Ocean Park, WA Coastal Erosion Rate
Shoreline change 3.8 miles north of Ocean Park, WA
Unusual good news for this stretch: the shoreline 3.8 miles north of Ocean Park, 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.
What this reading actually covers
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 Ocean Park, WA, rather than showing one arbitrary line. Segment center: 46.55, -124.06. 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 3.8 miles north of Ocean Park, WA for 25 years would add roughly 26 feet of shoreline, again assuming nothing about the local sediment supply changes.
Where this fits nationally
110 transects feed this segment's number; 0% of them individually measured retreat. USGS's confidence interval here is ±0.72 ft/yr. Sorted from fastest erosion to fastest growth across all 1211 measured segments nationally, this one lands at 1113. Source: USGS Open-File Report 2012-1008. For scale: Copalis Beach, WA, 42 miles away, ranks 1105 of 1211 nationally for growth, 0.99 ft/yr, 1.0x this stretch's rate. 3.5 miles away, Bay Center, WA is the nearest other measured stretch: also no significant trend.
