Bertsch-Oceanview, CA Coastal Erosion Rate
Shoreline change 1.2 miles southeast of Bertsch-Oceanview, CA
The coast 1.2 miles southeast of Bertsch-Oceanview, CA is actually gaining ground, not losing it: USGS's transects measure 0.41 feet of accretion a year here, sediment building up rather than washing away. At that rate, the shoreline has gained roughly 4.1 feet over the last decade.
The grain of this number
Bertsch-Oceanview, CA is the nearest named place, 1.2 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: 41.74, -124.16. 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 0.41 ft/yr means over time
Holding the 0.41 ft/yr accretion rate 1.2 miles southeast of Bertsch-Oceanview, CA for 25 years would add roughly 10 feet of shoreline, again assuming nothing about the local sediment supply changes.
Where this fits nationally
60 transects feed this segment's number; 0% of them individually measured retreat. USGS's confidence interval here is ±0.21 ft/yr. This segment ranks 1001 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: Santa Monica, CA, 613 miles away, ranks 932 of 1211 nationally for growth, 0.21 ft/yr, 0.5x this stretch's rate. 2.3 miles up the coast, Bertsch-Oceanview, CA shows the same lack of a significant trend.
