Lighting Regulations in Riverside, Illinois: Preserving Historic Character While Maintaining Modern Standards

Introduction

Nestled along the Des Plaines River, Riverside, Illinois stands as a testament to visionary urban planning. As one of the first planned communities in the United States, designed in 1869 by renowned landscape architect Frederick Law Olmsted (of Central Park fame), Riverside boasts a distinct aesthetic that merges natural beauty with thoughtful design. The village's curving streets, abundant green spaces, and picturesque setting have earned it National Historic Landmark status.

This rich historical legacy is reflected in Riverside's approach to lighting regulations. The village's distinctive 19th-century gas lamps aren't just decorative elements—they're integral to the community's character and inform modern lighting standards throughout the municipality.

Riverside's Historic Lighting System

The Ornamental Street Lighting Standard

Riverside takes great pride in its historic lighting infrastructure. The village code specifically mandates preservation of its ornamental street lighting system, consisting of cast iron posts with globe and dome fixtures. These are the only permissible street lighting standards allowed for commercial and residential streets and public park areas within the village.

Preservation Efforts

The village board maintains a current inventory of the street lighting system and keeps replacement ornamental standards and parts on hand to quickly address any damage or loss. This commitment ensures the consistent aesthetic that helps define Riverside's unique character.

Historic Gas Lighting Legacy

The original plan for Riverside included ornamental gas streetlights along the road system. This historical element is preserved not only through physical fixtures but also in the regulations that govern modern lighting throughout the community.

Swimming Pool Lighting

If you have a swimming pool on your property, artificial lighting must be:

• Arranged and shielded to direct light away from adjoining properties
• Carefully positioned to minimize impact on neighbors
