Leggett, CA Coastal Erosion Rate
What USGS measures 7.6 miles southwest of Leggett, CA
7.6 miles southwest of Leggett, 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.
The grain of this number
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 Leggett, CA. Centered near 39.80°N, 123.84°W. 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.
Where this fits nationally
This reading comes from 96 individual transects averaged together, 85% of which measured erosion rather than growth. The published margin on this reading runs ±0.69 ft/yr. Taken at face value, this segment's raw -0.16 ft/yr reading would land it 553 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: Sarita, TX, 1744 miles away, ranks 1038 of 1211 nationally for growth, 0.58 ft/yr. 2.8 miles up the coast, Leggett, CA shows the same lack of a significant trend.
