“Binder course” means the non-surface-level course that is attached to the packed-level gravel course.
“Land disturbing activity” means any man-made alteration of the land surface resulting in a change in the topography or existing vegetative or nonvegetative soil cover that may result in runoff and lead to an increase in soil erosion and movement of sediment into waters of this state. “Land disturbing activity” includes clearing and grubbing, demolition, excavating, pit trench dewatering, filling, and grading activities.
“Total cost to complete a public improvement” includes the cost to make and install storm water facilities. “Total cost to complete a public improvement” does not include any of the following:
Any fees charged by the governing body of the town or municipality.
Land disturbing activities that are necessary to achieve the desired subgrade for public improvements.
As a further condition of approval, the governing body of the town or municipality within which the subdivision lies may require that the subdivider make and install any public improvements reasonably necessary or that the subdivider provide security to ensure that the subdivider will make those improvements within a reasonable time. The governing body may not require the subdivider to provide security at the commencement of a project in an amount that is more than 120 percent of the estimated total cost to complete the required public improvements, as determined under subd. 1d.
The subdivider may construct the project in such phases as the governing body of the town or municipality approves, which approval may not be unreasonably withheld. If the subdivider's project will be constructed in phases, the amount of security required by the governing body under subd. 1. a.
is limited to the phase of the project that is currently being constructed. The governing body may not require that the subdivider provide any security for improvements sooner than is reasonably necessary before the commencement of the installation of the improvements.
If the governing body of the town or municipality requires a subdivider to provide security under subd. 1. a.
, the governing body may not require the subdivider to provide the security for more than 14 months after the date the public improvements for which the security is provided are substantially completed and upon substantial completion of the public improvements, the amount of the security the subdivider is required to provide may be no more than an amount equal to the total cost to complete any uncompleted public improvements plus 10 percent of the total cost of the completed public improvements.
This paragraph applies to all preliminary and final plats, regardless of whether submitted for approval before, on, or after August 1, 2014.
The estimated total cost to complete the required public improvements under subd. 1.
shall be determined as follows:
A governing body of the town or municipality may provide an initial estimate to the subdivider of the estimated total cost to complete the required public improvements. If the subdivider accepts the initial estimate, then the initial estimate is the estimated total cost to complete the required public improvements.
If the governing body of the town or municipality does not provide an initial estimate to the subdivider or the subdivider rejects the initial estimate, the subdivider shall provide the governing body with a bona fide bid from the subdivider's contractor to complete the required public improvements in the event of a default. If the governing body accepts the subdivider's bona fide bid, the bona fide bid is the estimated total cost to complete the required public improvements.
If the governing body of the town or municipality rejects the subdivider's bona fide bid, the governing body shall provide the subdivider with an estimate for the cost to complete the public improvements in the event of a default. If the governing body's estimate does not exceed the subdivider's bona fide bid by more than 10 percent, the governing body's estimate is the estimated total cost to complete the required public improvements. If the governing body's estimate exceeds the subdivider's bona fide bid by 10 percent or more, the estimated total cost to complete the required public improvements is the amount agreed upon by the subdivider's engineer and the governing body's engineer.
If the governing body of the town or municipality requires a subdivider to provide security under subd. 1. a.
, the governing body shall accept a performance bond or a letter of credit, or any combination thereof, at the subdivider's option, to satisfy the requirement.
The subdivider and the governing body of the town or municipality may agree that all or part of the requirement to provide security under subd. 1. a.
may be satisfied by a performance bond provided by the subdivider's contractor that names the town or municipality as an additional obligee provided that the form of the contractor's performance bond is acceptable to the governing body of the town or municipality.
Unless the governing body of a town or municipality demonstrates that a bond form does not sufficiently ensure performance in the event of default, the governing body of the town or municipality shall accept a performance bond under this subdivision if the person submitting the performance bond demonstrates that the performance bond is consistent with a standard surety bond form used by a company that, on the date the bond is obtained, is listed as an acceptable surety on federal bonds in the most recent circular 570 published by the federal department of the treasury, as required under 31 CFR 223.16
, and the performance bond is issued by a surety company licensed to do business in this state.
For purposes of subd. 1.
, public improvements reasonably necessary for a project or a phase of a project are considered to be substantially completed upon the installation of the asphalt or concrete binder course on roads to be dedicated or, if the required public improvements do not include a road to be dedicated, at the time that 90 percent of the public improvements by cost are completed.
With regard to public improvements to which subd. 1.
applies, no town or municipality may enact an ordinance relating to the substantial completion of such a public improvement that is inconsistent with subd. 2.
Upon such substantial completion, any outstanding local building permits that are related to, and dependent upon, substantial completion shall be released.
The governing body of a town or municipality shall, upon a subdivider's request, issue a permit to commence construction of a foundation or any other noncombustible structure before substantial completion of a public improvement if all public improvements related to public safety are complete and the security requirement under subd. 1. a.
has been met. The subdivider may not commence work on a building until the governing body of the town or municipality approves or issues a permit for the construction of the building.
Any city or village may require as a condition for accepting the dedication of public streets, alleys or other ways, or for permitting private streets, alleys or other public ways to be placed on the official map, that designated facilities shall have been previously provided without cost to the municipality, but which are constructed according to municipal specifications and under municipal inspection, such as, without limitation because of enumeration, sewerage, water mains and laterals, storm water management or treatment facilities, grading and improvement of streets, alleys, sidewalks and other public ways, street lighting or other facilities designated by the governing body, or that a specified portion of such costs shall be paid in advance as provided in s. 66.0709
Any county, town, city or village may require as a condition of approval that the subdivider be responsible for the cost of any necessary alterations of any existing utilities which, by virtue of the platting or certified survey map, fall within the public right-of-way.
As a further condition of approval, any county, town, city or village may require the dedication of easements by the subdivider for the purpose of assuring the unobstructed flow of solar or wind energy across adjacent lots in the subdivision.
As a further condition of approval when lands included in the plat lie within 500 feet of the ordinary high-water mark of any lake, any navigable stream, or any other body of navigable water or if land in the proposed plat involves lake or navigable stream shorelands referred to in s. 236.16
, the department of natural resources, to prevent pollution of navigable waters, or the department of safety and professional services, to protect the public health and safety, may require assurance of adequate drainage areas for private on-site wastewater treatment systems and building setback restrictions, or provisions by the owner for public sewage disposal facilities for waters of the state, as defined in s. 281.01 (18)
, industrial wastes, as defined in s. 281.01 (5)
, and other wastes, as defined in s. 281.01 (7)
. The public sewage disposal facilities may consist of one or more systems as the department of natural resources or the department of safety and professional services determines on the basis of need for prevention of pollution of the waters of the state or protection of public health and safety.
No approving authority or agency having the power to approve or object to plats shall condition approval upon compliance with, or base an objection upon, any requirement other than those specified in this section.
Where more than one governing body or other agency has authority to approve or to object to a plat and the requirements of such bodies or agencies are conflicting, the plat shall comply with the most restrictive requirements.
Any person aggrieved by an objection to a plat or a failure to approve a plat may appeal therefrom as provided in s. 62.23 (7) (e) 10.
, within 30 days of notification of the rejection of the plat. For the purpose of such appeal the term “board of appeals" means an “approving authority". Where the failure to approve is based on an unsatisfied objection, the agency making the objection shall be made a party to the action. The court shall direct that the plat be approved if it finds that the action of the approving authority or objecting agency is arbitrary, unreasonable or discriminatory.
An outlot may not be used as a building site unless it is in compliance with restrictions imposed by or under this section with respect to building sites. An outlot may be conveyed regardless of whether it may be used as a building site.

(Ct. App. 1996), 95-1312
So long as any issues addressed in both a master plan and an official map are not contradictory, for purposes of sub. (1) (c), the master plan is consistent with the official map. A master plan is not inconsistent with an official map if the plan contains elements the map does not. Lake City Corp. v. City of Mequon, 207 Wis. 2d 155

As sub. (5) does not expressly designate the “appealing authority" to whom appeal papers should be directed, the appellant's service of an appeal on the county planning and development department rather than on the planning and development committee, which had made the disputed decision, was not grounds for dismissal when there had been pervasive use of department personnel and stationery in the process.

A city's extraterritorial plat condition that allowed lots of less than 20 acres only when attached to the public sanitary sewer system had the effect of requiring a public sanitary sewer system for lot sizes smaller than 20 acres, violating the ruling of Rice
that authority to condition plat approval on public improvements is granted solely to the governing body of the municipality in which the subdivision is located.
Town of Delton v. City of Baraboo, 2007 WI App 120
, 301 Wis. 2d 720
, 731 N.W.2d 308
For every subdivision of land there shall be a survey meeting the following requirements:
All of the monuments required in pars. (ag)
shall be placed flush with the ground if practicable. Whenever placement of a monument under this subsection is required at a corner or point that falls within a street or proposed future street, the monument shall be placed in the side line of the street if practicable.
The external boundaries of a subdivision shall be monumented in the field by monuments of concrete containing a ferrous rod one-fourth inch in diameter or greater imbedded its full length, not less than 18 inches in length, not less than 4 inches square or 5 inches in diameter, and marked on the top with a cross, brass plug, iron rod, or other durable material securely embedded; or by iron rods or pipes at least 18 inches long and 2 inches in diameter weighing not less than 3.65 pounds per lineal foot. Solid round or square iron bars of equal or greater length or weight per foot may be used in lieu of pipes wherever pipes are specified in this section. These monuments shall be placed at all corners, at each end of all curves, at the point where a curve changes its radius, at all angle points in any line and at all angle points along the meander line, said points to be not less than 20 feet back from the determined or approximated ordinary high water mark.
All internal boundaries and those corners and points not required to be marked by par. (ag)
shall be monumented in the field by like monuments as defined in par. (ag)
. These monuments shall be placed at all block corners, at each end of all curves, at the point where a curve changes its radius, and at all angle points in any line.
All lot, outlot, park and public access corners and the corners of land dedicated to the public shall be monumented in the field by iron pipes at least 18 inches long and one inch in diameter, weighing not less than 1.13 pounds per lineal foot, or by round or square iron bars at least 18 inches long and weighing not less than 1.13 pounds per lineal foot.
The lines of lots, outlots, parks and public access and land dedicated to the public that extend to lakes or to navigable streams shall be monumented in the field by iron pipes at least 18 inches long and one inch in diameter weighing not less than 1.13 pounds per lineal foot, or by round or square iron bars at least 18 inches long and weighing not less than 1.13 pounds per lineal foot. These monuments shall be placed at the point of intersection of the lake or navigable stream lot line with a meander line established not less than 20 feet back from the determined or approximated ordinary high water mark.
Any durable metal or concrete monuments may be used in lieu of iron pipes provided that they are uniform within the platted area and have a permanent magnet embedded near the top or bottom or both.
In cases where strict compliance with this subsection would be unduly difficult or would not provide adequate monuments, the department may make other reasonable requirements.
The governing body of the city, village or town which is required to approve the subdivision under s. 236.10
may waive the placing of monuments under pars. (b)
for a reasonable time on condition that the subdivider executes a surety bond to ensure that he or she will place the monuments within the time required.
(2) Accuracy of survey.
The survey shall be performed by a professional land surveyor and if the error in the latitude and departure closure of the survey or any part thereof is greater than the ratio of one in 3,000, the plat may be rejected.
All permanent survey monuments required by sub. (1) (a), (b), (c), and (d) must be placed in the field prior to submission of a final subdivision plat for state level review; provided, however, that in the event of a waiver under sub. (1) (h), the placement of all permanent monuments other than those required by sub. (1) (a) may be temporarily deferred. 59 Atty. Gen. 262.
Layout requirements. 236.16(1)
Minimum lot width and area.
In counties having a population of 40,000 or more, each lot in a residential area shall have a minimum average width of 50 feet and a minimum area of 6,000 square feet; in counties of less than 40,000, each lot in a residential area shall have a minimum average width of 60 feet and a minimum area of 7,200 square feet. In municipalities, towns and counties adopting subdivision control ordinances under s. 236.45
, minimum lot width and area may be reduced to dimensions authorized under such ordinances if the lots are served by public sewers.
(2) Minimum street width.
All streets shall be of the width specified on the master plan or official map or of a width at least as great as that of the existing streets if there is no master plan or official map, but no full street shall be less than 60 feet wide unless otherwise permitted by local ordinance. Widths of town roads platted after January 1, 1966, shall, however, comply with minimum standards for town roads prescribed by s. 82.50
. Streets or frontage roads auxiliary to and located on the side of a full street for service to the abutting property may not after January 1, 1966, be less than 49.5 feet wide.
(3) Lake and navigable stream shore plats; public access. 236.16(3)(a)(a)
All subdivisions abutting on a lake or a navigable stream shall provide public access at least 60 feet wide providing access to the water's edge so that there will be public access, which is connected to existing public roads, at not more than one-half mile intervals as measured along the lake or the navigable stream shore except where greater intervals and wider access is agreed upon by the department of natural resources and the department, and excluding shore areas where public parks or open-space streets or roads on either side of the navigable stream are provided.
No public access established under this chapter may be vacated except by circuit court action as provided in s. 236.43
, except that such public access may be discontinued under s. 66.1003
, subject to s. 66.1006
Except as provided in par. (d)
, this subsection does not require any local unit of government to improve land provided for public access.
All of the owners of all of the land adjacent to a public access established under par. (a)
to an inland lake, as defined in s. 30.92 (1) (bk)
, may petition the city, village, town or county that owns the public access to construct shoreline erosion control measures. Subject to par. (e)
, the city, village, town or county shall construct the requested shoreline erosion control measures or request the department of natural resources to determine the need for shoreline erosion control measures. Upon receipt of a request under this paragraph from a city, village, town or county, the department of natural resources shall follow the notice and hearing procedures in s. 30.208 (3)
. Subject to par. (e)
, the city, village, town or county shall construct shoreline erosion control measures as required by the department of natural resources if the department of natural resources determines all of the following:
Erosion is evident along the shoreline in the vicinity of the public access.
The shoreline erosion control measures proposed by the owners of the property adjacent to the public access are designed according to accepted engineering practices.
Sufficient property owners, in addition to the owners of all property adjacent to the public access, have agreed to construct shoreline erosion control measures so that the shoreline erosion control project is likely to be effective in controlling erosion at the location of the public access and its vicinity.
The shoreline erosion control project is not likely to be effective in controlling erosion at the location of the public access and its vicinity if the city, village, town or county does not construct shoreline erosion control measures on the land provided for public access.
A city, village, town or county may not be required to construct shoreline erosion control measures under par. (d)
on land other than land provided for public access.
(f) Paragraphs (b)
apply to public access that exists on, or that is established after, May 7, 1998.
(4) Lake and navigable stream shore plats; land between meander line and water's edge.
The lands lying between the meander line, established in accordance with s. 236.20 (2) (g)
, and the water's edge, and any otherwise unplattable lands which lie between a proposed subdivision and the water's edge shall be included as part of lots, outlots or public dedications in any plat abutting a lake or a navigable stream. This subsection applies not only to lands proposed to be subdivided but also to all lands under option to the subdivider or in which the subdivider holds any interest and which are contiguous to the lands proposed to be subdivided and which abut a lake or a navigable stream.
NOTE: 2003 Wis. Act 214
, which affected this section, contains extensive explanatory notes.
See also ss. NR 1.91
, Wis. adm. code.
When a strip of land was labeled on a plat “Public Access" that abutted a lake and connected to a public highway, the plat substantially met the statutory requirement of a “clear dedication to the public." While the dedication did not contain the exact formula found in s. 236.20 (4), under Hunt
, 19 Wis. 2d 113
, that is not necessary. Vande Zande v. Town of Marquette, 2008 WI App 144
, 314 Wis. 2d 143
, 758 N.W.2d 187
The circumstances under which the statutory platting standards set forth in subs. (1), (2), and (3) and 236.20 (4) (d) may be waived or varied, with specific reference to the approval of island subdivision plats, are discussed. 62 Atty. Gen. 315.
Each of 2 adjacent platted lots may not be divided for the purpose of sale or building development if the division will result in lots or parcels that do not comply with minimum lot width and area requirements established under sub. (1). Section 236.335 clearly limits the division of a lot in a recorded plat if the resulting lots or parcels do not conform to this chapter. 63 Atty. Gen. 122.
Sub. (3) does not apply to a navigable lake created by artificially enlarging a previously nonnavigable watercourse. 64 Atty. Gen. 146.
The extent to which local governments may vary the terms of ss. 236.16 (1) and (2) and 236.20 (4) (d) by ordinance is discussed. 64 Atty. Gen. 175.
Sub. (4) aims at preventing subdividers from creating narrow, unplatted buffer zones between platted lands and water's edge, thus avoiding public access requirements. 66 Atty. Gen. 85.
Wisconsin coordinate system. 236.18(1)(a)(a)
No plat that is referenced to a Wisconsin coordinate system under sub. (2)
may be recorded unless it is based on a datum that the approving authority under s. 236.10
of the jurisdiction in which the land is located has selected by ordinance.
An approving authority under s. 236.10
may select a Wisconsin coordinate system under sub. (2)
. If it does so, it shall notify the department, on a form provided by the department, of the selection.
