Board of Supervisors

Prior to the legislative act approving the creation of a Board of Supervisors in 1855, county matters were heard in regularly held "Courts of Sessions" with the County Judge presiding. Also in attendance were the County Clerk, the Sheriff and the District Attorney. The first "Court of Sessions" was held in June, 1853, at the first county seat in Alvarado (Alvarado later became part of Union City).

The first supervisors were appointed and the first meeting of the Board of Supervisors was held in the San Leandro Courthouse on April 2, 1855.
