General Outdoor Lighting Standards

Purpose and Intent

Placerville's lighting regulations aim to balance safety and security needs with preserving the nighttime skyscape. The city seeks to ensure that light trespass and glare have minimal impact on surrounding properties, particularly residential areas.

These regulations don't require lighting an entire property, but rather provide standards for areas where lighting is necessary for public health and safety.

Shielding Requirements

For new multi-family residential and non-residential developments, outdoor lighting fixtures must be constructed with full shielding. This means all light is projected below an imaginary horizontal plane passing through the lowest point of the fixture.

Where light sources are visible beyond the property line, shielding must reduce glare so that neither the light source nor its image from reflective surfaces is directly visible from any point five feet or more beyond the property line.

Light Trespass Prevention

The regulations aim to minimize unwanted light spilling onto neighboring properties:

• Maximum at property line: 0.3 foot-candle (measured vertically at 6 feet height)
• Special considerations: In single-family residential districts, outdoor lighting must be located and/or shielded to prevent nuisance to adjacent dwellings or street rights of way

Energy Efficiency and Hours of Operation

Placerville promotes energy conservation through smart lighting practices:

• Energy efficiency: All new outdoor lighting fixtures must use efficient technologies
• Approved technologies: High-intensity discharge (HID) lamps, including high pressure sodium, low pressure sodium, and metal halide
• Automatic shutoff: Timing devices required to turn off lights between 11:00 PM and 6:00 AM
• Exceptions: Lights may remain on during business operating hours, for security purposes, or to illuminate walkways, roadways, equipment yards, and parking lots

Illumination Levels for Different Areas

General Property Lighting

Placerville has established minimum and maximum illumination levels to ensure safety while preventing excessive lighting:

• Minimum average: 0.5 foot-candles for sidewalks, walkways, and parking areas
• Maximum average: 10 foot-candles for any lighted area
• Uniformity ratio: Maximum 4:1 ratio of average to minimum illumination in parking areas

Public Events and Gatherings

For events after dark, the city requires specific illumination levels:

• Spectator areas: 10 foot-candles
• Stage areas: 100 foot-candles
• Parking and overnight areas: 5 foot-candles
• Restroom and concession areas: 50 foot-candles

Planning director approval of lighting plans is required before permits are issued for public events.

Dance Hall Lighting

Dance venues have a simple but important requirement: "The lighting at any dance held in the city shall be of sufficient intensity so that anybody at the dance is easily recognized."

Sign Illumination Standards

General Requirements

Placerville's sign illumination regulations focus on preventing glare and light pollution while maintaining visibility:

• External illumination: Light fixtures must be fully shielded and designed to focus light only on the sign surface
• Internal illumination: Signs must have opaque backgrounds so only lettering/graphics are visible at night
• Residential areas: Illuminated signs generally not permitted in residential zones unless approved by the planning commission

Historic Considerations

Given Placerville's rich historical character, special attention is paid to historic signage:

• Historic signs: Illumination subject to review and approval by the planning commission
• Architectural harmony: Lighting must complement the historic character of buildings and surroundings

Special Use Lighting Requirements

Sidewalk Dining Areas

For restaurants with outdoor dining, appropriate lighting creates ambiance while ensuring safety:

• Required after dark: Lighting mandatory for evening dining areas
• Architectural compatibility: Fixtures must be decorative and complement building character
• Glare prevention: Building-mounted lights should not cause glare for pedestrians or drivers

Commercial Cannabis Businesses

Cannabis operations have specific security lighting requirements:

• Perimeter lighting: Required for after-hours security (may include motion sensors)
• Official approval: Perimeter security and lighting must be approved by the Police Chief and Director of Development Services

What Property Owners Should Know

Approval Process and Documentation

Before installing or modifying outdoor lighting, property owners should understand the review process:

• Site plan review: Required for new multi-family and non-residential developments
• Photometric study: Must detail number, type, height, and illumination levels of all outdoor fixtures
• Retrofit requirements: Significant property improvements (over $25,000 or 25% of assessed value) may trigger compliance review

Design Considerations

Placerville emphasizes that lighting should enhance, not detract from, property aesthetics:

• Architectural integration: Lighting should be part of the overall architectural concept
• Design harmony: Fixtures and standards must be compatible with building design and adjacent areas
• Restraint: Lighting should be restrained in design, color, and brilliance

Good Neighbor Practices

Even where not specifically regulated, considerate lighting practices benefit the community:

• Direction and shielding: All lighting should be hooded and directed to reflect away from adjoining properties
• Minimize spillover: Consider how your lighting affects neighbors and the night sky
• Preserve historic character: Choose lighting that complements Placerville's historic ambiance
