13-12-005-0002 Streetlight Support Structures
Streetlight support structures consist of the base, pole, and mast arms. The standards of construction for streetlight equipment shall follow those of Arizona Public Service (APS) Construction Standard Drawing No. 8040. The streetlight pole, mast arm, and luminaire assembly shall be in accordance with AASHTO Standard Specifications for Structural Supports for Highway Signs, Luminaires and Traffic Signals (2001 Design Criteria), to withstand a wind speed of ninety (90) miles per hour.
Contact APS for a copy of the current construction standards.
The geometry of the support structure varies with the luminaire size as shown in Table 13-12-005-02:

Mast arms of different rise and length may be required when existing utility poles are utilized. The design of the mounting and mast arm chosen shall be such as to place the luminaire at the appropriate nominal mounting height and above the curb or edge of the pavement of the street. (Ord. 2017-22, Rep&ReEn, 07/05/2017)
13-12-005-0003 Structure Colors and Paint Specifications
The City Engineer will evaluate new projects that have streetlights to determine whether the support structure and luminaire will be colored. If it is so determined, then the following will apply:
A. Poles and mast arms shall be galvanized inside and out. The surfaces to be painted shall be acid washed and cleaned prior to painting. Galvanized coatings on surfaces not being painted shall be protected from the acid wash.
B. Painting and priming of luminaire and other fixture housings shall be done in accordance with the requirements of ADOT Standard Specification Sections 610 and 1002.
C. The color of the support structure shall match Sherwin-Williams Drylac RAL6012 or approved equal. Alternate colors may be acceptable if approved by the City Engineer.
D. Supplementary pedestrian level lighting structures and luminaire may be finished in other colors providing that the color chosen is sensitive to and complements the environment surrounding the installation. (Ord. 2017-22, Rep&ReEn, 07/05/2017)
13-12-005-0004 Streetlight Equipment and Service Line Ownership
A. For streetlights on public roadways, the division point for ownership is at the junction point where the service line is tapped or spliced for the service to each light. Thus, the streetlight equipment including foundation, pole, mast arm, luminaire, and wiring within each pole and to the junction point, are property of the City of Flagstaff. The electric circuit feeding the lights, the junction box at the foot of each pole, and the connections, splicing, fuses, and other equipment within the junction box are the property and responsibility of the electrical utility that provides power to the streetlights.
B. On private streets, the streetlight ownership, operation, and maintenance are by separate agreement with the utility and the homeowners’ association, entity, or organization responsible for the private street. (Ord. 2017-22, Rep&ReEn, 07/05/2017)
