The delineation of any of the identified flood-prone areas may be revised by the Board of Commissioners where more detailed studies have been conducted or information provided by a qualified agency or person documents the need for such revision. However, prior to any such change, approval must be obtained from the Federal Emergency Management Agency (FEMA).(Ord. 79-6. Passed 8-20-79; Ord. 2009-04. Passed 10-19-09.)
