NJOEM and NWS to Complete Inundation Mapping for Passaic River

The Great Falls after inches (0 mm) of rain dr...Image via WikipediaWhile I strive to maintain a balance of objectivity and common sense at Pequannock News, I was very surprised and dismayed to learn that complete and up to date inundation maps for flooding along the Passaic River do not exist.  It is very difficult to determine evacuation and relief operations without a comprehensive study of where the water flows and when.

Point #11 from Christie's 15 Point Flood Plan appears to be just this: creating comprehensive and up to date inundation maps for the areas along the Passaic River.

Progress is as follows (from the NJ DEP Passaic River Flood Committee progress report):


March 11, 2011
• The DEP met with USGS to work on a priority work plan based upon updated H and H. A proposal is expected within a month.
March 22, 2011
• Funds for JBOC were transferred on March 8.
• DEP met with USGS and a proposal will be drafted by the end of March.
• The next step is to sign a joint funding agreement with USGS.
June 1, 2011
• $500,000 has been provided for inundation mapping preparation and risk assessment at USGS gage and NWS flood forecast locations.
• DEP has prioritized the existing 30 USGS gages (which include 12 AHPS flood forecast points).
July 1, 2011
• DEP has developed a plan for preparing the inundation mapping for the appropriate gage locations.
• DEP has signed a joint funding agreement with USGS to start the process.
August 4, 2011
• DEP has signed a joint funding agreement with USGS to start the process, at the same time requesting that the following gage inundation map projects be started:  Peckman River at Little Falls, NJ (01389550), Saddle River at Ridgewood, NJ (01390500), Hohokus Brook at Ho-Ho-Kus, NJ (01391000) and Saddle River at Upper Saddle River, NJ (01390450).
September 14, 2011
• DEP and the Army Corps are awarded a grant under the  Silver Jacket program to develop inundation maps for four flood gage
