B. Use of other base flood and flood way data. When base flood elevation and flood way data has not been provided in accordance with § 146-5, Basis for establishing areas of special flood hazard, the Zoning Officer shall obtain, review and reasonably utilize any base flood elevation and flood way data available from a federal, state or other source, in order to administer § 146-14B(l), Specific standards, residential construction, and 146-14B(2), Specific standards, nonresidential construction.
