§ 19-314

Base flood elevation and floodway data

  • (a) Floodway data. In zones A, A1-30, and AE, along watercourses that have not had a regulatory floodway designated, the best available federal, state, local, or other floodway data shall be used to prohibit encroachments in floodways which would result in any increase in flood levels within the community during the occurrence of the base flood discharge.

  • (b) Base flood elevation data. Base flood elevation data is required for subdivision proposals or other developments greater than 50 lots or five acres, whichever is the lesser, within unnumbered A zones.

  • (c) Base flood elevations in A zones. In the absence of FEMA BFE data and floodway data, the best available federal, state, local, or other BFE or floodway data shall be used as the basis for elevating residential and nonresidential structures to or above the base flood level and for floodproofing nonresidential structures to or above the base flood level.
