St. Louis Centre is finally such a distant memory that St. Louis officials have given the structure a new name, Seventh Street Garage (and retail).  The once-popular (for about a year) downtown mall, will become three floors (750 spaces) of parking for US Bank Building and One City Centre, a two-floored movie theater, and 70K of first floor retail – owned by the Missouri Development Finance Board.  Clayco and Environmental Operations will partner as the developers of the $31 million project.  The columnist plans to arm-wrestle the St. Louis Business Journals’ savvy Lisa Brown and the Post-Dispatch’s able duo of business reporters named Tim for the details of the new retail users.
