D−
HistoryA character grade: shown, never part of Fountain Valley’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 Fountain Valley’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 D. The pre-1940 share (±0.4 points) is firm at this size. Two sources give 1957.

The Indigenous people of the Fountain Valley area are the Tongva. The closest village to present-day site of the city was the village of Pasbenga. The village was part of a series of villages along what the Spanish would refer to as the Santa Ana River.
European settlement of the area began when Manuel Nieto was granted the land for Rancho Los Nietos, later Rancho Las Bolsas, which encompassed over 300,000 acres (1,200 km2), including present-day Fountain Valley. Control of the land was subsequently transferred to Mexico upon independence from Spain, and then to the United States as part of the Treaty of Guadalupe Hidalgo.
