<br />The various floodplain districts shall include special flood hazard areas. The basis for the delineation of these districts shall be the Flood Insurance
<br />Study (FIS) and the Flood Insurance Rate Maps for the City of Martinsville prepared by the Federal Emergency Management Agency, Federal
<br />Insurance Administration, dated 9/26/08, as amended.
<br />I. The Floodway District is delineated, for purposes of this ordinance, using the criterion that certain areas within the floodplain must be capable of
<br />carrying the waters of the one hundred (lOO)-year flood without increasing the water surface elevation of that flood more than one (I) foot at any
<br />point. The areas included in this District are specifically defined in Table 2 of the above-referenced Flood Insurance Study and shown on the
<br />accompanying Flood Boundary and Floodway Map or Flood Insurance Rate Map.
<br />2. The Special Floodplain District shall be those areas identified as either an AE Zone or A 1-30 zone on the maps aecoll1lanying the Flood Insurance
<br />Study for which one hundred (lOO)-year flood elevations have been provided but for which no floodway has been delineated.
<br />
<br />3. The Approximated Floodplain District shall be those areas identified as an A or A99 Zone on the maps accompanying the Flood Insurance Study.
<br />In these zones, no detailed flood profiles or elevations are provided, but the one hundred (I OO)-year floodplain boundary has been approximated.
<br />B. Overlay Concept
<br />I. The Floodplain Districts described above shall be overlays to the existing underlying districts as shown on the Official Zoning Ordinance Map,
<br />and as such, the provisions for the floodplain districts shall serve as a supplement to the underlying district provisions.
<br />2. If there is any conflict between the provisions or requirements of the Floodplain Districts and those of any underlying district, the more restrictive
<br />provisions and/or thosc pertaining to the floodplain districts shall apply.
<br />3. In the event any provision concerning a Floodplain District is declared inapplicable as a result of any legislative or administrative actions or
<br />judicial decision, the basic underlying provisions shall remain applicable.
<br />Section 3.2 - Official Zoning Map
<br />The boundaries of the Special Flood Hazard Area and Floodplain Districts are established as shown on the Flood Boundary and Floodway Map and/or Flood
<br />Insurance Rate Map which is declared to be a part of this ordinance and which shall be kept on tile at the City of Martinsville offices.
<br />Section 3.3 - District Boundary Changes
<br />The delineation of any cf the Floodplain Districts may be revised by the City of Martinsville where natural or man-made changes have occurred and/or where more
<br />detailed studies have been conducted or undertaken by the U. S. ArnlY Corps of Engineers or other qualified agency, or an individual documents the need for such
<br />change. However, prior to any such change, approval must be obtained from the Federal Insurance Administration.
<br />Section 3.4 - Interpretatioo of District Boundaries
<br />Initial interpretations of the bowldaries of the Floodplain Districts shall bc made by the Zoning Officer Should a dispute arise concerning the boundaries of any of
<br />the Districts, the Board of Zoning Appeals shall make the necessary determnation. The person questicning or contesting the location of the District boundary shall
<br />be given a reasomble opportunity to present his case to the Board and to submit his own technical evidence ifhe so desires.
