“Ground 4: Failure to Consider In-Combination Effects 36. The applications relating to the Northern Quarter have been brought forward piecemeal; this has meant that it has not been possible for the Council to properly assess the cumulative and in-combination impact of the development proposals. Thus it was unlawful for it to grant these permissions. The proper course for the Council was to refuse to grant permission until the spine road application had been prepared and properly scrutinized. 37. This piecemeal approach to the application process was raised as a serious issue a number of times by [Natural England] in their responses to statutory consultation and in the objections raised by [Friends of the Earth] and others. 38. Although each of the [likely significant effects] screening documents relating to the applications purport to consider each application in the light of its cumulative effects with the other and with the proposed spine road (a future application which will clearly form an important part of the overall project) this is a fiction. The proposals to mitigate the latest proposed alignment of the spine road are described in the Environmental Statement Addendum but now appear to be invalid because the route may vary and its consultation is “a long way away” and not sufficiently developed to be considered together at this time with the applications. It has also not gone out to public consultation nor been approved by [Natural England]. Without this information being completed, made available and approved (either through the overarching Masterplan requested by [Natural England] or through a properly evidenced planning application for the spine road) it is impossible for the Council to adequately consider the [likely significant effects] or to conduct an appropriate assessment in relation to either application before it. John’s Associates, the current Ecological Consultant for the proposals, themselves stated … “No Planning Application has as yet been made for the Spine Road so no fully detailed assessment (of in-combination effects) can be, or has been made.”
“The Council was not entitled to grant these permissions because no reasonable planning authority could have concluded that Regulation 61(5) of the 2010 Regulations was satisfied; and On the facts of this case it was unlawful to grant the permissions before final plans for the spine road were available.”
“61. Assessment of implications for European sites and European offshore marine sites (1) A competent authority, before deciding to undertake, or give any consent, permission or other authorisation for, a plan or project which – (a) is likely to have a significant effect on a European site or a European offshore marine site (either alone or in combination with other plans or projects), and (b) is not directly connected with or necessary for the management of that site, Must make an appropriate assessment of the implications for that site in view of that site’s conservation objectives. (2) … (3) The competent authority must for the purposes of the assessment consult the appropriate nature conservation body and have regard to any representations made by that body within such reasonable time as the authority specify. (4) … (5) In the light of the conclusions of the assessment, and subject to regulation 62 (considerations of overriding public interest), the competent authority may agree to the plan or project only after having ascertained that it will not adversely affect the integrity of the European site or the European offshore marine site (as the case may be). (6) In considering whether a plan or project will adversely affect the integrity of the site, the authority must have regard to the manner in which it is proposed to be carried out or to any conditions or restrictions subject to which they propose that the consent, permission or other authorisation should be given. (7) … (8) …”
“49. The United Kingdom is admittedly right in raising the objection that an assessment of the implications of the preceding plans cannot take account of all the effects of a measure. Many details are regularly not settled until the time of the final permission. It would also hardly be proper to require a greater level of detail in preceding plans or the abolition of multi-stage planning and approval procedures so that the assessment of implications can be concentrated on one point in the procedure. Rather, adverse effects on areas of conservation must be assessed at every relevant stage of the procedure to the extent possible on the basis of the precision of the plan. This assessment is to be updated with increasing specificity in subsequent stages of the procedure.”
“Natural England considers the level of information provided by the Biodiversity Strategy in relation to the two developments to be adequate enough to lift its objection set out in the letter of9th November 2012 . However, Natural England advises that the effectiveness of the mitigation measures proposed with these applications could be removed by future projects envisaged in the Area Action Plan. In particular the Council will need to carefully consider the imminent proposal to build the spine road and its relationship and interdependence with these two applications. For example the Council will need to consider the extent to which the proposed mitigation will impact and constrain the design of the spine road. …Whilst we believe that it is possible to mitigate the impact of the proposed spine road on European Protected bat species it is likely to be challenging from an engineering and design point of view and therefore costly. The Council may wish therefore to consider whether it represents sustainable development or of there are alternative options.”
“As you know the current applications fix the end points of the spine road as proposed by the [Action Plan]. This means that, if built, it is likely to cross important flight lines for bats … We appreciate that the Council has taken the decision as competent authority to assess the current schemes as standalone schemes because a) the proposal to build the full spine road is not imminent and consequently there is not enough information to assess and rule out impacts from it and b) the Council has obtained information to give confidence that the two current applications are completely independent of and not reliant upon any other development as set out within the [Action Plan] coming forward, and in particular are not reliant upon the development of the spine road, i.e. both developments could be successfully implemented even if no other proposals in the [Action Plan] came forward. We have removed our objection to the development on this basis. Whilst we have removed our objection …as specialist advisor on HRA matters we continue to advise you that … the impact of a future spine road could be even more significant because the applications for the new mitigation bat roosts place them in a location which will be separated from the [Special Area of Conservation] and the existing artificial roost by the probable route. We have pointed this out because the design and costs implications of bat mitigation for the current developments may remove flexibility and reduce options for the District Council and future developers when they seek to progress other developments (including the spine road). And we consider it sensible to make them aware of this in advance. However, we are not saying that the impact of the spine road on bat flight lines cannot be mitigated, rather that further survey work should be undertaken in order to determine whether impacts can be mitigated for, and what mitigation may be required. In order to help the Council plan the implementation for future elements of the [Action Plan], we have advised that any necessary mitigation for the spine road may be significant and may be fundamental to its overall design.”
