Protecting people and wildlife along the Severn Estuary

The Severn Estuary between south-west England and south Wales has one of the highest tidal ranges in the world. Storm surges and large waves are common, putting coastal homes and businesses at risk of flooding. Forecast sea level rises, due to climate change, will exacerbate the flood threat. The Avonmouth Severnside Enterprise Area (ASEA) ecology mitigation and flood defence project will provide flood protection for local communities and industries for the next 60 years, while enhancing natural habitats. The scheme will deliver improved defences along 17km of eastern coastline, from Lamplighters Marsh in Bristol to Aust in South Gloucestershire, helping to reduce flood risk for least 2500 homes and businesses and unlock ASEA’s economic potential – potentially delivering 12,000 new jobs for local communities by 2026. We are working for Bristol City and South Gloucestershire councils and the Environment Agency in a joint venture with civil engineering contractor BAM Nuttall (BMMJV) on the detailed design and construction of flood defences and wetland areas. The scheme will provide environmental mitigation with the creation of at least 80ha – the equivalent of around 112 football pitches – of wetland habitat for overwintering birds. The work will make it easier for people to enjoy nature too, as it includes improvement to walking routes and a new viewing area at Severn Beach offering spectacular vistas across the estuary. It’s an initiative that will encourage leisure activity while improving wellbeing for local residents and visitors.
