Data Sources:
Aerial Imagery: USDA, National Agriculture Imagery Program, 2004
Flood Zones and Elevations: FEMA Flood Insurance Rate Maps (Hancock Co., MS, [1983-1992]; Harrison Co., MS, [1984-2002];
Jackson Co., MS, [1984-1993]. Elevations converted from NGVD29 to NAVD88.
High Water Marks: FEMA (identified and surveyed Sept.-Oct., 2005)
Storm Track: NOAA National Weather Service
For more information on these advisory maps, please see www.fema.gov/hazards/floods/recoverydata/katrina_index.shtm

1 - Range estimated from surveyed, surge-only HWMs. Local wave effects (wave heights and runup) are not included in these elevations.
2 - Measured in feet relative to NAVD88.
3 - Post-Hurricane Katrina Advisory Base Flood Elevations (ABFEs) are based on updated statistical information to develop the estimated
1%-annual-chance (100-year) stillwater elevations (SWELs) plus estimated wave effects. For Harrison County, MS, the advisory SWEL is 18ft
for the Gulf Coast and 16ft for the back-bay areas. See equation below to calculate the AFBE with wave effects for a given site:
ABFE = Advisory SWEL + Wave Height,
where Wave Height = 1/2 Stillwater Flooding Depth (measured relative to the ground)
MAPS FOR ADVISORY PURPOSES ONLY - NOT FOR INSURANCE RATING PURPOSES
For insurance rating purposes, refer to the currently effective Flood Insurance Rate Map (FIRM), available from your local government or the FEMA Map Service Center (1-800-358-9616 http://msc.fema.gov).
