I agree with Tom D. that you really must go with what works.
But, since I have probably worked on more boring, flat, uninteresting sites than Tom, I will comment that there is much more personal preference by the designer in such cases. In essence, a blank canvas to a large degree, although views, sunlight, wind and other factors know no bounds of topography or bordom of terrain.
At Grande Valley in Eloy (
http://www.grandevalleygolf.com/holes.html ) which was done many, many years ago, I had less than 4 feet of fall from one side of the site to the other. We could pretty much do whatever we wanted. I recall laboring over the routing, trying to not be too formula-based, yet wanting to make sure we did not create any undue pace or flow obstacles. My regret there was going with a traditional par total and not looking for five par 3s or perhaps something interesting, such as a par-74! Arizona could use one of those and we certainly had the space!
