Lighting Regulations in Guthrie, Oklahoma: Balancing Historic Character with Modern Illumination

Introduction

Nestled in central Oklahoma, Guthrie stands as a testament to America's pioneering spirit. Founded during the Land Run of 1889, this historic city rapidly grew from unsettled territory to a thriving community of 10,000 people. Today, Guthrie boasts one of the largest historic districts on the National Register of Historic Places, encompassing over 2,000 buildings across 1,400 acres.

The city's commitment to preserving its architectural heritage while embracing necessary modern advancements is reflected in its approach to lighting regulations. These guidelines serve a dual purpose: maintaining the historical ambiance that defines Guthrie while ensuring safety and functionality for residents and visitors alike.

Let's explore the specific lighting requirements that property owners, businesses, and residents need to understand when illuminating properties in this historically significant community.

Quick Reference Guide: Key Lighting Requirements

• Nighttime digital brightness: 500 NITs maximum (from half-hour after sunset to half-hour before sunrise)
• Daytime digital brightness: 6,500 NITs maximum (half-hour before sunrise to half-hour after sunset)

Mobile Home Parks:

• Street lighting must meet Illuminating Engineering Society standards or minimum 0.5 candlepower (whichever is higher)
• Each mobile home space requires a 100-ampere electrical outlet

Towers and Security Lighting:

• Tower illumination prohibited except when required by FAA
• No strobes for nighttime tower lighting
• Security lighting height limit: 20 feet maximum

Guy Wires and Construction Areas:

• Guy wires require white marking boards (minimum 6 inches wide)

Sign Illumination Requirements

Brightness and Measurement Standards

Signs in Guthrie must adhere to specific illumination requirements that balance visibility with minimal light pollution. These standards are particularly important given the city's historic character.

All illuminated signs must stay within 300 total foot lamberts of luminance. This measurement ensures signs are visible without being excessively bright or distracting.

Digital signs have additional requirements:

• Maximum illumination of 70 foot candles measured from a two-foot distance
• Brightness cannot exceed 500 NITs at night or 6,500 NITs during daylight hours
• Must include automatic brightness adjustment technology that responds to ambient light conditions

Placement and Design Restrictions

The positioning of illuminated signs matters as much as their brightness in Guthrie:

• No illuminated signs within 50 feet of property in a Residential District
• Lighting must be shielded to prevent direct light from shining onto surrounding areas
• Light must be directed upward to avoid affecting roadways or residential areas
• Signs cannot contain flashing, intermittent, revolving, or moving lights

Safety Considerations

Guthrie's regulations explicitly prohibit signs that might create safety hazards:

• No sign can be illuminated to cause glare or impair vision
• Digital signs cannot simulate warning signals or traffic control devices
• Signs must not interfere with driver visibility or create distractions

Lighting in Mobile Home and RV Parks

Streets and driveways within mobile home and recreation vehicle parks require adequate lighting for safety. The regulations specify that these areas must be illuminated according to:

• Current standards of the Illuminating Engineering Society, OR
• One-half candlepower minimum (whichever standard is higher)

Additionally, each mobile home space must have an electrical outlet supplying at least 100 amperes to ensure adequate power for residents.

Tower and Security Lighting Guidelines

Tower Illumination Restrictions

Towers in Guthrie face strict lighting limitations:

• Illumination is prohibited except when specifically required by the Federal Aviation Administration
• Strobes cannot be used for nighttime lighting under any circumstances
• Any required lighting must be directed upward and away from adjoining properties

Ground-Level Security Considerations

Security lighting has its own set of requirements designed to provide safety without creating nuisance:

• Height cannot exceed 20 feet
• Must be focused to avoid conflict with vehicle operators in public right-of-way
• Should be positioned to minimize impact on neighboring properties

Historic District and Landmark Lighting Considerations

Application Requirements

Guthrie takes special care with lighting in its extensive historic district. Applications for changes in these areas must include:

• Detailed drawings of lighting standards to be placed on parcels
• For signs: proposed means of illumination along with materials and design
• For certificates of appropriateness: specifications of light standards and fixtures that would be visible from streets or alleys

These requirements ensure that new lighting installations respect and enhance the historic character of Guthrie's most treasured areas.

Utility Poles and Safety Markings

Pole Placement Requirements

Telephone, telegraph, and electric light poles in Guthrie must be:

• Placed immediately within the sidewalk curb stone
• At corners, positioned within the corner of the circular curb stone

Guy Wire Safety Markings

For public safety, guy wires supporting utility poles must be clearly marked with:

• White boards at least 6 inches wide
• Extending from ground level to 5.5 feet high
• Positioned parallel to the wire and securely fastened
• Maintained in a condition to be readily visible at night

Construction Safety Lighting

Anyone using streets or avenues for building materials must provide warning lights:

• Red lights must be placed at the front and each end of materials/obstructions
• Lights must remain burning during the entire night while obstructions remain

These requirements ensure public safety during construction projects throughout the city.

Compliance Considerations

The city's Electrical Inspector has general supervision over electric light wires and poles to prevent accidents and ensure safety. When installing or modifying lighting:
