66.0701(1)(1) Except as provided in s. 66.0721, in addition to other methods provided by law, the governing body of a town, village or 2nd, 3rd or 4th class city may, by ordinance, provide that the cost of installing or constructing any public work or improvement shall be charged in whole or in part to the property benefited, and make an assessment against the property benefited in the manner that the governing body determines. The special assessment is a lien against the property from the date of the levy.

66.0701(2)(2) Every ordinance under this section shall contain provisions for reasonable notice and hearing. Any person against whose land a special assessment is levied under the ordinance may appeal in the manner prescribed in s. 66.0703 (12) within 40 days of the date of the final determination of the governing body.

66.0703(1)(a)(a) Except as provided in s. 66.0721, as a complete alternative to all other methods provided by law, any city, town or village may, by resolution of its governing body, levy and collect special assessments upon property in a limited and determinable area for special benefits conferred upon the property by any municipal work or improvement; and may provide for the payment of all or any part of the cost of the work or improvement out of the proceeds of the special assessments.

66.0703(1)(b)(b) The amount assessed against any property for any work or improvement which does not represent an exercise of the police power may not exceed the value of the benefits accruing to the property. If an assessment represents an exercise of the police power, the assessment shall be upon a reasonable basis as determined by the governing body of the city, town or village.

66.0703(2)(2) The cost of any work or improvement to be paid in whole or in part by special assessment on property may include the direct and indirect cost, the resulting damages, the interest on bonds or notes issued in anticipation of the collection of the assessments, a reasonable charge for the services of the administrative staff of the city, town or village and the cost of any architectural, engineering and legal services, and any other item of direct or indirect cost that may reasonably be attributed to the proposed work or improvement. The amount to be assessed against all property for the proposed work or improvement shall be apportioned among the individual parcels in the manner designated by the governing body.

66.0703(3)(3) A parcel of land against which a special assessment has been levied for the sanitary sewer or water main laid in one of the streets that the parcel abuts is entitled to a deduction or exemption that the governing body determines to be reasonable and just under the circumstances of each case, when a special assessment is levied for the sanitary sewer or water main laid in the other street that the corner lot abuts. The governing body may allow a similar deduction or exemption from special assessments levied for any other public improvement.

66.0703(4)(4) Before the exercise of any powers conferred by this section, the governing body shall declare by preliminary resolution its intention to exercise the powers for a stated municipal purpose. The resolution shall describe generally the contemplated purpose, the limits of the proposed assessment district, the number of installments in which the special assessments may be paid, or that the number of installments will be determined at the hearing required under sub. (7), and direct the proper municipal officer or employee to make a report on the proposal. The resolution may limit the proportion of the cost to be assessed.

66.0703(5)(5) The report required by sub. (4) shall consist of:

66.0703(5)(d)(d) A statement that the property against which the assessments are proposed is benefited, if the work or improvement constitutes an exercise of the police power. If this paragraph applies, the estimates required under par. (c) shall be replaced by a schedule of the proposed assessments.

66.0703(6)(6) A copy of the report when completed shall be filed with the municipal clerk for public inspection. If property of the state may be subject to assessment under s. 66.0705, the municipal clerk shall file a copy of the report with the state agency which manages the property. If the assessment to the property of the state for a project, as defined under s. 66.0705 (2), is $50,000 or more, the state agency shall submit a request for approval of the assessment, with its recommendation, to the building commission. The building commission shall review the assessment and shall determine within 90 days of the date on which the commission receives the report if the assessment is just and legal and if the proposed improvement is compatible with state plans for the facility which is the subject of the proposed improvement. If the building commission so determines, it shall approve the assessment. No project in which the property of the state is assessed at $50,000 or more may be commenced and no contract on the project may be let without approval of the assessment by the building commission under this subsection. The building commission shall submit a copy of its determination under this subsection to the state agency that manages the property which is the subject of the determination.

66.0703(7)(a)(a) Upon the completion and filing of the report required by sub. (4), the city, town or village clerk shall prepare a notice stating the nature of the proposed work or improvement, the general boundary lines of the proposed assessment district including, in the discretion of the governing body, a small map, the place and time at which the report may be inspected, and the place and time at which all interested persons, or their agents or attorneys, may appear before the governing body, a committee of the governing body or the board of public works and be heard concerning the matters contained in the preliminary resolution and the report. The notice shall be published as a class 1 notice, under ch. 985, in the city, town or village and a copy of the notice shall be mailed, at least 10 days before the hearing or proceeding, to every interested person whose post-office address is known, or can be ascertained with reasonable diligence. The hearing shall commence not less than 10 nor more than 40 days after publication.

66.0703(8)(a)(a) After the hearing upon any proposed work or improvement, the governing body may approve, disapprove or modify, or it may rerefer the report prepared under subs. (4) and (5) to the designated officer or employee with directions to change the plans and specifications and to accomplish a fair and equitable assessment.

66.0703(8)(b)(b) If an assessment of benefits is made against any property and an award of compensation or damages is made in favor of the same property, the governing body shall assess against or award in favor of the property only the difference between the assessment of benefits and the award of damages or compensation.

66.0703(8)(c)(c) When the governing body finally determines to proceed with the work or improvement, it shall approve the plans and specifications and adopt a resolution directing that the work or improvement be carried out and paid for in accordance with the report as finally approved.
