[CC 1992 §510.140; Ord. No. 397 §2, 7-9-1985]
A. Water
and gas lines running across City streets, sidewalks and other public
places, shall be pushed or bored by a tunneling method unless it is
shown that tunneling cannot be accomplished. In that event the Director
of Public Works shall be notified and permission must be given prior
to utilizing an alternative method such as a trench excavation. No
excavation may be opened larger than three (3) feet by four (4) feet,
provided that larger openings may be made when approved by the Director
of Public Works or his/her designated representative.
B. No cut
shall be made without the approval of the inspection office and the
inspection office shall be informed when backfilling operations are
ready.
[CC 1992 §510.150; Ord. No. 397 §3, 7-9-1985]
A. AB-3
rock (concrete rock with dust) is to be used for backfill up to the
lower surface of the existing and surface materials. The AB-3 rock
shall be placed in successive lifts of not more than twelve (12) inches
and each lift is to be compacted by mechanical means. The AB-3 rock
is to contain moisture sufficient to result in a finished base equal
to or greater than the density of the adjacent material.
B. All service
cut trenches with a width of twenty-four (24) inches or more shall
cut the surface and subsurface back twelve (12) inches around the
excavation.
C. On all
curbed and guttered streets, regardless of existing surface, the street
cut shall be filled with 3,000 p.s.i. concrete to a minimum of six
(6) inches or from the base of the original pavement whichever is
the greater. The concrete shall be flat-finished and neatly edged.
Seal coat surfacings shall be replaced with a minimum of four (4)
inches of asphalt. Hot mix asphalt shall be used. If seasonal or availability
conditions warrant, cold mix asphalt may be used provided the cold
mix equals the hot mix density. Rock or gravel roads and alleys are
to be backfilled with AB-3 compacted to a density equal to or greater
than the adjacent undisturbed area, then covered with rock that equals
the original surface in size.
D. Asphalt
and concrete are to be saw cuts and shall be parallel to the trench
with corner angles being not less than ninety degrees (90°). The
saw cut may be made when the cut is filled and is not required to
be done at the time the cut is opened.
E. All finished
surfaces are to be checked with a straight edge or string line at
the time of finishing or tamping of the asphalt.
F. Excavations
under sidewalks are to be backfilled with AB-3 and thoroughly tamped
to achieve a density to prevent settlement.
G. Excavations
extending back of the curb line or beyond the ditch line of gravel
or seal coated streets shall be backfilled with the material from
the excavation and further the initial four (4) feet shall be backfilled
in six (6) inch lifts and tamped to ninety-five percent (95%) of optimum
density using the standard proctor test as performed by a commercial
test laboratory. Wet material that will not meet optimum moisture
density shall be modified by the addition of four percent (4%) of
hydrated or quick lime by volume. Existing ground cover is to be replaced
by either stockpiled sod or freshly cut sod or seeding and fertilizer
as may be approved by the Director of Public Works or his/her designated
representative when the backfill is completed. Sodding or seeding
is expected to be completed during the same day or the next working
day. Backfill with frozen dirt may be done with the explicit understanding
that the trench fill material is to be re-excavated and tamped when
the ground thaws. In the event the inspector declares an excavation
appears not to meet this standard the contractor may elect the following:
1. To have
a minimum (2) shelby tube samples taken in the finished excavation
to determine the in place density to be compared to an adjacent undisturbed
sample. If the compacted materials fail to equal or exceed the level
of adjacent soil density values, in the opinion of the commercial
test laboratory, then the contractor will remove and replace all the
trench fill materials. The Building Inspector or designated representative
shall be sole judge of the quality of fill.
2. Replace
the fill in its entirety to the heretofore enumerated standards.
[CC 1992 §510.160; Ord. No. 397 §4, 7-9-1985]
During a period of one (1) year from and after the date that
any backfilling operation is completed, the contractor shall make
all needed repairs arising out of defective workmanship or materials
or both, which, in the judgment of the City, shall become necessary
during such period.
[CC 1992 §510.170; Ord. No. 397 §5, 7-9-1985]
Any person being authorized under the ordinance of the City
to make any excavation or opening in any of the streets, alleys or
public grounds of the City is required to obtain a permit therefore
and must notify City Hall before starting an excavation.
[CC 1992 §510.180; Ord. No. 397 §6, 7-9-1985]
Before excavation commences, the one holding the permit shall
first make and file with the City Clerk a performance and maintenance
bond in a sum equal to the contract amount of the work with good and
sufficient sureties to be approved by the City. All work to be done
shall be guaranteed and kept in repair by the contractor for a period
of one (1) year from the date of its acceptance by the inspector.
This guaranty includes all maintenance and repairs necessary to keep
the work in first class condition. If, in the judgment of the inspector,
repairs or renewals become necessary, then, upon notice at any time
during the guarantee period by the inspector to the contractor, said
repairs or renewals shall be promptly made and at the expense of the
contractor who shall take out and remove all soft, inferior or defective
materials found in any of the work done by him/her and replace same
with good and acceptable materials and to do all work necessary to
put such pavement in first class condition and said person further
agrees and binds himself/herself that said improvements for such terms
shall be and remain in good, serviceable condition, smooth and free
from any defects that will impair its usefulness as a roadway; that
upon failure of the person to undertake said repair or replacement
within the time period contained in the notice to the person from
the inspector the Director of Public Works may undertake said repair
or replacement and make claim against the bond for the actual cost
incurred including administrative charges, if any, incurred by the
City.
[CC 1992 §510.190; Ord. No. 397 §7, 7-9-1985]
Every person before making any excavation within the public right-of-way shall cause a certificate of insurance to be posted with the City Clerk, in compliance with Section
515.030 hereof, said certificate shall also provide that the policy of insurance shall not be canceled, amended, changed or altered without giving the City Clerk ten (10) days' written notice thereof. Such certificate shall further provide for the indemnification of any person who shall incur damage claimed as a result of any of the work performed shall hold the City harmless and indemnify the City for any claim for damages as a result of said excavation or work related thereto by said contractor.
[CC 1992 §510.200; Ord. No. 397 §8, 7-9-1985]
Any person being authorized under the ordinance of the City
to make any excavation or opening in any of the streets, alleys or
public grounds of the City, shall notify the inspector designating
the location, number of openings, the purpose for which the same is
to be made, and the time within which the undertaking is to be completed.
