Pacific City, OR Coastal Erosion Rate
Is the coast eroding 3.1 miles north of Pacific City, OR?
3.1 miles north of Pacific 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 Pacific City, OR. Centered near 45.25°N, 123.96°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.
Where this fits nationally
94 transects feed this segment's number; 91% of them individually measured retreat. The published margin on this reading runs ±1.52 ft/yr. Taken at face value, this segment's raw -0.4 ft/yr reading would land it 351 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: Margate City, NJ, 2521 miles away, ranks 1076 of 1211 nationally for growth, 0.8 ft/yr. 3.6 miles up the coast, Beaver, OR shows the same lack of a significant trend.
