Part of the flood mitigation effort involves bringing in Bladder Dams. Basically these are long plastic tubes filled with water that act as barriers to the flood waters.
The deployment was along 1st (excuse me – Riverside) up to 72nd and then up 72nd to around 4th.
This didn’t sit well with the owner of the Hardware Store – understandably so because that put her store on the wrong side of the dam. People asked why the couldn’t be deployed along the lane way behind the store?
There is a simple reason and you’ll see it in the video below. The tubes need to be anchored or the flood water will simply roll or push them back and they’ll become fouled on obstacles, tear and fail. So they are anchored via straps that are held in place by large screws that can be drilled into asphalt but not so easily into concrete.
I took some video the the deployment. These fill them in sections and you get to see one section being filled and inflated.
