Shoreline change 1.7 miles southwest of San Buenaventura (Ventura), CA
Unusual good news for this stretch: the shoreline 1.7 miles southwest of San Buenaventura (Ventura), CA has grown by a measured 1.19 feet a year on average, per USGS's long-term transect data for this section. At that rate, the shoreline has gained roughly 11.9 feet over the last decade.
What "San Buenaventura (Ventura)" means on this page
San Buenaventura (Ventura), CA is the nearest named place, 1.7 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: 34.25, -119.27. 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 1.19 ft/yr means over time
Holding the 1.19 ft/yr accretion rate 1.7 miles southwest of San Buenaventura (Ventura), CA for 25 years would add roughly 30 feet of shoreline, again assuming nothing about the local sediment supply changes.
Where this fits nationally
Averaging 86 separate transects produced this segment's rate, with 5% individually reading as erosion, rather than relying on any single survey line. USGS's confidence interval here is ±0.84 ft/yr. Among the 1211 US coastal segments with a measurable trend, this one ranks 1122 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. Rank 1093 nationally for growth belongs to Inwood, NY, 2505 miles from this stretch, measured at 0.91 ft/yr, 0.8x this stretch's rate. San Buenaventura (Ventura), CA, 2.3 miles off, is the adjacent measured stretch, itself no significant trend.
