Camp Pendleton South, CA Coastal Erosion Rate
What USGS measures 2 miles south of Camp Pendleton South, CA
2 miles south of Camp Pendleton South, CA: USGS's transects didn't pick up a trend here that beats the survey's own uncertainty. That's the majority case nationally, and for this stretch specifically it means the coast is holding, not that the data failed to find anything.
What this reading actually covers
This is a roughly 3.5-mile stretch of coast, not one address or parcel - USGS's own transects run every few hundred feet, but that's finer than any one property needs, so this page reports the stretch nearest Camp Pendleton South, CA. Centered near 33.20°N, 117.39°W. 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.
Where this fits nationally
Averaging 90 separate transects produced this segment's rate, with 26% individually reading as erosion, rather than relying on any single survey line. The published margin on this reading runs ±0.35 ft/yr. Taken at face value, this segment's raw 0.17 ft/yr reading would land it 907 of 1211 nationally - a number worth ignoring, since it's statistical noise rather than a real trend. Source: USGS National Shoreline Change data release (ScienceBase, DOI 10.5066/P94J0K7Z), Kratzmann 2024 / Data Report 1187. For scale: Warrenton, OR, 962 miles away, ranks 1196 of 1211 nationally for growth, 4.64 ft/yr. 1.9 miles up the coast, Camp Pendleton South, CA shows the same lack of a significant trend.
