In a world of aslphalt and concrete...not all hardsape is created equal! Water is a PRECIOUS resource. We are fortunate in the Northeast to have an abudnace of fresh water. However, traditional city storm water management systems pipe away storm water instead of allowing it to infiltrate into the aquifers. This Porous Pave system replaced four layers of asphalt driveway at this Rye residence, and now allows for 100% storm water infiltration. (Asphalt is 0% permeable, by contrast).
