Barview, OR Coastal Erosion Rate
Is the coast eroding 8 miles southwest of Barview, OR?
The coast 8 miles southwest of Barview, OR shows no statistically significant trend either way. USGS's transects measured a rate here, but it's smaller than the survey's own margin of error for this stretch, so calling it "eroding" or "growing" would overstate what the data actually shows.
What this reading actually covers
Nothing here is parcel-level. USGS's raw transects run every few hundred feet along the shore; this page averages the ones nearest Barview, OR into one ~3.5-mile reading rather than picking a single arbitrary line to represent the area. Centered near 43.25°N, 124.38°W. Survey years: 2002-2011, method LRR, from USGS's Pacific Northwest shoreline-change assessment. That's how current the data is here, real, but not a live feed, since a shoreline survey is a major undertaking, not an annual check-in.
Where this fits nationally
83 transects feed this segment's number; 66% of them individually measured retreat. Uncertainty on this specific number: 0.82 ft/yr either side. Taken at face value, this segment's raw -0.24 ft/yr reading would land it 455 of 1211 nationally - a number worth ignoring, since it's statistical noise rather than a real trend. Source: USGS Open-File Report 2012-1008. Rank 1181 nationally for growth belongs to Mexico Beach, FL, 2317 miles from this stretch, measured at 2.91 ft/yr. 1.7 miles up the coast, Barview, OR shows the same lack of a significant trend.
Not this whole stretch, just Barview itself: the Coastal Change Hazards Portal is USGS's own live version of this data.
