(A) In their interpretation and application, the provisions of this chapter shall be held to be minimum requirements and shall be liberally construed in favor of the City Council and shall not be deemed a limitation or repeal of any other powers granted by state statutes.
(B) The boundaries of the zoning districts shall be determined by scaling distances on the official zoning map. Where interpretation is needed as to the exact location of the boundaries of the district as shown on the official zoning map, as for example where there appears to be a conflict between a mapped boundary and actual field conditions and there is a formal appeal of the decision of the Zoning Administrator, the Board of Adjustment shall make the necessary interpretation. All decisions will be based on elevations on the regional (100-year) Flood profile, the ground elevations that existed on the site at the time the city adopted its initial Floodplain ordinance or on the date of the first national Flood insurance program map showing the area within the 100-year Floodplain if earlier, and other available technical data. Persons contesting the location of the district boundaries shall be given a reasonable opportunity to present their case to the Board of Adjustment and to submit technical evidence.
