What is one of the main benefits of using permeable pavers in landscaping?

1. Reduces flooding

2. Increases soil acidity

3. Decreases plant growth

4. Requires more maintenance

The correct answer is: Reduces flooding

Using permeable pavers in landscaping primarily aids in reducing flooding. These pavers allow water to seep through the surface, facilitating natural drainage and groundwater recharge. This is particularly beneficial in areas prone to heavy rainfall or urban settings where impervious surfaces can lead to excess runoff. By promoting better water infiltration, permeable pavers help to manage stormwater more effectively, reducing the likelihood of flooding and mitigating issues such as erosion and the overflow of drainage systems. In contrast, some options like increasing soil acidity or decreasing plant growth are not associated with permeable pavers, as these materials generally support healthier plant environments by allowing for better water infiltration and air exchange. Similarly, while maintenance is necessary, permeable pavers are often designed to be low-maintenance compared to traditional hardscaping options that can require more upkeep related to drainage problems or sediment buildup.
