Proposed plans
It is being proposed to strengthen and stabilise the structure to secure the Cobb’s long-term future. This may include construction of a low-level concrete toe foundation strengthening wall along with tension piles to anchor the inner harbour walls.
Design options on concrete toe walls and/or rock armour (rock armour for the outer harbour wall) are being extensively reviewed by the project team and wider statutory authorities, including Historic England, Marine Management Organisation, and the Environment Agency.
The project team is currently looking at feasible options, with the goal of choosing a design that can be presented to stakeholders and the public for feedback. Once the choice of design has been finalised, the project team will draw up a timeline for completion and be able to comment further on the works.
Grade 1 listed Cobb heritage preservation
The project team are working closely with heritage and conservation organisations including Historic England & Dorset Council’s Conservation team to maintain the historical integrity of the Cobb. This will ensure plans, which will require listed building consent, are sensitive to the inherent historical and cultural quality of the harbour.
Environmental considerations
The project team are working closely with environmental organisations including the Environment Agency, the Marine Management Organisation & Natural England to ensure that the project protects existing habitats (as far as reasonably practical) and has a positive impact on biodiversity gain.
Consultation
Dorset Coast Forum (DCF) will lead on the wider public, community and commercial engagement; ensuring that key user groups are consulted to mitigate any adverse impacts. Two events have been held already with the commercial users of the Cobb, and wider community-level events and activities will take place in due course with updates on this webpage. These may include public consultation meetings and/or pop-up events on the Cobb, including a heritage walk.
