the county shall be used to protect existing carriers which by reason of shallow
bury or location makes them vulnerable to damage from road construction or
maintenance operations.
Existing carriers may remain in place without further protective measures if they
are of adequate depth and do not conflict with road construction or maintenance
and provided that the utility and the county mutually agree that the lines are,
and will remain, structurally sound and operationally safe.
UNDERGROUND UTILITIES. APPURTENANCES
(1)
Vents shall be required for casings, tunnels and galleries enclosing carriers of
fuel where required by federal safety standards. Vent standpipes should be

Drains shall be required for casings, tunnels or galleries enclosing carriers of
liquid, liquified gas or heavy gas. Drains for carriers of hazardous materials shall
be directed to natural or artificial holding areas that will prevent the potential
for surface or ground water contamination. Drains for which only water or other
non-hazardous liquids may discharge may be directed into the roadway ditch or
natural water course at locations approved by the county. The drain outfall shall
not be used as a wasteway for routine purging of the carrier unless specifically
authorized by the county.
Location markers and emergency information should be conspicuously used for
all underground utilities, using color if necessary to contrast with the
environment. They generally should be provided at each end of a roadway
crossing, at each significant change in the utility's alignment, and at SOD-foot
intervals (or within line of sight, whichever is lesser) along a longitudinal
installation. Markers shall include carrier identification and station, owner of
the carrier, and telephone number or other means of contact with a local or
regional office. Markers may also include cover, size, pressure and contents of
carrier, and potential of ducted wires and cables.
Manholes should be designed and located in a manner that will cause the least
interference to other utilities or future road expansion. Where practicable,
installations in the pavement or shoulders should be avoided.
Automatic shutoff valves shall be installed in line at or near ends of structures
and near unusual hazards unless the hazardous segments can be isolated by other
sectionalizing devices within a reasonable distance.
For all installations of fiber optic communication cables, a buried marker tape
identifying the nature of the installation shall be included and placed 18 inches
below the finished ground surface, If the cable is non-metallic, a metal locating
wire shall also be required and be placed at the same depth as the fiber optic
cable.
Unless otherwise approved by the county, all above-ground appurtenances that
may constitute a roadside obstacle for traffic using the road shall be located as
close as possible to the right of way line. If, due to narrow right-of-way or other
conditions as may be determined by the county, an adjacent to the right-of-way
appurtenance location still constitutes an unacceptable roadside obstacle, said
obstacle must be (a) relocated to another place within the right-of-way, (b)
converted to a break-away design, (c) crash-protected, or (d) relocated to another
location off the road right-of-way. Actions (a), (b) and (c) must be approved by
the county as a condition of permit approval.

Trenched Construction and Backfill:
a.
Where the pavement must be removed, it first shall be cut in vertical (or
undercut) continuous straight lines using appropriate sawing machinery.
Trenches shall be cut to have vertical faces, where soil and depth
conditions permit, with a maximum width of outside diameter of pipe plus
2 feet. Shoring shall comply with the Department of Labor and Industries
Safety Code.
b.
c.
The pipe or carrier shall be installed and the trench backfilled in a
manner assuring no deformation of the pipe likely to cause leakage and
restoration of the structural integrity of the roadway structure. For gravel
surface roads this shall include providing bedding to a depth of six inches
or half the diameter of the pipe, whichever is least. Bedding shall be
approved by the county and consist of granular material free of lumps,
clods, stones, and frozen material. It shall be graded to a firm but
yielding surface without abrupt change in bearing value. Unstable soils
and rock ledges shall be subexcavated from the bedding zone and replaced
with suitable material. Backfill shall be placed in two stages: sidefill to
the level of the top of the pipe, then overfill to the former grade surface.
Sidefill and overfill shall consist of county-approved granular material laid
in six-inch layers, each consolidated by mechanical tamping and controlled
addition of moisture, to a density of ninety-five percent as determined by
AASHTO Method T-99. Consolidation by saturation or ponding is not
permitted. For paved surface roads this shall include the use of Non-
shrink Backfill (see attachment A, Non-shrink backfill specifications).
Bedding, in this case, may be allowed to a maximum of 6 inches over the
top of the pipe.

by means of a vibratory plow may be allowed by the county provided that the
structural integrity of the roadway is not impaired.
UNDERGROUND UTILITIES - ADJUSTMENT
A.
Existing underground utilities on county road right of way shall be either
removed or relocated when road work authorized by the county would cause the
existing underground utility to violate county standards. All such removal or
relocation shall be at the sole expense of the owning utility and all work must
be accomplished by the same permitting process as for new installations.
Notwithstanding reinforcement or protection otherwise provided, a permittee
shall be responsible for the security of each existing pipeline and utility within
a road construction zone, Where there are unusual utility hazards or where
heavy construction equipment will be used, the permittee shall provide adequate
temporary protection, In replacing the roadway, the design should give due
consideration to the protection of previously existing utilities in the roadway
section without sacrificing the geometrics of roadway design.
