About the city: "Arroyo Grande is a city in San Luis Obispo County, California, United States. The population was 17,252 at the 2010 census.
The earliest inhabitants of the Arroyo Grande valley were Chumash Indians, who conducted extensive trade with other Native American tribes at considerable distance. A photograph appears in Jones book taken in Arroyo Grande of the last known speaker of the native Obispena Chumash language.
The first Europeans to see the area were the crew of Portuguese explorer Juan Rodríguez Cabrillo, working in the service of Spain. The Mission San Luis Obispo de Tolosa was established nearby, and agricultural activities expanded into the area. The Arroyo Grande valley was found to have particularly fertile ground, and was given the name for "wide riverbed" in Spanish.
Francis Ziba Branch, originally from New York, saw the area on a hunting expedition during the period when California was part of Mexico. Branch married María Manuela Carlón, and this marriage entitled Branch to file claim for a Mexican land grant. In 1836 he and his wife and baby son moved onto Rancho Santa Manuela. They were managing a successful cattle ranching operation when California became a U.S. territory, and then a U.S. State. But some years later they suffered financial difficulties during a drought when many cattle died. They sold off smaller parcels of land to settlers.
In 1862, the San Luis Obispo Board of Supervisors established the township of Arroyo Grande. Businesses developed along a road called Branch Street to serve local agriculture. A railroad depot was built in 1882. The city of Arroyo Grande was incorporated on July 10, 1911." (
