There have been some recent edits that I wanted to discuss why I reverted.
First, I introduced a commonly accepted definition for the introduction lead by the American Planning Association and the McGill University School of Urban Planning. While there are many definitions out there, I suggest it is the most concise and easy for the average reader to understand. Urban Planning does not necessarily include the licensed (and historically separate) field of architecture. Urban Design can be described as a sub-field that was born of Urban Planning. Additionally, there are many subfields of urban planning including transportation planning, environmental planning, community development, infrastructure planning, natural resources planning etc etc etc. There are many subfields as listed in the Template:Urban Planning. 

The last cluster-f#@$ of an massive article resulted from a lot of competing perspectives of urban planning that led to it being 1. Too long 2. Unreferenced or original research content 3. POV 4. Weasel words 5. Some sections read like a personal essay. So for these reasons I have reverted the changes to the most recent stable version. Lets try to make this more concise and not turn into a crap article again.
