The 30th district was created by the 1850 Michigan Constitution, as the 1835 constitution only permitted a maximum of eight senate districts.

However, redistricting in 2022 reconfigured the district to take in much of the northern half of the city of Grand Rapids, making it a more competitive seat.

[4] Incumbent Republican state senator Mark Huizenga, who had won a special election for the previous 28th district,[5] was narrowly re-elected over Democratic state representative David LaGrand, the closest race of the entire 2022 state Senate elections.

[6] District 30 encompasses parts of Kent and Ottawa counties.

[7] District 30, as dictated by the 2011 Apportionment Plan, was exactly coterminous with Ottawa County in the western suburbs of Grand Rapids, including the communities of Grand Haven, Hudsonville, Coopersville, Zeeland, Ferrysburg, Allendale, Jenison, Georgetown Township, Grand Haven Township, Holland Township, Park Township, Spring Lake Township, Zeeland Township, and most of northern Holland.
