Welcome to the Department of Environment and Mobility!

The Department of Environment and Mobility is responsible for the following:

- The City Planning Office, comprising a total of three divisions, is part of the Department of Mobility.
This includes the Transportation Division, which is responsible for traffic planning and for shaping the mobility of tomorrow to be future-proof and attractive for everyone—whether on foot, by bike, by car, or via eco-friendly transportation options. This encompasses projects such as the development of the SUMP, a mobility plan for Mainz. The Traffic Engineering Division oversees, among other things, traffic signal systems, the compilation of traffic data, the parking guidance system, and parking meters. The
Road Operations Division is responsible for the maintenance of city streets as well as civil engineering projects. They monitor the road infrastructure of the state capital, Mainz, on behalf of all residents to ensure it remains in proper, functional, and safe condition. This also includes civil engineering structures (such as bridges).
The Road Traffic Authority is responsible for road closures of any kind within the traffic area and is tasked with ensuring traffic flows safely. Construction site management accounts for a large part of the planning and coordination. This department handles the issuance of resident parking permits, parking accommodations for people with severe disabilities, bollards, markings, and signs.

- The Parks and Environment Office, which covers environmental planning, nature and species conservation, and landscape management, emission control, environmental information, climate protection and climate adaptation, as well as energy consulting, open-space and property planning, environmental regulations, park maintenance, and tree care, along with technical services—including the fountain maintenance crew and playground inspections—and responsibility for the Mainz Wildlife Park.
- The City Cleaning Department (Office 70), responsible for street cleaning
- The Municipal Waste Management Authority of Mainz and Mainz-Bingen (public-law institution), responsible for waste disposal
- The Wirtschaftsbetrieb Mainz (public-law institution), responsible for drainage and cemetery services.

The areas of responsibility of the Department of Environment and Mobility thus span key areas such as environmental protection and species conservation, air quality protection, climate protection and climate adaptation, open space design and green space maintenance, all the way to traffic planning, maintenance and redesign of streets and public squares, as well as street cleaning, waste disposal, drainage, and cemetery services.

The Department of Environment and Mobility also handles cross-cutting issues; examples include the Aircraft Noise Commission, participation in the AGFFK, and cooperation with the MVG.
