Creek Flooding
Austin has numerous creeks throughout town. All are subject to flash flooding. The creek flooding program undertakes projects to protect lives and reduce property damage when these creeks overflow their banks.
This program plans and constructs many different types of projects, including:
- Detention ponds
- Improvements to low water crossings
- Flood walls
- Channel widening
- Buyouts of homes most at risk of flooding, which is often the most cost-effective solution to flooding.
The program also inspects 100s of small dams to ensure their safety. Many need upgrades. A few have already been improved, and several more are in the planning stages. Staff also handle drainage easement releases and licensing.
