching our Olympics Monday to spotlight our ongoing coverage of the Games.

    The backstory: Hosting the world’s largest sporting event will mean commandeering a fleet of nearly 2,000 public buses, reserving stretches of freeway lanes just for Olympics traffic flow, deploying thousands of law enforcement officers across venues, taking over UCLA and USC to make way for athletes and journalists, and flooding Southern California with millions of fans.

    Why it matters: Los Angeles residents have more at stake than just inconvenience, ticket prices and traffic. The city of L.A. is the financial backstop for the Olympics, meaning taxpayers will pick up the tab if LA28, the private organization planning the Games, runs a deficit.

    What will everyday Angelenos get out of all this? That depends. And it’s the question LAist is dedicated to answering every Monday as we spotlight our ongoing reporting on the 2028 Olympic and Paralympic Games.

    Los Angeles residents have more at stake than just inconvenience, ticket prices and traffic. The city of L.A. is the financial backstop for the Olympics, meaning taxpayers will pick up the tab if LA28, the private organization planning the Games, runs a deficit.

    That makes every plan for the execution of the 2028 Games hugely important for the city — from how L.A. pens agreements with LA28 on reimbursement for city services to whether or not the federal government will pay for the enormous cost of policing the mega-event.

    L.A. has hosted the Olympics before — first in 1932 and again in 1984. Both times the Games turned a profit — a rarity for a global event that has gained a reputation over the decades for leaving cities with debt and empty stadiums.

    Local officials say they’re confident L.A. can pull off a third Olympic Games (and its first-ever Paralympics), pointing out that hosting will not require building any new sports venues.

    Still, there’s plenty to watch, including how temporary construction will turn existing venues into Olympic competition sites, where billions in contracts for things like cleaning and construction will go and whether that money will stay local, and how the expansion of the L.A. Convention Center could affect its role as an Olympic venue.

    And there are the ways the Olympics and Paralympics could influence the lives of L.A.’s most vulnerable. Researchers estimate that close to 6,000 unhoused people live within a mile of Olympic venues in L.A. County, and could be removed due to security requirements tied to the Games. Others worry about the enhanced police presence that is guaranteed to accompany Olympic and Paralympic competitions, and what the Trump administration’s involvement in planning could mean for the city.
