Chincoteague, VA Coastal Erosion Rate
Shoreline change 2.1 miles east of Chincoteague, VA
The coast 2.1 miles east of Chincoteague, VA is actually gaining ground, not losing it: USGS's transects measure 1.09 feet of accretion a year here, sediment building up rather than washing away. At that rate, the shoreline has gained roughly 10.9 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 Chincoteague, VA. Centered near 37.96°N, 75.32°W. USGS's New England / Mid-Atlantic assessment last surveyed this stretch through 2007-2009, computing the rate with its LRR method. Other US regions were surveyed in different years, sometimes decades apart, so this page states its own rather than implying one national vintage.
25 years at this rate
Holding the 1.09 ft/yr accretion rate 2.1 miles east of Chincoteague, VA for 25 years would add roughly 27 feet of shoreline, again assuming nothing about the local sediment supply changes.
Where this fits nationally
This reading comes from 78 individual transects averaged together, 0% of which measured erosion rather than growth. USGS's confidence interval here is ±0.43 ft/yr. Sorted from fastest erosion to fastest growth across all 1211 measured segments nationally, this one lands at 1119. Source: USGS Open-File Report 2010-1119. Rank 1040 nationally for growth belongs to Manhattan Beach, CA, 2406 miles from this stretch, measured at 0.58 ft/yr, 0.5x this stretch's rate. Chincoteague, VA, 1.9 miles off, is the adjacent measured stretch, itself no significant trend.
