PERMEABLE PAVING

One of the fastest growing approaches to green site development is permeable paving. There are a variety of options of permeable concrete paving but all operate on the same principle: to allow rainwater to seep through a paved surface, which naturally cleanses pollutants and recharges aquifers instead of having the storm water run onto other properties and into storm drains.

Because engineered curb and gutter storm drainage systems are costly to design and build, permeable pavement systems can often reduce overall construction costs. Permeable paving systems typically cost more than conventional pavement, but any additional paving cost is offset, at least in part, because there is less need for storm water management infrastructure. Catch basins, storm water ponds, curbs, gutters and storm drains can be eliminated or downsized. As a result, permeable paving has become a standard part of most developed countries offerings.
