Flood risk

Our highly specialist and experienced team helps clients to unlock development potential by appraising, managing and reducing flood risk.

Our application of cutting-edge ISIS/TUFLOW modelling technology in combination with a range of geographic information system (GIS) tools enables us to significantly refine site-specific flood zones. It also helps ensure we can manage and mitigate impacts further afield.

The early engagement of our team in the development process is the key to success. Through the application of these modelling techniques, we work with developers to tackle flood risk issues and explore the implications and costs of proposed mitigation measures. This is critical to ensure development is appropriate to the site and to maximise the likelihood of approval.

Undertaking this work before incurring costs for work associated with preliminary design is crucial to determining the viability of any scheme.

Alongside identifying and managing existing issues, we incorporate potential future risks into our analyses, helping to ensure the work undertaken is sustainable, and the best possible return on investment.

Who we work with

We work with national house builders, large energy and utility service providers, commercial developers, public bodies, local authorities and private individuals – the list is wide and varied.

All projects demand high-level technical discussions and negotiations with the Environment Agency and local authorities, informed by our own extensive understanding of existing and developing legislation.

Stakeholder engagement

We have excellent relationships with the Environment Agency and local authorities and regularly present our findings, thoughts and suggestions to regulators and community bodies, listening to concerns and providing empathetic and reasoned responses to help achieve outcomes that work for all.

Our use of cutting-edge modelling techniques is designed to promote informed, safe and practical decision-making. However, flood risk is a highly emotive subject and land development is always subjective - support of clients in stakeholder engagement is crucial.

Our flood risk services

From a planning perspective, we deliver:

  • Site-specific flood risk assessments
  • Assessment of existing and post-development storm water run-off rates
  • Drainage strategy development
  • Site-specific refinement of flood zonation maps

From a design perspective, we deliver:

  • Optimisation of site layout from a flood risk perspective
  • Determination of minimum finished floor levels
  • Advice on flood resistance and resilience measures, and protection
  • Storm water drainage design

In addition, we also provide expert witness services at planning appeal stage.
