12 Glossary



Affordable Housing

Social rented, affordable rented and intermediate housing, provided to eligible households whose needs are not met by the market. Eligibility is determined with regard to local incomes and local house prices. Affordable housing should include provisions to remain at an affordable price for future eligible households or for the subsidy to be recycled for alternative affordable housing provision. Homes that do not meet the above definition of affordable housing, such as low-cost market housing, are not currently considered as affordable housing for planning purposes.

Area of Outstanding Natural Beauty (AONB)

A landscape where the distinctive character and natural beauty is so outstanding that it is in the nation's interest to safeguard it. Aylesbury Vale district includes part of the Chilterns AONB. The AONB is managed by the Chilterns Conservation Board.

Aylesbury Vale District Local Plan (AVDLP)

The spatial development plan for Aylesbury Vale used to determine planning applications. Adopted by Aylesbury Vale District Council (AVDC) in February 2004, only some of the policies have been saved for use in planning decisions. The AVDLP will be replaced by the Vale of Aylesbury Local Plan (VALP) and neighbourhood plans.

Black or Ethnic Minority (BME)

A socio-economic grouping used with other such groups in housing and economic analysis including from the latest Census data. Utilised within background studies informing the Plan.


A collective term for plants, animals, micro-organisms and bacteria which, together, interact in a complex way to create living ecosystems.

Brownfield Register

A register of locally identified brownfield  sites (previously developed land) suitable for housing which is in the process of being implemented

Climate Change

The lasting and significant change in weather patterns generally agreed to be caused as a result of higher global temperatures brought about by greenhouse gas emissions over periods ranging from decades to hundreds of years, impacting on river and sea levels and the rate of flows on watercourses.

Community Infrastructure Levy (CIL)

A charge on new buildings and extensions to help pay for supporting infrastructure. This new charge replaces the Section 106 tariff, but Section 106 agreements will still be used for the specific impacts of a development (such as a new access road) and for affordable housing. Unlike Section 106, CIL is non-negotiable and collection is purely an administrative process. The levy and what it covers is set out in a charging schedule that is consulted on prior to submission to Government and a public examination prior to adoption by the Council.

Conservation Area

A locally designated area (by AVDC for conservation areas in the Vale) of special architectural interest, where the character or appearance is desirable to preserve or enhance. AVDC carries out occasional reviews of the special interest through character appraisals and management plans.

Council Monitoring Reports

Monitoring reports are published regularly usually covering a financial year. The first purpose of the reports is to review the progress of planning policy documents, secondly to assess the effectiveness of existing planning policies and identify whether any policies are not being implemented, or should be amended or replaced. The second of these tasks is achieved by reporting against a number of indicators. Housing land supply is monitored more frequently and AVDC publishes regular five-year land supply position statements.

Community Facilities

Multi-purpose community buildings such as community centres, village halls, church halls, indoor and outdoor sports facilities available for public and community use and public open space including green infrastructure

Cultural Facilities

Purpose-built arts and entertainment venues such as cinemas, theatres and arts centres

Department for Communities and Local Government (DCLG)

The Department of Communities and Local Government sets national planning policy in England, as well as determining what local government does, how well it is working and how it is funded.

Development Plan

The statutory development plan for determining planning applications and appeals in the district. This currently comprises the Adopted Aylesbury Vale District Local Plan (AVDLP) 2004 saved policies, any made neighbourhood plans and the Buckinghamshire Minerals and Waste Local Plan. Vale of Aylesbury Local Plan (VALP) will replace AVDLP when adopted.

Duty to


The 'duty to co-operate' is a legal requirement on the Council in the VALP plan preparation process. The duty concerns the Council and neighbouring district/borough councils, county councils and other identified public bodies. The Council is required to provide sufficient evidence to demonstrate that the duty has been undertaken appropriately for the Plan.

East-West Rail

A new railway network, partly using existing track that will connect Reading and Oxford across to East Anglia via Milton Keynes, Bedford and Cambridge. In the shorter term, the East West Rail Consortium's priority is to deliver the western section of the route comprising Reading to Milton Keynes and Bedford via Oxford and also Milton Keynes to Aylesbury. There will be a new station at Winslow due to be built on the line between the Aylesbury spur/Bicester and Bletchley. This is planned to be open by March 2019.

Economic Development

Any development for the following Use Classes A1 (Shops), A2 (Financial and Professional Services), A3 (Restaurants and Cafés), A4 (Drinking Establishments), A5 (Hot Food Takeaways), B1 (Business), B2 (General Industrial), B8 (Storage and Distribution), C1 (Hotels), D1 (Non-residential institutions), D2 (Assembly and Leisure) and Sui Generis uses (other than Houses in Multiple Occupation and Hostels. The term 'economic development' land is mainly used in the Housing and Economic Land Availability Assessment (HELAA) study.

Extra Care Housing

Housing which offers self-contained accommodation together with communal facilities and where care, as well as support services, are provided on site.

Flood Zones

Areas of land assessed as being of low risk (Flood Zone 1), medium (Flood Zone 2), high (Flood Zone 3a) and the functional floodplain (Flood Zone 3b) where no development should take place. The Environment Agency identifies where the flood zones are and reviews them quarterly. AVDC must carry out a strategic flood risk assessment to support VALP that will look at all forms of flooding and the impact of flood defences. Guidance on planning and flood risk is set out in the NPPF and Planning Practice Guidance.

Green Belt

A policy designation for controlling urban growth to prevent neighbouring towns from merging into one another, assist in safeguarding the countryside from encroachment, preserve the setting and special character of historic towns, and assist in urban regeneration, by encouraging the recycling of derelict and other urban land. Within the Green Belt, guidance for which is set out in the National Planning Policy Framework, land is to be kept permanently open and only used for agriculture open space, forestry and outdoor recreation and limited infilling of villages and previously development land.

Green Infrastructure

A planned network of high quality multi-functional green space and interconnecting links in, urban and rural areas with environmental features designed in delivering a wide range of environmental social and economic quality-of-life benefits for local communities. AVDC has published a Green Infrastructure Strategy and has contributed to a Buckinghamshire Green Infrastructure Delivery Plan.

Greenfield land

Land which has not been previously developed.

Gypsy, Traveller and Travelling Showpeople Needs Assessment

The Government requires each local planning authority to set pitch targets for Gypsies and Travellers and plot targets for Travelling Showpeople which address the likely permanent and transit site accommodation needs of Travellers in their area. The four district authorities in Buckinghamshire have worked collaboratively to bring forward a traveller accommodation needs assessment in conjunction with Opinion Research Services (ORS).

Habitats Regulations Assessment (HRA)

(Appropriate Assessment)

Habitats Regulations Assessment (HRA) is required under the European Directive 92/43/EEC on the 'conservation of natural habitats and wild fauna and flora for plans' that may have an impact of European (Natura 2000) Sites. The sites relevant to Aylesbury Vale are two Special Areas of Conservation.

HRA is the assessment of the impacts of implementing a plan or policy on a Natura 2000 Site. Its purpose is to consider the impacts of a land-use plan against conservation objectives of the site and to ascertain whether it would adversely affect the integrity of the site. Where significant negative effects are identified, alternative options should be examined to avoid any potential damaging effects.

Heritage Assets

A collective term for either designated or non-designated assets.  Designated assets are listed buildings, scheduled monuments, registered historic parks and gardens, registered battlefields and conservation areas.

High Speed 2 Rail (HS2)

The Government's proposed high speed railway line from London to Birmingham (phase 1 due to open in 2026) and the north of England (phase 2), cutting through the district from the southeast near Wendover and Aylesbury to northwest near Turweston. The Council is working with Buckinghamshire County Council and other partner organisations to minimise its impact if it does go ahead.

Historic Environment

A collective term to encompass people's interaction with heritage assets which include buildings, monuments, sites, places, areas or landscapes identified as having a degree of significance meriting consideration in planning decisions because of their heritage interest.

Historic Parks and Gardens

The Register of Historic Parks and Gardens of special historic interest in England provides a listing and classification system for historic parks and gardens similar to that used for listed buildings. The register is managed by Historic England under the provisions of the National Heritage Act 1983. Over 1,600 sites are listed, ranging from the grounds of large stately homes to small domestic gardens, as well as other designed landscapes such as town squares, public parks and cemeteries.

Homes and Communities Agency (HCA)

The national housing and regeneration agency for England. The agency contributes to economic growth by helping communities to realise their aspirations for prosperity and to deliver high-quality housing that people can afford. The HCA provides investment for new affordable housing and to improve existing social housing, as well as for regenerating land.

5 Year Housing Land Supply

The supply of specific deliverable housing sites on which housing completions are expected. The five-year housing land supply is the number of dwellings expected to be completed in the next five years, compared to the Local Plan target for the next five years (this is normally expressed in terms of the number of years worth of supply).

Housing Market Area (HMA)

The best-fit Housing Market Area (HMA) has been defined as Aylesbury Vale, Wycombe and Chiltern Council areas following work by Opinion Research Services (ORS). The HMA is the basic area for determining housing  need through the Housing and Economic Development Needs Assessment

Housing and Economic Land Availability Assessment (HELAA)

A key component of the evidence base to support the delivery of sufficient land for housing and employment to meet the community's need for more homes. The HELAA is an assessment to identify land for housing and assess the deliverability and developability of sites. These assessments are required by the National Planning Policy Framework.

Housing and Economic Development Needs Assessment (HEDNA)

A Housing and Economic Development Needs Assessment (HEDNA) is a study required by Government of Local Planning authorities to inform Local Plans in terms of housing targets, housing need, demand, migration and commuting patterns and the development of planning and housing policy as well as the future quantity of land or floorspace required for economic development needs. For Aylesbury Vale the HEDNA has been undertaken by Opinion Research Services (ORS) for the Central Bucks HMA.

Housing trajectory

A table (optionally accompanied by a graph) included in the Local Plan which sets out information on past and projected annual housing completions in comparison to the Local Plan target. The trajectory is a tool for analysing and illustrating whether or not housing delivery is on track.

Infrastructure Delivery Plan (IDP)

The IDP's role will be to identify all items of infrastructure needed to ensure the delivery of the growth targets and policies contained in the VALP. This ensures that an appropriate supply of essential infrastructure is provided alongside new homes, workplaces and other forms of development up to 2033.

Listed building

A listed building is a building that has been placed on the Statutory List of Buildings of Special Architectural or Historic Interest.

Live Work Space

Property that is specifically designed for dual use, combining both residential and employment space. It is regarded as sui generis ('in a class of its own')[1] but for ease of enforcement the work element will be regarded as a separate A2 or B1 activity and will be conditioned as such. (B2 may be considered where no other residential property is affected but B8 will not, given its low employment density.) Live/Work is distinct from conventional 'home working' which usually comprises a residential unit with ancillary and often temporary or informal work areas. Such businesses do not normally require planning permission. Live/Work is a distinctive and formal division of residential and workspace floorspace which does require planning permission.

Local Green Space

Areas of green space of importance to local communities which are designated as such and protected preventing their future development unless under very special circumstances

Localism Act

An Act of Parliament which is the primary legislative basis for local authority planning powers which came into force following gaining Royal Assent in November 2011. The Act made provision for new regulations to be made including on plan making (came into force in April 2012) and a basis for the review of existing planning policy (the National Planning Policy Framework was published in March 2012).

Local Development Scheme (LDS)

The detailed timetable and project plan of all development plan documents and supplementary planning documents that are to be produced over a set period – normally three years.

Local Enterprise Partnership (LEP)

A voluntary partnership between local authorities and businesses formed in 2011 by the Department for Business, Innovation and Skills to help determine local economic priorities and lead economic growth and job creation within its local area. They carry out some of the functions previously carried out by the regional development agencies which were abolished in March 2012. The two LEPs that involve AVDC are the South East Midlands LEP (covering Aylesbury Vale, Central Bedfordshire, Milton Keynes Council, South Northamptonshire District and other Bedfordshire and Northamptonshire districts) and the Buckinghamshire Thames Valley LEP (covering all of Buckinghamshire).

Local Geological Site

Local sites are non-statutory areas of local importance for nature conservation that complement nationally and internationally designated geological and wildlife sites (previously Regionally Important Geological Sites).

Local Nature Reserve

Local nature reserves are for both people and wildlife. They are places with wildlife or geological features that are of special interest locally for both people and wildlife.

Local Nature Partnership (LNP)

A body, designated by the Secretary of State for Environment, Food and Rural Affairs, established for the purpose of protecting and improving the natural environment in an area and the benefits derived from it. There is one LNP covering Aylesbury Vale; this is called the Buckinghamshire and Milton Keynes Natural Environment Partnership, established in 2012, including the Delivery Group.

Local Plan

The statutory development plan for determining planning applications and appeals for the district. This is currently any made neighbourhood plans and the Aylesbury Vale District Local Plan (AVDLP) 2004 saved policies until AVDLP is replaced by the Vale of Aylesbury Local Plan.

Local Wildlife Site

Previously known as Sites of Importance for Nature Conservation or County Wildlife Sites, these are areas of land with significant wildlife value. They are typically an area of ancient woodland, a flower-rich hay meadow or a village pond.

Market Housing

Private housing for rent or for sale, where the price is set in the open market.

National Planning Policy Framework (NPPF)

The National Planning Policy Framework (NPPF) is the Government's statement of national planning policy and all Local Plans must be in general conformity with it and this is tested at a Local Plan Examination. The NPPF was published on 27 March 2012 and replaced numerous planning policy guidance documents, statements and circulars. It was accompanied by Technical Guidance to the NPPF on flood risk, on minerals and waste and a planning policy statement on Traveller sites.

Neighbourhood Plan

A type of planning policy document that after 'making' can be used (alongside the Aylesbury Vale District Local Plan/ Vale of Aylesbury Local Plan) to determine planning applications. The plans are prepared by a parish/town council or designated neighbourhood forum for a particular neighbourhood area (made under the Localism Act 2011) and have to be in general conformity with the district plan, undergo Examination and a Referendum. A neighbourhood plan should support strategic development needs set out in the Local Plan and plan positively to support local development. A neighbourhood plan becomes part of the statutory development plan once it has been made (brought into legal force) by the local planning authority.

Office for National Statistics (ONS)

The UK's largest independent producer of official statistics and the recognised national statistical institute of the UK.

Planning in Principle (PIP)

The Homes and Planning Act 2016 requires local authorities to keep a register of brownfield land within its area capable of being granted 'planning permission in principle' (PIP) for housing. Proposals include extending PIP for sites identified in local and neighbourhood plans providing permission in respect of matters relating to location, uses and the amount of development on particular sites.

Planning Practice Guidance

Practical guidance that supplements policy in the National Planning Policy Framework. The Government launched the Planning Practice Guidance on 6 March 2014, replacing a raft of separate detailed best practice guidance covering many areas of town planning issues.

Primary and Secondary Shopping Frontages

Cover specified rows of ground floor units within identified town centres and seek to retain activity-generating uses including a high proportion of retail uses which may include food, drinks, clothing and household goods. Secondary frontages provide greater opportunities for diversity of uses within the frontages such as restaurants. The defined frontages from AVDLP have been reviewed in the Aylesbury Vale Retail Study, 2015.

Primary Shopping Area

An area defined in a Local Plan where retail development is concentrated (generally comprising the primary and those secondary frontages which are adjoining and closely related to the primary shopping frontage).

Previously-Developed (Brownfield) Land

Land which is or was occupied by a permanent structure, including the curtilage of the developed land (although it should not be assumed that the whole of the curtilage should be developed) and any associated fixed surface infrastructure. This excludes: land that is or has been occupied by agricultural or forestry buildings; land that has been developed for minerals extraction or waste disposal by landfill purposes where provision for restoration has been made through development control procedures; land in built-up areas such as private residential gardens, parks, recreation grounds and allotments; and land that was previously developed but where the remains of the permanent structure or fixed surface structure have blended into the landscape in the process of time.

Registered Providers of affordable housing

A registered provider of social housing as defined in Chapter 3 of Part 2 of the Housing and Regeneration Act 2008 who is registered with the Homes and Communities Agency and has not been removed from the register.

Rural Exception Sites

Small sites used for affordable housing in perpetuity where

sites would not normally be used for housing. Rural exception sites seek to address the needs of the local community by accommodating households who are either current residents or have an existing family or employment connection. Small numbers of market homes may be allowed at the local authority's discretion, for example where essential to enable the delivery of affordable units without grant funding.

Self Build and Custom Housing


The Homes and Planning Act 2016 requires local authorities to keep a register of people seeking to acquire land to build or commission their own homes and to grant sufficient suitable development permissions of serviced plots to meet demand.

Scheduled Ancient Monuments

Nationally important archaeological site or historic building, given protection against unauthorised change.

Sensitive Landscapes

'Sensitive landscapes' is a term used in an evidence base prepared by Jacobs for the Council in 2008 called the 'Areas of Sensitive Landscapes' study. All landscapes in the district were surveyed. Six factors were used to determine what made an area sensitive. These were: scenic quality, rarity, representativeness (locally and regionally) and tranquillity. The Government uses the term 'valued' landscape as meaning important local landscapes that contribute to the quality of the natural and local environment. The valued landscapes for the district are the AVDLP designated Areas of Attractive Landscape and Local Landscape Areas. These have had a review and criteria based assessment by LUC in 2015.

Settlement Hierarchy

A way of identifying and arranging the largest settlements into an order for the purposes of distributing the VALP housing and employment land growth to towns and villages around the district based upon their population and sustainability criteria.

Site Allocations

Designations of land use, types and levels of development and other details identified in a Local Plan. There are existing site allocations in the Adopted Aylesbury Vale District Local Plan 2004 and several made neighbourhood plans. Future allocations will be made in VALP or in further made neighbourhood plans.

Sites of Special Scientific Interest (SSSI)

A national designation indicating one of the country's very best wildlife and/or geological sites. SSSIs include some of the most spectacular and beautiful habitats: wetlands teeming with wading birds, winding chalk rivers, flower-rich meadows, windswept shingle beaches and remote upland peat bogs.

Special Areas of Conservation

An area which has been given special protection under the European Union's Habitats Directive. SACs provide increased protection to a variety of wild animals, plants and habitats and are a vital part of global efforts to conserve the world's biodiversity. The two SACs relevant to the VALP are the Chiltern Beechwoods and Aston Rowant. The impact of the VALP proposals on these will be considered in the Appropriate Assessment/Habitats Regulations Assessment.

Starter Homes

The  Housing and Planning Act 2016 requires local authorities to ensure  starter homes are built and sold to young first time buyers below 40 years of age at a minimum 20% discount below open market value. Regulations will consider the requirement for 20% of such homes on sites of a certain size.

Strategic Flood Risk Assessment (SFRA)

A study and final report identifying all types of flood risk in the district and the considerations that development should adhere to including avoiding building in higher areas of flood risk and incorporating mitigation measures including sustainable drainage systems. A new SFRA will be prepared to support the growth identified in VALP.

Supplementary Planning Document (SPD)

More detailed planning guidance to supplement what is in Development Plan Documents. SPDs cannot make new policy; there must be 'policy hook' to a policy or proposal in a Development Plan Document.

Sustainability Appraisal

An evaluation of the social, environmental and economic effects of policies and proposals in the VALP. The purpose is to ensure that the Local Plan documents are produced in accordance with the Government's definition of sustainable development included in the NPPF. Sustainability Appraisals are carried out in line with Government Guidance to meet the terms of Strategic Environmental Assessment which are required under an EU Directive.

Sustainable Construction

An approach to construction that reduces the environmental impact of a building over its entire lifetime, while optimising its economic viability and the comfort and safety of its occupants. A building designed and constructed in a sustainable way minimises the use of water, raw materials, energy and land over the whole life cycle of the building.

Vale of Aylesbury Local Plan (VALP)

The new planning policy document for the district covering the period 2013-2033 which will replace the adopted Aylesbury Vale District Local Plan 2004. VALP is referred to as the 'Local Plan' in the VALP Issues and Options consultation document, October 2015.

Water Cycle

A term used for the assessment of the impact of development on wastewater treatment work capacity, surface water management, wastewater networks, water quality and water supplies.

Windfall Sites

Sites which have not been specifically identified as available in the Local Plan process. They normally comprise previously-developed sites that have unexpectedly become available for new development.
