FOLLOWING the building of the flood defences at the Hemingford Road roundabout near St Ives I am left a little bemused. The defensive hump in the road, outside the premises of Vindis Motors, has been canted such that on one side of the road it is about three quarters of a metre lower than the bank that runs away from it. On the opposite side of the road it appears roughly level. This leads me to think that either the road is too low at this point, and will possibly allow water to flood over the top at high levels or, more worryingly from a financial viewpoint, the whole of the rest of the bank is too high, or higher than it needs to be. I would be interested to know if this has been spotted by others, and whether anyone knows the reason for this apparent anomaly. RICHARD WILLIS, Station Road, Warboys Editor's note: The Environment Agency says that although the flood defences look high, this has been done to allow for long term settlement and damage while still maintaining the same level of defence.
