Subject: Implementation of Additional Flood Inundation Maps

On Monday, October 17, 2016, the National Weather Service (NWS)
implemented five additional flood inundation map libraries across
northern New Jersey. In all, thirty-one flood inundation map
libraries now exist across New Jerseys river basins. Each of them
can be viewed on the Advanced Hydrologic Prediction Service (AHPS)
web portal.

Inundation maps provide information on the spatial extent and depth
of flood waters in the vicinity of both NWS 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.

Flood inundation maps are now available for the following gauges and
municipalities.


Gauge                            Municipalities

Assunpink at Trenton            Hamilton Twp., City of Trenton

Rahway River at Springfield     Cranford Twp., Kenilworth Twp.,
                                Springfield Twp., Union Twp.,
                                Town of Westfield

Ramapo River at Oakland         Borough of Oakland

Ramapo River at Pompton Lakes   Borough of Oakland, Pequannock Twp.,
                                Borough of Pompton Lakes, Borough of
                                Riverdale, Wayne Twp.

Raritan River at Manville       Bridgewater Twp., Franklin Twp.,
                                Hillsborough Twp., Borough of Manville,
                                Borough of Somerville


Each inundation library is associated with a United States
Geological Survey (USGS) river gauge 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:

https://water.weather.gov/ahps

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

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

A users guide for the flood inundation map web interface is
available at:

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

These new 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.
