I haven't updated since December. I have found "The Park" in Dallas over Woodall Rogers Freeway to be a great example concerning the necessary structure. The park is currently under construction. Basic information on the park can be viewed at http://www.theparkdallas.org/. Of all places, the facebook page for the park is a great source of the construction process as photos are updated often http://www.facebook.com/TheParkDallas The park was designed by The Office of James Burnett. I was able to speak with some of the fine folks there. They have helped my to at least understand the basic structure of the park and provided me with a very helpful diagram as well. If you look at some of the construction pictures on the facebook page, you will see a series of reinforced concrete beams running perpendicular to the interstate. All plantings go between the beams, as does runoff. Unless I find a way to get more detailed structural information, I plan on using Woodall Rogers park in Dallas as a guide for what can go onto a deck park. Woodall Rogers Park features pavilions, water features and plenty of sizable trees.
I also spent time reading the Feasability Report for the Hollywood Central Park in Los Angeles. This is another proposed park. The Feasability Report is extensive and has good examples I can use for my site analysis.
