The Special Urban Development Projects department manages and develops large-scale urban development measures and strategically important individual projects for sustainable urban development.

These include the impulse areas from the Integrated Urban Development Concept Wiesbaden 2030+ as large-scale focal points for settlement development, as well as conversion areas for internal development. Together with the urban development and urban planning departments of the urban planning office and other specialist departments, the "experimental spaces for sustainable urban development" are also being jointly developed.
