Four years before the fires of Pallisard and Eton destroyed La, Irvine was supported by its own flame.
As Santa Ana roared the area at 80 mph, the summer of bone-door drizzled out of its dry state and ignited. On the morning of October 26th, 2020, the Silverado fire erupted.
Firefighters deployed. The city has launched an emergency plan. Orchard Hills residents – masterplan communities sitting on a rapidly growing fire path, spanning wild urban interfaces – didn’t know if they would see the house again.
Firefighters from the Orange County Fire Department are working to protect a home in Irvine’s Orchard Hills area during the October 2020 Silverado Fire.
All of them will. The flames licked in the neighbours’ suburbs and toasted several leaves around, but did not damage the single residence of the community.
The shootout was a clear victory. The product of the meticulous planning of the neighborhood, the home design, the painstaking plan set by the city.
As LA appears to be bolstering against future fires, Orchard Hills could serve as a roadmap to get there.
Of course, the comparison is not accurate. Irvine is a new city where modern homes were built using lessons learned from dozens of deadly fires over the years. Palisades in the Pacific are communities of Century homes, planted with trees and Century homes, with narrow, sometimes winding roads filled with vegetation.
But seeing climate change burning over and over again in Southern California, experts say it’s worth extracting and mining success stories.
It can be argued that the fire resistance of Orchard Hills began a century ago when Irvine Valencia growers planted avocado orchards on the hill above the community. The orchard has since grown into one of the nation’s largest avocado producers, with around 100,000 trees over 800 acres.
It offers much more to the neighborhood than guacamole.
“The orchards have built-in irrigation systems, so when a fire occurs, the landscape is already deserted,” said Sean Dolan, the fire chief with the Orange County Fire Department.
Doran, who fought the Silverado fire, retarded his team back when developer Irvine broke the ground in 2014 thanks to a decade-long partnership between Orchard Hills and fire officials. He said he raised it.
Irvine requires building plans to pass through fire authorities as a conditional license to the developer.
“It’s inherent in the process,” Doran said. “If you’re a developer, you’re walking down our door at some point.”
The partnership between developers and fire agencies has brought strict rules about what can and cannot be built, and many home buyers are grateful for the regulations.
Ron Nestle, an Orchard Hills resident and senior principal of William Hizmalhalch’s architect, noticed a small coil of smoke while walking his dog on the morning of Silverado Fire. An hour later he evacuated the house.
Ronnestle and his dog, Enzo, are enjoying his backyard this month at Orchard Hills in Irvine.
He’s gone for three days. When he returned there was no damage.
“This is evidence of how this place was planned,” he said.
When Nestor moved to Orchard Hills five months ago, the neighbouring fire plans that Irvine Co. advertised on its website were the factors behind the move. Those who researched wind patterns, terrain and fire history.
Orchard Hills is designed with many levels of defense due to neighborhood fires. The open land, yards, and the house itself surrounding the neighborhood.
It starts with the fuel correction zone. Open spaces around the community can be changed to reduce fire risk by replacing flammable vegetation with fire-resistant shrubs. The Orchard Hills zone is filled with spiny pear cactus, Japanese honeysuckle and Formo Safia Thorn.
Orange County Fire Guidelines require three different layers of fuel change zones, with different construction requirements and shrub removal rates typically extending up to 200 feet from the perimeter. If the developer wants to tighten that zone to 100 feet, they have to make up for it in other ways, such as building exterior walls around the neighborhood or adding extra fortress to the house at the edge of the neighborhood. yeah. ‘Fires fire and brings the fire inside.
The open spaces around Orchard Hills are filled with spiny pear cactus, Japanese honeysuckle and Formo Safia Thorn.
“Not everything is specific, so you can give some room in one area and tighten another,” Dolan said. “We are here to support the community where the fire has occurred. Anything that makes it happen is a success for both parties.”
In the case of Orchard Hills, fire officials work with farmers to fine-tune the spacing of avocado trees to reduce the amount of trees per acre, clear orchard brushes and sages to burn the 170-foot fuel correction zone. Restricted the substance.
The next level of defense is where open spaces meet the exterior edges of the home.
Irvine has built a six-foot wall around an enclave in the nearby northern part of the country – Santa Ana’s wind fire is likely to hit first – protecting the most vulnerable properties from radiation heat and flying low Eliminate embers of development.
It strengthened the home along its edge, exceeding the required fire hardening standards for the rest of the neighborhood. These sections require external doors for shooting ratings and strict guidelines for outdoor features such as decks and trellis.
The final line of defense is nearby.
No wooden covered craftsmen can be found in Orchard Hills. In fact, there is no exposed wood at all. If so, it is treated as a fire return agent. The masonry walls and vinyl fences are separated, and some wooden gates are separated by metal columns, so the fire cannot be spread out in the house, Nestor said.

The Orchard Hills home is built with two factors in mind: radiant heat and the invasion of Ember. Radiant heat is the heat projected by fire. If the exterior of the house is made of flammable materials, the house can be heated until ignition. Therefore, the house is mostly Mediterranean, wrapped in stucco and fiber cement (non-flammable material), with some splashes of stone and brick thrown in.
Another factor is the Ember Intrusion when the Ember enters the house through the opening and ignites from inside. Orchard Hills homes are equipped with stronger glass than single-pane windows, which tend to break fires. The roof vents have mesh filters that block embers. The roof is equipped with concrete or clay tiles. The concrete tiles will flatten and stop embers from entering. With barrel clay tiles, the openings at the bottom of each row are packed with bird stops.
HOA guidelines are strict and solid, dictating acceptable plant types and allowing trees to be planted. Nestor said he appreciated the precautions.
“When the neighborhood was tested, it was endured and people are sure their home will survive,” Nestor said. “Everything went exactly as planned.”
Doran said that in combination with the wall, the Fuel Correction Zone helped stop the Silverado fire with that truck.
“I saw the fire burn out to the edge of the wall before dying,” he said.
Fire after a fire indicates that one of the most important aspects of an emergency is the road. In the 2018 camp fire, eight of the 84 people who died were stuck in traffic jams as the flames roared over them.
Most of Irvine is sailed by smooth, wide roads, making it much easier for people to evacuate and firefighters to fall into fire. In Orchard Hills, a 7-foot-wide pass runs behind the property, allowing firefighters and vehicles to access the back of the house properly.
Bobby Simmons, Irvine’s Emergency Services Manager, will help coordinate the city’s strategy.
In 2019, a year before the Silverado Fire, which resulted in the Camp and Woolsey fires, Simmons set up an initiative of 25 to help create a comprehensive wildfire plan. That role.
Firefighters will protect the Orchard Hills home in 2020. Silverado Fire licked in the suburbs around Irvine, but it did not damage the community home.
Police stations will send patrols to certain intersections to assist with evacuation. Traffic Management Centers control the traffic lights remotely and avoid traffic jams by turning all lights green. Simmons said the Emergency Management Agency will mobilize the Emergency Business Center and activate emergency landing pages on the website, leading to a real-time evacuation map.
“We created a plan, challenged it and tested it so much that when Rubber came across the road on October 26th, we were structured processes for a chaotic event. provided,” Simmons said. “It all took into consideration, and it went smoothly.”
During the Silverado fire, the city evacuated 90,000 people in four hours from Northern Irvine communities, including Orchard Hills and Portra Springs.
Silverado fire is lit near the Orchard Hills home in 2020, so it spins the Sky Orange.
In the end, the Silverado fire was still a victim. There was no damage to Orchard Hills, but five structures were destroyed elsewhere, causing 11 people to be damaged and two firefighters seriously injured. And while traffic was quickly flowing out of the neighbourhood, the car was backed up for over a mile as the lights on the five highways were controlled by Caltrans instead of Irvine, and the car was backed up for over a mile and northeast.
There is always something to learn.
“Now we’re identifying lessons we’ve learned to prepare for the next lesson,” Simmons said.
