Bliss Corner, MA Coastal Erosion Rate
What USGS measures 4.6 miles south of Bliss Corner, MA
The coast 4.6 miles south of Bliss Corner, MA shows no statistically significant trend either way. USGS's transects measured a rate here, but it's smaller than the survey's own margin of error for this stretch, so calling it "eroding" or "growing" would overstate what the data actually shows.
What "Bliss Corner" means on this page
Nothing here is parcel-level. USGS's raw transects run every few hundred feet along the shore; this page averages the ones nearest Bliss Corner, MA into one ~3.5-mile reading rather than picking a single arbitrary line to represent the area. Centered near 41.54°N, 70.94°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.
What backs this reading up
35 transects feed this segment's number; 83% of them individually measured retreat. Uncertainty on this specific number: 0.11 ft/yr either side. Taken at face value, this segment's raw -0.11 ft/yr reading would land it 634 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: Seaside, OR, 2613 miles away, ranks 1136 of 1211 nationally for growth, 1.36 ft/yr. 1.4 miles away, Bliss Corner, MA is the nearest other measured stretch: also no significant trend.
Not this whole stretch, just Bliss Corner itself: the Coastal Change Hazards Portal is USGS's own live version of this data.
