El Segundo, CA Coastal Erosion Rate
Shoreline change 0.5 miles northwest of El Segundo, CA
Unusual good news for this stretch: the shoreline 0.5 miles northwest of El Segundo, CA has grown by a measured 1.04 feet a year on average, per USGS's long-term transect data for this section. At that rate, the shoreline has gained roughly 10.4 feet over the last decade.
The grain of this number
El Segundo, CA is the nearest named place, 0.5 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: 33.92, -118.43. USGS's California assessment last surveyed this stretch through 1852-2016, computing the rate with its LRR method. Other US regions were surveyed in different years, sometimes decades apart, so this page states its own rather than implying one national vintage.
What 1.04 ft/yr means over time
Holding the 1.04 ft/yr accretion rate 0.5 miles northwest of El Segundo, CA for 25 years would add roughly 26 feet of shoreline, again assuming nothing about the local sediment supply changes.
Where this fits nationally
Averaging 37 separate transects produced this segment's rate, with 0% individually reading as erosion, rather than relying on any single survey line. Uncertainty on this specific number: 0.41 ft/yr either side. This segment ranks 1114 of 1211 measured US coastal segments, ordered from fastest erosion to fastest growth. Source: USGS National Shoreline Change data release (ScienceBase, DOI 10.5066/P94J0K7Z), Kratzmann 2024 / Data Report 1187. For scale: Camp Pendleton South, CA, 71 miles away, ranks 1024 of 1211 nationally for growth, 0.49 ft/yr, 0.5x this stretch's rate. Manhattan Beach, CA, 1.9 miles off, is the adjacent measured stretch, reading slight accretion (beach growing) at 0.58 ft/yr.
