Arun’s BNG level is set at 10%.

The NPPF states: "applicants are encouraged to consider biodiversity net gain early in the development process and factor it into site selection and design. Where appropriate, they should discuss the biodiversity net gain requirements for their development upfront with the relevant local planning authority utilising any pre-application advice services offered by them. This could help establish whether development proposals would be subject to biodiversity net gain and, if they are, enable feedback on the proposed strategy for achieving the biodiversity gain objective and consideration of the Biodiversity Gain Hierarchy to inform the design of the proposals"

Please note, If you work for the LPA and wish to add additional information, please inform the Joe's Blooms team here.

Arun’s pre-application advice service can be foundhere.

Specific BNG Requirements are set out in the BNG Page.

Biodiversity Net Gain (BNG) is an approach to development that requires developments to be designed and planned in ways that leave the natural environment in a measurably better state than prior to development.

BNG is already required under policy ENV DM5 of the Arun Local Plan which states all development schemes should, in the first instance, seek to achieve a net gain in biodiversity and protect existing habitats on site.

The Environment Act 2021 goes further and from 12 February 2024 it is a mandatory requirement for all major development (with a few exemptions) to deliver a net gain of at least 10%. Habitat management and monitoring must be secured for at least 30 years.
