AUSTIN (KXAN) — City engineers have a plan to keep a landslide along Shoal Creek in central Austin from getting worse after it started nearly three weeks ago. As they work on implementing that long-term solution, the city says the landslide is currently stable.
Experts call this type of landslide a “rotational slide,” which means the land that fell from the top slid down an angled “glide plane.” That, in turn, pushed concrete from the trail below and trees into Shoal Creek.
In a briefing Friday, city engineers said a solution is multi-pronged. The city wants to drive ground anchors into the clay and down into the limestone. Soil nails will also be added to the side of the landslide to help stabilize the ground. At the bottom, there will be a material installed to stabilize the bottom along the creek.
Once construction starts, it could take up to 12 weeks to complete. The city will also have to replace the wastewater line and rebuild the trail.
In the meantime, the city has put up fencing and signs around the landslide to keep onlookers away from the site. The city says it is also working with homeowners to keep them abreast of the changes and developments.
