The Village substreet utility excavation and trench backfill
policy is established. The policy shall become effective as of May
1, 2018, and shall consist of the following provisions.
A.
Beginning on May 1, 2018, and thereafter, all street cut trenches
made either to existing pavements or sidewalks or future pavement
areas shall be backfilled utilizing one of two recommended methods:
those being the use of controlled low strength materials (CLSM) or,
alternately, the placement of thin (six-inch maximum thickness) mechanically
compacted lifts of IDOT-approved coarse aggregate CA-6 or CA-10 materials
as approved by the Village Superintendent of Public Works. Coarse
aggregate materials shall be compacted to 95% of their optimum density,
Standard Proctor. Water inundation or jetting of the fine aggregate
backfill material is not permitted. The proper backfill shall extend
not less than two feet in each direction from the edge of the pavement.
B.
"CLSM" is defined as a mixture of Portland cement, fine aggregate,
water, fly ash and air-entraining admixtures. The mix shall be proportioned
to provide a backfill material which is self-compacting and capable
of being excavated with hand tools, as necessary, at a later date.
Materials and proportioning shall comply with IDOT's Special
Provision for Controlled Low-Strength Material as adopted on January
1, 1990, and revised as of March 1, 1990, or shall consist of one
of the mix designs as shown below:
|
MIX NO. 1
| |
|---|---|
|
Portland cement
|
50 lbs.
|
|
Fly ash
|
200 lbs.
|
|
Fine aggregate (SSD saturated surface dry)
|
2,990 lbs.
|
|
Water
|
49 — 57 gallons (as directed)
|
|
MIX NO. 2
| |
|---|---|
|
Portland cement
|
185 lbs.
|
|
Fine aggregate (SSD saturated surface dry)
|
2,990 lbs.
|
|
Air-entraining admixtures
|
6 fluid ounces
|
|
Water
|
49 — 57 gal. (as directed)
|
C.
For both the CLSM and granular backfill methods, the top 12 inches
of the excavation shall be filled with soil of similar composition
to that of the adjacent subgrade. The 12 inches of soil shall be compacted
to at least 95% of maximum dry density. (AASHTO T99) with no more
than 110% optimum moisture.
Placement of CLSM, operation limitations, measurement methods
and basis of payment, if applicable, shall all be in compliance with
the IDOT Special Provision For Controlled Low-Strength Material as
adopted January 1, 1990, and revised thereafter.
When a trench is cut into an existing concrete street or sidewalk,
the pavement shall be replaced in kind with a total thickness two
inches greater than existing, to a maximum of 10 inches. When restoring
concrete pavement, the entire slab into which the trench was cut shall
be removed and replaced. If the surface is either asphalt or oil and
chip, a six-inch concrete replacement layer shall be installed and
two inches of bituminous concrete base shall be placed over the base.
Replacement pavement shall be installed no less than a distance of
two feet in each direction from the edge of the excavation trench.
A.
All utility structures (e.g., shut-off valves, vault boxes, lids,
poles, lines, markers, etc.) that pose a threat to public safety shall
be replaced when directed by the Village Superintendent of Public
Works. Failure to make the repairs within an approved time frame will
result in a penalty of $75 per day.
B.
Any failures occurring outside of the original restored or repaired
pavement or right-of-way area resulting from the utility activity
will be repaired by the responsible utility company.
Any person, firm, corporation or entity which plans to install
any underground utilities within a present or proposed street or sidewalk
right-of-way area is required to notify the Village Superintendent
of Public Works a minimum of 24 hours prior to beginning work. The
notification shall include the exact location and nature of the work
to be performed. In emergency situations, the Village shall be notified
immediately upon the responsible party's decision that excavation
is required. Roadway or sidewalk area repairs or restorations made
without proper notification may require re-excavation and replacement
with approved backfill.
A.
Variance from any of the utility excavation policy provisions as
stated above may be granted, on a case-by-case evaluation basis, by
the Village Superintendent of Public Works. All variances granted
shall be specifically outlined in writing and include a justification
for the variance. Factors to be considered in rendering a variance
decision may include, but not be limited to:
B.
Any questions, concerns or disputes regarding interpretation or administration
of this article may be referred by an affected party to a Village
Board who, by majority vote, shall have final authority in resolving
such matters.
A.
Permits are required for utility excavations within any Village right-of-way.
B.
Such utility work within or affecting the Village rights-of-way will
require the contractor to furnish the Village Engineer evidence of
liability insurance coverage naming the "Village of Oakwood, Illinois"
as an additional insured. Additionally, a three-year bond for an amount
equal to $10,000 or 115% of the estimated value of the repair, whichever
is greater, will be required for any such utility work that requires
street cuts or sidewalk cuts or other removal and replacement of Village
infrastructure.
C.
The Village Superintendent of Public Works is empowered to issue
right-of-way excavation permits for any use of Village streets or
other public property for periods of no longer than 180 days for construction
purposes.
D.
Subject to any applicable franchise agreement provisions, fees for
issuance of a temporary permit pursuant to this section shall be as
follows:

will cover up to one mile in length. Additional permits will be required
for each additional mile.
F.
The Village of Oakwood reserves the right to require appropriate
traffic control measures as shown in the Illinois Department of Transportation's
Highway Standards in areas affected by the utility work as directed
by the Village Engineer or Superintendent of Public Works.
