This is the location it would be built.

many years ago they also floated the idea of building a Super Wall Mart in this location.
Nearly all of Maple Ridge's current development is in the eastern half of the municipality, and people have been pushing for shopping centres east of the town centre for a long time.
I personally think it should be reserved as farmland, but if I had to choose between Walmart and Ikea, I would choose Ikea, i think it will bring in more people from out of town than a Walmart.
Ironically this location is very close to the now discontinued ferries, so coming from other areas south of the river to this location is arguably more difficult now than before the opening of the bridge.
