To Fortify? That is the question...

Give a couple of bulldozers and some diggers a few days and I am sure they can get the basics done a couple miles a day. No?

I would prefer just chain link and elevated guard towers but that unrealistic on the scale I am looking at.

Why is the chain-link and guard towers unrealistic?

You can put "nests" on top of now no-longer-used power poles in neighborhoods, there's your towers...as to chain link fencing, remember, most good sized urban areas now have almost completely abandoned hardware stores and depending on the area they're likely to have LOTS Of chain-link fencing. Some can be acquired from other places (around school playgrounds, tennis courts, etc.). I think chainlink fencing is more plausible than ramparts, tbh!
