Their crews would clear dry brush from forests, create fuel breaks, and conduct prescribed burns. When wildfires eventually tested those treatments, oftentimes the flames moved slower, giving firefighters more time to battle the blaze.<\/p>\r\n<p style=\"font-weight: 400;\">But there was a problem. While firefighters and foresters saw the advantages on the ground, they couldn\u2019t consistently prove those outcomes to the legislators and policymakers in charge of critical funding.<\/p>\r\n<p style=\"font-weight: 400;\">Today, the California Department of Forestry and Fire Protection (CAL FIRE) uses a new data-driven system built with geographic information system (GIS) technology to track the real-time impact of fuel treatment activities.<\/p>\r\n\r\n<h3 style=\"font-weight: 400;\"><strong>Real-Time Proof and Quantifiable Outcomes<\/strong><\/h3>\r\n<p style=\"font-weight: 400;\">Frank Bigelow, deputy director for CAL FIRE\u2019s Community Wildfire Preparedness and Mitigation Division, is quick to admit the old way of proving fuel treatment effectiveness was cumbersome and often abandoned.<\/p>\r\n<p style=\"font-weight: 400;\">\u201cIt was done on paper, and it was arduous,\u201d said Bigelow, who oversees 22 programs, including those that deal with defensible space inspections and wildfire prevention grants. \u201cWe knew we were having positive outcomes, but being able to tell the story was where we were falling short.\u201d<\/p>\r\n<p style=\"font-weight: 400;\">That changed when CAL FIRE tied data from its disparate systems to one GIS map.<\/p>"},{"acf_fc_layout":"gallery","gallery_images":[768767,768766,768769]},{"acf_fc_layout":"content","content":"<p style=\"font-weight: 400;\">Now any time a fire starts, the incident reporting system drops a point on the map. The database automatically queries for mitigation treatments within a half mile of that location. Then the system generates a data collection survey to be used for an on-the-ground assessment.<\/p>\r\n<p style=\"font-weight: 400;\">\u201cWithin days, the results are live on a public dashboard,\u201d Bigelow said.<\/p>\r\n<p style=\"font-weight: 400;\"><a href=\"https:\/\/experience.arcgis.com\/experience\/91ab6b7f0b414d0ea06bf269a4632e15\/page\/Treatment-Reporting-Overview\">Results from the first year are eye-opening<\/a>. CAL FIRE assessed 81 areas that had fuel treatment and were then impacted by wildfire. They found 61 of those areas showed positive outcomes\u2014meaning the treatments either slowed the fire, stopped it from destroying property, improved firefighter access, or supported aircraft and firefighting effectiveness.<\/p>\r\n<p style=\"font-weight: 400;\">\u201cMore than 60 percent of the time, we\u2019re putting treatments in the right place,\u201d Bigelow said.<\/p>\r\n<p style=\"font-weight: 400;\">For policymakers, that statistic\u2014along with the GIS maps, photos, and standardized reports\u2014proves wildfire mitigation investments are paying off.<\/p>\r\n\r\n<h3 style=\"font-weight: 400;\"><strong>Building on Federal Foundations<\/strong><\/h3>\r\n<p style=\"font-weight: 400;\">CAL FIRE\u2019s approach builds on the foundation established by the US Forest Service\u2019s Fuel Treatment Effectiveness Monitoring (FTEM) system, which has required federal land managers to assess treatment effectiveness since 2003. The federal system mandates that agencies complete assessments within 90 days when wildfires intersect with treatments.<\/p>\r\n<p style=\"font-weight: 400;\">\u201cThe federal FTEM system was a good start, but it relied on manual data entry and post-fire reporting,\u201d Bigelow explained. \u201cWe took that concept and automated the entire front-end process. Instead of waiting 90 days and hoping someone remembers to fill out a form, our system identifies potential assessments the moment a fire starts and immediately sends the assessment tools to the field.\u201d<\/p>\r\n<p style=\"font-weight: 400;\">Proactive assessment captures data while conditions are fresh and personnel are at the incident.<\/p>\r\n<p style=\"font-weight: 400;\">An additional consideration is the maintenance challenge. CAL FIRE\u2019s data shows that after five years, most treatments lose effectiveness without maintenance.<\/p>\r\n<p style=\"font-weight: 400;\">\u201cWe\u2019ve invested over a billion dollars in grants in the last decade, but we\u2019ve lost many fuel breaks because we didn\u2019t prioritize maintenance,\u201d Bigelow said. \u201cThis year we made the decision to prioritize maintenance: If your grant application doesn't include maintenance, it will have a tougher time being awarded.\"<\/p>\r\n<p style=\"font-weight: 400;\">For agencies nationwide, this is a critical takeaway. It\u2019s not enough to fund new projects. True return on investment depends on sustaining and maintaining treatments over time.<\/p>\r\n\r\n<h3 style=\"font-weight: 400;\"><strong>Protecting Homes and Communities <\/strong><\/h3>\r\n<p style=\"font-weight: 400;\">While fuel treatments work at the landscape level, CAL FIRE has also pioneered a comprehensive home hardening program that brings protection directly to communities. This program is a Joint Powers Authority with the Governor\u2019s Office of Emergency Services. The program provides up to $40,000 per homeowner to retrofit existing homes with fire-resistant materials and features.<\/p>\r\n<p style=\"font-weight: 400;\">CAL FIRE codeveloped a hazard mitigation methodology with the research industry that prioritizes improvements\u2014roof first, then siding, then vents, then windows. The department created a retrofitting standard, working with the National Institute of Standards and Technology, the Insurance Institute for Business &amp; Home Safety, and other partners.<\/p>\r\n<p style=\"font-weight: 400;\">\u201cNobody had ever done this before,\u201d Bigelow said. \u201cThere are codes that tell you how to build a new home in wildfire areas, but nothing that says what you have to do to an existing home. Collectively, we had to create that from scratch.\u201d<\/p>"},{"acf_fc_layout":"gallery","gallery_images":[768762,768760,768761]},{"acf_fc_layout":"content","content":"<p style=\"font-weight: 400;\">So far, CAL FIRE has retrofitted 93 homes across six pilot counties, using GIS and other technologies to automate workflows from application through inspection. The home hardening program was designed to be transferable. It provides a complete toolkit others can implement using their own funding sources.<\/p>\r\n\r\n<h3 style=\"font-weight: 400;\"><strong>Predictive Modeling and the Future<\/strong><\/h3>\r\n<p style=\"font-weight: 400;\">CAL FIRE is now partnering with other organizations to model where treatments will provide the most benefit in the future. By factoring in ignition history, road networks, watershed values, biodiversity, and even carbon sequestration, the models help decision-makers prioritize where to invest.<\/p>\r\n<p style=\"font-weight: 400;\">\u201cThe beauty of this system is that you can dial up different priorities,\u201d Bigelow said. \u201cWant to focus on communities? The model analyzes the wildfire exposure to structures. Want to emphasize environmental protection? It looks at smoke, carbon, watersheds, and ecosystem health. And it gives you the cost estimate based on real-world grant data.\u201d<\/p>\r\n<p style=\"font-weight: 400;\">That kind of predictive, data-driven planning does more than strengthen California\u2019s wildfire resilience. It helps to set a template and provide inspiration for every agency seeking to justify mitigation investments.<\/p>\r\n\r\n<h3 style=\"font-weight: 400;\"><strong>The Road Ahead<\/strong><\/h3>\r\n<p style=\"font-weight: 400;\">CAL FIRE\u2019s annual operating budget has grown from under $1 million in 2004 to $4.7 billion today, and lawmakers want proof that money is being spent wisely.<\/p>\r\n<p style=\"font-weight: 400;\">\u201cIf we can\u2019t quantify the benefits in a way they understand, we won\u2019t continue to get investments,\u201d Bigelow said. \u201cWe have to be able to visualize things, show outcomes, and prove ROI.\u201d<\/p>\r\n<p style=\"font-weight: 400;\">The challenge isn\u2019t unique to California. Federal agencies, state legislatures, and local governments are all demanding evidence-based decision-making. For wildfire agencies everywhere, the takeaway is clear: If you want to secure funding, you need to prove your treatments work, maintain them over time, and tell that story with data.<\/p>\r\n&nbsp;\r\n<p style=\"font-weight: 400;\">Learn more about how <a href=\"https:\/\/www.esri.com\/en-us\/industries\/wildland-fire\/strategies\/mitigation\">GIS is applied to manage
