66.0217(6)(c)1. 1. Whether the governmental services, including zoning, to be supplied to the territory could clearly be better supplied by the town or by some other village or city whose boundaries are contiguous to the territory proposed for annexation which files with the circuit court a certified copy of a resolution adopted by a two-thirds vote of the elected members of the governing body indicating a willingness to annex the territory upon receiving an otherwise valid petition for the annexation of the territory.

66.0217(6)(c)2. 2. The shape of the proposed annexation and the homogeneity of the territory with the annexing village or city and any other contiguous village or city.

66.0217(6)(d) (d) Direct annexation by unanimous approval.

66.0217(6)(d)1. 1. Upon the request of the town affected by the annexation, the department shall review an annexation under sub. (2) to determine whether the annexation violates any of the following, provided that the town submits its request to the department within 30 days of the enactment of the annexation ordinance:

66.0217(6)(d)1.a. a. The requirement under sub. (2) regarding the contiguity of the territory to be annexed with the annexing city or village.

If the department does not complete its review and send a copy of its findings within 20 days of receiving the town’s request, the effect on the town and the annexing city or village shall be the same as if the department found no violation of the requirements specified in subd. 1. If the department finds that an annexation violates any requirement specified in subd. 1., the town from which territory is annexed may, within 45 days of its receipt of the department’s findings, challenge the annexation in circuit court.

66.0217(6)(d)3. 3. If the town commences an action to challenge the annexation and the circuit court rules against the town, the town shall pay the court costs and the city’s or village’s reasonable attorney fees incurred in defending the annexation. If the town commences an action to challenge the annexation and the circuit court rules in the town’s favor and upholds the town’s challenge, the city or village shall pay the court costs and the town’s reasonable attorney fees incurred in challenging the annexation.

66.0217(7) (7) Referendum.

66.0217(7)(a)1. 1. Within 60 days after the filing of the petition under sub. (3), the common council or village board may accept or reject the petition and if rejected no further action may be taken on the petition. Acceptance may consist of adoption of an annexation ordinance. Failure to reject the petition obligates the city or village to pay the cost of any referendum favorable to annexation.

66.0217(7)(a)2. 2. If the petition is not rejected the clerk of the city or village with whom the annexation petition is filed shall give written notice of the petition by personal service or registered mail with return receipt requested to the clerk of any town from which territory is proposed to be detached and shall give like notice to any person who files a written request with the clerk. The notice shall indicate whether the petition is for direct annexation or whether it requests a referendum on the question of annexation.

66.0217(7)(a)3. 3. If the notice indicates that the petition is for a referendum on the question of annexation, the clerk of the city or village shall file the notice as provided in s. 8.37. If the notice indicates that the petition is for a referendum on the question of annexation, the town clerk shall give notice as provided in par. (c) of a referendum of the electors residing in the area proposed for annexation to be held not less than 70 days nor more than 100 days after the date of personal service or mailing of the notice required under this paragraph. If the notice indicates that the petition is for direct annexation, no referendum shall be held unless within 30 days after the date of personal service or mailing of the notice required under this paragraph, a petition conforming to the requirements of s. 8.40 requesting a referendum is filed with the town clerk as provided in s. 8.37, signed by at least 20 percent of the electors residing in the area proposed to be annexed. If a petition requesting a referendum is filed, the clerk shall give notice as provided in par. (c) of a referendum of the electors residing in the area proposed for annexation to be held not less than 70 days nor more than 100 days after the receipt of the petition and shall mail a copy of the notice to the clerk of the city or village to which the annexation is proposed. The referendum shall be held at a convenient place within the town to be specified in the notice.

66.0217(7)(b) (b) Clerk to act. If more than one town is involved, the city or village clerk shall determine as nearly as is practicable which town contains the most electors in the area proposed to be annexed and shall indicate in the notice required under par. (a) that determination. The clerk of the town so designated shall perform the duties required under this subsection and the election shall be conducted in the town as are other elections.

66.0217(7)(c) (c) Publication of notice. The notice shall be published in a newspaper of general circulation in the area proposed to be annexed on the publication day next preceding the referendum election and one week prior to that publication.

66.0217(7)(d) (d) How conducted. The referendum shall be conducted by the town election officials but the town board may reduce the number of election officials for that election. The ballots shall contain the words “For annexation” and “Against annexation” and shall otherwise conform to the provisions of s. 5.64 (2). The election shall be conducted as are other town elections in accordance with chs. 6 and 7 to the extent applicable.

66.0217(7)(e) (e) Canvass; statement to be filed. The election inspectors shall make a statement of the holding of the election showing the whole number of votes cast, and the number cast for and against annexation, attach their affidavit to the statement and immediately file it in the office of the town clerk. They shall file a certified statement of the results in the office of the clerk of each other municipality affected.

66.0217(7)(f) (f) Costs. If the referendum is against annexation, the costs of the election shall be borne by the towns involved in the proportion that the number of electors of each town within the territory proposed to be annexed, voting in the referendum, bears to the total number of electors in that territory, voting in the referendum.

66.0217(7)(g) (g) Effect. If the result of the referendum is against annexation, all previous proceedings are nullified. If the result of the referendum is for annexation, failure of any town official to perform literally any duty required by this section does not invalidate the annexation.

66.0217(8) (8) Annexation ordinance.

66.0217(8)(a) (a) An ordinance for the annexation of the territory described in the annexation petition under sub. (3) may be enacted by a two-thirds vote of the elected members of the governing body not less than 20 days after the publication of the notice of intention to circulate the petition and not later than 120 days after the date of filing with the city or village clerk of the petition for annexation or of the referendum election if favorable to the annexation. If the annexation is subject to sub. (6) the governing body shall first review the reasons given by the department that the proposed annexation is against the public interest. An ordinance under this subsection may temporarily designate the classification of the annexed area for zoning purposes until the zoning ordinance is amended as prescribed in s. 62.23 (7) (d). Before introduction of an ordinance containing a temporary classification, the proposed classification shall be referred to and recommended by the plan commission. The authority to make a temporary classification is not effective when the county ordinance prevails during litigation as provided in s. 59.69 (7).

66.0217(8)(b) (b) The ordinance may annex the territory to an existing ward or may create an additional ward.

66.0217(8)(c) (c) The annexation is effective upon enactment of the annexation ordinance. The board of school directors in a 1st class city is not required to administer the schools in any territory annexed to the city until July 1 following the annexation.

66.0217(9)(a) (a) The clerk of a city or village which has annexed territory shall file immediately with the secretary of administration a certified copy of the ordinance, certificate and plat, and shall send one copy to each company that provides any utility service in the area that is annexed. The city or village shall also file with the county clerk or board of election commissioners the report required by s. 5.15 (4) (b). The clerk shall record the ordinance with the register of deeds and file a signed copy of the ordinance with the clerk of any affected school district. Failure to file, record or send does not invalidate the annexation and the duty to file, record or send is a continuing one. The ordinance that is filed, recorded or sent shall describe the annexed territory and the associated population. The information filed with the secretary of administration shall be utilized in making recommendations for adjustments to entitlements under the federal revenue sharing program and distribution of funds under ch. 79. The clerk shall certify annually to the secretary of administration and record with the register of deeds a legal description of the total boundaries of the municipality as those boundaries existed on December 1, unless there has been no change in the 12 months preceding.

66.0217(9)(b) (b) Within 10 days of receipt of the ordinance, certificate and plat, the secretary of administration shall forward 2 copies of the ordinance, certificate and plat to the department of transportation, one copy to the department of administration, one copy to the department of revenue, one copy to the department of public instruction, one copy to the department, one copy to the department of natural resources, one copy to the department of agriculture, trade and consumer protection and 2 copies to the clerk of the municipality from which the territory was annexed.

66.0217(9)(c) (c) Any city or village may direct a survey of its present boundaries to be made, and when properly attested the survey and plat may be filed in the office of the register of deeds in the county in which the city or village is located. Upon filing, the survey and plat are prima facie evidence of the facts set forth in the survey and plat.

66.0217(10) (10) Qualifications of electors and owners; elector determination.

66.0217(10)(a) (a) Under this section, qualifications as to electors and owners shall be determined as of the date of filing a petition, except that all qualified electors residing in the territory proposed for annexation on the day of a referendum election may vote in the election. Residence and ownership shall be bona fide and not acquired for the purpose of defeating or invalidating the annexation proceedings.

66.0217(10)(b) (b) For purposes of this section, if a number of electors cannot be determined on the basis of reported election statistics, the number shall be determined in accordance with s. 60.74 (6).

66.0217(11) (11) Action to contest annexation.

66.0217(11)(a) (a) An action on any grounds, whether procedural or jurisdictional, to contest the validity of an annexation shall be commenced within the time after adoption of the annexation ordinance provided by s. 893.73 (2). During the action, the application of, and jurisdiction over, any county zoning in the area annexed is as provided under s. 59.69 (7).

66.0217(11)(b) (b) An action contesting an annexation shall be given preference in the circuit court. The court and the parties are encouraged to consider the application of s. 802.12 to an action contesting an annexation.

66.0217(11)(c) (c) Except as provided in sub. (6) (d) 2., no action on any grounds, whether procedural or jurisdictional, to contest the validity of an annexation under sub. (2), may be brought by any town.

66.0217(12) (12) Validity of plats. If an annexation is declared invalid but before the declaration and subsequent to the annexation a plat is submitted and is approved as required in s. 236.10 (1) (a), the plat is validly approved despite the invalidity of the annexation.

66.0217(13) (13) Effective date of annexations. Because the creation of congressional, legislative, supervisory and aldermanic districts of equal population is a matter of statewide concern, any annexation action that affects a tract of land that is the subject of an ordinance enacted or resolution adopted by any city during the period from January 1, 1990, to April 1, 1991, or any later date, expressing an intent to not exercise the city’s authority to annex territory before April 1, 1991, or the specified later date, taken by a municipality during the period beginning on April 1 of the year commencing after each federal decennial census of population and ending on June 30 of the year commencing after that census, is effective on July 1 of the year commencing after that census or at such later date as may be specified in the annexation ordinance. This subsection first applies to annexations effective after March 31, 1991.

66.0217 Annotation In ascertaining whether a petition for annexation under sub. (2) (a) [now sub. (3) (a)] has been signed by the “owners of one-half of the land” in the proposed area of attachment, acreage within the territory constituting public streets and alleys is not to be taken into account in determining the sufficiency of the petition, no matter how owned or by whom. International Paper Co. v. City of Fond du Lac, 50 Wis. 2d 529, 184 N.W.2d 834 (1971).

66.0217 Annotation An annexation ordinance is not void simply because it divides the town into two parts. Town of Waukechon v. City of Shawano, 53 Wis. 2d 593, 193 N.W.2d 661 (1972).

66.0217 Annotation Although city limits did not extend the full width of a city-owned road, property on the other side was contiguous. When the boundaries of the parcel to be annexed were drawn by the petitioning landowners, the city could not be charged with arbitrary action. Town of Lyons v. City of Lake Geneva, 56 Wis. 2d 331, 202 N.W.2d 228 (1972).

66.0217 Annotation When property owners, in petitioning for annexation, divide a tract so as to control one parcel by property owners and the other by population, the two resulting annexations are valid. Town of Waukesha v. City of Waukesha, 58 Wis. 2d 525, 206 N.W.2d 585 (1973).
