(A) All developments within areas of special flood hazard as delineated on the official national flood insurance program’s latest or current flood insurance rate maps, or as determined by the City Engineer, shall comply with the following requirements:
(1) Establish to the satisfaction of the city the elevation of the 100-year flood.
(2) Set the minimum finished floor elevation to at least 1.5 feet above the 100-year flood elevation. It is the responsibility of the developer to insure that all finished floor elevations are set to 1.5 feet above the 100-year flood elevation.
(3) All fill within the 100-year floodplain shall be compensated by creation of stormwater storage of an equal or greater volume, credited above the seasonal high water table. Such compensatory storage shall
be located within or directly connected to the 100-year floodplain so that the flood waters can move freely into and out of the compensation area. Stormwater retention and detention volumes below the seasonal high water table shall not be used to compensate for the placement of fill within the 100-year floodplain.
(B) All developments within river line flood hazard areas shall be designed to maintain the flood carrying capacity of the floodway such that the base flood elevations are not increased, either upstream or downstream.
