Biodiversity Net Gain Supplementary Planning Document

Following public consultation the Council has now adopted a Supplementary Planning Document (SPD) on Biodiversity Net Gain. This SPD provides further guidance for developers, applicants and ecological consultants on how planning applications can satisfy the requirement for delivering Biodiversity Net Gain within Doncaster.

The adoption version of the Council’s Supplementary Planning Document on Biodiversity Net Gain and a Consultation Statement prepared in accordance with the requirements of the Town and Country Planning (Local Planning) (England) Regulations (2012), can be found below:

Since publication it has been noted that there is a small mistake in paragraph 3.1.2 of the document. River assessments are not needed for developments within 10m of the vast majority of ditches. An exception to this may be some heavily engineered ditches that act as part of the river system. The following sentence:

"Any development within 10m of the bank top of a river/stream/canal/ditch will need a river assessment"

Should read:

"Any development within 10m of the bank top of a river/stream/canal will need a river assessment."

Please note, the biodiversity offsetting contribution fee has been increased (10%) from 1 April 2023 in line with the Council's wider review of Fees and Charges for 2023/24 as part of the budget setting process. The biodiversity offsetting contribution fee is now therefore £27,500 per unit (or part thereof - i.e. if 0.5 units are required the fee would be £13,750). This supersedes the fee quoted in the SPD.

Further Information

Section 3.5 of the SPD provides temporary guidance on how to assign strategic significance in Biodiversity Metric Calculations. A Local Nature Recovery Strategy (LNRS) is being developed for South Yorkshire. Once this is completed this section of the Council’s website will be update with guidance on how the LNRS should be used to help determine strategic significance.

The Biodiversity Metric also requires strategic significance to be determined for rivers and streams, with either a ‘high’ or ‘low’ strategic significance being assigned in the Biodiversity Metric. If a habitat or river feature (present either pre or post development) can be considered to be helping towards the delivery of river restoration actions and objectives identified within the relevant River Basin Management Plan, Catchment Plan or Catchment Planning System then it should be given high strategic significance. In addition, how strategic significance is defined for rivers and streams may be updated in due course as the LNRS is developed and further information on that will be provided here in due course.
