The Big Question:The Big Question:
How did we do?How did we do? Everyone has asked how well the CDS Everyone has asked how well the CDS
Wildfire Hazard Model predicted the Wildfire Hazard Model predicted the areas that would burnareas that would burn
Can mapping technology and CDS’s Can mapping technology and CDS’s Wildfire Model accurately identify Wildfire Model accurately identify potential brush hazards?potential brush hazards?
The Answer:The Answer:
Yes!Yes! CDS did an CDS did an excellentexcellent job of identifying job of identifying
areas that were at risk of wildfiresareas that were at risk of wildfires The following pages explain our analysis The following pages explain our analysis
and the results of the analysisand the results of the analysis
AnalysisAnalysis CDS looked at fire extents dated Oct 27 CDS looked at fire extents dated Oct 27
through Nov 4 (busiest fire period during through Nov 4 (busiest fire period during the outbreak)the outbreak)
We looked at 5 counties in Southern CA We looked at 5 counties in Southern CA (Los Angeles, Riverside, San Bernardino, (Los Angeles, Riverside, San Bernardino, San Diego and Ventura)San Diego and Ventura)
We compared the Renie Admap books to We compared the Renie Admap books to the CDS Wildfire Model to the areas that the CDS Wildfire Model to the areas that actually burned to see how well we actually burned to see how well we predicted the firespredicted the fires
We overlaid the fire extents on the Renie & CDS Wildfire Models. This shows what the entire Southern California area looked like on a macro scale.
