The Pinehills, MA Coastal Erosion Rate

Shoreline change 2.7 miles northeast of The Pinehills, MA

No significant trend

2.7 miles northeast 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 41.93°N, 70.56°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.

What backs this reading up

Averaging 34 separate transects produced this segment's rate, with 71% individually reading as erosion, rather than relying on any single survey line. USGS's confidence interval here is ±0.21 ft/yr. Taken at face value, this segment's raw -0.13 ft/yr reading would land it 594 of 1211 nationally - a number worth ignoring, since it's statistical noise rather than a real trend. Source: USGS Open-File Report 2010-1119. Newport, OR sits at national rank 1121 for growth (1.16 ft/yr), one reference point among the 1211 scored segments, 2648 miles from here. 1.6 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.
