Rancho Laguna de Los Palos Colorados was a 13,316-acre Mexican land grant in present day Contra Costa County, California given in 1841 by Governor Juan Alvarado to Joaquin Moraga and his cousin, Juan Bernal. The name means "Ranch of the Lake of the Redwoods" in Spanish. The rancho included the present day Orinda, Lafayette, and Moraga, as well as the communities Canyon and Rheem. In his description of the diseño, King notes that he had in his custody the original Mexican archives, and attests that this is a "true and accurate copy."
