A Habitats Regulations Assessment (HRA) evaluates whether a proposed development could negatively impact protected sites such as Special Areas of Conservation (SACs), Special Protection Areas (SPAs), and Ramsar sites, which are safeguarded under the EU Habitats and Birds Directives.

When is an HRA Needed?

A HRA is necessary when a development may affect protected habitats or species within designated conservation areas, common triggers can include:

⦁ Adding housing units near sensitive sites

⦁ Increasing visitor numbers, leading to habitat disturbance

⦁ Potential pollution from discharges or changes to local water quality

⦁ Construction noise or lighting

Key Stages of the HRA process

Screening

We begin by screening for any ‘likely significant effects’ on nearby protected sites. Small
projects can often be scoped out here if no risks are identified. If potential impacts are noted, we proceed with further assessment.

Appropriate Assessment (AA)
At this stage, we provide a detailed evaluation of each identified risk and develop a
mitigation strategy to prevent adverse impacts on the protected site. This evidence, along with any necessary long-term management and maintenance plans, including funding
requirements, is submitted for consideration by the Local Planning Authority (LPA).

Assessment of Alternatives

If potential impacts remain, we explore alternative solutions, such as changing the scale or
location of the project, to minimise risks to nearby protected habitats.

Imperative Reasons of Overriding Public Interest (IROPI)

If no feasible alternatives exist, the development may only proceed if it serves an imperative reason of overriding public interest, such as public health, public safety, or beneficial consequences of primary importance to the environment.
