Wisconsin Statutes Public Lands, Waters and Natural Resources (Ch. 23 to 33) § 33.33. Merger, attachment, detachment

(1) Merger. Any district may be merged with a contiguous district by resolution passed by a four-fifths vote of all the members of each board of commissioners. At the next annual or special meeting, whichever occurs first, the electors and property owners shall vote on whether to ratify the merger. If a majority of the electors and property owners present and voting in each district endorse the merger, it takes effect. Following ratification, the boards of commissioners of merging districts shall act jointly until the next annual or special meeting whichever occurs first, at which time the board of the merged district shall be conformed to the requirements specified in s. 33.28. The governing body of the county, town, village or city having the largest portion by valuation within the district shall make the appointments under s. 33.28(2).

(2) Attachment. Contiguous territory may be attached to a district upon petition by the owner or motion of the commissioners.

(3) Detachment. Territory may be detached from the district following petition of the owner or motion of the commissioners. Proposals for detachment shall be considered by the commissioners, and territory may be detached upon a finding that such territory is not benefited by continued inclusion in the district. Appeals of the commissioners' decision may be taken under s. 33.26(7).
