There’s a separate template for phased developments
For phased developments there are separate requirements. You will need to complete:
an overall biodiversity gain plan
a phase biodiversity gain plan
The statutory framework for biodiversity net gain has been designed to take account of the fact that, for a long term phased development, a section 73 permission can sometimes be granted after the original permission has been commenced to change the conditions related to development, including future phases, and this section 73 permission is a separate permission to the original permission.
In the first instance, if a section 73 permission for phased development does not affect the post-development value of the onsite habitat of the entire development or affect irreplaceable habitats (including any compensation arrangements) as specified in an earlier plan, the Overall Biodiversity Gain Plan for the original permission is regarded as approved for the section 73 permission and a new Overall Plan would not need to be submitted and approved. Similarly, any Phase Plan which has been approved would continue to apply as the post-development value for the development or irreplaceable habitats has not been affected.
However, if the section 73 permission affect the post-development value of the phased development’s onsite habitat or its irreplaceable habitats, a new Overall Plan would be required to be submitted and approved to ensure the biodiversity gain objective will be achieved.
The content and approval matters for this Overall Plan are similar to that of an Overall Plan for the original planning permission, except that additional information must be provided in the Overall Plan about the post-development biodiversity value of the onsite habitat of a phase which has already begun and the planning authority must be satisfied that this value is at least the value of specified in the Phase Plan most recently approved for that phase (unless there has been a section 73 permission which has affected this value.)
