Public Invited to Appeal or Comment on Flood Maps for San Marcos Watershed: Caldwell, Gonzales, Guadalupe, and Hays Counties

Release date:

R6-18-003

Denton, Texas– New preliminary flood risk information and updated Flood Insurance Rate Maps (FIRM) are available for review by residents and business owners in Caldwell, Gonzales, Guadalupe, and Hays counties. Officials encourage property owners to review the latest information to learn about local flood risks and potential future flood insurance requirements. Community stakeholders can identify any concerns or questions about the information provided and participate in appeal and comment periods for the maps.

The new flood risk information and FIRM resulted from a long-term flood study lead by a team of local community, state, Federal Emergency Management Agency (FEMA), and U.S. Army Corps of Engineers officials. Significant community review has already taken place, including flood risk open houses in August 2017 where residents and business owners in the affected counties were able to learn more about the new preliminary flood risk information and view the maps.

The detailed digital maps show current flood hazards for communities within portions of the San Marcos and Austin-Travis Lakes watersheds and replace flood maps that are based on outdated studies and technology. The maps provide more precise flood hazard information for those areas, including places affected by the devastating Memorial Day 2015 floods and five other major floods since 2000.

The deadlines for submitting appeals or comments are:

  • Gonzales County: April 22, 2018
  • Guadalupe County - Staples and unincorporated areas: April 23, 2018
  • Hays County - Buda, City of Hays, Kyle and Mountain City: April 23, 2018
  • Hays County – Austin, Bear Creek, Dripping Springs, San Marcos, Wimberley, Woodcreek and unincorporated areas: April 24, 2018
  • Caldwell County: April 24, 2018
  • Guadalupe County – City of Luling: April 24, 2018

If property owners see incorrect information that does not change the flood hazard information—such as a missing or misspelled road name or an incorrect corporate boundary—they can submit a written comment. They can submit an appeal if they perceive that modeling or data used to create the map is technically or scientifically incorrect. An appeal must include technical information, such as hydraulic or hydrologic data, to support the claim. Appeals must be submitted through the office of the county or local community floodplain administrator.

In addition to viewing the preliminary maps at their local floodplain administrator’s office, residents and business owners may:

The next step in the mapping process is the resolution of all comments and appeals. Once they are resolved, FEMA will notify communities of the effective date of the final maps, which is targeted for spring 2019.
