Is the coast eroding 7.3 miles southeast of Quinby, VA?
The coast 7.3 miles southeast of Quinby, VA is actually gaining ground, not losing it: USGS's transects measure 3.21 feet of accretion a year here, sediment building up rather than washing away. At that rate, the shoreline has gained roughly 32.1 feet over the last decade.
What "Quinby" means on this page
Nothing here is parcel-level. USGS's raw transects run every few hundred feet along the shore; this page averages the ones nearest Quinby, VA into one ~3.5-mile reading rather than picking a single arbitrary line to represent the area. Centered near 37.46°N, 75.67°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
Holding the 3.21 ft/yr accretion rate 7.3 miles southeast of Quinby, VA for 25 years would add roughly 80 feet of shoreline, again assuming nothing about the local sediment supply changes.
