The Onion Creek Flood Study has two main goals: to update the floodplain maps for Onion Creek and to evaluate options to reduce flooding in the Onion Creek Neighborhood.
Options to Reduce Flooding in the Onion Creek Neighborhood
The feasibility study about alternatives to reduce flooding near Pinehurst Drive and Wild Dunes Drive is nearing completion. The different alternatives were presented at a public meeting on May 16, 2017. Download the presentation and the posters/fact sheets to find out more about the different possibilities:
Onion Creek is Austin’s largest watershed. In fact, most of the watershed is outside of Austin in Hays County. The floodplain study focuses on the part of Onion Creek within Austin and Travis County. It also looks at three of the creeks that feed Onion Creek: Bear, Little Bear and Rinard.
For flood mitigation, the next steps are to complete the current analysis of the options, select an option and identify funding. The timeframe for implementation of the selected option is unknown at this time.
