The increasing impact of climate change leads to complex challenges in adaptation and mitigation for politics, administrations, the economy, and the population. For climate hazards to be considered more carefully in planning processes, they need to be communicated more directly to decisionmakers, especially on the municipal level. Already existing data from environmental modeling, hydrological simulations, and spatial analysis can support the decision-making to develop more resilient cities and landscapes, when they are recognized. A web application was developed on the district level which focused on the transfer of scientific rigor, visualized in maps by engineers and scientists for other experts into a more accessible and suitable medium for non-experts to equip municipal decision-makers with the necessary knowledge.
