Atlantic City, NJ Coastal Erosion Rate
What USGS measures 1.4 miles south of Atlantic City, NJ
1.4 miles south of Atlantic City, NJ, the coast is advancing, not retreating, at a measured 1.38 feet a year, sediment accumulating faster than any erosion USGS recorded here. At that rate, the shoreline has gained roughly 13.8 feet over the last decade.
What "Atlantic City" means on this page
This is a roughly 3.5-mile stretch of coast, not one address or parcel - USGS's own transects run every few hundred feet, but that's finer than any one property needs, so this page reports the stretch nearest Atlantic City, NJ. Centered near 39.36°N, 74.45°W. USGS's New England / Mid-Atlantic assessment last surveyed this stretch through 2007-2009, computing the rate with its LRR method. Other US regions were surveyed in different years, sometimes decades apart, so this page states its own rather than implying one national vintage.
25 years at this rate
Holding the 1.38 ft/yr accretion rate 1.4 miles south of Atlantic City, NJ for 25 years would add roughly 35 feet of shoreline, again assuming nothing about the local sediment supply changes.
Where this fits nationally
96 transects feed this segment's number; 0% of them individually measured retreat. USGS's confidence interval here is ±0.77 ft/yr.
