B−
HistoryA character grade: shown, never part of Gridley’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 Gridley’s 1.4 sits above most of its state (78% of California towns have fewer) while its 1 listings outnumber those of 51% of U.S. towns.
How sure. Graded on any two of the three inputs instead, the letter would range from C to B. The pre-1940 share is a Census survey estimate (±4.3 points). The founding year is the first post office, not a stated founding date; Wikidata gives 1905.

Tribal groups, including the Maidu people, were settled in the region when they were first encountered by Spanish and Mexican scouting expeditions in the early 18th century. In the 1850s George W. Gridley, a wool grower and grain farmer who at the time was one of the largest landowners in Butte County, settled a 960-acre (390 ha) home ranch west of the town site that was to be named after him. Gridley was established in 1870 when the Oregon and California Railroad was constructed north from Marysville. The railroad reached Chico on July 2, 1870. In the summer of 1891, a series of major fires "nearly swept away" much of Gridley, and the business district was nearly destroyed again by an additional fire in July 1905.
