11. Future Tool Enhancements

12. 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

13. 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
