Lompoc, CA Coastal Erosion Rate
What USGS measures 11.2 miles south of Lompoc, CA
Nothing alarming measured 11.2 miles south of Lompoc, 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 "Lompoc" means on this page
Lompoc, CA is the nearest named place, 11.2 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: 34.50, -120.50. 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
46 transects feed this segment's number; 100% of them individually measured retreat. The published margin on this reading runs ±0.35 ft/yr. The unadjusted figure here, -0.2 ft/yr, would place it 507 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. Dover Beaches South, NJ sits at national rank 994 for growth (0.4 ft/yr), one reference point among the 1211 scored segments, 2552 miles from here. 2.2 miles away, Lompoc, CA is the nearest other measured stretch: also no significant trend.
