Albion, CA Coastal Erosion Rate

Is the coast eroding 2.1 miles south of Albion, CA?

Slight accretion (beach growing)

The coast 2.1 miles south of Albion, CA is actually gaining ground, not losing it: USGS's transects measure 0.3 feet of accretion a year here, sediment building up rather than washing away. At that rate, the shoreline has gained roughly 3 feet over the last decade.

What "Albion" means on this page

USGS surveys the coast in transects spaced a few hundred feet apart; this page groups the nearest ones into a single ~3.5-mile reading for the stretch closest to Albion, CA, rather than showing one arbitrary line. Segment center: 39.19, -123.76. 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 0.3 ft/yr means over time

Holding the 0.3 ft/yr accretion rate 2.1 miles south of Albion, CA for 25 years would add roughly 8 feet of shoreline, again assuming nothing about the local sediment supply changes.

Where this fits nationally

Averaging 17 separate transects produced this segment's rate, with 14% individually reading as erosion, rather than relying on any single survey line. USGS's confidence interval here is ±0.18 ft/yr. Among the 1211 US coastal segments with a measurable trend, this one ranks 963 for erosion, 1 being the fastest-retreating coast in the dataset. Source: USGS National Shoreline Change data release (ScienceBase, DOI 10.5066/P94J0K7Z), Kratzmann 2024 / Data Report 1187. For scale: Ocean City, NJ, 2598 miles away, ranks 1162 of 1211 nationally for growth, 2.2 ft/yr, 7.3x this stretch's rate. 5.6 miles away, Little River, CA is the nearest other measured stretch: slight erosion at 0.17 ft/yr.

Not this whole stretch, just Albion itself: the Coastal Change Hazards Portal is USGS's own live version of this data.
