In response to an extreme flooding event in October 2015 on Onion Creek and Dry Creek East, Travis County developed a comprehensive watershed study simulating the event in order to evaluate flood mitigation alternatives that could improve public safety. The study focused on five neighborhoods that were greatly affected by repeated flooding: Thoroughbred Farms, Arroyo Doble, Onion Creek Meadows, Twin Creeks, and Bluff Springs. The final report has been completed and is now available.
