Future Plans Future Plans Flood depth / flood surface elevation Flood depth / flood surface elevation Migration to ArcGIS Server Migration to ArcGIS Server Continued incorporation of new DFIRM data Continued incorporation of new DFIRM data
Future Tool Enhancements
Limitations of Scale ► FEMA DFIRMs moving towards an entirely digital product ► Where do we draw the line with digital data? ► FEMA traditional guidelines (min. floodplain width) vs. digital mapping capabilities (detail) ► What should be considered as significant flooding? ► Terrain considerations ► Velocity and depth considerations
WV Disaster Recovery Mapping ► Enhanced Zone A FP development for streams >1 sq mile ► Revised effective Zone A FPs ► Six WV Counties ► 1700 steam miles ► Potential Future Counties Fayette, Greenbrier, Mercer, Raleigh, Kanawha
