What USGS measures 3 miles southeast of Port Hueneme, CA
Averaged across every transect USGS ran 3 miles southeast of Port Hueneme, CA, the shoreline has been moving inland at 0.44 feet a year, a real measured rate, not a regional estimate applied to this stretch. At that rate, the shoreline has lost roughly 4.4 feet over the last decade.
What "Port Hueneme" means on this page
Port Hueneme, CA is the nearest named place, 3 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: 34.13, -119.17. 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 0.44 ft/yr means over time
Run 3 miles southeast of Port Hueneme, CA's 0.44 ft/yr rate forward 25 years and it implies about 11 feet of further retreat, assuming nothing changes, which is exactly the assumption a seawall or nourishment project exists to break.
How solid is this number
Averaging 18 separate transects produced this segment's rate, with 100% individually reading as erosion, rather than relying on any single survey line. The published margin on this reading runs ±0.41 ft/yr. Among the 1211 US coastal segments with a measurable trend, this one ranks 332 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. Pleasure Point, CA sits at national rank 371 for erosion (0.36 ft/yr), one reference point among the 1211 scored segments, 251 miles from here. 1.8 miles away, Port Hueneme, CA is the nearest other measured stretch: slight erosion at 0.57 ft/yr.
