Quick Reference Guide to Boulder's Lighting Regulations

• Flood Protection: Lighting panels and distribution equipment must be located at least two feet above base flood elevation in regulated flood hazard areas
• Sign Illumination: Illuminated signs must emit constant intensity light only (no flashing, intermittent, or moving lights)
• Glare Prevention: Lighting must be positioned to prevent glare that could create traffic hazards or nuisances
• Adjacent Properties: Lighting must be shielded to avoid casting direct light on adjacent residential or institutional uses
• Electrical Safety: All wiring and materials for illuminated signs must comply with the State Electrical Code
• Light Strings: Moving devices such as strings of lights cannot be used for advertising purposes

Flood Area Lighting Requirements

Equipment Placement for Flood Protection

In Boulder's regulated flood hazard areas, careful planning for electrical equipment is essential. According to ARM 36.15.901(1)(a), all power service equipment must meet specific elevation requirements:

• All metering equipment, control centers, and transformers must be positioned at least two feet above base flood elevation
• Distribution and lighting panels are subject to the same elevation requirement
• All other stationary electrical equipment must follow this two-foot rule

Why This Matters

This requirement protects critical electrical infrastructure from flood damage while ensuring continuous lighting service during emergencies. Property owners in flood-prone areas should consider these elevation requirements during construction or renovation planning.

Sign Illumination Standards

Constant Light Requirements

Boulder's regulations specifically address how signs can be illuminated to maintain community aesthetics and safety:

• Illuminated signs must emit only light of constant intensity
• Prohibited lighting types include:
• Flashing lights
• Intermittent lights
• Rotating lights
• Moving lights

Positioning and Glare Prevention

How lighting is directed matters as much as the type of lighting:

• Illuminated signs and lighting devices must not cause glare or reflection that could constitute a traffic hazard
• Lighting should be positioned to avoid creating nuisances for neighboring properties
• Signs must be designed with attention to preventing glare while promoting traffic safety

Electrical Compliance

Safety is paramount in Boulder's lighting regulations:

• All wiring, fittings, and materials used in illuminated signs must comply with the State Electrical Code
• This requirement ensures both aesthetic standards and public safety

Protection of Adjacent Properties

Shielding Requirements

Boulder's regulations show particular concern for how lighting affects neighboring properties:

• Lighting must be shielded to avoid casting direct light on adjacent residential uses
• Similar shielding is required when lighting is near institutional uses providing human care
• This consideration aligns with Boulder's community values of respecting neighbors' quality of life

Zoning Goals for Light

The town's zoning regulations explicitly state a goal to "protect existing property by requiring that development affords adequate light, air and privacy for persons living and working within the municipality."

This reflects Boulder's commitment to:

• Ensuring access to natural light
• Preventing excessive light trespass between properties
• Maintaining quality of life for all residents

Decorative Lighting Limitations

Restrictions on Light Strings

While many communities use decorative lighting to enhance commercial areas, Boulder has specific limitations:

• Moving devices such as strings of lights may not be used for the purpose of advertising or attracting attention
• This regulation helps maintain the town's historical character and prevents excessive visual clutter

Balancing Aesthetics and Function

These limitations don't prohibit all decorative lighting but rather focus on preventing lighting that could detract from Boulder's small-town atmosphere or create distractions.

What Property Owners Should Know
