Permeable-DrivewayJune 13, 2009–Today’s Way: As we all know, the concrete jungle creates many problems for our environment, and all those paved parking lots, streets, highways and driveways are some of the star offenders.   One major issue with all of that pavement is, when it rains, rain water is diverted into gutters and mixing into sewage systems.   When it rains a lot, all of that extra water overwhelms arcane municipal water management systems which then dump raw sewage and rain water into overflows, also known as the nearest lake, river or ocean — totally untreated.  Another problem is that these ribbons of black asphalt criss-crossing our great lands tend to absorb energy from the sun during the day, gathering up thermal mass, then slowly releasing the heat when the sun sets and raising environmental temperatures in the form of global warming.  Other side effects of our love affair with asphalt is the constant leaching of toxic chemicals into the areas along roadways, including wetlands and vast agricultural landscapes which happen to be located nearby.

Permeable Driveways/Parking Areas are one excellent way to provide clean, beautiful and low maintenance parking and driving surfaces while allowing all of that rain water to naturally trickle down through the ground and back into the water table, where it belongs.  Permeable surfaces come in a dizzying array of options, but the most basic are porous paver bricks which fit together with patterned open holes, which are set into and filled in with pea gravel (as in the photo, above right).  This attractive solution keeps your car protected from mud and dirt, keeps vegetation at bay and at the same time, because of the many lighter color options, does not have to absorb and release heat energy in the same way as asphalt.  Permeable driving surfaces are a beautiful solution for businesses, cities, developers and individuals committed to a greener future.
