11 News is hearing about new evidence of flooding concerns from the Waldo Canyon fire.

What once was part of the hillside behind Eric Supancic's house is now a muddy black puddle in a small retaining pond just beyond his backyard. Rain at the beginning of the week sent a mudslide rolling through the hills behind homes on Coldwater Drive.

“It was that big, heavy storm on Monday that came through and gave us a wake-up call,” Eric said. At the worst of the storm almost 4 feet of soot and mud reportedly ran through the gullies behind the houses.

Other neighbors say it’s been 13 years since enough water came through to exceed the banks of that pond. Their concern now is what will happen when rain falls on the burn scar.

“I don't know if it’s going to be mud or just water, or just how much can be collected from above,” said Eric.

Eric says the Fire Department has been by twice to assess the mudflow into the retaining pond since Monday.

He doesn't know what can be done to prevent mudslides on the hillside beyond his fence. As for his home, Eric is bracing for the next storm.

“I got some sandbags ordered,” he said. “I am going to install those.”

A number of families including Eric’s are looking into flood insurance if they haven't already purchased it.
