Inverness, CA Coastal Erosion Rate
What USGS measures 7.6 miles southwest of Inverness, CA
Nothing alarming measured 7.6 miles southwest of Inverness, 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
Inverness, CA is the nearest named place, 7.6 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: 38.02, -122.97. 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
This reading comes from 23 individual transects averaged together, 83% of which measured erosion rather than growth. USGS's confidence interval here is ±0.29 ft/yr. The unadjusted figure here, -0.11 ft/yr, would place it 639 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. Rank 1153 nationally for growth belongs to Orick, CA, 241 miles from this stretch, measured at 1.86 ft/yr. Inverness, CA, 1.3 miles off, is the adjacent measured stretch, itself no significant trend.
Not this whole stretch, just Inverness itself: the Coastal Change Hazards Portal is USGS's own live version of this data.
