Pervious Paving
The pervious pavers at Rancho Verde are another first for a Chicago city street. The value of the pervious paver is that it allows stormwater to pass directly through the street surface and into the ground below. Streets are particularly high in pollutants that leach from vehicles, such as oils and gas. The pervious paving allow the water to be naturally filtered by the stone and soil below the street rather than shedding to the sewer system where it has to be chemically treated.
