Weekapaug, RI Coastal Erosion Rate
What USGS measures 0.8 miles southeast of Weekapaug, RI
The coast 0.8 miles southeast of Weekapaug, RI 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.
The grain of this number
Nothing here is parcel-level. USGS's raw transects run every few hundred feet along the shore; this page averages the ones nearest Weekapaug, RI into one ~3.5-mile reading rather than picking a single arbitrary line to represent the area. Centered near 41.33°N, 71.75°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 82 individual transects averaged together, 78% of which measured erosion rather than growth. The published margin on this reading runs ±0.15 ft/yr. Taken at face value, this segment's raw -0.13 ft/yr reading would land it 596 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 1015 nationally for growth belongs to Mexico Beach, FL, 1095 miles from this stretch, measured at 0.47 ft/yr. 2.3 miles up the coast, Weekapaug, RI shows 0.12 ft/yr of eroding.
Not this whole stretch, just Weekapaug itself: the Coastal Change Hazards Portal is USGS's own live version of this data.
