Senate District 5 includes all of San Joaquin County and portions of Stanislaus and Sacramento Counties. The split in Sacramento County is a result of the southern city of Galt being included in this district, while the split in Stanislaus County reflects most of the city of Modesto being added to achieve population equality, along with the whole city of Riverbank and whole communities of Del Rio and Salida. The blending in this district allows for the city of Lodi to be reunited with San Joaquin County along with its sister city of Galt. Both of these cities share a common school district and other services between cities and across counties. This district maintains the integrity of Valley floor communities and links Galt with Lodi, and the remainder of Stanislaus County with southern San Joaquin County.
