ST. TAMMANY PARISH, LA (WVUE) - One year ago this week, more than 700 structures flooded in St. Tammany Parish.
Peyton Schilling remembers watching in horror as the water rose on his front lawn.
"I look out the window and saw water up to the mailbox and said, what is happening?" Schilling said.
It kept coming for four hours in the Tallow Creek subdivision, flooding a half dozen homes and forcing dozens of evacuations.
"I said, OK let's go ahead and get out of here just in case, seeing other houses down the street already starting to flood," said Delia Schilling.
Tallow Creek residents say what happened was an example of a drainage system working in reverse. The water in a retention pond filled up, forcing water into a culvert. The water then backed up through the culverts and came out through the catch basins throughout the neighborhood, flooding several homes.
"A lot of people didn't have flood insurance a lot of people," said Delia.
It was a rainfall that dumped nearly 2 feet of water in some portions of the state, flooding Greg Shelton's office in the Boston Commons retail park in Covington.
"The water got up about 2 feet inside the stucco. We had to redo all the drywall," said Shelton.
Ed Porche also works in Boston Commons. He managed to safely lift most of his files above the 3-foot watermark in an office he never thought would flood.
"I remember coming across the bridge and there's all kinds of debris up against the bridge," said Porche.
The rain brought the Bogue Falaya River 6 feet above flood stage, flooding homes and stores in the Lee Lane shopping area.
"It would be nice if we could do something to prevent it from happening again," said shop owner Michelle Stegall.
Parish spokesman Ron Simpson said the parish is studying the Tallow Creek basin to determine what, if anything, should be done to mitigate flooding problems in the future. Results of that study are expected soon.
