Inverness, CA Coastal Erosion Rate
What USGS measures 7.6 miles west of Inverness, CA
The coast 7.6 miles west of Inverness, CA shows no statistically significant trend either way. USGS's transects measured a rate here, but it's smaller than the survey's own margin of error for this stretch, so calling it "eroding" or "growing" would overstate what the data actually shows.
What "Inverness" means on this page
Nothing here is parcel-level. USGS's raw transects run every few hundred feet along the shore; this page averages the ones nearest Inverness, CA into one ~3.5-mile reading rather than picking a single arbitrary line to represent the area. Centered near 38.05°N, 122.99°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.
How solid is this number
118 transects feed this segment's number; 31% of them individually measured retreat. Uncertainty on this specific number: 0.37 ft/yr either side. Taken at face value, this segment's raw 0.11 ft/yr reading would land it 865 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. Mexico Beach, FL sits at national rank 1015 for growth (0.47 ft/yr), one reference point among the 1211 scored segments, 2211 miles from here. 1.9 miles away, Inverness, CA is the nearest other measured stretch: also no significant trend.
