  7. 7. Getting Ahead of the CurveGetting Ahead of the Curve In just 14 months, Hoboken was hit with 2In just 14 months, Hoboken was hit with 2 events greater the a 1% chance floodevents greater the a 1% chance flood Other environmental conditions that increaseOther environmental conditions that increase risk:risk:  Aging infrastructureAging infrastructure  High percentage of impervious coverHigh percentage of impervious cover  High residential densityHigh residential density  High percentage of at-risk populationsHigh percentage of at-risk populations  Limited mobility outside of mass transitLimited mobility outside of mass transit  Geographic and structural barriers to evacuationGeographic and structural barriers to evacuation FEMA Base Flood Elevation is not forwardFEMA Base Flood Elevation is not forward thinking enoughthinking enough
  8. 8. Getting Ahead of the CurveGetting Ahead of the Curve Hoboken chose to adopt the FEMA AdvisoryHoboken chose to adopt the FEMA Advisory Base Flood Elevation (ABFE) maps instead ofBase Flood Elevation (ABFE) maps instead of the working maps or Preliminary FIRMsthe working maps or Preliminary FIRMs because:because:  The Preliminary FIRMs lowered flood elevation 1 to 2’The Preliminary FIRMs lowered flood elevation 1 to 2’ compared to the ABFE Maps; andcompared to the ABFE Maps; and  Reduced the boundaries of the floodplainReduced the boundaries of the floodplain Added a Freeboard requirementAdded a Freeboard requirement  Incremental requirement from 1 to 3’ depending onIncremental requirement from 1 to 3’ depending on useuse Restricted the use of fill for all new constructionRestricted the use of fill for all new construction Added a definitive restriction on buildings onAdded a definitive restriction on buildings on piers and platforms in the V-zonepiers and platforms in the V-zone
