(A) The delineation of the identified special flood hazard areas may be revised by the town where natural or human-made changes have occurred or more detailed studies conducted or undertaken by the U.S. Army Corps of Engineers, a river basin commission or other qualified agencies or individuals document the necessity for such changes. However, prior to any such change, approval must be obtained from the Federal Emergency Management Agency (FEMA).
(B) The town’s base flood elevations may increase or decrease resulting from physical changes affecting flooding conditions. As soon as practicable, but not later than six months after the date such information becomes available, the town shall notify the NFIP Administrator of the changes by submitting technical or scientific data.
(C) The town may identify and regulate new local flood hazard or ponding areas. These areas may be delineated on a local flood hazard map using the best available topographic data and locally derived information, such as floods of record, historic high water marks or approximate study methodologies.
