Stormwater Management is the controlling of stormwater through a variety of control structures. Drainage facilities are studied and constructed based on hydraulic studies, all to minimize flooding and erosion.  Detention facilities and retainage ponds are created near development to capture storm that has entered the underground drainage conveyance system. These ponds store the water for 24 to 48 hours and release same to minimize or eliminate flooding. The release of water from these man-made ponds can be regulated over a set time period, depending upon topography, development, and rainfall totals for a particular region of drainage basin.
