This project will reduce flooding for houses and roads near Little Walnut Creek between Metric Blvd. and Rutland Dr.  It includes a pipe to carry floodwaters, pond improvements at Quail Creek Park and upgrades to water and wastewater pipes.

Project Status

On January 27, 2021, the Austin City Council approved a $19.7 million construction contract for this project. We are finalizing details and the construction schedule with the contractor. We would like to hold a virtual meeting with residents of the neighborhood to explain the project. Details of this meeting will be forthcoming.

Map of Proposed Project Alignment

Floodwater will be diverted to a large box culvert that will run under Mearns Meadow Boulevard. A box culvert is a rectangular-shaped pipe installed under the road. The proposed box culvert would run from Quail Valley Boulevard to the Mearns Meadow Detention Pond in Quail Creek Park.

The project will reduce the number of houses at risk of flooding. Although some houses and one road will likely continue to flood in very heavy rainfall, the intensity and depth of flooding for these houses will still be reduced.

Construction Time Frame

Construction will start in the spring of 2021.

Estimated Budget

$19.7 million for construction
