Projected Impact of Relative Sea Level Rise on
the National Flood Insurance Program

• Congress Authorized Study Nov. 1989
• FEMA Given One Year to Produce Report
• Report Dated October 1991
• You do the Math

Report Contents

• Studied Impacts from 1 ft. to 3 ft. Year 2100
• Inundated Land Area for U.S. during Base Flood
  would go from 19,500 mi2 to 23,000 mi2 for 1 ft.
  Rise and 27,000 mi2 for 3 ft. Rise
• 2.7 Million Homes Impacted Now (that would be
  approx. 1989). Impact additional 3 million homes
