Join us at our monthly happy hour to learn about a new federal rainfall study called Atlas 14 and its implications to our understanding of flood risk in the City of Austin. Based on Atlas 14, portions of Texas, including the City of Austin, are more likely to receive severe rainfall events.

This has important implications to Austin residents, public and private infrastructure, and development city-wide. More buildings, homes, and roadways in Austin are now known to be at risk of flooding. Flood insurance for some Austin residents may be required or be more expensive after federal floodplain maps are updated in three to four years. Certain City infrastructure such as roadways and wastewater treatment plants is now at more risk of flooding than previously thought.

In response to this new understanding of flood risk, the Watershed Protection Department proposes amendments to the Land Development Code. The intent of these code amendments is to reduce the impact of flooding on Austin residents.
