The Brief

Should you be allowed to have trees or potted plants next to your home in a fire-prone area? That’s the kind of question the California Board of Forestry and Fire Protection is figuring out right now.

The devastation of the January wildfires led to a renewed push for mandated ember-resistant zones around certain properties, which were first approved under AB 3074 in 2020. The incoming regulations will also affect existing properties down the line.

The board’s Zone Zero advisory committee started holding public workshops last week where residents can give input. Here’s what you should know to get involved.

What the regulations could cover

Setting up a “Zone Zero” has been a recommended practice for home fire prevention for a while, but the regulations that would make it a requirement aren’t in place yet.

The idea is that by creating a 5-foot area of “defensible space,” homes will have a better chance of not burning because embers are less likely to catch something on fire. According to the Insurance Institute for Business and Home Safety, properties with this clearance survive wildfires at nearly double the rate of ones without it.

A working group has been ironing out the details of what would be allowed to stay in that 5-foot zone and what wouldn’t. So far, here’s what they’re recommending to allow:

• Rocks, pavers, statuary, foundations and cement.
• Mature trees (as long as branches are 10 feet above the roof and chimney).
• Parallel fences (for existing properties).
• Irrigated and mowed grass (up to 3 inches).
• Irrigated, non-woody plants (groundcover and plants would have height restrictions).
• Potted plants up to 2 feet in height in noncombustible pots (e.g. ceramic, metal, and cement).

And here’s what may not be allowed:

• Synthetic lawns.
• Combustible decorative structures (e.g. trellis, privacy walls, and more).
• Combustible fences or gates.
• Some storage structures.
• Some landscape materials (e.g. wood mulch, wood or petroleum-based boards usually used in garden beds).
• Potted plants (including wine barrels, wood pots, and plastic).

Once the Zone Zero rules are finalized later this year, it will apply to all land under the state’s responsibility, as well as locally-controlled areas identified as having a very high fire risk. Property owners for existing buildings will have three years to comply with the changes once implemented.

You can check the state map here to see if your property is in the responsibility area. The map for fire hazard zones in Los Angeles County is currently being revised and should be released here under Phase 4 of the update by March 24.

How you can share feedback

The committee is expected to have a draft of the regulations by March 21. And your next chance to get involved in the meetings will be on April 7 and May 16.

The meetings are held in person at the California Natural Resources agency in Sacramento. But don’t worry — there is a virtual option too.

Officials recommend you subscribe to the board’s email list to receive the meeting information when it comes out, and RSVP if you’re going to join. You can also send comments to PublicComments@bof.ca.gov.

A crew of four moon-bound astronauts will remain on the ground for at least a month after NASA delayed the launch of the Artemis II mission. During critical pre-launch testing Monday, mission managers uncovered a number of issues that prevented the completion of the test.

NASA is now planning a March launch date for the four astronauts — three from the U.S. and one from Canada — on a ten-day mission to circle the moon and return to Earth, traveling farther than any humans have ventured into deep space.

Issues leading to that delay began about an hour into Monday's test, known as the wet dress rehearsal. As the team began fueling the rocket at the Kennedy Space Center in Florida, sensors picked up a hydrogen leak. Super-chilled hydrogen is used as the fuel for the massive Space Launch System (SLS) rocket.

Hydrogen is an efficient propellant for rockets — but its molecules are so tiny and light they can escape even the tightest of seals. Launch director Charlie Blackwell-Thompson said they had troubleshooted the initial leak, but when they began to pressurize the tank, another leak surfaced.

"And so as we began that pressurization, we did see that the leak within the cavity came up pretty quick," said Blackwell-Thompson.

Hydrogen leaks plagued testing of NASA's Artemis I mission in 2022. Blackwell-Thompson said lessons learned from that uncrewed flight were utilized for Artemis II, but there's more investigation is needed.

The wet dress rehearsal uncovered other issues — including a problem with the Orion capsule, which will carry the crew to the moon. While no one was on board Monday, teams practiced preparing the spacecraft for its passengers. A valve that pressurizes the vehicle required additional attention and took more time to close the hatch than anticipated.

Teams also uncovered issues with cameras due to cold weather and audio dropouts across communication channels. "As always, safety remains our top priority, for our astronauts, our workforce, our systems and the public," said NASA administrator Jared Isaacman in a post on X, and that NASA will only launch when the agency is ready.

Work now begins to fix the issues. NASA will require another wet dress rehearsal before giving the "GO" to put astronauts on board. "All in all, a very successful day for us on many fronts," said Blackwell-Thompson. "Then, on many others, we got some work we've got to go do."

The earliest launch window for another attempt is March 6. NASA has additional launch opportunities on March 7, 8, 9 and 11.

The crew of NASA astronauts Reid Wiseman, Victor Glover, Christina Koch, and Canadian Space Agency astronaut Jeremy Hansen were released from quarantine and will remain in Houston, Texas. They'll re-enter quarantine about 14 days ahead of the next launch attempt and make the trip to the Kennedy Space Center six days before liftoff.

Artemis II is testing key systems of the Orion spacecraft, like its maneuverability and life support systems, ahead of the planned Artemis III mission that will take humans to the lunar surface. The Artemis II will mark the first time humans have returned to the moon since the final Apollo lunar mission in 1972.

A trial got underway Tuesday in a case alleging that Huntington Beach illegally dilutes the power of Latino voters with its at-large election system.

Cities across Orange County and elsewhere in California have faced similar challenges over the past decade. Most have settled out of court by adopting by-district elections, where voters only vote on a city council representative from their area, rather than requiring candidates to run citywide. A notable exception is Santa Monica — the city has been fighting a challenge to its at-large election system in court for nearly 10 years.

Now, Huntington Beach is following suit.

The case was brought by the nonprofit group Southwest Voter Registration Education Project and Victor Valladares, a Huntington Beach resident and Democratic Party activist. It’s being heard by Orange County Superior Court Judge Craig L. Griffin.

The argument against at-large city elections

The plaintiffs allege Latino voters can’t elect a candidate of their choice under the current system, in violation of the California Voting Rights Act. This alleged dilution of Latino voting power, they say, leads to poor representation and negative consequences for the city’s majority-Latino Oak View neighborhood.

“Their needs get ignored,” Kevin Shenkman, the plaintiffs’ lawyer, said during his opening statement Tuesday. “It is a natural result of the at-large election system.”

Latinos make up about 20% of the population in Huntington Beach. Under a draft map of electoral districts drawn up by demographer David Ely, a witness for the plaintiffs, the district that includes the Oak View neighborhood would be 40% Latino. Plaintiffs argued this would give residents more power to elect a city councilmember who represents their interests.

The city’s defense of at-large elections

In their opening argument, lawyers representing Huntington Beach argued that Latinos in Huntington Beach are spread across the city and politically diverse.

The city’s lawyers also argued that recent elections of Latino city council members, including MMA star Tito Ortiz in 2020 and Gracey Van Der Mark in 2022, prove the city’s current at-large election system doesn’t impede Latino residents’ ability to participate in the local political process.

“The system works, it’s not broken, and the evidence will show that at trial,” said Anthony Taylor, one of the attorneys representing Huntington Beach.

The trial is expected to last into next week.

In a week when temperatures are 20 degrees above average in parts of Southern California, the L.A. County Board of Supervisors unanimously approved the county’s first heat action plan.

The plan lays out strategies to achieve three goals in coming decades: cooler outdoor spaces, cooler indoor spaces and better public education about the dangers of heat.

The blueprint, approved Tuesday, comes as L.A. County and the world are experiencing longer, hotter and deadlier heat waves as a result of pollution trapped in the Earth’s atmosphere. It’s one of the only such plans in the region dedicated to extreme heat.

Why it matters

Already, heat is responsible for the deaths of more than 200 people each year in L.A. County, as well as thousands of emergency room visits. Since the 1980s, summer temperatures, particularly in the valleys and inland areas, have risen on average 3 degrees, with expected increases as high as 8 degrees on average in certain areas, such as the Antelope Valley, according to the plan.

Unless global pollution is dramatically reduced, by 2050, average temperatures in L.A. County are expected to rise nearly 4 degrees. The valleys and inland regions will see the highest heat: The San Gabriel Valley could see the number of extreme heat days above 95 degrees go from 32 a year to 74. But coastal areas won’t be spared: Long Beach could see extreme heat days quadruple, from just four days on average above 95 degrees to 16, according to local projections.

Nights are getting hotter even faster, disrupting sleep and impacting health in ways we don’t yet understand — 41% of L.A. County residents who responded to a survey for the heat action plan reported trouble sleeping on very hot nights.

“We needed to develop an all-of-government framework for dealing with rising temperatures,” said Ali Frazzini, policy director with the county’s sustainability office.

Nights are heating up faster than days as a result of climate change, affecting our sleep and health in ways we don't yet fully understand.

An invisible threat

The plan includes goals for strategies such as replacing blacktop at schools, installing shade structures, and enforcing renter protections for safe indoor temperatures.

“There wasn't the same level of centralization and systems for responding to and adapting to heat as we see with some of our other hazards,” Frazzini said.

Unlike earthquakes or wildfires, heat is something of an invisible threat, she said — it’s ubiquitous, though experienced in unequal ways, and it doesn’t cause extensive property damage. It’s not confined to certain regions.

Despite being the leading weather-related cause of death in the U.S. and here in Southern California, heat is not officially recognized as a disaster at a state or federal level, which limits funding support for public health interventions. The county hopes the plan will unify its efforts across departments and draw more state and federal funding to protect public health.

Strategies to live in a hotter LA 

The plan builds on four years of work since 2021, when the county released its first climate vulnerability assessment.

“That assessment told us where our problems were and what they were, and this plan now tells us how to address them,” said Rita Kampalath, the county’s chief sustainability officer.

Most of the strategies highlighted in the plan are in progress, though many have faced serious delays. For example, one goal includes adding shade structures to all L.A. County bus stops by 2045 — county leaders have attempted to do this for decades, and progress has been extremely slow. Other goals include greening schools and planting trees in neighborhoods with the least shade. Efforts to green schools have faced stops and starts due to funding challenges and lack of planning, though there is progress. And planting trees where they’re most needed has proved to be a lot more difficult than it may seem.

Despite the challenges of implementing the ideas, V. Kelly Turner, a heat researcher at UCLA who served on an advisory group for the plan, said "one thing the L.A. County heat action plan gets fundamentally right is that it centers people and the everyday ways that heat becomes a disruptor to daily life."

Another unique aspect of the plan, she said, is that it used shade data, not only temperature data, to inform its strategies.

"Few cities around the world are using shade maps to systematically inform heat resilience planning," she said. "So, in that respect, the county's heat action plan is truly a leader."

Below are some selected facts and figures from the plan.

Goals for 2045:

• Install functional shade structures at 100% of L.A. County bus stops. 
• Achieve 20% tree canopy in unincorporated areas. 
• Replace 1,600 acres of pavement at schools and public spaces.
• Enforce new rules that require landlords to keep units below 82 degrees.
• Reduce energy burden for low-income households to 4% of monthly budget.
• Create 30% more county cooling centers for 234 regionwide by 2045, as well as support solar and battery installation at trusted indoor community spaces.
