Bay Farm Island is the name of the broad peninsula now occupied by the Oakland Airport and the southern portion of Alameda. The name originally referred to a low, sandy island within the city boundary of Alameda that now houses the central residential area of the peninsula. The salt marsh that formerly extended between this island and the mainland to its east was drained and reclaimed, turning the former island into a peninsula at the same time the former peninsula of Alameda proper was cut off from the mainland by the Tidal Canal, which connected the Oakland Estuary to San Leandro Bay.
