Flood Plains: Housing Development

Baroness Bakewell of Hardington Mandeville Excerpts

Thursday 24th June 2021 Grand Committee

[Baroness Bakewell of Hardington Mandeville (LD)]

My Lords, it is a pleasure to follow the noble Baroness, Lady Ritchie, and I am grateful to the noble Baroness, Lady McIntosh, for giving us the opportunity yet again to raise our concerns about concreting over natural flood plains. I declare my interest as a vice-president of the LGA. I am currently working on the Environment Bill, where both water management and recycling are high on the agenda. My speech is largely recycled from previous contributions.

The truth is that your Lordships continue to make very valid and cogent points about the dangers of building on flood plains, but the Government continue to ignore this. Many years ago, a developer put in an application on the Somerset levels. This was rejected by the local district council, but the developer appealed. The then Secretary of State overruled the district council and allowed the development. This was before the catastrophic floods of 2014, when the Somerset levels were on every TV news bulletin.

Ministers and opposition spokespeople visited in their droves and royalty came, complete with wellies—although, to be honest, they really needed waders. They came to look at the plight of those whose homes had been flooded—a miserable experience. Some of those flooded were in new houses, some in homes which had been there for a considerable time. The ancient village of Muchelney was completely cut off and could be accessed only by boat. It took several months for the water to completely recede and some sort of normality to return.

There are an estimated 5.2 million properties in England at risk of flooding. The Environment Agency says that if the current rate of planning applications on functional flood plains continues, this could double in 50 years. The Somerset Levels are not the only area in the country prone to repeated flooding, as we have heard. The Environment Agency website has detailed maps of where functional flood plains are, so this is not a mystery to planning authorities.

On the district council where I was a councillor, all planning applications had spaces for the Environment Agency, highway authority, et cetera, to make comments on the application. Often they left them blank or merely had no concerns. All statutory bodies are extremely busy, and the Environment Agency in particular has to respond to emergencies on a regular basis, especially now that climate change has radically altered our weather patterns. It has not helped that Defra, in its wisdom, has cut the Environment Agency budget. I believe it is time for the Government to make it a legal requirement for the Environment Agency to respond to all planning applications of more than five homes, where they are likely to be situated on a functional flood plain.

It would, of course, be helpful if local authorities were given the power to refuse all applications on flood plains, regardless of their merits, unless significant flood prevention schemes were part of the application. Developers believe that a likely occurrence of once in 200 years means they can ignore guidance. There are many communities in which a “once in 200 years occurrence” has happened twice in the last 20 years.

The Somerset Levels are very definitely functional flood plains. When severe rain is predicted, there is a plan for which sluice gates will be opened, in what order and when. Sometimes the whole area is flooded if the rain is persistent over a long period of time. The whole object of flooding the plains is to keep a safe level of water in the River Parrett and prevent the town of Bridgwater flooding. That objective has been fulfilled for many years, but for how much longer if more homes are erected? Perhaps those homes will be erected on platforms via stilts and residents will buy boats instead of cars to keep in the spaces under their homes.

The Government’s proposed planning Bill has come in for considerable criticism; I have a premonition that at some stage I will be speaking during its passage. It is time that the Government had an overall strategy on how they are going to manage water, safely store it during winter for use during the summer droughts and deliver the number of homes needed without building anywhere near flood plains. Can the Minister confirm whether there is such a strategy? This must be a strategy that local people with knowledge can contribute to and not one that is cobbled together from on high.

The noble Baroness, Lady McIntosh, and others have raised very significant issues. I hope the Minister is listening. It is unacceptable for London’s city-dwelling civil servants to produce policies which have devastating effects on rural areas. I am sure he is aware of this and will be taking note of our comments.
