Residents in a Williamson County neighborhood woke up Thursday morning to find a 20-foot-deep hole outside. Neighbors reported hearing what they thought was thunder at around 3 a.m. Thursday, then they called the utility district because the water went out. Ten homes in the area of Woods of Brushy Creek subdivision are without water due to a broken water line in the 8400 block of Cambria Drive, which is north of State Highway 45. Brushy Creek MUD says the roof of a cave collapsed at the intersection of Cambria Drive and Ephraim Road. The collapse broke the water line, which left nearly a dozen customers without water for most of the day. The utility district refers to this cave as a void and as a karst feature. The initial examination of the karst feature shows the limestone bed that forms the cave ceiling is thinner where the utility lines were installed.

There are caves all under Austin and that area of the state. Many Austin neighborhoods have greenbelts behind their homes which are scattered with covered holes or cave openings.
Thats gonna take a few yards of controlled density fill...
Thanks bgill. How long before it's blamed on global warming, climate change denial, and fracking?
Like the bat cave! Aren’t all caves “karst features”?
Gonna need a bigger dump truck....................
Yes there is insurance available for this, at least my insurance offers a rider.
You pay extra for it.
I dont bother with it. My house sits on glacial till. No caves and no mines to worry about.
This isn’t my fault.
“Like the bat cave! Arent all caves karst features?”
Holy hole, Batman!
I wonder why people are standing so close to this or one guy inside it. They just seem to be doing nothing, just staring at it...
There might be holes in the policy.
I am sure there are.
Put there by the insurance company.
Deep, dark and dank.
Where’s muh car?
I parked my Sherman tank out there. Wherezatnow?
You should get a ticket for tread damage to the roadway! lol
Lmao. That would be worth just to torque the hoa.
Gotta get the biggest USA flag they make and hang it from the barrel of the Sherman then.
Leave no board member’s arse unchafed!
Plan on baskets for the top section of casing and shoveling a short load of pea gravel to cement the top of the hole.
Do not try to cement up a cavern, you will go broke.
“The collapse broke the water line”
And I bet a leaky water line contributed to the collapse.
Looks like silicified coral weathering out on the left in there.
Whats really surprising is that the vibratory compactor didnt go through it when they were preparing the road subgrade!
