For National Flood Insurance Program purposes, shallow flooding conditions are defined as flooding that is limited to 3.0 feet or less in depth where no defined channel exists. Sheet Runoff-The broad, relatively unconfined downslope movement of water across sloping terrain that results from many sources, including intense rainfall and! or snowmelt, overflow from a channel that crosses a drainage divide, and overflow from a perched channel onto deltas or plains of lower elevation. Sheet runoff is typical in areas of low topographic relief and poorly established drainage systems. Special Conversion-An action taken by FEMA to convert a community to the Regular Phase of the National Flood Insurance Program without preparing a FIRM with detailed flood risk zones. The exact action taken depends on whether FEMA detennines the community is "non-floodprone" or "minimally floodprone." Special Conversion Recommendation Report (SCRR) -A report, prepared by the FEMA Regional Office and submitted to FEMA HQ, that documents the reasons a community should be converted to the Regular Phase of the National Flood Insurance Program without a detailed engineering study being perfonned and recommends a specific conversion action. Special Flood Hazard Area (SFHA}-The area delineated on a National Flood Insurance Program map as being subject to inundation by the base flood. SFHAs are determined using statistical analyses of records of riverflow, stonn tides, and rainfall; infonnation obtained through consultation with a community; floodplain topographic surveys; and hydrologic and hydraulic analyses. Special Problem Report (SPR) -A report, prepared by the Flood Hazard Mapping Partner that is perfonning an engineering study or other mapping activity, that documents special problems or issues encountered during the performance of the work. Stage-The height of a water surface above an established datum plane. Standard Interchange Format (SIF)--A commonly used fonnat for the exchange of alphanumeric data. State-Any State, the District of Columbia, the territories and possessions of the United States, the Commonwealth of Puerto Rico, and the Trust Territory of the Pacific Islands.
