February 20, 2018 (Williamson County, TX) – The Texas Commission on Environmental Quality (TCEQ) approved Williamson County’s plan to stabilize the cave entrance on Cambria Drive and create a new cave cover. The prior cover was a temporary solution to secure the entrance, but was warping and sagging in the wet weather conditions. The new cover is structurally designed to be in place for various weather conditions over several weeks.
Tuesday morning, workers began using an excavator to stabilize the edges of the cave entrance by breaking back crumbling material to expose firm and stable ground. This should prevent pieces from possibly falling on workers inside the cave. The stabilized entrance is approximately twenty feet longer. The new cover accommodates the larger entrance and is being constructed on-site using pre-treated lumber with a joist and truss system.
Consultants also finished a draft profile view of the cave. The new profile shows the difficulty consultants and scientists experienced in exploring the cave with narrow passages between the cave chambers.
Williamson County expanded the fenced in area around the cave for safety. Cambria Drive will remain closed for several weeks while Williamson County works with the Texas Commission on Environmental Quality (TCEQ) on the remediation effort.
