A.  Purpose. The purpose of this chapter is to establish comprehensive provisions for outdoor lighting within Pinal County. This document intends to achieve a balance between safety and aesthetics, to encourage designs that provide for the proper quality and quantity of nighttime illumination, while managing energy consumption, and minimizing light trespass and negative impacts on the surrounding areas and our night sky. Proper exterior lighting design creates lighting systems that are sensitive to the surrounding areas by confining the illumination as much as possible within the boundaries of the project site. It also provides appropriate quantities and uniformity of both horizontal and vertical illumination on the site while minimizing energy usage. This will involve the use of not only the appropriate fixtures and light sources, but also proper placement and operating schedules.

Pinal County recognizes the intent of the International Dark-Sky Association, the Recommended Practices and Design Guidelines put forth by the Illuminating Engineering Society of North America (IESNA), and the requirements and limitations of the International Energy Conservation Code (IECC), and has used these as guiding principles in the development of this chapter. More information can be acquired by obtaining copies of the most recent IESNA and IECC publications.

B.  Applicability. This chapter applies to all new and replacement lighting to be installed at all residential and nonresidential facilities/sites, or the existing lighting at a facility/site that is undergoing a change in use. In the event that a lighting renovation affects more than 50 percent of the facility/site lighting, then the entire facility/site shall be brought into compliance with this chapter. Single-family residences, attached and detached, are subject to PCDSC 2.195.040(L) through 2.195.090 only. In the event an attached or detached single-family dwelling family is on the same parcel as a multifamily commercial or industrial use, the requirements for the multifamily commercial or industrial use shall apply.

C.  Conformance with Applicable Law. All outdoor illuminating devices shall be installed in conformance with the provisions of this chapter, Pinal County subdivision regulations, and any building, zoning or energy codes now in effect or which may hereafter be enacted, as applicable. Where any provisions of any of the Arizona Revised Statutes, federal law, or other Pinal County ordinances or regulations conflict with the requirements of this chapter, the most restrictive shall govern.

D.  Approved Material and Methods of Installation. The provisions of this chapter are not intended to prevent the use of any material or method of installation not specifically prescribed by this chapter, provided any such alternate has been approved. The planning director may approve any such alternate, provided he or she finds that the proposed design, material or method:

1.  Provides approximate equivalence to those specific requirements of this chapter; or

2.  Is otherwise satisfactory and complies with the intent of this chapter.

E.  As new lighting technology develops which is useful in reducing energy consumption, light pollution, and light trespass, consideration shall be given to use of state of the art technology in keeping with the intent of this chapter.

F.  In certain sections of this chapter a lumen requirement is followed by incandescent equivalent in parenthesis. This is for an example only. The lumen requirement shall apply. [Ord. PZ-C-003-09 § 1].

2.195.020 Definitions.

The following words, terms and phrases when used in this chapter shall have the meanings ascribed to them below, except when the context clearly indicates a different meaning:

Abandonment” is the discontinuation of use for a period of one year or more.

Areas, equestrian/roping” is an improved area, generally fenced, of at least 30 feet in width or length within which equestrian activities involving horse riding or driving occurs that are noncommercial in nature and do not include seating.

Arenas, equestrian/roping” is commercially utilized structure or area, sometimes with tiers of seating rising around an improved area, of at least 30 feet in width or length within which equestrian activities involving horse riding or driving occurs.

Bollard, louvered” is a ground-mounted luminaire that is usually 36 inches to 48 inches in height, is generally used for the lighting of paths and building entries, and possesses a stacked set of external angled visors/louvers that minimize direct view of the light source. In order to qualify as a louvered bollard under this chapter, the stacked visors must be positioned/angled in such a fashion as to prevent any direct view of the light source from viewing angles of 90 degrees and above.

Fascia” is the vertical element found around the perimeter of a canopy structure.

Footcandle (FC or VFC)” is a unit of the illumination being produced on a surface, and defined as one lumen per square foot of area illuminated. Footcandle or FC is a general term for all types of illumination, while vertical footcandles (VFC) refers only to illumination being produced on a vertical surface (facade of a building) or passing over a property line (spill light/light trespass).

General illumination” is outdoor lighting used for, but not limited to, illumination for walkways, roadways, equipment yards, parking lots, and outdoor security where safety or security of the grounds is the primary concern.

Glare” is the sensation produced by a bright light source within the visual field that is sufficiently brighter than the level to which the eyes are adjusted, causing discomfort and/or loss in visual performance or visibility.

House-side shield (HSS)” is a visor or louver that is internal or external to a luminaire, that physically blocks and thereby reduces the amount of illuminance being produced to the rear of the luminaire (usually toward residential properties).

Illuminance” is the amount of light falling onto a surface area, measured in footcandles (lumens per square foot) or lux (lumens per square meter). For conversion purposes, one footcandle (FC) is equal to 10.76 lux (lx).

Illuminating Engineering Society of North America (IESNA)” is the nonprofit society established in 1906 whose goal is to improve the lighted environment by bringing together those with lighting knowledge and by translating that knowledge into actions that benefit the public. The IESNA is the primary source of lighting “recommended practices” in North America.

Individual” shall mean any private individual, tenant, lessee, owner or any commercial entity including but not limited to companies, partnerships, joint ventures or corporations.

Installed” means the attaching or assembling in place of any luminaire.

Kelvin” is the temperature scale utilized in illumination science to describe the hue/color of the light. A lower value such as 2,700 Kelvin is associated with a “warm” colored light source such as incandescent, while a higher value such as 4,000 Kelvin is associated with a “cool” colored light source such as metal halide.

Lamp, coated” is the correct term for a light source, such as incandescent or metal halide lamps. “Coated” lamps have an outer coating that minimizes direct view of the arc tube.

Lighting power density (LPD)” is defined as the watts of exterior lighting per square foot of area (watts/ft2) for the different sections of the project site (parking lot, walkways, building entries, etc.). This is the metric established by the International Energy Conservation Code (IECC), and will therefore be utilized as one of the factors for determining conformance with the IECC and this chapter.

Light trespass/spill light” is unwanted light that falls outside of the area intended to be lighted. This chapter places limits on the amount of illumination, in footcandles, that shall be allowed to cross a residential property line.

Lumen” is the unit used to measure the total amount of light that is produced by a light source/lamp. All light sources reduce in lumen output the longer that they are operated. “Initial lumens” is a term defined as the amount of light output from a lamp when it is new. “Mean lumens” is a term defined as the average lumen output of a lamp over its life, and is the lumen value utilized in the proper design of lighting systems. A lumen is a unit of standard measurement used to describe how much light is contained in a certain area. One lumen is defined as the luminous flux of light produced by a light source that emits one candela of luminous intensity over a solid angle of one steradian.

Lumen density (LD)” shall be defined as the initial lumens of the lamps/light sources utilized by the exterior lighting per square foot of area (lumens/ft2) for the project site. This metric is another factor that will be utilized for determining compliance with this chapter.

Luminaire” is a complete lighting unit/fixture, including the lamp, ballast, wiring, housing, reflector, lens, and any shielding.

Luminaire cutoff” is a term established by the IESNA that is associated with four different general classifications of luminaires, each with a different amount of allowed high-angle and upward light: non-cutoff, semi-cutoff, cutoff and full-cutoff. Full-cutoff luminaires, which minimize high-angle light and allow no light above the horizontal, shall be required for most uses. Semi-cutoff and cutoff luminaires, which allow for up to five percent and 2.5 percent uplight respectively, shall be allowed for low-wattage decorative/accent lighting for some uses in lighting zones 2 and 3.

 

Examples of full-cutoff pole-mounted and building‑mounted luminaires. The lamp is completely recessed into the luminaire, and the lens is flat. No light is produced above the horizontal.

Examples of cutoff pole-mounted and building-mounted luminaires. The lamp is completely recessed into the luminaire, but the lens sags/curves downward. Up to 2.5% of the light is produced above the horizontal.

Examples of semi-cutoff pole-mounted and building-mounted luminaires. The lamp visibly protrudes downward into a sag/curved lens. Up to 5.0% of the light is produced above the horizontal.

Examples of non-cutoff pole-mounted and building-mounted luminaires (which are not allowed under this chapter). The lamp is substantially exposed. Little or no attempt is made to control the light produced above the horizontal.

Luminaire, fully shielded” is a fully shielded fixture that is shielded in such a manner that light rays emitted by the fixture, either directly from the lamp or indirectly from the fixture, are projected below a horizontal plane running through the lowest point on the fixture where light is emitted.

Luminaire, partially shielded” is a partially shielded fixture that is shielded in such a manner that the bottom edge of the shield is below the plane of the center line of the lamp reducing light above the horizontal.

Outdoor lighting” is any lighting not within a completely enclosed building.

Outdoor luminaires/light fixtures” are outdoor electric illuminating devices, fixtures, lamps and other devices, searchlights, spotlights or floodlights, permanently installed or portable, used for illumination, emergency, security or commercial purposes. Such devices shall include, but are not limited to, lights for:

A.  Parking lots;

B.  Roadways;

C.  Driveways;

D.  Buildings and structures;

E.  Recreational areas and facilities;

F.  Landscaping decorative effects;

G.  Billboards and signs (advertising and other);

H.  Product display areas;

I.  Gas station lighting; and

J.  Automotive dealership lighting.

Outdoor recreational facility” is an area designed for active recreation, whether publicly or privately owned, including but not limited to: parks, sports fields, sport courts, golf courses, and roping/equestrian arenas.

Residential lighting” refers to outdoor lighting for single or multiple household dwellings.

Security lighting” refers to luminaires that operate dusk-to-dawn in order to provide for protection of property and safety for individuals. They shall conform to all sections of this chapter, and shall generate less than 50 percent of the lighting power density or lumen density utilized by the facility/site during normal business hours.

Skyglow” is the brightening of the sky caused by outdoor lighting, atmospheric factors, and celestial factors. Excessive skyglow interferes with astronomical observations and the enjoyment of the night sky, and this chapter includes several requirements and limitations that help to minimize skyglow.

Uplighting” is any light source that does not have an opaque covering on top.

Use, nonresidential” is the use of land for a purpose other than single-family dwelling units or multiple household dwellings. This definition includes parks with residential zoning.

Watt” is the unit used to measure the electrical power consumption (not the light output) of a light source/lamp. [Ord. PZ-C-003-09 § 1].

2.195.030 General requirements.

A.  Lighting Zones. In order to be more responsive to the special needs of different portions of the county, a system of three different “lighting zones” has been established based upon the current and/or planned uses and ambient brightness of the area. Each “lighting zone” will have different development requirements and lighting restrictions.

Lighting Zone 1: Low ambient light areas, found in zoning districts: CAR, CR-1, CR-1A, CR-2, CR-3, GR, GR-5, GR-10, SH, SR, MH, RU-10, RU-5, RU-3.3, RU-2, RU-1.25, RU-C, R-43, R-35, R-20, R-12, R-9, R-7 and MH-8. Outdoor lighting in this lighting zone shall not exceed 50 percent of the maximum lighting power density (LPD) limits established in the currently adopted version of the International Energy Conservation Code (IECC), or a lumen density (LD) of nine lumens per square foot, whichever is less.

Lighting Zone 2: Medium ambient light areas, found in zoning districts CB-1, CR-4, CR-5, MHP, PM/RVP, RV, TR, MD, MR, O-1, O-2, C-1, MH-435, PM/RV-435. Outdoor lighting in this lighting zone shall not exceed 75 percent of the maximum lighting power density (LPD) limits established in the currently adopted version of the International Energy Conservation Code (IECC), or a lumen density (LD) of 14 lumens per square foot, whichever is less.

Lighting Zone 3: High ambient light areas, found in zoning districts: CB-2, CI-1, CI-2, CI-B, AC-1, AC-2, AC-3, C-2, C-3, I-1, I-2, I-3. Outdoor lighting in this lighting zone shall not exceed 100 percent of the maximum lighting power density (LPD) limits established in the currently adopted version of the International Energy Conservation Code (IECC), or a lumen density (LD) of 19 lumens per square foot, whichever is less.

Note: In the event that a new lighting zone 3 site, or an existing lighting zone 3 site that is undergoing a renovation (as per PCDSC 2.195.010(B)), is to be located within 150 feet of an existing lighting zone 1 site, then the lighting zone 3 site shall be considered a lighting zone 2 site for the purpose of conformance to this chapter.

B.  Operating Hours. Every project in all lighting zones shall be encouraged to reduce as much as possible the amount of outdoor lighting that operates after 10:00 p.m., except as permitted in PCDSC 2.195.040. All nonsecurity lighting (except for the illumination of roadways and state and federal flags) shall be turned off by 10:00 p.m. or within one hour after close-of-business, whichever is later. A nighttime reduction of at least 50 percent in overall LD or LPD is required. All non-full cutoff luminaires in lighting zones 1 and 2 shall be included in the fixtures being turned off.

Non-full-cutoff and nonfully shielded incandescent luminaires of greater than 150 watts, and all other luminaire types of greater than 70 watts, that were installed prior to the adoption of the chapter are considered to be nonconforming, and shall possess an automatic control device that turns the luminaires off between midnight and sunrise.

In addition to turning off these nonconforming luminaires, multifamily housing is only required to reduce the lighting located at common areas such as clubhouses, pool areas and playgrounds.

 

C.  Light Sources and Fixture Shielding. New mercury vapor light sources shall not be allowed. Existing installations must be removed or replaced with a conforming light source and luminaire by no later than January 1, 2011.

Searchlights and strobe/flashing lights are not allowed in any lighting zone without a separate permit as required in PCDSC 2.195.090, and the duration of the allowed use may be limited by planning staff.

Lasers, exposed neon, and other intense linear light sources are not allowed in lighting zone 1, but are allowed in lighting zones 2 and 3 and subject to approval and stipulations by planning staff during the review process. Lasers must be aimed at-or-below the horizontal plane and terminated on an opaque surface within the site.

All site perimeter luminaires located within 50 feet of a single-family residential property line, excluding bollards or other luminaires of less than six feet in height, shall possess house-side shielding (HSS) to the satisfaction of planning staff. All such luminaires that will also be operating after 10:00 p.m. shall possess external house-side shielding.

The total amount of outdoor lighting that is not full-cutoff, including uplighting, shall not exceed five percent of the outdoor lighting LPD or LD, whichever is less. Uplighting that is covered by solid roof or solid building overhang will not be subject to this chapter if it is:

1.  Permanently set at 90 degrees; and

2.  Is pulled back from any edge of the solid roof or solid building overhang by a distance equal to the distance between the top of the uplight (X) and the distance between the outside edge of the uplight and the outside edge of the solid roof or solid building overhang (Y).

Lighting Zone 1: Pole- or wall-mounted luminaires shall be full-cutoff luminaires only. Bollards shall be full-cutoff, or louvered with coated lamps (see PCDSC 2.195.020, “Bollard, louvered”). All light sources shall have a maintained color temperature of less than or equal to 3,000 Kelvin.

Wall-mounted luminaires of greater than 800 initial lumens shall possess a bottom-diffusing lens or an internal house-side shield (HSS), to the satisfaction of planning staff, in order to minimize the illuminance “hot spot” on the wall. Uplighting luminaires shall not exceed 800 initial lumens each.

Lighting Zone 2: Pole- or wall-mounted luminaires of less than or equal to 1,800 initial lumens may be semi-cutoff, cutoff, or full-cutoff. All other pole or wall-mounted luminaires shall be full-cutoff. Bollards shall be full-cutoff, or louvered with coated lamps, or of a type where the lamp is recessed and not directly visible.

Wall-mounted full-cutoff luminaires of greater than 3,500 initial lumens shall possess a bottom-diffusing lens or an internal house-side shield to the satisfaction of planning staff. Uplighting luminaires shall not exceed 1,200 initial lumens each.

Lighting Zone 3: Pole- or wall-mounted luminaires of less than or equal to 3,500 initial lumens may be semi-cutoff, cutoff, or full-cutoff. All other pole or wall-mounted luminaires shall be full-cutoff. Bollards shall be full-cutoff, or louvered with coated lamps, or of a type where the lamp is shielded and not directly visible.

Wall-mounted fixtures of greater than 6,500 initial lumens shall possess a bottom-diffusing lens or an internal house-side shield to the satisfaction of planning staff. Uplighting fixtures shall not exceed 1,200 initial lumens each.

D.  Luminaire Mounting Height and Equipment Finish. The mounting height of a luminaire is to be measured from finished grade to the fixture lens or luminous opening. The exposed portion of concrete pole bases shall be finished in a fashion other than exposed concrete (brushed finish, painted, etc.). No portion of any luminaire that is attached to a wall that is common with another property shall be allowed to protrude above the top of the wall. In lighting zones 1 and 2, bollards shall not be more than 48 inches in height.

Lighting Zone 1: Luminaires located at or within 30 feet of a residential property line shall not exceed eight feet in height. All others shall not exceed 15 feet in height, and the pole color shall be dark and nonreflective (such as dark bronze or black).

Lighting Zone 2: Luminaires located at or within 30 feet of a residential property line shall not exceed eight feet in height. Luminaires located greater than 30 feet and less than or equal to 150 feet from a residential property line, and not blocked from direct view by a structure, shall not exceed 15 feet in height. All others shall not exceed 25 feet. Pole color shall be dark and nonreflective (such as dark bronze or black).

Lighting Zone 3: Luminaires located at or within 30 feet of a residential property line shall not exceed eight feet in height. Luminaires located greater than 30 feet and less than or equal to 150 feet from a residential property line, and not blocked from direct view by a structure, shall not exceed 15 feet in height. All others shall not exceed 30 feet in height. Pole color shall be approved by planning staff.

E.  Perimeter (Spill Light) Illuminance Levels. This chapter establishes limits for the amount of light trespass/spill light that is allowed to cross a project site’s property line(s) when there is a residential property line located within 150 feet of any of the project site’s property line(s). These limits are based upon initial maximum vertical illuminance values along the appropriate property lines, calculated at no more than 10-foot horizontal increments, and at an elevation of six feet above finished grade. The calculated “observation point” shall be oriented perpendicular into the project site, and angled at 90 degrees above nadir (perfectly horizontal). The light loss factor (LLF) utilized for the calculations shall be 1.00. The following limits shall not be applied to the permanently exempted uses, or the specific uses in this chapter where alternate spill light limits are expressly defined.

Lighting Zone 1: The maximum initial vertical illuminance at any calculation point shall not exceed 0.30 footcandles during normal business evening hours, and 0.10 footcandles after the facility enters security lighting-only operating mode (in compliance with subsection B of this section).

Lighting Zone 2: The maximum initial vertical illuminance at any calculation point shall not exceed 0.80 footcandles during normal business evening hours, and 0.30 footcandles after the facility enters security-lighting-only operating mode.

Lighting Zone 3: The maximum initial vertical illuminance at any calculation point shall not exceed 1.50 footcandles during normal business evening hours, and 0.80 footcandles after the facility enters security-lighting-only operating mode.

1,800 lumens is equivalent to the initial lumen output of a 100-watt incandescent, or a 26-watt compact fluorescent lamp. 3,500 lumens is equivalent to the initial lumen output of a 42-watt compact fluorescent, or a 50-watt metal halide lamp. 6,500 lumens is equivalent to the initial lumen output of a 70-watt high pressure sodium lamp.

G.T.

Greater than.

L.T.E.

Less than or equal to.

L.T.E. 1,800

A light source that produces less than or equal to 1,800 lumens of light when the lamp is new.

All nonsecurity lighting shall be turned off within two hours after the completion of the last service/event. Any fixtures located within 30 feet of a residential property line shall be included in those being turned off. In the event that the parking lot is sized for peak usage (holidays, etc.), control of the lighting is to be divided into “tiers,” so that the parking lot lighting in the peak-usage areas only operates during those peak times of the year. Uplighting for the illumination of steeples or other towers for religious facilities are not subject to the provisions of this chapter.

G.  Automotive Dealerships. A minimum of 50 percent of the outdoor illumination shall be turned off within one hour after the close of business. All non-full-cutoff fixtures shall be automatically turned off at this time. All perimeter fixtures shall possess house-side shields. Under-canopy lighting shall be full-cutoff, or the canopy fascia shall be extended on all sides so that is lower than any portion of the fixture lens. This use is subject to all other applicable sections in this chapter except for the vertical footcandle (VFC) limits in PCDSC 2.195.030(E).

H.  Equestrian Arenas. All new luminaires mounted at a height of 40 feet or less shall be full-cutoff, and others mounted higher than 40 feet may be sports-style floodlights with exceptional internal and external shielding, to the satisfaction of planning staff.
