Langstone Coastal Defence Study

Havant Borough Council (HBC) are undertaking a feasibility study to appraise options and develop outline designs for future coastal management at Langstone to reduce coastal flood and erosion risk to over 100 properties, as well as critical infrastructure including the A3023, the only road access to Hayling Island.

In March 2018, Coastal Partners on behalf of HBC, secured £376,000 of funding made up from Regional Flood and Coastal Committee Levy and HBC Community Infrastructure Levy to progress the Study and outline design of options at Langstone.

In May 2018 Coastal Partners commissioned AECOM, a well renowned multinational engineering consultancy. to provide professional services to deliver the Langstone Study and Outline Designs.

Where is the study area?

The ~1km long Langstone frontage is located on the mainland immediately north of Hayling Island, in the Borough of Havant, Hampshire.

The village of Langstone is bordered to the east and west by Langstone and Chichester Harbours which are sensitive sites, designated environmentally at a Local, National and International level.

The frontage is popular with locals and tourists due to its unique setting and is an important area for cultural heritage, with eight listed buildings, two Conservation Areas; Langstone Conservation Area and Mill Lane Conservation Area and the historic Wadeway from Langstone to Hayling Island.

For appraisal purposes the frontage has been broken down into 4 discrete units to facilitate the development of options. These are:

Please note that these visualisations are purely examples and should not be taken literally at this stage as the options will not be determined fully until the next stage of the project. Whilst the principles of the scheme have been defined, following the technical guidance which governs our industry, there is at least another 2 years for these options to be refined, adapted and if necessary, changed through the detailed design process. This includes how they will look and feel with strong consideration of community views but of course within the wholly appropriate constraints of our regulators Natural England, Historic England, Chichester Harbour Conservancy and the Local Planning Authority.

Next Steps?

The project team will continue to identify additional funding contributions towards the scheme. The detailed design stages of the project are likely to begin in 2021.

In January 2020, two public exhibitions were held to share and gain feedback on the leading options for reducing flood and erosion risk at Langstone. Over 200 people attended the events and 90 questionnaires were returned. From discussions with residents at the events and feedback from the questionnaires, it was clear that there were polarised views on some of the leading options and that some residents didn’t feel heard.

Following on from the public events, a collaborative stakeholder workshop was held on the 9th March 2020, with over 30 Langstone residents and local community stakeholders, to help address, listen to and understand their concerns and find a way forward by working together. Objectives and drivers for a scheme were explored and coastal defence approaches for Langstone discussed as a community. The workshop was welcomed by the community and feedback has been very positive.  

Two presentations were given at the workshop. 

Future Engagement

Following the public engagement events in January 2020, engagement with the stakeholder working group, residents, landowners, public and regulators will need to continue to ensure the project arrives at the best outcome. The detailed design stage of the project is likely to take 18-24 months, during which further significant engagement on the options will need to take place for them to be refined, adapted and if necessary, changed through the detailed design process. Changes could include exact alignments and how they will look and feel with strong consideration of community views but of course within the wholly appropriate constraints of our regulators Natural England, Historic England, Chichester Harbour Conservancy and the Local Planning Authority.

Engagement Timeline

What stage are we at now?

We are currently at the leading option stage of the project and development of outline designs. Leading options have been shared with local residents, businesses and landowners during a period of targeted engagement in the summer. This period concluded with a Key Stakeholder Working Group Meeting at the end of June. More details on the option development process can be found using the ‘How we’ve developed options’ link above.

Following this engagement, the project team have developed outline design drawings for the leading options, along with some visualisations to provide you with an idea of what some of the approaches could look like.
