Qui-nai-elt Village, WA Coastal Erosion Rate
What USGS measures 1 miles west of Qui-nai-elt Village, WA
Unusual good news for this stretch: the shoreline 1 miles west of Qui-nai-elt Village, WA has grown by a measured 1.04 feet a year on average, per USGS's long-term transect data for this section. At that rate, the shoreline has gained roughly 10.4 feet over the last decade.
The grain of this number
USGS surveys the coast in transects spaced a few hundred feet apart; this page groups the nearest ones into a single ~3.5-mile reading for the stretch closest to Qui-nai-elt Village, WA, rather than showing one arbitrary line. Segment center: 47.25, -124.21. USGS's Pacific Northwest assessment last surveyed this stretch through 2002-2011, computing the rate with its LRR method. Other US regions were surveyed in different years, sometimes decades apart, so this page states its own rather than implying one national vintage.
What 1.04 ft/yr means over time
Holding the 1.04 ft/yr accretion rate 1 miles west of Qui-nai-elt Village, WA for 25 years would add roughly 26 feet of shoreline, again assuming nothing about the local sediment supply changes.
How solid is this number
90 transects feed this segment's number; 1% of them individually measured retreat. The published margin on this reading runs ±0.65 ft/yr. This segment ranks 1112 of 1211 measured US coastal segments, ordered from fastest erosion to fastest growth. Source: USGS Open-File Report 2012-1008. For scale: Tokeland, WA, 35 miles away, ranks 1200 of 1211 nationally for growth, 5.19 ft/yr, 5.0x this stretch's rate. 2.1 miles up the coast, Santiago, WA shows 1.54 ft/yr of accreting.
Not this whole stretch, just Qui-nai-elt Village itself: the Coastal Change Hazards Portal is USGS's own live version of this data.
