What drives Birch Bay’s History grade

On its age, its old homes and the National Register, Birch Bay is more historic than 20% of U.S. towns, #182 of 285 in Washington. Its age holds the grade up; its National Register listings pull it down.

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.

The story

How Birch Bay came to be

From Wikipedia’s history of Birch Bay.

Read it all →

Local indigenous communities named this place Say-wak, meaning "people saved from a flood by building a raft."

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.
