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.
The plat shall show correctly on its face, in
addition to the information required by § 236.20, Wis. Stats.,
the following:
A.
Exact length and bearing of the center line and center-line
curves of all streets.
B.
Exact street width along the right-of-way line of
any obliquely intersecting street.
C.
Railroad rights-of-way within and abutting the plat.
D.
Setbacks or building lines, if required by the Plan Commission, in accordance with the guidelines set forth in Article VIII of this chapter.
E.
Utility and/or drainage easements.
F.
All lands reserved for future public acquisition or
reserved for the common use of property owners within the plat.
G.
Special restrictions required by the Council relating
to access control along public ways, delineation of floodland limits,
or the provision of planting strips.
The Council may require that deed restrictions
imposed by the subdivider be filed with the final plat.
The Council may require that plat restrictions
intended to reflect City plans and ordinances be placed on the face
of the plat.
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:
A.
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.
B.
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.
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.
The Council shall review the results of the
Director of Public Works and the state's examination prior to approving
the final plat.
All finals plats shall meet all the surveying
and monumenting requirements of § 236.15, Wis. Stats.
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 § 425-33 above for the survey of the exterior boundaries of the subdivision. All distances and bearings shall be referenced to the Wisconsin coordinate system.
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.[1]
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.
