Lido Beach, NY Coastal Erosion Rate
Shoreline change 0.3 miles west of Lido Beach, NY
Nothing alarming measured 0.3 miles west of Lido 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
Lido Beach, NY is the nearest named place, 0.3 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, -73.61. 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.
How solid is this number
Averaging 46 separate transects produced this segment's rate, with 48% individually reading as erosion, rather than relying on any single survey line. The published margin on this reading runs ±2.25 ft/yr. The unadjusted figure here, 0.01 ft/yr, would place it 780 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. Costa Mesa, CA sits at national rank 1140 for growth (1.48 ft/yr), one reference point among the 1211 scored segments, 2464 miles from here. 2 miles up the coast, Long Beach, NY shows the same lack of a significant trend.
