Kennebunkport, ME Coastal Erosion Rate
Shoreline change 2.1 miles southwest of Kennebunkport, ME
2.1 miles southwest of Kennebunkport, 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 "Kennebunkport" means on this page
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 Kennebunkport, ME. Centered near 43.35°N, 70.50°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 46 individual transects averaged together, 39% of which measured erosion rather than growth. USGS's confidence interval here is ±0.22 ft/yr. Taken at face value, this segment's raw 0.04 ft/yr reading would land it 811 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: Port St. Joe, FL, 1245 miles away, ranks 1067 of 1211 nationally for growth, 0.73 ft/yr. Kennebunkport, ME, 1.3 miles off, is the adjacent measured stretch, reading slight accretion (beach growing) at 0.22 ft/yr.
Not this whole stretch, just Kennebunkport itself: the Coastal Change Hazards Portal is USGS's own live version of this data.
