Which is NOT a benefit of permeable pavement?

Permeable pavement is designed to allow water to percolate through the surface, which provides several environmental and functional benefits. One of its primary advantages is the reduction of runoff from precipitation. This is because permeable pavement allows rainwater to infiltrate the ground rather than flow over the surface, thereby reducing the volume of stormwater runoff and mitigating flooding.

Additionally, permeable pavement can improve water quality. As water passes through the porous surface, contaminants like oils, sediments, and other pollutants are filtered out, which promotes cleaner water entering the groundwater systems. This filtration process is another key benefit, as it enhances environmental health by reducing the number of pollutants reaching nearby water bodies.

However, while permeable pavement has many positive attributes, claiming that it demonstrates high durability without maintenance is misleading. Although it can have a longer lifespan compared to some traditional hardscapes when installed properly, it often requires regular upkeep to ensure the pores remain clear of debris and sediment. This maintenance is crucial to the effective performance of the system over time, making durability without maintenance a less accurate statement concerning permeable pavement.
