(A) The areas of special flood hazard identified by the Federal Insurance Administration in a scientific and engineering report entitled “The Flood Insurance Study (FIS) for Washington County and Incorporated Areas”, dated 10-19-2018, with accompanying Flood Insurance Maps are hereby adopted by reference and declared to be a part of this chapter. The Flood Insurance Study is on file at the City Hall and can also be obtained through the county. The city shall utilize all authoritative information available in determining the location of special flood hazard areas.
(B) In areas where a regulatory floodway has not been designated, no new construction, substantial improvements or other development (including fill) shall be permitted within Zones A1-30 and AE on the community’s FIRM, unless it is demonstrated that the cumulative effect of the proposed development, when combined with all other existing and anticipated development, will not increase the water surface elevation of the base flood more than one foot at any point within the community.
