Hays County Hazard Mitigation Plan - Executive Summary Hazards and Risks Chapter 2 of the main plan document includes hazard description and extent scale information, which apply to all participating communities. The State of Texas Hazard Mitigation Plan was used as the source of data for the hazard description information. Hazard location maps, community extent, history of significant events, probability of future events, as well as impact and vulnerability summaries can be found in Section 2 of each Community Annex for hazards that are not regional in nature. All hazard profile elements for hazards that occur on a regional scale where county-wide data application was appropriate for all profile elements are contained within Chapter 2 of the main plan document rather than individual community annexes.
