Go back in time and include it in the settlement? :) I think it's solidly in the casino's best interest to build it, both for the goodwill and bottom line (I also could imagine they would chip in a little extra to make the design more appealing). I suspect Somerville's mayor is saying all this nonsense mostly to make it clear Somerville won't pay for it. (Honestly, it's a small enough amount that I would rather whatever process is speediest be the one used).
