We welcome the Government’s commitment to act upon our recommendations regarding the cumulative impact on flood risk of smaller developments. While we recognise that national planning policy does refer to cumulative impacts, this has clearly not allayed concerns that these impacts are not given due regard when planning decisions are made. The Government should, as part of its review of planning policy for flood risk, establish to what extent flood risk is increased by the lack of scrutiny given to the cumulative impacts of smaller and permitted development.
