February 2012: Pourous Pavemnet

_ How do landscape architects store storm water on-site? One way is to employ porous or pervious pavements of which there are many varieties. Porous asphalt paving is a special mix of asphalt designed with aggregate sizes and binders that allow water to infiltrate into the soil layers below as opposed to being directed and piped to subsurface drainage systems. Wondering what it all looks like? On a recent cold and wet day, I  took a trip to Walden Pond Reservation in Concord, Massachusetts to see for myself. Here you will see an installation of porous asphalt that has been in place since 1977!
