The 2013 Verisk Wildfire Risk Analysis used data from FireLine™, powered by AER™ technology, Verisk’s wildfire risk management tool for insurers to assess wildfire risk at the address level. It uses advanced satellite data processing to determine the impact of three factors that contribute to wildfire risk:

  • Fuel — Grass, trees, or dense brush feed a wildfire.
  • Slope — Steeper slopes can increase the speed and intensity of wildfire.
  • Access — Dead-end roads can impede firefighting equipment.

FireLine identifies properties located in Special Hazard Interface Areas, indicating an increased likelihood of wind-borne embers and high heat from nearby fuels.


* Number of households is based on data from the 2010 U.S. Census.
** Rounded to the nearest 100
