6.2.2 Case Study #2: 2003 Southern California Fire Complex

“It was no longer ‘do what you can to protect the structures’ it was ‘do what you can to get these people out and to a place of safety’…”. Fox, 2013.

From its soils to its ecology, to its place and indigenous tribal names, California, and in particular its southern region is laden with geological, ecological, anthropological, and etymological clues that point to a fiery past. But for one species, fire would pose not a problem to the region, that species being H.sapiens, or more specifically, our present wildland urban interface architectural paradigm, which having regionally absorbed an area some 30-fold greater than in the late 1880s (Keeley et al, 2004) is at systemic odds with the regional fire regimes.

The scientific institutions of the 21st century endowed with sizeably greater real-time environmental data than they of 3-decades ago, that October 2003 would deliver one of the most intense fire seasons in decades came as no surprise, for state-wide, Remote Automated Weather [RAW] station readings read ‘extreme fire-weather’. However, when so many are the variables that impact upon the spread, intensity, and severity of wildfires, none could anticipate the moment-to-moment events as would unfold.

All, as yet identified, sources of ignition within the fire complex human-caused, including the lighting of a signal flare, and two cases of arson, the sCA October 2003 fire complex became emblematic of the dichotomy at the boundary of socio- ecological systems. As several of the region’s fire-adapted landscapes ignited into flame, species of which the reproduction is dependent thereupon propagated the fire through their various pyrotechnic endurer, evader, and resister functional traits, as simultaneously, both regional and national fire crews, comprised men and women from institutions as diverse as military troops, prisoners, and community volunteers mobilised to fight the fires.

As in London in September 1666, while a combination of people power and equipment saved some residences and businesses, 3,631 homes were destroyed, and yet more were damaged (FEMA, 2004) [Fig. 66]. However, though many were the properties lost to the 740,000 acres-wide fire complex, relatively few [22] lost their lives, the matter thereof a testament, to amongst others things, state agencies’ capacity to co-ordinate mass evacuations on barely any notice. Practice, the saying goes, ‘makes perfect’, which is pertinent because just four years later sCA would need implement a wildfire evacuation of even greater proportions.

Federal Response:

 

77 Fires Crews; 19 Air Tankers; 36 Helicopters; 6 Federally sponsored National Interagency Incident Management Teams; over 1,000 support staff and communications equipment; fuels reduction in most at-risk WUI areas [1].

 

Federal Response Plan activated:

 

October 27th 2003.

Support Functions Provided:

 

Transport; Communications; Public Works & Engineering; Firefighting; Information and Planning; Mass Care; Resource Support; Health and Medical Services; Urban Search and Rescue; Hazardous Materials; Food; and Energy [1].

 

Hazards During Fires include:

 

Loss of life and injury to residents, firefighters; threat to life and/or displacement of pets and livestock; respiratory problems due to poor air quality; loss of property to fire and/or looting [3].

 

Hazards Post-fires include:

 

Additional arson; looters; theft of fire-fighting equipment; falling trees and debris; mudslides; rockslides [3].

Further Post-Fire Impacts include:

 

Loss of utilities including power and/or water; closures of civic services and businesses; delayed mail delivery; housing shortages; fraud by both individuals and businesses; disruption to education, sports activities, and other daily activities; loss of income, and emotional trauma [3].

* While no properties burned, over 350 homes and 40 businesses had been at risk, together with electrical transmission lines, and an oil field.

**Combined Federal, State, and Local Government and Private Organisations, inc. losses by both private insurers and government-sponsored programs.
