Environmental Impact Assessment (EIA) is a process by which the potential beneficial and adverse environmental effects of a proposed development are determined. The effects are determined through a review of baseline conditions measured against predicted results using test cases or modelled results based upon available data.
The environment, as defined by the EIA European Commission Directive, consists of the physcial environment and the social and economic aspects.
Where an EIA is required for a particular development, this involves the production of supporting assessments and/or technical chapters for a range of disciplines, as agreed via a scoping exercise. These cover a varierty of topics, such as Flood Risk, Drainage & Hydrology, Transport Planning, Ground Conditions, Heritage and Socio-economics. The assessment and chapters are compiled into an Environmental Statement (ES).
In addition to the main body of the ES, BWB produce a Non-Technical Summary (NTS) which outlines the results of the EIA process and the potential effects in terms accessable to the wider public.
