Wisconsin Statutes Populous Counties and Cities (Ch. 228, 229) § 229.823. Jurisdiction

A district's jurisdiction is any county with a population at the date of the district's creation of more than 150,000 that includes the principal site of a stadium that is home to a professional football team, that is a member of a league of professional football teams that have home stadiums in at least 10 states and a collective average attendance for all league members of at least 40,000 persons per game over the 5 years immediately preceding the year in which a district is created, and that is approved by that league for use as a home stadium for that professional football team. Once created, the district's jurisdiction remains fixed even if population or attendance figures subsequently decline below the minimums described in this section.
