Coronavirus: council service information and advice

Information about changes to council services as a result of coronavirus

Portsmouth locals will have the chance to find out more at a pre-construction exhibition focusing on the next stage of coastal defences which will protect North Portsea Island from the risk of coastal flooding.

In the lead up to the start of construction, a public exhibition is being held at The Great Salterns Mansion Harvester, Eastern Road, Portsmouth on Wednesday 14th August between 1pm – 7pm. At the exhibition the scheme plans will be on display, as well as information on what to expect during construction and timescales for delivery. Project staff will also be on hand to answer any further questions.

This event follows on from previous public consultation held in March 2014, January 2015, April 2016, February 2017 and November 2018 which helped shaped the design of the scheme following public feedback.

The next phase of defences will be delivered in two parts, the first involving the construction of an earth embankment, a steel sheet pile wall and raising the road adjacent to Kendall's Wharf on Eastern Road. The second stage includes the construction of a seawall along 2.4km of the Eastern Road, encasing the existing seawall and raising the defence level by approximately 1.2m.

The principal design for Phase 4 is now complete and construction on the first package of work is due to start in September 2019 on the Kendall’s Wharf section, which has just been approved by the local planning authority, and is expected to be completed by April 2020. The planning application for the second package of work, taking place along Eastern Road is due to be submitted in August 2019. Subject to planning approval, work could begin on this section of the defences in April 2020 with a view to being completed in late 2022. The designs for the second package of work will also be on display at the exhibition.

Councillor Dave Ashmore, cabinet member for environment and climate change at Portsmouth City Council said:

This event is a great opportunity to engage again with the public in the area about the new defences which are needed to protect Portsmouth from a flood event. There has been plenty of consultation already on the design of these defences which will add to the great work which has taken place at Anchorage Park, Milton Common and currently at Tipner.

The North Portsea Island Scheme, which is being delivered by the Eastern Solent Coastal Partnership on behalf of Portsmouth City Council,  covers 8.4km of coastline from Tipner through to Milton. Most of the area is low-lying and many of the current coastal defences are approaching the end of their effective lives. The new coastal defences are designed to significantly reduce the risk of coastal flooding over the next 100 years, reducing the risk of flooding from the sea to over 4,200 homes, 500 businesses and critical infrastructure including Eastern Road. On completion, the scheme will offer protection against a 1 in 500 year coastal flood event and will tie in with the defences built at Anchorage Park to the North and Milton Common to the South.
