A.
General requirements. A preliminary plat shall be
required for all subdivisions and shall be based upon a survey by
a registered land surveyor.
(1)
The plat shall be prepared on tracing cloth, reproducible
drafting film or paper of good quality at a map scale of not more
than 100 feet to the inch and shall show correctly on its face the
following information:
(a)
Title or name under which the proposed subdivision
is to be recorded. Such title shall not be the same or similar to
a previously recorded plat within Jefferson County unless it is an
addition to a previously recorded plat and is so stated on the plat.
(b)
Property location of a proposed subdivision
by government lot, quarter section, township, range, county and state.
(c)
Date, graphic scale and North arrow.
(d)
Names and addresses of the owner, subdivider
and land surveyor preparing the plat.
(2)
The entire area contiguous to the proposed plat owned
or controlled by the subdivider shall be included on the preliminary
plat even though only a portion of said area is proposed for immediate
development. The Council may waive this requirement where it is unnecessary
to fulfill the purposes and intent of this chapter and undue hardship
would result from strict application thereof.
B.
Plat data. All preliminary plats shall show the following:
(1)
Length and bearing of the exterior boundaries of the
proposed subdivision referenced to a corner established in U.S. Public
Land Survey and the total acreage encompassed thereby.
(2)
Existing contours at vertical intervals of not more
than two feet where the slope of the ground surface is less than 10%
and of not more than five feet where the slope of the ground surface
is 10% or more. Elevations shall be marked on such contours based
on USGS datum.
(3)
Water elevations of adjoining lakes and streams at
the date of the survey and approximate high and low water elevations,
all referred to USGS datum.
(4)
Floodplain limits and the contour line 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.
(5)
Location, right-of-way width and names of all existing
streets, alleys or other public ways, easements, railroad and utility
rights-of-way and all section and quarter section lines within the
exterior boundaries of the plat or immediately adjacent thereto.
(6)
Type, width and elevation of any existing street pavements
within the exterior boundaries of the plat or immediately adjacent
thereto together with any legally established center-line elevations,
all to USGS datum.
(7)
Location and names of any adjacent subdivisions, parks
and cemeteries, and owners of record of abutting unplatted lands.
(8)

the plat or immediately adjacent tract thereto. If no sewers or water
mains are located on or immediately adjacent to the tract, the nearest
such sewers or water mains which might be extended to serve the tract
shall be indicated by their direction and distance from the tract,
size and invert elevations.
(9)
Locations of all existing property boundary lines,
corporate limit lines, structures, drives, streams and watercourses,

in relation to the access.
(17)
Any proposed lake and stream improvement or
relocation.
C.
Grading plans and profiles. The Council, upon recommendation
of the Director of Public Works, may require that the subdivider provide
street plans and profiles showing existing ground surface and proposed
and established street grades, including extensions for a reasonable
distance beyond the limits of the proposed subdivision when requested.
All elevations shall be based upon USGS datum, and plans and profiles
shall be of sufficient detail to determine that streets will conform
to the grade of existing streets or their extension or to the established
grades of future streets and shall be subject to the approval of the
Director of Public Works.
D.
Testing. The Director of Public Works may require
that borings and soundings be made in specified areas to ascertain
subsurface soil, rock and water conditions, including depths to bedrock
and depth to groundwater table. Where the subdivision will not be
served by central sanitary sewer service, the provisions of Ch. COMM
85, Wis. Adm. Code, shall be complied with and the appropriate data
submitted with the preliminary plat.
E.
Covenants. The Council may require submission of a
list of existing covenants and a list of covenants with which the
subdivider intends to regulate land use in the proposed subdivision
and otherwise protect the proposed development.

plat shall certify on the face of the plat that it is a correct representation
of all existing land divisions and features and that he has fully
complied with the provisions of this chapter.
A.
General requirements. A final plat prepared by a registered
land surveyor shall be required for all subdivisions. It shall comply
in all respects with the requirements of § 236.20, Wis.
Stats.
B.
Additional information. The plat shall show correctly
on its face, in addition to the information required by § 236.20,
Wis. Stats., the following:
(1)
Exact length and bearing of the center line and center
line curves of all streets.
(2)
Exact street width along the right-of-way line of
any obliquely intersecting street.
(3)
Railroad rights-of-way within and abutting the plat.
(4)
Setbacks or building lines, if required by the Plan Commission, in accordance with the guidelines set forth in Article IV of this chapter.
(5)
Utility and/or drainage easements.
(6)
All lands reserved for future public acquisition or
reserved for the common use of property owners within the plat.
(7)
Special restrictions required by the Council relating
to access control along public ways, delineation of floodland limits,
or to the provision of planting strips.
C.
Deed restrictions. The Council may require that deed
restrictions imposed by the subdivider be filed with the final plat.
D.
Plat restrictions. The Council may require that plat
restrictions intended to reflect City plans and ordinances be placed
on the face of the plat.
E.
Survey accuracy. The Director of Public Works shall
examine all final plats within the City and may make, or cause to
be made by a registered land surveyor under the supervision or direction
of the Director of Public Works, 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:
(1)
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 5,000
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.
(2)
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 3,000, 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 1 1/2 minutes 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.
F.
Relocated quarter corners. Where the plat is located
within a quarter section, the corners of which have been relocated,
monumented and coordinated by the county, the tie required by § 236.20(3)(b),
Wis. Stats., shall be expressed in terms of grid bearing and distance,
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. 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.
G.
Council review. The Council shall receive the results
of the Director of Public Works and the state's examination prior
to approving the final plat.
H.
Surveying and monumenting. All final plats shall meet
all the surveying and monumenting requirements of § 236.15,
Wis. Stats.
I.
State Plane Coordinate System. All plats shall be tied directly to a section or quarter corner monumented according to the State Plane Coordinate System. 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 section or quarter corner to which the plat is tied shall be indicated on the plat. The grid bearing and distance of the tie shall be determined by a closed survey meeting the error of closure specified in Subsection E above for the survey of the exterior boundaries of the subdivision. All distances and bearings shall be referenced to the Wisconsin Coordinate System.
J.
Certificates. All final plats shall provide all the
certificates required by § 236.21, Wis. Stats., and, in
addition, the surveyor shall certify that he has fully complied with
all the provisions of this chapter. The subdivider's certificate shall
be fully executed prior to Council approval.
K.
Recordation. The final plat shall be recorded with
the County Register of Deeds by the subdivider only after the certificates
of the Director of the Planning Function in the Wisconsin Department
of Administration, of the Council, and of the surveyor and those certificates
required by § 236.21, Wis. Stats., are placed on the face
of the plat. The Clerk-Treasurer shall sign the plat within 10 days
of its approval by the Council.
[Amended 3-15-2007 by Ord. No. 2007-05]
L.
Duplicate plat to be filed. An identical reproducible
copy, on stable drafting film at least four mils thick, along with
the recording data, shall be placed on file with the Director of Public
Works.
A.
General requirements. A certified survey map prepared by a registered land surveyor shall be required for all minor land divisions. It shall comply in all respects with the requirements of § 236.34, Wis. Stats. The minor subdivision shall comply with the design standards and improvement requirements set forth in Articles IV and V of this chapter.
B.
Required information. The map shall show correctly
on its face, in addition to the information required by § 236.34,
Wis. Stats., the following:
(1)
All existing buildings, watercourses, drainage ditches
and other features pertinent to proper land division.
(2)
Setbacks or building lines, if required by the Plan Commission in accordance with the guidelines set forth in Article IV of this chapter.

(8)
Name and address of the owner, subdivider and surveyor.
C.
State Plane Coordinate System. All plats shall be tied directly to a section or quarter corner monumented according to the State Plane Coordinate System. 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 section or quarter corner to which the plat is tied shall be indicated on the plat. The grid bearing and distance of the tie shall be determined by a closed survey meeting the error of closure specified in § 380-22E of this chapter for the survey of the exterior boundaries of the subdivision. All distances and bearings shall be referenced to the Wisconsin Coordinate System.
D.
Certificates. The surveyor shall certify on the face
of the map that he has fully complied with all the provisions of this
chapter. After reviewing the map, the Council, upon the recommendation
of the Plan Commission, shall certify its approval on the face of
the map. After receiving approval by the Council, such maps shall
be certified by the Mayor, the Clerk-Treasurer and the Director of
Public Works. In addition, dedication of streets and other public
areas shall require the owner's certificate and the mortgagee's certificate
in substantially the same form as required by § 236.21(2)(a),
Wis. Stats.
E.
Approval. No certified survey map shall be approved
by the Council until all required improvements have been installed
and until all required fees have been paid unless provision for the
installation of improvements and payment of fees has been made in
an approved subdivider's agreement.
F.
Recordation. The certified survey map shall only be
recorded with the County Register of Deeds after the certificates
of the Council and the surveyor are placed on the face of the map.
The party submitting the map for approval shall be responsible for
recording the map. The certified survey map is to be recorded within
30 days after being signed by the Clerk-Treasurer.
