Subject:    Updated Flood Inundation Maps across the Passaic Basin

Benefiting from new U.S. Army Corps of Engineers (USACE) modeling
techniques, the National Weather Service (NWS) was able to update seven
flood inundation map libraries across northern New Jersey.

Incorporating the new modeling, the length of the seven inundation
libraries, or reach, was expanded. The updated inundation libraries are
now on the Advanced Hydrologic Prediction Service (AHPS) web portal.

In all, thirty-five flood inundation map libraries exist across New
Jersey's river basins. Each of them can be viewed on AHPS.

Inundation maps provide information on the spatial extent and depth of
flood waters in the vicinity of both river forecast and non-forecast
points. Users are able to display flood inundation maps for various
levels ranging from minor flooding through and/or above the largest
observed flood.

These are the seven updated flood inundation map libraries and the
communities they serve.

Each inundation library is associated with a United States Geological
Survey (USGS) river gage and/or NWS forecast point.

Flood inundation maps, combined with river observations and NWS
forecasts, enhance the communication of flood risk, provide users with
additional information to better mitigate the impacts of flooding, and
build more resilient communities.

These flood inundation maps and associated geospatial data (shapefiles)
can be accessed through the AHPS portal:

http://water.weather.gov/ahps

A complete list of flood inundation map locations is online at:

http://water.weather.gov/ahps/inundation.php

A user's guide for the flood inundation map web interface is available
at:

http://water.weather.gov/ahps/inundation_mapping_user_guide.pdf

These inundation maps were developed in partnership with the New Jersey
Department of Environmental Protection, the New York and Philadelphia
Districts of the U.S. Army Corps of Engineers, the New Jersey U.S.
Geological Survey, and made online in cooperation with the Federal
Emergency Management Agency Region II.
