A final plat prepared by a Wisconsin registered land surveyor
shall be required for all subdivisions. It shall comply in all respects
with the requirements of § 236.20, Wis. Stats.
The plat shall show correctly on its face, in addition to the
information required by § 236.20, Wis. Stats., the following:
A.
Center line of streets. Exact length and bearing of the center line
of all streets.
B.
Street width. Exact street width along the line of any obliquely
intersecting street.
C.
Railroad rights-of-way. Railroad rights-of-way within and abutting
the plat.
D.
Setbacks and building lines. Setbacks or building lines required by the Plan Commission or Chapter 500, Zoning.
E.
Utilities and drainage. Utility and/or drainage easements.
F.
Future public acquisition and reservations. All lands reserved for
future public acquisition or reserved for the common use of property
owners within the plat.
G.
Special restrictions. Special restrictions required by the Plan Commission
relating to conservation easements, access control along public ways,
delineation of floodplain and wetland limits, natural resource mitigation
areas, or to the provision of landscape buffer yard easements.
H.
Floodplain limits. Floodplain limits and the contour lines lying
a vertical distance of two feet above the elevation of the one-hundred-year
recurrence interval flood or, where such data is not available, five
feet above the elevation of the maximum flood of record.
I.
Water elevations of all lakes, ponds, streams, flowages and wetlands.
Water elevations of all lakes, ponds, streams, flowages, and wetlands
at the date of the survey and approximate high and low water elevations,
all referred to National Geodetic Datum of 1929 (mean sea level).
J.
Town Zoning Administrator may require additional information. Where
the Town Zoning Administrator finds that, in order to review the final
plat, additional information is required relative to a particular
problem presented by a proposed development, the Town Zoning Administrator
shall have the authority to request in writing such information from
the subdivider or condominium developer (as applicable).
K.
Additional information may be required by others. Any additional
information required by the Plan Commission, Town Engineer, or Town
Board.
A.
The following documents shall be submitted with the final plat as
required:
(1)
Declaration
of deed restrictions and protective covenants. Submission to the Plan
Commission of the final draft of declaration of deed restrictions
and protective covenants whereby the subdivider or condominium developer
(as applicable) intends to regulate land use in the proposed subdivision
and otherwise protect the proposed development.
(2)
Conservation
easements. The submission to the Plan Commission of the final draft
of conservation easements whereby the subdivider or condominium developer
(as applicable) intends to regulate the protection of natural resource
features in the proposed subdivision in conjunction with the natural
resource protection plan.
(3)
Wisconsin
nonprofit membership corporation (homeowners' association). The submission
to the Plan Commission of the final draft of the legal instruments
and rules for any proposed Wisconsin nonprofit membership corporation
(homeowners' association) when the subdivider or condominium developer
(as applicable) proposes that property within a subdivision would
be either owned or maintained by such an organization of property
owners or a subunit of the Town pursuant to § 236.293, Wis.
Stats., whereby the subdivider or condominium developer (as applicable)
intends to regulate land use in the proposed subdivision and otherwise
protect the proposed development.
B.
Town Attorney review. The Town Attorney shall review all final declaration
of deed restrictions and protective covenants, conservation easements,
and homeowners' associations and shall approve said final instruments
as to form.
The Town Engineer shall examine all final plats within the Town
and cause to be made by a registered land surveyor, as directed by
the Town Engineer, field checks for the accuracy and closure of survey,
the proper kind and location of monuments, and the legibility and
completeness of the drawing. In addition:
A.
Maximum error of closure. Maximum error of closure before adjustment
of the survey of the exterior boundaries of the subdivision shall
not exceed, in horizontal distance or position, the ratio of one part
in 10,000, nor in azimuth four seconds of arc per interior angle.
If field measurements exceed this maximum, new field measurements
shall be made until a satisfactory closure is obtained. When a satisfactory
closure of the field measurements has been obtained, the survey of
the exterior boundary shall be adjusted to form a closed geometric
figure.
B.
Street, block, and lot dimensions. All street, block, and lot dimensions
shall be computed as closed geometric figures based upon the control
provided by the closed exterior boundary survey. If field checks disclose
an error for any interior line of the plat greater than the ratio
of one part in 5,000, or an error in measured angle greater than one
minute of arc for any angle where the shorter side forming the angle
is 300 feet or longer, necessary corrections shall be made. Where
the shorter side of a measured angle is less than 300 feet in length,
the error shall not exceed the value of one minute multiplied by the
quotient of 300 divided by the length of the shorter side; however,
such error shall not in any case exceed five minutes of arc.
C.
Town Plan Commission receipt of results of Town Engineer's examination.
The Plan Commission shall receive the results of the Town Engineer's
examination prior to recommending approval of the final plat to the
Town Board.
All final plats shall meet all the surveying and monumenting
requirements of § 236.15, Wis. Stats.
Where the plat is located within a United States Public Land
Survey quarter-section, the corners of which have been relocated or
monumented by the Southeastern Wisconsin Regional Planning Commission
(SEWRPC), county, or municipality, the final plat shall be tied directly
to one of the section or quarter-corners so relocated and monumented.
A.
Grid bearing and distance of tie determined by field measurements.
The exact grid bearing and distance of such tie shall be determined
by field measurements, and the material and Wisconsin state plane
coordinates of the monument marking the relocated section or quarter-corner,
to which the plat is tied, shall be indicated on the plat.
B.
Closed survey required. The grid bearing and distance of the tie
shall be determined by a closed survey meeting the error of closure
herein specified for the survey of the exterior boundaries of the
subdivision.
C.
Reference to the Wisconsin Coordinate System. All distances and bearings
shall be referenced directly to the Wisconsin Coordinate System and
adjusted to the county's control survey.
All final plats shall provide all the certificates required
by § 236.21, Wis. Stats. The certificate shall contain a
description of the survey, beginning at the United States Public Land
Survey corner to which the survey is tied. In addition, the surveyor
shall certify that he has fully complied with all the provisions of
this chapter.
The final plat shall only be recorded with the County Register of Deeds after the certificates of the Wisconsin Department of Administration, of the Town Board, of the surveyor, and those certificates required by § 236.21, Wis. Stats., are placed on the face of the final plat. The final plat shall be recorded as set forth in § 340-20E of this chapter.
