Dunes City, OR Coastal Erosion Rate
What USGS measures 2.8 miles west of Dunes City, OR
Unusual good news for this stretch: the shoreline 2.8 miles west of Dunes City, OR has grown by a measured 0.67 feet a year on average, per USGS's long-term transect data for this section. At that rate, the shoreline has gained roughly 6.7 feet over the last decade.
What "Dunes City" 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 Dunes City, OR. Centered near 43.90°N, 124.15°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.
25 years at this rate
Holding the 0.67 ft/yr accretion rate 2.8 miles west of Dunes City, OR for 25 years would add roughly 17 feet of shoreline, again assuming nothing about the local sediment supply changes.
Where this fits nationally
102 transects feed this segment's number; 5% of them individually measured retreat. The published margin on this reading runs ±0.49 ft/yr. This segment ranks 1058 of 1211 measured US coastal segments, ordered from fastest erosion to fastest growth. Source: USGS Open-File Report 2012-1008. Panacea, FL sits at national rank 1107 for growth (1 ft/yr), one reference point among the 1211 scored segments, 2372 miles from here. 3.3 miles away, Florence, OR is the nearest other measured stretch: slight accretion (beach growing) at 0.8 ft/yr.
Not this whole stretch, just Dunes City itself: the Coastal Change Hazards Portal is USGS's own live version of this data.
