I had the opportunity to visit the Jubilee River project last June and was impressed by the conservation and environmental aspects of the design. However, I gained the distinct impression that in some instances these aspects had been given priority over basic engineering design criteria.
I was disturbed, therefore, to read (NCE 13 May) that for the proposed extension of the river, profiling 'is likely to be considered the cheapest option with a benefit to cost ratio of 2:6.
Given the high weighting given to the environment in the existing scheme, I suggest that to minimise costs the Environment Agency should give priority to the engineering design of the extension and accept that other issues should take second place.
