Decision
Decision: CONFIRMING THE DECISION TO VARY THE S106 AGREEMENT MADE UNDER:
Section 106 of the Town and Country Planning Act 1990 (as amended), relating to:
- The Ferals BNG habitat bank.
Decision:
To vary the s.106 agreement to secure biodiversity units at the Ferals BNG habitat bank.
Background:
As part of our responsibilities as the responsible body for biodiversity net gain (BNG) Dorset Council is working with third party landowners to secure habitat banks which are suitable for inclusion on the national biodiversity gain sites register. Once a site has been selected it is necessary to enter into a legal agreement under Section 106 of the Town and Country Planning Act 1990 to provide the necessary certainty of securing habitat units from landowners which can then be used to provide off-site BNG where developers are unable to secure this on site. This will then enable the habitat bank to be included on the national sites register. If requested by the site manager, Dorset Council can vary the s106 legal agreement at a later date to allow change to the number and type of units made available to enable development, to ensure that the type of unit is appropriate to site conditions and to the units required by development.
The delegated decision confirms Dorset Council’s agreement that the legal agreement for the Ferals can be varied via preparation and sealing of a deed of variation, to enable the number and type of units provided to be changed.
Reasons for the decision
Enabling the deed of variation will ensure Dorset Council helps provide an appropriate bank of BNG units for developers to use, thereby facilitating development.
Under the officer scheme of delegation and relevant nomination, I am authorized to approve the selection of these sites and to instruct the preparation and sealing of the three s106 agreements.

(b) the total expenditure associated with any such contract /agreement does not exceed the applicable levels set out in Appendix 2 of the Officer Scheme of Delegations; and
(c) the process followed is in accordance with the Contract Procedure Rules.
Alternative options considered
If the council does not authorize this deed of variation, the habitat bank will not be able to provide the optimum mix of BNG units required by developers.
