A. General: All plans for street lighting shall be designed by an Illinois registered professional engineer.
The subdivider and/or his project engineer shall be held responsible for coordinating all phases of the work and correcting any deficiencies to the satisfaction of the Village Engineer.
The Village Engineer must be notified at least forty eight (48) hours before any construction is to begin.
The plans shall include a time schedule or other schedule, setting forth when the street lights will be installed by the subdivider and such schedule shall be subject to approval by the Village Engineer. However, in all cases, the street lights shall be installed and operable prior to the issuance of any occupancy permits.
The street light plan shall be provided to the Village Engineer in electronic format.
B. Installation:
1. Location: There shall be at least one street light on each intersection, curve, cul-de-sac, and at other points as may be required in the public interest in unusual or special conditions. They shall be located on the property lines and on the same side of the street as the sanitary sewer wherever possible, and shall be set three feet (3') from the back of curb to face of pole. The streetlights shall be placed opposite of fire hydrant locations wherever possible.
2. Line Drop: Voltage drop shall be no greater than three percent (3%) from power supply to last unit with no wire size smaller than #6 and no larger than #2 type RHH or RHW underground service cable (USE). All street lights shall operate on one hundred twenty (120) volts.

4. Power Supply Connection: Connections to power supply shall be made by Commonwealth Edison Company.
5. Conduit: All existing driveways, street, and sidewalk crossovers shall have one and one-half inch (11/2") galvanized rigid steel conduit used as raceways for underground cable. Heavy duty PVC or A85 conduit will be allowed if it is encased in a three inch (3") minimum concrete collar.
6. Underground Cable: All underground cable shall be placed in unit duct and buried at least thirty inches (30") below the normal finished grade. A red plastic marking tape shall be placed in the trench fifteen inches (15") below finished grade.
7. Splices: All cable on the underground cable section shall be continuous and no splicing shall be made underground. All necessary splices shall be made above ground level.
8. Underground Cable Location: Underground cable shall be installed in a trench not more than two feet (2') from the "back" edge of the curb except that in no case shall the underground cable be installed under a sidewalk.
9. Grounding: Each street light fixture must be ground at the pole; an acorn ground connection shall be provided with a ground rod and #8 copper wire minimum. In addition, the grounding of the street light fixture and arm shall also be in accordance with the adopted Electrical Code.
Each pole shall be connected to the ground by means of a copper wire of the #10 size and shall be welded to the inside wall of the pole and connected to a five-eighths inch (5/8") diameter, eight foot (8') long copper clad steel ground rod. The upper end of the ground rod shall be at least one foot (1') below finished grade.
10. Fusing: All underground feeders shall be fused at or below their rated capacity. Each standard shall contain Tron in-line fuse holders with rubber boots and proper fusing in series with each underground conductor to protect the luminaire located on that pole.
11. Street Light Standard: The lighting pole for all types of streets shall be as specified in table 12-11-I-9 of this subsection:
