Exterior Lighting Standards

Preventing Light Trespass

Cottonwood's regulations place clear limits on how much light can spill beyond property boundaries. Reflected glare or light from private exterior lighting cannot exceed 0.5 footcandles at the property line when adjacent to residential parcels. This limit increases to 1 footcandle when bordering commercial or industrial properties.

Fixture Requirements

The town takes a technical approach to ensuring quality lighting:

• All outdoor lighting fixtures must be full cutoff fixtures as defined by the Illuminating Engineering Society of North America (IESNA)
• Exceptions may be granted if the developer can demonstrate that off-site impacts from direct views of bulbs are mitigated by fixture design or location
• Outdoor lighting must be designed to minimize light pollution and conserve energy

Height and Placement Controls

Cottonwood maintains its small-town scale through sensible height restrictions:

• Maximum height for any light pole: 25 feet
• Direct, off-site views of light sources are not permitted (except for approved globe/ornamental fixtures)
• Light fixtures must be designed, located, and shielded to prevent creating hazards or nuisances

Special Use Lighting Requirements

Swimming Pool Illumination

For residential pools, Cottonwood's code is straightforward but strict: "Any outdoor lighting of the pool shall not be permitted to spill or shine upon adjacent properties." This simple requirement helps maintain neighborly relations while allowing residents to enjoy evening swims.

Public Dance Venues

Dance venues have specific illumination requirements that balance safety with atmosphere:

• Dancing areas must maintain minimum illumination of 0.5 footcandles
• All exit areas must be illuminated with at least 1 footcandle at floor level
• Dancing in poorly lit conditions (lights "extinguished, dimmed or turned low") is prohibited

Signage Lighting

For bed and breakfast establishments, signs must be non-illuminated and mounted flat against the wall of the dwelling, with size limited to one square foot.

Mitigation Techniques for Light Control

Approved Methods for Reducing Light Pollution

Cottonwood offers guidance on how to meet its lighting standards:

• Use of lenses, shields, louvers, and prismatic control devices to limit glare and spillage
• Careful selection of fixture types and heights
• Potential limitation on hours of operation if needed to reduce impact on surrounding neighborhoods

Compliance Documentation

The city may require submission of a light distribution plan if deemed necessary to ensure compliance with regulations. This provides flexibility for officials to request additional information for larger or more complex projects.
