Inverness, CA Coastal Erosion Rate
Shoreline change 9.1 miles southwest of Inverness, CA
The coast 9.1 miles southwest 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.
The grain of this number
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 38.01°N, 123.00°W. USGS's California assessment last surveyed this stretch through 1852-2016, computing the rate with its LRR method. Other US regions were surveyed in different years, sometimes decades apart, so this page states its own rather than implying one national vintage.
What backs this reading up
101 transects feed this segment's number; 100% of them individually measured retreat. Uncertainty on this specific number: 0.47 ft/yr either side. Taken at face value, this segment's raw -0.27 ft/yr reading would land it 428 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. Rank 1184 nationally for growth belongs to Quinby, VA, 2557 miles from this stretch, measured at 3.29 ft/yr. 1.5 miles away, Inverness, CA is the nearest other measured stretch: also no significant trend.
