A. General Requirements
1. Developers of new subdivisions, commercial, and industrial projects, or major additions thereto, are responsible for the design, materials, and installation costs of all streetlighting on all public streets within and adjacent to their project. This requirement applies to both improved and unimproved public right-of-way, adjacent to development site. The City of Sierra Vista will pay all costs associated with providing ongoing electrical service after the City approves activation of the streetlights.
2. Streetlighting plan approval and expiration parallels site plan and/or subdivision plat approval and expiration and requires re-submittal if the improvement plans are updated.
3. Adherence to the designed pole locations is expected. Exceptions may be granted for shifts up to 10± feet parallel to the roadway due to field conditions. Where underground obstructions are encountered, any shift in pole placement must not interfere with a driveway and/or ADA accessibility. Shifts perpendicular to the roadway from permit locations will not be allowed without an approved plan revision.
4. Private streetlights should be labeled as such. Private streetlights are permitted only on private streets and must conform to all applicable City of Sierra Vista lighting ordinances.
5. These regulations do not apply to private onsite development, which must adhere to Development Code Article 151.11.
B. Design Guidelines
1. The public streetlight system shall be installed in the right-of-way. Where right-of-way is not available and where a public utility easement allows for streetlight equipment, the engineer may design equipment within the easement with approval from the City of Sierra Vista. The developer will be required to provide a new public utility easement, if the existing right-of-way or easement is not sufficient to encompass the new improvements.
2. Streetlight layout and design shall include existing and known future streetlight location information for all streets within and adjacent to the proposed development. Streetlight poles and equipment should be shown with station and offset dimensions. In addition, the following information shall be identified, located, sized, and dimensioned from the center line and/or monument line:
a. Existing and proposed utilities (overhead or underground).
b. Face of curb.
c. Width of sidewalk.
d. Width of any public utility easement (PUE).
e. Edge of right-of-way.
f. Edge of pavement.
f. Driveways and handicapped ramps.
g. Any structures that may interfere with streetlight placement.
3. There should be a minimum of three (3) feet of clearance between streetlight poles and other utilities.
4. Design conflicts shall be resolved by the design engineer to the satisfaction of the electrical utility company and the City. It shall be the design engineer’s responsibility to coordinate conflict resolution with electric utility company facilities, including vertical clearances without compromise to the uniformity in the lighting design.
5. Public streetlighting plans will show luminaire and pole type and lumen levels. Streetlight equipment shall conform to approved manufacturers per current utility company and City standards. For streetlights that will be owned and maintained by the local utility company, Sulphur Springs Valley Electric Cooperative, the developer shall be responsible for coordinating streetlighting design with SSVEC. In all cases, the developer will need to coordinate electrical service design with SSVEC.
6. In an effort to achieve reasonable uniformity, deviations away from the specified point of radius are permitted up to 25 feet. Any further deviation must be documented and based on unusual roadway conditions.
7. All poles are to be located approximately 1-foot behind the sidewalk where the sidewalk abuts the curb. Where the sidewalk is detached to create a landscaped area, poles are to be located within the landscaped area, with an easement of adequate width for the public improvements if insufficient right-of-way is available. In no case shall a streetlight be placed within a sidewalk or multi-use path.
8. In areas where standard vertical curb, roll curb or sidewalk does not exist, all poles shall be centered at least ten (10) feet from the edge of the roadway.
9. A new streetlight conforming to the requirements of this section shall be placed along the public right-of-way at each multi-family residential, commercial, and industrial driveway unless there is an existing streetlight located within 100 feet. Parking lot lights may not be used to meet this requirement unless extraordinary conditions exist, as approved by the City.
10. Efforts shall be made during the design stage to assure that two (2) streetlights are located diagonal across the intersection from each other at each arterial street intersection and one streetlight at all other intersections, unless compliance is infeasible, in which case the required streetlights shall be located as close to the intersection as practicable.
11. All street light poles shall be thirty (30) feet in height, unless otherwise permitted, and shall utilize metal standards. Wooden standards are not permitted.
12. Although the City currently uses high pressure sodium (HPS) streetlights and solar street lights, other new technologies (solar, light emitting diode, etc.) will be considered on a case by case basis. The use of alternative technologies is primarily for use on local streets, with consideration being given to other street classifications.
13. Streetlights shall be fully shielded. Additional back shields will be required for streetlights on arterial and collector roadways which are adjacent to residential zoning districts or residential developments.
C. Arterial Streets
Streetlights shall be placed at all intersections and spaced every 200 to 250 feet using 30,000 lumen high pressure sodium lighting. Arterial streets will be lighted on two sides using staggered spacing. Ideal spacing is 200 to 250 feet along the same side of the street; 100 to 150 feet between streetlights on opposite sides of the street.
D. Collector Streets
Streetlights shall be placed at all intersections and spaced approximately 200 to 250 feet apart using 16,000 lumen high pressure sodium lighting. Collector streets will be lighted on two sides using staggered spacing, unless unusual conditions are present in which case lighting on one side of the street may be permitted. Ideal spacing is 200 to 250 feet along the same side of the street; 100 to 150 feet between streetlights on opposite sides of the street.
E. Local Streets
Streetlights shall be placed at all intersections and spaced approximately 250 feet apart using 9500 lumen high pressure sodium lighting. In residential areas, midblock streetlight poles should be placed within one foot laterally from the divisional property line.
Any public street cul-de-sac having a depth of one hundred fifty (150) feet or greater from the face of the nearest curb of the intersecting street to the cul-de-sac radius point will have a streetlight or lights located in the cul-de-sac.
