HistoryA character grade: shown, never part of Birch Bay’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 Birch Bay’s 0.0 sits below most of its state (27% of Washington towns have fewer) while its 0 listings outnumber those of 23% of U.S. towns.
How sure. Graded on any two of the three inputs instead, the letter would still be C−. The pre-1940 share (±1.6 points) is firm at this size. The founding year is the first post office, not a stated founding date.
Founding year: the first post office (other dates in Quick answers). Homes: Census ACS 2020–24.

Captains of Spanish ships from Acapulco and San Blas (Spanish west coast ports in Mexico) were in this area in 1791 and 1792 and named it Puerto del Garzon in 1791 by captain Jose Maria Narvaez. It was then renamed Birch Bay in 1792 by Archibald Menzies, a member of the Vancouver Expedition. Vancouver's two ships used Birch Bay as an anchorage for several days. Menzies noted a number of species of birch and gave the name to the bay.
