What is one key benefit of using permeable pavement?

One key benefit of using permeable pavement is that it reduces runoff and improves water quality. Permeable pavement allows water to infiltrate through its surface and into the underlying layers, which helps to manage stormwater runoff at its source. This infiltration reduces the volume of water that would typically flow over the pavement and into storm drains, which can alleviate flooding and minimize erosion.

Moreover, as water percolates through the pavement, it undergoes natural filtration, which can remove pollutants and sediment. This process ultimately contributes to cleaner water entering local waterways, thus enhancing the overall quality of the water.

The other choices present concepts that do not align with the primary advantages of permeable pavement. Conventional drainage systems would not be as necessary with permeable options, as they are designed to manage water on-site. While maintenance is indeed required for permeable surfaces to remain effective, it is not accurate to claim that they require no maintenance. Lastly, while aesthetic appeal can be a factor, it is not a primary functional benefit compared to the environmental advantages offered by permeable pavement.
