Figure I.5 depicts the WUI for the Town of Morrisville. The WUI is the area where housing development is built near or among areas of vegetation that may be prone to wildfire. Figure I.6 depicts the Fire Intensity Scale, which indicates the potential severity of fire based on fuel loads, topography, and other factors. Figure I.7 depicts Burn Probability based on landscape conditions, percentile weather, historical ignition patterns, and historical prevention and suppression efforts. North and east Morrisville have the highest potential fire intensity in two concentrated pockets. These pockets, however, are largely outside of the WUI. The town has a relatively low burn probability, as well.
