Flood Risk Assessments (FRA)
A Flood Risk Assessment (FRA) is a key part of the planning process for developments in areas affected by flood risk, surface water flooding, river flooding, or other sources of flooding. An FRA can help support planning applications, identify site constraints, and show how flood risk will be safely managed.
Whether you are building a new home, creating a house extension, converting a property, or developing a small residential site, a professional flood risk assessment may be required by the local planning authority. This is especially important where development is proposed in Flood Zone 2, Flood Zone 3, or in areas with known surface water flood risk.
A well-prepared FRA can help with supporting a planning application, Identifying potential flooding risks, demonstrating safe site drainage, protecting property and future occupants, meeting local authority and Environment Agency requirements.
A typical Flood Risk Assessment considers Flood zones, surface water flood maps, site levels and topography, ground conditions, existing and proposed drainage arrangements, safe access, egress, and finished floor levels.
An FRA provides a clear and practical way to assess risk, improve site design, and support compliance. When prepared properly, it helps deliver safe, sustainable development while reducing the impact of flooding on people, property, and infrastructure.
Flood Risk Assessment
Flood Risk Assessments (FRAs) are essential technical evaluations designed to identify the likelihood of flooding and its potential impact on a specific site or development. In an era of increasingly volatile weather patterns, an FRA serves as a proactive blueprint for safety, ensuring that new projects are not only resilient themselves but do not inadvertently increase the flood risk for surrounding communities
