Del Mar, CA Coastal Erosion Rate
Shoreline change 4.4 miles south of Del Mar, CA
Nothing alarming measured 4.4 miles south of Del Mar, 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 "Del Mar" means on this page
Del Mar, CA is the nearest named place, 4.4 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: 32.90, -117.25. 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.
What backs this reading up
107 transects feed this segment's number; 30% of them individually measured retreat. Uncertainty on this specific number: 0.48 ft/yr either side. The unadjusted figure here, 0.17 ft/yr, would place it 906 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. Rank 1172 nationally for growth belongs to East Atlantic Beach, NY, 2444 miles from this stretch, measured at 2.39 ft/yr. 2.7 miles up the coast, Del Mar, CA shows the same lack of a significant trend.
