If municipal or tribal parties to a contract have varying powers or duties under the law, each may act under the contract to the extent of its lawful powers and duties. A contract under this subsection may bind the contracting parties for the length of time specified in the contract. This section shall be interpreted liberally in favor of cooperative action between municipalities and between municipalities and Indian tribes and bands in this state. If a municipality is required to establish or maintain an agency, department, commission, or any other office or position to carry out a municipal responsibility, and the municipality joins with another municipality by entering into an intergovernmental cooperation contract under this subsection to jointly carry out the responsibility, the jointly established or maintained agency, department, commission, or any other office or position to which the contract applies fulfills, subject to sub. (7), the municipality's obligation to establish or maintain such entities or positions until the contract entered into under this subsection expires or is terminated by the parties. In addition, if 2 or more municipalities enter into an intergovernmental cooperation contract and create a commission under this section to jointly or regionally administer a function or project, the commission shall be considered, subject to sub. (7), to be a single entity that represents, and may act on behalf of, the joint interests of the signatories to the contract entered into under this section.(3) Any contract under sub. (2) may provide a plan for administration of the function or project, which may include but is not limited to provisions as to proration of the expenses involved, deposit and disbursement of funds appropriated, submission and approval of budgets, creation of a commission, selection and removal of commissioners, and formation and letting of contracts.(4) A commission created by contract under sub. (2) may finance the acquisition, development, remodeling, construction and equipment of land, buildings and facilities for regional projects under s. 66.0621 .

An agreement under this subsection may include only the provisions authorized under this section and s. 66.0305 , and one or more of the following: 1. That specified boundary lines apply on the effective date of the agreement.2. That specified boundary line changes shall occur during the term of the agreement and the approximate dates by which the changes shall occur.3. That specified boundary line changes may occur during the term of the agreement and the approximate dates by which the changes may occur.4. That a required boundary line change under subd. 2. or an optional boundary line change under subd. 3. is subject to the occurrence of conditions set forth in the agreement.5. That specified boundary lines may not be changed during the term of the agreement.(b) The maximum term of an agreement under this subsection is 10 years. When an agreement expires, all provisions of the agreement expire, except that any boundary determined under the agreement remains in effect until subsequently changed.(c)1. Before an agreement under this subsection may take effect, and subject to par. (e), it must be approved by the governing body of each municipality by the adoption of a resolution. Before each municipality may adopt a resolution, each shall hold a public hearing on the agreement or both municipalities shall hold a joint public hearing on the agreement. Before the public hearing may be held, each municipality shall give notice of the pending agreement and public hearing by publishing a class 1 notice, under ch. 985, and by giving notice to each property owner whose property is currently located in that municipality and in, or immediately adjacent to, the territory whose jurisdiction will change. Notice shall be given at least 20 days before the public hearing and notice to property owners shall be made by certified mail.2. An agreement under this subsection is subject to a referendum of the electors residing within the territory whose jurisdiction is subject to change as a result of the agreement. After each municipality approves the agreement by adoption of a resolution, each municipality shall publish the agreement in the territory whose jurisdiction is subject to change as a result of the agreement as a class 1 notice, under ch. 985. A referendum shall be held if, within 30 days after the publication of the agreement, a petition for a referendum conforming to the requirements of s. 8.40 , signed by at least 20 percent of the electors residing within the territory whose jurisdiction is subject to change as a result of the agreement is filed, in accordance with s. 8.37 , with the clerk of each municipality that is a party to the agreement. The referendum shall be conducted jointly by the municipalities and shall otherwise be conducted as are annexation referenda. If the agreement is approved in the referendum, it may take effect. If the agreement is not approved in the referendum, it may not take effect.(d) An agreement under this subsection may provide that, during the term of the agreement, no other procedure for altering a municipality's boundaries may be used to alter a boundary that is affected by the agreement, except an annexation conducted under s. 281.43(1m) , regardless of whether the boundary is proposed to be maintained or changed or is allowed to be changed under the agreement. After the agreement has expired, the boundary may be altered.(e) A boundary change included in an agreement under this subsection shall be accomplished by the enactment of an ordinance by the governing body designated to do so in the agreement. The filing and recording requirements under s. 66.0217(9) (a) , as they apply to cities and villages under s. 66.0217(9) (a) , apply to municipalities under this subsection. The requirements for the secretary of administration under s. 66.0217(9) (b) , as they apply under that section, apply to the secretary of administration when he or she receives an ordinance that is filed under this subsection.(f) No action to contest the validity of an agreement under this subsection may be commenced after 60 days from the date the agreement becomes effective.(g) This subsection is the exclusive authority under this section for entering into an agreement that determines all or a portion of the common boundary line between municipalities.(h) An agreement under this section that has been entered into before January 19, 2008, that affects the location of a boundary between municipalities, is not invalid as lacking authority under this section to affect the location of the boundary.(7) With regard to a contract entered into under sub. (2) between 2 or more counties, which relates to the provision of services or facilities under a contract with an officer or agency of the state, the contract may not take effect unless it is approved in writing by the officer or chief of the agency that has authority over the contract for the provision of services or facilities. The contract must be approved or disapproved in writing by the officer or chief of the agency with regard to the matters within the scope of the contract for the provision of services or facilities within 90 days after receipt of the contract. Any disapproval shall detail the specific respects in which the proposed contract fails to demonstrate that the signatories intend to fulfill their contractual responsibilities or obligations. If the officer or chief of the agency fails to approve or disapprove of the contract entered into under sub. (2) within 90 days after receipt, the contract shall be considered approved by the officer or chief of the agency.Amended by Acts 2017 ch, 59,s 984c, eff. 9/23/2017.Amended by Acts 2017 ch, 59,s 984b, eff. 9/23/2017.Amended by Acts 2015 ch, 55,s 1969, eff. 7/14/2015.Amended by Acts 2015 ch, 55,s 1966m, eff. 7/14/2015.Amended by Acts 2013 ch, 14,s 36, eff. 6/2/2013.1999 a. 150 ss. 348, 349, 352, 353; 1999 a. 167 s. 38; 2001 a. 16, 30; 2007 a. 20, 43; 2009 a. 28, 112; 2011 a. 32. The plain language of sub. (6) does not limit the scope of boundary changes to only "modest" changes. The statutes provide multiple methods for altering municipal boundary lines. There is nothing absurd about the fact that the legislature might permit intergovernmental cooperation agreements to include major boundary changes without agency approval or a public referendum at least no more absurd than the fact that a "minor" boundary change may be accomplished without agency approval or a public referendum. City of Kaukauna v. Village of Harrison, 2015 WI App 73, 365 Wis. 2d 181, 870 N.W.2d 680, 14-2828. Sub. (6) (c) 1. does not expressly specify what information must be contained in the notices that are published and sent by certified mail. In contrast, numerous other statutes contained within ch. 66 establish specific content requirements for public notice. The legislature knows how to require specific public notice of proposed boundary changes; it chose not to do so in sub. (6) (c) 1. City of Kaukauna v. Village of Harrison, 2015 WI App 73, 365 Wis. 2d 181, 870 N.W.2d 680, 14-2828. Counties may enter into joint agreements to collectively furnish and fund nursing home services if the agreements do not violate federal and state Medicaid statutes and regulations prohibiting supplementation. Assessments resulting from such agreements that are computed without reference to and are not attributable to purchase of services contracts involving particular Medicaid patients would not be considered supplementation. Assessments that are computed with reference to or are attributable to purchase of services contracts involving particular Medicaid patients are not permissible. The validity of hybrid assessments that do not fit solely within either one of those two categories must be determined on a case-by-case basis. OAG 4-09.
