Oxnard, CA Coastal Erosion Rate
What USGS measures 2.4 miles west of Oxnard, CA
Unusual good news for this stretch: the shoreline 2.4 miles west of Oxnard, CA has grown by a measured 0.86 feet a year on average, per USGS's long-term transect data for this section. At that rate, the shoreline has gained roughly 8.6 feet over the last decade.
What this reading actually covers
Nothing here is parcel-level. USGS's raw transects run every few hundred feet along the shore; this page averages the ones nearest Oxnard, CA into one ~3.5-mile reading rather than picking a single arbitrary line to represent the area. Centered near 34.20°N, 119.25°W. 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.
25 years at this rate
Holding the 0.86 ft/yr accretion rate 2.4 miles west of Oxnard, CA for 25 years would add roughly 22 feet of shoreline, again assuming nothing about the local sediment supply changes.
Where this fits nationally
121 transects feed this segment's number; 0% of them individually measured retreat. USGS's confidence interval here is ±0.38 ft/yr.
