Davenport, CA Coastal Erosion Rate
What USGS measures 2.1 miles west of Davenport, CA
Nothing alarming measured 2.1 miles west of Davenport, 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.
What "Davenport" means on this page
Davenport, CA is the nearest named place, 2.1 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: 37.03, -122.22. 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.
Where this fits nationally
This reading comes from 2 individual transects averaged together, 100% of which measured erosion rather than growth. USGS's confidence interval here is ±0.42 ft/yr. The unadjusted figure here, -0.34 ft/yr, would place it 386 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. Warrenton, OR sits at national rank 1195 for growth (4.41 ft/yr), one reference point among the 1211 scored segments, 637 miles from here. Davenport, CA, 1.5 miles off, is the adjacent measured stretch, reading slight erosion at 0.26 ft/yr.
