Neahkahnie, OR Coastal Erosion Rate
What USGS measures 0.8 miles northwest of Neahkahnie, OR
0.8 miles northwest of Neahkahnie, 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 "Neahkahnie" 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 Neahkahnie, OR. Centered near 45.74°N, 123.95°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.
What backs this reading up
32 transects feed this segment's number; 31% of them individually measured retreat. The published margin on this reading runs ±0.81 ft/yr. Taken at face value, this segment's raw 0.42 ft/yr reading would land it 1003 of 1211 nationally - a number worth ignoring, since it's statistical noise rather than a real trend. Source: USGS Open-File Report 2012-1008. Newport, OR sits at national rank 1121 for growth (1.16 ft/yr), one reference point among the 1211 scored segments, 76 miles from here. 3 miles up the coast, Manzanita, OR shows 1.28 ft/yr of accreting.
