WHAT ARE THE HURRICANE KATRINA SURGE INUNDATION AND ADVISORY BASE FLOOD ELEVATION MAPS?
The Hurricane Katrina Surge Inundation and Advisory Base Flood Elevation Maps (also referred to as “Katrina Recovery Maps”) consist of a series of 228 aerial photographs that show several kinds of coastal flood-related data for areas along the Mississippi coastline. They were developed by the Federal Emergency Management Agency (FEMA) in cooperation with other Federal and state agencies. FEMA used pre-existing data combined with information obtained immediately after Hurricane Katrina. The new information includes high water marks left behind by Hurricane Katrina, an estimate of Hurricane Katrina’s coastal flood limits, and advisory 1%-annual-chance (100-year) flood elevations that can be used during reconstruction.
