Carpinteria, CA Coastal Erosion Rate
Shoreline change 1.5 miles southeast of Carpinteria, CA
Nothing alarming measured 1.5 miles southeast of Carpinteria, 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 this reading actually covers
Carpinteria, CA is the nearest named place, 1.5 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: 34.37, -119.48. 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
10 transects feed this segment's number; 80% of them individually measured retreat. The published margin on this reading runs ±0.08 ft/yr. The unadjusted figure here, -0.04 ft/yr, would place it 739 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: Gardiner, OR, 696 miles away, ranks 1082 of 1211 nationally for growth, 0.82 ft/yr. 0.5 miles up the coast, Carpinteria, CA shows the same lack of a significant trend.
