Add another £1bn to the Olympics budget, Gordon
I'm willing to lay a tenner that by the end of next week some enterprising consultant will point out that
1) The 2012 Olympic site is on one of London's highest flood-risk areas (see map)
2) Olympic development will reduce natural drainage and ground absorbency
3) Existing drainage is completely inadequate and new drainage planned for the Olympic site will simply overwhelm current capacity.
The IOC will then seek assurances from the 2012 developers that drainage will be adequate, and the site will be protected against flooding. Of course, it will turn out not to be proof against rain such as last week's ....
