San Buenaventura (Ventura), CA Coastal Erosion Rate
Shoreline change 2.1 miles west of San Buenaventura (Ventura), CA
Good news, and an honest one: USGS's data can't distinguish this stretch, 2.1 miles west of San Buenaventura (Ventura), CA, from a flat trend. Whatever small movement it measured here is statistical noise, not a reliable direction, so none is claimed.
What "San Buenaventura (Ventura)" 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 San Buenaventura (Ventura), CA, rather than showing one arbitrary line. Segment center: 34.27, -119.29. 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.
How solid is this number
55 transects feed this segment's number; 38% of them individually measured retreat. Uncertainty on this specific number: 0.67 ft/yr either side. The unadjusted figure here, 0.35 ft/yr, would place it 985 of 1211 if ranked directly - but an unreliable rank isn't a useful one, which is exactly why "no significant trend" is the headline instead. Source: USGS National Shoreline Change data release (ScienceBase, DOI 10.5066/P94J0K7Z), Kratzmann 2024 / Data Report 1187. Long Beach, CA sits at national rank 1135 for growth (1.31 ft/yr), one reference point among the 1211 scored segments, 73 miles from here. San Buenaventura (Ventura), CA, 1.2 miles off, is the adjacent measured stretch, reading slight erosion at 0.25 ft/yr.
