93: Clause 52, page 73, line 22, at end insert—
“(6A) Where a strategy area includes a chalk stream, the spatial development strategy must include policies on permissible activities within the area of the stream for the purposes of preventing harm or damage to the stream or its surrounding area.”Member’s explanatory statement
This amendment would ensure spatial development strategies include policies to protect chalk streams.

[Baroness Grender (LD)]

My Lords, Amendment 93, in my name and that of the noble Baroness, Lady Jones of Moulsecoomb, aims to secure the future of England’s chalk streams by enshrining specific protections and standards into our planning regime. As we made clear in Committee, these globally rare ecosystems—there are only 200 in the world—are often referred to as our country’s rainforests in terms of biodiversity and they face genuine risk from piecemeal development and inadequate water management. These are risks that will only intensify without a robust and specific legislative lever.

Relatively recently, I went for a customary walk in a beautiful green space in south-west London, only to discover that the beautiful River Wandle, home to brown trout and kingfishers, had been destroyed by a devastating diesel leak. The Government intend to streamline housebuilding and environmental measures in tandem, but the practical reality is stark.

Chalk streams are uniquely vulnerable. Abstraction of water, chronic pollution and unchecked development have led to tangible declines in many local areas. In 2023, the Liberal Democrats collected data through freedom of information requests, which revealed that one in 10 chalk stream sewage monitors were faulty, with some water companies having much higher rates of broken or uninstalled equipment.

Amendment 93 delivers a targeted solution: a statutory driver for sustainable drainage standards before any development interfaces with public sewers, closing a loophole that currently exists and has allowed cumulative harm to chalk streams. This amendment would ensure that developers are compelled to apply national standards for drainage and water treatment ahead of any permissions, rather than leaving mitigation as an afterthought.

Amendment 94 in the name of the right reverend Prelate the Bishop of Norwich complements this approach, and I thank him for the work he has done on this issue and his environmental expertise, which he has brought to this debate. Amendment 94 tightens oversight and demands full transparency in environmental impact reviews on watercourses at risk, an essential safeguard for communities whose local rivers are too often treated as collateral damage by the planning system’s inertia.

None of us should accept that cleaner, safer waterways are an optional extra and a nice to have. By adopting an amendment on chalk streams and supporting, out of these two amendments, Amendment 94, this House will signal that nature restoration, water quality and sustainable infrastructure are not in competition but can be advanced through co-ordinated and legally binding steps. I urge noble Lords to support these amendments for the sake of our streams and the communities they sustain.

If the right reverend Prelate the Bishop of Norwich moves to a vote, these Benches will support him. It is right that, with something as crucial as our unique chalk streams, we ask our colleagues in the House of Commons to think again and strengthen and protect in law this ecosystem that is almost unique to England. I hope that this House will unite in voting for Amendment 94 and protecting this rare heritage for future generations.

[The Lord Bishop of Norwich]

My Lords, I shall speak to Amendment 94, and I thank the noble Earl, Lord Caithness, the noble Viscount, Lord Trenchard, and the noble Baroness, Lady Willis of Summertown, for their support. I am most grateful to follow the noble Baroness, Lady Grender, who has just spoken so powerfully about her amendment, as well as offering her support for this amendment. Amendment 94 would require a spatial development strategy to list chalk streams in the strategy area, outline measures to protect them from environmental harm and impose responsibility on strategic planning authorities to protect and enhance chalk stream environments.

Chalk streams, as we have heard, are a very special type of river. Some 85% of the world’s chalk streams are in England. They are fed primarily by spring water from the chalk aquifer, not rain, which means that they have clear, cold water and very stable flows. These globally rare habitats are found in a broad sweep from Yorkshire and the Lincolnshire Wolds through Norfolk, the Chilterns, Hampshire and Dorset. The Bure, Glaven, Wensum, Test, Itchen and Meon are river names that come to mind flowing, as they do, through the tapestry of English history and in our literature, such as the River Pang-based Wind in the Willows. They are rich in minerals, especially calcium, and this “base rich” environment supports a distinctive and rich ecology.

It is no wonder that this amendment and a similar one in the other place have received such positive support, including in your Lordships’ Committee. What it seeks to do is such an obvious thing, for what we love, we should desire to protect; what we value, we should safeguard; what is of global significance, we should be deeply proud of.

I am grateful that the Minister responded to my letter to her about my amendment. However, her response was far from reassuring in two ways. First, the Government have pointed to local nature recovery strategies as a way of protecting chalk streams. These could, of course, in future be capable of considering, avoiding and otherwise mitigating for direct damage to these habitats, such as occurs from the footprint of a development near a chalk stream. However, to do so, LNRSs will need more bite in the planning system than they currently have. We are still waiting for the regulations designed to do precisely that, placing a duty on local planning authorities to take account of the nature strategy when making planning decisions. We are still waiting for that to be commenced, and it is now a full two years after these regulations were promised in the Levelling-up and Regeneration Act 2023.

Even once the regulations are passed, LNRSs will not be well placed to map, quantify and avoid or mitigate for the offsite impacts of development such as downstream pollution or the additional water that will be abstracted from chalk streams or their aquifers to serve new homes. These very real threats to our chalk streams, over areas much larger than are covered by strategies, cannot be addressed by LNRSs.

[Baroness Grender (LD)]

My Lords, I thank the Minister. It is very clear there is a strong feeling within this House that there is a need for something to shift and be enshrined in law. I beg leave to withdraw my amendment in order to hand over and support the right reverend Prelate the Bishop of Norwich if he decides to press his.

Amendment 93 withdrawn.

[Baroness Willis of Summertown (CB)]

I want to say a few words in support of another very sensible flooding-related amendment, Amendment 101 tabled by the noble Baroness, Lady McIntosh, to which I was pleased to add my name. I find it alarming that we seem currently to have a situation where some local authorities are using out-of-date maps that do not reflect the current risk of flooding. For example, in a recent report on flood resilience, the Environmental Audit Committee found that:

“Surface water flooding … remains … often underestimated in development decisions”,


and recognised that in spite of surface water flooding being the most common source of flooding in England, it remains “poorly quantified” and “inconsistently planned for”.

We have an opportunity in this Bill to try to address this gap by strengthening requirements on local authorities to ensure that flood risk assessment maps are updated as soon as reasonably practical after the publication of updated Environment Agency flood risk assessments. In Committee, the Minister said that keeping flood risk assessments up up-to-date is “already expected practice”, but with so many properties still being built in areas of high flood risk, perhaps the Minister can assure us about what more can and will be done to ensure that local authorities are updating their flood risk assessments more regularly to reflect the current risks.

[Baroness Grender (LD)]

My Lords, I thank the noble Baroness, Lady McIntosh of Pickering, for yet again raising the flag on flooding—all strength to her— and the noble Baroness, Lady Willis of Summertown, for adding her name. These amendments are clearly designed to address the escalating risks of flooding by embedding precise statutory safeguards into local planning.

Amendment 100 would convert the existing sequential test and the exception test from mere guidance into a legal requirement for local plans. The effect would be direct. Local authorities would be obliged to locate development according to robust risk-based criteria. Our colleague in the House of Commons, Gideon Amos MP, talked in Committee there at some length on this issue and highlighted the dangers where planning permission is still granted for homes on functional flood plains and high-risk areas, often with households left uninsured and exposed to the heartbreak and terrible experience that we discussed a great deal in Committee. Amendment 100 would also mandate the incorporation of sustainable drainage systems, SUDS, except where demonstrably unsuitable. A lack of statutory backing for SUDS, as the APPG on flooded communities has made clear, continues to compromise local flood resilience.

Amendment 101 speaks to the need for reliable current evidence in planning and stipulates that strategic flood risk assessments, SFRAs, must be based on the latest available data from the Environment Agency. On these Benches, the one question we have about it is the level of burden and expectation on local authorities, which already have so many burdens and expectations, but the further burden on households and families of flood risks and living in homes that are built on flood plains without due care is obviously so significant that we cannot ignore it. These amendments establish enforceable statutory standards and require some practical action, and I look forward to hearing the Minister's response.

[Baroness Scott of Bybrook (Con)]

My Lords, Amendments 100 and 101, tabled by my noble friend Lady McIntosh of Pickering, are sensible and pragmatic proposals. As the Minister acknowledged in Committee, the risk of flooding is increasing rapidly, and it is happening now. It is therefore entirely right that our planning framework should embed flood risk prevention and resilience more firmly at every stage, from local plans to individual applications, and I hope the Minister will give these amendments serious consideration and can reassure the House that stronger statutory safeguards against flood risk could still be part of this Bill.
