B−
HistoryA character grade: shown, never part of Langley’s overall grade.
Few Washington towns list much on the Register (a typical Washington town has 0.1 per 10,000 residents, the U.S. 2.4), so Langley’s 9.6 sits above most of its state (85% of Washington towns have fewer) while its 1 listings outnumber those of 51% of U.S. towns.
How sure. Graded on any two of the three inputs instead, the letter would range from C to B. The pre-1940 share is a Census survey estimate (±5.7 points). The founding year is the first post office, not a stated founding date; Wikidata gives 1913.
Founding year: the first post office (other dates in Quick answers). Homes: Census ACS 2020–24.

What stands out about Langley’s past
Read from the archive, the National Register and the record. The page puts what stands out first.
Snohomish people have inhabited south Whidbey Island for thousands of years. Langley is known in the Lushootseed language as sc̓q̓abac, meaning "gooseberry bush."
The site of Langley was a camping spot used during clam harvesting in the summer months. Nearby, there was a village of the dəgʷasx̌abš, a Snohomish band, approximately one mile east of Langley on Sandy Point (Lushootseed: č̓əč̓ɬqs). This village had a large potlatch house, which brought visitors, even as distant as the Samish, during festivities.
Nothing in the archives for these yearsWeddings on Main Street, storms, parades, school pictures, the old store. If it’s in your family album, it belongs here.
The Langley post office opened in 1891, the earliest record of the town by name (U.S. post office records). Wikidata gives 1913.
