New Flood Maps Show New DeSoto Flood Problems

(DeSoto County, MS) Charlie Thompson told us the day his street flooded, it came without warning.

“I was sitting in the house, it started running in my door and before I knew it, it put four feet of water in my house.”

The 2005 flood left almost every house on his street with significant flood damage.

That’s why DeSoto County Supervisors took action Monday to identify problem flood areas, and limit the way they’re developed.

Maps from the last seven years show the problem.

In 2007, DeSoto County had relatively few flood problem areas, but brand new maps show a 100-year flood potential along Rocky Creek through the heart of Southaven.

Flooding isn’t just a problem for low-lying rural areas.

Runoff from parking lots and cement gutters send more water downstream faster, and all that water has to go somewhere.

Supervisor Harvey Lee says, since the water doesn’t have a chance to soak in, it runs off big paved areas and collects anywhere it can.

“We’re looking at a lot of curb and gutters when you change the direction of the water then you’re gonna have problems.”

That’s why many big developments have to have big retention ponds to hold that storm water.

Thompson’s neighborhood now has three after the 2005 flood.

“They took action. They got it taken care of. We haven’t had no more problem.”

He hopes the new maps and some new development rules will keep the problem from happening in other areas.
