15.55.080 Base flood elevation.
A. The floodplain administrator shall obtain, review, and reasonably utilize any base flood elevation and floodway data available from a federal, state or other source, in order to administer this chapter.
B. The base flood elevations for the SFHAs of the city of Aberdeen shall be as follows:
1. In Zone AE and Zone AH on the flood insurance rate map, the base flood elevation shall be as shown in parentheses after the zone designation on the map.
2. In Zone AE where there is no elevation shown after the zone designation, the base flood elevation shall be the one (1) percent annual chance flood elevation as shown in the flood profile for the stream in the flood insurance study.
3. In Zone A where the flood insurance rate map and the flood insurance study do not provide a base flood elevation, the base flood elevation shall be determined by the city engineer using an approach approved by the Federal Emergency Management Agency for site-specific flood elevation determinations.
4. Where a flood rises higher than the base flood elevation as determined above, the base flood elevation shall be the elevation of the highest recorded flood level for that site.
