Avonmouth Docks & Lamplighter’s Marsh

Current status

We are carrying out surveys around the docks to identify existing services before we start work on the new flood defence walls in 2022.

Work planned

Throughout the Avonmouth docks area we will be installing various flood defences which include sheet piled walls, precast concrete walls, insitu concrete walls and earth flood embankment.

To the north of the area at Chittening Warth we will be constructing an earth flood embankment. To the south of the area at Lamplighters Marsh we will be installing a small earth flood embankment which will tie into a precast concrete flood defence wall beneath the M5 River Avon bridge. Improvements will also be made to Mitchells Salt Outfall, Holes Mouth Outfall and Kings Weston Outfall structures which will stop tidal water entering into the local watercourses.


The project will reduce flood risk to businesses, homes and infrastructure from flooding, and enable development, in this important Avonmouth and Severnside Enterprise Area, helping unlock 12,000 new jobs by 2026 and boosting the regional and national economy.
Pedestrian access will be maintained into Lamplighter’s Marsh so that the area can continue to be enjoyed.
