The delineation of any of the floodplain districts may be revised
by the Borough Council where natural or man-made changes have occurred
and/or more detailed studies conducted or undertaken by the United
States Army Corps of Engineers or other qualified agency or individual
documents the need or possibility for such change. However, prior
to any such change, approval must be obtained from the Federal Emergency
Management Agency. Additionally, as soon as practicable, but not later
than six months after the date such information becomes available,
a community shall notify the FEMA of the changes by submitting technical
or scientific data.
