Many cities buried urban streams. Here's how to bring them back
As many cities developed, streams that once flowed on the surface were buried underground to make way for growing infrastructure. However, as heavier rainfall, extreme weather and aging infrastructure place growing pressure on cities, these buried streams could become part of the solution.
As cities have developed over time, many surface streams have been buried underground to accommodate growing infrastructure. However, this practice is now being reconsidered due to the increasing challenges posed by heavy rainfall, extreme weather, and aging infrastructure. Stream daylighting, the process of returning streams to the surface, can help manage stormwater, restore habitats, and create more green, walkable public spaces.
While the benefits of stream daylighting are clear, implementing such projects can be complex, requiring feasible sites, coordination across departments, funding, and long-term maintenance planning. This brief will explore two contrasting approaches to stream daylighting, one from Seoul, South Korea, and another from Zürich, Switzerland, highlighting the challenges and benefits of each.
