A final plat prepared by a professional 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 of all streets;
B. Exact street width along the line of any obliquely intersecting street;
C. Railroad rights-of-way within and abutting the plat;
D. Setbacks or building lines;
E. Utility and/or drainage easements;
F. Street addresses on each lot as determined by the Village Clerk;
G. All lands reserved for future public acquisition or reserved for
the common use of property owners within the plat;
H. Special restrictions required by the Village Plan Commission relating
to access control along public ways or to the provision of planting
strips.
The Village Plan Commission may require that deed restrictions
be filed with the final plat and shall be recorded with the approved
plat.
The Village Engineer shall examine all final plats within the
Village and may make, or cause to be made by a professional land surveyor
under the supervision or direction of the Village 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 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. 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. Where the plat is located within a U.S. Public Land Survey quarter-section
the corners of which have been relocated, monumented and coordinated
by the Village of Williams Bay, Walworth County or the Southeastern
Wisconsin Regional Planning Commission, 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.
D. The Village Board shall receive the results of the Village Engineer's
examination prior to approving the final plat.
All final plats shall meet all the surveying and monumenting
requirements of § 236.15, Wis. Stats.
Where the plat is located within a U.S. Public Land Survey quarter
section the corners of which have been relocated, monumented and coordinated
by the Village of Williams Bay, Walworth County or the Southeastern
Wisconsin Regional Planning Commission, the plat shall be tied directly
to one of the section or quarter corners so relocated, monumented
and coordinated. 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. All distances and bearings shall be referenced to the Wisconsin
Coordinate System, South Zone, and adjusted to the Village's control
survey.
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.
