Shelter Cove, CA Coastal Erosion Rate
Shoreline change 19.2 miles northwest of Shelter Cove, CA
19.2 miles northwest of Shelter Cove, CA: USGS's transects didn't pick up a trend here that beats the survey's own uncertainty. That's the majority case nationally, and for this stretch specifically it means the coast is holding, not that the data failed to find anything.
What "Shelter Cove" means on this page
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 Shelter Cove, CA. Centered near 40.23°N, 124.32°W. 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
This reading comes from 22 individual transects averaged together, 100% of which measured erosion rather than growth. Uncertainty on this specific number: 0.48 ft/yr either side. Taken at face value, this segment's raw -0.21 ft/yr reading would land it 494 of 1211 nationally - a number worth ignoring, since it's statistical noise rather than a real trend. Source: USGS National Shoreline Change data release (ScienceBase, DOI 10.5066/P94J0K7Z), Kratzmann 2024 / Data Report 1187. For scale: Fields Landing, CA, 36 miles away, ranks 1157 of 1211 nationally for growth, 2.04 ft/yr. 1.8 miles away, Shelter Cove, CA is the nearest other measured stretch: also no significant trend.
