Langstone Coastal Defence Study


Thank you for your responses to the latest questionnaire regarding the options along the Royal Oak frontage, we had over 100 responses. We are busy pulling these together and will produce a summary in due course which will be shared on this page.

In the meantime we will be using your responses to inform a cabinet paper which will be taken to Havant Borough Council’s Cabinet who will make the decision with regards to the next stages of the project. Your views will be taken into consideration in the paper, along with the view of the regulators (Natural England, Historic England, Chichester Harbour Conservancy, the Environment Agency, Havant Borough Council (HBC) Local Planning Authority, HBC Conservation Officer) and frontline residents and businesses.

Cabinet will determine the next stages of the project on 2nd September 2020.

In January 2020 we held two public events where we shared the leading defence options for Langstone with you. In March 2020 we also held a collaborative workshop with members of the community and residents to revisit and discuss the drivers for a scheme and to explore the coastal defence options for Langstone.

YOU SAID...Feedback from these events clearly showed that a key concern was the seawall option along the Royal Oak frontage in the core scheme. Concerns you raised related to impacts on views and heritage associated with a higher flood wall along this frontage. You also talked about an alternative option of reinforcing the quay while accepting some flooding in the future but with increased resilience of properties.

WE DID... We have taken your concerns on board and have revisited options for this section of the core scheme. We have listened to you, and as a result, have identified two further options for the Royal Oak frontage incorporating an alternative defence alignment. Our consultants AECOM have spent time appraising the feasibility of this alternative alignment, and in June 2020, we sought your views.

The three options we asked you to consider were:

(A) The current leading option of a raised seawall.

(B) An alternative defence alignment with a floodwall between properties north of Langstone High Street, with no works to the Royal Oak frontage.

(C) An alternative defence alignment with a floodwall between properties north of Langstone High Street and replace the quay along the Royal Oak frontage.

We encourage you to look at the three different alignment options presented for the Royal Oak frontage 

Your views are important and will be taken into consideration, along with the views of the regulators, Natural England, Historic England, Chichester Harbour Conservancy, the Environment Agency, Havant Borough Council (HBC) Local Planning Authority, HBC Conservation Officer, frontline residents and businesses, when making a final recommendation to HBC on the route alignment to progress to the next ‘detailed design’ stage of the project.

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, the Eastern Solent Coastal Partnership (ESCP) 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 the ESCP 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.

Further information about Langstone Harbour's environmental importance can be found here and information about Chichester Harbour's environmental importance can be found here 


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.

What does the Study area cover?

The Langstone study frontage extends from the east bank of the Langbrook Stream west, to the A3023, and from the west of the A3023 to northeast extent of the Mill Pond.

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

Area 1-red: Mill Lane                                                      Area 2-blue: Langstone Sailing Club and Langstone Spit


Area 3-green: Langstone Village                                      Area 4-orange: The Old Mill and Mill Pond

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.

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 2020.
