The inhabitants in Texas is projected to increase to almost 42 million other folks by way of 2050, the TWDB famous in its document, with a lot of this expansion going on upstream and downstream of our main metropolitan spaces. There must be a concerted effort to inspire sound land use that minimizes flood injury, in keeping with the company.

TWDB spokeswoman Merry Klonower mentioned if lawmakers enact the company’s suggestions, it will lay the root for comprehensively managing flood threats.

Developing flood maps for all watersheds and higher planning constitute “a new suite of activities and a new approach to identifying and minimizing flood risk for all Texans,” Klonower mentioned.
