Permeable concrete and asphalt omit fine particles from their “mix,” creating tiny gaps that water can percolate through. These gaps can become clogged so that rain cannot soak through. Or gas and oil can reach the ground through the gaps. Thus these surfaces are often recommended for areas without heavy traffic. Here, spaces in an auxiliary lot are permeable.

For a parking lot that uses permeable concrete in the most heavily used spaces, see Villa Vasconcellos.
