The Downtown Commission was formed in 1997 with the adoption of a new Downtown District in the City Zoning Code. The Commission is the approval authority for Downtown Planning, Zoning, Graphics and Design Review issues and is supported by staff of the Planning Division. The Commission functions as the Board of Zoning & Adjustment, Planning Commission and Graphics Commission within the boundaries of the Downtown District. The authority given this Commission allows the zoning approval process to be streamlined by reviewing all issues for a downtown development project simultaneously. The Downtown District, as defined in Title 33 Chapter 3359.03 of the Columbus City Code, is zoned as mixed-use with most land uses permitted through design review. The concept of mixed-use zoning allows the market to determine the location of various land uses if the overall design contributes to the vitality of Downtown.
