Rancho Cañada de Verde y Arroyo de la Purisima

Rancho Cañada de Verde y Arroyo de la Purísima was a 8,906-acre (36.04 km2) Mexican land grant in present-day San Mateo County, California given in 1838 by Governor Juan B. Alvarado to José María Alviso.

[1] The name roughly translates to ranch of the green glen and brook of the Purest (as in Immaculate Conception of the Virgin Mary).

[5] With the cession of California to the United States following the Mexican-American War, the 1848 Treaty of Guadalupe Hidalgo provided that the land grants would be honored.

As required by the Land Act of 1851, a claim for Rancho Cañada de Verde y Arroyo de la Purísima was filed by José Antonio Alviso with the Public Land Commission in 1852.

[6][7] An appeal by the US was rejected by the US Supreme Court,[8] and the grant was patented to José Antonio Alviso in 1865.
