Green Belt & countryside

The human version (we wrote this, not the council)This allocation covers Terriers Farm, a 24-hectare site on the northern edge of High Wycombe, for an assumed 410 homes, which already have planning permission subject to legal agreements. The site must include a sport and recreation hub extending Hazlemere Recreation Ground, helping keep the development physically separate from Hazlemere. Development should retain the main north-south hedgerow, field boundaries, the pond and a wildlife corridor towards King's Wood, and contribute financially to the new primary school planned at Gomm Valley. Road, junction, bus stop and footpath improvements are also required.

The human version (we wrote this, not the council)This allocation supports an assumed 100 homes at Abbey Barn North, High Wycombe, designed to fit the site's bowl-shaped, sloping landscape. Conventional houses with gardens are not considered appropriate; innovative homes set within the landscape are required instead. The plans require a buffer of at least 15 metres to Deangarden Wood, retention of chalk grassland, new footpaths, cycle and bridleway links, and contributions to road, bus and path improvements. A development brief has already been prepared for the site.

The human version (we wrote this, not the council)This policy sets when and how much affordable housing developers must provide. In Designated Rural Areas it applies to schemes of 2 or more homes or sites of 0.5 hectares or more; everywhere else it applies at 10 or more homes or 0.5 hectares. In Zone 1, at least 50% affordable housing is required on Green Belt or Cotswolds National Landscape sites and 40% elsewhere. In Zone 2 the figures are 40% and 30%. Where demolition is involved, the thresholds apply to the net increase in homes.

The human version (we wrote this, not the council)This section sets out the detail and justification for the affordable housing requirements. Evidence identifies a need for 1,237 affordable homes a year across South Warwickshire, about 56% of the total housing need of 2,197 homes a year. On schemes of 10 or more homes, affordable housing should normally be built on site, while smaller schemes in rural areas pay a financial contribution instead. Some development types, such as holiday lets, mobile homes and residential annexes, are exempt. Affordable homes will be secured in perpetuity through Section 106 legal agreements, and requirements are subject to viability.

The human version (we wrote this, not the council)This section gives the detailed rules and reasoning for rural exception sites. Housing need must be evidenced by a proper survey of residents, normally valid for five years, with future occupiers showing a strong local connection through birth, residence, work or family. Some market housing may be allowed to make a scheme viable or meet a surveyed local need, but never more than 50% of the homes. A Section 106 agreement will secure occupancy, tenure and long-term management. The policy exists because high prices and restricted supply make affordable housing especially hard to deliver in rural areas.

The human version (we wrote this, not the council)This allocation covers land at RAF Halton, an eighty-two hectare military base near Wendover due to close in 2030. It is allocated for an assumed 1,000 homes, a primary school and a new local centre reusing St George's Church. Half the site must be green infrastructure, with parkland, play space and links to Wendover Woods. Historic features, including the Registered Park and Garden and listed barracks, would be restored or converted. New roads, junction upgrades and mitigation for the Chilterns Beechwoods protected area are also required.

The human version (we wrote this, not the council)This policy supports self-build and custom-build housing through several routes. On large developments of 500 or more homes, 2% of dwellings must be provided as serviced self-build plots unless the councils' register shows lower demand, with plots offered at a range of costs, sizes and types and an average density of 25 homes per hectare. Standalone schemes are also supported within settlement boundaries, on suitable sites next to larger settlements outside the Green Belt or Cotswolds National Landscape, or adjoining settlements where a local community need is evidenced.

The human version (we wrote this, not the council)This allocation proposes an assumed 355 homes on 8.93 hectares north of Reynolds Mead, Cheddington. The site is close to the Mentmore Conservation Area and Registered Park and Garden, so a heritage assessment and careful design are required. A substantial buffer must protect the wood pasture priority habitat next to the northern boundary, and landscaping must soften views from the surrounding countryside. Contributions are required to shared infrastructure including the Horton Bypass and a new railway bridge, and protected area mitigation must be in place first.

The human version (we wrote this, not the council)This allocation creates a new Key Employment Area as a northern expansion of the Princes Estate, an established business area in Princes Risborough. It provides approximately 4 hectares of land for offices, industrial and storage uses, and housing is ruled out because it would undermine the employment role. Designs must limit visual impact on the Chilterns National Landscape, the Ridgeway National Trail and the Horsenden Conservation Area. Financial contributions are required towards walking and cycling links between Princes Risborough, Longwick and Chinnor.

The human version (we wrote this, not the council)This allocation designates approximately twelve hectares of land north of Lower Icknield Way, Princes Risborough, as a new Key Employment Area, of which 9.6 hectares is expected to be developed for business, industrial and storage uses. The site is visible from the Chilterns National Landscape and the Ridgeway National Trail, so high-quality design and structural landscaping are required, including new hedgerow planting. Access would come from Lower Icknield Way, with contributions towards the Princes Risborough to Chinnor walking and cycling route.

The human version (we wrote this, not the council)This allocation provides 2.6 hectares of employment land behind Stokenchurch Business Park, near Junction 5 of the M40, for light industrial, general industrial and storage uses. The site lies within the Chilterns National Landscape, so proposals must take a landscape-led approach backed by a Landscape and Visual Impact Assessment. Development must connect properly to the existing business park so it works as one employment area. Its proximity to the Aston Rowant protected area, about five hundred metres away, means further habitat assessment is required.

The human version (we wrote this, not the council)This allocation supports Marlow Film Studios at Little Marlow as a film, high-end television and media production complex within the West of London Screen Cluster. The site already has planning permission following an appeal decided by the Secretary of State. Development must include improvements to the Westhorpe interchange, a new pedestrian and cycle bridge across the A404, and links to Marlow station and Bourne End. As the site sits in the Metropolitan Green Belt, proposals must protect openness, heritage assets including the Little Marlow Conservation Area, and the setting of the Chilterns National Landscape.

The human version (we wrote this, not the council)This policy requires a Landscape and Environmental Management Plan, known as a LEMP, wherever landscape mitigation, restoration or habitat creation is proposed. The plan must be secured through planning conditions or a legal agreement for at least 30 years or the full life of the development, whichever is longer. It must set clear management objectives, include baseline surveys of existing landscape and wildlife features, give detailed specifications for all planting and landscape elements, and identify who will manage the land and how it will be funded.

The human version (we wrote this, not the council)This section explains the landscape management policy. Management responsibility for new landscape areas will first be offered to the town or parish council, then to the local authority, with adoption plus a 30-year maintenance payment the preferred outcome. Management plans must cover monitoring, invasive species control, litter, public safety, measures against vandalism, and lighting controls to protect dark skies and rural character. The 30-year minimum period matches national biodiversity legislation and ensures improvements are sustained and adapted over time.

The human version (we wrote this, not the council)This policy protects agricultural land and soils. The best and most versatile farmland, Grades 1, 2 and 3a, must be protected from permanent loss wherever possible, with development steered to lower grade land (Grades 3b, 4 and 5) instead. Building on the best land is only acceptable where no suitable lower-grade alternative exists and the benefits clearly outweigh the land's long-term value for food production, climate resilience and ecosystem services. Soils must be managed sustainably, including saving and reusing topsoil during construction.

The human version (we wrote this, not the council)This policy requires affordable housing on developments of 10 or more homes or sites of 0.5 hectares or more. The rate varies by area: a minimum of 40% in the South, East and West (brownfield sites in the West subject to viability evidence), and 25% in the North and Central areas, rising to 50% on land in or released from the Green Belt. The tenure mix should be at least 60% social rent, 20% affordable rent and 20% shared ownership. Affordable homes must be spread through a development, look indistinguishable from market homes, and normally be built on site.

The human version (we wrote this, not the council)This section sets out the heritage assets policy in full. It extends protection to heritage at risk, historic townscapes in places such as Kenilworth, Royal Leamington Spa, Stratford-upon-Avon and Warwick, historic landscapes, and assets contributing to the Cotswolds National Landscape. Applicants affecting a heritage asset or its setting must assess its significance using appropriate expertise. Substantial harm to or total loss of a designated asset will be refused unless substantial public benefits outweigh it, while lesser harm must be justified and weighed against public benefits.

The human version (we wrote this, not the council)This policy protects Registered Parks and Gardens and Registered Village Greens, which are formally recognised historic landscapes. Development affecting them is only supported where it conserves and enhances their historic significance, landscape character, biodiversity value and public amenity. Proposals must be landscape-led, preserve historic design and planting, deliver measurable Biodiversity Net Gain, safeguard openness and tranquillity, restore lost features where appropriate, and maintain public access. A proportionate Landscape and Biodiversity Strategy is required, plus a Heritage Impact Assessment where a designated heritage asset is affected.

The human version (we wrote this, not the council)This section explains the policy on historic parks, gardens and village greens. It describes them as irreplaceable historic landscapes that contribute significantly to local character, identity and biodiversity, often containing mature trees and species-rich habitats. A landscape-led approach ensures development respects historic design intent and setting. The justification notes development can also bring opportunities to reinstate lost landscape features and improve public access, and that the required assessments make sure change is well informed and well managed.

The human version (we wrote this, not the council)This policy sets the requirements for data centre proposals. Applicants must show that enough electrical grid capacity can be secured, that electricity, digital connectivity and water needs can be met, and that noise, air quality and visual impacts are properly mitigated. Back-up generators should not use diesel, and sustainable heating and cooling should be used where feasible. In sensitive locations such as the Green Belt, applicants must show the development cannot go in a less sensitive place, and all proposals must evidence the need for the facility and its local economic benefits.

The human version (we wrote this, not the council)This policy supports rural diversification through the re-use and adaptation of existing rural buildings for employment uses, with new buildings only where re-use is not possible. Buildings must be of permanent and substantial construction, shown to be redundant or disused, and structurally suitable for conversion without major reconstruction. In the Chilterns National Landscape, extra conditions apply: the building must not have been erected within the last 10 years, and the new use must support the local rural community, economy or services.

The human version (we wrote this, not the council)This policy supports new or expanded tourism and visitor facilities within or next to existing settlements. Elsewhere, proposals must support the sustainable growth of existing facilities, involve converting or replacing existing buildings or support rural diversification, and be in an appropriate location that minimises environmental impacts. Seasonal structures such as marquees must be temporary and not harm the landscape. Existing tourism facilities cannot be lost unless replaced, shown to be no longer needed, or shown to be unviable after active marketing for 12 months. Buckinghamshire's tourism sector supports 2,125 businesses employing more than 21,000 people.

The human version (we wrote this, not the council)This policy requires development to conserve and enhance watercourses and their corridors, including their biodiversity, landscape, flood management and recreation value. Culverting or hard engineering of watercourses is not supported, and opportunities to restore rivers to a more natural state should be actively pursued. Development next to a watercourse must keep a natural buffer of at least 10 metres from the top of the bank, with no lighting, rising to at least 15 metres for chalk streams such as the River Chess and River Misbourne. Chalk streams are a globally rare habitat with stronger protection.

The human version (we wrote this, not the council)This policy protects wildlife species covered by international and national law, priority species listed under the Natural Environment and Rural Communities Act 2006, and species in significant decline. Where such species could be affected, proposals must be supported by proper ecological surveys and assessments by qualified professionals, carried out before permission is granted. Designs must follow the mitigation hierarchy of avoiding, minimising and compensating for impacts, with any residual impacts compensated at a minimum 2:1 basis. The Council also operates a district licensing scheme for great crested newts.

The human version (we wrote this, not the council)This policy requires development to deliver biodiversity net gain, meaning habitats must be left in a measurably better state than before. Unless nationally exempt, schemes must achieve at least 10% net gain if delivered on site or elsewhere within Buckinghamshire, rising to 20% if delivered outside the county. Gains are calculated using the latest statutory metric and should support the Local Nature Recovery Strategy. Buying statutory biodiversity credits is a last resort, and significant habitat creation must come with a long-term management and monitoring plan approved by the Council.

The human version (we wrote this, not the council)This policy requires development to deliver high-quality green infrastructure, the network of green spaces, trees, waterways and other natural features that benefits wildlife, flood management, health and recreation. Residential schemes of more than ten dwellings, or over 1,000 square metres of floorspace, must meet Natural England's Accessible Green Space standards and submit a Green Infrastructure Statement. These standards aim for good quality green space within a 15-minute walk of home. Green infrastructure must be managed for at least 30 years after completion, with arrangements to secure its management in perpetuity.

The human version (we wrote this, not the council)This policy protects trees, woodlands, orchards and hedgerows. There is a presumption to refuse development that would cause the loss or deterioration of ancient or veteran trees, ancient woodland, traditional orchards or important native hedgerows, except in exceptional circumstances with clear overriding public benefit. Minimum natural buffers are required, including fifty metres for ancient woodland, at least twenty-five metres for other woodland and five metres either side of hedgerows. Where trees could be affected, a tree survey to British Standard 5837 is required, and acceptable losses must be replaced with locally appropriate species.

The human version (we wrote this, not the council)This policy protects the county's most important nature sites, including the Chilterns Beechwoods, Burnham Beeches and Aston Rowant Special Areas of Conservation. Proposals must show they will not harm these sites, and a Habitats Regulations Assessment is required. The plan sets a 500 metre exclusion zone for new housing around Burnham Beeches and the Ashridge part of the Chilterns Beechwoods. Within wider Zones of Influence, developments must fund alternative green spaces (SANGs) and visitor management measures to reduce recreational pressure. Several strategic SANG sites and a Gateway site are allocated.

The human version (we wrote this, not the council)This policy sets the rules for Suitable Alternative Natural Greenspace (SANG), which is green space created to draw visitors away from protected nature sites. A SANG must provide at least eight hectares per 1,000 new occupants, a circular walk of at least 2.3km, one parking space per hectare, and be secured and managed for at least 80 years. It must be open before the homes relying on it are occupied. Developments of ten or more homes must contribute to a strategic SANG or provide their own; smaller schemes can rely on any strategic SANG in the zone.

The human version (we wrote this, not the council)This policy covers the 329 hectare Little Marlow Lakes area between Marlow and Bourne End, which sits in the Green Belt beside the River Thames. It allocates Spade Oak Lake as a strategic alternative green space (SANG) to reduce visitor pressure on Burnham Beeches, with parking off Muschallick Road, and supports wider outdoor recreation. Qualifying developments relying on the SANG must contribute financially and provide safe walking and cycling links between Marlow and Bourne End. Development must protect the river setting, lakes, wildlife, conservation areas and manage flood risk.
