Lighting Regulations in River Forest, Illinois: Preserving Historic Character Through Thoughtful Illumination

Introduction

River Forest, Illinois, with its rich historical heritage dating back to the mid-19th century, has always balanced preservation with progress. Founded near a steam sawmill established in 1831 and developed significantly with the arrival of the Galena and Chicago Union Railroad in 1848, River Forest grew from a small settlement into an incorporated village by 1880.

Today, this Cook County community of approximately 11,000 residents takes pride in its distinctive residential architecture and commitment to maintaining an ideal living environment. This dedication to preserving community character extends to how the village regulates lighting, particularly concerning signage illumination.

Sign Illumination Standards

General Requirements

River Forest has established clear guidelines for how businesses and properties can illuminate their signage. These regulations help maintain the village's aesthetic character while ensuring safety and preventing light pollution.

The village code specifies that signs may remain illuminated during business hours as long as they don't create a public or private nuisance. This balanced approach respects both business needs and neighborhood tranquility.

All illuminated signs must comply with the village's electrical code requirements, ensuring safety and consistency throughout the community.

Light Intensity and Direction

River Forest places specific limits on sign brightness and light positioning:

• Maximum illumination cannot exceed 120 foot-candles when measured with a standard light meter held perpendicular to the sign face
• Light sources must be located, shielded, and directed to prevent casting glare or direct light upon adjacent property or rights-of-way
• Devices housing light sources cannot protrude more than 12 inches from the sign face or building

Residential Consideration

For businesses adjacent to residential areas, additional limitations apply. Any illuminated sign visible from a residentially zoned area cannot be illuminated between 11 PM and 7 AM unless the business is actually open during those hours, and even then, the sign must not create a public or private nuisance.

This requirement shows River Forest's commitment to protecting residential quality of life while still accommodating legitimate business needs.
