Flood Risk Assessment Requirements
Where development is accepted as an exception, applicants must submit a Flood Risk Assessment demonstrating identification of all flood sources and adequate mitigation measures.
Where the principle of development is accepted by the planning authority through meeting the 'Exceptions Test', as set out below under the Exceptions heading, the applicant is required to submit a Flood Risk Assessment for all proposals. Planning permission will only be granted if the Flood Risk Assessment demonstrates that: a) All sources of flood risk to and from the proposed development have been identified; and b) There are adequate measures to manage and mitigate any increase in flood risk arising from the development.
