DIVISION 10-08-002. DEVELOPMENT LIGHTING REGULATIONS
10-08-002-0001. INTENT AND PURPOSE
It is the intent of this Division to encourage lighting practices and systems which will: minimize light pollution, glare, light trespass; conserve energy and resources while maintaining night-time safety, utility, security and productivity; and curtail the degradation of the night time visual environment. It is recognized that since topographic and atmospheric conditions surrounding the City of Flagstaff are uniquely suited for astronomical observation and since observatories have been established in the City’s vicinity, the City of Flagstaff, through the provisions herein contained, promotes the reduction of light pollution which interferes with the successful operation of such observatories. The effects of outdoor lighting on the light pollution over the observatories is strongly dependent on the distance of those lights from the observatories; therefore, three Astronomical Zones are hereby established, allowing increased flexibility in the uses of outdoor lighting farther from the observatories.
10-08-002-0002. APPLICABILITY
A.
NEW USES, BUILDINGS AND ADDITIONS: All proposed new land uses, developments, buildings, structures, or building additions of twenty-five (25) percent or more in terms of additional dwelling units, gross floor area, seating capacity, or other units of measurement specified herein, either with a single addition or cumulative additions subsequent to the effective date of this provision, August 5, 1999, shall meet the requirements of this Division for the entire property. This includes additions which increase the total number of required parking spaces by twenty-five (25) percent or more. For all building additions of less than twenty-five (25) percent cumulative, the applicant shall only have to meet the requirements of this Division for any new outdoor lighting provided.
B.
CHANGE OF USE/INTENSITY: Except as provided in subsection C below, whenever the use of any existing building, structure, or premises is changed to a new use, or the intensity of use is increased through the incorporation of additional dwelling units, gross floor area, seating capacity, or other units of measurement specified herein, and which change of use or intensification of use creates a need for an increase in the total number of parking spaces of twenty-five (25) percent or more, either with a single change or cumulative changes subsequent to the effective date of this provision, August 5, 1999, then all outdoor lighting facilities shall meet the requirements of this Division for the entire property, to the maximum extent possible as determined by the Planning Director. For changes of use or intensity which require an increase in parking of less than twenty-five (25) percent cumulative, the applicant shall only have to meet the requirements of this Division for any new outdoor lighting provided.
C.
NONCONFORMING USES, STRUCTURES OR LOTS: Whenever a nonconforming use, structure or lot is abandoned for a period of one hundred eighty (180) consecutive days and then changed to a new use according to the requirements of Sections 10-10-005-0003 and 0004 of this Code, then any existing outdoor lighting shall be reviewed and brought into compliance as necessary for the entire building, structure or premises, to the maximum extent possible as determined by the Planning Director.
10-08-002-0003. APPROVED MATERIALS AND METHODS OF CONSTRUCTION OR INSTALLATION / OPERATION:
A.
Preferred Source – Low-pressure Sodium (LPS) lamps are the preferred illumination source throughout the city; their use is to be encouraged, when not required, for outdoor illumination whenever its use would not be detrimental to the use of the property.
B.
Uses that can turn off their outdoor lighting during night hours are to be encouraged in Astronomical Zone I (Section 10-08-002-0004); those which require all night illumination are to be discouraged.
C.
The provisions of this Division are not intended to prevent the use of any design, material or method of installation or operation not specifically prescribed herein, provided any such alternate has been approved by the Planning Director. The Planning Director may approve any such proposed alternate provided he/she finds that it:
1. Provides at least approximate equivalence to the applicable specific requirements of this Division; and
2. is otherwise satisfactory and complies with the intent of this Division.
10-08-02-0004. ESTABLISHMENT OF ASTRONOMICAL ZONES:
Illustration 10-08-002-0004 showing the established astronomical zones. Click for a larger view.
A.
Three Astronomical Zones are hereby established: Zone I is in two parts centered at the observatories located on Anderson Mesa (Lowell Observatory) and west of Flagstaff (Naval Observatory); the outer boundary of Zone I is set at approximately two and one-half (2.5) miles from these observatories. Zone II extends from the outer boundary of Zone I to approximately seven miles from the observatories. Zone III is all remaining property within the City limits. These Zones are shown in Illustration 10-08-002-0004, the Astronomical Zone Map, and by this reference made a part hereof.
B.
A parcel located in more than one of the described Zones shall be considered to be only in the more restrictive Zone.
10-08-002-0005. GENERAL REQUIREMENTS, ALL ZONES:
A.
Outdoor floodlighting by flood light projection above the horizontal plane is prohibited.
B.
All light fixtures that are required to be shielded shall be installed in such a manner that the shielding is effective as described in Chapter 10-14, Definitions, for fully or partially shielded fixtures.
C.
All light fixtures, except street lights, shall be located, aimed or shielded so as to minimize stray light trespassing across property boundaries.
D.
The installation, sale, offering for sale, lease or purchase of any mercury vapor light fixture or lamp for use as outdoor lighting is prohibited, except that until 1 January 1996, the provisions of this Subsection shall not apply to any replacement bulb.
E.
Search lights, laser source lights, or any similar high-intensity light shall not be permitted, except in emergencies by police and fire personnel or at their direction; or for meteorological data gathering purposes.
F.
Class 1 lighting may continue only until 9:00 pm or for as long as the area is in active use. See Table 10-08-002-0005 and Chapter 10-14, DEFINITIONS, for an explanation and use of the different classes of lighting.
G.
Any lamp type that has been determined to emit substantial non-visible radiation, as determined from manufacturer’s specifications or photometric test, requires a filter that blocks this non-visible radiation. Examples of such lamps include, but are not limited to, Quartz-Halogen and fluorescent. For infrared security lighting, see Section 10-08-002-0010.
H.
Illumination for outdoor recreation facilities must conform to the shielding requirements of Table 10-08-002-0005 below, except when such shielding would interfere with the intended activity. For such facilities, partially-shielded luminaires are permitted. Examples of activities where partially-shielded luminaires are permitted include, but are not limited to, baseball, softball, and football. Specifically, tennis, volleyball, raquetball and handball courts and swimming pools must utilize fully-shielded luminaires. Where fully-shielded luminaires are required, the light fixtures must also conform to the requirements of Subsection C above regarding light trespass.
I.
Multi-class lighting must either conform to the lamp-type and shielding requirements of the most strict class, as shown in Table 10-08-002-0005, or conform to the time limitations of the least strict class.
J.
External illumination for signs shall conform to the provisions of this Division.
K.
On projects where an engineer or architect is required, the developer shall verify in writing to the City that all outdoor lighting was installed in accordance with the approved plans.
L.
Outdoor Light Output, Total. The maximum total amount of light, measured in lumens, from all outdoor light fixtures. For lamp types that vary in their output as they age (such as high pressure sodium), the initial output, as defined by the manufacturer, is the value to be considered. For determining compliance with sections 10-08-002-0006A, -0007A and -0008A of this Division, the light emitted from outdoor light fixtures is to be included in the total output as follows:
1. Outdoor light fixtures installed on poles (such as parking lot luminaires) and light fixtures installed on the sides of buildings or other structures, when not shielded from above by the structure itself as defined in paragraphs 2 and 3 below, are to be included in the total outdoor light output by simply adding the lumen outputs of the lamps used;
2. Outdoor light fixtures installed under canopies, building overhangs, or roof eaves where the center of the lamp or luminaire is located at least five (5) feet but less than ten (10) feet from the nearest edge of the canopy or overhang are to be included in the total outdoor light output as though they produced only one-quarter (1/4) of the lamp’s rated lumen output;
3. Outdoor light fixtures located under the canopy and ten (10) or more feet from the nearest edge of a canopy, building overhang, or eave are to be included in the total outdoor light output as though they produced only one-tenth (1/10) of the lamp’s rated lumen output.
M.
Service Station Canopy Lighting. In addition to the calculations for paragraph L.2 and 3 above, the following requirements apply to service station canopies:
1. All luminaires mounted on the under surface of service station canopies shall be fully shielded and utilize flat glass or flat plastic (acrylic or polycarbonate) covers.
2. The total light output used for illuminating service station canopies, defined as the sum of all under-canopy initial bare-lamp outputs in lumens, shall not exceed forty (40) lumens per square foot of canopy in Zones II and III, and shall not exceed twenty (20) lumens per square foot in Zone I. All lighting mounted under the canopy, including but not limited to luminaires mounted on the lower surface of the canopy and auxiliary lighting within signage or panels over the pumps, is to be included toward the total.
N.
Neon lighting is permitted, so long as lumen calculations from such lighting are included in the total lumen calculations for the site, required by this section. Lumens are calculated on a per foot basis, rather than per “fixture.” Such lighting shall also be subject to the shielding requirements of this section, unless exempted by Table 10-08-002-0005.
