Draft A27 Chichester Bypass Mitigation Supplementary Planning Document (SPD) Version 2 - May 2024
7.0 Glossary
2016 SPD: This refers to the Planning Obligations and Affordable Housing Supplementary Planning Document that was adopted by the Council in 2016.
Apportionment and Averaging Factor: This is a number (factor) that has been calculated by the Council to allow the calculation of A27 mitigation contributions for any given size of dwelling or location within the south of the District. The Apportionment and Averaging Factors take account of car ownership (current and projected), site location and the likely impact that new dwellings will have on the A27 Chichester Bypass.
Community Infrastructure levy (CIL): A levy allowing local authorities to raise funds from owners or developers of land undertaking new building projects in their area. The Council introduced CIL in 2016.
Infrastructure Delivery Plan (IDP): This sets out the current planned and required infrastructure, when it will come forward, who will be leading on each aspect and the funding mechanisms and responsibilities required.
Local Plan: Key Policies (2014-2029): is the current local plan, adopted in 2015, that provides the policy basis for both the 2016 Planning Obligations and Affordable Housing SPD and this A27 Chichester Bypass Improvements: Planning Obligations SPD.
Local Plan Review (or Local Plan 2021-2039): is the emerging local plan that will, on adoption, replace the current local plan. The most recent version of the Local Plan Review is the Chichester Local Plan 2021 – 2039: Proposed Submission (Regulation 19), published in February 2023.
Material Consideration: Any factor relevant to the determination of a planning application or appeal, subject to limits set out in planning statute law, government circulars and guidance.
Mitigation: is the application of measures to avoid, minimize, or compensate for the adverse effects or harm created by new development.
National Highways (NH): Formerly known as 'Highways England' is an executive non-departmental public body, sponsored by the Department for Transport. They are responsible for managing the Strategic Road Network, of which the A27 is a part.
National Planning Policy Framework (NPPF): The suite of national planning policies to which planning decision makers must have regard in making planning decisions. The Council must also have regard to the NPPF in the preparation of local plans and other local planning documents. The latest version was published in July 2021.
Planning obligations: Planning obligations are legal obligations entered into to mitigate the impacts of a development proposal.
Section 106 Agreements (s106): are formal planning agreements entered into under section 106 of the Town and Country Planning Act 1990 by a person with an interest in the land and the local planning authority; or via a unilateral undertaking entered into by a person with an interest in the land without the local planning authority.
Section 278 Agreements (s278): are formal agreements entered into under section 278 of the Highways Act 1980 by a person with an interest in the land and the highways authority. These are often used to secure off-site highways works needed to mitigate the impacts of a development.
Strategic Road Network (SRN): is the major road network made up of motorways and trunk roads (including the most significant 'A' roads, such as the A27). They are administered by National Highways (formerly Highways England) which is an executive non-departmental public body, sponsored by the Department for Transport. All other roads in the District are administered by West Sussex County Council.
Target Contribution Level: This is the notional starting point for A27 mitigation contributions (per dwelling) and was calculated taking account of up-to-date area-based viability evidence that was published on the Council's website in January 2023. The Target Contribution Level is £8,000 per dwelling.
Viability Assessment: An assessment of the financial viability of a development, taking into account a range of different factors such as location, type of site, size of scheme and scale of contributions to infrastructure and facilities.
