What "West Hampton Dunes" means on this page
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 West Hampton Dunes, NY. Centered near 40.77°N, 72.75°W. 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.
25 years at this rate
If 0.6 ft/yr holds for the next 25 years, the coast 2.5 miles west of West Hampton Dunes, NY would retreat roughly 15 more feet, a projection, not a certainty: erosion rates shift with storms, sediment supply and any armoring built in the meantime.
