La Selva Beach, CA Coastal Erosion Rate
Shoreline change 1.3 miles northwest of La Selva Beach, CA
1.3 miles northwest of La Selva Beach, 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 "La Selva Beach" means on this page
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 La Selva Beach, CA. Centered near 36.94°N, 121.87°W. 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.
Where this fits nationally
This reading comes from 56 individual transects averaged together, 11% of which measured erosion rather than growth. USGS's confidence interval here is ±0.43 ft/yr. Taken at face value, this segment's raw 0.13 ft/yr reading would land it 878 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. Rank 1124 nationally for growth belongs to Santa Monica, CA, 275 miles from this stretch, measured at 1.21 ft/yr. 2.5 miles up the coast, Rio del Mar, CA shows the same lack of a significant trend.
