Scotia, CA Coastal Erosion Rate
Is the coast eroding 18.1 miles southwest of Scotia, CA?
18.1 miles southwest of Scotia, 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 "Scotia" 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 Scotia, CA. Centered near 40.30°N, 124.35°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.
What backs this reading up
This reading comes from 115 individual transects averaged together, 6% of which measured erosion rather than growth. Uncertainty on this specific number: 0.26 ft/yr either side. Taken at face value, this segment's raw 0.21 ft/yr reading would land it 930 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. Marina del Rey, CA sits at national rank 1118 for growth (1.07 ft/yr), one reference point among the 1211 scored segments, 546 miles from here. Scotia, CA, 3.3 miles off, is the adjacent measured stretch, itself no significant trend.
