Figure H.5 depicts the WUI for the Town of Knightdale. The WUI is the area where housing development is built near or among areas of vegetation that may be prone to wildfire. Figure H.6 depicts the Fire Intensity Scale, which indicates the potential severity of fire based on fuel loads, topography, and other factors. Figure H.7 depicts Burn Probability based on landscape conditions, percentile weather, historical ignition patterns, and historical prevention and suppression efforts. Areas of high potential fire intensity are scattered throughout Knightdale and overlap with areas of the WUI in the southern and northeaster portions of the town. However, burn probability is low throughout the town, meaning development in these areas is at low to no risk. Table H.14 provides building counts and estimated damages for Critical Infrastructure and Key Resources (CIKR) buildings by sector at risk to wildfire hazard.
