Eden Township, Alameda County, California
Eden Township is a former township of Alameda County, California in the San Francisco Bay Area region, which includes the present-day cities of Hayward and San Leandro, as well as the unincorporated census-designated areas of Ashland, Castro Valley, Cherryland, Fairview, and San Lorenzo. It was created from a group of Mexican land grants that were added to Alameda County when the county was established in 1853. Today there are several public and private agencies serving the region. History The area of Eden Township comprises five land grants given by the Mexican government: Sobrante Rancho, Rancho San Leandro (given to José Joaquín Estudillo), Rancho San Lorenzo, (given to Guillermo Castro), Rancho San Lorenzito (given to Francisco and Barbara Soto), and Rancho Arroyo de la Alameda (given to José de Jesús Vallejo). In 1850, when California became a state, Eden was within Contra Costa County. In 1853, Alameda County was established from five townships of Contra Costa County, as well as Washington Township from Santa Clara county. In 1856, Eden Township was given one seat on the Alameda County board of supervisors. Eden Township was known as a major poultry producing area from the late 19th to the early 20th century. Geographic
