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 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, we 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.

Climate Change Impact Assessment
Using the latest Environment Agency guidance, we evaluate how future climate scenarios could affect your flood risk.

Mitigation Measures
Our strategies include recommendations for finished floor levels, flood resistance/resilience construction techniques, sustainable drainage (SuDS), and emergency access/egress planning.

Surface Water Management Strategy
We design site-specific SuDS systems — including permeable surfaces, green roofs, swales, ponds, and underground attenuation — to manage rainfall on-site and minimise runoff.

Drainage Strategy
A full drainage strategy accompanies our FRA, showing conceptual layouts, discharge methods (following the preferred hierarchy), and supporting hydraulic calculations. Options such as infiltration, watercourse discharge, or connection to surface water sewers are explored in detail.ency, and drainage boards to secure approvals efficiently.
