SA Addendum Scoping Report

4 Method to be used for SA Addendum work


4.1       As described in Chapter 1, the SA Addendum work will incorporate the requirements of the SEA Regulations. The approach to carrying out the SA Addendum for the Joint Core Strategy will be based on current best practice and the following guidance:

  • A Practical Guide to the SEA Directive (September 2005), Office of the Deputy Prime Minister, Scottish Executive, Welsh Assembly Government and the Department of the Environment for Northern Ireland.

4.2       The SA will be undertaken in close collaboration with those involved in considering the alternatives for the Joint Core Strategy in order to fully integrate the SA/SEA process with the production of the Plan.

Part 3 of the SEA Regulations 12(5) states that: when deciding on the scope and level of detail of the information that must be included in the report, the responsible authority shall consult the consultation bodies.    


4.3       The "detail" as referenced above includes the policy, plan and programme review, the environmental baseline and sustainability issues (including their likely evolution without the Plan) as set out in earlier sections of this Scoping Report, and the information that will be included in the SA report.

4.4       The "scope" includes the range of SA objectives that will be used to assess the effects of the alternatives for the Joint Core Strategy and the approach to that will be taken to the appraisal of "reasonable alternatives" (see below). This information is being consulted on as part of the consultation on this Scoping Report.

Approach to the Assessment

4.5       The SEA Regulations set out the material to be included within the SEA Environmental Report.

Part 3 of the SEA Regulations 12(2) require that: The report shall identify, describe and evaluate the likely significant effects on the environment of:

(a) Implementing the plan or programme; and

(b) Reasonable alternatives taking into account the objectives and the geographical scope of the Plan or Programme.    


4.6         As described in Chapter 1, the specific alternatives for three of the elements of Addendum work are still being defined and will be assessed against the reasonableness criteria.

4.7         The SA will clearly set out how the reasonable alternatives perform in comparative terms, and will describe the reasons for selecting the preferred options, and why other reasonable alternatives have been discounted.

The SEA Regulations, Schedule 2(6) require the Environmental Report to consider:

The likely significant effects on the environment, including short, medium and long term effects, permanent and temporary effects, positive and negative effects and secondary, cumulative and synergistic effects, on issues such as (a) biodiversity, (b) population, (c) human health, (d) fauna, (e) flora, (f) soil, (g) water, (h) air, (i) climatic factors, (j) material assets, (k) cultural heritage including architectural and archaeological heritage, (l) landscape and (m) the inter-relationship between the issues referred to in sub-paragraphs (a) – (l).    

SA Framework

4.8         The SA will take an "objectives-led" approach to the assessment that will address the sustainability issues identified while ensuring all the SEA topics (a) to (l) in the box above are covered. It is proposed to use the same SA Framework as was developed originally for the SA of the Joint Core Strategy, and presented in the 2006 SA Scoping Report, which included a set of SA objectives covering all of the SEA topics. Following the original scoping consultation, the SA Framework was updated to reflect statutory consultee comments in the 2007 SA Report (Table 3), and the same updated SA Framework continued to be used in the 2009 SA Report (Table 6.1) and 2011 SA Report (Table 6.1). Using the same SA Framework for this SA Addendum work will ensure that alternatives are assessed in a comparable way to the options previously considered as part of developing the Joint Core Strategy. The SA Framework is re-presented below in Table 4.1.

Predicting effects

4.9      The assessment will focus on the likely significant effects of implementing the reasonable alternatives for each of the four components being addressed in the Addendum work, and the final SA Report Addendum will, where possible and reasonable, distinguish between and report on the different types of effects (listed in the box above, i.e. temporal, cumulative etc.).

4.10       The assessment will be carried out using a matrix based approach. For each reasonable alternative, the matrix will describe:

  • The nature of the effect against each of the SA objectives, including whether it is likely to be positive or negative, permanent or temporary, and the timescale of the effect.
  • For each effect identified, the scope for mitigation (including reference to other policy or regulatory safeguards, either at the national level or through other policies in the Joint Core Strategy).
  • Recommendations for further mitigation or improvements to the Joint Core Strategy to provide more in the way of positive effects will be put forward.
  • The likely residual effects, taking into account mitigation.

4.11 Symbols will be used to summarise the effects identified as follows:




Significant positive effect likely




Minor positive effect likely




Negligible effect likely




Minor negative effect likely




Significant negative effect likely




Mixed effect likely




Likely effect uncertain




Policy is not relevant to SA objective


4.12       In carrying out the SA use will be made of Geographical Information Sytems (GIS) which provide mapped data of key factors of relevance to the identification of significant effects such as:

  • Landscape, biodiversity and cultural heritage designations.
  • Agricultural land classifications.
  • Areas at risk of flooding.
  • Mineral deposits.
  • Areas of social deprivation.
  • Location of employment, retail, community facilities (e.g. schools and hospitals), neighbourhood centres.
  • Transport network including public transport (bus, rail).

4.13       It will also be informed by the most recent technical studies including those listed as the Evidence Base within the Hearings Document List (18 April 2013) as well as any updates since that list was produced, and relevant documents submitted to the Hearings and subsequently by representors.

4.14       The SA will also take into account the findings of the Habitats Regulations Assessment (HRA) also being undertaken by LUC.

4.15       Once the JPU has selected its preferred options from the reasonable alternatives being considered as part of the Addendum work, cumulative effects will be considered by comparing the likely effects of the preferred options with the effects identified for the remainder of the Joint Core Strategy (in the 2011 SA Report) in order to consider the cumulative effects of the potential revisions to the Joint Core Strategy as a whole. Consideration will also be given to cumulative effects arising from proposed development in West Northamptonshire alongside development in neighbouring local authorities. This will be undertaken through a review of the plans and accompanying SA reports prepared by neighbouring authorities.

Consultation on the SA Report Addendum

4.16       The results of the appraisal will be reported in the SA Report Addendum prepared alongside any proposed modifications to the Joint Core Strategy that the JPU decides to put forward for the inspector to consider at the further hearings in December 2013. The consultation on the objectively assessed housing needs study, the SA Addendum and proposed modifications to the Joint Core Strategy will be for a 6 week period in October and November 2013

Proposed structure of the SA Report Addendum

4.17       The SA Addendum Report will be designed to complement the SA Report already published. It will include, as appropriate, all the component parts required under Schedule 2 of the SEA Regulations:

  • An outline of the contents of the plan and its relationship with other relevant plans and programmes, including the work already undertaken.
  • The environmental, social and economic characteristics of the plan area as relevant to the SA Addendum work, including any problems and issues identified and their likely evolution without the plan.
  • Key environmental, social and economic policy objectives set at the international, national and local level, of relevance to the SA Report Addendum.
  • The SA framework, and the assumptions used in coming to judgements on the effects of the draft plan.
  • The reasonable alternatives considered and why these were selected, how they performed in sustainability terms, and the reasons for selecting the alternatives included in the plan and the reasons for rejecting reasonable alternatives.
  • Any difficulties encountered during the appraisal process, including lack of knowledge.
  • How consultation comments were taken into account from the earlier stages in the appraisal process, and how they have been dealt with.
  • The significant effects of the preferred alternatives (including cumulative effects) under each of the objectives in the appraisal framework, taking into account mitigation (which may take the form of policy safeguards in national policy, the Core Strategy, or other regulatory mechanisms).
  • The influence of the SA process on the modifications to the Joint Core Strategy.
  • Proposed monitoring framework for significant effects identified (including uncertain effects where these could become significant).
  • A Non-Technical Summary (of the matters listed above).

4.18       The SA Addendum Report will need to reflect any proposed modifications to the Joint Core Strategy. It will also need to incorporate the findings of the HRA.


4.19        The purpose of monitoring under the SEA Regulations is to measure the sustainability effects of the Joint Core Strategy (in particular the likely significant or uncertain effects) and to identify any unforeseen adverse effects, enabling appropriate remedial action to be taken at an early opportunity. It is recognised that the monitoring requirements typically associated with the SA process can place heavy demands on authorities. Therefore the monitoring strategy will, wherever possible, build on existing monitoring that is being undertaken, using indicators and datasets that are already being routinely collected. For example, it should be possible to utilise the monitoring that is already undertaken for West Northamptonshire as part of its Annual Monitoring process. The monitoring proposed in the SA Report Addendum will update and amend as necessary the relevant parts of the monitoring programme in Table 8.1 of the 2011 SA Report, based on any significant effects identified for the preferred alternatives selected by the WNJPU.
