Drought: Location Drought occurs on a regional scale. The entire planning area is equally at risk as it can occur anywhere within the participating communities. Drought: Previous Occurrences NOAA Storm Events Database documents 27 drought events for Hays County since the year 1996. Although there were no drought events reported specifically for individual incorporated jurisdictions within the County, all participating communities would have been affected by the events that were reported for the surrounding County area. The US Drought Monitor Drought Intensity scale classifies drought by 5 categories shown in Table 2.2, D0 through D4. According to the reported drought occurrences, the maximum drought extent experienced is a Category D4 drought. Based on 6 years with reported drought events from the NOAA Storm Events Database within 20 years, a drought event occurs approximately once every 3 years on average in Hays County. All participating communities are assumed to experience drought reported for the surrounding County areas, and therefore can expect a drought event approximately once every 3 years on average, up to a Stage D4. 28
