Many thanks for getting back to me so quickly. Could you give me some idea of the likely costs for a barrister to prepare our case? Simply the planning decision was approved on the development site being in Flood Zone 1 as per the current EA flood maps. The flood maps are incorrect and the Council have known this for some time as the correct data for flood modelling was lost when responsibility passed to the Environment Agency some years ago. A group of residents commissioned a report by independent drainage experts using the national modelling and surveying tool which shows the area to be in Flood Zone 2 (as a minimum) which reflects the true picture of flooding in the area over many years and would mean that the drainage solution proposed for the site is in appropriate and that the Sequential test should be applied under the NPPF and the development moved elsewhere. The new flood maps will be ratified by the EA on 4 Sept 2015. The Council chose to ignore this information in making the decision relying wholly on the current flood maps which are incorrect!
A final question - would you be able to prepare our case or recommend someone who could? I will then run this past the group of residents fighting the development.
