Where protected species are known to be present or are potentially present, an appropriate survey of the application site should be undertaken prior to the submission of an application. Where protected species are found to be present, an assessment should be made of the likely impacts that the development would have on the species if permission were granted. If this impact can be mitigated against, then the application should be submitted with a set of the measures proposed that would be undertaken if permission were to be granted. Surveys need to be undertaken by a suitably experienced professional consultant at an appropriate time of year and employing appropriate survey techniques.
Applications for development in the countryside that will affect areas designated for their biodiversity interests are likely to need to include assessments of impacts and proposals for long term maintenance and management. This information might form part of an Environmental Statement, where one is necessary. Certain proposals which include work such as the demolition of older buildings or roof spaces, removal of trees, scrub, hedgerows or alterations to water courses may affect protected species and will need to provide information on them, any potential impacts for them and any mitigation proposals for such impacts.
Government planning policies for biodiversity are set out in the National Planning Policy Framework 2012 and a Government Circular: Biodiversity and Geological Conservation - Statutory obligations and their impact within the planning system (ODPM 06/2005) and Planning for Diversity and Geological Conservation: A Guide to Good Practice.
The relevant policies in the current Local Plan are E1 to E5.
