The Environment Agency does not hold the information required to answer this question in a format that could be completed without incurring disproportionate costs.
The Environment Agency is on track to deliver a programme of flood and coastal risk management schemes that over three years is set to exceed the challenging target to provide increased protection to 145,000 households.
The Environment Agency continuously strives to improve its procurement and management of construction and engineering projects. Since 2007 it has completed 102 major flood defence schemes that have protected over 63,000 properties from flooding in England.
Through the Environment Agency's Streamlining project it has been able to reduce the cost of project development, meaning that a greater proportion of the money is actually spent on constructing defences than ever before.
