Reduce or prevent light pollution while enhancing the built and natural heritage of Westmount Use these guidelines to ensure the right lighting for you and your neighbourhood:
• direct all light downwards
• use fixtures that have top and side light cut-offs
• light only where and when needed
• avoid using too many lamps
• avoid using high-intensity lamps
• use energy-efficient sources.
Choose light fixtures, bulbs and controls to suit your security needs; use timers, dimmers, sensors and/or photocell controllers to turn off exterior light during daytime or when light is not needed. Guidelines for renovating and building
In Westmount, light that washes across a building's facade is prohibited. Consult the City’s Landscape Design Guideline, section 6.8.2 for more details (available from the Westmount Urban Planning Department or by clicking here
). Lighting in streets and lanes
The City of Westmount is doing its part to reduce light pollution with a project to replace existing Washington street lamps, which send about one-third of their light into the sky, with a different fixture that allows only 2% of its light to shine above the horizon. By reducing light pollution we:
• restore the dark sky so it may be enjoyed again from the city’s lookout and elsewhere
• improve the aesthetic quality of our streets
• sleep better at night and save energy
• reduce disturbances to bird migration
• help protect Westmount’s Summit Woods, a bird sanctuary and part of the Mount Royal Historic and Natural District.
