Newport, OR Coastal Erosion Rate
Shoreline change 2 miles north of Newport, OR
Unusual good news for this stretch: the shoreline 2 miles north of Newport, OR has grown by a measured 1.16 feet a year on average, per USGS's long-term transect data for this section. At that rate, the shoreline has gained roughly 11.6 feet over the last decade.
What "Newport" means on this page
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 Newport, OR, rather than showing one arbitrary line. Segment center: 44.65, -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 1.16 ft/yr means over time
Holding the 1.16 ft/yr accretion rate 2 miles north of Newport, OR for 25 years would add roughly 29 feet of shoreline, again assuming nothing about the local sediment supply changes.
How solid is this number
Averaging 93 separate transects produced this segment's rate, with 3% individually reading as erosion, rather than relying on any single survey line. USGS's confidence interval here is ±1.04 ft/yr. This segment ranks 1121 of 1211 measured US coastal segments, ordered from fastest erosion to fastest growth. Source: USGS Open-File Report 2012-1008. For scale: Ocean City, NJ, 2529 miles away, ranks 1162 of 1211 nationally for growth, 2.2 ft/yr, 1.9x this stretch's rate. 3.6 miles away, Newport, OR is the nearest other measured stretch: also no significant trend.
Not this whole stretch, just Newport itself: the Coastal Change Hazards Portal is USGS's own live version of this data.
