Do you need an Environmental Impact Assessment (EIA) in Hampshire?
If your development could significantly affect land, wildlife, water, or landscapes, the council will expect formal ecological evidence in Hampshire before it can be approved. Environmental Impact Assessments (EIA) in Hampshire span to major housing, infrastructure, commercial and mixed-use developments.Â
Where an EIA applies, a planning application in Hampshire cannot progress without a legally compliant ecology assessment in place.
Hampshire’s landscape contains several features that frequently elevate EIA risk:Â
• The Solent coastline from Lymington to Portsmouth — internationally designated bird habitat driving severe impact and mitigation thresholds
• The New Forest National Park fringe around Lyndhurst and Ringwood — protected heathland and ancient woodland buffers affecting development scale
• The River Test, Itchen and Alre floodplains — SAC river systems with strict hydrological and pollution controls
• South Downs chalk landscapes near Winchester and Petersfield — priority grassland and groundwater-sensitive catchments
• Strategic motorway and rail corridors around Basingstoke and Eastleigh — cumulative ecological effects from staged infrastructure growthÂ
These conditions regularly underpin EIA screening and scoping decisions.Â
Our Environmental Impact Assessment services support all Hampshire Local Planning Authorities, delivering precise ecological data to ensure seamless application processing and regulatory compliance.
Why Planning Authorities Request an EIA in Hampshire
Hampshire local planning authorities (LPA) are obligated to consider the Wildlife & Countryside Act 1981, the Habitats Regulations, and the NERC Act 2006 in their decision-making process. LPAs use an Environmental Impact Assessment (EIA) to provide a comprehensive evaluation of all potential environmental impacts. These include ecological risks, such as evaluating protected species in Hampshire projects, to ensure a holistic understanding of a project’s implications.
Without a detailed EIA in Hampshire, applications risk delays due to incomplete environmental assessments, seasonal survey requirements, or additional conditions pending further evidence to address ecological concerns.

FAQ - Environmental Impact Assessments (EIA) in Hampshire
What is an Environmental Impact Assessment for developments in Hampshire?
An Environmental Impact Assessment is a process used to evaluate the likely environmental effects of a development before planning permission is granted. In Hampshire, this often applies to developments across coastal, urban, and rural areas where environmental sensitivity and planning constraints are high.
When is an EIA required for developments in Hampshire?
An EIA may be required where a development is likely to have significant environmental effects. In Hampshire, this can include large residential schemes, infrastructure projects, and developments in sensitive locations. A screening opinion from the Local Planning Authority will confirm whether an assessment is needed.
How does EIA apply to coastal developments in Hampshire?
Hampshire has an extensive coastline, meaning developments in these areas may require an Environmental Impact Assessment. Coastal schemes often need to consider impacts on habitats, flood risk, landscape, and the marine environment.
Can developments near national parks require an EIA?
Yes, developments located near or within national parks such as the South Downs National Park or New Forest National Park may require an EIA due to their environmental sensitivity. These areas are subject to stricter planning controls and require careful assessment.
What environmental factors are commonly assessed in Hampshire EIAs?
Typical factors include ecology, landscape and visual impact, transport, air quality, noise, water environment, and coastal or flood risk where relevant. The scope of the assessment depends on the development and location.
How does EIA consider ports and infrastructure in Hampshire?
Hampshire includes major ports and transport infrastructure. Developments in these areas may require an EIA to assess impacts on traffic, air quality, noise, and surrounding communities, particularly where large scale or strategic development is proposed.
What role does flood risk play in Hampshire EIAs?
Flood risk is a key consideration, particularly in coastal and low lying areas. An Environmental Impact Assessment may assess how a development interacts with flood risk and ensure that appropriate mitigation measures are in place.
What is included in an Environmental Statement for Hampshire developments?
An Environmental Statement includes detailed technical assessments, identifies potential environmental impacts, and outlines mitigation measures. It forms part of the planning application and supports the decision making process.
Which authorities manage EIA in Hampshire?
EIA and planning applications are managed by the relevant Local Planning Authority depending on the site location, alongside
Hampshire County Council

How can an EIA support planning success in Hampshire?
An Environmental Impact Assessment helps identify environmental constraints early, ensures appropriate surveys are completed, and provides clear evidence to support the planning application. This helps reduce risk, improve the quality of the submission, and support a smoother planning process.
