Flood Risk Assessment
At Courous, we specialise in providing comprehensive Flood Risk Assessments (FRA) and Drainage Strategies tailored for planning applications, new developments, and property improvement projects. Based in Lancashire and serving clients across the UK, our consultant-led solutions help developers, landowners, and local authorities mitigate flood risk, ensuring regulatory compliance and safeguarding communities.
Why Flood Risk Assessments Are Essential
Flooding can have devastating impacts on developments, businesses, and communities. A professionally prepared Flood Risk Assessment (FRA) is often a critical requirement for planning approval. It identifies site-specific flood risks from rivers, surface water, groundwater, sewers, and reservoirs, and proposes effective mitigation measures.
At Courous, our experienced consultants ensure your project is designed safely and sustainably - reducing flood risks today and protecting assets well into the future.
What Our Flood Risk Assessments Include
Detailed Site Appraisal
We review topographic surveys, hydrological data, historic flood maps, and EA Flood Zones to accurately determine your site's vulnerability and inform land use decisions, including land drainage requirements.
Climate Change Impact Assessment
Using the latest Environment Agency guidance, we evaluate how future climate scenarios could affect your flood risk and drainage capacity.
Mitigation Measures
Our strategies include recommendations for finished floor levels, flood resistance/resilience construction techniques, and Sustainable Drainage Systems (SuDS) such as swales, ponds, and soakaways. We also assess emergency access and egress to safeguard life and property.
Surface Water Management Strategy
We design site-specific SuDS systems — including permeable paving, green roofs, ponds, and underground storage — to manage rainfall on-site and reduce runoff.
Drainage Strategy
A complete drainage strategy accompanies every FRA, including conceptual layouts, discharge options, and hydraulic calculations. We explore all discharge methods in line with the drainage hierarchy, such as infiltration, land drainage, watercourses, or sewer connections.
