San Diego Fires 2003: Rapid Assessment of Post-Fire Impacts Track: EMS, Fire and Disaster Management Author(s): Brian Hitchens, Douglas Isbell, Cid Tesoro, Nathan Jacobsen, Marcus Quigley Southern California was devastated this past fall with a series of sweeping wildfires, which blackened in excess of 375,000 acres of land. GeoSyntec Consultants assisted the City and County of San Diego in implementing a rapid assessment of fire damage and potential for debris flows following impending rain events. Data was collected from field teams employing GPS enabled ruggedized PDAs. This data was then assimilated directly into a database/ArcGIS system. To assess the overall potential for increased erosion response, theSpatial Analyst extension was used to integrate slope, soil type, and burn severity data to produce a Post-fire Hazard Index of Relative Erodability(PHIRE) map.This paper provides an overview and sites specific examples of the tools and techniques applied as well as a summary of lessons learned and a discussion of the appropriateness of the technologies as a function of the magnitude and complexity of the task at hand.
