Question to the Department for Environment, Food and Rural Affairs:

To ask the Secretary of State for Environment, Food and Rural Affairs, what long term risk assessment his Department has made of the (a) likelihood and (b) severity of possible flooding scenarios of the proposed Holocaust Memorial and Learning Centre site in Victoria Tower Gardens over the next 100 year period.

a) Victoria Tower Gardens, the location of the proposed Holocaust Memorial, is located within Flood Zone 3 but is protected by the Thames Tidal flood defences up to a 1 in 1000 (0.1%) chance in any year flood event. However, the Environment Agency’s most recent breach hazard modelling study shows the site to be impacted by flooding if there was to be a breach in the defences or they were to be overtopped.

The applicant has satisfactorily demonstrated that the structural integrity of the wall can be maintained throughout the construction phase of the development and that a continuous monitoring plan will be in place to identify any unacceptable movement within the wall together with contingency actions. The Environment Agency has requested that the requirements of the monitoring plan be secured by way of planning condition.

b) The Environment Agency’s modelling highlights that a breach in the tidal flood defences, while a low probability, could have an impact due to the depth and velocity of the flood water, increasing risk to life. The applicant, in discussion with the Local Authority’s Local Emergency Planning team, should asses the risks of internal flooding, access and exits of the building as part of a Flood Emergency Plan.

The Environment Agency does not assess or approve the adequacy of flood emergency response procedures accompanying development proposals as it does not carry out these roles during a flood.
