| Maps showing the extent and magnitude
of Hurricane Katrina’s surge, as well as information on advisory
flood data, were created for areas in southeastern Louisiana parishes
that were most severely impacted by coastal flooding. These maps
show high water marks surveyed after the storm, an inundation limit
developed from these surveyed points, and FEMA’s Advisory
Base Flood Elevations (ABFEs). To access the Katrina Recovery Maps
for each Louisiana parish, click on the links below.

Maps showing the extent and magnitude of Hurricane
Ritaís
surge, as well as information on advisory flood data, were created for
areas in southern Louisiana parishes that were most severely impacted by
coastal flooding. These maps, referred to as ìRita Recovery Maps,î show
high water marks surveyed after the storm, an inundation limit developed
from these surveyed points, and FEMAís Advisory Base Flood Elevations
(ABFEs). To access the Rita Recovery Maps for each Louisiana parish included
in this project, click on the links or map below.

Rita/Katrina Recovery Maps are for advisory purposes only; they
do not supersede effective Flood Insurance Rate Maps (FIRMs) for insurance
rating purposes. The Hurricane Katrina-related data presented are preliminary
and subject to update as additional data become available.
In addition, FEMA has produced index maps for each parish. These maps
show the detailed Katrina Recovery Map paneling scheme, the Hurricane Katrina
preliminary High Water Mark (HWM) locations, the Katrina surge inundation
limit, and other basic map information (e.g., roads, corporate limits)
to help map users locate recovery maps for particular areas of interest.
The index map for each parish can be found on its respective mapping home
page, which can be accessed through the links above.
 FEMA
has also produced the first of several regional overview maps concerning
the parishes impacted by Hurricane Katrina. This first map (PDF 0.8MB)
covers the first parishes for which detailed Katrina Recovery Maps were
published: St. Tammany, Tangipahoa, St. John the Baptist (north of the
Mississippi River), and St. Charles (north of the Mississippi River). The
overview map shows the paneling scheme for the recovery maps, the Hurricane
Katrina preliminary HWM locations, the Katrina surge inundation limit,
and Katrina storm surge elevation contours. The latter feature is based
on an assessment of the general surge trends interpreted from the surveyed
HWMs, engineering judgment concerning general surge behavior in coastal
areas, and a comparison against numerical surge forecasts (e.g., SLOSH
model runs) prepared by the National Oceanic and Atmospheric Administration’s
Tropical Prediction Center. |
