in effect1150.15 - Use of other base flood elevation and floodway data.
Special flood hazard areas where base flood elevation data have not been provided by the Federal Emergency Management Agency are designated as Zone A on the Flood Insurance Rate Map. Within these areas, the Director shall obtain, review, and reasonably utilize any base flood elevation and floodway data available from a federal, state, or other source, including data obtained under other provisions of this chapter; and where floodway data are available, administer all of the provisions of the Columbus City Codes.
All activities, development, and/or uses proposed in special flood hazard areas where the flood insurance study provides base flood elevation data as set forth in this chapter, but no floodways have been designated, shall be reviewed and approved before a Special Flood Hazard Area Development and Use Permit is issued. The certificate shall only be issued after it is demonstrated that the cumulative effect of any proposal, combined with all other existing and anticipated activities, development, and/or uses shall not increase the water surface elevation of the base flood more than one-half (½) foot at any point.
