A.Â
Any modification, alteration, reconstruction or improvement of any
kind to an existing structure, to an extent or amount of 50% or more
of its market value, shall constitute a substantial improvement and
shall be undertaken only in full compliance with the provisions of
this chapter, including the obtaining of a floodplain permit or special
permit, as necessary.
B.Â
No expansion or enlargement of an existing structure shall be allowed
within any floodway area that would cause any increase in the elevation
of the one-hundred-year flood.
