York Harbor, ME Coastal Erosion Rate
Is the coast eroding 1.2 miles northeast of York Harbor, ME?
The coast 1.2 miles northeast of York Harbor, ME 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 this reading actually covers
Nothing here is parcel-level. USGS's raw transects run every few hundred feet along the shore; this page averages the ones nearest York Harbor, ME into one ~3.5-mile reading rather than picking a single arbitrary line to represent the area. Centered near 43.15°N, 70.63°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 39 individual transects averaged together, 28% of which measured erosion rather than growth. The published margin on this reading runs ±0.11 ft/yr. Taken at face value, this segment's raw 0.03 ft/yr reading would land it 798 of 1211 nationally - a number worth ignoring, since it's statistical noise rather than a real trend. Source: USGS Open-File Report 2010-1119. Rank 1043 nationally for growth belongs to Inwood, NY, 243 miles from this stretch, measured at 0.59 ft/yr. 1.2 miles up the coast, Cape Neddick, ME shows the same lack of a significant trend.
