Long Beach, NY Coastal Erosion Rate
What USGS measures 0.8 miles east of Long Beach, NY
Nothing alarming measured 0.8 miles east of Long Beach, 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
Long Beach, NY is the nearest named place, 0.8 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: 40.59, -73.65. The survey behind it runs to 2007-2009, in USGS's New England / Mid-Atlantic assessment, using the LRR method. Shoreline surveys aren't repeated every year, so this is the most recent long-term measurement USGS has published for this coast, not a live reading.
Where this fits nationally
85 transects feed this segment's number; 48% of them individually measured retreat. USGS's confidence interval here is ±0.95 ft/yr. The unadjusted figure here, 0.03 ft/yr, would place it 797 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. Rank 1162 nationally for growth belongs to Ocean City, NJ, 103 miles from this stretch, measured at 2.2 ft/yr. 2 miles away, Lido Beach, NY is the nearest other measured stretch: also no significant trend.
Not this whole stretch, just Long Beach itself: the Coastal Change Hazards Portal is USGS's own live version of this data.
