Napeague, NY Coastal Erosion Rate
Is the coast eroding 0.7 miles east of Napeague, NY?
Nothing alarming measured 0.7 miles east of Napeague, NY: whatever shift USGS's transects picked up here is too small to call reliably one way or the other, which this site reports as "no significant trend" rather than forcing a direction.
What this reading actually covers
Napeague, NY is the nearest named place, 0.7 miles away, to a ~3.5-mile stretch of coast USGS has surveyed - the reading below covers that whole stretch, not a single property in it. Segment center: 41.00, -72.05. Survey years: 2007-2009, method LRR, from USGS's New England / Mid-Atlantic shoreline-change assessment. That's how current the data is here, real, but not a live feed, since a shoreline survey is a major undertaking, not an annual check-in.
What backs this reading up
Averaging 92 separate transects produced this segment's rate, with 10% individually reading as erosion, rather than relying on any single survey line. The published margin on this reading runs ±0.18 ft/yr. The unadjusted figure here, 0.11 ft/yr, would place it 857 of 1211 if ranked directly - but an unreliable rank isn't a useful one, which is exactly why "no significant trend" is the headline instead. Source: USGS Open-File Report 2010-1119. Ocean Shores, WA sits at national rank 1211 for growth (12.13 ft/yr), one reference point among the 1211 scored segments, 2574 miles from here. 2.7 miles away, Amagansett, NY is the nearest other measured stretch: also no significant trend.
