The third and final phase of drainage improvements in Northwest Austin that began four years ago are expected to break ground in the coming weeks.

Williamson County will soon begin Phase 3 of the Forest North drainage improvement project, located at the northeast corner of the intersection of Anderson Mill Road and Pond Springs Road, according to a May 20 news release.

Construction will begin by the end of spring this year, and Williamson County states it expects this construction to be completed before spring 2022, weather permitting.

These improvements will address flooding issues in this area, according to Williamson County. Over the course of construction, crews will replace broken and deficient culverts and will grade channels to improve stormwater flow and absorption capacity, according to county documents.

Construction on Phase 3 of the Forest North drainage improvement project will be split into seven neighborhoods. A full map of those zones can be found on Williamson County’s website.


All project updates, including land and road closures, will be posted on the Forest North drainage improvement project section on the county’s website.

This final phase of drainage improvements is funded by Williamson County’s 2019 Road Bond Program. County officials estimate the project will cost approximately $4.8 million.

“This is the first construction project of the 2019 voter-approved Road Bonds for the County and the final phase of a comprehensive drainage system for this fairly flat region of Precinct 1,” Williamson County Precinct 1 Commissioner Terry Cook said in the May 20 news release.

Construction for the first two phases of the Forest North drainage improvement project began in 2016. Design for all phases of the drainage improvements were included in Williamson County’s 2013 Road Bond Program, according to the county’s website.
