Chapter 66

66.0827(5) (5) 

66.0827(5)(a) (a) If a town board establishes a utility district under this section the board may, if a town sanitary district is in existence for the town, dissolve the sanitary district. If the sanitary district is dissolved, all assets, liabilities and functions of the sanitary district shall be taken over by the utility district.

66.0827(5)(b) (b) All functions performed by a sanitary district and assumed by a utility district under this subsection remain subject to regulation by the public service commission as if no transfer had occurred.

66.0827(5)(c) (c) If a sanitary district is located in more than one municipality, action under this section may be taken only upon approval of a majority of the members of the governing body of each municipality in which the sanitary district is located.

66.0827(6) (6) If a municipality within which a utility district is located is consolidated with another municipality which provides the same or similar services for which the district was established, but on a municipality-wide basis rather than on a utility district basis as provided in this section, the fund of the utility district becomes part of the general fund of the consolidated municipality and the utility district terminates. This section applies to consolidations completed prior to, on and after June 30, 1965.

66.0827 Annotation Funds raised for utility districts under this section are property taxes subject to municipal levy limits under s. 66.0602. Wisconsin Property Taxpayers, Inc. v. Town of Buchanan, 2023 WI 58, 408 Wis. 2d 287, 992 N.W.2d 100, 22-1233. See also Wisconsin Manufacturers & Commerce, Inc. v. Village of Pewaukee, 2024 WI App 23, 411 Wis. 2d 622, 5 N.W.3d 949, 23-0690.

66.0827 Annotation This section authorizes “taxation of the property in the district,” which is merely another way of saying a property tax. Nothing in this section authorizes the imposition of a taxation amount free from the restrictions imposed under other statutes broadly applicable to property taxation. The imposition of property taxes to fund a public improvement under this section must follow the procedures outlined in ch. 70 that apply to all property taxes in this state. Wisconsin Property Taxpayers, Inc. v. Town of Buchanan, 2023 WI 58, 408 Wis. 2d 287, 992 N.W.2d 100, 22-1233.

66.0827 Annotation A utility district established under this section is not a taxation district under s. 70.045, which means the utility district may not impose property taxes at all; only the municipality may do so. Although a town may establish a utility district, the town itself levies the taxes to fund the district; the town later allocates the funds raised to the utility district. Wisconsin Property Taxpayers, Inc. v. Town of Buchanan, 2023 WI 58, 408 Wis. 2d 287, 992 N.W.2d 100, 22-1233.

66.0829 66.0829 Parking systems.

66.0829(1) (1) A city, village or town may purchase, acquire, rent from a lessor, construct, extend, add to, improve, conduct, operate or rent to a lessee a municipal parking system for the parking of vehicles, including parking lots and other parking facilities, upon its public streets or roads or public grounds and issue revenue bonds to acquire funds for any one or more of these purposes. The parking lots and other parking facilities may include space designed for leasing to private persons for purposes other than parking. The provisions of s. 66.0621 governing the issuance of revenue bonds apply, to the extent applicable, to revenue bonds issued under this subsection. The municipal parking systems are public utilities under article XI, section 3, of the constitution. Principal and interest of revenue bonds issued under this subsection are payable solely from the revenues to be derived from the parking system, including without limitation revenues from parking meters or other parking facilities. Any revenue derived from a facility financed by a revenue bond issued under this subsection may be used only to pay the principal and interest of that revenue bond, except that after the principal and interest of that revenue bond have been paid in full the revenue derived from the facility may be used for any purpose.

66.0829(2) (2) Any part of a parking system under sub. (1) may be financed and operated in the following manner:

66.0829(2)(a) (a) The cost of constructing any parking system or facility, including the cost of the land, may be assessed against a benefited area, the benefited area and assessments to be determined in the manner prescribed by either subch. II of ch. 32 or s. 66.0703, except that the number of annual installments in which the assessment is payable may not exceed 20.

66.0829(2)(b) (b) The cost of operating and maintaining any parking system or facility may be assessed not more than once in each calendar year against all property in a benefited area, the area and assessments to be determined in the manner prescribed by either subch. II of ch. 32 or by s. 66.0703. The costs may include a payment in lieu of taxes, operating, maintenance and replacement costs, and interest on any unpaid capital cost.

66.0829(2)(c) (c) The governing body may, in determining the amount of the assessment under par. (a) or (b), credit any portion of the revenues from the parking system or facility.

66.0829(2)(d) (d) No assessment authorized in par. (a) or (b) may be made against any property used wholly for residential purposes.

66.0829 History History: 1973 c. 172; 1983 a. 192; 1983 a. 207 s. 93 (3); 1983 a. 236 ss. 7, 13; 1985 a. 231; 1987 a. 152; 1993 a. 246; 1997 a. 56; 1999 a. 150 s. 232; Stats. 1999 s. 66.0829.

66.0831 66.0831 Interference with public service structure. A contractor with a contract for work upon, over, along or under a public street or highway may not interfere with, destroy or disturb the structures of a public utility, including a telecommunications carrier as defined in s. 196.01 (8m), encountered in the performance of the work in a manner that interrupts, impairs or affects the public service for which the structures may be used, without first obtaining written authority from the commissioner of public works or other appropriate authority. A public utility, if given reasonable notice by the contractor of the need for temporary protection of, or a temporary change in, the utility’s structures, determined by the commissioner of public works or other appropriate authority to be reasonably necessary to enable the work, shall temporarily protect or change its structures located upon, over, along or under the surface of a public street or highway. The contractor shall pay or assure to the public utility the reasonable cost of the temporary structure or change, unless the public utility is otherwise liable. If work is done by or for the state or by or for any county, city, village, town sanitary district, metropolitan sewerage district created under ss. 200.01 to 200.15 or 200.21 to 200.65 or town, the cost of the temporary protection or temporary change shall be borne by the public utility.

66.0831 History History: 1973 c. 277; 1983 a. 296, 538; 1993 a. 496; 1999 a. 150 s. 116; Stats. 1999 s. 66.0831.

66.0831 Cross-reference Cross-reference: See also s. PSC 185.16, Wis. adm. code.

66.0831 Annotation Interference without written authority is prohibited only if the parties cannot agree that requested changes are reasonably necessary. A town sanitary district is not a town under the cost provision of this section. Wisconsin Gas Co. v. Craig D. Lawrenz & Associates, 72 Wis. 2d 389, 241 N.W.2d 384 (1976).

subch. IX of ch. 66 SUBCHAPTER IX

PUBLIC WORKS AND PROJECTS

66.0901 66.0901 Public works, contracts, bids.

66.0901(1)(am) (am) “Labor organization” has the meaning given in s. 5.02 (8m).

66.0901(1)(as) (as) “Municipality” means the state or a town, city, village, school district, board of school directors, sewer district, drainage district, technical college district or other public or quasi-public corporation, officer, board or other public body charged with the duty of receiving bids for and awarding any public contracts.

66.0901(1)(b) (b) “Person” means an individual, partnership, association, limited liability company, corporation or joint stock company, lessee, trustee or receiver.

66.0901(1)(d) (d) “Subcontractor” means a person whose relationship to the principal contractor is substantially the same as to a part of the work as the latter’s relationship is to the proprietor. A “subcontractor” takes a distinct part of the work in a way that the “subcontractor” does not contemplate doing merely personal service.

66.0901(1m) (1m) Method of bidding.

66.0901(1m)(a) (a) Except when necessary to secure federal aid, whenever a political subdivision lets a public contract by bidding, the political subdivision shall comply with all of the following:

66.0901(1m)(a)1. 1. The bidding shall be on the basis of sealed competitive bids.

66.0901(1m)(a)2. 2. The contract shall be awarded to the lowest responsible bidder.

66.0901(1m)(b) (b) Except when necessary to secure federal aid, a political subdivision may not use a bidding method that gives preference based on the geographic location of the bidder or that uses criteria other than the lowest responsible bidder in awarding a contract.

66.0901(2) (2) Bidder’s proof of responsibility. A municipality intending to enter into a public contract may, before delivering any form for bid proposals, plans, and specifications to any person, except suppliers, and others not intending to submit a direct bid, require the person to submit a full and complete statement sworn to before an officer authorized by law to administer oaths. The statement shall consist of information relating to financial ability, equipment, experience in the work prescribed in the public contract, and other matters that the municipality requires for the protection and welfare of the public in the performance of a public contract. The statement shall be in writing on a standard form of a questionnaire that is adopted and furnished by the municipality. The statement shall be filed in the manner and place designated by the municipality. The statement shall not be received less than 5 days prior to the time set for the opening of bids. The contents of the statement shall be confidential and may not be disclosed except upon the written order of the person furnishing the statement, for necessary use by the public body in qualifying the person, or in cases of actions against, or by, the person or municipality. The governing body of the municipality or the committee, board, or employee charged with, or delegated by the governing body with, the duty of receiving bids and awarding contracts shall properly evaluate the statement and shall find the maker of the statement either qualified or unqualified.

66.0901(3) (3) Proof of responsibility, condition precedent. No bid shall be received from any person who has not submitted the statement as provided in sub. (2), provided that any prospective bidder who has once qualified to the satisfaction of the municipality, committee, board or employee, and who wishes to become a bidder upon subsequent public contracts under the same jurisdiction, need not separately qualify on each public contract unless required so to do by the municipality, committee, board or employee.

66.0901(4) (4) Rejection of bids. If the municipality, committee, board or employee is not satisfied with the sufficiency of the answer contained in the statement provided under sub. (2), the municipality, committee, board or employee may reject or disregard the bid.

66.0901(5) (5) Corrections of errors in bids. If a person submits a bid or proposal for the performance of public work under any public contract to be let by a municipality and the bidder claims that a mistake, omission or error has been made in preparing the bid, the bidder shall, before the bids are opened, make known the fact that an error, omission or mistake has been made. If the bidder makes this fact known, the bid shall be returned to the bidder unopened and the bidder may not bid upon the public contract unless it is readvertised and relet upon the readvertisement. If a bidder makes an error, omission or mistake and discovers it after the bids are opened, the bidder shall immediately and without delay give written notice and make known the fact of the mistake, omission or error which has been committed and submit to the municipality clear and satisfactory evidence of the mistake, omission or error and that it was not caused by any careless act or omission on the bidder’s part in the exercise of ordinary care in examining the plans or specifications and in conforming with the provisions of this section. If the discovery and notice of a mistake, omission or error causes a forfeiture, the bidder may not recover the moneys or certified check forfeited as liquidated damages unless it is proven before a court of competent jurisdiction in an action brought for the recovery of the amount forfeited, that in making the mistake, error or omission the bidder was free from carelessness, negligence or inexcusable neglect.

66.0901(6) (6) Separation of contracts; classification of contractors. In public contracts for the construction, repair, remodeling or improvement of a public building or structure, other than highway structures and facilities, a municipality may bid projects based on a single or multiple division of the work. Public contracts shall be awarded according to the division of work selected for bidding. Except as provided in sub. (6m), the municipality may set out in any public contract reasonable and lawful conditions as to the hours of labor, wages, residence, character and classification of workers to be employed by any contractor, classify contractors as to their financial responsibility, competency and ability to perform work and set up a classified list of contractors. The municipality may reject the bid of any person, if the person has not been classified for the kind or amount of work in the bid.

66.0901(6m) (6m) Prohibited practices. A municipality may not do any of the following in a specification for bids for a public contract under this section:

66.0901(6m)(a) (a) Require that a bidder enter into or adhere to an agreement with a labor organization.

66.0901(6m)(b) (b) Consider as a factor in making an award under this section whether any bidder has or has not entered into an agreement with a labor organization.

66.0901(6m)(c) (c) Require that a bidder enter into, adhere to, or enforce any agreement that requires, as a condition of employment, that the bidder or bidder’s employees become or remain members of, or be affiliated with, a labor organization or pay any dues, fees, assessments, or other charges or expenses of any kind or amount, or provide anything of value, to a labor organization or a labor organization’s health, welfare, retirement, or other benefit plan or program.

66.0901(6s) (6s) Protected activity. Nothing in this section prohibits employers or employees from entering into agreements or engaging in any other activity protected by the National Labor Relations Act, 29 USC 151 to 169.

66.0901(7) (7) Bidder’s certificate. When bidding on a public contract, the bidder shall incorporate and make a part of the bidder’s proposal for doing any work or labor or furnishing any material in or about any public work or contract of the municipality a sworn statement by the bidder, or if not an individual by one authorized, that the bidder or authorized person has examined and carefully prepared the proposal from the plans and specifications and has checked the same in detail before submitting the proposal or bid to the municipality. As a part of the proposal, the bidder also shall submit a list of the subcontractors the bidder proposes to contract with and the class of work to be performed by each. In order to qualify for inclusion in the bidder’s list a subcontractor shall first submit a bid in writing, to the general contractor at least 48 hours prior to the time of the bid closing. The list may not be added to or altered without the written consent of the municipality. A proposal of a bidder is not invalid if any subcontractor and the class of work to be performed by the subcontractor has been omitted from a proposal; the omission shall be considered inadvertent or the bidder will perform the work personally.

66.0901(8) (8) Settlement of disputes; defaults. Whenever there is a dispute between a contractor or surety or the municipality as to whether there is compliance with the provisions of a public contract as to the hours of labor, wages, residence, character and classification of workers employed by the contractor, the determination of the municipality is final. If a violation of these provisions occurs, the municipality may declare the contract in default and request the surety to perform or relet upon advertisement the remaining portion of the public contract.

66.0901(9) (9) Estimates and release of funds.

66.0901(9)(a) (a) Notwithstanding sub. (1) (as), in this subsection, “municipality” does not include the department of transportation.

66.0901(9)(b) (b) As the work progresses under a contract involving $1,000 or more for the construction, execution, repair, remodeling or improvement of a public work or building or for the furnishing of supplies or materials, regardless of whether proposals for the contract are required to be advertised by law, the municipality, from time to time, shall grant to the contractor an estimate of the amount and proportionate value of the work done, which entitles the contractor to receive the amount of the estimate, less the retainage, from the proper fund. The retainage shall be an amount equal to not more than 5 percent of the estimate until 50 percent of the work has been completed. At 50 percent completion, further partial payments shall be made in full to the contractor and no additional amounts may be retained unless the architect or engineer certifies that the job is not proceeding satisfactorily, but amounts previously retained shall not be paid to the contractor. At 50 percent completion or any time after 50 percent completion when the progress of the work is not satisfactory, additional amounts may be retained but the total retainage may not be more than 10 percent of the value of the work completed. Upon substantial completion of the work, an amount retained may be paid to the contractor. When the work has been substantially completed except for work which cannot be completed because of weather conditions, lack of materials or other reasons which in the judgment of the municipality are valid reasons for noncompletion, the municipality may make additional payments, retaining at all times an amount sufficient to cover the estimated cost of the work still to be completed or may pay out the entire amount retained and receive from the contractor guarantees in the form of a bond or other collateral sufficient to ensure completion of the job. For the purposes of this section, estimates may include any fabricated or manufactured materials and components specified, previously paid for by the contractor and delivered to the work or properly stored and suitable for incorporation in the work embraced in the contract.

66.0901(11) (11) Limitation on performance of private construction work by political subdivisions.

66.0901(11)(a) (a) In this subsection, “construction project” means a road, sewer, water, stormwater, wastewater, grading, parking lot, or other infrastructure-related project or the provision of construction-related services for such a project.

66.0901(11)(b) (b) Except for work ancillary to replacing a utility-side water service line, as defined in s. 196.372 (1) (c), containing lead that is performed with the consent of a private property owner and that does not involve replacing the customer-side water service line, as defined in s. 196.372 (1) (a), containing lead, a political subdivision may not use its own workforce to perform a construction project for which a private person is financially responsible.

66.0901(12) (12) Public building plan information.

66.0901(12)(a) (a) In this subsection:

66.0901(12)(a)1. 1. “Public building plan information” means construction plans, designs, specifications, and related materials for construction work undertaken, or proposed to be undertaken, by a municipality pursuant to a public contract.

66.0901(12)(a)2. 2. “Public plan room” means a nonprofit organization that gathers and makes available to the public for inspection and copying public building plan information.

66.0901(12)(b) (b) Notwithstanding s. 19.35 (3), if a municipality receives a request for public building plan information from a public plan room, the municipality shall provide the requested information by electronic copy, and without charging a fee, if all of the following apply:

66.0901(12)(b)1. 1. The public building plan information relates to a structure or building constructed, or proposed to be constructed, by a municipality.

66.0901(12)(b)2. 2. The public plan room allows the public to register and inspect or copy the public building plan information that it obtains under this subsection without charging a fee.

66.0901(12)(c) (c) A municipality shall provide the requested information under par. (b) even if the municipality contracts with another person to assist the municipality with public contracts, related construction projects, or the management and storage of public building plan information.

66.0901 History History: 1971 c. 154; 1975 c. 390; 1983 a. 27; 1991 a. 316; 1993 a. 112, 399, 490, 491; 1999 a. 150 ss. 257, 258, 328 to 334; Stats. 1999 s. 66.0901; 1999 a. 186 s. 50; 2001 a. 103; 2003 a. 157; 2005 a. 204; 2009 a. 173; 2011 a. 32; 2015 a. 55; 2017 a. 3, 137; 2021 a. 239; 2021 a. 240 s. 30.

66.0901 Annotation Under sub. (5), a bidder has no right to withdraw its bid or demand that it be amended. Under the terms of the proposal, the commission was entitled to retain the deposit upon the plaintiff’s failure to execute the contract within ten days of the notice of award. Nelson Inc. of Wisconsin v. Sewerage Commission, 72 Wis. 2d 400, 241 N.W.2d 390 (1976).

66.0901 Annotation Acceptance of the bid is a precondition to forfeiture of the bidder’s deposit under sub. (5). Gaastra v. Village of Fairwater, 77 Wis. 2d 7, 252 N.W.2d 60 (1977).

66.0901 Annotation When a bid error was discovered after the contract was let, the dispute was governed by the arbitration clause in the contract, not by sub. (5). Village of Turtle Lake v. Orvedahl Construction, Inc., 135 Wis. 2d 385, 400 N.W.2d 475 (Ct. App. 1986).

66.0901 Annotation Sub. (5) does not contemplate bid amendment after bids are open, and municipalities do not have the authority to permit a bidder to amend its bid. The only relief available to a bidder that acknowledges a mistake, error, or omission in its bid is to request that its bid be withdrawn from consideration. James Cape & Sons Co. v. Mulcahy, 2005 WI 128, 285 Wis. 2d 200, 700 N.W.2d 243, 02-2817.

66.0901 Annotation Acceptance of a bid by a municipality is a precondition to forfeiture of a bidder’s deposit under sub. (5). The fourth sentence of sub. (5) specifically contemplates a court proceeding to determine whether a proposal guaranty should be returned to the bidder when a municipality has retained the proposal guaranty. If the bidder can show by clear and satisfactory evidence that its error, omission, or mistake was not caused by any careless act or omission in the exercise of ordinary care in examining the plans or specifications and was in conformance with the conditions of the statute, but the municipality is able to show how the bidder’s withdrawal has prejudiced or will prejudice the municipality, the bidder will have to meet the higher standard that it was free from carelessness, negligence, or inexcusable neglect to avoid forfeiture. James Cape & Sons Co. v. Mulcahy, 2005 WI 128, 285 Wis. 2d 200, 700 N.W.2d 243, 02-2817.

66.0901 Annotation A municipality has no power to enter into a contract unless the bid proposal complies with sub. (7). When a bidder submitted no statement providing any of the assurances required by sub. (7), the bid proposal did not comply with sub. (7), and the municipality had no authority to enter into a contract with the bidder based on that proposal. If there was a contract, it was void at its inception. Andrews Construction, Inc. v. Town of Levis, 2006 WI App 180, 296 Wis. 2d 89, 722 N.W. 2d 389, 04-3338.

66.0901 Annotation Police cars need not be purchased by competitive bid since they are “equipment” and not “supplies [or] material.” 66 Atty. Gen. 284.

66.0901 Annotation Municipalities may require bidders to include a list of subcontractors under sub. (7). Counties may reject a proposal for failure to include a complete list, except when omitted subcontractors themselves submitted timely, written bids to the general contractor. 76 Atty. Gen. 29.

66.0903 66.0903 Prevailing wage.

66.0903(1) (1) Definitions. In this section:

66.0903(1)(c) (c) “Hourly basic rate of pay” has the meaning given in s. 16.856 (1) (b), 2015 stats.

66.0903(1)(d) (d) “Local governmental unit” means a political subdivision of this state, a special purpose district in this state, an instrumentality or corporation of such a political subdivision or special purpose district, a combination or subunit of any of the foregoing or an instrumentality of the state and any of the foregoing.

66.0903(1)(f) (f) “Prevailing hours of labor” has the meaning given in s. 16.856 (1) (e), 2015 stats.

66.0903(1)(g) (g) “Prevailing wage rate” includes the meanings given under s. 66.0903 (1) (g), 2013 stats., and s. 16.856 (1) (f), 2015 stats.

66.0903(1)(h) (h) “Publicly funded private construction project” means a construction project in which the developer, investor, or owner of the project receives direct financial assistance from a local governmental unit for the erection, construction, repair, remodeling, demolition, including any alteration, painting, decorating, or grading, of a private facility, including land, a building, or other infrastructure. “Publicly funded private construction project” does not include a project of public works.

66.0903(1)(j) (j) “Truck driver” includes an owner-operator of a truck.

66.0903(1m) (1m) Statewide concern; uniformity.

66.0903(1m)(b) (b) The legislature finds that the enactment of ordinances or other enactments by local governmental units requiring laborers, workers, mechanics, and truck drivers employed on projects of public works or on publicly funded private construction projects to be paid the prevailing wage rate and to be paid at least 1.5 times their hourly basic rate of pay for hours worked in excess of the prevailing hours of labor would be logically inconsistent with, would defeat the purpose of, and would go against the repeals of s. 66.0904, 2009 stats., and s. 66.0903 (2) to (12), 2013 stats. Therefore, this section shall be construed as an enactment of statewide concern for the purposes of facilitating broader participation with respect to bidding on projects of public works, ensuring that wages accurately reflect market conditions, providing local governments with the flexibility to reduce costs on capital projects, and reducing spending at all levels of government in this state.

66.0903(1m)(c) (c) A local governmental unit may not enact and administer an ordinance or other enactment requiring laborers, workers, mechanics, and truck drivers employed on projects of public works or on publicly funded private construction projects to be paid the prevailing wage rate and to be paid at least 1.5 times their hourly basic rate of pay for hours worked in excess of the prevailing hours of labor or any similar ordinance or enactment. Any such ordinance or other enactment that is in effect on July 1, 2011, is void.

66.0903 History History: 1971 c. 154, 307; 1973 c. 181; 1977 c. 29; 1985 a. 159; 1989 a. 56, 228; 1991 a. 316; 1993 a. 112, 399; 1995 a. 27 ss. 3318, 3319, 9130 (4); 1995 a. 215; 1997 a. 3, 35; 1999 a. 70; 1999 a. 150 s. 335; Stats. 1999 s. 66.0903; 1999 a. 186 ss. 51 to 60; 2009 a. 28, 276; 2011 a. 32, 259; 2015 a. 55; 2017 a. 59.

66.0905 66.0905 Pedestrian malls.
