Alameda Creek - History

History

Five Spanish expeditions led by de Portolà, Ortega, Fages, de Anza and Amador passed over Alameda Creek between 1769 and 1795. El Camino Viejo between Pleasanton and Mission Pass crossed it near Sunol. Mission San José, in Fremont, was dedicated in 1797. The Mission thrived for 49 years until the Mexican Government's Secularization Order liquidated mission lands in 1834. Alameda Creek was the boundary of the mission lands and the 17,000-acre (69 km2) Rancho Arroyo de la Alameda granted to Jose de Jesus Vallejo, who built a flour mill near the mouth of Niles Canyon. The mill and the importance of the canyon as a passage through the hills led to growth of Niles (which in 1956 became part of Fremont, California) in the 1850s. A favorable climate, excellent soils, and a fast-growing population helped agriculture to boom. Early roads led to landings where small ships would load grain and other foodstuffs for transport to market. Completion of the Central Pacific Railroad through Niles Canyon in 1869 was essential to completion of First Transcontinental Railroad that terminated in Alameda, California that same year. The Western Pacific was also routed through Niles Canyon, connecting Sacramento, California and San Jose, California in 1906.
