Case Study
Flood Risk Assessments and NAFRA2 Compliance
As flood risk guidance and mapping continue to evolve, understanding the implications for development sites has become increasingly important. The introduction of NAFRA2 has brought significant changes to the way flood risk is assessed across the UK, providing more detailed modelling and updated climate projections that can directly influence planning decisions and site viability.
This case study highlights how our Civils team supports developers, planners, and landowners in navigating these changes. By combining technical expertise with the latest flood risk data, we help clients identify potential constraints early, develop practical mitigation measures, and progress projects with greater confidence through the planning process.
OUR ROLE
Our Civils team works closely with developers, planners and landowners to assess flood risk and provide practical, site-specific guidance throughout the planning and development process.
By utilising the latest NAFRA2 datasets and emerging guidance, we help clients understand how flood risk affects their sites and provide comprehensive Flood Risk Assessments, early-stage risk screening and tailored mitigation strategies to support successful project outcomes.
Challenges
The introduction of NAFRA2 is increasing the level of scrutiny applied to development sites across the UK. More detailed flood modelling and updated climate projections mean that sites previously considered suitable for development may now be subject to additional planning requirements, design constraints or mitigation measures.
Without a clear understanding of these evolving flood risk classifications, developers can face planning delays, unexpected project costs and uncertainty regarding the viability of proposed schemes. Navigating the changing guidance and assessment criteria requires specialist technical expertise and an up-to-date understanding of the latest flood risk data.
SUCCESSES
Our team provides detailed, evidence-based Flood Risk Assessments that align with the latest NAFRA2 mapping and guidance. Through early-stage risk screening, we identify potential constraints at the outset of a project, allowing clients to make informed decisions before significant investment is made.
Where flood risks are identified, we develop practical and proportionate mitigation strategies that support planning requirements while maintaining project viability. By taking a proactive approach to flood risk management, we help clients minimise delays, reduce unforeseen costs, and deliver resilient developments prepared for future environmental challenges.
