    Short description of measure

    Problem to be solved: Urban flooding

    Goal, potential objective: Water retention (can be combined with heat exchange); the stored water can easily be used in times of drought

    Developmental steps: Identification of suitable areas; check governmental regulations

    Instruments, implementation mechanism: Water plan

    Area of implementation: Local, regional

    Responsibilities: Local authority

    Time horizon: Short term

    Economic aspects: Less space needed for retention; possibility for heat exchange with the groundwater; improvement of water quality

    Promoters, obstacles, risks: Pollution of deep groundwater

    Side effects: Stored water can be used in dry periods

    Bridge to mitigation: Less use of fossil fuels due to less heating in winter and less cooling in summer
