Infrastructure

Electrical capacity needs to triple- West of cambourne. reliance on Little Barford power station which is a gas turbine power station. This has a significant impact on plans for new development within this area.

National infrastructure policy will overshadow local policy.

Current proposals for an extended bus network by the greater Cambridgeshire mayor need to be abandoned. With the projected growth to the area you propose we need radical, transformative sustainable travel alternatives that persuade people to switch from their car to either active travel or mass public transit. Buses and guided busways will not achieve this. People view buses as uncomfortable, dirty, low class options. Cambridge is the flattest city in the UK and ideal for rapid mass transit like trams or light rail. Such a network would be efficient, reliable, desirable & implementable on major arteries into Cambridge

General comment
Green Belt, City Conservation Areas and all main Historic Approach roads like Madingley Road, Barton road must be protected with principles of enhance and protect in transport strategy. Not destroy roads with bus lanes, lights, gantries and new roundabouts where the car or bus dominates.
The reasons for congestion are historical geography. There is simply not enough public bridges with capacity for cyclists, pedestrians let alone buses or cars, to cross the river Cam, in a medieval City with College privatised land.
There is only one viable solution. Tunnels under City with Cambridge Connect scheme phased in.

Huntingdonshire District Council has no comment on this matter.

The Stapleford site is being promoted on ‘good transport links’ with one train per hour from the Great Shelford Station! The village is within a ten minute cycle distance from all the local Campus sites. The connectivity problems arise from the A1307 (which connects these sites) and the lack of rail route from Haverhill where many employees live due to the affordable housing there. Reopening the Haverhill train line would remove much of the traffic from the A1307 and alleviate the traffic problems we have through the village

Infrastructure policies

4.61. Significant infrastructure is being brought forwards in the Greater Cambridge area, including EWR. Additional Park and Ride provision is also planned, together with the C2C. MGH supports the proposed policy direction, including Policy I/ST which seeks to deliver sustainable and inclusive communities by minimising the need to travel and reducing travel distances. We agree that new development should be located appropriately to maximise the benefits of investment in this new strategic infrastructure, which has the ability to increase the availability and use of more sustainable modes of transport and thereby address the environment and on quality of life impacts of car use.
4.62. Local infrastructure such as schools, health facilities and leisure facilities should be key elements of new development if it is to be sustainable and contribute to the creation of robust, mixed-use communities. Such infrastructure is best delivered where its effectiveness is maximised across both existing and new communities.
4.63. The MGH proposals at North Cambourne would deliver new infrastructure that serves the new community, but also serves the existing community at Cambourne. New residents would benefit from the existing services and facilities provided at Cambourne, with new infrastructure broadening choices. The extension of Cambourne will deliver new options for education, additional community facilities with opportunities for cultural facilities, and a broader leisure offer that could include for example a swimming pool or local cinema. Smaller developments, for example in many of the surrounding villages, are not able to deliver such opportunities because neither the existing community or the new development provide sufficient critical mass to support them.
4.64. Utilities will need to be carefully considered alongside new development proposals. As the move to electric cars takes place, the burden on the electricity grid (for vehicle charging) becomes much greater. New developments will need to consider new ways of generating electricity to enhance and supplement grid supply. Options to generate renewable energy on site will be fully investigated to maximise the output potential in a compatible manner with the proposed masterplan. This is currently likely to include rooftop photovoltaic panels, but other sources of energy, such as heat sharing, may become apparent as the masterplan is developed. Such an investment in new infrastructure can best be achieved on larger, mixed use developments that allow heat to be used efficiently by transfer from employment buildings, which need heat during the day, and homes that require maximum heating during the evenings.
4.65. Delivery of the Local Plan, and its ability to be found sound, is contingent on water supply being adequate without causing f environmental harm, including excessive demand on the chalk aquifer. A number of measures are being explored – including water transfers and imports. However, current evidence says that the planned reservoirs and improvements to supply will be too late in the plan period to meet the need of the preferred trajectory.
4.66. An ‘Integrated Water Management Study’ is part of the evidence base, with inputs from Stantec. At the Regional level we understand that the water companies are looking at the co-creation of a regional plan – that will be the subject of consultation next year (albeit the final document may not be available for the GCP Examination in Public).
4.67. We note that, on water supply and wastewater treatment, the Stantec supplementary paper states that specific constraints which require management and/or further investment associated with the preferred spatial option (Option 9) are connected to growth at Cambourne. At Cambourne there are local wastewater treatment capacity constraints although opportunities to supply Cambourne with fresh water from outside the area easing likely short term local supply shortages.
4.68. Usage in Cambridge Water Area is also notably high (143 litres per person per day) compared to standard national requirement for new homes – so the area is at risk of serious water stress without significant measures to improve supply. The proposed approach to reduce / re-use would be a move towards 80 litres per person per day, which the Councils say doesn’t add much more to the cost of development according to the LPA. The scheme will aim to target this lower value with a combination of low flow fittings, and potentially rainwater harvesting systems, either on an individual building level or as a centralised system, incorporated within the development SuDS strategy.

Horningsea Parish Council does not believe that the proposal to relocate the Cambridge Waste Water Treatment Plant - a fully functioning wastewater treatment plant - to Green Belt is a good use of £227 million of taxpayers’ money. The infrastructure to treat the sewage is already in place and has capacity until 2050. The proposed relocation (that is a mere 1.5km away) will build a new site that has capacity until 2050. This is a waste of money.

USS notes the ambitions of the infrastructure policies to deliver transport improvements and USS is supportive of an integrated transport solution and the benefits this will bring for the city centre. However, the Local Plan should recognise that such a solution will likely take many years to deliver and in the interim there should not be onerous restrictions on the existing modes of transport that are used to access the city centre.

We have major concerns regarding Drainage and suggest:

• All planning applications must have evidence that the proposed development will have appropriate drainage facilities, not only for the curtilage of the development but also for the rest of the community

• That it shall be a condition of all applications that the build conforms with the proposed drainage arrangements and this conformity requires independent inspection on completion with enforcement action if it does not.

• A requirement for the developer to ensure ongoing responsibility in perpetuity (i.e. for a period of 25 years) for the necessary maintenance of the drainage system to maintain its operating performance

• Notification of the power of the local authority to inspect maintenance is properly undertaken, and if not to seek immediate restitution..

Also, for Darwin Green 3 there needs to be proper control over drainage aspects of planning. We note our vulnerability due to being downstream of the proposed Darwin Green 3 large scale development which will drain through our community through a single award drain, the environs of which are already designated as high risk flood areas by the Environment Agency.

Also, Infrastructure needs to be in place before work starts to prevent new homes not having infrastructure at move date.

Hallam Land Management (HLM) support the Councils aims in respect of infrastructure, however it considers the Plan should allocate circa 8.6ha of land at Scotland Farm for the Scotland Farm Travel Hub. A site location plan and illustrative masterplan is appended to these representations. Information on this site has been submitted separately through the call for sites additional site information portal.

C2C is a key part of the Greater Cambridge Partnership’s sustainable transport programme.
Scotland Farm Travel Hub is a key element of the C2C route. Work is already underway in preparing the planning application, and the site is expected to be operational by 2024.

In light of the stated intention to bring this development forward as an important component of the sustainable transport infrastructure for the area, this should be recognised within the Plan and the land allocated accordingly.

Support, but be aware of effects on landscape

Paragraph 22 of the NPPF states “Strategic policies should look ahead over a minimum 15 year period from adoption, to anticipate and respond to long-term requirements and opportunities, such as those arising from major improvements in infrastructure. Where larger scale developments such as new settlements or significant extensions to existing villages and towns form part of the strategy for the area, policies should be set within a vision that looks further ahead (at least 30 years), to take into account the likely timescale for delivery.”

In addition, the NPPF (at paragraph 73) states that the supply of large numbers of new homes can often be achieved through planning for larger scale development, including significant extensions to existing towns, provided they are well-located and designed, and supported by the necessary infrastructure and facilities.

The spatial development of Cambridge to date partly reflects a lack of transport investment; therefore, Marshall supports the GCSP’s policy intent to focus on planning for the right services, facilities and transport opportunities in the right place, and bringing these forward at the right times to support the delivery of housing and employment.

Marshall extends it support to the Local Plan’s intention to distribute development to locations that can make the most of existing infrastructure and that present opportunities to address any infrastructure deficits. The infrastructure deficit in the east of the city can only be transformed through a partnership of co-ordinated public sector working and high quality new development planned on a scale to incorporate infrastructure of real value.

Cambridge East is identified in the transport evidence base reports as offers the opportunity to plan for both housing and employment at a scale which would provide a substantial contribution to the future needs of the city. The site provides an opportunity to deliver transformational solutions that unlock the investment needed in transport infrastructure to fix its economic geography. It provides the opportunity to improve connectivity to the city centre via a segregated link to the station, as well as improved connectivity to the existing clusters in the north and the south. This would result in benefits to residents – reduced journey times and reduced congestion – but also would create economic benefits by increasing the effective density of the city, making jobs effectively closer to each other, resulting in productivity benefits. The level of transport improvement that is possible will depend largely on the scale of development at Cambridge East. Commercial space and homes result in more transport journeys and therefore require more investment in transport, whilst making that investment more viable.

It is noted that the provision of infrastructure to facilitate new development and to ensure that this can be accommodated in the target locations (primarily in the large-scale growth areas and new settlements to the north of Cambridge, at Northstow and at Cambourne). However, it is not considered that sufficient attention has been given to the role of existing infrastructure and how locations in the GCLP area which are currently well-served by public transport links can contribute to sustainable growth.

The role of Meldreth Station and other public transport nodes, particularly those which provide access to rail services, is not given sufficient prominence. As highlighted above, the fact that settlements benefitting from convenient access to the rail network do not have greater prominence as a focus for sustainable development represents a significant missed opportunity. There is an opportunity to address this by recognising the potential of existing infrastructure to accommodate growth which is proportionate to the scale of the settlement.

Please see additional written representations for further details.

The Cambridge Biomedical Campus and immediate area will benefit from significant planned improvements in transport infrastructure, including from the Cambridge South Station and CSET extension. It is an appropriate, sustainable location at which to plan further development.

Planning at scale enables the greatest opportunity to achieve modal shift.

The expansion of the Campus into the identified Area of Major Change is an opportunity to bring development at a scale that can provide access to new infrastructure to address existing deficits, in a location that can reduce rather than add pressure to existing transport networks.

The document provides a list of new technologies but does not address the supply of utilities. The Local Plan document comments on the need for grid reinforcement but there are no comments for example in the Local Plan regarding continuing use of Natural Gas or conversion to hydrogen. Water supply and sewage handling does not appear to be considered although they are an essential part of infrastructure provision, the same is true of “green infrastructure”.

It is not clear to me that school and college journeys have been taken into account in determining transport needs. This is particularly important in relation to Greater Cambridge in that, in particular, sixth form students travel into Cambridge’s two large sixth form colleges and Cambridge Regional College from all over Cambridgeshire. Cambridge Academy of Science and Technology has an even wider catchment area. These education-related journeys are not covered in the Greater Cambridge Local Plan Existing Transport Conditions Report.

The public transport journey time between Cambridge and Peterborough is not currently competitive with a private car journey time.


As regards the I/ID section of the infrastructure topic paper:

(a) East West Rail’s preferred route misses the opportunity to serve communities beyond Cambourne, such as Northstowe. It does not align well with the development plans in the First Proposals and is very much at odds with GCSP’s proposed policy J/AL “protecting the best agricultural land” - see https://cambridgeapproaches.org/ewr-impact-on-farming-and-uk-food-security/ ;
(b) the current proposals for CSET do not align well with the Cambridge Biomedical Campus and Babraham Research Campus-related development plans in the First Proposals and with the Green Infrastructure policy BG/GI designation of Gog Magog and the Chalkland Fringe as an area worthy of special protection. Nor does CSET, as currently proposed, serve the villages of Great Shelford, Stapleford and Sawston in any realistic sense. These proposals are also insufficiently ambitious as regards the Biomedical Campus staff who live in Haverhill and surrounding villages and likely simply to push congestion out of Greater Cambridge and beyond the new Park and Ride. The lack of interchangeability arising from the different system of guidance to be used for CSET means that the vehicles will not be interchangeable with buses used on the existing guided busway. This seems an odd decision, as does the fact that it is unclear how CSET buses will proceed into the centre of Cambridge. It is also unclear whether the plans for CSET take into account the ambition of Cambridge University Hospitals NHS Foundation Trust (“CUHFT”) to move its accident and emergency department across the Biomedical Campus, as part of its Addenbrookes 3 proposals;
(c) the Chisholm Trail should be extended to Whittlesford;
(d) this paper does not cover health infrastructure and, most particularly, the hospital infrastructure appropriate to meet the health needs of the growing and ageing population of Greater Cambridge, including as contemplated by the First Proposals, and any proposed expansion of the Cambridge Biomedical Campus;
(e) the Infrastructure Development Plan will need to cover timetables and sources of funding for health and educational infrastructure, including government funding and test how realistic proposals are.
.

The plan fails to optimise the distribution and location of proposed housing in relation to existing rail connectivity as at Whittlesford. Refer to Grosvenor's main representations on the spatial strategy and RSC.

Reiterating a point made earlier, Great Shelford Parish Council feels strongly that there is little joined up thinking when looking at the infrastructure projects for the area which various authorities are undertaking.

In addition, the planning authority is assuming approval will be given for transport infrastructure such as CSET, which has not yet gone for planning approval, which will not benefit the community of Great Shelford at all. Indeed, GSPC is opposed to the current CSET plans.

Infrastructure – general comments In areas of significant housing growth, appropriate funding must be consistently leveraged through developer contributions for health and care services in order to meet growing demand. We request that when setting planning obligation policies, the Council seek to address strategic as well as local priorities in planning obligations and engage the NHS in the process as early as possible.
We note the early ‘Infrastructure Delivery Plan - Supplement’ document, which identifies the need for up to 14.7 GP’s and 3086sqm floorspace for primary health infrastructure in response to the growth proposals.
We are keen to engage with the Council, and their advisors, to review and update these figures once there is clarity over the amount and location of growth proposals, and accurately assess the impact on existing health infrastructure, and what additional capacity (by way of adaptations, extensions and new build facilities) will be required.
A vital part of this is ensuring the NHS continues to receive a commensurate share of S106 and Community Infrastructure Levy (CIL) developer contributions to mitigate the impacts of growth and help deliver transformation plans.
The significant cumulative impacts of residential developments on healthcare requirements in the area should be recognised and, given their strategic importance, health facilities should be put on a level footing with affordable housing and other infrastructure providers when reviewing, securing and allocating S106 and CIL funds, in order to enable the delivery of vital NHS projects. It is imperative that planning policies are positively prepared, in recognition of their statutory duty to help finance improved healthcare services and facilities through effective estate management.

We have concern about WiFi Broadband provision. In our village the signal is still not up to scratch and often drops. This should be a priority not least because it will support home working and jobs.

Cambourne Town Council supports the theme as it addresses the aims contained in the vision.

You must rigorously enforce all developer obligations and not allow retrospective excuses.

INFRASTRUCTURE
CLEF notes the sustainable transport plan and the acknowledgement that the regional bus system is in the purview of the Combined Authority, which is planning more active travel modes. However, there is no schedule for alternative modes of transport and we cannot afford to wait for the end of the period covered by the plan to institue this. Indeed, many of these proposals seem to be contingent on development and developers. The current public transport bus system fails to meet past or current needs and requires immediate low-carbon improvements.
This includes eliminating private car use around the city with an integrated (electric) public transport system which would: cut congestion and commuting times as well as help reduce air pollution and its related health problems; improve the street and living environment for Cambridge residents; and cut CO2 emissions. This would be a major symbol of Greater Cambridge's determination to safeguard the environment and tackle the climate crisis. Our regional reliance on the car persists: in London, where public transport is very good, car ownership is 45% - in Cambridge City it was 66% in 2011 (in Cambridgeshire, it was 89%). In 2018, the region had the highest rate of car ownership of all English regions (1.4 cars per household).
The growth assumed in the Local Plan does not explain how public services (for example in health and social care) are going to cope with the substantial projected population growth, given continuing cuts in government financial support. This only exacerbates pressure on the poorer parts of the community more dependent on public as opposed to private provision.
There are no clear plans for renewable energy, green infrastructure and reduced car dependence in the local plan. For example, for developments of under 100 homes (and an unspecified size of industrial development) there will be no requirement to include an assessment of the capacity of infrastructure to support the development. There is no guarantee that those buying the new homes will be those working/studying within the proposed 30-minute walking radius. With cars (including electric cars) getting heavier and homes being heated to ever highertemperatures (see Absolute Zero Report), the burden on energy supply rises.

Shepreth Parish Council (SPC) believes that any development in the context of the local plan should benefit and expand the surrounding infrastructure and not be a burden on already overloaded waste and sewage networks in particular.

Introduction
Thank you for consulting Central Bedfordshire Council (CBC) on the first proposals consultation for the Greater Cambridge Local Plan 2041. Please accept this letter as our formal response. We welcome the opportunity to respond to the proposals in this consultation and look forward to continuing the good working relations that CBC has already forged with the two substantive authorities. We have provided some comments below on the consultation documentation which we hope are useful. Please do not hesitate to contact us if you have any further questions.

General Comments on Strategy

Overall, the Council supports the approach you have taken in terms of undertaking a joint local plan to ensure a consistent approach to planning and building across both Cambridge City Council and South Cambridgeshire District Council up to 2041.

We support the proposed Vision for the Greater Cambridge Plan especially as it places climate impacts at the heart of key decisions. It states that Greater Cambridge will be a place where a big decrease in your climate impacts comes with a big increase in the quality of everyday life for all your communities. It also promotes new development minimising carbon emissions and reliance on the private car; creating thriving neighbourhoods with the variety of jobs and homes you need; increasing nature, wildlife and green spaces; and safeguarding your unique heritage and landscapes. CBC considers this to be a laudable, succinct overarching Vision that we hope you will be able to carry through to effective policy and decision-making on the ground.

CBC considers that the proposed strategy outlined within the First Proposals could help ensure that Greater Cambridge makes a valuable contribution to the Oxford to Cambridge Arc and to the overall delivery of the Government’s ambitious growth aspirations. However, the Council considers that it would be useful to include reference to the emerging Arc Spatial Framework, identifying that alongside the NPPF, this will set the overarching strategic framework for the area with which all local plans within the Arc must accord. CBC would be keen to understand the timescales for the delivery of the Greater Cambridge Plan and how the emerging Spatial Framework will be taken into consideration to inform future iterations of the plan.

We appreciate that the Plan is at an early stage of development, and at the current time you are considering locations that could be delivered alongside allocated sites being carried forward from the adopted 2018 Local Plans for Cambridge and South Cambridgeshire, as well as sites which already have planning permission.

We note that you are proposing to meet in full your objectively assessed needs of 44,400 new homes to 2041, which is supported by CBC and is necessary to ensure needs can be met across the area.

CBC recognises that Cambridge has seen significant economic and jobs growth in recent years and that there is an ambition to maintain this direction of growth as the impacts of the recent pandemic subside. As stated in our comments made in response to your Issues and Options Consultation in February 2020, we would not support a level of jobs growth that could detrimentally impact upon the ability of neighbouring authorities, such as Central Bedfordshire, to meet and deliver their own economic ambitions and growth aspirations. CBC therefore supports the housing numbers proposed to meet the OAN and the identified buffer and welcomes the move away from the higher job number which were put forward in your Issues and Options consultation. We agree that the higher jobs forecast previously considered would not be the most appropriate scenario to pursue. Overall, CBC considers that the proposed level of housing of 44,400 new homes and complementary economic growth of 58,500 new jobs across all sectors including business, retail, leisure, education and healthcare, is an appropriate level of growth to deliver for over the plan period.

The First Proposals have suggested 19 new possible locations that might be suitable for additional development to meet your needs across the Greater Cambridge area up to 2041. Overall, CBC supports the proposed approach taken to the geographical spread of these sites and welcomes the inclusion of sites in the most sustainable locations around the Cambridge urban area and on the outskirts of the City, where existing and future residents can take most advantage of the proximity to jobs and services using public transport and active travel options. The proposals to direct development to where it has the least climate impact, where active and public transport is the natural choice is logical and fully supported.

It is noted that the consultation material suggests that the majority of your objectively assessed need can be provided for in the core preferred strategic sites of North East Cambridge, Cambridge East and Cambourne. This approach is supported as the locations will reduce potential climate impacts through the delivery of well connected, sustainable, compact development where active and sustainable travel can be maximised.

CBC have not provided detailed comments on all of the proposed 19 sites included within the consultation material but note the proposals for new strategic scale development at Cambourne which lies in close proximity to Central Bedfordshire. It is noted that in total, there are 3 development sites proposed for Cambourne - two of these are existing allocations; Cambourne West which has capacity for 2,590 units and Bourn Airfield which has capacity for 2,460 units, alongside a new proposed broad location for growth at Camborne - expected to deliver 1,950 homes.

CBC recognises that whilst a final decision has not yet been announced, the preferred East West Rail route between Bedford and Cambridge will likely result in a new stopping station at Cambourne and that this will transform the area, maximising sustainable opportunities for growth. Whilst we support the opportunities that the proposed new station would potentially bring, CBC would suggest that any future transport impact assessments and traffic modelling associated with the proposals should consider the cumulative impacts of both existing and proposed development at Cambourne and any implications for the wider area, including potential impact upon the strategic and local road network within Central Bedfordshire. It is likely that there will be cumulative impacts from growth at Cambourne on communities within CBC related to an increase in demand on the A1, particularly if / when the A428 dualling and Black Cat works are carried out, and also the more minor roads through areas like Potton, Sandy, Biggleswade. Whilst outside of the Greater Cambridge plan area, the capacity of the A1 in this area is already a key concern that affects a much wider area and must be considered carefully and comprehensively when decisions are being made in relation to future growth.

We would, therefore, welcome further engagement to understand the scale of those impacts and their likely implications for Central Bedfordshire communities as the work on the local plan and the sites themselves, progresses. We would welcome being involved in early engagement with National Highways in relation to these impacts. We would also be keen to look at opportunities to secure sustainable links (via public transport) between CBC and the development areas to the west and south of the Greater Cambridgeshire area.

As noted above, whilst a formal decision is yet to be announced in relation to EWR between Bedford and Cambridge, or indeed the location of a new stopping station at either Tempsford or to the south of St Neots, CBC consider it essential that the Greater Cambridge Plan considers the wider context of strategic growth within the Arc, particularly in terms of future connectivity opportunities that will undoubtedly arise as proposals within neighbouring authority areas emerge. Your approach to enabling some development within smaller villages is supported as this will support rural services and the vitality and viability of villages and their shops and services contributing to overall sustainability. We appreciate that it is unsustainable to encourage high levels of growth where car travel predominates and that therefore, in smaller villages you will continue to support infill development and affordable housing on suitable sites only. This approach is supported, especially given the very rural nature of the areas close to the Central Bedfordshire border.

The 7 Themes
We welcome the approach taken in this consultation to identify 7 key themes and we have provided some high-level comments on each of them below. It is understood that each of the themes will influence how you will plan homes, jobs and infrastructure and ultimately where growth will be directed. In our previous response to the Issues and Options stage of consultation (February 2020) we suggested that “connectivity” both within and beyond the Greater Cambridge area should perhaps be considered as an additional theme. Whilst we note this suggestion has not been taken onboard, CBC considers that connectivity is the ‘golden thread’ that runs through all the key themes and could potentially be referenced as such within the Greater Cambridge Plan.

Climate Change
We support your aim to help Greater Cambridge to transition to net zero carbon by 2050 through a number of comprehensive measures including ensuring that development is sited in places that help to limit carbon emissions, is designed to the highest achievable standards for energy and water use and is resilient to current and future climate risks. It is clear that responding to climate change has influenced the shape of the plan as an important factor in determining where future development should be located and how it should be built. CBC would be keen to have future conversations to share experiences and to understand how net zero carbon can be achieved in terms of viability, and to explore how this can be monitored to ensure the approach is successful. In terms of detailed policy, Policy GP/QD could benefit by also referring to building orientation to maximise the opportunities for renewables.

Biodiversity and Green Spaces
We support your aim for biodiversity and green space policies to increase and improve your extensive network of habitats for wildlife and green spaces for people, ensuring that development leaves the natural environment better than it was before. We also welcome confirmation that the Oxford to Cambridge Arc Environmental Principles have informed your approach to this theme, in particular, we welcome and support the ambitious policy to require 20% Biodiversity Net Gain. As this will be an issue for all Local Authorities within the Arc, CBC would also be keen to discuss how this could be delivered and the impacts this might have not only on site viability, but
the delivery of other key services and facilities across the Arc .

Wellbeing and Social Inclusion
We support your aim of helping people in Greater Cambridge to lead healthier and happier lives ensuring everyone benefits from the development of new homes and jobs.

Great Places
We support your aim for the delivery of great places through policies that sustain the unique character of Cambridge and South Cambridgeshire and compliment the area with beautiful and distinctive new development, creating a place where people will want to live, work and play.
The themes from the Cambridgeshire Quality Charter for Growth covering the four “Cs” of Community, Connectivity, Climate and Character is a sensible approach consistent with the National Model Design Code.

Jobs
CBC supports the aim of your proposed jobs policies in terms of encouraging a flourishing and mixed economy which includes a wide range of jobs while maintaining the areas global reputation for innovation. The Council considers the policies are positive and forward thinking in the current climate in that they seek to reflect how the approach to working environments is changing, by supporting remote working and improving facilities on employment parks.
We support the inclusion of a remote working policy but consider that it could be strengthened to refer to the provision of home office space in new dwellings as the emphasis is currently on the delivery of external hubs or extensions of existing dwellings.

Homes
As commented above, the Council supports the proposed strategy to plan for and deliver enough housing to meet your objectively assessed needs, including significant amounts of affordable housing and a mix of tenures to suit your diverse community’s needs. The proposed policy requiring 40% affordable housing in new developments is particularly supported.

Infrastructure
We support the approach taken that the relationship between jobs and homes and sustainable transport opportunities has been a key consideration and influence of the development strategy proposed. Recognising that infrastructure is not limited to the provision of new roads, CBC also supports the recognition for the need to consider and plan for water, energy and digital networks, and health and education and cultural facilities in the right places and at the right times to ensure your growing communities are supported. Looking to the future, your policies on electric vehicle charging points and digital infrastructure will be key given the need to move away from carbon-based vehicle fuels and the shift to homeworking that has been accelerated by the pandemic. We also note that whilst there is an objective for Air Quality within the Sustainability Appraisal, there is no objective included for Transport and Access.

We welcome this opportunity to comment on this latest stage of your development plan proposals and largely offer our support to the approach you have taken. We also appreciate how you have digitally presented and structured the documentation in order to make it as accessible as possible to everyone. The use of maps and diagrams throughout the document is an effective way of setting out the context and portraying the information within the text. In addition, the ability to explore the documentation through the “themes” and “maps” is a particularly helpful way of organising the consultation.
I hope you find these comments useful and look forward to continued engagement as your plan progresses.

Compendium of Environment Agency Comments

Vision and aims
The vision on page 20 is positive bringing to the forefront decreasing climate impacts, minimising carbon emissions, increasing nature, wildlife and green spaces. Reflecting on the paragraph on page 18, you outline the aim for the Local Plan is simple: to ensure sustainable development. This means planning for homes, jobs and supporting infrastructure in the right places, alongside protecting and enhancing the environment. We recommend the vision reflects this objective of ‘sustainable development.’ For example, we suggest the following revision as follows: New development must be sustainable: minimise carbon emissions and reliance on the private car; create thriving neighbourhoods with the variety of jobs and homes we need; increase nature, wildlife and green spaces; and safeguard our unique heritage and landscapes. This will align closely to the aims of the NPPF (paragraphs 7 and 8) and also demonstrate the importance of this for Greater Cambridge given the unique challenges and opportunities the area faces.

We support the references within the aims to highest achievable standard for water use and resilient to current and future climate risks. The biodiversity and green spaces aim is also positive in its focus on improving the network of habitats and ensuring development leaves the natural environment better than it was before. All these aims will help GC achieve the stated vision and it’s important that the interrelationship and interdependencies between these aims are recognised. Recognising the interdependencies will strengthen and ultimately achieve better outcomes for GC. One example is the ecological health and water quality of rivers and water dependant habitats (e.g. wetlands) is also dependent on the availability of water in addition to the contribution developments will make in creating and enhancing habitats and green space. Healthier rivers and water dependant habitats will in turn restore nature, improve the health and wellbeing of communities and have economic benefits. Serving the environment in tandem with growing communities is mutually beneficial and secures long-term resilience. This also reflects the paragraph 153 of the NPPF: ‘plans should take a proactive approach to mitigating and adapting to climate change, taking into account the long-term implications for flood risk, coastal change, water supply, biodiversity and landscapes’ etc.

S/DS Development Strategy
We welcome the section on ‘Ensuring a deliverable plan – water supply’ on pages 41 and 42, which recognises this as a significant issue for the Local Plan. We remain genuinely concerned about whether the growth proposed (48,800 new homes inclusive of 10% buffer and 37,200 from previous plans) can be sustainable without causing further deterioration to the water environment. We understand the regional and water company water resource planning is still ongoing and the next version of the IWMS Detailed WCS will be updated as these plans come to fruition. We offer our support to work collaboratively with all the parties involved.

Current levels of abstraction (not just in Cambridge) are causing environmental effects. Increase in usage within existing licenced volumes will increase the pressure on a system that is already failing some environmental targets. The Anglian River Basin Management Plan shows many waterbodies do not have the flow required to support the ecology. Abstraction licencing reductions are likely to reduce the supplies available to water companies in our efforts to prevent deterioration of the water environment. As the plan and evidence base progresses it will need to be clearly demonstrated that the water companies plans can meet the needs of growth without causing deterioration.

As a best case scenario the strategic water infrastructure (new Fenland reservoir) would be available from the mid-2030s and its foreseeable this could be later i.e. the 2040s. It is the short to medium term period coinciding with the majority of the plan period for which rapid and viable interim solutions are needed. There is currently uncertainty about whether water supplies can be provided (both supply and demand management) in a way that is both sustainable and sufficient for the proposed growth over the plan period.

We support the idea of development limited to levels that can be supported by a sustainable water supply (phased delivery) until the time the strategic infrastructure is in place, though we are mindful this may lead to heavily back loaded delivery. If the Council approaches neighbouring local planning authorities as you already recognise it is likely they will have similar issues, though some may have more options for interim solutions. This highlights the importance of cooperating across planning boundaries and growth plans being considered in the context of the combined pressure on water supplies at a regional scale. As previously mentioned, 2050 may be a more appropriate end date for the plan period given the challenges being faced which in reality require a longer lead in time to support development, e.g. strategic water resources infrastructure, climate change resilience, etc. This would also align with paragraph 153 of the NPPF ‘plans should take a proactive approach to mitigating and adapting to climate change, taking into account the long-term implications for flood risk, coastal change, water supply, biodiversity and landscapes’ etc.

Integrated Water Management Study – Outline Water Cycle Strategy
The WCS will rely on further evidence coming forward from both regional and water company water resource plans. The WCS will need to demonstrate that feasible and deliverable mitigation measures are available for the interim period until new strategic water resources options will come online.

As noted, the WCS will need to base its assessment on the forthcoming water resource plans (WRMP24) rather than the existing, as this will have a more accurate picture of the water resources situation taking into account abstraction licence reductions. Both Cambridge Water and Anglian Water are likely to require further sustainability reductions in PR24. This could mean some or all of the current water surplus’s (available headroom) are no longer available for transfer.

The reliance on demand management options is currently high-level. These will require assessment of feasibility, effectiveness and how implementation will be monitored and measured corrected if they are not working.

In facing what is collectively a significant challenge we offer our support to work collaboratively with the interested parties ahead (and beyond) the next consultation in 2022.

S/NEC: North East Cambridge
We note the intention of the policy is to set out the place-making vision and a robust planning framework for the comprehensive development of this site. There are both environmental risks and opportunities to developing this site sustainably. Ensuring sustainable water supplies, improving water quality and the effective remediation of land contamination will be key considerations in achieving this. The proposed policy direction anticipates the site (once developed in full, which will extend beyond the Local Plan period of 2041) will deliver 8,350 new homes. The IWMS Detailed WCS will need to provide evidence the new homes (and employment) can be sustainably supplied with water in time for the development phases.

The existing site at Fen Road, Chesterton continues to be a source of ongoing local water quality and environmental health problems due to inadequate foul drainage provision. There have been a number of reports of foul sewage from the site discharging into the River Cam, causing chronic on-going pollution. The relocation of the existing Milton sewage works and extensive redevelopment of North East Cambridge presents the opportunity to incorporate mains drainage connection into the Fen Road site.

Policy S/NS: Existing new settlements
With regard to the existing allocations NS/3 and SS/5 Northstowe, we are investigating flood risk management options to reduce the risk of flooding in Oakington. This will take account of measures looking to attenuate water upstream (on the upper reaches of Oakington Brook and as part of the Northstowe development), potential channel modifications and natural flood management. We note that early phases of Northstowe are under construction. We recommend the emerging policies include this as an opportunity both in terms of delivering flood risk management measures or securing financial contributions towards this project.

CC/WE: Water efficiency in new developments
We support stringent water efficiency in water stressed areas. We recommend reviewing the document The State of the Environment: Water Resources (2018) prepared by the Environment Agency. This document outlines the challenges we now face summarised as follows. Water supply (resource) is under increasing pressure from population growth, land use change, and climate change (including hotter weather increasing evaporation, less rainfall in summer, and intense rainfall events not recharging aquifers efficiently). Without increasing our supply, reducing demand, and cutting down on wastage many areas will face significant deficits by 2050, if not sooner. If not addressed this represents an immediate and measurable blocker to future growth. We need to consider development in the context of available water resources, balancing economic growth with protecting and enhancing the water environment. We will need to ensure that there is enough water for both people and the environment, that water is used efficiently, that water is protected as a precious resource, and that wastewater is treated efficiently to cut associated carbon emissions.

We agree the evidence of the water resources situation in Greater Cambridge justifies the tighter standard of 80 litres/person/day for housing. The risk of this standard not being met is an increase in abstraction risking deterioration of associated water bodies. As page 150 recognises (with reference to the Deregulation Act 2015) GC Council will need to be satisfied that this standard can be legally and practically implemented in the context of current legislation (Water Industry and Development Industry), national policy and building regulations. This affects the practical implementation of this policy. It would need to be determined the evidence/metric applicants would be expected to submit to demonstrate this standard has been achieved. It would also need to be evidenced how the policy standards would be implemented, and how this would be monitored to ensure the policy is effective.

A positive standard is proposed for non-residential development, which we support. Water neutrality should also be explored, noting the references made to water reuse and offsetting.

The Integrated Water Management Study (IWMS) states that 80 litres/person/day is achievable by making full use of water efficient fixtures and fittings, and also water re-use measures on site including surface water and rainwater harvesting, and grey water recycling. It comments that the cost effectiveness improves with the scale of the project, and that a site-wide system is preferable to smaller installations.

Currently the policy direction has a caveat of ‘unless demonstrated impracticable.’ This should be explored further in the WCS so the Council has clear guidance on the circumstances where achieving this standard would be impracticable. This will help ensure planning applications can be fairly and reasonably assessed. This will also help ensure the overall goal of the policy is not weakened or undermined. Similarly this evidence needs to be drawn out for the non-residential standard. The WCS should also set out the backstop position should the standard of 80 litres/person/day be practicably unachievable.

Although we support water efficiency measures in new development, we consider that the plan is currently unlikely to achieve the kinds of reductions in demand needed to keep the proposed levels of growth within sustainable levels. As noted with policy S/DS, the evidence base (IWMS Detailed WCS) will need to demonstrate how the water companies’ plans can meet the needs of growth without causing unsustainable abstraction and associated deterioration. We offer our support to work on this collaboratively with the interested parties both ahead of the next consultation in 2022 and beyond.

Page 150 references the Shared regional principles for protecting, restoring and enhancing the environment in the Oxford-Cambridge Arc. We recommend this is also considered and referenced elsewhere in the plan with regards to net zero, net gain, tree cover and strategic resource infrastructure provision.

CC/DC: Designing for a changing climate
The proposed policy intends to set out how the design of developments should take account of our changing climate, for example, extreme weather events including flash flooding. We welcome the reference (p. 152/153) to site wide approaches to reduce climate risks, including sustainable drainage systems as part of landscape design, urban greening, increased tree canopy cover and integrating green spaces into new developments. In the context of flooding and climate change it would also be appropriate to reference flood resistance and resilience measures (see PPG: https://www.gov.uk/guidance/flood-risk and-coastal-change#Flood-resilience-and-flood-resistance). Site wide approaches should also include adaptive measures such as setting a development away from a river so it is easier to improve flood defences in the future. In addition, making space for water to flood and be stored will be critical to long term adaptation. Planning to avoid future flood risk is as much about creating storage or contributing to nature based flood risk reduction measures (e.g. creating wetland habitats) as it is avoiding flooding to new properties.

In shaping this policy, we recommend GC Council also consider the ADEPT local authority guidance on preparing for a changing climate (2019) and the new TCPA The Climate Crisis, A Guide for Local Authorities on Planning for Climate Change (October 2021).

The Fens Baseline Report (available at https://www.ada.org.uk/knowledge/future-fens/) indicates that rising sea levels to 2115 will mean water will not drain by gravity to the sea, requiring the pumping of vast quantities of water. The carbon and engineering implications of this are significant but not yet calculated. There is a compelling case for surface water to infiltrate into permeable ground ensuring that water resources are not depleted of water. In areas of less permeable geology, net gains in surface water attenuation and re-use of the water as ‘green water’ in homes, businesses or agriculture has been considered through this study.

CC/FM: Flooding and integrated water management
We welcome the inclusion of Policy CC/FM. We agree a policy that responds to the local water management issues is needed. As climate change will intensify the existing pressures on water availability, water quality, drainage and flood risk an integrated approach to water management will be essential. As stated this should include a robust approach to drainage and water management. The proposed policy direction is a good starting point but given the water challenges (our comments to Policy S/DS) it should strive to secure both mitigation and betterment through growth.

The local policy approach should be informed by the IWMS Water Cycle Studies, the Level 1 SFRA and other relevant strategies. We would expect to see the policy content evolve with the following considerations:

1) Though the policy direction indicates that policies will require that the risk of flooding is not increased elsewhere, it should seek to secure betterment and reduce flood risk overall, wherever possible, as part of GC’s strategy to adapt to climate change. This aligns with our previous comment that making space for water to flood and be stored will be critical to long-term adaptation. Floodplain storage, natural flood management and surface water attenuation are all measures that will contribute. Protection of potential flood storage land (including functional floodplain/Flood Zone 3b) and financial contributions towards flood risk schemes could also benefit communities at risk of flooding are also much needed options. Although many sites are located in Flood Zone 1 (low probability of flooding from rivers) there are also many sites located on the fringes of Flood Zones 2 and 3 meaning these are at risk of reducing (potentially eliminating) future flood storage options for adapting to climate change. In the background, urban creep and small infill developments which do not attenuate for surface water impact drainage systems and watercourses downstream. In planning to manage future flood risk in GC, creating extra storage to allow space for flood waters is a vital element of that plan.

2) We expect the policy to include provision for water supply and waste water infrastructure, ensuring water quality and treating and re-using waste water. We recommend that the provisions of Policy CC/7, ‘Water Quality’, of the South Cambridgeshire Local Plan 2018 are considered and brought forward into the Greater Cambridge Local Plan. Site policies may also need to include specific infrastructure requirements. These should become apparent, and be informed by, assessments carried out in the IWMS Detailed Water Cycle Study.

3) There needs to be a policy approach that recognises a clear integration encompassing water resources, water quality, flood risk and recognising the role of green infrastructure. Although the value of green infrastructure and river corridors is recognised in policy BG/GI and BG/RC, it is worthwhile including it as part of the integrated water management policy. The Greater Cambridge Green Infrastructure Opportunity Mapping Study touches upon this relationship under the Water Storage bullet as follows: Our rivers are a source of flood risk. Restoration of natural flood plains where practicable and provision of green infrastructure can help reduce flood risk along the rivers itself and beyond. Wet woodland will self set and grow where conditions are right and management allows. Providing the right conditions for trees to grow in appropriate locations in river corridors can support flood risk mitigation and biodiversity.

Integrated Water Management Study – Outline Water Cycle Strategy (WCS)
For water quality we welcome that the Outline WCS has been amended based on our previous feedback. However a number of issues raised remain unresolved which we can expand upon in a more detailed response to the Council’s consultants. Some of the information presented does not represent the proper ‘baseline’ for subsequent assessments and the extent of the challenge of delivering the quantum of growth proposed in the Local Plan. For example, 2019 WFD classification data is presented but waterbody objectives are from 2015, also the information in chapter 6 does not take account of river quality improvements delivered by AMP6 or AMP7 schemes. The identified assessment methods need to be sufficiently robust, and potential mitigation actions will need to be shown to be viable. The Detailed WCS will need to provide evidence to demonstrate the delivery of foul drainage provision can be provided whilst protecting water quality of rivers.

Climate change topic paper (IWMS Level 1 Strategic Flood Risk Assessment)
We have reviewed the Level 1 SFRA. The majority of sites are in fluvial Flood Zone 1 with a proportion of sites with partial Flood Zone 2 and 3 either within the site boundaries or close to boundaries. Surface water flood risk also affect most of the sites to a limited or greater extent. Flood risk and climate change adaptation is an important consideration of the Local Plan in view of the predicted impacts of climate change on flood risk. Page 39 of the Climate Change Topic Paper states that the Level 1 SFRA (2021) has been used to support the selection of development sites through the application of the Sequential Test. This statement within the topic paper is helpful, however, it does need to be more obviously demonstrated how the Sequential Test and sequential approach to all forms of flooding has been applied. The Planning Practice Guidance advises a number of options for this including a standalone report, Sustainability Appraisal commentary, etc. This will need to be produced in time for the next draft plan consultation so it is clear how the test has been applied and demonstrated.

Page 42 explains that where necessary a Level 2 SFRA of sites in the draft plan will be carried out to ensure that designs and capacity fully reflect management of flood issues. We think that a Level 2 SFRA is necessary particularly for those sites located on the fringes of Flood Zones 2 and 3, or partially within those zones. In predominantly flat or fenland areas, breaches in flood defences can cause flooding in Flood Zone 1 due to the concentration of floodwater in one part of the floodplain, for example, the Waterbeach New Town allocation. Some sites have unmapped ordinary watercourses running alongside or through them and often these have not been modelled as part of the indicative flood map due to their limited upstream catchment size. As such there is some uncertainty over the level of flood risk to the site, with the potential that fluvial flood risk may be greater than the Flood Map for Planning. These sites will 7 require further investigation to better refine the flood extents (including climate change) preferably by flood risk modelling or utilising the Flood Map for Surface Water (FMfSW). For some sites, fluvial climate change assessment is required as this is not modelled.

A Level 2 SFRA could also identify suitable land or techniques that could be used for flood storage to adapt to climate change and urban creep. Even if these cannot be brought forward at this stage in the plan, these could be protected for future plans or for infrastructure to bring forward at the appropriate time. The LLFA may also have areas of surface water flooding to be further investigated. The Level 2 will help determine whether the site can be developed safely, mitigation measures required, sequential approach and applying the Exceptions Test (NPPF paragraph 164). The Level 2 SFRA should inform the site specific polices within the plan that will form the planning framework for the sites. We can provide a separate list of the sites we think would require L2 SFRA assessment if helpful.

BG/BG: Biodiversity and geodiversity
This policy will control biodiversity impacts from development and set out Biodiversity Net Gain requirements (aiming for 20% BNG). We welcome and support the Council’s policy direction on this. It should be clear that BNG is in addition to the standard requirements of the mitigation hierarchy i.e. avoid harm where possible, mitigate for the effects or compensate (paragraph 180 of NPPF). We recommend that local authorities adopt a natural capital evidence approach to underpin their local plan. This is mentioned briefly in the evidence base within the green spaces topic paper. Information can be found here. Natural Cambridgeshire have done some work in this area, looking at opportunity mapping. Also, the recent Oxfordshire Plan 2050 (Reg 18) had some good natural capital and ecosystem services wording (policy option 09) that we recommend you consider. Preparation of a natural capital evidence base and policy is something we (and likely Natural England) could advise on in advance of the next consultation stage.

Wider environmental net gains is also identified as a potential policy requirement which we support, and pending further guidance from a national level. We recommend that geodiversity is also considered.

We recommend ambitious maintenance requirements to protect and ensure longevity of net gain enhancements. The Environment Bill mandates 30 years but ‘in perpetuity’ should be aimed for where possible.

The proposed policy direction includes that off-site measures must be consistent with the strategic aims of the Greater Cambridge green infrastructure network strategic initiatives. We welcome the GI initiatives so far identified within the GC Green Infrastructure Mapping which include revitalising the chalk stream network, the River Cam corridor and enhancement of the fens.

This work can also help to inform a future Local Nature Recovery Strategy in identifying valuable sites, sustainable land management and how the loss and/or fragmentation of existing habitats should be avoided as much as possible. The creation of bigger, better and joined-up habitats will be beneficial to wildlife, contributing towards the local plan’s objective of doubling nature. The creation of large networks will also support ecological resilience to predicted future impacts from climate change and are likely to overlap with net gains in flood risk management.

We recommend this policy also acknowledge the significance of invasive non-native species (INNS) and their impacts on wildlife and the environment. INNS are considered one of the top five threats to the natural environment. They can impact on wildlife, flood risk, water quality and recreation. Costs to the economy are estimated at £1.8 billion per year. Prevention through adopting biosecurity measures can help to reduce the spread and impacts of INNS.

BG/GI: Green infrastructure
We support the policy direction which will require all development to include green infrastructure, and protect/enhance water environments. We welcome the list of green infrastructure initiatives on page 8 173/174 which includes revitalising the chalk stream network and references the River Cam. It’s positive that developments will be expected to help deliver or contribute towards these to enhance the existing green infrastructure network.

In addition, we consider ‘connectivity’ as a key component of this policy. As noted in the Sustainability Appraisal (Non-Technical Summary p. 15) fragmentation and erosion of habitats can be detrimental to wildlife. Existing and new habitats and greenspaces should be retained and enhanced, in connection with existing habitats and the wider countryside, establishing a coherent ecological network, as per the NPPF. We support the references to ‘providing links’ and connecting to the wider ecological network as part of this policy, as this will be invaluable to both green infrastructure provision and nature recovery.

Existing areas of habitat and green spaces within proposed development footprints should be protected and incorporated within landscape designs where possible. As well as protecting existing areas of habitat, mitigation and environmental enhancements can be delivered through appropriate design that includes creation of new habitats and green spaces. New habitats should be representative of and complement the local landscape character, whilst being linked to existing features and the wider countryside, creating joined-up, resilient ecological networks

BG/RC: River corridors
We support the inclusion of a policy to manage development that has an impact on river corridors and proposes to protect, enhance and restore natural features, supporting re-naturalisation. This is particularly important for Cambridge due to the presence of chalk streams and the role rivers and their associated floodplains play in managing flood risk and provision of habitats. The proposed policy direction includes ‘ensure that the location, scale and design of development, protects and enhances the character’ and we recommend this includes the provision of appropriate setback of developments from rivers to provide sufficient space for flood waters as well as safeguarding the integrity of the river banks and the development itself. Rivers unless they have been artificially straightened move through their landscapes through natural processes of erosion and deposition. Although river migration occurs over long time periods, developments should be set back generously to account for this alongside climate change. Natural flood management also has the potential to deliver multiple benefits. Tall buildings can have an adverse effect if located too close to a watercourse by introducing overshadowing impacts and artificial lighting which disrupts natural diurnal rhythms of wildlife such as bats.

Wellbeing and inclusion – general comments
We recommend reviewing the document The State of the Environment: Health, People and the Environment (2020).This report, prepared by the Environment Agency, highlights the substantial body of evidence indicating the physical and mental health benefits of spending time in the natural environment. Access to the natural environment is not equally distributed, those living in deprived areas often have poorer quality environments with less accessible green and blue space. The GC Local Plan presents an opportunity to level-up communities, tackling this green inequality at scale and improving the health and wellbeing of those living and working in the GC area, by creating and contributing to healthier, greener, and more accessible environments. This must, however, be achieved in balance with the need to protect the environment, by providing appropriate wildlife refuges from human disruption and interference.

WS/HS: Pollution, health and safety
We would welcome a policy that details how land contamination should be considered, ensuring the land is suitable for the end use but also ensuring that water quality of the underlying aquifers is protected.

There are some plans and strategies that will be relevant to inform this policy. In 2018 the Government committed through the 25 Year Environment Plan to ‘achieve clean air’ and to ‘minimise waste, reuse materials as much as we can and manage materials at the end of their life to minimise the impact on the environment’. The State of the Environment: Health, People and the Environment (2020) highlights the extent of the threat that air quality poses to health in the UK, shortening tens of thousands of lives each year. Analysis also shows that areas of higher deprivation and those with high proportions of ethnic minorities are disproportionately affected by high levels of air pollution. Growth plans provide the opportunity to address these inequalities by improving the quality of the environment and strategically planning the location of land use types.

We welcome that the policy will provide protection to and from hazardous installations. However, Waste management facilities also have the potential to pollute the environment, cause nuisance or amenity issues through dust and particulate emissions to air, release to ground and surface water, and to leave a legacy of contaminated land. Studies have found that more deprived populations are more likely to be living closer to waste sites, and can therefore at times be subject to greater impacts such as noise, litter, dust, odours, or increased vehicular traffic. Strategic planning of waste and resource use provides the opportunity to address this issue.

H/RC: Residential caravans
This policy will set out the criteria to be used when considering proposals for new residential caravan sites. Annex C ‘Flood risk vulnerability classification’ of the National Planning Policy Framework (NPPF) classifies caravans, mobile homes and park homes intended for permanent residential use as highly vulnerable. Permanent caravans, mobile homes and park homes if located adjacent to rivers are at significant risk from being inundated very quickly from floodwaters, without sufficient warning or adequate means of escape. There are additional dangers from the potential for floating caravans (if they become untethered), cars and objects/debris becoming trapped beneath the caravans will increase the risk by displacing floodwater elsewhere.

Page 295 states that an accommodation needs assessment is currently being developed. The Sequential Test (paragraph 161 of the NPPF) should also be applied to the accommodation needs assessment to avoid where possible locating accommodation sites in areas at risk of flooding. This should be informed by the Level 1 and where necessary a Level 2 SFRA. We recommend given the high vulnerability of this type of accommodation that flood risk is a key consideration within the policy criteria.

H/GT: Gypsy and Traveller and Travelling Show People sites
The proposed policy direction includes ‘Sites are capable of providing an appropriate environment for residents in terms of health, safety and living conditions.’ Similar to our comments to Policy H/GT above, Annex C ‘Flood risk vulnerability classification’ of the NPPF classifies ‘caravans, mobile homes and park homes intended for permanent residential use’ as highly vulnerable. Sites used for holiday or short let caravans and camping (subject to a specific warning and evacuation plan) are classified as more vulnerable. We recommend given the higher vulnerability of this type of accommodation that flood risk is a key consideration within the policy criteria.

Page 298 states that a joint accommodation needs assessment is currently being developed. The Sequential Test (paragraph 161 of the NPPF) should also be applied to the accommodation needs assessment to avoid where possible locating accommodation sites in areas at risk of flooding. This should be informed by the Level 1 and where necessary a Level 2 SFRA.

The existing site at Fen Road continues to be a source of ongoing local water quality and environmental health problems due to inadequate foul drainage provision. There have been a number of reports of foul sewage from the site discharging into the River Cam, causing chronic on-going pollution. Water quality and ensuring appropriate drainage infrastructure is also an important consideration for these sites, both in terms of protecting the environment and safeguarding the health of the site occupiers. Policy H/23 ‘Design of Gypsy and Traveller Sites and Travelling Showpeople Sites’ in the South Cambridgeshire Local Plan 2018 provides an example of this, with the following wording: d. All necessary utilities can be provided on the site including mains water, electricity supply, drainage, sanitation and provision for the screened storage and collection of refuse, including recyclable materials;” Policy H/GT should include provision for mains foul drainage and protection of water quality as part of the policy criteria.

Infrastructure – general comments
Infrastructure and connectivity improvements, must be achieved in balance with the need to protect natural spaces, providing both accessibility and retaining restricted access refuges for wildlife. There is the opportunity to achieve both if, for example, cycle and pedestrian networks are considered strategically and systematically alongside green infrastructure and natural capital networks. A holistic approach to connectivity and infrastructure should be adopted, considering the multifunctional possibilities that provision of new transport and utilities infrastructure provide. For example, by integrating new road or rail schemes with flood resilience measures, energy generation, and green infrastructure enhancements.

I/SI: Safeguarding important infrastructure
We welcome the intention to work with infrastructure providers to consider whether planned strategic infrastructure or future land should be safeguarded. This should also include land for flood storage and flood risk infrastructure which is likely to include river corridors. Managing flood risk both now and in the future will require the plan taking a pro-active approach taking into account climate change. Your SFRA evidence base can inform this identification for safeguarding. The functional floodplain (Flood Zone 3b) is a zone comprising land where water has to flow or be stored in times of flood, identified in SFRAs and deemed to be the most at risk of flooding from rivers or sea. The SFRA should also gather information on flood risk management projects. The GOSIS (formerly Great Ouse Storage and Conveyance study) will assess how flood risk within the catchment can be managed now and into the future, giving a high-level evaluation of the costs of benefits of providing large storage volumes in the catchment. The GOSIS project will look for areas for flood risk management and draft outputs from this likely to be available towards the end of GC Local Plan process. There is also the Girton Flood Alleviation Scheme (Washpit Brook catchment) and flood risk management options at Oakington Brook (the latter referenced in our comments to Policy

As mentioned for Policy CC/FM, although a sequential approach has been considered there many sites proposed on the fringes of Flood Zones 2 and 3. This reduces and potentially eliminates future flood storage options for adapting to climate change. It’s important the L2 SFRA assesses these sites for their deliverability but also a broad perspective is taken to planning for flood risk both now and in the future. Creating extra flood storage to allow space for flood waters will be a vital component of that plan. We’d also expect safeguarding to include what is required for water infrastructure more broadly (water supply and waste) and green infrastructure/biodiversity.

I/ID: Infrastructure and delivery
We support the policy direction to propose to only permit development if there is, or will be, sufficient infrastructure capacity to support and meet all the requirements arising from the new development. The developer certainly has a role in this, beneath a robust and deliverable strategic framework led by the Council and other strategic infrastructure providers (informed by evidence).

As noted for Policy S/DS, we support the idea of development limited to levels that can be supported by a sustainable water supply (phased delivery) until the time the strategic infrastructure is in place. It is important that development is sustainable and the environment is protected throughout the process of infrastructure planning.

Infrastructure
Water. The issue of water is also partially addressed in 3.3.
On page 41, Policy S/DS: Development strategy states that “Water Resources East is currently preparing its Water Management Plan for the region to cover the period to 2050, expected to be published for consultation in 2022. It is understood that this will include planning for significant new infrastructure in the form of a new Fenland reservoir, alongside other measures, to provide water supply that is designed to address both environmental and growth needs. However, on current timelines, this will only be available to supply water from the mid 2030’s.”
I therefore welcome the intention to scale back developments until the fundamental issue of supply is resolved. I am sure that residents would not wish to be subjected to water shortages as a consequence of foreseeable actions.
It is understandable that those responsible for the supply of water to the region may have underestimated the rapid expansion of Greater Cambridge resulting in potential delays to developments of national importance. I would therefore urge Greater Cambridge Planning to enter into discussion with government at the highest level to seek means to enable Water Resources East to bring forward the timelines for their infrastructure project to mesh with timescales in the Greater Cambridge Local Plan.
I also note the intention to reduce the allowance of water for new developments from 110 to 80 litres/person/day and am concerned by any policy that seeks to limit the availability of water, which is a basic human need. Our planet may be under stress, but it is not going to run out of water soon – the issue is one of logistics and not shortage. This is a lazy solution that unfairly passes the buck to the consumer.
Whilst I fully accept the need to respond to climate change, proposals should be proportionate and minimise inconvenience. Whilst grey water may be a partial alternative, I question the wisdom of reducing living standards for the younger generation – people have enjoyed a relaxing bath, which relieves stress and can be good for mental health since Roman times. But, with a typical bath using 80 litres of water, new properties will simply be designed without baths – this is not progress…
There is a far more satisfactory answer. Industry figures show that, on average, 112 litres per property are lost through leakage every day. So, since leakage dwarfs the proposed savings that are required, surely on the principle of polluter pays, water companies should be required to repair their leaks? And, if that is not possible, then we may well conclude that the development is not in a suitable area and pressures from government must be resisted to build on the site.
In relation to electricity, Policy I/IE: Energy infrastructure masterplanning is key.
I note and welcome that work has been carried out to assess electricity grid capacity and that it concludes it would be necessary to triple capacity to support the development already planned in the area and electrification of transport. However, I have worked through this informally with the Director of a company that builds medical premises, and our initial calculations suggest that this could be a substantial underestimate. In fact, Greater Cambridge may need to multiply capacity by a factor of ten over the period of the Plan. I will work through our calculations again, setting out the steps and assumptions in more detail and will forward them once this is complete. Meanwhile:
· Based on data from WhatCar and taking the Hyundai Kona Electric 39kWh as “typical” with a range of 158 miles, I arrive at a typical annual use of 2,500kWh. With an average of 1.2 cars per household, this rises to 3,000kWh. This will effectively double electricity consumption for the average household.
· Now allow for domestic gas conversion to electricity. The calculations are complex, but have the potential to result in a 250% increase of electricity use.
· Cambridge is projected to grow by almost 50% over the time of the plan.
· The compound growth over the period is of the order of a factor of ten – and ignores the industrial and commercial use of energy and future growth beyond 2041...
There are further worrying and substantial aspects that relate to the stability of supply (most people will re-charge electric cars overnight) and the capacity delivered to individual homes (a 60amp supply delivers 14.4kW so a 7kW charger, a 3kW oven, 2.2 kW dishwasher and 2.5 kW kettle would blow a fuse!).
2.4.3 In relation to transport, there is much sensible discussion regarding reduction of car travel through the use of better provision for cycling, walking and public transport. However, the effect on the disabled and immuno-compromised is totally ignored – and potentially threatens to create issues of disability discrimination. For those disabled who struggle with walking and cycling, getting to public transport may prove supremely difficult and, for the immuno-compromised, public transport (including taxis) is not a good option. More widely, the law of unintended consequences of removal of parking spaces has not been fully considered – as a simple example, many drivers prefer to park on a verge outside their own home, rather than walk 100 yards to a parking space in a side road.
2.4.4 Finally, no consideration has been given to transport infrastructure in the Queen Edith’s area, which will become inadequate once Marleigh, Cambridge East and Fulbourn are established, and significant numbers of residents have to travel to work at the southern campuses (CBC, Babraham and Genome).
Following the opening of the Babraham Park and Ride, Lime Kiln Road has become a highly dangerous road with often no more than 50cm available between passing cars, has no pavements and is full of blind corners. The road is hilly and with cyclists travelling uphill regularly create hazards when frustrated motorists attempt to overtake. During the summer, pedestrians from the Caravan site can regularly be found wandering along the road.
2.5 The disabled
Although references to the disabled “tick all the boxes” in the first proposals, they are not expanded on at any point. This suggests that they will come in as an afterthought to any development. I propose that you include a separate section in the Plan that addresses the needs of the disabled across all sectors and that, before the Plan is approved, it is audited by a disability action group.

We are pleased that many of our comments at the Issues and Options stage, in our letter dated 24 February 2020 (ref. 304246), are reflected in the First Proposals Plan, helping to strengthen the Plan’s approach to the ‘big themes’ including climate change, biodiversity and green spaces, wellbeing and social inclusion. Natural England supports the general thrust of the Plan in directing development to where it will have least environmental impact and provide opportunities for enhancements.

Natural England’s previous advice highlighted the need for the Plan to address uncertainties relating to water resources and infrastructure needed to support new growth, in light of evidence that current levels of abstraction are already damaging the natural environment. We also signalled the need for the establishment of a strategic green infrastructure network that is resilient to the scale of proposed Plan development, capable of meeting people’s needs and addressing adverse impacts to the natural environment. We therefore welcome that the First Proposals Plan recognises the challenges in identifying long-term and interim solutions to the current water resource crisis to enable sustainable development without further detriment to the natural environment. We support the Plan’s progress, through the Green Infrastructure Recommendations (LUC, September 2021), in presenting opportunities for the Plan to deliver /contribute towards delivery of strategic green infrastructure.

Notwithstanding the above, Natural England believes significant additional work is required through the next stages of Plan preparation to progress these ‘solutions’ and demonstrate that development can be delivered sustainably. We have major concerns with the scale of proposed Plan development, and the 2041 timeframe for delivery, given the damage already being inflicted on the natural environment and the lengthy lead-in time for identification and delivery of measures to address the water resource issue and to implement strategic green infrastructure. Some of this Plan development is already progressing, through the adopted strategy, prior to solutions being identified and implemented; the natural environment is already being impacted. The Plan should consider how these impacts and spiralling environmental deterioration can be retrospectively

mitigated.

The section on ‘Ensuring a Deliverable Plan – Water Supply’ recognises the challenge relating to water resources; however, the Councils need to act urgently, in collaboration with relevant stakeholders, to identify strategic and interim water resource/infrastructure solutions to ensure any level of proposed development is delivered sustainably. There are currently no measures in place to mitigate the adverse effects of current development on the natural environment i.e., more water is being abstracted from the aquifer to serve this development, depleting groundwater resources and causing further declines in the condition of designated sites and supporting habitat.

Potential solutions to address Greater Cambridge’s green infrastructure deficit, and the recreational pressure effects of development, lie within the Green Infrastructure Initiatives identified in LUC’s Opportunity Mapping Recommendations Report. Natural England fully supports the Initiatives identified; however, these aspirational areas must be progressed into real projects that are happening on the ground by the time the Plan is adopted. Robust Plan policy requirements should secure funding for the delivery and long-term management of these projects from all major development.

We have provided additional comments on the Plan’s key themes and policies below; however, reference should be made to the detailed advice provided in our response to the Issues and Options consultation.

Vision and aims
We support the Plan vision and aims for decreases in our climate impacts and increase in quality of life for communities, minimising carbon emissions and reliance on the private car, increases in nature, wildlife, greenspaces and safeguarding landscapes focusing on what is unique to Greater Cambridge embracing bold new approaches.

Natural England strongly recommends that the vision should advocate a more holistic approach to securing multi-functional benefits through the protection and enhancement of the natural environment. In accordance with paragraphs 17 and 109 of the National Planning Policy Framework (NPPF) the Plan should encourage multiple benefits from the use of land in urban and rural areas, recognising that land can deliver a wide range of ecosystem services required for sustainable development including climate change mitigation, flood management, improved water resources and water quality, biodiversity net gain, accessible high quality green infrastructure and associated health and wellbeing benefits, enhanced landscapes and soil resources.

The Plan should contribute to and enhance the natural and local environment by recognising the wider benefits of ecosystem services, considering a natural capital evidence approach and making strong links to the Nature Recovery Network and the Cambridge Nature Network. National Habitats Network mapping is available to view at www.magic.defra.gov.uk.

Development Strategy
The Plan will deliver around 44,400 new homes and provide for approximately 58,500 new jobs. We welcome that the new development strategy aims to meet our increased need for new homes in a way that minimises environmental impacts and improves the wellbeing of our communities.
The strategy proposes 19 additional sites for development, along with sites already allocated in the adopted 2018 Local Plans, along with associated infrastructure including green spaces.

We support proposals to direct development to where it has the least climate impact, where active and public transport is the natural choice, where green infrastructure can be delivered alongside new development, and where jobs, services and facilities can be located near to where people live. The vision includes creating new city neighbourhoods which have the critical mass of homes, jobs and services to create thriving communities, making best use of brownfield and safeguarded land and making the most of public transport links.

Natural England welcomes the use of evidence including the Employment Land and Economic Development Evidence Study and the Greater Cambridge Housing and Employment Relationships

Report to understand the relationship between future jobs and housing growth. We note that these studies found that planning for the standard method housing figure set by government would not support the number of jobs expected to arise between 2020 and 2041. Planning for this housing figure would risk increasing the amount of longer distance commuting into Greater Cambridge, with the resulting impacts on climate change and congestion. On this basis planning for a higher jobs figure and planning for government’s standard method local housing need figure have been rejected as reasonable alternatives.

We note that high-level consideration has been given to the potential impacts of COVID-19 on the economy of Greater Cambridge, to inform this First Proposals consultation. We support the proposal to gather evidence to consider the potential longer-term quantitative impacts of COVID- 19 prior to the Draft Plan stage to understand any implications for the objectively assessed need for jobs and homes for the plan.

Natural England has no objection in principle to the proposed Plan development strategy; however, this is subject to: 1) the identification of strategic water supply solutions and / or interim measures; and 2) development of deliverable strategic GI initiatives and developer requirements and funding mechanisms being secured through the Plan.

Policy S/DS: Development strategy
Figure 6: Map shows proposed sites to be included in the Plan including existing planning permissions alongside a limited number of new sites in the most sustainable locations. We welcome that the sustainability merits, opportunities and constraints for each of the nine potential strategy choices have been considered through the Sustainability Appraisal. Alongside considering the best locations for new homes and jobs, consideration has also been given to the best locations to restore the area’s habitat networks and provide more green spaces for people providing health and wellbeing benefits. Natural England fully supports the identification of 14 Strategic Green Infrastructure Initiatives, through the Green Infrastructure evidence, to help achieve this. We welcome the approach to preparing the preferred development strategy / draft allocations and green infrastructure initiatives in parallel.

We support the general policy direction to focus development where it will have the least climate impact, where it can be aligned with active and public transport, opportunities for delivery of green infrastructure and where jobs, services and facilities can be located nearby whilst ensuring all necessary utilities can be provided in a sustainable way. We support the approach to using less land for development to reduce carbon emissions and allow more space for nature and wildlife.
The strategy focuses on opportunities to use brownfield land and opportunities created by proposed major new infrastructure.

We note that delivery of the adopted strategy is progressing well with development permitted/underway /completed at the edge of Cambridge sites and new settlement sites including Northstowe and Waterbeach New Town. Natural England is aware that these schemes are being delivered in the absence of adequate sustainable water supply infrastructure to serve the development without adverse impact to the natural environment including statutorily designated sites. Many of these schemes are also unlikely to deliver sufficient level of accessible high quality green infrastructure to meet the needs of new residents without adverse recreational pressure impacts to the existing ecological network including statutorily designated sites. These issues need to be addressed urgently through further stages of Plan preparation as discussed in our advice above and below.

Ensuring a deliverable plan – water supply
We welcome the Councils’ recognition that water supply is a significant issue for the deliverability of the Local Plan and we fully support preparation of the Integrated Water Management Study: Outline Water Cycle (WCS) by Stantec (August 2021) to address this. The WCS has identified the need for new strategic water supply infrastructure, such as a new fens reservoir, to provide for longer term needs, and to protect the integrity of the chalk aquifer south of Cambridge, in addition to a range of interim demand management measures. The draft Sustainability Appraisal also identifies significant environmental impacts if the issue is not resolved. This is a major concern for

Natural England in light of proposed growth levels and the damaging effects that groundwater abstraction is already having on the natural environment including water-dependent designated sites and important chalk stream habitats. Natural England has provided its detailed advice on this matter, and highlighted the statutorily designated sites potentially affected, in our response to the consultation on the WCS. These ‘Designated Sites of Concern’ are listed in Appendix B of the August 2021 report.

We are aware that Water Resources East is currently preparing its Water Management Plan for the region and that this will help to identify long-term measures to address the issue. However, these strategic measures, including a new fens reservoir, are unlikely to be available until the 2030’s hence interim measures are required to enable some level of sustainable growth. We welcome the suggestion of including Plan policies to phase delivery of development that can be supported by a sustainable water supply until new strategic infrastructure is in place; however, it will need to be clearly demonstrated that interim solutions are sustainable and will not cause further environmental decline. The risk is that it may not be possible to demonstrate delivery of the full objectively assessed needs within the plan period.

Natural England appreciates that pressure on water supplies is a regional issue. We share the Councils’ aspirations that the water industry, supported by government, will set out its intentions for positively addressing this key infrastructure issue at an early point in the ongoing plan making process, to provide confidence that adequate water supply will be available to support delivery of the preferred options allocations, before the next stage of a full draft Local Plan. In our view the Councils need to act urgently, in collaboration with relevant stakeholders, to identify strategic and interim water resource/infrastructure solutions, including demand management measures, to ensure any level of proposed development is delivered sustainably.

We have serious concerns that Plan development is already being progressed, through the adopted strategy, without sustainable water supply measures in place. More water will be abstracted from the aquifer to serve this development, depleting groundwater resources and causing further declines in the condition of designated sites and supporting habitat. The Plan will need to consider the impacts of this development and identify measures to address adverse environmental impact.

Natural England fully supports the concerns raised by the Environment Agency, as lead authority on this matter, including the high degree of uncertainty as to whether sufficient sustainable water supplies can be provided for the proposed growth over the plan period without further detriment to the natural environment. Further development of the WCS, informed by evidence from regional and water company water resource plans, will need to demonstrate that appropriate deliverable mitigation measures can support sustainable growth until new strategic water supply infrastructure becomes operational. We agree with the Environment Agency that it in the face of current challenges it may be appropriate to consider an extended timeframe for delivery of Plan development to limit further environmental degradation until new strategic measures become available. This would allow further time for the identification of truly sustainable options that build in resilience to climate change and robust mitigation and monitoring measures to address impacts to the natural environment and restore habitat condition.

Duty to Cooperate
Natural England welcomes consideration of how the Plan fits with other plans and strategies including cross boundary projects such as the Ox Cam Arc. We support recognition of the Plan to be prepared within a wider regional context noting the Councils’ legal duty to cooperate with key stakeholders and surrounding areas of cross boundary issues. We agree that the development of a clear and positive vision for the future of the Greater Cambridge area can help to shape the proposals for the Ox Cam Arc, noting that the outcome of the Oxford-Cambridge framework is currently awaited.

We particularly support the Councils’ recognition that the water supply challenge discussed above is a serious issue to be resolved.

Natural England will be pleased to engage with the Councils in the preparation and development of a draft Statement of Common Ground.

Transport Strategy
Natural England welcomes that the proposed strategy is heavily informed by the location of existing and committed public transport schemes. We support the use of transport modelling to understand whether additional infrastructure and policies are required to address the transport impacts of the preferred development strategy.

Transport policies should include requirements for projects to undertake robust ecological impact assessment and application of the ecological mitigation hierarchy.

Site allocation policies
Proposed site allocation policies are described through sections 2.2 – 2.5. Natural England has no objection in principle to the existing and new allocations, areas of major change or opportunity areas being taken forward for development. However, this is subject to:
• identification of strategic water supply infrastructure and/or feasible interim solutions to demonstrate that development can be delivered sustainably and without adverse impact to the natural environment;
• establishment of a framework and robust plan policies to deliver the 14 Strategic Green Infrastructure initiatives ahead of development, to meet development needs and to address the effects of recreational pressure on sensitive sites and habitats.

The site allocation policies will need to include robust requirements to secure delivery of biodiversity net gain and on-site accessible green infrastructure to meet people’s need and to contribute towards the Plan’s 20% BNG targets and delivery of the Nature Recovery Network / Cambridge Nature Network. Our advice is that major allocation policies should set a framework for development to maximum opportunities for environmental gains.

Climate Change
We welcome the proposed policies relating to net zero carbon and water efficiency, designing for climate change, flooding and integrated water management, renewable energy projects, reducing waste and supporting land-based carbon sequestration. We particularly support the proposed requirement for residential developments to be designed to achieve a standard of 80 litres/person/ day; however, we support the Environment Agency’s concerns as to whether the Plan is likely to achieve the reductions in demand required to support sustainable growth. As indicated above the WCS will need to demonstrate how water, to meet growth needs, will be supplied sustainably without adverse impact to the natural environment.

Proposed requirements for developments to provide integrated water management, including sustainable drainage systems (SuDS) where possible and for SuDS and green /brown roofs to provide multiple benefits (including biodiversity and amenity) are welcomed.

We support requirements for renewable energy projects to consider impacts on biodiversity, geodiversity, landscape and water quality.

Natural England welcomes a proposed policy to support the creation of land and habitats that play a role as carbon sinks and protect existing carbon sinks from development, particularly peatlands such as those remaining in the north of South Cambridgeshire district. We welcome recognition of the importance of peatlands as a carbon store and the role of other habitats such as woodlands and grasslands, noting loss and degradation of natural habitats results in the direct loss of carbon stored within them.

As indicated above we recommend that the Plan takes a more holistic approach to securing multi- functional benefits for climate change, flood management, water resources and water quality through the protection and enhancement of the natural environment. Natural solutions can achieve significant additional benefits for biodiversity, green infrastructure and associated health and wellbeing benefits, enhanced landscapes and soil resources.

Biodiversity and green spaces
We strongly support the proposed biodiversity and green spaces policies and the inclusion of Figure 53 depicting the existing Greater Cambridge green infrastructure network including designated sites.

We welcome that these policies will help to deliver the aims of the Ox Cam Arc of doubling the area of land managed primarily for nature and to deliver a minimum 20% biodiversity net gain on development sites, beyond the mandatory 10% biodiversity net gain requirements of the Environment Act 2021. We agree that Greater Cambridge has a relatively low level of designated sites and priority habitats, highlighting the need for development to deliver net gains beyond the 10% proposed nationally, hence we are fully supportive of minimum 20% BNG ambitions. Our advice is that the Councils, working with key partners, should identify BNG opportunities through the next phases of Plan preparation. This should take the form of a BNG opportunities / requirements map building on the foundations of the Nature Recovery Network and the Cambridge Nature Network. National Habitats Network mapping is available to view at www.magic.defra.gov.uk.

The Councils should also set a landscape / GI framework for the Site Allocations to maximise opportunities for delivery of GI and BNG within the development sites.

BG/BG: Biodiversity and geodiversity
Natural England fully supports this policy and requirements for development to achieve a minimum 20% biodiversity net gain, delivered on site where possible and calculated using the Defra Metric
3.0 or its successor. Requirements for off-site measures to be consistent with the strategic aims of the Greater Cambridge green infrastructure network strategic initiatives are welcomed.

The policy should take a natural capital evidence approach and recognise the wider benefits of ecosystem services for climate change, flood risk management, green infrastructure and health and wellbeing, in addition to biodiversity. They main thrust of this policy should be the Plan’s contribution to the Nature Recovery Network / Cambridge Nature Network and the establishment of a framework for the development of a Local Nature Recovery Strategy.

We support proposed requirements for development to avoid adverse impact to site of biodiversity or geological importance and development to mitigate recreational pressure on statutorily designated sites, applying Natural England’s SSSI Impacts Risk Zones (IRZs). The Plan’s biodiversity policy should recognise the hierarchy of international, nationally and locally designated sites across Greater Cambridge. This should be accompanied by a map of the existing ecological network and enhancement opportunity areas to guide site allocations / development away from more sensitive areas and to identify opportunities for developers to deliver net biodiversity gain enhancements.

We welcome that the policy will seek wider environmental net gains. These should focus on measures to restore ecological networks, enhance ecological resilience and provide an overall increase in natural habitat and ecological features.

Reference should be made to the detailed advice provided in our response to the Issues and Options consultation with regard to protecting and enhancing biodiversity including designated sites, priority habitats, ecological networks and priority and/or legally protected species populations. This includes additional detailed advice on embedding biodiversity net gain into the Greater Cambridge Local Plan policies.

BG/GI: Green infrastructure
We welcome the comprehensive and thorough approach taken in developing the GI evidence base for the Greater Cambridge Local Plan, including the Opportunity Mapping and the identification of 14 Strategic GI initiatives. The multifunctional benefits of GI are fully recognised, as well as the links between GI provision and the delivery of other strategic policy areas including the wider natural environment, sustainable transport and social inclusion. These threads/links

should continue through future drafts to ensure the value of GI for people and the natural environment is fully reflected in the Local Plan.

The Strategic GI initiatives are comprehensive and capture a wide variety of GI opportunities within the 14 proposals; this range of GI elements and habitats will help to maximise benefits for people and nature through the strategic planning and delivery of GI across Greater Cambridge. We support the emphasis given to blue infrastructure in Strategic Initiatives 1 and 2 given the considerable pressures on Cambridgeshire’s chalk streams and aquifer from agriculture and development. The Chalk Stream Strategy Report1 recently published by CaBA identifies a number of recommendations to protect/restore chalk stream habitats, including those in areas of high population density such as Cambridge. This report may be a useful reference in planning and progressing strategic blue infrastructure initiatives as part of the Greater Cambridge Local Plan.

We support the proposed approach to have a distinct GI policy within the Local Plan, rather than a stand-alone SPD. As noted in the Topic Paper, we agree that the policy should require all developments to contribute towards GI and that it should be incorporated into design from an early stage and through all phases of development, with a longer-term plan in place for its management and maintenance. As well as a GI policy, Green Infrastructure should be integrated into other strategic policy areas and Local Plan themes where relevant. This will give weight to the multifunctional role of GI and demonstrate where it can contribute to policy delivery and outcomes (e.g., in climate change adaptation, supporting healthy communities etc). It will also support the role of GI in implementing other mechanisms and tools, such as Biodiversity Net Gain, and may help in targeting and prioritising opportunities for GI creation and enhancement.

In addition to securing GI within individual developments, the Local Plan should also provide a framework for proposals to contribute to / link up with the wider Strategic Initiatives, including the ‘dispersed initiatives’ 10-14 (e.g., ‘Expanding the Urban Forest’). Consideration should also be given to potential join-ups on cross-boundary projects and, in time, how the strategic GI network in Greater Cambridge may contribute to greenspace at the regional level (as one of the 5 Ox-Cam counties). There may also be overlaps with other initiatives, such as the Nature Recovery Network, where Cambridgeshire’s GI resource can make an important contribution (such as that highlighted in Strategic Initiative 3 for the Gog Magog Hills and Chalkland fringe).

We note from the Part 2 Recommendations Report that there are several points for further consideration, including the funding mechanisms required to ensure that all developments include GI and contribute towards the strategic initiatives. Funding mechanisms (e.g., developer contributions) should be embedded in policy where required and should be identified as early as possible to ensure that benefits are secured long-term. For example, the policies for major allocations will need to include specific requirements for the funding / delivery of the strategic GI ahead of the developments being occupied so that these are clear from the outset. The report presents a number of potential funding sources, including land use planning obligations (e.g., S106) agri-environment streams (such as ELMS) and any ad-hoc opportunities that may arise through partnership working. The increasing emphasis on nature-based solutions may also bring in new revenue streams to support strategic projects, given that many NBS will require a landscape scale / ‘ecosystem’ approach. The costings for the delivery of the GI and biodiversity aspects of the Local Plan could be included in the IDP so that the investment required to bring about delivery is clear and transparent from an early stage and factored into development proposals. Given the significant scale of the work required, consideration should also be given to how the land will be secured to deliver the GI initiatives, whether through direct purchase, lease or management agreements. A long-term approach to the management and maintenance of GI (ideally in perpetuity) also needs to be factored in from an early stage.

Alongside its value for natural capital and placemaking, green infrastructure provides alternative natural greenspaces that can help alleviate and buffer recreational pressures on protected sites. We welcome the recognition of the recreational pressure impacts across Greater Cambridge, and

1 1 Catchment Based Approach (October 2021) Chalk Stream Restoration Strategy: Main Report. See: New strategy launched to protect chalk streams - GOV.UK (www.gov.uk)

the Strategic Initiatives aimed at addressing these (e.g., the Coton corridor and multifunctional GI corridors, Strategic Initiatives 7-8). We support the development of clear policy requirements to address these significant pressures (as suggested in the Topic Paper).

Given the Local Plan’s strong emphasis on GI and the widespread benefits that it can achieve, we feel there is clear value in having a recognised GI standard in place. A standard would help to guide and inform GI planning and delivery and provide a consistent benchmark on quality across different scales/locations of development. It would also support the recommendation in the report for a GI-led design approach to new development. A standard could be supported by other documents, e.g., Local Design Guides, to ensure that nature is fully built into design through the provision of high-quality green infrastructure. Natural England is currently developing a Green Infrastructure Framework to set standards for green space and access to natural greenspaces, as well as a Design Guide and mapping data2 to support this work. We would encourage the use of these resources to guide and inform development of strategic Green Infrastructure and policies for Greater Cambridge. The Framework of GI Standards and products are due for launch in summer/autumn 2022, with a pre-release of the beta mapping and the principles of good green infrastructure in December 20213.

Natural England fully supports the proposed inclusion of policies to improve tree canopy cover, enhance river corridors and protect and enhance open spaces. We advise that robust policy requirements should be included to secure delivery of enhancements through development to ensure the achievement of multi-functional benefits for climate change, biodiversity, water quality, access. As indicated in our comments at the Issues and Options stage tree planting needs to be targeted in appropriate locations and considered in the context of wider plans for nature recovery. Consideration should be given to ecological impacts and the opportunities to create alternative habitats that could deliver better enhancements for people and wildlife, and store carbon effectively. Where woodland habitat creation is appropriate, consideration should be given to natural regeneration, and ‘rewilding’ for the economic and ecological benefits this can achieve.
Any tree planting should use native and local provenance tree species suitable for the location. Natural England advocates an approach which seeks to increase biodiversity and green infrastructure generally, not simply planting of trees, and protecting / enhancing soils, particularly peat soils.

For further advice and guidance on green infrastructure please refer to our comments at the Issues and Options consultation stage.

Wellbeing and inclusion
Natural England is fully supportive of the proposed policies including WS/HD: Creating healthy new developments. Our advice is that the policy should include strong links to the importance of adequate level and quality of accessible green infrastructure for people’s physical and mental health and wellbeing.

Great places
Natural England supports the proposed Great Places policies. We welcome the establishment of a Place and Design Quality Panel to conduct a site typologies study to understand, protect, utilise and enhance the valued characteristics of different areas in the plan, with the intention of using this information to raise design standards to ensure development reflects and enhances Cambridge’s distinctive landscape and townscape character.

We support Policy GP/LC Protection and enhancement of landscape character. Natural England is pleased to see that the Greater Cambridge landscape character assessments have been updated and will provide an up-to-date evidence base for the development of policy GP/LC. Existing retained policies form the South Cambridgeshire Local Plan NH/1, NH/2 and NH/13 and policy 8 of the Cambridge Local Plan should be reviewed and updated in the light of these updated landscape

2 See the GI Framework Mapping Portal: https://designatedsites.naturalengland.org.uk/GreenInfrastructure/Home.aspx 3 How Natural England’s Green Infrastructure Framework can help create better places to live - Natural England (blog.gov.uk)

character assessments to ensure they reflect the most recent baseline evidence.

Policy GP/LC seeks to identify, protect and enhance locally valued landscapes. Any locally designated landscapes, e.g., Areas of Greater Landscape Value, should be identified within the plan and given appropriate policy protection to protect and enhance them and to ensure that development reflects their distinctive character. It is not the role of Natural England to define locally valued landscapes – this is for LPAs and their communities. However, it should be noted that NE considers World Heritage Sites designated for their natural interest, local landscape designations and Inheritance Tax Exempt land to be locally valued. Therefore, these areas should be identified and included on policy maps showing locally designated landscapes along with any ‘Protected views’.

The Strategic Spatial Options Assessment appears to have considered a wide range of options based on up-to-date evidence on landscape and townscape character considerations. We support this approach which is useful in identifying and considering key landscape issues early in the Plan- making process, to feed into the Sustainability Appraisal. We note that the appraisal of the strategic spatial options is based on the interim draft findings of the emerging Landscape Character Assessment. We trust that the preliminary conclusions will be updated following completion of this work. The analysis also notes that recommendations are provided for strategic landscape mitigation and enhancement for each of the strategic spatial options. Natural England supports the proposal to identify specific mitigation as part of more detailed studies in locating and designing future development.

We are generally supportive of policies to protect and enhance the Cambridge Green Belt, achieve high quality development and establish high quality landscape and public realm.

Jobs
Natural England supports proposed policy J/AL: Protecting the best agricultural land. We welcome recognition of soil as a valuable resource and key element of the environmental ecosystem which requires protection, in accordance with paragraph 174 of the NPPF. We note that the protection of peat soils is addressed under the climate change theme discussed above.

Beyond the wider water resource / supply issue, discussed above, we have no substantive comments on the other proposed policies. However, policies will need to include appropriate requirements to ensure that all development avoids adverse impact to the natural environment and delivers net gains for biodiversity in accordance with the requirements of policy BG/BG: Biodiversity and geodiversity.

Homes
Beyond the wider water resource / supply issue we have no specific comments to make on these proposed policies subject to the inclusion of appropriate requirements to ensure that all development avoids adverse impact to the natural environment and delivers net gains for biodiversity in accordance with the requirements of policy BG/BG: Biodiversity and geodiversity. Residential development should also contribute towards delivery of the Strategic GI Initiatives.

Infrastructure
Natural England supports proposed policy I/ST: Sustainable transport and connectivity for the environmental and health benefits this could achieve including reduced emissions, air quality and climate change benefits.

We have no substantive comments on the other proposed policies subject to the inclusion of appropriate requirements to ensure that all development avoids adverse impact to the natural environment and delivers net gains for biodiversity in accordance with the requirements of policy BG/BG: Biodiversity and geodiversity.

Habitats Regulations Assessment (HRA)
Natural England supports preparation of the HRA Report by LUC (August 2021). We welcome that this incorporates a screening assessment and Appropriate Assessment. The Screening stage

identifies likely significant effects on European sites, either alone or in combination with other policies and proposals, for several plan policies. These include:
• Physical damage and loss (offsite) – in relation to Eversden and Wimpole Woods SAC.
• Non-physical disturbance (offsite) – in relation to Eversden and Wimpole Woods SAC.
• Recreation – in relation to Wicken Fen Ramsar SAC and Fenland SAC.
• Water Quantity and Quality – in relation to Ouse Washes SAC, SPA and Ramsar site, Wicken Fen Ramsar site, Chippenham Fen Ramsar site, Fenland SAC and Portholme SAC.
The Appropriate Assessment concludes no adverse effect on site integrity as follows: Eversden and Wimpole Woods SAC
Subject to the following safeguards and mitigation measures being implemented:
• Completion of bat surveys for site allocations identified with moderate or high potential to support barbastelle to determine the ecological value of these sites in relation to this bat species and to inform specific mitigation proposals.
• There is a commitment in the plan that proposed development will avoid key habitat features likely to be used by this species and to create and enhance suitable habitat for this species.
• It is also recommended that policy wording in the plan is strengthened to include specific inclusion of the safeguard measures detailed above and that Policy BG/BG Biodiversity and geodiversity is strengthened to include specific reference that mitigation provided should be suitable to the level of protection afforded to designated sites.

Wicken Fen Ramsar site and Fenland SAC
The Appropriate Assessment concludes no adverse effect on integrity as a result of increased recreational pressure provided that the following safeguards and mitigation measures are required by the plan and successfully implemented:
• A commitment in the plan to ensure that development within 20km of the Ramsar site and SAC to provide sufficient suitable alternative natural greenspace in line with advice from Natural England and that there should be specific detail on the policy on the appropriate quantity and quality of open spaces and how delivery and management in perpetuity will be secured.

The Appropriate Assessment is currently unable to conclude no adverse effect on the integrity of the Ouse Washes SAC, SPA and Ramsar, Wicken Fen Ramsar site, Chippenham Fen Ramsar site, Fenland SAC and Portholme SAC, with regard to water quantity and quality, pending the provision of further evidence through the Greater Cambridge IWMS and the WRE IWMP.

We welcome that the HRA has provided a detailed consideration of air quality impacts, associated with Plan development, for the relevant European sites. This is based on best practice Highways England Design Manual for Road and Bridges (DMRB) LA 105 Air quality guidance and considers the potential for traffic-related emissions on the affected road network based on traffic modelling data, in line with the advice provided by Natural England at the Issues and Options stage. Whilst the assessment has ruled out likely significant effects on all relevant European sites Natural England has been unable to carry out a detailed review of this information and will provide comments at the next stage of Plan consultation.

Please note that Natural England is reviewing the Impact Risk Zone (IRZ) for Eversden and Wimpole Woods SAC to take into account the findings of emerging SAC barbastelle tracking surveys being undertaken for major development schemes. It will also take into consideration the availability of suitable foraging resource which is considered to be quite scarce in the local area. In the meantime, until the IRZ is formally amended, and accompanying guidance prepared, we welcome application of a precautionary 20km buffer zone for SAC barbastelles in line with Natural England’s current local guidance.

Natural England is generally supportive of the interim findings of the HRA and will provide further

advice as the HRA is updated in line with the development of Plan policies and further evidence.

Sustainability Appraisal
Through the Sustainability Appraisal (LUC, October 2021) the preferred policy approaches for the Local Plan have been subject to appraisal against the SA objectives. A range of reasonable alternative options has also been assessed, including alternatives to the preferred policy approaches, Strategic Spatial Options and site options. We welcome that the findings of the HRA will be incorporated into the SA and will provide further insight into biodiversity impacts specifically at designated sites, presenting the opportunity to limit adverse impacts at these locations.

We support recognition of the over-abstraction of water in this region as a serious concern. We welcome acknowledgement that action is required now to ensure the availability of water for future uses without detrimental impact on the environment. Natural England agrees that water resource availability and water quality are inter-related and that these are likely to be exacerbated by the effects of climate change.

The new Local Plan presents the opportunity for new development to come forward at the most appropriate locations in order to avoid detrimental impacts on biodiversity assets. However, we support recognition of potential risks to the ecological network including statutorily designated sites, through degradation and other impacts associated with development.

We agree that the new Local Plan provides the opportunity to promote biodiversity gain and to improve the overall ecological network. Natural England also agrees that opportunities identified through the Green Infrastructure Study (2020) could support delivery of Natural England's Habitat Network nearby opportunity zones and support pollinator corridors. Robust plan policies will need to be developed to secure delivery of these enhancements through all relevant development.

The report concludes that overall, the proposed direction of the Local Plan performs well in sustainability terms with a strong focus on providing an appropriate amount of development and policies focused on minimising carbon emissions, particularly through minimising the need to travel, using land efficiently and making the most of existing and planned sustainable transport links. Natural England suggests this is a premature conclusion in the current absence of strategic water supply infrastructure and sustainable interim measures. Development through the adopted strategy is already being progress without these measures in place. Further development of the Green Infrastructure Initiatives is also required to ensure adequate GI to meet development needs and to alleviate recreational pressures on some of our most sensitive sites habitats. Robust plan policies, to secure timely delivery of this strategic green infrastructure, will be required to demonstrate the Plan’s sustainability.

We generally welcome the policy recommendations presented within Chapter 5 of the SA report including reference to the mitigation hierarchy within Policy BG/BG: Biodiversity and geodiversity and stronger commitments to protect and enhance biodiversity within this and the site allocation policies. However, in our view SA recommendations should focus on the urgent requirement for the identification of strategic and interim water resource/infrastructure solutions and further work to progress the GI Initiatives into real projects.

Natural England will provide further advice as the SA is updated in line with the development of Plan policies and further evidence.

We hope our comments are helpful. For any queries relating to the specific advice in this letter only please contact Janet Nuttall on […]. For any new consultations, or to provide further information on this consultation please send your correspondences to consultations@naturalengland.org.uk.
