District
SENATE DISTRTICT 13 (2011)
SD 13 is based on an almost complete nesting of AD 22 and AD 24 and consists of the remainder of San Mateo County south of SD 11 and northern Santa Clara County, including the sister cities of Mountain View and Sunnyvale. This district keeps the San Mateo coastline from Pacifica to the Ano Nuevo State Reserve and peninsula cities from South San Francisco to Sunnyvale together. South San Francisco is the only city split to achieve population equality.
