DRAFT Sustainability Appraisal Report for the Emerging Local Plan ...

is a reflection of the scale of development and the consequences of increased traffic
movement and other impacts of development on greenhouse emissions. It is difficult to
moderate this impact until detail proposals are in place but they are issues that need
consideration during detailed discussion.
11.43 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.
11.44 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).
11.45 LP01 overall does not have a significantly different impact to the alternatives.
Policy LP02: Housing Provision and Distribution
11.46 The LP02‐A2 alternatives have an uncertain impact with regard to the SEA (Appendix 4).
However, it is noted that LP02 and LP02‐A2(c) have an adverse impact and LP02‐A3(a) and
LP02‐A3(b) have a significantly adverse impact. The impact of the options is particularly
adverse when the pathways CG1‐3 are assessed. Large scale additional development will have
an impact on greenhouse emissions. It is lessened for the lower impact options but these do
not meet future need that may arise through further unplanned development.
11.47 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.
11.48 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 greenfield 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.
11.49 LP02 overall in the SA consideration does not have a different impact to the alternatives.
They are all neutral.
Policy LP03: Development in Addlestone Urban Area
11.50 The policy option LP03 has a mixed positive affect (Appendix 4). The impact of LP03‐A1 is
uncertain and the adverse impact of LP03‐A2 is noted It is of note that the alternative LP03‐
A2 is particularly adverse – illustrating the scale of development on green house emissions.
For A1 the impact is less but reflects the unplanned nature of the growth. LP03 is favoured as
its planned approach will enable the issues associated with climate change to be addressed.
11.51 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 the policy
options 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.
11.52 LP03 overall in the SA consideration does not have a different impact to the alternatives.
Policy LP04: Development in Egham / Englefield Green Urban Area
11.53 With regard to the SEA (Appendix 4) the adverse impact of LP04 will need to be considered in
the fuller assessment. The full impact of the LP04 on the pathways CG1‐3. This is a
consequence of additional development and the impact on climate change and in particular
greenhouse gas emissions. This is a consequence of meeting the needs of the future
