Name: Floodplain (DPIE)

Display Field: FLOOD

Type: Feature Layer

Geometry Type: esriGeometryPolygon

Description: The Floodplain_DOE_Partial_Py feature class is a portion of the floodplain delineation based on the watershed studies using ultimate land-use conditions and therefore usually extends beyond the FEMA floodplain which is based on existing land-use conditions. The studies were either conducted by or for the Storm Water Management Technical Group, originally a multi-agency technical group (doing hydrologic and hydraulic watershed studies). Salman (DPIE) compares floodplains (FEMA , SWMTG or other private study) and determines which one is higher and therefore governs which becomes the regulatory floodplain. This can vary within a watershed, for any specific case, the final regulatory floodplain determination lies with DPIE. This feature class is incomplete, missing several floodplain studies and is intended for internal analysis only and is not to be distributed.For more information, contact Michael J.
