b. recreation consistent with the requirements of the floodplain;
c. Fish and wildlife management; and
d. Open space.
(2) Development within floodplains shall not have adverse impacts upon adjoining properties.
(3) All development within floodplains shall require a building permit, unless the development consists solely of activities which are excluded from the meaning of the term "development."
(4) Development requiring a building permit shall not cause a net loss in the flood storage capacity of the floodplain. The provisions of section 90-148(3), relating to floodplain storage and conveyance, shall also apply.
(5) floodplain elevations shall be determined utilizing the best available data, which includes firm maps and the flood insurance studies for the county and unincorporated areas, dated April 3, 1989, prepared by FEMA.
(6) Development within the 100- to 25-year floodplain shall not negatively impact other property or the receiving surface water body quality.
