HistoryA character grade: shown, never part of Eastvale’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 Eastvale’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.
NoteThe founding year comes from Wikidata alone; no second source gives 2010.

What stands out about Eastvale’s past
Read from the archive, the National Register and the record. The page puts what stands out first.
Recorded history of land in the far western side of present-day Riverside County and north of the Santa Ana River begins in 1838, when Mexican Governor Juan Alvarado, of the Alta California territory, granted Rancho Jurupa (some 48 square miles) to Juan Bandini. The city of Eastvale now occupies approximately the westernmost one-quarter of former Rancho Jurupa land grant. The Mexican–American War between the United States and Mexico ended in 1848 with the Treaty of Guadalupe Hidalgo, by which Mexico ceded Alta California and much other Southwestern land to the US. Two years later, on September 9, 1850, California became a U.S. state.
Eastvale is among the newest of U.S. towns, #842 of 847 in California. The History grade combines the town’s founding era, the share of homes built before 1940 and its National Register listings. It’s a character grade, so it isn’t part of the overall grade. How it works.
