You can get a good idea of property developing from Massland's option course. I would also suggest finding the town plan on the internet, making contact with some town planners, civil contractors and real estate agents so they can give you all the background and financial information you will need to complete a feasibility study.
With the option course, I wouldn't limit yourself to only doing that. Its a good course and a good methodology (I've done it myself), but I personally would also give myself the ability to do things differently as well.
DA's can be very expensive exercises, so be aware of that.
