Chicago, which claims to have more square miles of alleyway than any other city, is starting to pave them with permeable materials that will reduce run off and cut the heat island effect. They’ll also be installing low energy lighting. The initial costs are greater than just relaying concrete or tarmac but cut the risk of flooded basements and other knock on effects.

Perhaps the scheme could be extended to pavement outside the ally and other pedestrian areas. Far too many of the pavements around here drain off into huge puddles on roads or where there are dips. Take it another step further and let’s have rules that require these materials be used in domestic paving to mitigate all the short sightedconcreting of front lawns that’s become so prevalent.
