Hi I'm an Undergraduate Planning Student at Sonoma State University. Right now I'm working on a paper regarding the public interest and I was wondering how the "public interest" actually effected the decisions of every day planners.

I've read Michael Brooks and Richard Klosterman's point of view about the public interest and I was just curious how real practicing planners applied the public interest if at all. I understand that it is not easy to define the public interest as well and I was wondering how one would go about creating a definition of the public interest. This seems like a pretty large and important concept so I really want to get a good understanding of the different ideas and concepts about the public interest. Thanks in advance.
