Nutrient Neutrality
The issue of nutrient pollution at Habitats Sites (formerly known as European sites) and the requirement for new development to achieve nutrient neutrality has been an issue which Local Planning Authorities (LPAs) have been grappling with since 2019 in areas such as the Solent region, Herefordshire, Somerset, Cornwall and Kent.
In March 2022, the Department for Levelling Up, Housing and Communities (DLUHC) issued nutrient pollution advice to a further 42 LPAs. In light of this advice, where a Habitats Site has been identified to have an ‘unfavourable conservation status’, any additional nutrient loads, such as from new development, may have an adverse effect. Therefore, in order to meet the requirements of the Conservation of Species and Habitats Regulations 2017 (as amended), new development must consider adequate mitigation through an appropriate assessment, to achieve nutrient neutrality.
Alongside the DLUHC’s advice, Natural England provided LPAs a package of tools including maps of the affected catchments, details of the affected sites, a national Nutrient Neutrality Methodology, and site-specific evidence documents and nutrient calculators to assess the nutrient loads from development proposals. This includes revised advice and methods for calculating impacts for current LPAs. LPAs are now looking at how this advice can be taken into consideration in land use planning (including 5-year housing supply, planning policy requirements and strategic mitigation solutions) as well as in development management/control.
Lepus has experience of dealing with nutrient neutrality of land use plans through Habitats Regulations Assessment and Sustainability Appraisal, providing advice on policy wording and the scope and scale of development.
