Tokeland, WA Coastal Erosion Rate
Shoreline change 5.7 miles northwest of Tokeland, WA
Unusual good news for this stretch: the shoreline 5.7 miles northwest of Tokeland, WA has grown by a measured 5.19 feet a year on average, per USGS's long-term transect data for this section. At that rate, the shoreline has gained roughly 51.9 feet over the last decade.
The grain of this number
Nothing here is parcel-level. USGS's raw transects run every few hundred feet along the shore; this page averages the ones nearest Tokeland, WA into one ~3.5-mile reading rather than picking a single arbitrary line to represent the area. Centered near 46.75°N, 124.09°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.
25 years at this rate
Holding the 5.19 ft/yr accretion rate 5.7 miles northwest of Tokeland, WA for 25 years would add roughly 130 feet of shoreline, again assuming nothing about the local sediment supply changes.
What backs this reading up
