Arroyo Grande History

The Chumash Indians were the first inhabitants of the Arroyo Grande valley. Spanish explorer Juan Cabrillo was the first European to visit the area. Gradually, agricultural activities started developing in the area as it proved to be extremely fertile. The area was thus named 'Arroyo Grande', which is Spanish for "wide riverbed." The San Luis Obispo Board of Supervisors set up the township of Arroyo Grande in the year 1862 and a rail depot was constructed 20 years later. The city of Arroyo Grande was officially incorporated on July 10, 1911.
