What Actions Help to Prevent Urban Floods?

In a suburban area, while flooding can occur due to flash floods, coastal floods, or river floods, they are less likely to experience flooding as a result of a heavy rainfall like an urban area can. This is because in addition to storm drains, they have more land masses that can naturally absorb rain - something that is removed for cities.

So how can cities prevent floods?

Infiltration Trenches

Permeable Pavements

Soil Amendments

Flood Walls

Increase green spaces

Since urbanization is known to increase the frequency and volume of floods, it's important for urban planners to evaluate the solutions that help with reducing runoff from urban areas during the planning process. While certain aspects can be added after the city is designed like soil amendments and green spaces, it can become costly to implement other techniques after the city block has been constructed.
