Forks, WA Coastal Erosion Rate

Shoreline change 10.1 miles southwest of Forks, WA

No significant trend

Nothing alarming measured 10.1 miles southwest of Forks, WA: 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

Forks, WA is the nearest named place, 10.1 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: 47.88, -124.58. 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

This reading comes from 18 individual transects averaged together, 17% of which measured erosion rather than growth. The published margin on this reading runs ±0.43 ft/yr. The unadjusted figure here, 0.15 ft/yr, would place it 893 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 1028 nationally for growth belongs to Port Orford, OR, 350 miles from this stretch, measured at 0.53 ft/yr. Taholah, WA, 39.9 miles off, is the adjacent measured stretch, reading slight erosion at 0.61 ft/yr.
