Seafront floodgates and sea wall strengthening included in £12million Exmouth tidal defence submitted plans
PUBLISHED: 12:28 02 October 2018
Plans have been submitted to install seafront floodgates and strengthen Exmouth’s seawall as part of a £12m tidal defence scheme aim to protect homes and businesses.
The Environment Agency is working with East Devon District Council to cut the risk of flooding to more than 1,400 homes and 400 businesses in Exmouth.
An application has been submitted to East Devon District Council, and if granted, work will begin in early 2019 and completed by 2021.
The submitted plans include:
• Flood embankments and walls between Withycombe Brook and the Imperial recreation ground.
• Raised defences between the Imperial recreation ground and Camperdown Terrace.
• Strengthening the existing seawall, improving drainage for water to drain back out to sea, floodgates between the Imperial Hotel and Premier Inn, and at The Grove pub, and new set back defences along the landward side of the Esplanade.
The tidal defence scheme would focus on three areas:
• Area A – on the estuary side of Exmouth; involves raising flood defences between the outfall of the Withycombe Brook and the Imperial recreation ground, and building a wall to reduce flood risk
• Area B – around the ‘gut’ at Campderdown; there will be raised defences between the Imperial recreation ground and Camperdown Terrace.
• Area C – involves the seafront, including the Esplanade from Mamhead slipway in the west, to between the clock tower and Premier Inn to the east; works will include strengthening the existing seawall, and new set back defences along the landward side of the Esplanade - meaning areas of the Esplanade and highway will still be inundated during storms, but floodwater will be stopped from flowing down nearby roads by the new defences.
The application states: “This application seeks to reduce the risk of damage due to flooding through the construction of new flood walls, ground raising, floodgates, and resilience measures.”
The application says the £12m scheme will reduce the flood risk from four per cent chance of flooding in any year, to one-in-200-a-year (0.5 per cent).
Also proposed are strengthening works, insertion of drainage holes, installation of square plates and works associated with installation of floodgates and posts to the Exmouth Sea Wall.
