Construction continues on Waller Creek Tunnel project

Posted: Updated:

After nearly a year and a half of construction, we're getting a look at the new flood prevention project at Waller Creek, which could save 28 acres of downtown Austin from flooding if a big storm hit.

This is what the park is supposed to look like. There's going to be a pond at this site that will sit on top of the main facility.

Underneath it is the entrance to the more than a mile long tunnel that will send the excess water underneath downtown Austin and into Lady Bird Lake.

This is the first system of its kind in Texas and it actually dissolves floods, rather than re-directing them. The facility will also be able to handle 3.7 million gallons of water per minute, which is really important because Austin is in the heart of flash flood alley and creeks can flood in less than an hour.

"By building the tunnel, the obvious benefit is that by taking the water down underground and having it flow essentially under downtown and come up safely at Lady Bird Lake, we're protecting 40 structures and structural roadways from flooding."

The project is expected to be completed at the end of 2014.

Another cool thing about the final project is that whenever it's not raining, the tunnels can pull water from the lake to circulate it into a water fall at Waterloo Park.
