Flood Risk Assessment

ACCON UK is able to provide detailed Flood Risk Assessments for residential or commercial developments of any scale, nationwide. The susceptibility of land to flooding is an increasingly important consideration in determining planning applications; the potential consequences for occupiers, either of the development or elsewhere, in terms of safety and financial risk can be serious. Flood Risk Assessments (FRAs) vary from simple exercises for small or less vulnerable developments to detailed studies for more vulnerable or larger developments sometimes requiring quantitative approaches i.e. hydraulic modelling to determine the risk posed to the development. ACCON offer various levels of detail suited to your requirements including:

  • Scoping Reports;
  • Full Flood Risk Assessments (FRAs);
  • Strategies for Sustainable Urban Drainage System (SUDS);
  • Review of Flood Risk Assessments;
  • Strategic Flood Risk Assessments; and
  • Advice on planning applications in terms of flood risk.

ACCON are able to provide a variety of detailed reporting for flood risk assessments which depending on the precise requirements of our clients may include:

  • Pluvial and fluvial flood data.
  • Predicted flood depth data.
  • Susceptibility of groundwater identifying where geological conditions could enable groundwater flooding to occur and where groundwater may be in close proximity to the ground surface.
  • BGS geological indicators of flooding.
  • Flood return periods.
  • ‘Defended’ and ‘Undefended’ flood risk data
  • Detailed River Network features
  • Surface water run-off flood hazard, covering minor rivers, water flowing across the ground or raised groundwater levels etc.

Contaminated Land 

ACCON UK offers a comprehensive service in the field of contaminated land assessment, undertaking Phase 1, 2 and 3 investigations.

Phase 1 Desk Study: The Phase 1 desk study identifies any potential sources of contamination resulting from the current and historical activities at the site by reviewing available information from sources such as archives, plans and records, databases and information from regulatory authorities. In this way we can discover the past and current activities at a site and assess them for potentially contaminative processes, in order to determine the potential for the presence of contamination. The Phase 1 study also identifies any potentially sensitive receptors, e.g. humans, surface watercourses, aquifers, buildings or ecological receptors and also collates the information relating to the site’s environmental setting i.e. geology, hydrogeology, industrial activity, location of controlled waters, pollution incidents and proximity to open/closed landfill sites. This information is then used to undertake a qualitative Risk Assessment through the development of a conceptual model for the site. The conceptual model identifies any Significant Pollutant Linkages which may be present. If Significant Pollutant Linkages are present then a Phase 2 site investigation may be required to quantify the risk and also to assess the potential for environmental liability associated with the site.

Phase 2 Site Investigation: An intrusive site investigation is undertaken to investigate each aspect highlighted by the Phase 1 desk study. The Phase 2 investigation is designed and implemented using a variety of in-situ exploratory methods, size of site and type of contaminants identified by the desk study as potentially present.

Phase 3 Remediation: If remediation is required following the Phase 2 works, then a site specific remediation methodology can be produced; this involves consultation with the regulatory authorities to ensure satisfactory design and implementation of the remediation programme.


ACCON UK is able to undertake Sustainability Appraisals for proposed developments of any size. In terms of land use planning, a Sustainability Appraisal is similar to Strategic Environmental Assessment (SEA) but also includes economic and social inputs, and provides a critical evaluation of the performance of a proposed project against predetermined social, economic and environmental criteria so that the project’s performance can be improved. Sustainability Appraisals are mandatory under the Planning and Compulsory Purchase Act 2004. At present there is no specific formal procedure when undertaking a Sustainability Appraisal, however it usually involves the following aspects:

  • Reviewing current best practice with regard to the subject of the plan;
  • Scoping national, regional and local policy guidance;
  • Reviewing the plan’s assumptions, objectives and forecasts;
  • Identifying criteria for appraising the plan’s sustainability performance;
  • Modifying plans/policies in the light of the appraisal; and
  • Identifying sustainable development indicators so the plan’s long term delivery of sustainability can be monitored.

Sustainability Appraisal has the advantage of being quicker than SEA, producing a slightly less rigorous, although still valuable, broad analysis, usually in the form of a checklist with accompanying explanation. This allows fairly rapid assessment to be made about the sustainability impact of a planned development, individual policies and also indicates where policy adjustments may need to be made. Our sustainability credentials run through much of the work we provide in other specialist technical disciplines and in this respect we are able to provide advice on the following:

  • Renewable Energy;
  • Code for Sustainable Homes;
  • Carbon Footprinting and Management; and
  • Water & Waste Management.


Graham Parry has been involved in the Civil Engineering Sustainability Assessment, Rating and Awards Scheme (CEEQUAL) since its very earliest stages. He is now one of a very small number of jointly qualified Assessors and Verifiers for the scheme and has been a member of the Technical Advisory Group. CEEQUAL includes environmental aspects such as water use, energy, landscape, noise, dust, archaeology, waste minimisation and management, and community amenity. Awards are made to projects in which the clients, designers and constructors have gone beyond the legal and environmental minima, to achieve distinctive standards of performance. Recently, Graham has been involved in the following CEEQUAL projects:

  • Lee Valley White Water Canoeing Centre (Olympics)
  • A419 Blundon Bypass
  • Hammersmith Depot Remodelling
  • Multi Storey Car Park (Olympics)
  • M25 Term Contract (Pilot)
  • Cross Valley Link Road
  • East London Line
  • Orient Way Carriage Sidings Depot
  • Axbridge Raw Waste Water Treatment Works
