Gearhart, OR Coastal Erosion Rate

Shoreline change 1.9 miles north of Gearhart, OR

Accretion (beach growing)

Unusual good news for this stretch: the shoreline 1.9 miles north of Gearhart, OR has grown by a measured 3.67 feet a year on average, per USGS's long-term transect data for this section. At that rate, the shoreline has gained roughly 36.7 feet over the last decade.

What this reading actually covers

This is a roughly 3.5-mile stretch of coast, not one address or parcel - USGS's own transects run every few hundred feet, but that's finer than any one property needs, so this page reports the stretch nearest Gearhart, OR. Centered near 46.06°N, 123.93°W. 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.

25 years at this rate

Holding the 3.67 ft/yr accretion rate 1.9 miles north of Gearhart, OR for 25 years would add roughly 92 feet of shoreline, again assuming nothing about the local sediment supply changes.

Where this fits nationally

Averaging 72 separate transects produced this segment's rate, with 0% individually reading as erosion, rather than relying on any single survey line. USGS's confidence interval here is ±3.06 ft/yr. This segment ranks 1188 of 1211 measured US coastal segments, ordered from fastest erosion to fastest growth. Source: USGS Open-File Report 2012-1008.
