Conservation in UK Law

If any proposed development would conflict with that objective, there will be a strong presumption against the grant of planning permission, though, no doubt, in exceptional cases the presumption may be overridden in favour of development which is desirable on the ground of some other public interest.

Drawing matters together, the task of the decision-maker is first to consider whether the risk of the project having a significant effect on the site's conservation objectives can be excluded. If it cannot, an assessment must be undertaken to ascertain the impact of the project and identify whether it is consistent with maintaining the site's conservation status.

I should like to make it clear that I do not see the word "demolition" as applying only where the proposal is that every single part of the listed building should be pulled down. It is now commonplace, especially in towns and cities, where the exterior of a building contributes to the architectural or historic interest of a group of buildings such as buildings in a terrace, for the façade to be left standing while clearing the remainder of the site for redevelopment.

For all these reasons, I am satisfied that there is no legal requirement that a screening assessment under Regulation 48(1) must be carried out in the absence of any mitigation measures that form part of a plan or project. On the contrary, the competent authority is required to consider whether the project, as a whole, including such measures, if they are part of the project, is likely to have a significant effect on the SPA.

There is a "strong presumption" against granting planning permission for development which would harm the character or appearance of a conservation area precisely because the desirability of preserving the character or appearance of the area is a consideration of "considerable importance and weight."

In the practical application of section 18A it will obviously be necessary for the decision-maker to consider the development plan, identify any provisions in it which are relevant to the question before him and make a proper interpretation of them. His decision will be open to challenge if he fails to have regard to a policy in the development plan which is relevant to the application or fails properly to interpret it.

I am satisfied that the loss of foraging habitat occasioned by cutting a swathe through the vegetation does not offend Article 12(1)(b) which is concerned with protection of the species not with conservation of the species' natural habitats. I am satisfied that that bald statement that the bats have to travel further and expend more energy in foraging does not justify a conclusion that the conservation status of the bats is imperilled or at risk.
