Paving over front gardens is damaging to the environment - yet these people are encouraging it!

How very disappointing to read the piece on the news section of PutneySW15 encouraging people to pave their front gardens over to make money, despite the very damaging effect on the environment (http://www.putneysw15.com/default.asp?section=info&link=http://neighbournet.com/server/common/conoffstreetparking001.htm). What's more, this article appears on the very day that judging is taking place in Putney Society's front garden competition! The damage to the environment is caused, as the Royal Horticultural Society points out, by the fact that materials like paving, tarmac and concrete, which are being increasingly used to pave gardens, are less porous than the earth they replace (which can soak up rain). The result is that the amount of rainwater that runs off is increased by as much as 50 per cent, with the additional water usually flowing into street drains which can't always cope, leading to flash floods (https://www.rhs.org.uk/science/pdf/Gardening-matters-Front-Gardens-urban-greening.pdf). The advice being peddled by this Harrison Woods, that “I would encourage homeowners with an empty driveway to register it for renting as soon as possible and see how much money they can make from it. It doesn't cost anything to list a driveway with YourParkingSpace.co.uk, so there's nothing to lose."  No, there's nothing to lose but the damage caused by this idiotic and irresponsible advice, which encourages people to act selfishly, and Woods should be ashamed. And it's all the worse because the "news" piece ends with the mealy-mouthed statement that "there may be a negative effect on the environment".

As yet it is clearly too early for there to be specific data on the effects of the closure of Hammersmith Bridge, but the phenomenon of traffic evaporation is thoroughly established. For example: (1) evidence from over 200 transport professionals and about 150 published documents was collated to provide information on about 100 case studies from across the world. About 60 provided sufficiently detailed evidence for in-depth analytical review. The key findings were as follows. (a) When road space for cars is reallocated, traffic problems are usually far less serious than predicted. (b) Overall traffic levels can reduce by significant amounts. (c) Traffic reduction is partly explained by recognising that people react to a change in road conditions in much more complex ways than has traditionally been assumed in traffic models. ('Disappearing traffic? The story so far,' Cairns, Atkins and Goodman, Municipal Engineer, 2001: https://nacto.org/docs/usdg/disappearing_traffic_cairns.pdf) and (2) A report for the European Commission found that "The experience in a number of European cities is that: • traffic problems following the implementation of a scheme are usually far less serious than predicted; • after an initial period of adjustment, some of the traffic that was previously found in the vicinity of the scheme ‘disappears’ or ‘evaporates’, due to drivers changing their travel behaviour; • as a result the urban environment becomes more liveable in many respects." (Reclaiming city streets for people: Chaos or quality of life? European Commission, ND, http://ec.europa.eu/environment/pubs/pdf/streets_people.pdf) These are only two of the many studies that attest to traffic evaporation against the myth that the level of traffic is always static.
