The next phase of plans to protect North Portsea Island from the risk of coastal flooding are underway following approval of the planning application for the first package of work in the Kendall's Wharf area of North Portsea Island.

The principal design for Phase 4 of the North Portsea Island Coastal Defence Scheme is now complete and will be delivered in two packages of work. The first, 4a, will begin in September 2019 now that planning approval has been granted and includes the construction of an earth embankment, a steel sheet pile wall and raising the road adjacent to Kendall's Wharf on Eastern Road. This work is expected to be completed by April 2020.

The planning application for the second work package, 4b, along Eastern Road is due to be submitted in August 2019. The work 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. Subject to planning approval, work should begin on these defences in April 2020 with a view to being completed in late 2022.

Councillor Dave Ashmore, cabinet member for environment and climate change at Portsmouth City Council said "the next phase of the North Portsea Island coastal defences is an important one as Eastern Road is a key path in and out of the city and these plans will protect this section of coastline from the real risk of flooding. We've already seen the great work around Tipner Lake as part of the scheme and I'm excited to see the next stage of work around Kendall's Wharf begin.

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.
