A new community building has been added to CityVille in the form of the City Works building. According to a new pop-up you'll receive when logging into the game, the City Works building is essential for your town (although that's questionable, as you'll soon see), and comes with a high population boost to boot.
The building itself can be found under the Community Buildings section of the store for 6,000 coins. You'll need to hammer the frame five times to complete its construction, but rather than collecting items to finish this one off, you'll need to go back to the friend recruitment method, adding a whopping 12 people (in total) to your Crew before the building can be opened. You might be lucky enough to have the Director and Deputy Director's positions filled for you by "Bonus Crew," but otherwise, you'll be able to pay 2 City Cash per position, or send out individual gift requests to those friends that you think would be most likely to accept.
