Newport East, RI Coastal Erosion Rate
Is the coast eroding 9.6 miles east of Newport East, RI?
The coast 9.6 miles east of Newport East, RI has been retreating at a measured 0.21 feet a year, USGS's own long-term rate for this stretch, built from historical shoreline positions rather than a single survey. At that rate, the shoreline has lost roughly 2.1 feet over the last decade.
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 Newport East, RI. Centered near 41.51°N, 71.10°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.
25 years at this rate
If 0.21 ft/yr holds for the next 25 years, the coast 9.6 miles east of Newport East, RI would retreat roughly 5 more feet, a projection, not a certainty: erosion rates shift with storms, sediment supply and any armoring built in the meantime.
What backs this reading up
67 transects feed this segment's number; 100% of them individually measured retreat. The published margin on this reading runs ±0.15 ft/yr. Sorted from fastest erosion to fastest growth across all 1211 measured segments nationally, this one lands at 492. Source: USGS Open-File Report 2010-1119. Ipswich, MA sits at national rank 432 for erosion (0.26 ft/yr), one reference point among the 1211 scored segments, 85 miles from here. 2.7 miles away, Bliss Corner, MA is the nearest other measured stretch: also no significant trend.
Not this whole stretch, just Newport East itself: the Coastal Change Hazards Portal is USGS's own live version of this data.
