  Home > About > Long Range Planning  



Many government officials and planners agree that the year 2050 represents a reasonable planning horizon. Scientists’ best estimates are for an additional 1 to 2.5 feet of sea level rise by 2050.  Given that king tides often exceed 2 feet above MHHW, shallow or nuisance coastal flooding might be expected at elevations from 3 to 4 ft higher than at present.   Higher sea levels associated with possible storm surge (on top of expected SLR) can be visualized using the NJFloodMapper tool. However, caution is warranted in that extremely severe storms may potentially have surge levels higher than the 6 foot SLR mapped here.

As SuperStorm Sandy has demonstrated, storm surge topped 6 feet in many back-bay areas and was higher along the barrier islands and in Raritan Bay.
