South Holland IDB
The Board’s Area includes some of the most fertile arable land in the world and is widely recognised as the bread basket of Britain. The area is home to around 60,000 people, a thriving local economy and an increasingly popular tourist destination that attracts visitors from around the country. The area is both locally and nationally important and worth the cost of defending and protecting, now and in future.
Although the entire area is at considerable theoretical risk of river flooding and inundation from the sea, the actual risk is substantially reduced by the work that we do in partnership with the Environment Agency, Anglian Water, Natural England and Local Risk Management Authorities.
The Board’s full watershed catchment area draining to the Drainage District is the same as the Drainage District, which means that we can provide a better service than we might otherwise be able to: this is because we are not compelled to take surface water from outside the Drainage District that we have no control over. This gives us an advantage in being able to protect the people of South Holland and reduce the risk of flooding.
