Multiple settlements comprise what now is the present-day City of Saginaw. On the west side of the river the first settlement around what had been Fort Saginaw developed into Saginaw, which was incorporated as the City of Saginaw in 1857 and contained the seat of Saginaw County government. On the east side of the river a parallel settlement, East Saginaw, developed which was incorporated first as a village in 1855, and then as a city in 1859. Also south of the City of East Saginaw on the east bank of the river the village of Salina formed. Its name relates to the salty brine that led to a growing industry of salt production in the area. Both Saginaw and East Saginaw quickly became a hub for railroad transportation in addition to ships on the Saginaw River. Also on the east side of the river was Florece, another sawmill settlement, that was eventually absorbed into Saginaw.
