What "Fort Dick" means on this page
USGS surveys the coast in transects spaced a few hundred feet apart; this page groups the nearest ones into a single ~3.5-mile reading for the stretch closest to Fort Dick, CA, rather than showing one arbitrary line. Segment center: 41.90, -124.21. USGS's California assessment last surveyed this stretch through 1852-2016, 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.
What 0.32 ft/yr means over time
Holding the 0.32 ft/yr accretion rate 2.9 miles northwest of Fort Dick, CA for 25 years would add roughly 8 feet of shoreline, again assuming nothing about the local sediment supply changes.
Where this fits nationally
Averaging 111 separate transects produced this segment's rate, with 0% individually reading as erosion, rather than relying on any single survey line.
