As you can see, the post-development increased the Peak runoff rate to 79 cfs from 36 cfs in its natural state. Our goal now is to design a detention pond that will produce an outflow hydrograph that looks similar to the pre-developed (red) hydrograph for the 2, 10 and 100-year events. Design Your Detention PondA lot of times retention and detention ponds are built near each other. The detention pond will hold the water up first and help prevent flooding. Water will then slowly drain out into the retention pond where it is held. These ponds also can assist with pollution removal. During periods of heavy rain, the ponds slow water movement.Subcategory: Retention/Detention Description Stormwater wetlands (or constructed wetlands) are structural post-construction stormwater controls similar to wet ponds (see the Wet Ponds fact sheet) whose design incorporates shallow zones and vegetation.
