Protecting Water Quality From Water Runoff
Some researchers have found that increasing the pavement surface area can increase stormwater runoff. A team of researchers at the U.S Environmental Protection Agency conducted a study to determine if increasing the surface area of roadways could successfully reduce stormwater runoff. From the findings of the study, the researchers found that increasing the pavement surface area by even a small amount (1 to 2 per cent) can reduce stormwater runoff by up to 10 per cent. However, other studies have not seen such clear results.
