Rainwater and heat island management
Heat islands affect both the environment and the health of residents. They reduce air quality by contributing to the dispersion of pollutants and the formation of smog, while affecting water quality and increasing the strength and duration of oppressive heat waves.
This phenomenon, which is increasingly common in our cities, results in temperatures that are 5°C to 10°C above average and a corresponding increase in water and power consumption.
Heat islands stem from reduced vegetation, urban materials and geometry, human activity, and wind-reducing factors such as geographical location.
Increasing the number of bioretention areas by creating rain gardens in the most vulnerable locations—downtown cores, industrial and commercial zones, large parking lots and major traffic routes—is a long-term solution that feeds back into ecosystems while mitigating the impact of nonpoint-source pollution.
Did you know that...
By 2030, New York City will divert storm water runoff on 10% of its impervious surfaces from the sewer system. Permeable paving stones, green roofs, rainwater tanks and barrels, drainage ditches and 6,000 rain gardens will be put in place across the city.
The Pathway to Phytotechnologies and its Rain Garden
The sea of concrete found in the Botanical Garden’s parking lot, the main entrance to the site, will be transformed to make it more consistent with Space for Life’s environmental philosophy and its scientific expertise.
Water retention zones equipped with a green filtration system will make for better rainwater management. Visitors will see how the water collected in the parking lot is being used to irrigate new green spaces. The redesign of the main parking lot will significantly reduce the heat-island effect, which visitors will feel immediately.
The ripple effect of Space for Life’s rain garden concept is already being felt. With the support of the City of Montreal, the project will eventually be extended to the Insectarium and the Pierre Charbonneau Centre parking lots.
