Potential Impact Pathways Impact Pathway NEB1: Impact on habitats and species due to land take 5.35 Further development of the borough’s assets and infrastructure could, depending on location and scale, result in the loss / fragmentation of areas of natural habitat as a consequence of land take. The scale and extent of any adverse effects would depend on the location, maintenance, and use of the new development and the nature conservation characteristics and value of the area affected (i.e. designated nature conservation sites). Impact Pathway NEB2: Impact on habitats and species due to changes in air quality 5.36 The continued use and development of the transport network and carbon based energy provision will give rise to atmospheric emissions, which contribute to air pollution at the local and regional scales. These pollutants have impacts on sensitive habitats (e.g. nitrogen deposition on heathland habitats such as Thursley, Ash, Pirbright and Chobham SAC). The scale and extent of adverse effects depend on the location and contribution of the sources such as proximity to an intensively used transport route or other emission source and the sensitivity of the surrounding natural environment to emissions to air. Impact Pathway NEB3: Impact of habitats and species due to changes in water quality 5.37 Further development of the borough’s assets and infrastructure could, depending on location and scale, result in changes in water quality and quantity and lead to an increased risk of eutrophication. Water habitats are vulnerable to the water table levels which are affected by abstraction volumes required to support an increased population. Climate change coupled with a lack of management (or inappropriate management) will exacerbate this risk. Impact Pathway NEB4: Impact of habitats and species due to disturbance 5.38 The continued use of existing development and infrastructure, and its maintenance and further development can result in the disturbance of species due to recreation, noise, vibration, and light pollution. The scale and extent of any adverse effects depend on the location and scale of any new development or maintenance activities and the location and vulnerability and sensitivity of the ecological components to the disturbance being produced. Consideration of Implications of Plan and Alternatives on Receptor ER01 Policy LP01: Strategy for the Location of Development 5.39 Three policy approaches within the SEA have an overall uncertain impact on ER01 (Appendix 4). However, this overall conclusion masks the adverse effect on impact pathway NEB1, NEB2 and NEB4. Whilst this raises concern it is an inevitable consequence of increasing the quantum of development outside the urban area. It is noted that the concentration of development in Addlestone significantly reduces the impact on the receptors. 5.40 The Level 6 HRA assessment has provided the Council with sufficient evidence for it to ascertain no adverse affect on the integrity of either Thames Basin Heaths SPA or Thursley, Ash, Pirbright and Chobham SAC as a result of the implementation of the Local Plan. The Level 6 HRA Report is presented in Appendices 8 and 9. 5.41 Having regard to the conclusion of SA in Appendix 3, overall, all the policy approaches have a mixed beneficial impact. It is noted that the impact on the air quality is adverse (RSF 16), whilst it also has a negative impact on the desire to conserve and enhance the region’s biodiversity (RSF 19). 5.42 The different approaches overall do not have a significantly different impact on this pathway. Policy LP02: Housing Provision and Distribution 5.43 All the policy approaches in the SEA (Appendix 4) have at least an uncertain impact, but LP02‐ A3(a) has an adverse impact on all the pathways. It is inevitable that development will have varying degrees of impact on the natural environment and bio‐diversity. It will always be a balance to ensure that the impact on ER01 is considered with the requirements for future development. It is inevitable that an unplanned approach to development (a no plan Page | 74 Runnymede BC FINAL Sustainability Appraisal Report – Feb 2013
scenario) will have a similar impact on the receptors. It will invariably come down to the appropriate scale of development to meet the needs of future generations. 5.44 The Level 6 HRA assessment has provided the Council with sufficient evidence for it to ascertain no adverse affect on the integrity of either Thames Basin Heaths SPA or Thursley, Ash, Pirbright and Chobham SAC as a result of the implementation of the Local Plan. The Level 6 HRA Report is presented in Appendices 8 and 9. 5.45 Having regard to the conclusion of SA in Appendix 3, overall, all the policy approaches have a neutral impact. It is noted that the impact on RSF 14 (the reuse of urban land) is undermined by the green field alternatives, whilst the impact on air quality is adverse (RSF 16) for all alternatives. There is again an adverse impact on RSF 20 – the impact on the natural and heritage environment. The need to accommodate growth will have a consequence for all the receptors, but the impact of the alternatives is not different for planned or unplanned growth. 5.46 LP02 in the SA consideration does not have a different impact to the alternatives. They are all neutral. Policy LP03: Development in Addlestone Urban Area 5.47 With regard to the SEA (Appendix 4) LP03‐A1 and LP03‐A2 have an uncertain impact, whilst LP03 has a neutral impact. The impact of the alternatives on the pathways is generally neutral, but LP03‐A1 and LP03‐A2 have an adverse impact on NEB2 – effect on habitats due to changes in air quality. This is overall a contained impact as the development is concentrated in the urban area. However, any development will have a wider impact on the natural environment and this is difficult to avoid as a result of the overall change in air quality. 5.48 Having regard to the conclusion of SA in Appendix 3, overall, all the policy approaches have a neutral impact. The impact on air quality is uncertain/adverse (RSF 16) for all alternatives and this is reflected on the impact on the pathways. The need to accommodate growth will have a consequence for all the receptors, but the impact of the alternatives is not different for planned or unplanned growth. Policy LP04: Development in Egham / Englefield Green Urban Area 5.49 The preferred options are noted to have a neutral impact on this receptor and individual with regard to the SEA (Appendix 4) 5.50 Having regard to the conclusion of SA in Appendix 3, overall, all the policy approaches have a neutral impact. The need to accommodate growth will have a consequence for all the receptors, but the impact of the alternatives is not different for planned or unplanned growth. 5.51 The overall impact of the alternatives in the SA consideration does not have a different impact, i.e. positive. Policy LP05: Royal Holloway UOL 5.52 The SEA conclusion (Appendix 4) for policy LP05 –A is that the policy will have an uncertain effect overall, whereas LP05‐A1 will have a neutral effect and LP05‐A2 will have an adverse effect. 5.53 With regard to impact pathway NEB1, impacts on habitats and species due to land take, the LP05 –A and LP05‐A2 both score an adverse effect, whereas LP05‐A1 scores a neutral effect. This is because LP05‐A1, to retain the college in the Green Belt, will not involve any further land take, and therefore the status quo is maintained with regard to habitats and species on the site. LP05 and LP05‐A2 will both involve land take and therefore habitats and species will be affected, whether the development is the subject of a master plan or not. 5.54 NEB2, impacts on habitats and species due to change in air quality scored a neutral effect for LP05 – A and LP05‐A1, and an adverse effect for LP05‐A2. LP05‐A1 maintains the status quo, which explains the neutral score, and although LP05 will involve development, the effects on air quality will be minimised by the control afforded by the masterplan (e.g. student numbers Page | 75 Runnymede BC FINAL Sustainability Appraisal Report – Feb 2013
