The idea of blue-green grids is an innovation that holds promise for many cities across Canada, as documented in this recent article from the Toronto Star.
“While Rotterdam’s blue-green grid is still far from completion, it may be seen as a compelling example of how a set of technologies can be harnessed to produce what can be described as a smart city solution to a pressing urban problem.
The technological linchpin in Rotterdam’s strategy has been the installation of a highly sensitive weather radar on the roof of the city’s tallest building. The device is capable of detecting rainfall 16 to 20 kilometres away. Remotely operated blue-green roof control systems can be programmed to dynamically respond to those forecasts and release water that sits in the reservoirs. (A similar project, the Resilience Network of Smart and Innovative Climate-Adaptive Rooftops, or Resilio, is underway at several Amsterdam social housing complexes.)” […]
