Figure F.5 depicts the WUI for the Town of Garner. The WUI is the area where housing development is built near or among areas of vegetation that may be prone to wildfire. Figure F.6 depicts the Fire Intensity Scale, which indicates the potential severity of fire based on fuel loads, topography, and other factors. Figure F.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 southwest and east Garner. Some of these areas do fall within the WUI but have a lower burn probability. The area of greatest risk in the Town of Garner are in the central- eastern region where WUI overlays with moderate burn probability and moderate to high potential fire intensity levels. Table F.15 provides building counts and estimated damages for Critical Infrastructure and Key Resources (CIKR) buildings by sector at risk to wildfire hazard.
