Hello everyone. I have a question I'm hoping someone can give me some insight on.

I am about to do some site development designs for a client. This particular one of five will be a commercial cluster on 7.5 acres of land. It will have things from restaurants, a bank to a hotel. The site design needs to be a correct representation of what CAN go there, but thats it, pretty much a marketing presentation. My question here is: what is the best way to go about this in Revit. I was thinking of just creating a topography, entering in property lines, table or sketch, and then maybe using sub-regions to separate streets from landscaping, etc. I don't know if I should create building pads, and draw a bunch of building footprints on those pads in the same project, or create separate projects for all of the footprints and link them all to a site project etc. I am hoping someone will provide me with some good info on a good way to get started. Thanks
