C−
HistoryA character grade: shown, never part of Poway’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 Poway’s 0.0 sits below most of its state (31% of California 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 range from D to C−. The pre-1940 share (±0.5 points) is firm at this size. The founding year is the first post office, not a stated founding date.

What stands out about Poway’s past
Read from the archive, the National Register and the record. The page puts what stands out first.
The Kumeyaay people lived in the area for centuries before the Spanish colonization of the region. Artifacts such as arrowheads, spear points, metates, grinding stones, and pottery found along the bed of Poway Creek all indicate an early Kumeyaay presence. Various pictographs adorn many of Poway's boulders, and modern dating techniques suggest these paintings date to the 16th century and earlier.
The Poway post office opened in 1870, the earliest record of the town by name (U.S. post office records).
