What drives Pacific’s History grade
On its age, its old homes and the National Register, Pacific is more historic than 9% of U.S. towns, #239 of 285 in Washington. Its National Register listings hold the grade up; its age pulls it down.
D
HistoryA character grade: shown, never part of Pacific’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 Pacific’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 D. The pre-1940 share (±2.9 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.

What stands out about Pacific’s past
Read from the archive, the National Register and the record. The page puts what stands out first.
Pacific was platted on April 10, 1906, by real estate promoter Clarence Dayton Hillman as "C.D. Hillman's Pacific City Addition to the City of Seattle". The development would take advantage of the nearby Puget Sound Electric Railway, which provided connections to Seattle and Tacoma. It was officially incorporated as a town on August 10, 1909.
In 1995, it annexed a portion of unincorporated Pierce County.
Record-breaking rains in November 2006 pushed the White River over its river banks along Pacific City Park, creating a temporary 25-acre (100,000 m2) lake.
