Layer: DPWES Dam Break Inundation Zones (0)

Name: DPWES Dam Break Inundation Zones

Display Field: DAM_NAME

Type: Feature Layer

Geometry Type: esriGeometryPolygon

Description: Dam breach inundation areas for state regulated dams within Fairfax County. Sunny Day – the failure of an impounding structure with the initial water level at the normal reservoir level, usually at the lowest ungated principal spillway elevation or the typical operating water level. PMF Overtopping – the failure of an impounding structure due to overtopping during a Probable Maximum Flood (PMF) event.Contact: DPWES GIS ServicesData Accessibility: For internal county usage only.
