Bertsch-Oceanview, CA Coastal Erosion Rate
What USGS measures 3.4 miles southeast of Bertsch-Oceanview, CA
Nothing alarming measured 3.4 miles southeast of Bertsch-Oceanview, 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 "Bertsch-Oceanview" means on this page
Bertsch-Oceanview, CA is the nearest named place, 3.4 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: 41.71, -124.14. 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
Averaging 73 separate transects produced this segment's rate, with 48% individually reading as erosion, rather than relying on any single survey line. Uncertainty on this specific number: 0.21 ft/yr either side. The unadjusted figure here, 0.02 ft/yr, would place it 794 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. For scale: Seal Beach, CA, 643 miles away, ranks 1053 of 1211 nationally for growth, 0.63 ft/yr. 2.3 miles up the coast, Bertsch-Oceanview, CA shows 0.41 ft/yr of accreting.
