The City Planning Office is responsible for shaping the spatial and transportation development of Mainz, the state capital.

Its goal is to further develop Mainz into a livable, sustainable, and future-proof city while balancing the needs of housing, work, mobility, and the environment.

The City Planning Office’s range of responsibilities is very diverse, extending from citywide and subregional urban planning and transportation concepts, plans, and strategies to concrete on-site implementation—such as the design of public squares— the organization of traffic, including signage, and the maintenance of roads and civil engineering structures.
