Mississippi Administrative Code › Title 33 - Public Health - Local Governments And Rural Water Systems Improvements Board › Part 208 - Flood Damage Prevention Regulation › Chapter 5 - Provisions for Flood Hazard Reduction › Rule 33-208-5.3 - Standards for Streams Without Base Flood Elevations and Floodways

Current through June 25, 2024
When base flood elevation data and floodway data are not
				  available in accordance with Part 208, Rule 3.1, in Special Flood Hazard Areas
and Community Flood Hazard Areas
without base flood elevation
				  data, new construction and substantial improvements shall be elevated or
				  floodproofed to elevations established by the community. The following
				  provisions in addition to the standards of Part 208, Rule 5.1 and the enclosure
				  standards of Part 208, Rule 5.2 (4) shall apply:
(1) Require that all new subdivision
				proposals and other proposed developments (including proposals for manufactured
				home parks and subdivisions) greater than five (5) lots or five (5) acres,
				whichever is lesser, include within such proposals base flood elevation
				data;
(2) The Floodplain
				Administrator shall obtain, review, and reasonably utilize any base flood
				elevation and floodway data available from a federal, state, or other source,
				in order to administer the provisions of Part 208, Rule 5. When such data are
				available, standards of Part 208, Rule 5.2, shall apply. If data is not
				available from Part 208, Rule 5.2 (1) or outside sources, then the following
				provisions shall apply.
(3) No
				encroachments, including fill material or other development, shall be located
				within a distance of the stream bank equal to five times the width of the
				stream at the top of the bank or twenty feet each side from the top of the
				bank, whichever is greater, unless certification by a registered professional
				engineer is provided demonstrating that such encroachment shall not result in
				any increase in flood levels during the occurrence of the base flood discharge.
				The enclosure standards of Part 208, Rule 5.2 (4) shall apply.
(4) Fill within the area of special flood
				hazard shall result in no net loss of natural floodplain storage. The volume of
				loss of floodwater storage due to filling in the special flood hazard area
				shall be offset by providing an equal volume of flood storage by excavation or
				other compensatory measures at or adjacent to the development site.
(5) Notify, in riverine situations, adjacent
				communities and the State Coordinating Office prior to any alteration or
				relocation of a watercourse and submit copies of such notifications to FEMA.
				Assure that the flood carrying capacity within the altered or relocated portion
				of any watercourse is maintained.
(6) Require that all manufactured homes be
				placed or installed using methods and practices which minimize flood damage.
				Manufactured homes must be elevated and anchored to resist flotation, collapse,
				or lateral movement. Dry stacked blocks (stacked without the use of mortar or
				cement to bond them together) are not allowed within the Special Flood Hazard
				Area.
