Located within Special Flood Hazard Areas are small streams where no base flood data has been provided. The following provisions apply within such areas:
(A) No encroachments, including fill, new construction, substantial improvements, or new development, shall be permitted within a distance of the stream bank equal to five (5) times the width of the stream at the top of the bank or twenty (20) feet each side from the top of the bank, whichever is greater, unless a special use is approved or the use is permitted.

Standards for Streams without Established Base Flood Elevations
(B) In cases where the streams lacking base flood data are USGS or County Soils Map streams, then the limitations upon encroachments shall apply to the entire area within the associated UTBs, or an area five (5) times the width of the stream at the top of the bank, whichever is greater.
(C) If paragraph (A) above is satisfied, and base flood elevation data is available from other sources, all new construction and substantial improvements within such areas shall comply with all applicable flood hazard ordinance provisions of this Section and shall be elevated or flood-proofed in accordance with elevations established under Section 14.7.2. When base flood elevation data is not available from a federal, state, or other source, the lowest floor, including basement, shall be elevated to or above the regulatory flood protection elevation as defined in Chapter 12.
