HistoryA character grade: shown, never part of Pacifica’s overall grade.
Few California towns list much on the Register (a typical California town has 0.0 per 10,000 residents, the U.S. 2.4), so Pacifica’s 0.5 sits above most of its state (71% of California towns have fewer) while its 2 listings outnumber those of 60% of U.S. towns.
How sure. Graded on any two of the three inputs instead, the letter would range from D to C+. The pre-1940 share (±0.9 points) is firm at this size. Two sources give 1957.
