Last Updated on January 30, 2024

Derek Boese, JD, PMP General Manager

The San Antonio River Authority (River Authority) is committed to safety, and as the Authority on flood safety, we perform a crucial role in the San Antonio River Basin as a cooperating technical partner for the Federal Emergency Management Agency (FEMA). This role is also critical to our mission – keeping the San Antonio River Basin safe, clean, and enjoyable. This winter, the River Authority hosted 13 open houses throughout Bexar County for the public to view new draft floodplain maps alongside a River Authority engineer. Over 271 households from Bexar County interested in understanding their flood risk attended the open houses, with River Authority engineers dedicating over 300 hours to make these events successful and informative. Thank you to everyone who helped to make these events possible and to the community for attending these events to speak with River Authority engineers and representatives from the cities of San Antonio, Live Oak, Leon Valley, and Saint Hedwig, as well as Bexar County and the Texas Water Development Board.

The River Authority has been updating the floodplain maps using the National Oceanic and Atmospheric Administration’s (NOAA) updated rainfall estimates, ground surface elevation data from the Texas Natural Resources Information System (TNRIS), and the latest land use data for our community. Due to the constantly changing nature of floodplains, it is essential to keep the regulatory floodplain maps as current as possible. Like rivers and creeks, floodplains are dynamic and are influenced by rainfall, development, and bigger-picture climatic shifts. Updating floodplain maps gives individuals and businesses important flood risk information about their likelihood of experiencing significant rain events.

I encourage you to visit the draft floodplain viewer to learn about your updated flood risk, making informed decisions on flood insurance, and how best to protect your property. In late 2024, the River Authority will have draft floodplains for communities in the southern basin of Wilson, Karnes and Goliad counties. The River Authority will hold open houses in the southern basin before FEMA formally adopts the maps. There will also be a separate public outreach and formal appeals process led by FEMA closer to the maps’ formal adoption. We anticipate the River Authority open houses will be approximately 18 months before FEMA’s formal adoption and appeals processes. We intend to give everyone ample opportunity to make safe, flood-risk-informed decisions.

As we head into the summer and beyond, we continue our commitment to safe, clean, and enjoyable creeks and rivers. We also invite you to take advantage of the beautiful spring weather to get out to the river and enjoy many recreational opportunities on parks and trails throughout the river basin.

See you at the river,

Derek
