Yachats, OR Coastal Erosion Rate
What USGS measures 8 miles south of Yachats, OR
Nothing alarming measured 8 miles south of Yachats, OR: whatever shift USGS's transects picked up here is too small to call reliably one way or the other, which this site reports as "no significant trend" rather than forcing a direction.
What this reading actually covers
Yachats, OR is the nearest named place, 8 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: 44.20, -124.11. USGS's Pacific Northwest assessment last surveyed this stretch through 2002-2011, 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.
How solid is this number
This reading comes from 56 individual transects averaged together, 95% of which measured erosion rather than growth. Uncertainty on this specific number: 1.08 ft/yr either side. The unadjusted figure here, -0.43 ft/yr, would place it 336 of 1211 if ranked directly - but an unreliable rank isn't a useful one, which is exactly why "no significant trend" is the headline instead. Source: USGS Open-File Report 2012-1008. Rank 1159 nationally for growth belongs to Atlantic City, NJ, 2542 miles from this stretch, measured at 2.07 ft/yr. 2.4 miles away, Yachats, OR is the nearest other measured stretch: also no significant trend.
