Historical Context and Lighting Philosophy

Preserving Three Forks' Unique Character

Founded in 1911 though with roots tracing back to early 19th century, Three Forks embraces both its historical significance and natural beauty. The city's approach to lighting regulations reflects this commitment to heritage preservation.

Balancing Growth with Tradition

As home to landmarks like the Headwaters Heritage Museum and Missouri River Headwaters State Park, Three Forks' lighting standards aim to support development while maintaining the community's small-town atmosphere and historical integrity.

Safety Lighting Requirements

Construction and Excavation Safety

Safety is a primary concern in Three Forks' lighting regulations, particularly for construction activities:

• Red Lighting Requirement: "Red light must be maintained upon all unfinished work from sundown to sunrise"
• Excavation Safety: Regulations require "hanging red lights about said fence and deposits of materials, from dark to daylight of each day, so as to be plainly seen from every direction of public approach"
• Continuous Protection: "Sufficient barricades must be in place at all times until the work is completed"

Indoor Illumination Standards

For certain premises accessible to patrons, the city requires:

• Minimum Illumination: "Overhead lighting fixtures of sufficient intensity to illuminate every place to which patrons are permitted access at an illumination of not less than five (5.0) foot-candles as measured at the floor level"
• Maintenance Responsibility: "It shall be the duty of the operator, and it shall also be the duty of any agents and employees present in the premises, to ensure that the illumination described above is maintained at all times that any patron is present"

Exterior Lighting Considerations

Parking Area Illumination

The code provides specific guidance for parking area lighting:

• Safety Design: "Lighting used to illuminate a parking area shall be arranged in such a manner that it will not be a hazard to passing motorists or constitute a nuisance of any kind"
• Residential Protection: "Where said parking area is within one hundred fifty feet (150') of any property classified as residential by this title, and where the parking area is directly visible by the residents within one hundred fifty feet (150'), illuminating devices shall be shaded in a manner that would direct the light away from the residential property"

Environmental Impact Mitigation

Three Forks expects developments to minimize negative lighting effects:

• Glare Reduction: "The proposed development should include adequate measures to mitigate adverse environmental effects, including noise and glare, on the site and on surrounding properties"
• Nuisance Prevention: "No use shall be permitted which causes excessive noise, vibration, smoke, odor, dust or other particulate matter, toxic or nontoxic matter, humidity, heat or glare which extends beyond the lot boundaries"
• Definition of Excessive: "'Excessive' is defined for these purposes as a degree that could be observed and agreed upon by the majority of the city council and determined to be offensive or a degree deemed by the state health department to be injurious to the public health, safety, or welfare of the residents of the area"

Flood Protection for Lighting Systems

Elevation Requirements

Given Three Forks' location at the convergence of three rivers, flood protection is essential for electrical systems:

• Equipment Placement: All incoming power service equipment, including "distribution and lighting panels," must be located at least "two feet (2')" above the elevation of the 100-year flood
• Submersible Wiring: All electrical wiring systems installed below the elevation of the 100-year flood shall be suitable for continuous submergence and may not contain fibrous components

Documentation Requirements for Lighting

Planning and Permitting

Three Forks requires detailed documentation of lighting plans:

• Site Development Plans must include "Location and type of all exterior lighting"
• Applications must include "a plan thereof specifying the location of... all overhead lighting fixtures"
• Parking Facility Plans must clearly indicate lighting details
• Planned Unit Developments must have street lights installed to be considered "substantially complete"

Special Use Considerations

The code notes that:

• Permits for chickens don't exempt owners from requirements for lighting permits
• "T Districts" may include specific standards for "Regulation of lighting"
