An ordinance was passed to authorize specific building material restrictions and requirements for the River North Urban Design Overlay, covering 165.21 acres across multiple streets. The ordinance mandates that building facades visible from public streets, open spaces, or interstates must use high-quality materials such as masonry, textured metal, precast concrete, or spandrel glass (on upper stories only). The aim is to ensure architectural quality within the overlay district. This ordinance is part of a larger design overlay, BL2024-642.
