Heceta Beach, OR Coastal Erosion Rate
What USGS measures 4.5 miles north of Heceta Beach, OR
Nothing alarming measured 4.5 miles north of Heceta Beach, OR: whatever shift USGS's transects picked up here is too small to call reliably one way or the other, which this site reports as "no significant trend" rather than forcing a direction.
What this reading actually covers
Heceta Beach, OR is the nearest named place, 4.5 miles away, to a ~3.5-mile stretch of coast USGS has surveyed - the reading below covers that whole stretch, not a single property in it. Segment center: 44.09, -124.12. 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.
What backs this reading up
63 transects feed this segment's number; 8% of them individually measured retreat. The published margin on this reading runs ±2.63 ft/yr. The unadjusted figure here, 0.73 ft/yr, would place it 1071 of 1211 if ranked directly - but an unreliable rank isn't a useful one, which is exactly why "no significant trend" is the headline instead. Source: USGS Open-File Report 2012-1008. Rank 1045 nationally for growth belongs to Gardiner, OR, 24 miles from this stretch, measured at 0.59 ft/yr. 1.7 miles up the coast, Heceta Beach, OR shows the same lack of a significant trend.
