The City of Austin’s Watershed Protection Department today announced the completion of floodplain studies for several watersheds. The studies will result in updated flood maps. The watersheds affected include:
- Boggy Creek
- Bull and West Bull Creek
- Carson Creek
- Cottonmouth Creek
- Dry Creek East
- Fort Branch
- Shoal Creek
- Tannehill Branch
The City chose these watersheds for the study because the existing flood maps were based on outdated information, or there were no previous flood maps along certain tributaries.
The overall goal of updating these studies is to make sure the City and the public are aware of the flood risks that may affect them. The studies show that in some places the floodplains have expanded and in other places they have been reduced. More specifically, the expanded floodplains include approximately 2,400 additional properties and 800 additional buildings. However, in areas where the floodplains have been reduced, approximately 2,200 properties and 400 buildings are no longer considered to be in the floodplain.
“The new maps will help us make more informed decisions about how to protect our community from the dangers of flooding,” said Kevin Shunk, manager of the City’s Floodplain Office. “Even though Austin is in a period of severe drought, flooding still poses serious risks to our community. I hope that the public will use this information to take steps to protect their family and property.”
These latest studies incorporate the best available information so that we have the most accurate understanding of the floodplains within these watersheds. The City will also use the new flood maps to regulate development in the floodplain. FEMA will begin using the updated flood maps for flood insurance purposes in 2015 following a public comment and appeal period.
The public can review the changes on our online map, find out more at www.austintexas.gov/floodplainchanges or by calling 512-974-2843. In addition, there will be three public meetings in different parts of the city for residents to ask questions and get more information. It is important for the public to understand that the new floodplain maps might affect the types of modifications that can be made to a house; whether flood insurance is required; and most importantly, the need to prepare your family or business for a flood.
Public Meetings to View and Discuss the Updated Flood Maps
Residents and business owners are encouraged to attend one of three public meetings to learn more about the study, how the proposed new flood maps will be used, and the steps they can take to protect themselves from flood damage.
