Point Lookout, NY Coastal Erosion Rate
What USGS measures 1.6 miles east of Point Lookout, NY
1.6 miles east of Point Lookout, NY, the coast is advancing, not retreating, at a measured 4.23 feet a year, sediment accumulating faster than any erosion USGS recorded here. At that rate, the shoreline has gained roughly 42.3 feet over the last decade.
What this reading actually covers
Point Lookout, NY is the nearest named place, 1.6 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, -73.55. 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.
What 4.23 ft/yr means over time
Holding the 4.23 ft/yr accretion rate 1.6 miles east of Point Lookout, NY for 25 years would add roughly 106 feet of shoreline, again assuming nothing about the local sediment supply changes.
Where this fits nationally
81 transects feed this segment's number; 0% of them individually measured retreat. USGS's confidence interval here is ±2.45 ft/yr. Sorted from fastest erosion to fastest growth across all 1211 measured segments nationally, this one lands at 1194. Source: USGS Open-File Report 2010-1119. Sanibel, FL sits at national rank 1176 for growth (2.71 ft/yr), one reference point among the 1211 scored segments, 1093 miles from here. 2.7 miles up the coast, Bellmore, NY shows the same lack of a significant trend.
