Port Orford, OR Coastal Erosion Rate
What USGS measures 8.3 miles southeast of Port Orford, OR
Nothing alarming measured 8.3 miles southeast of Port Orford, 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.
The grain of this number
Port Orford, OR is the nearest named place, 8.3 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: 42.65, -124.40. 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.
What backs this reading up
32 transects feed this segment's number; 94% of them individually measured retreat. USGS's confidence interval here is ±1.38 ft/yr. The unadjusted figure here, -0.34 ft/yr, would place it 381 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 1113 nationally for growth belongs to Ocean Park, WA, 270 miles from this stretch, measured at 1.04 ft/yr. 3.2 miles up the coast, Nesika Beach, OR shows the same lack of a significant trend.
