GardenDesignOnline had an interesting post on Green driveways with a link to an article from the New York Times. The featured architects, Greenmeadow Architects, in the story are right in our neck of the woods.
As for our take on Green Driveways, they are, of course, more maintenance intensive. The technique they show in the article is better than using the traditional turf paver blocks, where the grass tends to die out over time. Newer styles of turf paving block claim to have helped reduce this problem. There are links in the NYT article to manufacturers. Alternatives include permeable pavements such as Polypavement, Decomposed Granite with natural resin binding agents.
