Residential & Commercial Property Lighting Standards

Light Trespass Limitations

One of Clear Lake's primary lighting concerns is preventing light from spilling onto neighboring properties. The regulations clearly state:

"Glare or light from any operation and all lighting for parking areas or for the external illumination of buildings or grounds shall be directed or located in a manner such that direct or indirect illumination from the source of light shall not exceed one and one-half (1½) foot-candles at lot lines in any R Zone or C Zone where a residential use is located."

"Glare or light from any operation and all lighting for parking areas or for the external illumination of buildings or grounds shall be directed or located in a manner such that direct or indirect illumination from the source of light shall not exceed one and one-half (1½) foot-candles at lot lines in any R Zone or C Zone where a residential use is located."

This means:

• Maximum illumination at property boundaries is 1.5 foot-candles
• This applies to all forms of exterior lighting
• The restriction specifically protects residential properties

Preventing Nuisance Lighting

Clear Lake's code addresses lighting as a potential disturbance, particularly in residential and ID zones. Properties must not create:

"Any disturbance such as noise, vibration, smoke, dust, odor, heat or glare beyond the confines of the principal or accessory building."

"Any disturbance such as noise, vibration, smoke, dust, odor, heat or glare beyond the confines of the principal or accessory building."

This regulation emphasizes that lighting should be contained within property boundaries and not create uncomfortable glare for neighbors.

Sign Illumination Requirements

Zone-Based Illumination Rules

Clear Lake has established different illumination standards based on zoning:

• ID and Residential Zones: Signs may only be externally illuminated with white light
• Other Zones: Signs may be either internally or externally illuminated
• Special Event Signs: Only external white light illumination is permitted

Technical Specifications

The regulations provide specific technical parameters for sign lighting:

• Exposed Lamps:
• Maximum 11 watts for any exposed lamp
• Inert gas tubes must not draw more than 60 milliamperes
• Diffused Lighting:
• Maximum 25 watts when using inside frosted lamps
• Maximum 25 watts when using exposed lamps with diffusing screens

Visibility Requirements

Sign lighting must be discreet according to this requirement:

"Artificial light sources used to illuminate a sign face shall not be visible from any street right-of-way."

"Artificial light sources used to illuminate a sign face shall not be visible from any street right-of-way."

This means the light source itself should be hidden from view, focusing attention on the sign rather than the illumination.

Public Safety Lighting

Construction & Hazard Lighting

Clear Lake requires appropriate lighting for public safety in construction areas:

"Adequate barricades, fencing and warning lights meeting standards specified by the City shall be so placed as to protect the public from hazard."

"Adequate barricades, fencing and warning lights meeting standards specified by the City shall be so placed as to protect the public from hazard."

While specific standards aren't detailed in the extracts, the city evidently maintains requirements for warning lights to ensure public safety around construction or hazard areas.

Street and Alley Safety

The city code prohibits tampering with safety lighting:

It is unlawful to extinguish any lamp or light erected for guarding unsafe places in streets or alleys without consent.

This reinforces the importance Clear Lake places on maintaining adequate lighting for public safety.

Airport-Related Lighting Regulations

Hazard Prevention

Clear Lake's proximity to an airport necessitates special lighting considerations:

• It is prohibited to "Install, align or use any lighting devices that make it difficult for pilots to distinguish between airport lights and others, create glare in the eyes of pilots, or otherwise impair visibility."

Required Aviation Safety Lighting

Buildings in airport zones may need specific lighting:

• Structures in airport zones must "install all lighting or markings upon said structure as shall be recommended by the FAA"
• These must be "made in a manner consistent with FAA Regulations and Advisories"
• Property owners may need to "permit the City or County, at its own expense, to install, operate, and maintain such lighting and/or markings" to indicate airport obstructions

What Property Owners Should Know

Planning for Compliance

When designing exterior lighting for your Clear Lake property:

• Measure illumination levels at property lines to ensure they don't exceed 1.5 foot-candles
• Direct lights downward to prevent glare issues with neighbors

• Consult with professionals for complex lighting installations

Sign Lighting Considerations

If you're installing illuminated signage:

• Know your zone - residential and ID zones have stricter requirements
