Presentation and team work with States of Jersey and ESCP

States of Jersey visit the ESCPWe hosted a workshop with colleagues from the States of Jersey and their consultant AECOM to discuss common themes regarding coastal risk, policy, public engagement and asset management. The workshop provided an opportunity to explain our collaborative approach and show case recent communication event materials we prepared. The event was well received with Lisette Jones, Project Officer, States of Jersey commented that: “It was inspiring to hear about the level of collaboration that you have managed to achieve and the general feeling of positivity surrounding your work.”

We all look forward to future knowledge sharing events with the States of Jersey and other Risk Management Authorities, to share our vision, successes and passion.

The final stages of major concrete work have commenced with the pouring of the sloped concrete revetment located by Portsbridge Roundabout. This will finish the 1850m long reinforced concrete sea defence which spans along Tipner Lake. Other major work consists of the instalment of the rock revetment, which will be placed within the northern section of the site between the Northern Slipway and the sloped concrete revetment highlighted above.

Landward work at Tipner include the continuation of the pedestrian pathway linking the beginning of the Hilsea Lines to Hilsea Lido. Landscaping works continue to develop including reinstatement works at Alexandra Park. The non-established soil at Alexandra Park has been broken down and will be reprofiled to create a flat and smooth surface. The area will then be seeded and maintained until complete reinstatement with the rest of the field.

Phase 3 - Tipner Lake Update Phase 4 - Eastern Road - All going to plan for North Portsea Coastal Defences

Work could soon begin on the next phase of the North Portsea Island Coastal Defences Scheme, now that the planning application for road raising landward of Kendall’s Wharf has been submitted for approval. The planning application for Eastern Road seawall construction is programmed for submission in June 2019.

Phase 4 of the scheme focuses on the construction of a seawall

Plans to provide new flood defences for the Southsea seafront continue to progress with the tender for detailed engineering designs now underway. The successful consultant will further refine and add detail to the coastal defence principal designs so construction can begin in 2020. The Scheme, which will span 4.5km of Solent coastline from Old Portsmouth to Eastney, will protect more than 8,000 properties and 700 businesses from the risk of coastal flooding.

The tender to deliver detailed engineering designs has been communicated to seven consultancies, all of whom sit on the Flood and Coastal Erosion Risk Management Consultancy Services Framework. This framework was set up in 2016 to ensure greater consistency from a list of multi-disciplined consultancies that have both the expertise and resources to undertake a project of this scale. The procurement process opened on 3rd April with bids required for review by mid-May. The selected designer will then be appointed in June 2019.

along Eastern Road and raising the road at Kendall’s Wharf. Subject to planning approval, work on the road raising could begin in September with a view to being completed a year later.

The seawall works are scheduled to begin in Spring 2020 and should be completed by 2022. These defences will tie in with the previous work carried out at Anchorage Park and at Milton Common in 2016.

economically affordable and socially acceptable options need to be identified to manage Langstone’s flood and erosion risks into the future. The technical and economic appraisal of options is complete, and a set of initial preferred options have been identified.

Over the next few months the team will carry out an environmental appraisal of these options, undertake further modelling and engage with our key stakeholder working group, before presenting the final preferred solutions to the Langstone community later in the year.

Langstone FCERM Study

Timber maintenance works were carried out along the south Hayling Island coastline during March and April 2019. These works were undertaken by JT Mackley and Co Ltd, and lasted a little more than three weeks on site. 24 timber groynes were repaired, along with two sloping timber revetment structures. In addition, three navigation markers were reinstalled at the seaward end of the groynes and two more were re-secured. Following completion of the works the timber structures will continue to be regularly monitored to assess their condition and effectiveness, alongside the other coastal defence

South Hayling Island Timber Coastal Defence Maintenance

Over the past year, the research team here have been busy surveying the shingle beach at Hayling Island as part of a year-long Tracer Pebble study being carried out to inform and support the South Hayling Beach Management Plan.

Approximately 1,000 Tracer Pebbles were tagged with Radio Frequency Identification tags, which broadcast a unique number and accurate GPS location when scanned with specialist survey equipment. The tagged Pebbles were deployed at various sites along the frontage in April 2018 and since then, regular retrieval surveys have been carried out to help identify patterns of sediment movement along the frontage, including transport rates and direction.

Tracer Pebbles

The image above shows some initial results from five of our nine deployment sites, with each coloured dot corresponding to the position of a pebble over the different survey days.

Further detailed analysis is yet to be completed, but these early results are already proving valuable in helping us to understand better the behaviour and response of the shingle beach at various locations along the frontage.

For more information on how this method is used and for examples of other studies, please visit our website at www.escp.org.uk.

The project team have been working hard on the appraisal of the shortlisted options, since they were shared with the Langstone community late last year.

From this shortlist, the most environmentally sustainable, technically feasible,

structures. This will ensure any defects are identified early and repaired as part of the Havant Borough Council coast protection maintenance programme.

Maintenance at South Hayling

The surveys will take place between April and June 2019, with data collected by our staff using a variety of methods, including GPS attached to backpacks and quad bikes. This data once processed by our survey team, is used to investigate the effects of seasonal changes around the coast and to gain better understanding of the coastline and its processes.

Regional monitoring baseline & topographic surveys

Gosport FCERM schemes (Alverstoke, Seafield and Forton)We have developed outline designs for all 3 of these priority coastal defence schemes and are now in the process of appointing a consultant to help advance the schemes through the detailed design (Alverstoke & Forton) and enhanced outline design (Seafield) phases.

Once built, these schemes will reduce flood risk to 541 Gosport homes until 2070. The project team has secured funding for Alverstoke detailed design, consenting and construction along with Seafield enhanced outline design. Additionally, an outline business case has been submitted to unlock further funding from the Environment Agency for detailed design, consenting and construction funds for the Forton Scheme. The project team has worked with St Vincent’s College to develop a shared vision that will meet Gosport Borough Council’s flood and coastal erosion risk management scheme objectives as well as providing a solution that will benefit the local community and the college.

Our Surveyors are starting to undertake regional monitoring baseline and topographic surveys of the beaches in Fareham, including Hill Head and Chilling Cliffs.

The research team will use this data to update existing knowledge regarding coastal evolution and understand any localised changes over the past year. All data is freely available from the Channel Coastal Observatory website.

ESCP UpdatesThe ESCP survey team recently branded itself as the Geomatics Division to reflect the cutting edge geomatic and geospatial technologies our surveyors operate within. Using the very latest technology including RTS (robotic total station), GPS (global positioning systems), 3D laser scanners, ATV’s (all terrain vehicles) and our latest additions, two UAV’s (unmanned aerial vehicles). Our Geomatics Division are leaders in public service innovation using pioneering technology to capture details with accuracy. Our drone capabilities provide the ability to undertake higher

The Standing Conference on Problems Associated with the Coastline (SCOPAC) and The Southern Coastal Group (SCG) are coastal group networks based in central southern England. They bring together neighbouring Local Authorities and organisations that are involved, or interested in, the management of the coastline. Whilst they formed as separate groups, they now work as sister organisations to share and develop research, best practice and resources within the region.

Through SCOPAC and the SCG significant benefits have been achieved across the region for over 30 years. However, there are now a number of increasing pressures on coastal management which are threatening the wider sector. These include: climate change and sea level rise, public sector austerity and budget cuts, retirement of knowledgeable senior engineers, shifting policy and guidance.

risk and more complex surveys such as environmentally sensitive or difficult to access locations, high rise building inspections, detailed aerial photography or construction site inspections and surveys. Our team of skilled surveyors will soon be introducing these new tools to support ongoing projects and the regional monitoring programme. To support this new technology we are deploying a Trimble R9s receiver at our Havant Plaza office. This will collect GPS data and then broadcast live corrections out to our surveyors on the ground. Once testing is completed this new station will join the existing regional monitoring GPS stations providing improved resilience and redundancy when undertaking topographic surveys.

The ESCP has been pioneering a more open approach since its inception by truly working with others to facilitate place shaping and place making through the implementation of its projects, as well as ensuring place keeping through asset maintenance after they have been delivered. The ESCP have succeeded in implementing a more joined up approach to FCERM across the Local Authorities that it serves, particularly through working closely with the respective planning teams.

Alongside this the ESCP have continually lobbied for a more joined up approach between national and local government agencies highlighting, the need for them to recognise the benefits of aligning multiple objectives and multiple funding partners to deliver holistic outcomes for communities.

To showcase the work of the ESCP in this area, Mark Stratton will be presenting a paper at the Institution of Civil Engineers (ICE) Coastal Management Conference in September 2019.

The conference will gather delegates from around the world to focus on new approaches to coastal engineering that integrate planning and ‘place-shaping’ to encourage bold adaptation to coastal change, and that balance environmental and community concerns.

Mark will also be presenting at the Environment Agency Flood and Coast Conference in June 2019.

As part of a skills workshop session entitled ‘An industry fit for the future’, Mark will present the benefits and challenges of partnership working, and how as an organisation we have made ourselves fit for the future through team development.

The Ringed Plover (Charadrius hiaticula) is a small, wading bird. Ringed Plover breed on beaches around the UK coast.

There are currently 6-8 pairs of Ringed Plover that attempt to nest in this area, but they are rarely successful due to issues such as disturbance and trampling. The pilot fence will provide an area where the impact of these factors is reduced.

Ornithology News!Ringed Plover Nesting Ground - Pilot Study Eastern Solent Coastal Partnership are working in conjunction with Hampshire and Isle of Wight Wildlife Trust to test a fenced area to protect a known nesting site for Ringed Plover on Hayling Island. Installation of the fence was completed beginning of February 2019.

This fenced area is a pilot to encourage and protect nesting Ringed Plover as well as other nesting birds. The fence was fully installed at the beginning of February 2019.

Vegetated shingle is characterised by specialised plants that have adapted to survive in harsh coastal conditions. Shingle habitats are also particularly important for invertebrates and for some breeding and roosting birds.Hook Lake - Bird SurveysMeanwhile, members of our environment team have been undertaking ornithological surveys at Hook Lake, Warsash. These surveys seek to monitor bird movements 3 hours preceding high and low tides.

This data will provide an enhanced understanding of bird usage in the area and its importance for overwintering birds such as Brent geese. Both day and night surveys have been carried out here throughout the winter months, as well as at other locations including Gosport and Hayling Island.

The fence also provides an environment to

prevent trampling of vegetated shingle and aid in its establishment.
