The flood that has a 1% chance of being equaled orexceeded in any given year. Base Flood Elevation (BFE)o The water surface elevation of the 1% annual chance flood.Attributes: FLD_ZONEo Flood zone designation used by County to designate a Special Flood Hazard Area (SFHA).o Zones: ASpecial Flood Hazard Area (SFHA) subject to inundation by the 1% annual chanceflood event. No base flood elevations determined. AESpecial Flood Hazard Area (SFHA) subject to inundation by the 1% annual chanceflood event. Base flood elevations (BFE) determined. XAreas determined to be outside the 0.2% annual chance floodplain. FLOODWAYo A \"Regulatory Floodway\" means the channel of a river or other watercourse and the adjacent land areas that must be reserved in order to discharge the base flood without cumulatively increasing the water surface elevation more than a designated height. Y \u2013 Yes; in floodway N \u2013 No; not in floodway", "summary": "The County Floodplain layer shows the boundary of the County managed floodplain.", "title": "Community_SFHA_Boundaries", "tags": [], "type": "", "typeKeywords": [], "thumbnail": "", "url": "", "minScale": "NaN", "maxScale": "NaN", "spatialReference": "", "accessInformation": "", "licenseInfo": "", "portalUrl": "" }
