Sagamore, MA Coastal Erosion Rate
Shoreline change 0.7 miles southeast of Sagamore, MA
Nothing alarming measured 0.7 miles southeast of Sagamore, MA: whatever shift USGS's transects picked up here is too small to call reliably one way or the other, which this site reports as "no significant trend" rather than forcing a direction.
What this reading actually covers
Sagamore, MA is the nearest named place, 0.7 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: 41.78, -70.52. 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.
How solid is this number
25 transects feed this segment's number; 56% of them individually measured retreat. USGS's confidence interval here is ±0.46 ft/yr. The unadjusted figure here, -0.04 ft/yr, would place it 723 of 1211 if ranked directly - but an unreliable rank isn't a useful one, which is exactly why "no significant trend" is the headline instead. Source: USGS Open-File Report 2010-1119. Quinby, VA sits at national rank 1183 for growth (3.21 ft/yr), one reference point among the 1211 scored segments, 405 miles from here. 1.6 miles away, Sandwich, MA is the nearest other measured stretch: also no significant trend.
