New local plan supporting evidence
We're undertaking studies in support of the new Local Plan. You can find links to these studies on this page.
Aylesbury Vale review of housing capacity in the draft new Wycombe District Local Plan
GL Hearn, acting on behalf of Aylesbury Vale District Council, produced a review of the housing capacity of the Wycombe district. The review was submitted to Wycombe District Council in response to the consultation on the draft new Local Plan for the Wycombe district.
WDC housing land supply
This statement assess our housing supply against our updated objectively assessed need (OAN). We set out how our supply is calculated and include site by site information on each element of supply. This statement reflects our current policy position and will be updated once more in early 2017 when we finalise the evidence for the submission of our new Local Plan.
Housing fact sheets
We have produced a pair of notes which set out the background to housing numbers and distribution in the new Local Plan. The first of the notes covers issues relating to the District-wide allocation of housing, while the second relates to the two proposed site allocations at Bourne End.
Area of Outstanding Natural Beauty site assessment
We have produced a report which assesses whether there are any opportunities to meet our housing and economic development needs that should be identified in the Local Plan for villages that are located within the Chiltern’s Area of Outstanding Natural Beauty (AONB) but are not within the Green Belt.
Buckinghamshire green belt assessment
The assessment of the Buckinghamshire green belt is in two parts.
Part 2 green belt assessment
Part 2 assesses a number of sites within the Wycombe district, against the green belt purposes set out by the government in the National Planning Policy Framework. It also makes an initial assessment of their development potential.
The part 2 contains the main report and appendices which contain individual pro-formas which assess each site individually.
Part 1 green belt assessment
Part 2 follows on from a Buckinghamshire green belt assessment, which is known as the "part 1" assessment.
The methodology sets out how the Green Belt land parcels will be assessed against national green belt purposes. The annexes which accompany the study assesses the parcels of the Bucks Green Belt against the purposes for such land set out in the National Planning Policy Framework (NPPF). This will feed into Part 2 of the study, in which parcels will be looked at in more detail.
Built up areas within the Green Belt policy clarification
Early feedback on the draft Local Plan has highlighted a need to clarify our proposed approach to the ‘built-up areas within the green belt’ previously affected by policy GB4 of the current adopted Local Plan. This note is written to clarify the fact that we are in essence proposing to roll forwards the established approach in the draft plan.
Buckinghamshire housing market and functional economic areas
A report was jointly commissioned by the four Buckinghamshire district councils (Aylesbury Vale, Chiltern, South Bucks and Wycombe) to identify the housing market area(s) (HMA) and functional economic market area(s) (FEMA) that the Bucks districts lie within.
Following the announcement that Chiltern and South Bucks District Councils would jointly produce a Local Plan for their areas, a note was produced setting out the impact of the joint plan on the housing market area.
An update to the housing market areas and functional economic market areas report was produced in 2016 to take account of additional data that had been made available since the production of the original report.
Bucks Gypsy, Travellers and Travelling Showpeople accommodation assessment
We have a legal requirement to plan to meet the site/accommodation needs of Gypsies, Travellers and travelling showpeople. This study, published in August 2013 and updated in October 2014, has been carried out by consultants Opinion Research Services on behalf of the four districts in Buckinghamshire to provide robust, up to date evidence about the accommodation needs of Gypsy, Traveller and Travelling Showpeople in the period until 2023.
We have produced a paper which gives an overview of our targets for traveller pitch provision, our strategy to meet them, and an assessment of sites which are being considered to help meet future requirements.
We commissioned Boyer to provide commercial property advice on the appropriate provision of employment allocations and the scope for additional business development across several potential employment locations in terms of scale and type of employment floor space. We have used the report’s recommendations to advise our draft Local Plan.
Duty to cooperate
The "duty to cooperate" is a legal duty on authorities to work closely together in preparing their local plans to address strategic issues. To this end, together with Aylesbury Vale and Chiltern district councils, we produced a memorandum of understanding in August 2015 setting out how we will work together across various topic areas to meet the duty to cooperate. This was then updated in February 2016 to include South Bucks District Council as a part of the earlier agreement.
A separate memorandum of understanding was signed on 8 December 2016 between Wycombe and Aylesbury Vale District Councils setting out how we will work together to address unmet housing needs.
Economy study and employment land review
This draft report, produced by our consultants Peter Brett Associates, is an assessment of the District's future economic needs and a review of employment land.
Housing and economic development needs assessment (HEDNA)
The draft Housing and Economic Development Needs Assessment sets out the housing and economic development needs for the Buckinghamshire housing market area, consisting of Aylesbury Vale, Wycombe, Chiltern, and South Bucks districts.
An updated version of the HEDNA report has now been produced taking into account new data which has become available since the production of the original report.
The previous version of the HEDNA assessment was published in January 2016, and informed the draft version of the new Local Plan which was consulted on in June-August 2016.
Aylesbury Vale, Chiltern and Wycombe District Councils have jointly commissioned consultants to produce a housing and economic development needs assessment (HEDNA) to identify housing and economic needs for their new local plans. A methodology statement has been produced setting out how the assessment will be carried out.
The draft findings of the Bucks HEDNA have been shared at a series of stakeholder forums. The presentation which was given at those forums by our consultants may be viewed on this page.
Housing and economic land availability assessment (HELAA)
The housing and economic land availability assessment (HELAA) helps to identify future sources of land to help meet the district's development needs. It is a technical study of all potential housing, economic, and retail sites within Wycombe district. It was formerly referred to as the strategic housing land availability assessment (SHLAA).
A joint methodology was commissioned by Wycombe, Chiltern and Aylesbury Vale District Councils for their respective housing and economic land availability assessments (HELAA). The purpose of the assessment is to identify a future supply of land which is suitable, available and achievable for housing and economic development uses over the plan period.
Our draft Local Plan allocates land for a range of uses including housing, retail, and business. Appropriate infrastructure is required to ensure that future development is accompanied by the services and facilities needed.
We have produced an overview note which explains the various methods which we will use to secure the necessary infrastructure to support new development.
Our draft infrastructure delivery plan assesses the infrastructure needed to support new development in the Wycombe district.
Our community services team have also produced a note which assesses the need for a new cemetery in the Wycombe district.
A study has been produced estimating the canopy cover in Wycombe District. The study also compares other data on human health, wellbeing, and factors such as crime rates, house prices, social deprivation and life expectancy to observe if there was any correlation with tree canopy cover.
Landscape character assessment
The landscape character assessment provides a greater understanding of the landscape character of the Wycombe District which can be used to inform policy, planning and management actions. It consists of a main report, analyses of the various key landscape character types found in the Wycombe district, and five appendices.
Market research report
To help with the development of the new Local Plan, research was required to explore the views of residents regarding their perceptions, priorities and views on the shape of the plan and the issues it will provide guidance on. The study was designed to reach out to a broad and balanced profile of residents across the district according to location, age, gender and ethnic group.
This report by our consultants Qa Research was published in June 2014, and sets out the findings of the research.
The town centres and retail study appraises the district's town centres, estimates the scope for new retail floorspace and provides recommendations for a strategy for retail policy in the district.
Thames Water has identified a potential site to be safeguarded for a drinking water reservoir. The following documents identify the location and justification for safeguarding this site.
The settlement hierarchy study is an assessment of all the settlements in the district to assess the role they play and allow a judgement on their ability to accommodate growth.
Strategic flood risk assessment
An update to the original strategic flood risk assessment published in 2008 was produced in November 2014. This updated report assesses and identifies the risk of flooding from rivers and other sources of flooding, assesses the impacts of climate change on flood risk and makes recommendations for protecting against flooding.

Flood risk sequential test
We will be producing a flood risk sequential test document as a part of the evidence base for the new Local Plan. This document aims to demonstrate that the sites allocated for development in the new Local Plan have been proposed in those areas of lowest possible flood risk.
We have not been able to progress this piece of work because of recently published new allowances for climate change. This means we need to update the flood risk information contained within strategic flood risk assessment, which we use for the sequential test.
We will carry out this work over the summer, and publish a sequential test report when we publish the next stage of the new Local Plan, expected to be at the beginning 2017.
Strategic sites studies
As a part of assessing the development options to take forward as a part of the allocations process for the new Local Plan, an appraisal of the constraints and opportunities presented by a variety of sites has been carried out. In producing this study, the landscape assessment of the sites has been considered, along with other site-specific issues relating to a range of factors.
It should be noted that this assessment is for high-level development capacity setting purposes only and further assessment work will be required to confirm the conclusions reached and finalise the urban design principles for each site.
A sustainability appraisal is being produced in parallel with the preparation of the new Local Plan. This is because Local Plans are likely to have significant environmental effects. A sustainability appraisal ensures that potential environmental effects are given full consideration alongside social and economic issues.
This is the draft sustainability appraisal of the draft new Local Plan currently out for consultation. Due to its late publication the deadline for comments on the sustainability appraisal is midnight on 22 August 2016, however we still wish to receive responses to the local plan by 8 August 2016, and we will accept modifications to representations if so required in light of comments on the sustainability appraisal.
In February 2014 we published an issues and options consultation document on our new Local Plan, which was supported by an earlier version of the sustainability appraisal. This sustainability appraisal was made up of two documents. The initial sustainability appraisal report is the initial assessment of the impacts of the new Wycombe District Local Plan against social, economic and environmental objectives. The sustainability appraisal / strategic environmental assessment scoping report establishes the scope and the methodology for the sustainability appraisal process.
Transport assessment work
Assessments were produced to support the new Local Plan assessing the traffic impact of additional housing and employment-related land use in and around the High Wycombe and Princes Risborough urban areas, and the role of transport network improvements in mitigating that impact.
Buckinghamshire countywide traffic modelling
The consultants Jacobs were commissioned to assess the transport impact of the emerging local plan proposals for the districts within Buckinghamshire, comprising Aylesbury Vale, Chiltern, South Bucks and Wycombe.
This report covers the first phase of work, which primarily focuses on the identification of transport related issues to inform the development of potential mitigation options. There are three scenarios for the County - a "Do- Minimum" (DM) model run (essentially a base line reference case), and two "Do Something" (DS1 & DS2) forecast scenarios. DS1 includes a new settlement location at Haddenham and DS2 includes a new settlement location at Winslow. The report refers only to selected model outputs (Plots).
The second stage of work may include further model runs with refinements to the development scenarios and transport schemes to mitigate development impacts and contribute to the final submission.
Appendices A and B show the outputs for each scenario along with the base position from the model (county wide).
