Under the name “Am Zoll Lörrach Riehen”, a new, model district between Germany and Switzerland is being created as part of the IBA Basel. The planning process? Complex. As a project area on an external EU border, those responsible for the project have to deal with overarching dependencies, different planning systems and land conditions. We spoke to Monika Neuhöfer-Avdić, Mayor of Lörrach, and Ivo Berweger, Head of the Construction, Mobility and Environment Department at the Riehen municipal administration, about the challenges of the project.
Nobody in the Basel region is likely to forget March 16, 2020 any time soon. Where around 35,000 cross-border commuters usually pass through customs every day, border traffic came to a standstill on that Monday. This was also the case at Lörrach Riehen customs, an IBA Basel project site. A new model district is being built here as part of the International Building Exhibition – between the municipalities of Lörrach (D) and Riehen (CH). With this, the responsible municipalities want to create new everyday places for the population of the Zollquartier on both sides of the border and, by upgrading Basler Strasse and connecting the two important tri-national recreational areas of Tüllinger Berg and Maienbühl, create high-quality open spaces and a new quality of life. In addition, the planned concept for Basler Strasse will enable the later introduction of a streetcar and the expansion of the Lörrach-Stetten train station into a binational mobility hub.
The planning process for this is complex. The project area is located on an external EU border and is therefore subject to different planning systems and land conditions. The large number of stakeholders involved and the different interests involved make the project a challenge. In addition, the project is part of the “National Urban Development Projects” funding program of the Federal Ministry of the Interior, Building and Community (BMI). The ambitions in terms of design and process quality are correspondingly high. All in all, it is clear that this is no easy task. However, good cooperation has been established between the two municipalities in the course of the IBA Basel in recent years, which has spurred on integrated project development. We spoke to the responsible project sponsors Monika Neuhöfer-Avdić, Mayor of Lörrach, and Ivo Berweger, Head of the Construction, Mobility and Environment Department in the Riehen municipal administration, about their collaboration and future challenges.
“The joint IBA project at customs has led to closer cooperation across the common border.”
Monika Neuhöfer-Avdić, Ivo Berweger: IBA Basel has been actively promoting cross-border cooperation for more than ten years. Has IBA Basel brought your two municipalities closer together?
Monika Neuhöfer-Avdić: Quite clearly, yes. The fact is that since the start of IBA Basel 2020, around ten years ago, the region has become more closely interlinked both politically and, above all, professionally. We have gotten to know each other and our needs, perspectives and systems even better through the IBA. Knowing each other is the basis for trusting each other and it is precisely this trust that is the basic prerequisite for good cooperation. We now accompany the cross-border planning processes side by side as a matter of course. It is precisely this naturalness that makes our special region so special. The IBA has a great deal to thank for this.
The IBA Basel is an IBA of processes. Have you changed the processes in your administrations in recent years? Is there any evidence of a transformation?
Monika Neuhöfer-Avdić: We have not changed our own processes. But we have expanded our processes and, above all, our thinking to include the constant participation of colleagues from the other municipalities involved in the project, which, as in the case of Lörrach and Riehen, are separated not only by a national border but also by an external EU border. For German municipalities, the concept of “municipal planning sovereignty” is fundamental. However, the fact that we are no longer restricting our say to our own municipal planning area, but are also including the neighboring municipalities, is the biggest transformation we have experienced. In technical terms, this is exactly the right approach. Because if you look at Lörrach and Riehen together, you get the picture of a single city that also includes Basel. And we should also plan this Lörrach-Riehen-Basel city together.
Ivo Berweger: The joint IBA project at Zoll has led to closer cooperation across the common border. In my opinion, this in turn led to a greater understanding of the different planning decision-making processes, which are different after all. In Switzerland, planning decisions are subject to referendum and then quickly have to pass a popular vote.
In your opinion, did the IBA Basel fail because of something?
Ivo Berweger: Compared to other IBAs, the IBA Basel was very challenging because three countries with sometimes very different planning cultures and planning law systems had to be brought together. This initial situation made the project processes more complex and demanding in some cases. The customs project was a good example of this: for example, customs authorities from Germany and customs authorities from Switzerland had to be involved, as did Deutsche Bahn AG and SBB; and of course the planning representatives and political representatives from Lörrach and Riehen, as well as representatives of the IB and the Basel agglomeration program, the district of Lörrach and the canton of Basel-Stadt. This resulted in a large number of stakeholders on both sides of the border who had to be involved.
“And that’s exactly what I dream of when I think of the Zollquartier.“
If you were to start the IBA again today, what would you do differently?
Monika Neuhöfer-Avdić: If I were allowed to start again, I would make sure that such a process becomes visible to all those involved and, above all, to the local population at a very early stage through small project realizations and that added value is created quickly. Positive project resonance also creates positive process resonance, which is important when you are going through a planning marathon like we are.
Ivo Berweger: That’s a difficult question. I think there are almost too many cross-border committees in the Basel area, which means that there are many additional interfaces. It was perhaps not easy for the IBA to bring a new impetus to cross-border planning. In my opinion, we should try to bundle these forces better in the future.
What is your vision for the “Am Zoll Lörrach/Riehen” project?
Monika Neuhöfer-Avdić: The IBA Zollquartier project is a wonderful task for the future. By this I mean a task that will be faced everywhere in the future, namely: creating living space from the “traffic space” resource available everywhere. Our competition process from last winter has now produced the first images, all of which show a bright future for this district. And that’s exactly what I dream of when I think of the Zollquartier. Another dream is that other local authorities will follow our example and exploit these treasures of space. Then we’ll have achieved the kind of radiance with this project that is also important for an IBA project.
Ivo Berweger: I hope that the development potential on both sides of the border can be realized on the basis of the images in such a way that buildings and districts are created that offer a good quality of life for the population and that the border is irrelevant to them.
“Everyone must and will need to work together to make the shared living space a success.”
What challenges do you face during implementation?
Monika Neuhöfer-Avdić: On the German side, we will have to struggle with being allowed to redesign a space that appears to be fully built. By this I mean the provision of the necessary resources, especially personnel, by politicians. Unfortunately, public spaces are the ones that we as planners have to defend the most when the belt is tightened. Yet these are the future places of our society, places where people can meet in a society whose main disease of the future will be loneliness.
Ivo Berweger: On the Riehen side, the development of the adjacent 17-hectare Stettenfeld is a challenge. In the recent past, the development of previously underutilized areas has always been controversial among the people of Riehen.
What will happen to the project after the IBA? What challenges does the region have to face with its completion?
Monika Neuhöfer-Avdić: In everyday life, we are an extremely networked region. Think of the many commuters, whether in the work, residential or commercial sector. On the other hand, not everyone in the region realizes how much cooperation is and will be required for the success of our shared living space. Unfortunately, we are also noticing an increase in parochial thinking in our region. On the other hand, this is also an incentive to keep working together. Because one thing is clear: together we can shape our future even better. And the IBA is far more than the sum of its projects.
Ivo Berweger: Shaping the future together is also natural and important from my point of view, because the border is becoming less and less perceptible in spatial terms. For me, the most important shared infrastructure is the Regio S-Bahn, the expansion of which is unfortunately only making very slow progress due to the border location with three countries, three railroad companies involved and three legal systems. For me, the further expansion of the Regio-S-Bahn would be a high priority for the Basel agglomeration.
