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 Gardiner, OR. Centered near 43.74°N, 124.18°W. USGS's Pacific Northwest assessment last surveyed this stretch through 2002-2011, 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 0.59 ft/yr accretion rate 3.7 miles west of Gardiner, OR for 25 years would add roughly 15 feet of shoreline, again assuming nothing about the local sediment supply changes.
