It shall be the duty of the abutting owner to build, repair,
construct and perpetually maintain sidewalks along or upon any street,
alley or highway in the Village and to pay the entire cost thereof.
Whenever the Village Board by resolution determines that a sidewalk
shall be laid, rebuilt, repaired, lowered or raised along or upon
any public street, alley, or highway within the Village, it shall
proceed according to § 66.0907, Wis. Stats.
No person shall hereafter lay, remove, replace or repair any
public sidewalk within the Village unless he is under contract with
the Village to do such work or has obtained a permit therefor from
the Village Board, or its authorized representative, at least seven
days before work is proposed to be undertaken. No fee shall be charged
for such permit.
All sidewalks within the Village hereafter shall be repaired,
rebuilt, and constructed in accordance with the following specifications:
A.
Subgrade. The subgrade shall be prepared by excavating to the line,
grade and cross section as established by the Village Board. Soft
and unsuitable material shall be removed and replaced with sand or
other satisfactory material, and the subgrade shall be thoroughly
and uniformly compacted and moistened immediately before the concrete
is placed. When so specified by the Village Board or its authorized
representative, a sub-base of sand, sand and gravel, or other approved
porous material shall be placed under the sidewalk. On embankments,
the subgrade shall extend at least one foot beyond each edge of the
sidewalk.
B.
Material. All sidewalks shall be of air-entrained concrete composed
of six bags per cubic yard of one-course construction and built to
the established line and grade. Gravel shall be of good quality and
washed. Concrete shall be mixed thoroughly for a minimum of one minute
after all materials have been placed in the mixer.
C.
Forms. Concrete shall be placed in straight forms of wood or metal
of sufficient strength to resist springing, tipping or other displacement
during the process of depositing and consolidating the concrete. Wood
forms shall be surfaced plank of at least two-inch thickness, except
for sharply curved sections. Metal forms shall be of approved sections.
The forms shall be of full depth of the required walk and shall be
of such design as to permit secure fastening. Forms shall be thoroughly
cleaned and oiled before the concrete is placed against them. Concrete
shall be placed in the forms on a moist subgrade, deposited just above
the finished grade and consolidated and spaded sufficiently to bring
the mortar to the surface and to prevent honeycombing. It shall then
be struck off level with the top of the forms and finished with wooden
flats. To provide adequate drainage, the sidewalk shall slope toward
the curb at a minimum rate of 1/4 inch per foot of width of sidewalk.
All joints and edges shall be finished with a one-fourth-inch-radius
edging tool.
D.
Width and thickness. Residential walks shall be four feet in width
and not less than four inches thick, provided that walks in residential
areas may be repaired or replaced to a width not less than the existing
width on the effective date of this article. Sidewalks in front of
commercial or industrial establishments shall be not less than eight
feet in width and five inches in thickness.
E.
Finishing. Before the last finish has set, the sidewalk shall be
steel troweled and brushed in transverse direction. Before final finishing,
the surface shall be checked with a ten-foot straight edge, and any
areas departing more than 1/8 inch from the testing edge shall be
corrected by adding or removing concrete while the concrete in the
walk is still plastic.
F.
Jointing. Transverse, full depth, one-half-inch-thick expansion joints
of premolded expansion material shall be located every 30 feet and
at the property line, and where the walk intersects another walk,
curbline, building or driveway approach, and at buildings, walls,
poles and stop boxes. The expansion joint material shall be placed
in a neat and workmanlike manner with its upper edge slightly above
the finished sidewalk surface. Dummy grove joints for controlled cracking,
at least one inch in thickness and 5/16 inch in depth, shall be placed
at intervals of approximately five feet. Steel division plates shall
be placed at right angles to the center line of the sidewalk at intervals
of not less than 15 feet. All joints shall be at right angles to the
direction and grade of the walk. Diagonal joints may be used only
when approved by the Village Board or its authorized representative.
G.
Curing and drying. As soon as any of the concrete work mentioned
in this section has been finished and hardened sufficiently to prevent
excessive marring of the surface, it shall be cured and protected
against rapid drying. Failure to comply with this requirement shall
be deemed sufficient cause for suspension of the work. Curing shall
be accomplished by the impervious coating, wet fabric or paper methods.
For impervious coating or membrane curing, only those materials meeting
requirements of ASTM Specification C156-44T, Method of Test for Efficiency
of Materials for Curing Concrete, shall be used. The specifications
are adopted by reference as if fully set forth in this section. Walks
shall be kept free from all traffic at normal temperatures for 48
hours and in cold weather (below 50° F.) for 96 hours. No concrete
shall be poured when the temperature may be expected to fall below
35° F. in any seventy-two-hour period or upon frozen subgrade.
