North Bend, OR Coastal Erosion Rate
Is the coast eroding 3.1 miles northwest of North Bend, OR?
3.1 miles northwest of North Bend, 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 "North Bend" 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 North Bend, OR. Centered near 43.44°N, 124.28°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.
Where this fits nationally
This reading comes from 55 individual transects averaged together, 73% of which measured erosion rather than growth. Uncertainty on this specific number: 0.55 ft/yr either side. Taken at face value, this segment's raw -0.04 ft/yr reading would land it 728 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: Panacea, FL, 2373 miles away, ranks 1107 of 1211 nationally for growth, 1 ft/yr. 1.9 miles away, Glasgow, OR is the nearest other measured stretch: also no significant trend.
