Cannon Beach, OR Coastal Erosion Rate
What USGS measures right at Cannon Beach, OR
The coast right at Cannon Beach, 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.
What "Cannon Beach" means on this page
Nothing here is parcel-level. USGS's raw transects run every few hundred feet along the shore; this page averages the ones nearest Cannon Beach, OR into one ~3.5-mile reading rather than picking a single arbitrary line to represent the area. Centered near 45.89°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
66 transects feed this segment's number; 14% of them individually measured retreat. USGS's confidence interval here is ±2.1 ft/yr. Taken at face value, this segment's raw 0.59 ft/yr reading would land it 1044 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, 2514 miles away, ranks 1076 of 1211 nationally for growth, 0.8 ft/yr. 2.7 miles away, Cannon Beach, OR is the nearest other measured stretch: also no significant trend.
