Gold Beach, OR Coastal Erosion Rate
Is the coast eroding 3.1 miles south of Gold Beach, OR?
3.1 miles south of Gold Beach, 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 Gold Beach, OR. Centered near 42.36°N, 124.42°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
80 transects feed this segment's number; 70% of them individually measured retreat. The published margin on this reading runs ±1.23 ft/yr. Taken at face value, this segment's raw -0.12 ft/yr reading would land it 615 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: Huntington Beach, CA, 691 miles away, ranks 993 of 1211 nationally for growth, 0.39 ft/yr. 2.7 miles up the coast, Gold Beach, OR shows the same lack of a significant trend.
Not this whole stretch, just Gold Beach itself: the Coastal Change Hazards Portal is USGS's own live version of this data.
