Bayshore, OR Coastal Erosion Rate

Is the coast eroding 2.8 miles north of Bayshore, OR?

No significant trend

Nothing alarming measured 2.8 miles north of Bayshore, 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 "Bayshore" means on this page

Bayshore, OR is the nearest named place, 2.8 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: 44.48, -124.08. 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.

How solid is this number

This reading comes from 6 individual transects averaged together, 0% of which measured erosion rather than growth. USGS's confidence interval here is ±1.69 ft/yr. The unadjusted figure here, 0.81 ft/yr, would place it 1080 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. For scale: Dover Beaches South, NJ, 2537 miles away, ranks 994 of 1211 nationally for growth, 0.4 ft/yr. Bayshore, OR, 2.3 miles off, is the adjacent measured stretch, reading accretion (beach growing) at 1.23 ft/yr.
