A.
Every opening and excavation shall be enclosed with sufficient barriers,
signing, and such other traffic control devices as may be required
by the Village and in accordance with Section VI of the Manual on
Uniform Traffic Control Devices. Sufficient warning lights shall be
kept on from sunrise to sunset. No open flame warning devices shall
be used. Except by special permission from the Superintendent of Public
Works, no trench shall be excavated more than 250 feet in advance
of pipe or conduit laying nor left unfilled more than 500 feet from
where pipe or conduit has been laid.
B.
All necessary precautions shall be taken to guard the public effectively
from accidents or damage to persons or property through the period
of the work. Each person making such opening shall be held liable
for all damages, including costs incurred by the Village in defending
any action brought against it for damages, as well as cost of any
appeal, that may result from the neglect by such person or his employees
of any necessary precaution against injury or damage to persons, vehicles
or property of any kind.
C.
Unless otherwise approved, a minimum of one lane of traffic in each
direction shall be provided. Every effort shall be made on the part
of the permittee to provide reasonable access to all properties adjacent
to his project. In the event traffic is limited to less than one lane
in each direction, a flagman or temporary traffic control signal shall
be provided so as to safely cycle traffic in each direction past the
work area.
D.
The permittee shall perform the work in such a manner so as not to
disrupt the flow of traffic in the area or endanger the safety of
workmen or passersby. It shall be the responsibility of the permittee
to prevent traffic backup during construction operation. The permittee
shall notify the Superintendent of Public Works 24 hours prior to
commencement of excavation of the location and extent of the excavation
unless the excavation is an emergency excavation as identified in
§ 12.08.08D.
E.
When the operations will result in the loss of any utility service
to private properties, the private properties shall be notified in
writing or by personal contact at least 12 hours prior to the loss
of service, unless the operations are part of an emergency excavation
as defined in § 12.08.08D.

A.
Removal of existing pavement shall be to neat, straight lines. The
permittee shall make a final saw cut in the existing pavement after
backfilling. Excavations shall be kept to the minimum possible and
acceptable for the convenience and safe performance of his work and
in accordance with all applicable codes and regulations.
B.
If the pavement is damaged during excavation beyond the original
saw cut lines, it shall be saw cut again along neat, straight lines.
The finished saw cut shall leave a regular rectangular section for
pavement replacement. Should the street opening occur within adjacent
or close to an existing patch or require more than one opening within
a short distance, the permittee shall identify and locate the existing
patches or additional openings on the permit application form. The
Superintendent of Public Works or his designee shall, on the basis
of an on-site inspection, approximate the boundaries of the pavement
replacement area.
C.
Pavement replacement areas with the long dimension in the direction
of travel shall have the long dimension parallel with the curbline
or the direction of travel. Pavement replacement areas in concrete
pavements shall be parallel with or at right angles to the direction
of travel. Concrete pavement replacement shall be full panel replacement,
unless determined otherwise by the Superintendent of Public Works
or his designee.
D.
The Superintendent of Public Works or his designee may order the
permittee to remove and replace up to one full lane width of pavement
along the patched or excavated area. Special care shall be taken with
concrete pavement to produce a vertical face on the existing concrete
at the point of the saw cut to insure a full depth of concrete at
the joint.

A.
All excavated material shall be piled in a manner such that pedestrian
and motor traffic is not unnecessarily disrupted. Gutters shall be
kept clear or other satisfactory provisions made for street drainage,
and natural watercourses shall not be obstructed.
C.
Excavated material to be used for backfilling of the trench must
be so handled and placed as to be of as little inconvenience as practical
to public travel and adjoining tenants.
[8-21-2023 by Ord. No.

A.
All backfill material shall be in conformance with the Village of
Darien's Construction Material Standards and Specifications.
B.
In refilling the excavation, if there is not sufficient material
excavated suitable for refilling, the deficiency shall be made up
with material, approved prior to use by the Superintendent of Public
Works or his designee, hauled in.
C.
Wherever an excavation crosses an existing utility, pipe or other
structure, backfill shall be carefully compacted in stages from the
bottom of the excavation. Any sanitary sewer, storm sewer, water,
telephone, natural gas or other service shall not be interrupted by
the permittee. It shall be the permittee's responsibility to
have the various utilities locate and mark their facilities prior
to excavation.
D.
Mechanical compaction shall be used on all granular materials used
for trench backfill. Each layer (twelve-inch maximum) shall be uniformly
compacted to a dry density of at least 95% of the maximum dry density
as determined by the Modified Proctor Test (ASTM-1557). Compaction
or consolidation by flooding shall not be permitted.
E.
All excavations shall be subject to testing by the Village. Backfilled
material not achieving the above compaction requirements shall be
removed and recompacted by the permittee. The cost of any retesting
shall be paid by the permittee.
F.
When the sides of the trench will not stand perpendicular, sheathing
and braces shall be used to prevent caving. No timber, bracing, lagging,
sheathing or other lumber shall be left in any trench. The permittee
is responsible for all safety measures, requirements, codes and adherence
thereto. At no time shall any street pavements be permitted to overhang
the excavation.
[8-21-2023 by Ord. No.

It shall be the duty of the permittee to notify the Superintendent
of Public Works and all public and private individuals, firms and
corporations affected by the work to be done at least one business
day before such work is to commence. The Superintendent of Public
Works shall also be notified at least four hours prior to backfilling
and/or restoring the surface.
[8-21-2023 by Ord. No.

A.
Backfill material shall be left below the original surface to allow
for 12 inches of compacted 3/4 inch crushed stone, plus the thickness
of the required pavement structure. If paving will not occur as part
of the initial street restoration operation, the balance of the opening
to the original surface elevation shall be backfilled with compacted
3/4 inch crushed stone.
B.
Bituminous pavement shall be placed the full depth of the existing
pavement or four inches, whichever is greater. Bituminous pavement
shall be placed in a maximum of 1 3/4 inch layers with each layer
compacted to maximum density and shall consist of materials in conformance
with the Village of Darien's Construction Material Standards
and Specifications for the surface and binder courses. The finished
surface shall be smooth and free of surface irregularities and shall
match the existing pavement and any castings or street appurtenances.
Allowable deviations shall be no more than 1/4 inch as measured with
a ten-foot straight edge.
C.
Concrete pavement shall be placed to the full depth of the existing
pavement or seven inches, whichever is greater. Concrete used shall
not contain calcium chloride. The surface shall be given a light broom
finish. The edges shall be tooled to prevent spalling at the saw-cut
edge. The surface shall be evenly and completely sealed with a white-pigmented
curing compound. The surface shall be protected from traffic for a
minimum of three days. Tie bars shall be installed as directed by
the Superintendent of Public Works or his designee.

In emergency excavations during winter months when it is not
possible to replace the removed pavement with a like material, the
excavation shall be temporarily resurfaced with a minimum of 3 1/2
inches of cold-mix bituminous material. This temporary wearing surface
shall be compacted and rolled smooth. These temporary wearing surfaces
shall be removed and replaced with material as specified above by
not later than the following June 1, except as provided above. Permanent
pavements shall be replaced within 60 days of the date of the permit.
