The Brief

The Wallis Annenberg Wildlife Crossing has reached iconic status long before its scheduled completion in Agoura Hills by the end of 2025. Not only will it be the largest bridge of its kind for wild animals to traverse in and out of the Santa Monica Mountains, it also has a Hollywood ready mascot in the late P-22. To top it off, the bridge has inspired a Lego set — before a single mountain lion has even set foot atop the decade-in-the-making structure, whose construction has required expertise from across a range of disciplines.

"We have everyone from wildlife biologist to horticulturalist to [expertise in] engineering [and] architecture," said Robert Rock from Living Habitats, the landscape architecture firm in Chicago that is designing the entire project. "We've got a soil scientist, a soil biologist, a mycologist."

As the folks responsible for the look, feel, functionality and the ecology of the real-life crossing, it shouldn't come as a surprise that Rock and his team are also behind its humbler, and admittedly a smidge less complex, Lego counterpart.

Disclaimer: if you want to get your hands on a set, you'd first need to cast your vote for the project — 10,000 supporters are needed — before Lego would consider mass-producing the set.

The Lego idea

The idea to create a Lego version of the wildlife crossing came to Rock on a muggy August day in 2022, when he was at the zoo in Chicago with his son. To escape the heat, Rock went into the air-conditioned gift shop, and on the display case were boxes of Lego sitting next to a few animal figurines.

"I had this kind of light bulb turn on in my head and I thought, 'huh, well, maybe we could create a Lego version of the crossing just as something fun,'" Rock said.

He knew just the guy to help make it happen — an old college buddy named Martin Egemo, who has picked up Lego as a hobby, someone who's built intricate sets and models off his imagination.

"I still remember that [day]. Rob called me and he's like, 'Hey, I've got this crazy idea. What do you think?'" said Egemo, who's known in the Lego community as TMX. "I just thought, yes, this sounds awesome."

The building process

Over the next year, the team started to design and build their Lego crossing, a process that gave Egemo a crash course in the painstaking work done by Rock and Living Habitats to make the real-life crossing a reality. In exchange, he said, "I was able to help show them what Lego is capable of doing."

Like many creative challenges, the first order of business to making a Lego model from scratch was to understand the parameters.

"Honestly one of the biggest challenges was that we had to pick a scale to work in the Lego universe," Rock said.

"How big are we going to go with this? What is our true goal? What are we trying to showcase?" Egemo said.

A question Rock had posed to Egemo early in the process was whether the Denmark-based toy giant would ever consider manufacturing their set commercially. The answer from Egemo was yes, but only if they enter it into something called Lego Ideas, where 10,000 upvotes from the public will trigger an internal review of the project by the company.

One of the competition's requirements is that a submission has to be made up of under 3,000 parts. Using that as a baseline, Rock and Egemo began to figure out other aspects of the model — which details to lose, which to amplify — down to how the layers of soil should look like at the bridge's cross-section.

"Our goal isn't to show 10 lanes of the freeway. Our goal is to really showcase all the different types of plants that they are going to source that came from the area itself. So we've got to use the right colors, the right shapes and sizes," Egemo said. "What are the animals that are going to be crossing this? How can we get those animals included?"

Egemo said he made a down-and-dirty prototype. "I just took Lego and started kind of playing around," he said.

Then Rock and his team took what he did, supercharged the design and created a digital model that came with instructions on how to piece together the more than 2,300 Lego parts needed for the build.

"I think we had to go to something like 14 or 15 different vendors because of some of the colors that we used," Rock said. "You've got a lot of ochres and olive colors in the landscape. Finding those colors within the Lego world, sometimes that was a little bit challenging."

Soon, bags and bags of the bricks arrived at Egemo's home in Des Moines, Iowa. Organizing them alone — and by color — took between 10 to 12 hours.

Egemo estimated the construction itself took 16 to 20 hours over the course of about 10 days. The final product weighed in between 10 to 15 pounds, at a dimension of 23 by 10 by 8 inches.

Rock remembers seeing the finished model at Egemo's home for first time.

"In the line of work that I do, we understand scale, we understand the size of things," Rock said. "Seeing that in person, seeing the scale of it, the degree of specificity and the technical process that [Egemo] had to go through, I was kind of in shock."

The debut

The model was finished shortly before this year's P-22 Day festival held at Griffith Park in October, where Rock and Egemo had planned to unveil their miniature creation.

The two friends drove from Iowa to Los Angeles with the Lego crossing in the back of the SUV, because they had decided against shipping it. "Lego's strong, but we didn't glue anything," Egemo said.

On their way, they picked up a bunch of Lego for kids attending the festival to build their own versions of the real-life crossing.

"I'm not sure that there's a better way to tell the story of all of the passion that's bound up in this hopeful project than to imagine it through the ingenuity of a child, right?" Rock said.

As to Egemo, he finally got to see the inspiration behind his and Rock's yearlong passion project, as the Wallis Annenberg Wildlife Crossing sprouted to life from the 101.

"That was so cool driving on the freeway, seeing the construction in process, and knowing that in some way I'm a part of this, and it made it even more real," Egemo said.

Cleanup is just beginning for a contaminated industrial site in South Gate, according to U.S. Environmental Protection Agency officials who are leading the effort.

The small southeast L.A. city was built on industry — in the early 20th century it boomed with auto, chemical and other manufacturers.

That legacy also left it with three Superfund sites, areas designated by the federal government as highly contaminated with hazardous waste.

The three sites are all clustered on a large lot framed by Southern and Rayo avenues. A residential neighborhood is nearby.

“This site is less than 50 yards away from a home, so we want to make sure that we clean it to a point where we can feel confident,” said South Gate Mayor Joshua Barron.

South Gate is home to about 90,000 people, the majority of whom are Latino. The median household income is about $74,500 and the state has identified the city and surrounding communities to be disproportionately burdened by pollution and its health effects.

This site, dubbed the Southern Avenue Industrial Area, housed a screw manufacturing business for 30 years, then a carpet adhesive plant. Both businesses are now defunct and the site was designated by the federal government as a Superfund site in 2012.

The pollution at this property was compounded by pollution from companies next door.

One of the two adjacent Superfund sites was used by Cooper Drum Co., a steel drum recycling plant. A group of Cooper Drum’s former customers, including chemical manufacturers and oil companies, are paying for part of that cleanup. The other site, previously operated by an aircraft rivet and conveyor belt manufacturer, is still in the analysis and planning stages.

At the Southern Avenue site where the EPA broke ground Tuesday, analyses commissioned by the agency found widespread lead and other toxic contamination in the soil, as well as a plume of trichloroethylene, a carcinogen, in the groundwater.

Officials say the plume has not affected the deeper aquifer South Gate and other southeast L.A. cities rely on for drinking water.

In 1986, the city closed water wells contaminated by the neighboring Cooper Drum site.

“ The water is safe to drink,” said Mike Montgomery, superfund director for the EPA. “What we're trying to do is prevent it from becoming impacted.”

EPA officials estimate soil cleanup will take about two months. Groundwater cleanup planning will start in 2027 and could take a year or more. The whole effort is estimated to cost between $45 million and $60 million, primarily through federal dollars.

The summer heat may be sweltering at the moment in Southern California, but predictions about this winter’s El Niño show it could be the strongest on record.

So the LAist newsroom wants to know: What questions do you have? (You can submit below.)

We can tell you now that El Niño is a climate pattern that happens roughly every two to seven years, and is one of the most powerful drivers of the Earth’s weather.

During an El Niño event, the central and eastern tropical Pacific Ocean off the coast of South America warms to above normal temperatures. The warm ocean adds moisture and heat to the atmosphere, influencing atmospheric circulation, temperatures and precipitation on a massive scale.

El Niño typically results in mild weather in the northern United States and wetter conditions in the southern part of the country.

In Southern California, we could start to see the effects of El Niño in the late fall or early winter. Generally, those effects include significant rain and high sea levels and the consequences that come with them, such as flooding, mudslides and coastal erosion.

Forecasters say there is a more than 90% chance of a powerful El Niño event this year, and a 70% chance that it’s record-setting.

That said, uncertainty remains around how exactly this winter’s El Niño will play out here.

So as you gear up for an El Niño winter, ask us your questions and we’ll do our best to get answers in the months ahead.

The company behind the Garden Grove hazardous waste scare earlier this year is planning to resume full operations in late September, subject to an independently monitored, court-approved safety plan.

GKN Aerospace employs 500 people at its Garden Grove facility.

What happened?

GKN Aerospace said in a news release that it had permanently decommissioned the tank that set off the hazmat scare in May and forced some 50,000 nearby residents to evacuate.

Removal of the tank is pending review and approval from state regulatory agencies, according to an emailed response from Salma Elshakre, a spokesperson for the Orange County Health Care Agency, which is overseeing the cleanup.

All of the toxic chemical, methyl methacrylate (also known as MMA), has been removed from nearby tanks as well, Elshakre said.

What about the compensation fund?

This week, the company also announced a forthcoming $100 million compensation fund for affected residents and businesses. GKN expects to release details on how to apply in the coming months.

What's next?

At least 39 lawsuits have been filed against the company in conjunction with the hazmat incident, according to a GKN webpage set up to track the fallout. The company pledged to explain the legal effect of participating in the compensation fund before it is launched.

What's the community reaction?

Garden Grove Mayor Stephanie Klopfenstein said in a statement that the city “welcome[s] this progress and will continue to expect GKN to address the broader effects on our community.”

A coalition of community groups called GKN Out of Garden Grove Coalition wants the city to shut down the GKN plant completely. The coalition plans to release a report documenting the company’s alleged history of hazardous waste failures at a news conference Tuesday at 5:30 p.m. at 11300 Stanford Ave. in Garden Grove.

WASHINGTON (AP) — The Trump administration is preparing to revoke the business and tourism visas of up to 200,000 foreigners who have applied for or are currently seeking asylum status in the United States. If it happens, the move would be the largest single mass revocation of visas in U.S. history and would likely face legal challenges.

Unless challenged or revised, the State Department is expected to announce in the coming weeks the revocation of so-called B1 and B2 visas issued between 2016 and 2026 whose holders have sought asylum or are now seeking asylum, according to State Department documents obtained by The Associated Press and two U.S. officials. The action will be taken in coordination with the Department of Homeland Security.

“We are coordinating with DHS to identify and revoke the nonimmigrant visas of foreigners who have come to the United States claiming to be short-term visitors, but then file for asylum to stay here permanently,” said State Department spokesman Tommy Pigott.

He declined to comment on the number of visas that might be revoked, saying “as the process will be ongoing, the number of revocations remains dynamic and will be done on a rolling basis.”

The revocations would not necessarily result in their immediate deportation, the officials said. Most of those with asylum cases currently pending would be recategorized but would lose their status as business or tourism travelers, according to the officials, who spoke on condition of anonymity because the revocations are not final yet.

Since President Donald Trump took office for his second term last year, his administration has steadily ramped up restrictions on visa applicants — demanding more information about their social media histories, requiring the posting of expensive bonds for the processing of visas, and outright banning the issuance of visas to citizens of certain countries.

In a social media post on Monday, Deputy Secretary of State Christopher Landau called out people who he said try to use tourist and business visas to get into the United States and then apply for asylum.

“People in the US and all over the world are fed up with bogus asylum claims,” Landau wrote on X. “Asylum isn’t supposed to be a loophole to circumvent immigration law.” Landau cited the case of a Colombian citizen who came to the U.S. in 2015 on a tourist visa and then applied for asylum.

B1 visas are generally issued for business trips and B2 visas are generally issued for tourism, family visits or medical care. It was not immediately clear from the documents or the officials how many of these visa holders are seeking or have sought asylum in the United States and would be affected by the revocations.

Current applicants for B1 and B2 visas are asked to affirm that they will not apply for asylum in the United States and prove that they intend to return to their home countries.

In the past 18 months, the State Department has revoked about 175,000 visas for people who have been convicted or accused of crimes ranging from drunken driving to rape and robbery, as well as for people who have spoken out publicly against U.S. policies, particularly in the Middle East.

The administration has also moved to crack down on so-called birth tourism, a practice the administration claims is used by foreign pregnant women to come to the United States to give birth so that their child will benefit from birthright citizenship. Trump has tried several times to end birthright citizenship, but those challenges have been rejected by courts, including the Supreme Court.

The State Department documents obtained by the AP suggest screening of current B1 and B2 visa holders began after the State Department received information about asylum requests from the U.S. Citizenship and Immigration Services.
