Freiburg is a growing city where more and more people want to live. How can the city continue to be developed in a sustainable way? The Perspectivplan elaborates spatial development options for the City of Freiburg in the next 10 to 15 years. In the course of designing, built-up areas and open spaces are conceived and developed together. Based on a differentiated (GIS)-structure analysis, so far undetected potentials are made visible, development strategies are pointed out and by means of scenarios a future spatial image with a complementary structure plan is generated. The project has been developed in a cooperative process with stakeholders, the municipality, politics and the public.
