Assessment of PG&E High Fire Risk Area Map

We have participated in the assessment of PG&E high fire risk area mapping and PG&E public safety power shutoff descoping framework. Using the big data system, we worked to modify the Tier 2 (elevated risk) and Tier 3 (extreme risk) areas on the California Public Utilities Commission (CPUC) High Fire-Threat District Map to meet PG&E’s demand for its Public Safety Power Shutoff project. We conduct analyses of spatial data including electric wire distribution, historic fire cases, flammability, and declivity of vegetative cover, as well as satellite images with GIS to review over 800 polygons throughout northern California and estimated whether the polygons should be added into or removed from the risk area.
