Project Overview

Why does this project need to happen?

Sea-floor erosion, combined with the localised movement of stone blocks due to wave impact on the outer harbour wall and the deterioration of the structure on the inner harbour wall, have caused significant destabilisation of the structure.

It is predicted that the functionality of the Cobb as a breakwater would end in the 2040s, potentially resulting in the loss of the harbour, and over 100 residential and non-residential properties will be at increased risk of flooding and coastal erosion.

What works are planned for this project? 

The project aims to stabilise the Cobb to maintain its status as a breakwater, a coastal flood and erosion defence, and a safe harbour for many different types of vessels and businesses. It is being proposed to strengthen and stabilise the structure which may include construction of a low-level concrete toe foundation strengthening wall along with tension rods.

The project team are currently reviewing the scheme design options and a preferred option will be presented to stakeholders and the public.  The choice of preferred design will be posted on this webpage and there will be an opportunity to consult with the project team during engagement events in due course, details of which will be posted on this webpage.
