Note: Include, where applicable, as part of the contingency plan, specific requirements in ss. NR 664.0227 and 664.0200.
Note: Where maps for the national flood insurance program produced by the federal insurance administration (FIA) of the federal emergency management agency are available, they will normally be determinative of whether a facility is located within or outside of the 100-year floodplain. However, where the FIA map excludes an area, usually areas of the floodplain less than 200 feet in width, these areas must be considered and a determination made as to whether they are in the 100-year floodplain. Where FIA maps are not available for a proposed facility location, the owner or operator must use equivalent mapping techniques to determine whether the facility is within the 100-year floodplain, and if so located, what the 100-year flood elevation would be.
Note: For large HWM facilities the department may allow the use of other scales on a case-by-case basis.
