Fort Dick, CA Coastal Erosion Rate
Is the coast eroding 4.2 miles southwest of Fort Dick, CA?
Nothing alarming measured 4.2 miles southwest of Fort Dick, CA: whatever shift USGS's transects picked up here is too small to call reliably one way or the other, which this site reports as "no significant trend" rather than forcing a direction.
What this reading actually covers
Fort Dick, CA is the nearest named place, 4.2 miles away, to a ~3.5-mile stretch of coast USGS has surveyed - the reading below covers that whole stretch, not a single property in it. Segment center: 41.83, -124.23. Survey years: 1852-2016, method LRR, from USGS's California 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.
How solid is this number
13 transects feed this segment's number; 100% of them individually measured retreat. Uncertainty on this specific number: 0.17 ft/yr either side. The unadjusted figure here, -0.06 ft/yr, would place it 702 of 1211 if ranked directly - but an unreliable rank isn't a useful one, which is exactly why "no significant trend" is the headline instead. Source: USGS National Shoreline Change data release (ScienceBase, DOI 10.5066/P94J0K7Z), Kratzmann 2024 / Data Report 1187. For scale: North Wildwood, NJ, 2571 miles away, ranks 1193 of 1211 nationally for growth, 4.21 ft/yr. Crescent City, CA, 1.7 miles off, is the adjacent measured stretch, itself no significant trend.
Not this whole stretch, just Fort Dick itself: the Coastal Change Hazards Portal is USGS's own live version of this data.
