Lighting Regulations in Folly Beach, South Carolina: Protecting Natural Beauty and Sea Turtle Habitat

Introduction

Folly Beach, South Carolina—often called "The Edge of America"—holds a special place in the hearts of residents and visitors alike. From its origins as a densely forested island (the name "Folly" derives from an Old English term meaning "dense foliage") to its evolution as a beloved beach community, this barrier island has maintained its unique character despite significant changes over time.

The city's lighting regulations reflect its commitment to preserving both its laid-back atmosphere and delicate coastal ecosystem. Unlike many municipalities whose lighting codes focus primarily on aesthetics, Folly Beach's regulations are particularly concerned with protecting the endangered loggerhead sea turtles that nest on its shores.

Let's explore the lighting requirements that help maintain this special island's natural beauty and protect its wildlife.

Sea Turtle Protection Lighting

Folly Beach's most distinctive lighting regulations directly support sea turtle conservation. Loggerhead sea turtles nest on the beaches, and hatchlings can become disoriented by artificial light, often crawling toward bright lights instead of toward the ocean.

Beachfront Lighting Restrictions

During nesting season (May 1 to October 31):

• No artificial light may illuminate any area of the beaches
• Floodlights are prohibited near beach areas
• Wall-mounted fixtures must have hoods to prevent beach illumination
• Pole lighting must be shielded to contain light within a specific arc (3-73 degrees) on the seaward side

Dune Crosswalk Requirements

• Only mushroom-type fixtures that direct light downward are permitted
• Fixtures must be installed at least 25 feet apart
• Height limited to not more than one foot above walkover surface
• Illumination limited to 25 watts using "bug" type bulbs

Window Requirements for Ocean-Facing Buildings

• Blackout draperies or shade screens are preferred for windows facing the ocean
• Window tinting, film, or awnings are encouraged
• Interior lights must be configured to avoid beach illumination

Light Direction and Shielding

• Nonresidential lighting: Must be directed downward
