Figure G.5 depicts the WUI for the Town of Holly Springs. The WUI is the area where housing development is built near or among areas of vegetation that may be prone to wildfire. Figure G.6 depicts the Fire Intensity Scale, which indicates the potential severity of fire based on fuel loads, topography, and other factors. Figure G.7 depicts Burn Probability based on landscape conditions, percentile weather, historical ignition patterns, and historical prevention and suppression efforts. Potential fire intensity is highest in northwest and west Holly Springs. These areas are largely outside of the WUI and have low burn probability. Southeast Holly Springs has a moderate burn probability, however potential fire intensity is relatively low in most of the area.
