A percentage of the overflow would empty into a drain that leads into city storm sewers. The second pond is also covered with grass. It should be noted that this pond appears to be a new addition. One can tell the sod has just been planted. This pond has more water than the first, approximately two to three feet.
Land slopes away from the pond, inhibiting direct runoff flow.
Runoff enters this pond directly from storm drains. These drains are placed periodically throughout the Wal-Mart driveway. Upon comparing the drainage area to the volume of the ponds, it was determined that this site could withstand a five year flood event. However, fifty and one hundred year flood cycle events would result in pond overflow. The second research site was located at a Citgo gas station at the corner of Old Shell and Schillenger.
