Hard surfaces, such as driveways, parking lots and buildings interrupt the natural water cycle by preventing rain water from soaking into the ground and creating heat sinks, warming up our cities. By removing pavement and replacing it with native plants, trees and shrubs we are increasing the infiltration rate, recharging our groundwater supply, and cooling our neighbourhoods.
What is Stormwater? Stormwater is the rain or snow that falls on cities and towns and eventually washes into our storm drains. Along the way it picks up a host of toxic chemicals, bacteria, and contaminants. Think about everything you find on the pavement: oil and grease, pet waste, litter, salt in winter. These things all mix with the water that then proceeds to flow through our drains, untreated, back into rivers and lakes. Visit www.raincommunitysolutions.ca to learn more about stormwater.
From Pavement to Paradise
Pavement is an impermeable surface, so all the water that hits it eventually flows off of it, usually into municipal stormwater systems. By removing pavement and creating gardens, polluted run-off is reduced, since gardens are permeable and absorb rainwater as it falls. Eventually this water soaks back into groundwater aquifers, giving us more clean drinking water. Plants also absorb carbon dioxide, and access to green spaces have been proven to be good for mental health.
