Oceanside, OR Coastal Erosion Rate
Shoreline change 0.5 miles south of Oceanside, OR
The coast 0.5 miles south of Oceanside, OR shows no statistically significant trend either way. USGS's transects measured a rate here, but it's smaller than the survey's own margin of error for this stretch, so calling it "eroding" or "growing" would overstate what the data actually shows.
The grain of this number
Nothing here is parcel-level. USGS's raw transects run every few hundred feet along the shore; this page averages the ones nearest Oceanside, OR into one ~3.5-mile reading rather than picking a single arbitrary line to represent the area. Centered near 45.45°N, 123.96°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
Averaging 68 separate transects produced this segment's rate, with 35% individually reading as erosion, rather than relying on any single survey line. Uncertainty on this specific number: 1.06 ft/yr either side. Taken at face value, this segment's raw 0.23 ft/yr reading would land it 939 of 1211 nationally - a number worth ignoring, since it's statistical noise rather than a real trend. Source: USGS Open-File Report 2012-1008. Rank 1206 nationally for growth belongs to Tiki Island, TX, 1934 miles from this stretch, measured at 6.14 ft/yr. 3.3 miles up the coast, Netarts, OR shows the same lack of a significant trend.
