shall be kept free of debris at all times for proper drainage.
RIGHT-OF-WAY CLEANUP: Any surplus material resulting from excavation and backfill operations shall be removed from the right of way. All

and drainage ditches shall be replaced to their original standard or better. All excess material shall be removed prior to paving. Water tanker
shall be used, as required, to sprinkle the job site to keep down dust conditions and shall be used immediately after backfill.
DE -WATER OPERTATIONS: If de -watering operations are required and pumps are forcing water on City of La Quinta roads, it shall be the
responsibility of the permittee (contractor) to control this water and to provide off-street barricades when necessary.
CLOSING STREETS: No street shall be closed. A minimum of one lane of traffic shall be maintained at all times to provide limited access for

backfill is placed to ensure the effectiveness of the compaction methods and to establish the depth
of lift that can be compacted.
D. If lifts greater than one foot are attempted in this trial length of trench, compaction tests shall be
taken within the lifts to ensure that the full depth of the lift is compacted. Upon satisfactory
completion of this portion of trench, the City Inspector shall establish the maximum lift thickness
to be compacted for the remainder of the project.
E. In subsequent lengths of trench, the frequency of compaction tests shall equal one per each lift of
backfill, per 300 linear feet of open trench, at randomly selected locations within the open length
of trench.
F. The depth of the randomly selected compaction tests shall also be randomly selected except that
where multiple tests are required in a given length of trench, the tests shall be no closer than three
feet (vertically) from each other.
G. If any compaction test fails, previously placed backfill (in the same length of open trench or
previous lengths of trench) which is represented by the failing test (as determined by the City
Inspector), shall be tested for compliance with compaction requirements.
H. All costs incurred due to the conditions above shall be borne by the Permittee. Copies of all test
results shall be furnished to the City Inspector.
28. All excavations within City of La Quinta right-of-way shall be backfilled, and temporarily paved if
within the existing travel way, at the end of every workday as directed by and to the satisfaction of the
City Engineer for the protection of the public. Lengths of open trench shall not greatly exceed that
which cannot, be backfilled in the same day. Excavated trenches shall not be allowed open overnight,
however, Permittee may leave a length of excavated trench, not to exceed twenty (20) feet in length,
open overnight at a point where construction will begin the next day, provided that this length of trench
is completely covered by steel plating.
29. All landscaping, irrigation, decorative rock, decorative concrete, lighting, etc., shall be replaced to its
original condition.
30. Access and egress to all local properties shall be maintained at all times.
31. Pursuant to Section 14.16.375 of the La Quinta Municipal Code (Ordinance 10 § 1 (part), 1982),
permanent pavement replacement shall be completed no later than seven (7) days after the completion
of the work. Permanent pavement replacement shall conform to the following conditions:
A. Existing asphalt concrete pavement shall be sawcut one (1) foot beyond trench edges. Edges shall
be straight and clean.

B. Permanent pavement replacement structural section, within all trenches, shall be 1" thicker than
existing of asphalt concrete over the same existing thickness of crushed aggregate base or crushed
miscellaneous base, meeting the requirements of Sections 200-2.2 and 200-2.4.of the Standard
Specifications for Public Works Construction. The replaced pavement and base material shall be
compacted to 95% relative compaction and respectively tested, for each 300 linear feet of trench.
Verify exact structural replacement section thicknesses with the City prior to installation.
C. Permanent pavement replacement shall be installed using a City approved 3/" max medium
asphalt concrete as the base course lift and a City approved''/z" max medium finish course lift for
capping. Asphalt concrete mix design shall be approved by the City prior to its placement.
D. Cold -Mill and Overlay - The existing pavement which was properly protected in place during the
trenching operation located adjacent to the trench saw cut shall be cold -milled to a depth of 0.10
feet with butt joint created next to the existing unmilled pavement surface. The cold -milled. area
and base asphalt concrete in the trench area shall be overlaid with a City approved C2-AR-4000
asphalt concrete mix. The width of the cold milling area shall be as follows:
For longitudinal trenches located in a parking lane: three (3) feet outside the sawcut
removal lines.
For longitudinal trenches located in a traffic lane: three (3) feet outside the sawcut removal
lines, or to the lane line striping, whichever is greater.
For transverse trenches across existing street: two (2) feet outside the sawcut removal lines.
E. If grinding and capping operations are not performed in the same day as base paving operations,
the base course lift of /" max medium asphalt concrete shall be installed from saw -cut edge to
saw -cut edge flush.with the existing street surface. The base course lift of paving shall not be left
0.10' low in anticipation of grinding and capping.
F. Any existing lane striping or any existing detour lane.striping affected by this resurfacing shall be
replaced in kind by the Permittee, as directed by and to the satisfaction of the City Engineer.
Affected traffic signal loops shall be removed and replaced in kind. The finished pavement
surface shall be smooth, consistent, and shall conform to the surrounding grades.
