Integration with Flood Risk Assessments

The Hounslow drainage form is often a key component of a wider Flood Risk Assessment (FRA). It requires precise data regarding greenfield runoff rates and attenuation volumes to ensure that the development does not increase flood risk elsewhere in the borough. Our consultancy offers over 15 years of experience in delivering these technical reports to satisfy lead local flood authorities (LLFA) across Greater London.

Whether you are dealing with minor residential extensions or major commercial developments, ensuring your drainage strategy is robust from the outset is essential to avoid planning delays. By combining this assessment with other environmental reports, such as Environmental Impact Assessments (EIA), SWEL provides a comprehensive path to planning approval.
