The Pinehills, MA Coastal Erosion Rate
What USGS measures 2.3 miles east of The Pinehills, MA
2.3 miles east of The Pinehills, MA: USGS's transects didn't pick up a trend here that beats the survey's own uncertainty. That's the majority case nationally, and for this stretch specifically it means the coast is holding, not that the data failed to find anything.
What this reading actually covers
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 The Pinehills, MA. Centered near 41.90°N, 70.55°W. 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
This reading comes from 138 individual transects averaged together, 89% of which measured erosion rather than growth. Uncertainty on this specific number: 0.17 ft/yr either side. Taken at face value, this segment's raw -0.11 ft/yr reading would land it 630 of 1211 nationally - a number worth ignoring, since it's statistical noise rather than a real trend. Source: USGS Open-File Report 2010-1119. For scale: Ilwaco, WA, 2622 miles away, ranks 1198 of 1211 nationally for growth, 5.01 ft/yr. 2 miles away, The Pinehills, MA is the nearest other measured stretch: also no significant trend.
Not this whole stretch, just The Pinehills itself: the Coastal Change Hazards Portal is USGS's own live version of this data.
