The reason why Walmart is committed to a store that is part of a mixed use project at 1st and New Jersey Avenue NW in Washington DC
Because elsewhere in the building, the company will be housing its Washington, DC-based lobbying operation.
They want to show that they are "urban." Even though only 2 of the 6 DC Walmarts will be in vertical mixed use projects.
Because "seeing is believing," Walmart will have the upper hand with elected officials vis-a-vis local communities, when the company says it is committed to fitting in to urban locations.
