BGS 2.0 – BlueGreenStreets 2.0 – implement, evaluate and consolidate
The BlueGreenStreets 2.0 project implements, evaluates and consolidates research results on climate change adaptation in urban spaces. In addition to the establishment of municipal and research-oriented networks and the direct exchange of expertise with associations, planning and engineering offices and municipalities, stormwater tree pits are being further developed as a BGS measure. The BGS toolbox, which is already actively in use, is being tested in practice and then supplemented with new knowledge so that the implementation of blue-green spaces can be realized by a large number of municipalities.
Prospective urban planning: the water sensitive design of cities
Green spaces and open water areas within cities are not only of great importance for quality of life, but also for the microclimate within neighborhoods. In growing cities, because of soil sealing, there is an increasing risk of losing green spaces and simultaneously an increase in the risk of urban flooding. The task of future urban development is therefore not only to develop different land uses side by side, but also to combine them. Urban greenery and urban flood protection need to be integrated into multifunctional streetscapes.
Multicoded strategies for climate change adaptation in urban spaces
In the first funding phase, the group’s research concentrated on multicoded strategies for climate change adaptation in urban areas. Various BGS measures were analyzed using an innovative evaluation system. The results of the first phase of the BlueGreenStreets project were compiled in a comprehensive planning aid for municipalities and planning offices, which promotes the transfer of knowledge and the practical implementation of blue-green infrastructure in the street space. Within the framework of design workshops, exemplary plans with BGS elements could be worked out in various street areas of the pilot cities.
Optimization and application of the BGS-strategy and toolbox in practice
After the successful planning of climate adaptive rebuilding and development of existing urban spaces in the first phase of the project, the developed tools will be applied and optimized in practice in the consolidation phase during BGS 2.0. The pilot cities Lübeck and Potsdam will incorporate the learnings from the BGS toolbox into their current urban development projects to test its practicability. A further focus of the second phase of BGS are stormwater tree pits, for which the aspects of pollutant accumulation, tree vitality and the allocation of tasks and financing during operation and maintenance will be of interest.
To promote resource efficiency in growing neighborhoods, planning tools acquired during the first project phase will be further developed and their prevalence in urban development projects increased. The BGS toolbox is updated and the network of practitioners expanded.
