Combined FRA and SuDS
SuDS and Flood Risk Combined
Combined Flood Risk Assessments and SuDS Solutions
Whilst SuDS and Flood Risk Management are not the same thing, they are often both required and a cost saving can be applied when getting one report that covers each condition. Sustainable drainage systems (SuDS) are designed to manage stormwater locally (as close its source as possible), to mimic natural drainage and encourage its infiltration, attenuation and passive treatment. With this in mind, the multi-functionality and multiple benefits of SuDS should always be considered. A flood risk assessment (FRA) is an evaluation of the potential risk of flooding for a specific area or development site. It considers various factors related to flooding and aims to provide guidance on managing flood risk.
We are helping clients achieve both compliance and cost efficiency with its combined Flood Risk Assessment (FRA) and Sustainable Drainage Systems (SuDS) solutions.
While SuDS and flood risk management serve different purposes, both are often required for planning and development projects. By commissioning a single, comprehensive report covering each condition, clients can benefit from valuable cost savings and a more streamlined process.
We assess the potential flood risks to your site from rivers, surface water, groundwater, and drainage infrastructure. Our reports are designed to satisfy planning conditions and help you achieve swift approval from local authorities and the Environment Agency. Each FRA report includes site-specific data, flood maps, and mitigation recommendations where required.
Alongside this, our SuDS reports offer low-impact, sustainable drainage strategies that reduce surface water runoff and align with national SuDS standards. These reports include recommendations for infiltration systems, attenuation storage, or discharge to watercourses, depending on your site conditions.
With a strong understanding of UK planning policies and drainage requirements, our team works to provide solutions that are both environmentally sound and cost-effective.
Importance of Flood Risk and SuDS
Integrating Flood Risk Assessments (FRA) with Sustainable Drainage Systems (SuDS) is the gold standard for climate-resilient development and modern water management. While an FRA identifies the specific vulnerabilities of a site—analysing potential threats from river, coastal, and surface water flooding—the implementation of SuDS provides the physical solution to mitigate those identified risks.
