According to
Blog Mickey, the water tower is above Pizzerizos, putting the coaster again,
in one of the concepts, over Mama Melrose and extending into the parking lot and NOT toward ST.
"In this first piece of concept art below, we can see clear identifying marks for the Muppet Courtyard theory. A water tower over Sulley’s shoulder unmistakably matches the current water tower above the PizzeRizzo restaurant, placing the Monsters Inc. building somewhere in the vicinity of the current Mama Melrose restaurant. The shuttered Studio 1 building would be located roughly where the lush park area is currently seen, placing MuppetVision 3D where the corner market is on the right side of the concept below."
