Rancho Potrero de San Luis Obispo was a 3,506-acre (14.19 km2) Mexican land grant in present day San Luis Obispo County, California given in 1842 by Governor Juan Alvarado to María Concepción Boronda.[1] Potrero means "pasture" in Spanish. The grant was north of present day San Luis Obispo, and encompassed Cal Poly San Luis Obispo.[2]


The Boronda family patriarch, Manuel Boronda (1750-1826) accompanied Junípero Serra’s second expedition to Alta California. By 1790, Boronda was stationed at the Presidio of San Francisco and married Maria Gertrudis Higuera (1776-). The three sons of Manuel and Gertrudis Boronda were: José Canuto Boronda (1792-); José Eusebio Boronda (1801-) grantee of Rancho Rincon de Sanjon; and José Manuel Boronda (1803-1878), grantee of Rancho Los Laureles.

José Canuto Boronda was a soldier at Monterey and Missions San Antonio, San Miguel and San Juan Bautista. He married Francisca Castro and they had nine children. He "apparently" received the one square league Rancho Potrero de San Luis Obispo land grant in about 1842. His daughter Maria Concepcion "Chona" Boronda (1820-1906) received the patent in 1870. She married Oliver Deleissegues, a French sea captain, and after his death she married Jose Maria Munoz in 1851.

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 Potrero de San Luis Obispo was filed with the Public Land Commission in 1853,[3] and the grant was patented to María Concepción Boronda in 1870.[4]
