Shallow flooding means a depth of less than 3 feet.
Sample 1Sample 2Sample 3
Shallow flooding means flooding with an average depth of less than three feet in areas where a clearly defined channel does not exist.
Sample 1Sample 2
Shallow flooding means areas where the base flood depth is between one to three feet, a clearly defined channel does not exist and the path of flooding is not determinable. Areas of shallow flooding are identified on the F.I.R.M. maps as zone "A- O".
