July 2020 Update
Work is progressing on the Portsmouth City Council North Portsea Island Phase 4 scheme. Before our contractor Mackley starts work on the defences next to the coastal path, a section of the coastal path will be temporarily closed from 1st July 2020, as shown in the map below. This is to keep the public safe. Diversion signs will be in place until the new, wider footpath consistent with the rest of the scheme opens to the public; the footpath along Eastern Road will remain open throughout works.
There are no road closures planned for the Eastern Road.

The next stage of the North Portsea Island Coastal Defence scheme is underway.
Work begins on the first stage, Kendall's Wharf, on 25th November 2019 and will continue until Spring 2020. The works include the construction of an earth embankment and wall, as well as raising the access road into Kendall's Wharf.
The site compound due to be installed from the 25th November 2019 will be located adjacent to Aggregate Industries and the construction work will be carried out by Mackley (www.mackley.co.uk)
Two temporary access roads will be built before work starts on the embankment and wall. There will be a diversion in place for the coastal path to keep the public safe. Access to the sailing club and watersports centre will be maintained using one of the temporary roads and businesses will be open as usual. There are no road closures planned for the Eastern Road.
A planning application for the second stage of the work at Eastern Road was submitted in September 2019. Subject to planning approval, the work is planned to begin in April 2020. This work will include the construction of a seawall and raising the footpath in order to maintain views.
Public space and paths along the coast will be improved and any areas cleared of vegetation will be replanted with a range of specially chosen species including a mixture of grasses, trees, shrub and species rich meadow. The new plants will be more visually and ecologically diverse than what was there previously, creating a better habitat for local wildlife.
The work at Kendall’s Wharf and Eastern Road will tie in with the defences already built at Anchorage Park to the North and Milton Common to the South. The previous phase at Tipner Lake is now complete and reopened to the public in September.
The next set of defences, the fourth of five phases which make up the £58m North Portsea Island Coastal Defence Scheme, has been split into two sections: Kendall’s Wharf and Eastern Road.
Kendall’s Wharf, the first section, has full planning permission and is due to start in November 2019. This section covers an area of approximately 300 metres starting at the northern part of Eastern Road near Kendall's Wharf. This will involve raising the road and constructing an earth embankment.

The second section, Eastern Road, involves the construction of a sea wall along 2.1km of coastline at Eastern Road. A planning application has been submitted for this work and is currently being consulted on through the Local Planning Authority via the Portsmouth City Council website. Subject to planning approval, work should begin on these defences in September 2020. (To view the planning application that was submitted on 5th September 2019, please click here.)
A public exhibition was held on the 14th of August 2019 at the Great Salterns Mansion Harvester on Eastern Road. The aim of the event was to re-engage with the community in the lead up to construction, in particular the Harbourside Park residents and businesses along the frontage, and to display the designs and what will happen during construction. It was also an opportunity to get feedback from the public:
- In total, 82 people attended the exhibition event.
- 73% completely or partially support the new coastal defences at Kendall’s Wharf.
- 65% completely or partially support the new coastal defences at Eastern Road.
Phase 4 of the North Portsea Island Coastal Flood Defence Scheme
New coastal defences are being built as part of the North Portsea Island Coastal Flood Defence Scheme, which have been designed to reduce the risk of coastal flooding and erosion to the area over the next century. The ESCP have successfully gained approval and Flood Defence Grant in Aid funding for £58.5million to implement these works, which when constructed, will provide one of the highest standards of coastal flooding protection in the country. The project has been split into five phases of works, three of which are complete, and the fourth phase is under construction.Example of construction vehicles and methods at NPI Phase 1, 2 and 3
- Phase 1 - Anchorage Park 2015 - 2016: the construction of 1.4km of earth embankment with rock revetment toe completed in 2016 at a cost of c.£5m;
- Phase 2 - Milton Common 2016: the construction of 1.5km of a set back earth embankments and rock revetment structure, completed in 2016 at £3m;)
- Phase 3 - Tipner Lake 2017 - 2019: iis the construction of 1.9km of a seawall which commenced April 2017 and is programmed for completion by the end of Autumn 2019;
- Phase 4a&b – (a)Eastern Road and (b)Kendall’s Wharf 2019 - 2022: is the construction of a seawall with road raising at the entrance to Kendall’s Wharf;
- Phase 5 – Ports Creek 2023 - 2024: Currently going through a detailed design review which once complete will lead to the procurement of the contractor.
JT Mackley and Co. Ltd has been chosen to deliver the fourth phase of coastal defences which will protect more than 4000 homes and almost 500 businesses in North Portsea from the risk of coastal flooding. Mackley was selected from a shortlist of four expert contractors, all of whom carry extensive industry experience and produced very competitive bids.
Mackley has worked with Portsmouth City Council prior to this bid, delivering the first phase of coastal defences at Anchorage Park in 2015 which added protection to the area and vastly improved public areas with effective landscaping.
