(Photo credit: American Red Cross) Opposite Page: Painting of Harris Fire by Kate Dore, based on photo by Wes Schultz. 2 Introductory Statement In October of 2007, a series of large wildfires ignited and burned hundreds of thousands of acres in Southern California. The fires displaced nearly one million residents, destroyed thousands of homes, and sadly took the lives of 10 people. Shortly after the fire siege began, a team was commissioned by CAL FIRE, the U.S. Forest Service and OES to gather data and measure the response from the numerous fire agencies involved. This report is the result of the team’s efforts and is based upon the best available information and all known facts that have been accumulated. In addition to outlining the fire conditions leading up to the 2007 siege, this report presents statistics —including availability of firefighting resources, acreage engaged, and weather conditions—alongside the strategies that were employed by fire commanders to create a complete day-by-day account of the firefighting effort. The ability to protect the lives, property, and natural resources of the residents of California is contingent upon the strength of cooperation and coordination among federal, state and local firefighting agencies.

We use the 2007 fires as a case study to draw three major lessons about southern California, but, at the same time, wildfires and wildfire complexity in southern California. First, the great majority of large fires in expansion of housing into these fire-prone southern California occur in the autumn under the influence of Santa Ana windstorms. These fires also wildlands continues at an enormous pace cost the most to contain and cause the most damage to life and property, and the October 2007 fires (Safford 2007).

  • CAL FIRE Border Impact Statistics
    BORDER AGENCY FIRE COUNCIL The Harris Fire Year End Report 2007 1 2 What is BAFC? – The concerned citizens of the United States and Mexico formed the Border Agency Fire Council. It is a consortium of government and private entities, emergency responders, environmental specialists, law enforcement, fire protection, and elected officials. It began under emergency conditions and has proven to be an extremely successful collaboration. People are alive today because of BAFC. Threatened habitat is protected and even improved because of this program. An unprecedented bi-national mutual assistance agreement is in place and working because of this program. The members of BAFC have worked without judgment or malice toward their fellow human being. From the beginning, their motivation has been primarily to save lives and protect the sensitive habitat of the border area. Thirty-four organizations make up BAFC; a list of members is at the end of this report. The members meet quarterly during the winter and every six to eight weeks during fire season. They meet at the San Diego headquarters of the California Department of Forestry and Fire Protection (CAL FIRE) in El Cajon, California. Through collaborative effort, they have altered the environment to allow better access into the wildland for emergency responders, while respecting the natural values of the area. They have enhanced communication among emergency responders on both sides of the U.S. - Mexico border. They have reached out to people in both countries with safety messages in Spanish and English. This report provides a brief description of the many projects the Council and agencies have accomplished this year and ongoing projects started in other years yet still active today.

  • Evaluating the Ability of FARSITE to Simulate Wildfires Influenced by Extreme, Downslope Winds in Santa Barbara, California
    fire Article Evaluating the Ability of FARSITE to Simulate Wildfires Influenced by Extreme, Downslope Winds in Santa Barbara, California Katelyn Zigner 1,* , Leila M. V.

We used the wildfire spread model Fire Area Simulator (FARSITE) to simulate two wildfires influenced by strong wind events in Santa Barbara, CA. High spatial-resolution imagery for fuel maps and hourly wind downscaled to 100 m were used as model inputs, and sensitivity tests were performed to evaluate the effects of ignition timing and location on fire spread. Additionally, burn area rasters from FARSITE simulations were compared to minimum travel time rasters from FlamMap simulations, a wildfire model similar to FARSITE that holds environmental variables constant. Utilization of two case studies during strong winds revealed that FARSITE was able to successfully reconstruct the spread rate and size of wildfires when spotting was minimal.

  • The Economic Impact of the October 2007 Southern California Wildfires
    The Economic Impact of the October 2007 Southern California Wildfires Employment Development Department Labor Market Information Division December 2007 Contacts: Steve Saxton (916) 262-2160 Joel Hessing (916) 262-2241 OVERVIEW The Southern California wildfires of October 2007 affected lives and businesses in seven Southern California counties: Los Angeles, Orange, Riverside, San Bernardino, San Diego, Santa Barbara, and Ventura. The fires’ severity prompted Governor Arnold Schwarzenegger to travel to many of the fire areas and declare a state of emergency in the seven counties as firefighters from all over California traveled to the stricken area to help fight the fires. President George W. Bush declared a federal state of emergency for the affected counties. In the following days, both the president and the Governor toured declared areas. The federal emergency declaration allowed federal help with firefighting, evacuation, and emergency protection measures. The subsequent federal major disaster declaration provided funds for Individual Assistance programs, Public Assistance programs, and Disaster Unemployment Assistance programs, which provides funds to workers (including self-employed and farmers) who were placed out of work as a result of the disaster. As part of the Employment Development Department’s (EDD) response to this disaster, the Labor Market Information Division (LMID) gathered information from many sources related to the economic impact of the wildfires. On November 1, 2007 the California Office of Emergency Services (OES) reported that the fires had destroyed 2,180 residences, 922 outbuildings, and six commercial buildings. Twenty-three separate named fires burned approximately 518,021 acres (809.4 square miles). (The Labor Market Information Division based this report on those data and Appendices A and B provide detailed information on each separate fire.) The LMID identified 3,135 firms within the fire perimeters.

More recently, with the catastrophic wildfire events of 2017 and 2018, fire has emerged as an annual threat roughly comparable to floods. Fire and flood fire hazards are surpassed only by high magnitude earthquake hazards, which typically occur less frequently but can result in extreme disaster events. For the 2018 State Hazard Mitigation Plan (SHMP), the fire hazards risk assessment has been expanded to include separate discussions on wildfire hazards and structural fire hazards. Structural fire hazards can occur as a cascading hazard emerging from wildfires or earthquakes, or as an independent hazard event. In either case, fire hazard mitigation actions are crucial in minimizing potential risk. Preparation and implementation of Local Hazard Mitigation Plans (LHMPs) with linkage to a jurisdiction’s general plan, play an important role in the fire mitigation process.
