Williamson County's plan to close the cave on Cambria Drive was approved by the Texas Commission on Environmental Quality was approved last month, and now we know how much it will cost.
The portion of the cave belonging to WilCo found in the Brushy Creek neighborhood in February will be filled in with concrete.
The county will decide whether or not to award the contract to mitigate the cave to Chasco Constructors of Round Rock, who submitted a bid of $530,425.
That cost includes rebuilding the street and sidewalk, reinstalling a water line, and the concrete and supports to fill in the cave.
In May, Williamson County Engineer Terron Evertson said it will take at least 200 trucks of concrete to fill the cave.
