Stone Harbor, NJ Coastal Erosion Rate
Shoreline change 0.5 miles southwest of Stone Harbor, NJ
0.5 miles southwest of Stone Harbor, NJ: USGS's transects didn't pick up a trend here that beats the survey's own uncertainty. That's the majority case nationally, and for this stretch specifically it means the coast is holding, not that the data failed to find anything.
What this reading actually covers
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 Stone Harbor, NJ. Centered near 39.04°N, 74.78°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.
Where this fits nationally
15 transects feed this segment's number; 100% of them individually measured retreat. USGS's confidence interval here is ±1.93 ft/yr. Taken at face value, this segment's raw -0.62 ft/yr reading would land it 257 of 1211 nationally - a number worth ignoring, since it's statistical noise rather than a real trend. Source: USGS Open-File Report 2010-1119. Rank 1179 nationally for growth belongs to Texas City, TX, 1316 miles from this stretch, measured at 2.85 ft/yr. Stone Harbor, NJ, 1.6 miles off, is the adjacent measured stretch, reading slight accretion (beach growing) at 0.73 ft/yr.
