Description

This polygon layer defines the flood zones for determining whether a property or structure in question lies within a Special Flood Hazard Area (SFHA) as defined by the Federal Emergency Management Agency (FEMA).  A SFHA is also known as the 100-year floodplain.  It is more precisely defined as the floodplain associated with a flood that has a 1-percent-annual chance of being equaled or exceeded in any given year.  Therefore the SFHA is not a flood event that happens once in a hundred years, rather a flood event that has a 1-percent chance of occurring every year.FEATURE CLASS: GIS.FloodZone2008FEATURE DATASET: GIS.FloodPlainDEPARTMENT RESPONSIBLE: Public WorksDATA SOURCE: FEMA Flood Insurance Rate Maps (FIRM)MAINTENANCE: Updated on a continuous basisREFERENCE: http://www.fema.gov/flood-zonesREALTED DATA: None
