Lincoln Beach, OR Coastal Erosion Rate

What USGS measures 1.3 miles north of Lincoln Beach, OR

No significant trend

Nothing alarming measured 1.3 miles north of Lincoln Beach, 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 "Lincoln Beach" means on this page

Lincoln Beach, OR is the nearest named place, 1.3 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: 44.89, -124.03. 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.

What backs this reading up

Averaging 74 separate transects produced this segment's rate, with 4% individually reading as erosion, rather than relying on any single survey line. USGS's confidence interval here is ±0.95 ft/yr. The unadjusted figure here, 0.54 ft/yr, would place it 1031 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 1011 nationally for growth belongs to Pajaro Dunes, CA, 566 miles from this stretch, measured at 0.45 ft/yr. 1.8 miles away, Lincoln Beach, OR is the nearest other measured stretch: also no significant trend.

Not this whole stretch, just Lincoln Beach itself: the Coastal Change Hazards Portal is USGS's own live version of this data.
