In February 2003, the Hays County Commissioners Court approved procedures for preparation of the Hays County Mitigation Plan that includes Hays County and all eleven (11) incorporated -Signatui"e/D~te communities. The Hays County Commissioners Court selected Halff Associates, Inc. to act as II This Checklist Completed By John Ivey, PE, CFM, Halff Associates, Inc., 2127/04 planning consultants for the project. The consultants were tasked with assisting in the preparation of the countywide Mitigation Plan documerit to include the following communities:

• Hays County (unincorporated) • Village of Bear Creek • City of Buda City of Dripping Springs • City of Hays • City ofKyle City of Mountain City City ofNiederwald • City of San Marcos • Township ofUhland • Village ofWimberley City ofWoodcreek

Hays County and Incorporated Areas are vulnerable to several natural and technological hazards. In order to address the hazards faced, Hays County prepared the 2001 Hays County Emergency Management Plan. The Mitigation Plan will complement the current Emergency Management Plan. Additionally, the floodplain mitigation portion of the plan can be utilized for Community Rating System (CRS) purposes by Hays County and individual communities.

Mitigation is characterized as a long-term, on-going process. This plan seeks to address all hazards within the County. It provides general guidance related to hazards within the County and incorporated communities as well as providing an overview of the mitigation efforts undertaken by the County and participating communities. In addition, the plan identifies potential problematic conditions and outlines corrective actions that the County and participating communities can undertake to remedy the identified problems. Planning and implementation actions are identified that are applicable to both pre-incident and post-incident situations.

The Mitigation Plan is more than just another planning docwnent It is a dynamic record of each community's. recognition of its vulnerability to hazards, determination of the risks associated with hazard effects, and commitment to reducing the long-term consequences of flood hazards. The mitigation plan outlines mitigation goals within Hays County and each community, identifies risk reduction strategies for hazards that threaten the area, and discusses the ongoing risk reduction activities undertaken within each jurisdiction. The Hays County Mitigation Plan is designed to meet the planning requirements for FEMA's Community Rating

It is bordered by Travis County to the northeast, Blanco County to the west, Comal County to the southwest, and Caldwell County to the southeast. It is situated between the major urban The Hays County Mitigation Planning Committee Action Items are listed in priority order in centers of Austin and San Antonio in the heart of the Texas HilI Country. The geography of Section 6, "Draft an Action Plan." Hays County is defined by the Balcones Escarpment, which cuts an arc from near the northeast comer of the county, through the City of San Marcos, to a point near the southeast comer of the county. The northwest portion is characterized by rugged hill country features and ranching/grazing land uses, with elevations up to 1200' (NGVD 1929). Blackland Prairie soils, farming, and elevations of 400' represent the area bel.ow the fault, roughly the southeast quarter of the county. Portions of the Pedemales River, Barton Creek and Onion Creek flow in the northern portion of Hays County, while the Blanco River and its tributaries, including the San Marcos River, drain the southern portion.

Hays County has experienced major development due to its close proximity to Austin and San Antonio and being bisected by Interstate Highway 35 (IH-35). Based on the 2002-2003 Texas Almanac, the Hays County population has increased significantly since 1970:

Period Growth(%) 1970-1980 46.86 1980-1990 61.63 1990-2000 48.73

During the May 2003 and June 2003 Hays County Mitigation Planning Committee meetings, Table 2, "Multi-Hazard Inventory and Risk Assessment, Hays County", was prepared listing each hazard and showing the priority level, severity, frequency and Committee Comments. [T.xDEM P-34] This infonnation is swnmarized in Table 3, "Hazard Rating Summary", which identifies the major hazards that Hays County is most likely to face. Additionally, the impacts on public heaJth and safety and the impacts on property are illustrated.

The process of identifying hazards is two-fold. First, a hazards analysis is developed. It is a stand-alone product consisting of maps, databases, charts, atlases, and other supporting documentation. The analysis provides a risk-based, quantitative method, to prioritize mitigation and preparedness needs for the jurisdiction as a whole. This analysis will be reviewed and updated annually. The Hays County Multi-Ha7.3.rd Inventory and Risk Assessment was completed by Halff Associates, Inc. in December 2003 [P-34). Individual Hazard Worksheets is included in Attachment "D" of this Plan.

The mitigation action plan outlines mitigation ---·- -• ••- ~ -v--• - ·------goals, identifies a risk reduction strategy for each of the significant hazards that threaten the Flooding area, and discusses the ongoing risk reduction activities undertaken within the jurisdiction. The HAZMAT Release mitigation action plan further details what is to be done, how much it will cost, who will be Substantial Urban Fire Transportation responsible for the action, how it will be funded, and provides an implementation schedule.

The list of counties also included Bastrop, Blanco, Burnet, Caldwell, Travis and Williamson. Hurricanes and tropical stonns combine size and intensity to become one of Earth's greatest and most awesome weather vehicles of death and destruction. In addition to hurricanes and Additional information regarding flood and other disaster events in Hays County is located in tropical stonns, damage may be caused by tornadoes that are created from the storms.

These storms are also pressure. Near the center, hurricane winds may gust to more than 200 miles per hour. capable of producing straight-line winds and microbursts with extreme power. Thunderstorms kill more people in the United States than any other phenomenon. While hurricane winds do much damage, the storm surge and torrential rains accompanying hurricane landfall are responsible for most deaths. Historically, drowning has been the greatest The heavy rains associated with thunderstorms often cause flash flooding. Due to the steep cause of hurricane deaths. The storm surge raises wave heights and increases tides. Hays terrain, flash flooding is a 1najor hazard and flood related deaths are frequent occurrences in County is located 130 miles from the Texas Gulf Coast and subject to torrential rains from Central Texas. There are numerous low water crossings in Hays County, and the Hays County tropical storms that cause both flash flooding and sustained flooding in the area Mitigation Planning Conunittee identified a Mitigation Plan Action Item to identify and adequately mark these areas.

Hays County is located in two regions as defined in the Te:xas Water Plan - Water for Texas 2002. Areas in Hays County north of Onion Creek are located in Lower Colorado Region K and areas south of Onion Creek are located in South Central Texas Region L.

Historically the cities of New Braunfels, San Antonio and San Marcos have relied on groundwater from the Edwards-Balcones Aquifer, which affects the base flow of the Guadalupe River. The City of New Braunfels has converted from groundwater to surface water from Canyon Lake. The City of San Marcos and GBRA recently constructed a pipeline and water treatment plant to also convert the City's primary water source to Canyon Lake water. As stated in the Texas Water Plan, the long range water goals for the region include: protection of the San Marcos Springs from over­ pumpage of groundwater, improved aquifer recharge; and construction of additional water supply projects to meet water needs until 2050.
