The Sandwich residence has a long front walk, a blue front door, beige clapboard siding, and a raised section in the middle (possibly a cupola). It may or may not have a garage with white walls.
The Arbelt residence is a tall house with at least one bay window, white clapboard siding, and vermillion roofing. It might be across the street from the Sandwich residence, if the view from Three’s A Crowd and The Calling is anything to go by.
Jeff's house is a yellow clapboard building with a beige front door and wooden fence surrounding the back yard (the raccoons have a crude map of it). Robot meter is situated on the port side. On the opposite side of the street is a beige building with a red porch and a big red garage.
Pete's old house is like an oversized log cabin; completely brown with a small second story. It is about five minutes' walk from Bill's house.
The Wolf residence is that oddly-shaped green one you see pretty much all the time.
The club house is a plain brown rectangular building just down the street from the Wolf residence.
Babylon Gardens itself is very close to Brigham County, with the woods either between or adjascent to the two. It is also less than a day's drive from Kansas.
Here's a map I made using the first panel from Jungle Fever as reference:
As you can see, none of the known locations are recognizeable. Also, it turns out the sign is not the same one from the Easter two-off. Still, it's a start.
EDIT: map now links to slightly bigger map.
Alas Rick is unlikely to give us anything to work with in this regard (because he'd never remember it all if he did 
), but it's always interesting to think about
