Brookings, OR Coastal Erosion Rate
Shoreline change 0.9 miles northwest of Brookings, OR
Good news, and an honest one: USGS's data can't distinguish this stretch, 0.9 miles northwest of Brookings, OR, from a flat trend. Whatever small movement it measured here is statistical noise, not a reliable direction, so none is claimed.
The grain of this number
USGS surveys the coast in transects spaced a few hundred feet apart; this page groups the nearest ones into a single ~3.5-mile reading for the stretch closest to Brookings, OR, rather than showing one arbitrary line. Segment center: 42.08, -124.32. The survey behind it runs to 2002-2011, in USGS's Pacific Northwest 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 17 separate transects produced this segment's rate, with 18% individually reading as erosion, rather than relying on any single survey line. USGS's confidence interval here is ±1.18 ft/yr. The unadjusted figure here, 0.45 ft/yr, would place it 1009 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. Copalis Beach, WA sits at national rank 1105 for growth (0.99 ft/yr), one reference point among the 1211 scored segments, 350 miles from here. Brookings, OR, 1.2 miles off, is the adjacent measured stretch, itself no significant trend.
