Waldport, OR Coastal Erosion Rate
Is the coast eroding 0.4 miles west of Waldport, OR?
The coast 0.4 miles west of Waldport, 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 this reading actually covers
Nothing here is parcel-level. USGS's raw transects run every few hundred feet along the shore; this page averages the ones nearest Waldport, OR into one ~3.5-mile reading rather than picking a single arbitrary line to represent the area. Centered near 44.42°N, 124.07°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.
How solid is this number
This reading comes from 2 individual transects averaged together, 100% of which measured erosion rather than growth. USGS's confidence interval here is ±1.57 ft/yr. Taken at face value, this segment's raw -0.45 ft/yr reading would land it 323 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 1035 nationally for growth belongs to Port St. Joe, FL, 2329 miles from this stretch, measured at 0.56 ft/yr. Waldport, OR, 1.4 miles off, is the adjacent measured stretch, itself no significant trend.
Not this whole stretch, just Waldport itself: the Coastal Change Hazards Portal is USGS's own live version of this data.
