An electric arc sent molten metal into the dry vegetation below.  It ignited.<\/p>\n<p>Five minutes later, a PG&amp;E employee spotted the fire while driving on a nearby highway and reported it. Within two hours of the sighting, the town of Paradise, seven miles away, sent its first evacuation order, but it was already too late. Within two minutes,  flames were reported at the town\u2019s edge. Landing embers quickly ignited dozens of spot fires in town. With only four major roads out of town,  the streets quickly gridlocked. Paradise burned.<\/p>\n<p> Sixty-four people died in Paradise during the agonizing seven-hour evacuation. Six of them were found in or next to their cars as they tried to evacuate. <\/p>\n<p>Marc Levine, a state legislator at the time, listened over radio to the horrific scenes of people, stuck in traffic, abandoning their cars to flee on foot.<\/p>\n<p>\u201cIt made me think of the people falling from the World Trade Centers on 9\/11,\u201d he said. \u201cThey were going to be incinerated or they were going to jump. \u2026 They knew they would die either way.\u201d<\/p>\n<p>So, Levine <a class=\"link\" href=\"https:\/\/leginfo.legislature.ca.gov\/faces\/billNavClient.xhtml?bill_id=201920200AB747\" target=\"_blank\" rel=\"noopener\">wrote legislation<\/a> requiring California cities and counties to analyze whether their roads could support a quick evacuation during emergencies such as fires, floods and tsunamis. Assembly Bill 747 passed in 2019. Yet, to date, the city of Los Angeles has failed to publicly report such an analysis, while fire safety advocates say L.A. County\u2019s evacuation analysis fails to meet the law\u2019s requirements.<\/p>\n<p>The Times reached out to nearly a dozen city, county and state agencies involved with evacuation planning. All either did not respond to requests for comment, could not to point to an evacuation analysis in line with the state\u2019s guidelines for AB 747 or indicated the responsibility for doing the work lie with other agencies.<\/p>\n<p>\u201cThe fact that local government leaders would not do as much as they can to protect human life and safety is just shocking to me,\u201d Levine said.<\/p>\n<p>In January, the streets of Pacific Palisades mirrored the scene that distressed Levine in 2018. Traffic was at a standstill on Sunset Boulevard and Palisades Drive \u2014 two of the only routes out of the burning landscape. When a spot fire exploded next to the route, police ran down the street, shouting at evacuees to run for their lives.<\/p>\n<p>Every year, dozens of evacuations are ordered in California, organized and completed without any casualties \u2014 or even a news story. In these cases, public safety officials have all the lead time that they need to organize a safe and orderly evacuation before a fire reaches a community.<\/p>\n<p>But it\u2019s the much more dire evacuation scenarios \u2014 when the lead time is shorter than the time it takes to evacuate, like in the Palisades \u2014 where emergency planning is both most important and often ignored.<\/p>\n<p>\u201cThere\u2019s no incentive to ever present an evacuation plan that isn\u2019t very positive,\u201d said Thomas Cova, a professor at the University of Utah who <a class=\"link\" href=\"https:\/\/doi.org\/10.1061\/(ASCE)NH.1527-6996.0000474\" target=\"_blank\" rel=\"noopener\">studies wildfire evacuation analysis.<\/a> \u201cWhy would an emergency planner \u2014 say some young upstart in an emergency operation center \u2014 ever want to present a plan to their colleagues that involves some people burning?\u201d <\/p>\n<p>The chaos of these worst-case scenario evacuations often look nothing like the orderly phased evacuations cities often focus on. Unlike in \u201cblue sky\u201d evacuations, smoke can hinder visibility and cause crashes. Often whole towns must leave at once. Power outages can prevent public safety officials from communicating with residents.<\/p>\n<p>It\u2019s why Marylee Guinon \u2014 president of the State Alliance for Firesafe Road Regulations, an advocacy group aimed at protecting and expanding the state\u2019s community fire safety requirements \u2014 suspects AB 747 is facing pushback from local governments. \u201cThey don\u2019t want data that would tell them that it\u2019s going to be a nine-hour evacuation,\u201d she said. <\/p>\n<p>All the while, the risk of fast-moving fires is growing.<\/p>\n<p>In a <a class=\"link\" href=\"https:\/\/www.science.org\/doi\/10.1126\/science.adk5737\" target=\"_blank\" rel=\"noopener\">2024 study<\/a>, researchers from the University of Colorado in Boulder analyzed more than 60,000 fires documented by NASA satellites in the first two decades of the 21st century. By 2020, fires in California were growing, on average, four times faster than they were in 2001. <\/p>\n<p>L.A.\u2019s missing evacuation analyses<\/p>\n<p>AB 747 requires local governments to include their evacuation analyses in the safety element of their general plan \u2014 the long-term blueprint for future development of a city or county.<\/p>\n<p>The city of L.A.\u2019s current safety element provides no such analysis. Instead, it simply lists evacuation planning as \u201congoing.\u201d<\/p>\n<p>In a statement to The Times, the city\u2019s Planning Department, responsible for writing and revising the general plan, said details of evacuation routes are not made publicly available since \u201clarge urban cities such as the City of Los Angeles are high profile targets for terrorist attacks.\u201d<\/p>\n<p>The city did not immediately clarify what legal authority it has to keep the analysis private  as California law generally requires safety elements to be public.<\/p>\n<p>\u201cIt is a mystery how hiding evacuation route capacity and viability can save lives when community members are fleeing a natural disaster,\u201d Levine said in an email  to The Times. \u201cIt is a dubious claim that terrorists could possibly be well positioned to take advantage of such a catastrophic situation.\u201d<\/p>\n<p>Meanwhile, the county said it complied through an analysis it included in its <a class=\"link\" href=\"https:\/\/planning.lacounty.gov\/wp-content\/uploads\/2025\/04\/12.1_gp_final-general-plan-ch12_updated_2025.pdf\" target=\"_blank\" rel=\"noopener\">2025 safety element<\/a>. However, fire safety advocates criticized the county\u2019s analysis as simplistic and failing to adequately determine whether quick and safe evacuations are feasible.<\/p>\n<p>The Governor\u2019s Office of Land Use and Climate Innovation, which provides guidance on state planning laws, recommended that local governments use traffic software to simulate different evacuations to estimate how long they might take. Instead, the county grabbed a list of all roads in unincorporated areas within its borders and listed them as \u201cevacuation routes\u201d so long as they were paved, public and not a dead end.<\/p>\n<p>The intent of the law is \u201cnot \u2018just list the roads you have,\u2019\u201d Levine said. \u201cSo I\u2019m super disappointed that L.A. County is dismissive in this way. You would expect, particularly post this year\u2019s fires, Palisades and Eaton, they would take this far more seriously.\u201d<\/p>\n<p>When pressed on their deviations from the state\u2019s guidance, both the city and county planning departments passed the buck to the California Department of Forestry and Fire Protection, which indicated in assessments that the two departments\u2019 safety elements were compliant.<\/p>\n<p>Cal Fire, however, said that its assessments were nonbinding and that complying with the law falls on the city and county.<\/p>\n<p>Yet, none of the local or state agencies directly responded to an inquiry from The Times asking them to explain the discrepancy between the guidance and the safety elements.<\/p>\n<p> The city and county both have detailed evacuation plans that coordinate how public safety officials in the emergency operations, police and fire departments would orchestrate a mass exodus. However, the analysis of roadway networks to estimate how long those evacuations \u2014 even if perfectly orchestrated \u2014 may take, is different.<\/p>\n<p>\u201cHistorically, fire agencies put forth evacuation plans that are operationally driven,\u201d said retired fire Battalion Chief Doug Flaherty. \u201cThey talk about communications. They talk about unified command. \u2026 What is missing is an actual detailed, road-by-roadway capacity analysis of the time that it\u2019s going to take for people to safely evacuate the area.\u201d<\/p>\n<p>For Guinon, the lack of follow-through from cities and counties <a class=\"link\" href=\"https:\/\/www.mercurynews.com\/2025\/03\/02\/santa-clara-county-wildfire-evacuations-preparations\/\" target=\"_blank\" rel=\"noopener\">across the state<\/a> is indicative of a common trend in wildfire legislation.<\/p>\n<p>\u201cVirtually every piece of legislation that I dig into, I find out it was the result of a tragic catastrophe,\u201d she said. \u201cThis legislation comes out with really, really clear intent over and over, and then it gets forgotten.\u201d<\/p>\n<p>Understanding the problem is half the solution<\/p>\n<p>Despite the complexity of simulating cars on a computerized network of roads to understand evacuation times, the scientific prowess exists \u2014 and the software to do it is widely accessible.<\/p>\n<p>When Flaherty, a Tahoe Basin resident, became frustrated with his area\u2019s lack of movement on the issue, he commissioned an evacuation study through his nonprofit, <a class=\"link\" href=\"https:\/\/tahoecleanair.org\" target=\"_blank\" rel=\"noopener\">TahoeCleanAir.org<\/a>.<\/p>\n<p>The retired fire battalion chief, with 50 years of emergency response planning experience under his belt, partnered with Leo Zlimen,  fresh out of UC Berkeley and co-founder of the <a class=\"link\" href=\"https:\/\/www.ladris.com\/\" target=\"_blank\" rel=\"noopener\">emergency management software startup Ladris.<\/a><\/p>\n<p>\u201cWe fell into this wildfire space because everywhere we looked, people were [asking] \u2018draw a circle on the map and tell me how long it takes to get those people out,\u2019\u201d Zlimen said. \u201cAnd it turns out, that\u2019s actually a really complicated problem.\u201d<\/p>\n<p>Ladris\u2019 software simulates realistic fire evacuations. It starts by taking a map of roads in a community and plopping little purple dots at virtually every home. Each one represents a vehicle. <\/p>\n<p>A fire starts on the map. It spreads. The purple dots get orders to flee, and the evacuation starts.<\/p>\n<p>The computer can play out a multihour evacuation in mere seconds, and it can account for an excruciating amount of detail. A roadblock, representing a falling tree or car crash, can stop purple dots from using a portion of the road. Some purple dots, not realizing how dire the situation is, wait an extra few minutes \u2014 or hours \u2014 to evacuate. The dots even wait their turn at stop signs, crosswalks and traffic lights. <\/p>\n<p>            <img class=\"image\" alt=\"A screen showing a map of an area marked in pink and purple, with thin green lines\"   width=\"2000\" height=\"1405\" src=\"https:\/\/www.europesays.com\/us\/wp-content\/uploads\/2025\/07\/1753438451_239_\" decoding=\"async\" loading=\"lazy\"\/>         <\/p>\n<p>Ladris\u2019 software simulates realistic fire evacuations. It starts by taking a map of roads in a community and plopping little purple dots at virtually every home. Each one represents a vehicle.<\/p>\n<p>(Ladris)<\/p>\n<p>Ladris\u2019 program almost looks like a video game. Officials can test evacuation scenarios far in advance or in real time during an emergency. The company is also working to use artificial intelligence to help quickly configure scenarios so users can almost literally \u201cdraw a circle on the map\u201d and get an evacuation time.<\/p>\n<p>Flaherty said his detailed Tahoe Basin study, a comprehensive analysis based on Ladris\u2019 simulations, had a price tag just shy of $100,000 \u2014 roughly equivalent to the cost of installing one traffic light in town.<\/p>\n<p>\u201cIn the scheme of things, it\u2019s very cost effective and reasonably priced,\u201d he said. <\/p>\n<p>Another <a class=\"link\" href=\"https:\/\/fleet.vmasc.odu.edu\/\" target=\"_blank\" rel=\"noopener\">piece of software from Old Dominion University<\/a> \u2014 simpler than Ladris\u2019 \u2014 is available to the public for free. It takes less than half an hour to set up a simulation in the program, called FLEET (for \u201cFast Local Emergency Evacuation Times\u201d).<\/p>\n<p>Consequently, it\u2019s been used not only by local governments making fire evacuation plans, but also by Scouting America troops interested in flood hazards and event planners wondering how bad the postgame traffic may be.<\/p>\n<p>Among those using FLEET simulations for evacuation planning: the town of Paradise.<\/p>\n<p>How to shorten a five-hour evacuation<\/p>\n<p>After the Camp fire, Paradise became an inadvertent experiment in how towns can better prepare for evacuations. After the disaster,  it won a $199-million federal grant for infrastructure projects designed to rebuild Paradise into a more fire-safe town. Before the fire, the town\u2019s entire yearly budget was around $12 million.<\/p>\n<p>After the Camp fire, Paradise hired a traffic consulting firm that used FLEET. It found an evacuation would take over five hours under perfect conditions while utilizing all traffic lanes. It then used the modeling to understand what could be done to alter traffic flow to  reduce that time.<\/p>\n<p>For Paradise \u2014 as is the case for many towns \u2014 a big problem is traffic bottlenecks: To evacuate, virtually the entire town has to use one of four main roads.<\/p>\n<p>The seemingly most straight-forward solution? Build more roads. However, these projects get complicated fast, said Marc Mattox, Paradise\u2019s public works director and town engineer.<\/p>\n<p>Often the roads that a municipality needs to improve evacuation would have to go through private property \u2014 a nonstarter for residents in the proposed path. <\/p>\n<p>Or, it\u2019s simply too costly. Although Paradise has received funds  to widen two evacuation routes and connect three dead ends with the rest of town, a new evacuation route out of town would be prohibitively expensive. Mattox estimated such a route, navigating Paradise\u2019s steep ridges and canyons, would cost in excess of half a billion dollars.<\/p>\n<p>So, Paradise has also invested in a much cheaper, yet still effective tool to speed up evacuations: clear communication.<\/p>\n<p>Paradise installed signs all over town that proclaim when residents enter and exit different evacuation zones. The town is also looking into using a different color sign for private or dead-end roads that warn drivers to avoid them, as well as digital signs above key roadways that can display real-time evacuation information.<\/p>\n<p>In Southern California, Malibu \u2014 which completed an evacuation analysis after it suffered the Woolsey fire the same day as the Camp fire \u2014 has similar plans.<\/p>\n<p>Malibu is adding reflective markers to roadways to reduce the chances of crashes amid thick smoke. For neighborhoods with few evacuation routes and individuals with limited mobility, the city encourages evacuating whenever the National Weather Service warns of dangerous fire weather \u2014 well before a possible ignition.<\/p>\n<p>Los Angeles is much bigger than Malibu and Paradise \u2014 L.A. has a population of 3.9 million; Paradise\u2019s is just over 9,100. But evacuation experts said it\u2019s no excuse for letting California\u2019s rural towns take the lead on evacuation planning.<\/p>\n<p> Asked whether the sprawling labyrinth of L.A. roads would make doing these analyses more difficult, Zlimen smiled.<\/p>\n<p>\u201cNot really \u2014 no,\u201d he said, noting Ladris has completed analyses in the San Francisco Bay Area. \u201cIt\u2019s totally possible.\u201d<\/p>\n<p>Guinon hopes the results of evacuation analyses can also help \u2014 or force \u2014 cities to make more responsible residential development plans in the first place.<\/p>\n<p>\u201cIt\u2019s not rocket science,\u201d she said. \u201cLet\u2019s just take on protection of our existing communities and let the chips fall where they may with new development: If it\u2019s unsafe, don\u2019t build it.\u201d<\/p>\n","protected":false},"excerpt":{"rendered":"Just before sunrise on Nov. 8, 2018, a power line fell from a wind-worn Pacific Gas &amp; Electric&hellip;\n","protected":false},"author":3,"featured_media":91106,"comment_status":"","ping_status":"","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[5123],"tags":[529,1582,276,2451,3059,3537,60547,60546,5025,2961,224,5337,60542,60545,60543,60544,50201,6620,637,52582],"class_list":{"0":"post-91105","1":"post","2":"type-post","3":"status-publish","4":"format-standard","5":"has-post-thumbnail","7":"category-los-angeles","8":"tag-analysis","9":"tag-ca","10":"tag-california","11":"tag-city","12":"tag-county","13":"tag-evacuation","14":"tag-evacuation-analysis","15":"tag-evacuation-plan","16":"tag-fire","17":"tag-la","18":"tag-los-angeles","19":"tag-losangeles","20":"tag-major-road","21":"tag-marc-levine","22":"tag-safety-element","23":"tag-sixty-four-people","24":"tag-state-agency","25":"tag-time","26":"tag-times","27":"tag-town"},"share_on_mastodon":{"url":"https:\/\/pubeurope.com\/@us\/114913350025009534","error":""},"_links":{"self":[{"href":"https:\/\/www.europesays.com\/us\/wp-json\/wp\/v2\/posts\/91105","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.europesays.com\/us\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.europesays.com\/us\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.europesays.com\/us\/wp-json\/wp\/v2\/users\/3"}],"replies":[{"embeddable":true,"href":"https:\/\/www.europesays.com\/us\/wp-json\/wp\/v2\/comments?post=91105"}],"version-history":[{"count":0,"href":"https:\/\/www.europesays.com\/us\/wp-json\/wp\/v2\/posts\/91105\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.europesays.com\/us\/wp-json\/wp\/v2\/media\/91106"}],"wp:attachment":[{"href":"https:\/\/www.europesays.com\/us\/wp-json\/wp\/v2\/media?parent=91105"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.europesays.com\/us\/wp-json\/wp\/v2\/categories?post=91105"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.europesays.com\/us\/wp-json\/wp\/v2\/tags?post=91105"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
