Aarhus method for urban planning.

Operational models in planning to learn from

  • According to the wastewater management plan of city of Aarhus, the city applies a two-level model for the management of urban runoff. Municipality Government is responsible for compiling urban catchment level stormwater drainage and detention masterplans (RVDP – Regnvandsdispositionsplaner) whereas each developer in the city is responsible for compiling a separate runoff management plan (RVHP – regnvandshåndteringsplan) in the sub-catchments the development is taking place.

    Planning criteria has been agreed, along with acceptable methods in validating the planned solutions. RVHPs are a compulsory part of each detailed plan and it consists of runoff analysis before and after the planned development, explanatory note for the technical solutions applied as well as foreseen maintenance guidance.

    Both the two-level management plans as well as the modelling capacity allows to identify locations for NBS implementation and plan the adequate performance for the solutions under different conditions.

  • The Stormwater Programme of city of Tampere founds on a comprehensive flood risk assessment of urban catchments paired with a Sponge City analysis that has identified water management related challenges that could be responded with green-blue solutions.

    Also, Tampere has developed a local classification system for stormwater interventions. According to this, NBS are considered as a priority option.

  • The city of Malmö has set up an online planning support tool Technical handbook of Malmö. The technical handbook covers design and planning baselines for different facilities and infrastructures on public land in Malmö. The online format employs cross-referencing between key categories, allowing to integrate green-blue infrastructure guidance to areas like street construction and water management.

    Significant sections in the handbook cover contact information to relevant city officials, planning and design requirements and templates, type drawings as well as more general background information to provide context and justify the relevancy.
