Shelter Cove, CA Coastal Erosion Rate
What USGS measures 14.6 miles northwest of Shelter Cove, CA
Nothing alarming measured 14.6 miles northwest of Shelter Cove, 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.
The grain of this number
Shelter Cove, CA is the nearest named place, 14.6 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: 40.19, -124.26. The survey behind it runs to 1852-2016, in USGS's California assessment, using the LRR method. Shoreline surveys aren't repeated every year, so this is the most recent long-term measurement USGS has published for this coast, not a live reading.
Where this fits nationally
Averaging 86 separate transects produced this segment's rate, with 33% individually reading as erosion, rather than relying on any single survey line. Uncertainty on this specific number: 0.62 ft/yr either side. The unadjusted figure here, 0.07 ft/yr, would place it 832 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: Kennebunkport, ME, 2732 miles away, ranks 933 of 1211 nationally for growth, 0.22 ft/yr. Shelter Cove, CA, 1.7 miles off, is the adjacent measured stretch, itself no significant trend.
