WilCo unveils Atlas 14 flood study findings

County to hold public discussion of the results, including June 5 at the Dicky-Givens Center in Taylor

The  preliminary results of the Atlas 14 floodplain study were presented  to the Williamson County Commissioners Court on May 21.

Preliminary results show the county’s 100-year flood shifted from 8-10 inches of precipitation to 10-12 inches. A 100-year flood is defined as an event that has a 1% chance of happening in any given year. For Williamson County, this change means there may be an increased risk of flooding if a 100-year event occurs.
 
 Williamson County’s Atlas 14 study includes the following findings:

• • Updating flood plain information throughout the county with the most recent scientific data, including NOAA Atlas 14 rainfall.
• • Modeling streams and waterways that have never been studied.
• • Gathering accurate information about topography, drainage structures and bridges.
• • Developing mitigation measures.

The study maps can be viewed via the link below.
