Impact and risk assessment

Anticipating problems before they arise can save you a lot of trouble. Knowing your legal obligations and the risk to the environment is essential. Johns Associates takes a pro-active approach to understanding environmental risk and communicating it to the project team, client and regulator to minimise its impact.

The key to managing risk and impact effectively lies in covering all the bases from the outset:

  • Conducting effective surveys to understand the character of the environment
  • Appropriately using data and the right methods
  • Gaining community support
  • Liaising with regulators
  • Obtaining required permissions
  • Ensuring successful implementation on the ground

Determining how all of these can be achieved efficiently while making an overall positive impact with multiple benefits is our strength.

Our impact and risk assessment services range from high-level appraisals and topic specific analysis to detailed multi-disciplinary Environmental Impact Assessment (EIA), Sustainability Appraisals (SA) and Strategic Environmental Appraisals (SEA). We also undertake other risk-based work including Flood Risk Assessments, COMAH Environmental Assessment Reports, Environmental Permits, Waste Exemptions and CL:aire to name but a few.

The team can lead your risk or impact assessment, cover the full spectrum of potential issues, carry out community consultation and design and produce supporting drawings, graphics and documents. Or we can simply take a supporting technical role (e.g. ecologists, hydrologists, landscape architects) if that’s what is needed.

Johns Associates is a Corporate Member of IEMA and maintains up to date planning case law information to ensure our advice is always leading-edge. Our impact and risk assessment specialists work hand in hand with our in-house planners or with other planning professionals.

Johns Associates’ proven sustainability credentials, coupled with technical excellence, a passion for success and sound business understanding will bring success to every aspect of your project.
