Cape Neddick, ME Coastal Erosion Rate

Is the coast eroding 0.3 miles southeast of Cape Neddick, ME?

No significant trend

0.3 miles southeast of Cape Neddick, ME: 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 Cape Neddick, ME. Centered near 43.17°N, 70.62°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.

Where this fits nationally

This reading comes from 25 individual transects averaged together, 28% of which measured erosion rather than growth. USGS's confidence interval here is ±0.13 ft/yr. Taken at face value, this segment's raw 0.13 ft/yr reading would land it 875 of 1211 nationally - a number worth ignoring, since it's statistical noise rather than a real trend. Source: USGS Open-File Report 2010-1119. Point Lookout, NY sits at national rank 1194 for growth (4.23 ft/yr), one reference point among the 1211 scored segments, 233 miles from here. York Harbor, ME, 1.2 miles off, is the adjacent measured stretch, itself no significant trend.
