ST. LOUIS COUNTY, Mo. – Parts of mid-St. Louis County, from Ladue to Brentwood, saw rising floodwaters along Deer Creek.

The steady stream of rain Tuesday morning caused the creek to rise several inches as the morning wore on.

Over the course of the lunch hour in Brentwood, one could spot a volleyball, a basketball, branches, and debris move swiftly along the creek.

“I have seen it,” Nick Miriani, Advance Carpet One’s installation manager, said. “It’s come in the building before. It was like two years, and it came in the building and flooded and wiped out everything on the lower level. So, I’m hoping it doesn’t happen again. I think as long as we’re moving, that’s a good sign. Once that stops, we might be in trouble.”

Nick Mirianil is keeping an eye on the size of the rushing water in the rain, wondering if it will rise and cause flooding for this business.

Brentwood recently put in additional storm drains and retention ponds to help mitigate flash floods like this.

Meanwhile, in Rock Hill, it was dry inside the Trainwreck Saloon. But a few hundred feet away, a flooded truck displayed the scope of the flooded Forest Products Supply Co. parking lot.

“Usually, a couple hours in advance that we know the rain is coming, we try to get everything off the ground,” Dawson Carey, a Forest Products forklift operator, said. “Get it elevated; that way it doesn’t get washed away with all the rainwater.”

As forklifts head for higher ground, it’s debris clogging outlets along Deer Creek that is resulting in flooding at the lumber business.

Manchester Road, which has closed during flash flooding, reopened to drivers Tuesday afternoon.

“Oh, it’s just trash,” Miriani said. “Trash is the number one thing, and it blocks up the drains. Trash is the number one killer.”
