(B) In the flood fringe and approximated floodplain districts, the development and/or use of land shall be permitted in accordance with the regulations of this chapter provided that all such uses, activities, and/or development shall be undertaken in strict compliance with the flood proofing and related provisions contained in the State Uniform Statewide Building Code, being 13 VAC 5-63, the general standards subchapter in this chapter (§§ 151.30 through 151.40) and the elevation and construction standards section (§ 151.31) and subdivision standards section (§ 151.32) in this chapter, and all other applicable codes and ordinances.
(C) Within the approximated floodplain areas, the applicant shall also delineate a floodway area based on the requirement that all existing and future development not increase the 100-year flood elevation more than one foot at any one point. The engineering principle–equal reduction of conveyance shall be used to make the determination of increased flood heights.
(D) Within the floodway area delineated by the applicant, the provisions of § 151.11 shall also apply.
