General Lighting Principles

Conservation and Safety Balance

Franklin County's approach to lighting embodies a thoughtful balance. The code explicitly states that "lighting practices and systems shall minimize glare and light trespass in order to conserve energy and to limit degradation of the night time visual environment while maintaining night time utility, safety, and security."

Wildlife and Sky Protection

The regulations specifically mention protection of wildlife habitat, demonstrating the county's environmental awareness. Light fixtures must be "located, aimed, or shielded so as to minimize stray light trespassing across property boundaries, upward into the sky, or into wildlife habitat."

Nuisance Prevention

A fundamental principle throughout the code is preventing lighting from becoming a nuisance. No development is permitted to "direct hazardous light, glare, or heat beyond its property line," protecting neighbors from unwanted illumination.

Sign Illumination Standards

Shielding Requirements

For businesses and properties using illuminated signs, Franklin County has established clear guidelines:

• Downward Direction: Direct light must be shielded downward onto the sign
• Containment: Light must not shine into surrounding areas or skyward
• Residential Protection: Signs in commercial and industrial areas may be illuminated but cannot shine into residential areas

Operating Hours

The county balances business needs with dark sky preservation through timing requirements:

• Automatic Shutoff: All illuminated signs must have timers to turn off lights between 10:30 p.m. and 5:00 a.m.
• Late-Night Business Exception: Businesses operating during these hours are exempt but must turn off lights at closing

Prohibited Sign Lighting

Several types of sign lighting are specifically prohibited:

• Flashing/Moving Lights: Signs with blinking, flashing, moving, or scintillating lights are prohibited (with limited exceptions)
• Glare-Producing Signs: Signs with direct rays that cause glare, impair driver vision, or interfere with motor vehicle operation
• Institutional Signs: Identification signs for churches and other institutions must not be illuminated

Conditional Exceptions

Some limited exceptions exist with proper approvals:

• Time-Temperature Signs: May incorporate blinking lights if displaying two public service items (time, temperature, or date) and with conditional use approval
• Rigid Panel Signs: Lights behind permanently affixed translucent panels may be permitted with conditional use approval

Development and Property Lighting

Commercial and Industrial Requirements

The County Development Code requires commercial and industrial developments to mitigate potential nuisances including glare, reflecting the county's commitment to balancing economic growth with quality of life.

Planning Considerations

Site plans submitted for review by the Planning and Zoning Commission must include details on "location and dimension of all entrances, exits, roads, walkways, trails, drainage structures, driveways, and pedestrian/roadway lighting," ensuring lighting is thoughtfully incorporated into development plans.

Protecting Neighbors

The regulations are clear that "No ACO shall direct any lighting that would cause a hazardous situation on any public road or directed to shine in neighboring properties homes," prioritizing both safety and neighborly consideration.

Special Considerations for Airport Areas

Pilot Safety

Properties near airports have additional restrictions: no lighting may "make it difficult for pilots to distinguish between airport lights and other lights, resulting in a glare to the eyes of pilots using the airport, impair visibility in the vicinity of the airport."

Obstruction Marking

In the Airport Overlay Zoning District, the county may require "installation, operation, and maintenance of any markers and/or lights" deemed necessary to indicate obstructions to aircraft pilots.

Street Lighting Requirements

Intersection Illumination

The county requires that "Street lights shall be installed at intersections throughout the subdivision," ensuring safety at these critical roadway junctions.

Compliance with Standards

Developers must "conform to the requirements of the Commission and the public utility providing such lighting," ensuring consistent standards throughout the county.
