Here's why removing unused pavement creates a cleaner city

Here's why removing unused pavement creates a cleaner city

Unused pavement is impermeable and prevents storm water from soaking into the natural ground. Instead, the water collects debris, salt and chemicals from the surface of the pavement, then drags those toxins into nearby waterway systems. As a result, urban areas with unused pavement tend to have more pollutants in water runoff than naturalized areas.
