To slow the flow of silt, ADEM hurries around handing out warnings and fines to cover the cost of required improvements, but developers usually shrug their shoulders and pay the fines, blaming runoff problems on Mother Nature. According to residents behind the Schillinger Road Winn Dixie, Second and Milkhouse Creeks used to be six to eight feet deep. Now they say dogs have to roll over to get wet. Results Both surface and belowground drainage is used to control stormwater runoff. They also divert natural tributaries that once existed on these sites.
Detention basins control storm drainage by intercepting runoff and detaining it.
The inflow is faster than the outflow. A retention pond traps stormwater to a certain level where a drainpipe exists. The water infiltrates into the ground and flows out the pipe into a drainpipe, which may lead to a nearby ditch if the water level is high. The detention basin has a slope on the north side of 27 ft per 90 ft. This is a pretty large basin.
