The purpose of this manual is to establish standards for the design and installation of street
lighting in the City of Glendale in order to provide adequate and uniform lighting of streets
and other travel-ways.

The developer should become familiar with these procedures in order to expedite approval of
plans. Any questions concerning street lighting may be addressed by calling the
Transportation Department, Streetlight Management at 930-2940.

Under the provisions of the Glendale City Code, developers of residential subdivisions,
apartments, condominiums, commercial/industrial projects, etc., are responsible for all design
and installation costs of street lighting on public streets peripheral to their projects.

The developer shall retain a professional engineer of the appropriate discipline, registered in the
State of Arizona, to prepare the lighting system design and appropriate calculations relative to
illumination levels. Illumination design shall follow the recommendation of the American
National Standard Practice for Roadway Lighting, Illuminating Engineering Society of North
America (IES), IES RP-8. 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

                                    Glendale, Arizona 85301

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.
