Palos Verdes Estates, CA Coastal Erosion Rate
Shoreline change 2.1 miles northeast of Palos Verdes Estates, CA
2.1 miles northeast of Palos Verdes Estates, CA, the coast is advancing, not retreating, at a measured 0.17 feet a year, sediment accumulating faster than any erosion USGS recorded here. At that rate, the shoreline has gained roughly 1.7 feet over the last decade.
What "Palos Verdes Estates" means on this page
Palos Verdes Estates, 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: 33.80, -118.40. 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.
What 0.17 ft/yr means over time
Holding the 0.17 ft/yr accretion rate 2.1 miles northeast of Palos Verdes Estates, CA for 25 years would add roughly 4 feet of shoreline, again assuming nothing about the local sediment supply changes.
What backs this reading up
111 transects feed this segment's number; 28% of them individually measured retreat. USGS's confidence interval here is ±0.1 ft/yr. Sorted from fastest erosion to fastest growth across all 1211 measured segments nationally, this one lands at 909. Source: USGS National Shoreline Change data release (ScienceBase, DOI 10.5066/P94J0K7Z), Kratzmann 2024 / Data Report 1187. For scale: Surfside Beach, TX, 1400 miles away, ranks 1059 of 1211 nationally for growth, 0.69 ft/yr, 4.1x this stretch's rate. 2 miles away, Palos Verdes Estates, CA is the nearest other measured stretch: slight erosion at 0.16 ft/yr.
