Marana Outdoor Lighting Code
2003
Section 1. Purpose and Intent. The purpose of this code is to preserve the relationship of the
residents of Marana with their unique desert environment through protection of access to the
dark night sky. Intended outcomes include continuing support of astronomical activity,
minimizing wasted energy, and reduction of intrusive glare, while not compromising the safety,
security and well being of persons engaged in outdoor nighttime activities.
It is the intent of this Code to control the obtrusive aspects of excessive and careless outdoor
lighting usage while preserving, protecting, and enhancing the lawful nighttime use and
enjoyment of any and all property. It is recognized that portions of properties may be
required to be unlit or have reduced lighting levels or be covered in order to allow enough
lumens in the lighted areas to achieve light levels in accordance with nationally recognized
recommended practices.
Section 2. Conformance with Applicable Coden. All outdoor illuminating devices shall be
installed in conformance with the provisions of this Code, the Building Code, the Electrical
Code, the Sign Code, any ordinances and rulings of the Town Council as applicable, and under
appropriate permit and inspection. See Section 15 for definitions of terms specific to this Code.
Section 3. Applicability

fixtures being replaced shall not be included in the lumen calculations, but the total of non-
conforming lighting shall not be increased.
3.2. Existing Installations. All other outdoor light fixtures lawfully installed prior to and
operable on the effective date of the ordinance codified in this chapter are exempt from all
requirements of this Code. The installation shall be maintained in accordance with the edition of
the Outdoor Lighting Code under which it was installed.

fixtures limited to 2000 lumens per site.
2. All commercial outdoor lighting within 25 feet of residential areas shall have external
house-side shields or forward throw optical characteristics. Additional shielding may be
required by the Building Official when glare intrudes into residential areas or affects
visibility of traffic signals or signage.
3. Flood or spot lamps shall be aimed no higher than 45 degrees to the horizontal (half-way
between straight down and straight to the side). The source shall not be visible fi.om any
adjacent residential property. The lamp shall have the means to permanently aim the
lamp.
4. Light trespass into residential areas shall not exceed 0.3 fc measured vertically at 5 feet
above the ground.
5. Seasonal decorations using unshielded low-wattage incandescent lamps (50 watt
maximum) shall be permitted from Thanksgiving to January 15th.
5.2 Outdoor Light Fixture Height Requirements.
1. The height of a pole-mounted luminaire shall be measured fi.om finished grade to the
bottom of the lens ofa luminaire and the poles shall not extend more than 2 feet
above the bottom of the lens for any purpose.

4. All wall mounted luminaries utilizing lamps in excess of 4,000 lumens and/or installed
above 9 feet in elevation shall be equipped with an internal house-side shield or provided
with similar forward throw optical characteristics so as to minimize the reflected light off
the wall below the luminaire. See section 5.1 #2 for other restrictions.
Section 6. Total Light Output Values Per Site
The total amount of light, measured in lumens, is limited to a value per net acre of the site. The
output fi.om all outdoor light fixture lamps, shall be determined as follows:
1. For lamp types that vary in light output as they age (such as fluorescent and high
intensity discharge lamps), the mean lumen output, as defined by the lamp manufacturer,
shall be the lumen value used. For lamps not listed with mean lumens, the initial rating
shall be used.
- 4
2. The light output of each outdoor light fixture shall be based on the largest lamp that
the outdoor light fixture is rated to accommodate. Furthermore, the largest lamp rating
for fluorescent and high intensity discharge fixtures shall be based on the installed ballast
rating.
6.1 Total outdoor light output shall not exceed the lumen limits given in Table 6. In the table,
Total means the sum of emitted light on the site. For determining compliance with Section 6, the
total lumens shall be the sum of the following:
1. One hundred percent of the lumens from outdoor light fixtures installed on grade, on poles,
and installed on the top or sides of buildings or other structures, when not shielded from
above by the structure itself.
2. Fifty percent of the lumens from underwater light fixtures unless the fixture is aimed at
an angle of less than 45 degrees above the horizontal, in which case the lumens shall be
calculated at 10% of the lumens.
3. Zero percent of full cutoff light fixtures installed under canopies, building overhangs, or
mol eaves in such a manner that no lamp or vertical element of a lens or diffuser is visible
at the property line.
4. Twenty percent of full cutoff light fixtures installed under canopies, bnilding overhangs or
roof eaves that can be seen fi'om the property line.
5. Zero percent of internally illuminated signs or lights illuminating a US flag when shining
downward.
