Ickford: Flood Risk

Christopher Pincher Excerpts

Tuesday 23rd November 2021 Commons Chamber

[The Minister for Housing (Christopher Pincher)]

I congratulate my hon. Friend the Member for Buckingham (Greg Smith) on securing this Adjournment debate on a very important topic to all residents of Buckinghamshire but particularly to his constituents. He is a doughty and industrious campaigner on behalf of the people of Buckingham, and tonight, the people of Ickford. I congratulate him on his speech.

I am sure that my hon. Friend will appreciate that because I have a quasi-judicial role as planning Minister, it would not be appropriate for me to discuss in any detail individual planning applications or individual local plans. However, I am concerned to hear from him that the developer in question has not engaged sufficiently with the local community, or with him. I encourage that developer—indeed, all developers—to make sure that they do engage effectively and properly with elected representatives, as well as the communities concerned.

The Government recognise that flooding presents a risk to people and to their homes, villages, towns and cities, as my hon. Friend says. The devastating effects of flooding can be seen every year and the Government take it very seriously. The national planning policy framework is very clear that flood risk assessments are needed for all areas where development is proposed that are at risk of flooding from all sources, both now and in the future. Appropriate design and risk considerations that include allowance for climate change need to be included in any flood risk assessment. Allowances that consider future impacts of climate change on flood risk incorporate a precautionary risk-based approach for more vulnerable areas. This means that increased levels of resilience are—indeed, must be—factored in.

The national planning policy framework sets out a clear, overarching policy on flood risk. It states that inappropriate development in areas at risk of flooding, whether an existing or a potential risk, should be avoided, and alternative locations at lower flood risk should be identified where possible; this is known as the sequential test. Where development is necessary and there are no suitable sites available in areas at less risk of flooding, the proposed development should be made safe without increasing flood risk elsewhere; this is called the exception test. Where these strict tests are not met, new development should not be allowed.

Three national flood zones are identified by the Environment Agency’s flood map for planning. I encourage my hon. Friend to raise his concerns about this matter with the Environment Agency, and specifically about its flood map. Flood zone 3, which is commonly referred to as high risk, is split by a local council into two separate zones, 3a and 3b, where 3b is classified as functional floodplain and has the highest likelihood of flooding. Large parts of many major towns and cities comprise land classified as flood zone 3. Sub-category 3a covers land having a one in 100 or greater annual probability of river flooding, or land having a one in 200 or greater annual probability of sea flooding—possibly not something that my hon. Friend’s constituents in Buckingham are at particular risk of, but I understand his broader concerns.

I must stress that building on land assessed as high risk is not the same as building on functional floodplain. Even then, building in flood zone 3 is not common, as less than 0.2% of land use in flood zone 3 is residential. Flood zone 2 is classed as a medium possibility of flooding, and flood zone 1 is classed as a low probability of flooding and covers land having a less than one in 1,000 annual probability of flooding from rivers or the sea. Areas at the lowest risk of flooding can still experience localised flooding—for example, following a very heavy downpour. That is why we have prioritised the use of sustainable drainage systems for all developments in areas at risk of flooding. The framework is also clear that sustainable drainage should be incorporated in all major developments—commonly schemes of 10 or more homes—unless there is clear evidence that it would be inappropriate.

The framework is also clear that a site-specific flood risk assessment should accompany all proposals in flood zone 1—the lowest risk—that involve sites of 1 hectare or more, land which has been identified by the Environment Agency as having critical drainage problems, land identified in a strategic flood risk assessment as being at increased flood risk in future, or land that may be subject to other sources of flooding, where its development would introduce a more vulnerable use.

Lead local flood authorities must be consulted on surface water drainage considerations in applications for all major new developments. Their comments and advice should inform the local council’s decisions on planning applications and ensure those applications are in line with the NPPF on flood risk. That ensures that local councils have access to appropriate expert advice on the sustainable management of drainage and localised sources of flooding.

For any major developments within flood zones 2 and 3 where the EA raises objections on flood risk grounds, the local council is required to consult the Secretary of State if it is minded to grant planning permission against the agency’s objections. This provides the Secretary of State with an opportunity to call in the decision.

My hon. Friend asked what we have done and called for a major overhaul of the system. I can tell him that we updated the NPPF in July this year to ensure that planning policies support climate change mitigation and adaptation, and that includes tackling flood risk. As part of the update, the framework was amended to require that all sources of flood risk are considered—including includes areas at risk of surface water flooding due to drainage problems—and that future flood risks are taken into account to ensure that any new development is safe for its lifetime, without increasing the risk of flooding elsewhere. The framework is clear that areas at little to no risk of flooding from any source should always be developed in preference to areas at a higher risk of flooding, as I have said.

The framework must be taken into account in the preparation of local plans, and it is a material consideration in planning decisions. My hon. Friend will know that as part of our wider planning reform considerations, we want to put local plan making at the heart of development and ensure that we engage more local people and stakeholders. I assure him that we will be looking at that and the issues he raised as we advance those proposals.

I should also tell my hon. Friend that, as can be seen from the recent update to the NPPF, the Government are not standing still on the issue of flood risk. Last year we published a policy statement setting out the Government’s long-term ambition to create a nation more resilient to future flood and coastal erosion risk. The policy statement outlines five ambitious policies and more than 40 supporting actions, which will accelerate progress to better prepare and better protect our country against flooding and coastal erosion in the face of more frequent extreme weather as a result of climate change. We want to ensure that we are better protected, to reduce the likelihood of flooding and to increase resilience.

This year the Government also published their review of policy development in areas at flood risk, examining key elements of planning policy relating to flood risk and development. It concluded that the Government have robust measures in place to protect people and property from flooding, which all local planning authorities are expected to follow. The review outlines the findings and sets out the actions the Government will take and have already taken, which includes further clarifications of policy.

Mindful of what my hon. Friend has already said, as part of our wider ambitions for an improved planning system we intend to review the NPPF to ensure that it contributes as fully as possible to climate change mitigation and adaptation. I will take careful note of his suggestions in that regard. We are also in the process of reviewing the planning practice guidance section on flood risk to provide further clarification.

We are also investing to improve our country’s resilience to existing flood risk. This year we have made a record investments in flood and coastal defences, doubling the size of the flood and coastal defence programme in England to £5.2 billion, providing around 2,000 new defence systems to better protect a further 336,000 properties. The aim is to reduce national flood risk by up to 11%, helping to avoid £32 billion of wider economic damage and benefiting every region of the country, including his own.

Furthermore, the Government have committed to undertake a review of the case for implementing schedule 3 to the Flood and Water Management Act 2010 concerning sustainable drainage systems. The review will look at the benefits and effects of implementation, as well as alternative methods for ensuring that sustainable drainage systems are incorporated in future developments. It will engage a range of stakeholders, and I encourage my hon. Friend and his friends to be some of them. As well as providing for statutory build standards for sustainable drainage systems on new developments, the schedule would make the right to connect surface water to foul water conditional on local planning approval of the developer’s proposed drainage system. The review commenced in October this year and we expect to publish the outcome in August next year.

I again congratulate my hon. Friend on his persistence in pursuing this very important matter on behalf of his constituents. I hope it is clear to him that the Government take the issue of flooding very seriously and expect it to be an important consideration in the planning system. We also take his views and his concerns very seriously too.

The NPPF is clear that inappropriate development in areas at risk of flooding should be avoided. Where development is necessary, as I say, it should be made safe and resilient, without increasing flood risk elsewhere. National planning policy applies to all sources of flood risk, including surface water, overwhelmed sewers and drainage systems, as well as future risk. We are committed to reducing the risk that flooding poses to our communities. We acknowledge that climate change will increase the risk of flooding, and that is why we have strong protections in place, including the £5.2 billion of investment that I referred to, and we will work hard on our further reforms to ensure that we further protect our communities against flood risk.

I congratulate my hon. Friend on his work on behalf of his constituents in Ickford and elsewhere. I trust that the developer to whom he referred is listening and will engage with him and the communities that are affected at the earliest opportunity. I congratulate him on his debate, and I look forward to working with him in future to ensure that flood risk in all of our communities is effectively mitigated.

Question put and agreed to.
