Environmental Impact Assessment (EIA)

Contact: Hydrology@arcusconsulting.co.uk

The Arcus Hydrology team has extensive experience in undertaking EIAs for a variety of development types and works throughout the whole lifecycle of a project to ensure quality advice whilst maximising consentability for your development.

We understand all the stages required to deliver an EIA and we proactively work to agree appropriate scope of work with consultees such as the Environment Agency, Scottish Environment Protection Agency, SNH and Natural Resources Wales.

During the early stages of an EIA Arcus will obtain hydrology and geology data including:

  • Ground conditions at the Development
  • Downstream hydrological processes
  • Aquifer classification and vulnerability
  • Surface water quality
  • Public and private water supplies
  • Groundwater Dependent Terrestrial Ecosystems (GWDTEs)
  • Flooding
  • Contaminated land

Arcus provide input to the site design stage to allow adverse effects to be avoided where possible, through layout alterations or through the use of embedded mitigation measures to protect the water and geology environment.

Our EIA chapters are of the highest standard and our approach has withstood legal review on all hydrology EIA work undertaken by Arcus and has received positive feedback from consultees for proposing appropriate embedded mitigation on a project specific basis.

We produce the following technical appendices to support our EIA chapters:

  • Flood Risk Assessments
  • Flood Consequence Assessments
  • Private Water Supplies Risk Assessments
  • Water and Construction Management Plans
  • Watercourse Crossing Inventories
  • Mining Risk Assessments
  • Peat Slide Risk Assessments
  • Surface Water Monitoring Plans
  • Groundwater Monitoring Plans
  • Information to support Habitats Regulations Assessments
