In order to attain a robust and climate-secure society a combination of measures is required. The following methods can be used in physical planning:
- Measures to deal with higher water levels. The municipality may prescribe a recommended height for buildings and land, to prevent construction on low-lying areas. To withstand large bodies of water that cause flooding, the municipality can build dikes. Even ponds and ditches can serve as a buffer against floods and also have the capacity to take care of excess surface water.
- Reduce the risk of flooding by reducing paved surfaces and instead create surfaces permeable to rainfall. In order to handle large flows of water during heavy downpours, space for water passages, so-called integrated flow paths, can be created in urban areas, as well as places to collect excess surface water.
- Identify where in the municipality it is appropriate or not appropriate to construct buildings. The placement of buildings on a site may be important.
- Consider early on that the water and the green structure is an asset in the work to adapt our society. Deciduous trees are effective climate regulators, but also their root system stabilizes and prevents erosion. In addition, they retain large amounts of water during precipitation.
