My girlfriend, who is a landscape architect, has a subscription to Interlocking Concrete Pavement magazine (http://www.icpi.org/node/745 http://www.icpi.org/node/745). On average, I probably spend twice as much time reading it as she does. Most recently, there was an article that described different parking lot geometries designed to prevent rainwater that lands on the parking lot from making it out of the parking lot, carrying lots of toxic crap with it. I also learned recently about horseshoe swales, which collect runoff from things like tennis courts. I've previously read issues of Appliance Design and American Laundry Digest and found similarly interesting stuff. [Edit: In trying to find a diagram of a horseshoe swale, I discovered that there exists a social network for landscape architects: http://land8lounge.com/ http://land8lounge.com/ Looking at the source, I think it's a Ning site branded to look independent (or at least there are a bunch of ning.com assets linked).]
