(A)Parallel Lines. Underground power and communication lines may be permitted parallel to the centerline of conventional County highways under the following conditions:
The installation shall be located as near the right of way line as practicable and no more than five (5) feet (1.5m) from the right of way line.
Cable may be installed by trenching or plowing with special consideration given to crossing improved entrances and side roads.The applicant for permit shall submit his plans and proposed construction methods.
If the buried electric power cable used it to operate at three hundred (300) volts to ground or greater, it must include a bare grounded conductor in continuous contact with the earth. This conductor shall be adequate for the magnitude and duration of the fault current imposed and shall be either shielded or multiple concentric conductors closely spaced circumferentially.
Above-ground appurtenances constructed as component parts of underground communications or electric power lines shall be located within one (1) foot (0.3m) of the right of way line or as near as practicable.
(B) Underground Crossings. Underground power and communication lines will be permitted to cross County highways under the following conditions:
The design materials and construction methods shall be those that can be expected to provide maximum maintenance-free service life.
Capacity for foreseeable future expansion needs shall be provided in initial installation.
Encasement shall be provided between jacking or bore pits, if the crossing is installed by boring or jacking.
Encasement may be eliminated under the following conditions:
The crossing is installed by the use of “moles”, “whip augers” or other approved method which compress the earth to make the opening for cable installation.
The installation is by the open trench method. This method is only permitted prior to the roadway construction.
If the power cable used is to operate at three hundred (300) volts to ground or greater, it must include a bare grounded conductor in continuous contact with the earth. This conductor shall be adequate for the magnitude and duration of the fault current imposed and shall be either shielded or multiple concentric conductors closely spaced circumferentially.
Installations shall have a minimum cover of thirty (30) inches (0.8m)except that communication lines installed by the plowed method shall have a minimum cover of twenty-four (24) inches (0.6m).
Overhead power and communication lines parallel to the centerline of conventional County highways, where permitted, shall be single pole construction located as near as practicable to the right of way line and as nearly parallel to the right of way line as reasonable pole alignment will permit.
Joint use of poles shall be required where practical.
No utility poles shall be permitted in the ditch line of any County highway.
Ground-mounted appurtenances to electric power or communication lines, when permitted, shall be located within one (1) foot (0.3m) of the right of way line or as near as practicable.
Overhead power and communication line crossing highways shall cross at or as near to a ninety (90) degree angle as practicable. Vertical line clearance over the roadway shall be a minimum of eighteen (18) feet (5.5m) with additional clearances as required by General Order No. 160 Revised of the I.C.C. for higher voltage lines.
Poles shall be located within one (1) foot (0.3m) of the right of way of the highway or as near as practicable.
Overhead crossings at major interchanges shall be discouraged.
In expanding areas, frequent service crossings shall be discouraged in favor of requiring distribution systems on both sides of the highway.
An application for a permit for a new proper or communication installation system shall include evidence, if required, that a “Certificate of Public Convenience and Necessity” has been issued by the Illinois Commerce Commission. Electric power or communications installations on County highway rights of way shall be constructed, operated, and maintained in conformity with the provisions of the National Electric Safety Code and General Order No. 160 Revised of the Illinois Commerce Commission entitled “Rules for Construction of Electric Power and Communication Lines” except for certain vertical clearance requirements as hereinafter noted.
(A) Ground Mounted Appurtenances. Ground mounted appurtenances, when permitted on County highway rights of way, shall be provided with a vegetation-free area extending one (1) foot (305mm) in width beyond the appurtenance in all directions. The vegetation-free area may be provided by an extension of the mounting pad, or by heavy duty plastic or similar material meeting the approval of the Department. With the approval of the district, shrubbery surrounding the appurtenance may be used in place of vegetation-free area. The housing for ground mounted appurtenances shall be painted an inconspicuous color.
(B) Guy Wires and Brace Posts. The utility companies shall make every reasonable effort to design the installation so guys and braces will not be needed on the rights of way.
Exceptions may be allowed when there is no feasible alternative. When an exception is allowed, guy wires shall be equipped with GUYGUARDS for maximum visibility.
