History grade
What drives Palo Alto’s History grade
On its age, its old homes and the National Register, Palo Alto is more historic than 72% of U.S. towns, #47 of 847 in California. Its National Register listings hold the grade up; its age pulls it down.
B+
HistoryA character grade: shown, never part of Palo Alto’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 Palo Alto’s 60.4 sits above most of its state (98% of California towns have fewer) while its 406 historic buildings outnumber those of 96% of U.S. towns.
How sure. Graded on any two of the three inputs instead, the letter would range from C+ to A. The pre-1940 share (±1.2 points) is firm at this size. The founding year is the first post office, not a stated founding date; Wikidata’s 1894 falls in the same era, so the grade doesn’t depend on which one is used.

Before the arrival of Europeans, the Ohlone lived on the San Francisco peninsula; in particular, the Puichon Ohlone lived in the Palo Alto area. The area of modern Palo Alto was first recorded by the 1769 party of Gaspar de Portolá, a 64-man, 200-horse expedition setting out from San Diego to find Monterey Bay. The group trekked past the bay without recognizing it and continued north. When they reached modern-day Pacifica, they ascended Sweeney Ridge and saw the San Francisco Bay on November 2. Portolá descended from Sweeney Ridge southeast down San Andreas Creek to Laguna Creek (now Crystal Springs Reservoir), thence to the San Francisquito Creek watershed, ultimately camping from November 6–11, 1769, by a tall redwood later to be known as El Palo Alto.
