EcIA – Ecological Impact Assessment


Ecological Impact Assessments (EcIA) may be produced for two purposes: either for sites where protected species surveys have been undertaken in addition to the Preliminary Ecological Appraisal, or for sites requiring a formal Environmental Impact Assessment (EIA).

If a project meets the necessary criteria for formal EIA, part of this will be dedicated to ecology and the natural environment, and is referred to as an EcIA.

We have thirty years’ experience producing impact assessment reports and work to the latest guidelines from CIEEM.

The report consolidates the results of several surveys such as Phase 1 Habitat surveys, dormouse, reptile and breeding bird surveys. Reports include in-depth analysis of the potential impacts of works upon valued habitats and species. This is used by planners and other consultees to assess whether the project should be given planning permission.

CEC can also provide input to screening and scoping documents for EIA and can undertake the Landscape and Visual Impact Assessment for EIA.

Where developments are proposed close to European Sites (e.g. Special Area for Conservation and Special Protection Areas), CEC can complete Habitat Regulations Assessments for your project.

A30 Chiverton to Carland Cross, Regional Delivery Partnership
CEC provided the construction phase ecological elements of the £300m Carland Cross to Chiverton Cross duelling. We were really impressed with the experience of the ecologists on the project, including large teams of Ecological Clerks of Works. CEC also helped us deliver various ecological enhancements like mammal passes and a bat house to help mitigate for the impacts of the road scheme and we found their expertise and flexibility on a scheme of this size invaluable.
