An athletic team wants to build a new sports arena

An athletic team wants to build a new sports arena in the middle of the downtown area. The team has bought enough land for the stadium, but needs more land to build an adjacent parking lot. The team asks the city to take the necessary property from the residents and transfer it to the team so they can build the arena. Would it be lawful for the city to do so? If so, how? If not, why not?
