Green Belt & countryside

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.

The human version (we wrote this, not the council)This policy explains that most development in the Green Belt is inappropriate and will be refused unless very special circumstances apply. Exceptions include buildings for agriculture and forestry, facilities for outdoor sport and recreation, replacing or extending existing buildings, limited infilling within identified villages, and affordable housing on rural exception sites. Infill plots and buildings must be comparable in size to typical plots and houses in the village. The plan has also reviewed the Green Belt to identify Grey Belt land, but this policy applies to all Green Belt land.

The human version (we wrote this, not the council)This policy sets limits on extending or replacing buildings in the Green Belt. The resulting building must be no more than 50% larger than the original building's gross external floor area, with 'original' meaning the building as it stood on 1 July 1948 or as first built. Outside village built-up areas, domestic outbuildings must not exceed 25% of the original dwelling's floor area, cover no more than 50% of the garden area, or exceed 4 metres in height. Proposals must also respect the open character of the Green Belt.

The human version (we wrote this, not the council)This policy sets out when development is acceptable in countryside that lies outside the Green Belt. Supported categories include agriculture and forestry, outdoor sport, buildings for existing rural businesses, development within settlement built-up areas, rural exception housing, sites for Gypsies and Travellers, homes for rural workers, extensions, conversions of existing buildings and redevelopment of previously developed land. It also supports improvements to the Grand Union Canal network. The policy guides windfall sites (sites not specifically allocated in the plan) towards existing settlements as the most sustainable locations.

The human version (we wrote this, not the council)This policy protects the Chilterns National Landscape, which covers 27% of the council area and has the highest status of landscape protection. Development within it should be limited in scale, and development in its setting must be sensitively located and designed. All proposals must take a landscape-led approach, conserve the area's special qualities and follow the Chilterns Building Design Guide. Major developments will be refused unless exceptional circumstances are shown to be in the public interest, and must be supported by a Landscape and Visual Impact Assessment.

The human version (we wrote this, not the council)This policy requires all development to protect and enhance Buckinghamshire's landscapes. Proposals must draw on the county's Landscape Character Assessments, reflect local development patterns, reinforce local character, avoid harm to key views, and minimise light pollution at night and noise in quiet areas. They should also enhance public rights of way. Where harm to landscape character cannot be avoided, mitigation is required, with compensation only as a last resort, following the mitigation hierarchy in national planning policy.

The human version (we wrote this, not the council)This policy controls artificial light at night to protect wildlife, dark skies and local character. External lighting must be the minimum needed for safety and security, with light spill, glare and impact on the night sky minimised. Dark corridors, such as watercourses and hedgerow networks, must be protected because species like bats depend on them. A mitigation hierarchy applies: avoid lighting in sensitive areas first, then minimise it, then compensate. All lighting should have a clear purpose, be no brighter than necessary, use warmer colours where possible and be switched off when not needed.

The human version (we wrote this, not the council)This policy protects the delivery of two major rail projects. Development must not prejudice High Speed 2 or its environmental mitigation such as woodland and screening, and construction impacts on communities must be managed. It also protects East West Rail, including the proposed Aylesbury Link from Aylesbury station to Claydon Junction, and future upgrades to the Aylesbury to Princes Risborough line. New structures over these lines must allow for future double tracking and overhead electrification. Applicants within 50 metres of the routes are encouraged to consult Network Rail early.

The human version (we wrote this, not the council)This policy safeguards the route of the Buckinghamshire Greenway, a proposed flagship walking, wheeling and cycling route running north to south across the county. Development must not prejudice delivery of a 5 metre wide traffic-free corridor, though a 3 metre path may be accepted where space is constrained. Major sites of 10 or more homes (or employment equivalent) within 800 metres of the route must make proportionate contributions to its construction or provide convenient links to it. Sections at Waddesdon and the Misbourne valley have already been completed.

The human version (we wrote this, not the council)This policy requires all new housing and commercial developments to include underground ducting for telecommunications cabling, and sites for masts where extra mobile capacity is needed, unless developers can justify why this is not feasible. Above-ground equipment must be designed to minimise visual impact, and alternatives such as mast sharing must be considered. In sensitive locations like the Green Belt, National Landscape and conservation areas, the benefits of large masts must outweigh any harm. Equipment must be removed when no longer required.

The human version (we wrote this, not the council)This policy requires development proposals to align with the Buckinghamshire Design Code and national design guidance, and states that poorly designed proposals should be refused. Substantial weight is given to compliance with the code, and also to outstanding or innovative designs that promote sustainability or raise design standards, provided they fit their surroundings. Applicants may need to prepare local design tools for significant projects. The quality of an approved scheme must not be watered down between planning permission and completion.
