Part 2 of the 2016 WUI Webinar

This webinar examines how multiple GIS strategies were employed to analyze changes to fire risk in 3 nearby, but demographically different communities in San Diego County. This research simultaneously (1) quantifies expansion of the WUI over time in multiple, dissimilar communities, (2) analyzes temporal changes to risk based on altered wildfire exposure and structural characteristics such as roofing materials, defensible space, and housing density, and (3) compares potential social factors influencing compliance of state fire regulations. 

The information generated from this study provides new and innovative methodologies to examine risk in fire-­prone communities and also demonstrates the need to develop alternate mitigation approaches based upon site-­specific conditions.
