Which of the following is a characteristic of a porous pavement?

A characteristic of porous pavement is that it allows for water drainage to the ground. This unique feature is designed to manage stormwater runoff by enabling water to pass through the surface and seep into the underlying soil layers. This permeability helps reduce surface water accumulation, decreases the risk of flooding, and promotes groundwater recharge.

The materials used in porous pavement are typically engineered to create voids or spaces that facilitate this drainage, preventing water from pooling on the surface. This approach not only aids in managing stormwater but also contributes to reducing heat island effects in urban areas by allowing natural processes to occur.

In contrast, the other options describe characteristics that are contrary to the purpose of porous pavement. For example, completely waterproof materials would inhibit drainage, and solid concrete only materials would not provide the necessary porosity for water infiltration. Therefore, option B accurately captures the essence of what porous pavement is designed to achieve.
