Lighting for public or private streets located within or adjacent to a subdivision or development shall be a required public improvement of the subdivision or development.
(A) All work required under this section shall conform to the requirements of the National Electric Code, latest edition and with the service rules and policies of Commonwealth Edison. General electrical requirements, wireway and conduit systems, wire and cable, luminaires, controllers, light poles, foundations and breakaway devices, and the removal and relocation of street lighting facilities shall be constructed in accordance with IDOT's Standard Specifications for Road and Bridge Construction.
(B) Collector streets and arterial streets shall be illuminated in accordance with the latest edition of RP-8, the American National Standard Practice for Roadway Lighting, published by the Illuminating Engineering Society of North America (IESNA). Photometric calculations shall be submitted to the Director of Public Works and Engineering or authorized designee for review and approval. Pole arrangement and pole spacing will be determined by the approved photometric calculations.
(C) Local streets shall be illuminated with standard City of Lockport light poles and luminaires. Poles shall be installed at all intersections, alley entrances, curves, cul-de-sacs, and at the end of a street, with additional poles installed as needed to provide a maximum pole spacing of 360 feet. Unless otherwise directed by the Director of Public Works and Engineering or authorized designee, light poles shall be located on the same side of a street.
(D) Except at intersections, light poles shall be located in line with side property lines. The center of light poles shall be located at least three feet from the back of curb. Light poles located less than six feet from the back of curb shall be provided with breakaway devices. Light poles shall not be located within five feet of a fire hydrant.
(E) Light poles and luminaires for collector streets and arterial streets shall comply with IDOT requirements, and shall be approved by the Director of Public Works and Engineering or authorized designee. Luminaires for local streets shall be either high pressure sodium (HPS) or light emitting diode (LED) and shall comply with City of Lockport requirements.
(F) Light pole foundations shall be Portland cement concrete or helical steel of sufficient depth and diameter. The use of butt-end direct-bury poles is not permitted.
(G) All light poles shall be provided with a ground rod (grounding electrode) connected to the pole ground lug with an insulated conductor.
(H) Quick disconnect tron-type fuse holders shall be provided on power and neutral pole wires inside the light pole handhole. Power cables shall be protected with ten amp fuses and neutral cables shall be provided with a slug.
(I) Light poles at the entrance to a subdivision adjacent to a major street shall be provided with twin fixture arms and two luminaires.
(J) Pole wire shall be THHN, 600-volt stranded copper, single conductor, minimum No. 10 AWG. Underground cable shall be XLP-Type USE, 600-volt stranded copper, single conductor, minimum No. 8 AWG. Cable and wire insulation shall be colored red or black for power, white for neutral and green for ground. Voltage drop calculations shall be submitted to the Director of Public Works and Engineering or authorized designee for review and approval. All wire and cable shall be subject to an insulation test to ground after installation. The minimum acceptable resistance to ground shall be 250,000 ohms. Any section of wiring failing to pass the minimum insulation test, or that shows an obvious short circuit, shall be removed and replaced.
(K) All underground wiring shall be located in HDPE, PVC or galvanized steel duct/conduit. Conduits shall retain 60% void space and conduit sizing calculations shall be submitted to the Director of Public Works and Engineering or authorized designee for review and approval. Conduit trenches shall provide at least 30 inches of cover.
(L) Street lights must be provided with an electrical disconnect located between the light pole and the Commonwealth Edison transformer. The electrical disconnect shall include a circuit breaker located in a NEMA 3R enclosure. Enclosures shall be provided with a padlock, keyed to meet city specifications.
(M) An accurate representation of the street light system shall be included on the subdivision or development as-built plans submitted to the city for review and approval.
