Fields Landing, CA Coastal Erosion Rate
Shoreline change 2.5 miles west of Fields Landing, CA
2.5 miles west of Fields Landing, CA, the coast is advancing, not retreating, at a measured 0.85 feet a year, sediment accumulating faster than any erosion USGS recorded here. At that rate, the shoreline has gained roughly 8.5 feet over the last decade.
What "Fields Landing" 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 Fields Landing, CA, rather than showing one arbitrary line. Segment center: 40.71, -124.26. 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 0.85 ft/yr means over time
Holding the 0.85 ft/yr accretion rate 2.5 miles west of Fields Landing, CA for 25 years would add roughly 21 feet of shoreline, again assuming nothing about the local sediment supply changes.
Where this fits nationally
This reading comes from 68 individual transects averaged together, 0% of which measured erosion rather than growth. USGS's confidence interval here is ±0.63 ft/yr. Among the 1211 US coastal segments with a measurable trend, this one ranks 1085 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. Mexico Beach, FL sits at national rank 1046 for growth (0.6 ft/yr), one reference point among the 1211 scored segments, 2296 miles from here. 2 miles away, Fields Landing, CA is the nearest other measured stretch: also no significant trend.
