INITIAL REVIEW COMMENTS ON FEMA STUDY

• The only encroachment into the Sespe Levee
  freeboard is upstream Hwy 126 bridge
• FEMA hydraulic model has Hwy 126 bridge 2.5 feet
  to low, 12 bridge piers rather than 11 and piers
  3 thick instead of 15.
• It is possible once FEMA makes corrections Sespe
  Creek Flood Plain and Floodway may be eliminate
  on this draft of the DFIRM
