My neighborhood developer allocated very little impervious square footage per lot and therefore the court foundation must not count against my total impervious square footage. Unfortunately, the city of Durham does not recognize pervious concrete as true pervious surface material the way the recognize wood decks, for example. I am going to meet next week with the city of Durham Joint City Planning committee to request a text addendum to the Durham Unified Development Ordinance to recognize pervious concrete as true pervious surface that should not count toward residential impervious total square footage. Anyone have any useful data that could be used as ammo in this argument? I would like to gather studies supporting the efficacy of water drainage through pervious concrete, particularly versus standard concrete. I would also like to know what prececent exists in other cities laws/regulations that recognize pervious concrete the same way they recognize wood decks in terms of it being a true pervious surface. Any help would be hugely appreciated. I would like to use pervious concrete as the foundation for a backyard basketball court in Durham, NC (see snapsports.com).

I would like to know how much does it cost , how does it work in the northern states like Illinois with snow and ice, how long will it last, does it hurt to have clay dirt under the stone base will it still drain as fast, could it be better on roads in the winter for traction and possible us less salt on the streets because it is more porus than ashfault and and concrete ?

Applications for Pervious Concrete Low-volume pavements Residential roads, alleys, and driveways Sidewalks and pathways Parking areas Low water crossings Tennis courts Subbase for conventional concrete pavements Patios Artificial reefs Slope stabilization Well linings Tree grates in sidewalks Foundations / floors for greenhouses, fish hatcheries, aquatic amusement centers, and zoos Hydraulic structures Swimming pool decks Pavement edge drains Groins and seawalls Noise barriers Walls (including load-bearing) I've been told, for an industrial application, that it does not stand up well to truck traffic. That does not mean a residential driveway would be a problem, unless you have very heavy vehicles, such as a camper or motor-home, or can't control the types of vehicles that may drive or park on it.
