Service Description: A model characterizing wildfire risk based on wildfire hazard (Tukman, 2020), ember load index (Pyrologix, 2020), structure density (Microsoft, 2020), and road network rank. This is version 6c of the data layer.

Description: This vector layer contains the values used to derive a wildfire risk index (WRI) for Sonoma County. The final WRI is derived from adding seven other ranks (or indices)for the following parameters:
1. Sonoma Wildfire Hazard Index - average value for pixels falling within each hexagon - this layer was derived from a number of layers including: predicted flame length, fire weather potential, road network, location of electrical transmission lines, and suppression difficulty (USFS).
2. Average of Sonoma Wildfire Hazard Index within 1 Mile of each hexagon
3. Pyrologix's Ember Load Index - average value of pixels falling within each hexagon
4. Average of Pyrologix's Ember Load Index within 1 Mile of each hexagon
5. Structure Density Index - based on the number of structures found within each hexagon and classed into quantiles
6. Average Structure Density Index within 1 Mile of each hexagon
7. Road Network Rank - based on a 2019 evacuation analysis conducted by Kevin Lacefield with Sonoma County ISD.
Version 6c of this data layer also includes an average of the final WRI found within 1 mile of each hexagon. Structure index was corrected for selection errors.
