M.1.4 WILDFIRE Table M.5 summarizes the acreage in the Town of Zebulon that falls within the Wildland Urban Interface (WUI), categorized by housing density. The WUI is the area where housing development is built near or among areas of vegetation that may be prone to wildfire. Areas in the WUI are those where development may intermix with flammable vegetation. Over 23 percent of the Town of Zebulon is not included in the WUI.

Figure M.5 depicts the WUI for the Town of Zebulon. Figure M.6 depicts the Fire Intensity Scale, which indicates the potential severity of fire based on fuel loads, topography, and other factors. Figure M.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 the north, east, and western regions of Zebulon outside of the Town center; however, these areas are largely outside of the WUI and have low burn probabilities. The area with the highest burn probability, in northwest Zebulon, does not overlay with high potential fire intensity and is partially outside of the WUI. Table M.6 provides the count and estimated value of all structures that intersect with areas of the Town of Zebulon that are rated moderate to high on the WUI Risk Index.
