survey monuments placed in accordance with the requirements of Section
236.15 of the Wisconsin Statutes and as may be required by the Village
Board.
After the installation of temporary block corner
monuments by the subdivider or land divider and establishment of street
grades by the Village Board, the subdivider or land divider shall
grade the full width of the right-of-way of all streets proposed to
be dedicated in accordance with plans and standard specifications
approved by the Village Engineer. The subdivider or land divider shall
grade the roadbeds in the street rights-of-way to subgrade.
After the installation of all utility and stormwater
drainage improvements, the subdivider or land divider shall surface
all roadways in streets proposed to be dedicated to the widths prescribed
by these regulations. Said surfacing shall be done in accordance with
plans and standard specifications approved by the Village Board and
the Dane County Highway Department where County approval is required.
A. Establishment of lines and grades. All improvements
shall be built in accordance with the lines and grades shown on the
plans or as given by the Engineer. The contractor shall provide such
materials (stakes, etc.) and give such assistance, including a qualified
helper, as may be required for setting lines and grades. Stakes or
marks so given shall be carefully preserved. The contractor shall
keep the Engineer informed a reasonable time in advance, at least
24 hours, as to his need for additional grade stakes.
B. Equipment. The contractor shall provide equipment
that is adequate and suitable for completing the work in accordance
with the specifications for the project.
C. Preparation of subgrade.
(1) All debris, vegetation or other perishable materials
shall be removed from the site. The area to be paved shall be excavated
or filled as required. No material shall be placed on frozen ground.
Material in soft spots shall be removed to a depth required to provide
a firm foundation and shall be replaced with material approved by
the Village Engineer. The Village Board may also require an underdrain
system to drain the subgrade. All excess material shall be disposed
of at the direction of the subdivider or land divider.
(2) The entire subgrade, and especially utility trenches,
shall be compacted to the degree that no further appreciable consolidation
is evidenced under the action of the compaction equipment. The surface
of the subgrade after compaction shall be hard, uniform, smooth and
true to grade and cross section. The subgrade shall be accepted by
the Village Engineer contingent on satisfactory compaction as evidenced
by compaction test results made during utility construction, the tests
to be paid for by the subdivider or land divider.
D. Thickness of structure.
(1) The thickness of the pavement will vary depending
on the classification of the street and the thickness specified on
the plans. The following table lists the various minimum required
thicknesses.
(2) The Village Board may require that the thickness of
the pavement on arterial or collector streets be designed in accordance
with the Wisconsin Department of Transportation Facilities Development
Manual using design parameters obtained from soil borings.

(1) Unless otherwise provided in the contract, aggregates
for the top layer of base course shall be Gradation No. 2 and aggregates
for the lower layer shall be Gradation No. 1 or No. 2.
(2) No base material shall be placed on a subgrade that
is soft or spongy or one that is covered by ice or snow. No base material
shall be placed on a dry or dusty subgrade where the existing condition
would cause rapid dissipation of moisture from the base material or
preclude its proper compaction. Such dry subgrades shall have water
applied to them and shall be reworked and recompacted if necessary.
(3) The contractor shall maintain the prepared subgrade
ahead of the base laying operation in a smooth condition. Any ruts
or surface irregularities produced by hauling equipment or traffic
shall be removed.
(4) The crushed aggregate base course shall be placed
in two or more layers. The material shall be spread in uniform, uncompacted
lifts not to exceed six inches each. Unless otherwise provided for
in the contract, each layer shall be compacted to the degree that
there will be no appreciable displacement of it laterally or longitudinally
under the compaction equipment.
F. Aggregate for bituminous concrete pavement.
(1) The aggregate for asphalt plant mix shall consist
of course aggregate, fine aggregate and, if needed, mineral filler.
The fine aggregate shall be well graded, moderately sharp to sharp
sands. If mineral filler is required, it shall meet Section 401.2.6

Gradation taken from Section 401.2.5 of the
State of Wisconsin Department of Transportation Standard Specifications
for Road and Bridge Construction.
|
(2) Unless otherwise provided for in the contract, the
aggregate for the binder course shall conform to Gradation No. 1 or
2 and the aggregate for the surface course shall conform to Gradation
No. 2. The exact amount of bitumen shall be determined by sample mixes
which must show grains completely coated. Samples shall not bleed
when compacted. The amount of bitumen shall be approved by the Village
Engineer.
G. Asphalt. The asphalt for the plant mix bituminous
binder and surface courses shall be AC with a penetration of 85-100
for arterials and 120-150 for collectors and minor streets and shall
conform to the requirements of ASSHTO Designation T49 or ASTM Spec.
D-946-63T.
H. Spreading and finishing bituminous mixtures.
(1) The binder and surface courses shall not be placed
when the air temperature is less than 45° F. The binder course
shall be placed in one course and the surface course shall be placed
in one course by means of a self-propelled spreading and finishing
machine with a vibratory screed. The binder course shall be spread
at a temperature between 225° F and 300° F and the surface
course at a temperature between 250° F and 300° F.
(2) The binder course shall be kept clean until covered
with the surface course. Longitudinal joints in the surface course
shall not be placed immediately over joints in the binder course.
Joints between old and new pavements or between successive days' work
shall be made so as to ensure thorough and continuous bond between
the pavements.
I. Compaction of bituminous mixtures.
(1) After each course is spread and while it is still
hot, it shall be compacted thoroughly and uniformly by rolling. Compaction
shall conform to the State of Wisconsin Department of Transportation
Standard Specifications for Road and Bridge Construction, Section
405.5.
(2) Rolling should begin at the sides and proceed parallel
to the road center line, each trip overlapping 1/2 the roller width,
progressing to the crown of the road. Rolling shall continue until
all roller marks are eliminated and no further compaction is possible.
In places adjacent to curbs, manholes and similar structures not accessible
to the roller, the mixture shall be thoroughly compacted with hot
hand tampers or with mechanical tampers giving equivalent compaction.
J. Smoothness. The surface of the courses shall be tested
at selected locations using a ten-foot straight edge placed parallel
to the center line of the pavement.
(1) Surface courses shall show no variation greater than
1/8 inch from the testing edge of the straight edge between any two
contacts with the surface. Binder courses shall show no variation
greater than 1/4 inch from the testing edge of the straight edge between
any two contacts with the surface. The surface course shall be a minimum
1/8 inch higher than the curb flag.
(2) Variations exceeding 1/4 inch in the binder course
shall be corrected as directed by the Engineer. For each variation
in the surface course greater than 1/8 inch but less that 1/4 inch
there shall be deducted from the amount due to the contractor and
paid to the Village 1/6 the contract price per ton of surface course
mixture for each ton of surface course mixture placed. If variations
in the surface course exceed 1/4 inch, the entire area affected shall
be removed and replaced with fresh surface mixture before acceptance.
K. Sampling and testing. If requested by the Village
Engineer, the contractor shall furnish for test and analysis representative
samples of the materials to be used in the work. Sampling and testing
shall be in accordance with the latest revisions of ASSHTO or ASTM
standard procedures for sampling and testing.
L. Protection of work. The contractor shall provide and
maintain proper barricades, fences, signal lights or watchmen to protect
the work from traffic and to protect persons, animals and property
from injury or damage.
The subdivider or land divider shall construct
a concrete sidewalk on both sides of all collector streets within
the subdivisions and land divisions. The Village Board may require
the construction of sidewalks on minor streets that serve subdivisions
and land divisions with a gross density of four dwelling units per
acre or more.
A. Sidewalk design standard. Standard sidewalks in the
Village shall have a width of four feet and a concrete thickness of
four inches. Wherever possible, a minimum provision for sidewalk concrete
thickness of six inches for driveway crossover shall be made. Sidewalk
construction methods shall conform to the State of Wisconsin Department
of Transportation Standard Specifications for Road and Bridge Construction
Section 602.3 (1981 Edition).
B. Wider than standard sidewalks may be required by the
Village Board in the vicinity of schools, commercial areas and other
places of public assemblage, and the Village Board may require the
construction of sidewalks in locations other than required under the
preceding provisions of this chapter if such walks are necessary,
in its opinion, for safe and adequate pedestrian circulation.
C. Alternate pedestrianways may be approved in lieu of
sidewalks where the proposed alternative pedestrianways are constructed
of all-weather material, are dedicated to the Village or are owned
and maintained by a properly registered homeowners' association and
have frontage on each parcel otherwise required to be provided with
a sidewalk.
The subdivider or land divider shall construct
water mains and laterals in such a manner as to make adequate water
service available at the street right-of-way line of each lot within
the subdivision or land division. If municipal water service is not
available, the subdivider or land divider shall make provision for
adequate private water systems as specified by the Village and Wisconsin
State and County Boards of Health. The size, type and installation
of all public water mains proposed to be constructed shall be in accordance
with plans and specifications approved by the Village Board.
A. Wherever possible, water mains shall be located on
the north or west side of streets. Fire hydrants shall be located
no greater than 450 feet apart in residential areas and no greater
than 300 feet apart in commercial or industrial areas.
B. Within the Village, the subdivider or land divider
shall assume the cost of installing all water mains and laterals required
to facilitate the contemplated flows within the subdivision or land
division. The Village may require the subdivider or land divider to
increase the size of the water main to service an area outside of
the subdivision or land division. The increased cost of this larger
water main over and above that of the water main needed for the subdivision
or land division shall be borne by the Village or assessed against
the tributary area if it is larger than eight inches in diameter.
The subdivider or land divider shall install
street lamps along all streets proposed to be dedicated of a design
compatible with the neighborhood and type of development proposed.
Such lamps shall be placed at each street intersection and at such
interior block spacing as may be required by the Village Board. Plans
and specifications shall be approved by the Village Board.
[Amended 6-21-2021 by Ord. No. 05-2021]
The subdivider or land divider shall plant at least one tree
of a species acceptable to the Village Board and of at least six feet
in height for each 50 feet of frontage on all streets proposed to
be dedicated. The installation of street trees shall consider solar
access objectives in the selection of tree species and planting location
so as to minimize future shading of the most southerly side of contemplated
building locations. The required trees shall be planted in accordance
with plans and specifications approved by the Village Board.
The subdivider or land divider shall install
street name signs at all street intersections. Plans and specifications
shall be approved by the Village Board.
