History

The district was created in the 1972 redistricting act (1971 Wisc. Act 304) which first established the numbered district system, replacing the previous system which allocated districts to specific counties.^[5] The 30th district was drawn mostly in line with the boundaries of the previous Buffalo County–Pepin County–Pierce County district, exchanging part of northeast Pierce County for part of western Trempealeau County. The last representative of the Buffalo–Pepin–Pierce district, Michael P. Early, was elected in 1972 as the first representative of the 30th Assembly district.^[6]

The 1982 court-ordered redistricting briefly moved the 30th district to eastern Waukesha County. The 1983 redistricting act moved it back to western Wisconsin, but in a much smaller geographic space than 1972, comprising just Pierce County and part of southwest St. Croix County, including the cities of Hudson and River Falls. As population grew in the two cities, the 1992 court-ordered plan removed more rural parts of northeast Pierce County and central St. Croix County, but maintained the core population of the district. The 2002 redistricting continued that trend, with the district comprising just the western third of Pierce County and a strip of southwest St. Croix County. The 2011 redistricting act (2011 Wisc. Act 43) also continued with Hudson and River Falls as the core of the district, but removed most of the rest of Pierce County and shifted the district north to contain more of St. Croix County. The 2022 court-ordered redistricting severed the Hudson and River Falls connection, removing nearly all of River Falls from the district and expanding it to include much more of rural St. Croix County.

The 2024 redistricting (2023 Wisc. Act 94) restored the old Hudson and River Falls core of the district, moving it back into northwest Pierce County and southwest St. Croix County. Under the new map configuration, the 30th Assembly district is projected to be one of the most competitive districts in the state legislature.
