The luminance criteria, with light loss factors of.76 (HPS), shall be used to determine conformity with IES and city street lighting design guidelines. Street lighting plans shall be submitted at the service counter at the Development Services Center (second floor, Municipal Building) or by mail/carrier addressed to: City of Glendale Development Services Center 5850 West Glendale Avenue Glendale, Arizona The developer shall submit six (6) sets of plans, specifications and electrical engineering requirements for the first review. Once final review has been completed, six (6) sets of plans, specifications, material quantities and product literature shall be submitted for approval. Approval is limited to six (6) months and may be renewed for another six (6) months if requirements have not changed. When the plans have been stamped approved, the four (4) sets will be distributed as follows: 1- the utility company (by the Streetlight Management) 1- Building Safety 1- Street Lighting (Streetlight Management) 1- retained for streetlight contractor The developer shall pay all related permit and power connection fees and is responsible for notifying the electric utility company of any design changes, affecting power service and/or common trench. Design conflicts shall be resolved by the developer to the satisfaction of the electrical utility company. It shall be the developer s responsibility to coordinate conflicts with all electric utility company equipment without compromise to the uniformity in the lighting design. 9

11 The installation and inspection of street lighting shall be accomplished in a timely manner. A final inspection of the streetlight installation will be accomplished by the City of Glendale Transportation and Building Safety Departments. If necessary, a list of discrepancies will be submitted to the contractor for corrective action. When corrective action has been accomplished, to the satisfaction of the City, approval for power connection will be transmitted to the electric utility company by the Transportation Department. All streetlights shall be connected to the permanent power supply and functioning properly before final acceptance of the street lighting installation. The developer shall be responsible for the actions of the contractor installing the street lighting system. 10
