The Town of Westlake has always set itself apart from neighboring communities and it makes no exception to that rule with its Outdoor Lighting regulations. The goal of the Outdoor Lighting Initiative is to:

  • Reduce glare caused by poor lighting
  • Reduce light trespassing onto neighboring properties
  • Reduce light pollution of the night sky
  • Reduce over lighting of an area for the task
  • Reduce waste of energy and resources

Quick Facts

LED Lighting

  • LED lighting is the preferred source for new lighting in the Town
  • LEDs are the most energy efficient lighting and have a longer lasting life than other lighting sources
  • LEDs produce less heat than traditional lighting sources
  • Can be dimmable to reduce brightness

Color Temperature

  • Color temperature is measured in Kelvins (K)
  • The maximum amount of Kelvins for all lighting Town-wide is 3000K
  • Staying below 3000K achieves the following:
    • Reduces light pollution and glare
    • Protects human vision at night
    • Preserves the natural and pastoral aesthetic of the town

Height of Fixtures

Land UseHeight (ft)
Street lighting, right-of-ways, parking areas, nonresidential zoning districts16 feet
Residential zoning districts12 feet
Non-vehicular pedestrian areas8 feet
Fixtures affixed to signalized intersections20 feet

Adaptive Lighting Control

New lighting should aim to achieve one of the below lighting control measures:

  • Automatic Switching System
  • Motion Sensing
  • Dimmable

  •  A site plan of the proposed fixture locations
  • A photometric showing luminous area of each fixture measured in foot-candles
  • The average lighting level of the development
  • The lamp type and height of the fixture
  • The type of illumination
  • The cut-off angles
  • The number of lumens and wattage of each fixture
  • The correlated color temperature of each fixture measured in Kelvins


  • Change in lighting for an existing building, structure, street, parking lots or other outdoor lighting will require an electrical permit.
  • New lighting will reviewed upon submittal of the following:
