How does storm water drain away from your area?
Water flows from land to the ocean in natural features such as rivers and streams. The movement of water may be enhanced, retained, or re-directed by various structures such as ditches, dams, and detention ponds.
The flood risk for any area is dependent on the capacity of the drainage features, detention ponds, and pumps. Flooding will occur when water rises faster than it can be drained away or retained by the control structures.
