WHY ARE THE NEW ADVISORY BASE FLOOD ELEVATIONS LOWER THAN HURRICANES KATRINA AND RITA FLOOD ELEVATIONS?
The Advisory Base Flood Elevations are based on the 1-percent-annual-chance flood event, or 100-year flood. The Advisory Base Flood Elevations are lower than Hurricanes Katrina and Rita flood elevations because these were more extreme events than the base flood event. The elevations of the 1-percent- annual-chance flood are the Federal standard for floodplain management. Buildings constructed to this standard are still vulnerable to the effects of larger events like Hurricanes Katrina and Rita.
