Environmental Impact Assessment
Our Environment team provide environmental consultancy services to deliver sustainable and viable solutions to planning and environmental problems.
Our environment team delivers sustainable, viable solutions to planning and environmental challenges. Working alongside our planning and transport teams, advising on everything from early feasibility to large-scale developments and Nationally Significant Infrastructure Projects. Early, pre-planning advice means environmental issues are identified from the start, so your proposals are environmentally sound before they are submitted.
As a registered participant in ISEP’s (Institute of Sustainability and Environmental Professionals) EIA Quality Mark scheme, we have demonstrated our ability to consistently produce high-quality Environmental Statements and our commitment to excellence in environmental impact assessment. This provides Local Planning Authorities and regulatory bodies with clear evidence of our competence in preparing Environmental Statements, as required under the EIA Regulations.
Our environmental services
Our environment planning services include:
- Environmental constraints and opportunities assessment: early identification of sensitivities, risks and design drivers
- Feasibility and site selection appraisal: comparing the environmental suitability of alternative sites
- EIA screening and scoping: determining whether a project counts as EIA development and, where it does, defining the scope, key issues, receptors and assessment methods
- Baseline data strategy: identifying the data, surveys and monitoring a project needs
- Environmental Statements: full EIA management, coordinating every technical consultant so the Environmental Statement is consistent, technically robust and balanced
- GIS mapping: spatial analysis, constraints mapping and data visualisation
