Lincoln City, OR Coastal Erosion Rate
What USGS measures 1.4 miles north of Lincoln City, OR
1.4 miles north of Lincoln City, 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 this reading actually covers
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 Lincoln City, OR. Centered near 45.00°N, 124.01°W. USGS's Pacific Northwest assessment last surveyed this stretch through 2002-2011, computing the rate with its LRR method. Other US regions were surveyed in different years, sometimes decades apart, so this page states its own rather than implying one national vintage.
How solid is this number
This reading comes from 100 individual transects averaged together, 75% of which measured erosion rather than growth. The published margin on this reading runs ±0.74 ft/yr. Taken at face value, this segment's raw -0.13 ft/yr reading would land it 598 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: Chincoteague, VA, 2528 miles away, ranks 1119 of 1211 nationally for growth, 1.09 ft/yr. 2.7 miles away, Neotsu, OR is the nearest other measured stretch: also no significant trend.
Not this whole stretch, just Lincoln City itself: the Coastal Change Hazards Portal is USGS's own live version of this data.
