Understanding these regulations is essential for property owners, developers, and businesses operating within the township.

Quick Reference Guide: Essential Lighting Requirements

Before diving into specifics, here are the most critical lighting requirements in Williamstown Township:

• Light Trespass Limit: Maximum 0.5 footcandles at property lines (measured 5 feet above ground)
• Maximum Light Intensity: 10 footcandles average
• Minimum Requirements:
• Parking areas: 1.0 footcandle (measured 5 feet above surface)
• Pedestrian areas: 2.0 footcandles (measured 5 feet above surface)
• Fixture Height: Maximum 22 feet from ground to centerline of light source
• Prohibited Fixtures: Mercury vapor fixtures, unshielded wall packs, floodlights
• After-Hours Lighting: Non-essential lighting must be turned off after business hours
• Sign Illumination: Must be shielded, directed solely at the sign, or internal to it

General Lighting Standards

Shielding and Placement Requirements

Williamstown Township places significant emphasis on proper light shielding to preserve its rural night sky and prevent nuisance to neighboring properties.

All outdoor lighting must be shielded to prevent light from projecting above a 90-degree horizontal plane. This requirement helps prevent sky glow that can diminish visibility of the night sky, an important aspect of maintaining the township's rural character.

Lighting must be placed and shielded to direct light onto the intended site and away from adjoining properties. The lighting source should not be directly visible from neighboring properties.

Intensity and Measurement Standards

The township has established clear standards for light intensity to ensure adequate illumination without excessive brightness:

• Maximum average light intensity: 10 footcandles
• Minimum parking area illumination: 1.0 footcandle (measured 5 feet above surface)
• Minimum pedestrian area illumination: 2.0 footcandles (measured 5 feet above surface)
• Property line light trespass limit: 0.5 footcandles (measured 5 feet above ground)

Business Hours and Non-Essential Lighting

To conserve energy and reduce unnecessary light pollution, non-essential lighting must be turned off after business hours, leaving only the lighting necessary for site security.

This requirement aligns with the township's values of environmental stewardship while maintaining necessary security measures.

Height and Placement Regulations

Fixture height and placement are regulated to ensure appropriate lighting coverage without creating excessive glare:
