Barview, OR Coastal Erosion Rate
Is the coast eroding 6.4 miles southwest of Barview, OR?
6.4 miles southwest of Barview, OR: 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 "Barview" 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 Barview, OR. Centered near 43.27°N, 124.37°W. 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.
How solid is this number
Averaging 2 separate transects produced this segment's rate, with 0% individually reading as erosion, rather than relying on any single survey line. Uncertainty on this specific number: 2.17 ft/yr either side. Taken at face value, this segment's raw 1.24 ft/yr reading would land it 1127 of 1211 nationally - a number worth ignoring, since it's statistical noise rather than a real trend. Source: USGS Open-File Report 2012-1008. For scale: Sarita, TX, 1871 miles away, ranks 1087 of 1211 nationally for growth, 0.88 ft/yr. 1.7 miles away, Barview, OR is the nearest other measured stretch: also no significant trend.
Not this whole stretch, just Barview itself: the Coastal Change Hazards Portal is USGS's own live version of this data.
