A. When the Federal Emergency Management Agency has designated special flood hazard areas on the community's Flood Insurance Rate Map (FIRM) but has neither produced water surface elevation data nor identified a floodway, the Local Flood Plain Administrator shall attempt to obtain, review and reasonably utilize any base flood elevation and floodway data available from a Federal, State or other source, including data developed pursuant to subsection 10-1-13H of this Chapter, as criteria for requiring new construction, substantial improvements or other proposed development meets the requirements of this Chapter.
B. When base flood elevations are not available, the Local Flood Plain Administrator may use flood information from any other authoritative source, such as historical data, to establish flood elevations within the special flood hazard areas. This information shall be submitted to the City for adoption. (Ord. 99-02, 7-6-1999)
