Stokes Bay Seawall Replacement Project
The important work to replace a section of the Stokes Bay Seawall has been successfully completed this summer, allowing the Alverbank East Car Park and the adjacent promenade to reopen after being closed to the public for several years. The project was managed by Coastal Partners and constructed by contractor Suttle Projects.
BACKGROUND
The Stokes Bay seawall and promenade constructed during the 1970’s has experienced several failures over recent years despite Gosport Borough Council investing in routine maintenance.
In February 2022, the low-height seawall to the east was unable to withstand the effect of Storm Eunice. As a result, substantial damage to a 135m section of the seawall was caused, putting Stokes Bay Road at risk of coastal erosion.
Funding
Financial contributions were initially secured from Gosport Borough Council and Hampshire County Council to deliver the project. However, due to further damage to the existing seawall increasing the project scope and inflation impact on construction costs, the initial funding allocation was insufficient to progress the project into construction.
To address the funding shortfall, the project team reviewed all possible opportunities, including Local Levy funding. In October 2023, the Southern Regional Flood and Coast Committee (RFCC) confirmed that a combined Gosport Borough Council and Hampshire County Council Local Levy bid to secure the remaining funding required for construction was successful.
PROJECT UPDATE - September 2024
The 135-meter sheet pile wall, along with the capping beam and promenade, is complete after four months of construction. Additional upgrades included improved drainage in the car park and the installation of a new handrail. The successful completion of this work ensures that this section of the wall is protected ahead of the winter storms, removing the need for ongoing and unsustainable maintenance. The project has been delivered on schedule and within the allocated budget.
LONGER-TERM VISION FOR STOKES BAY
Given the high costs associated with ongoing maintenance and the limited extent of the replacement works, it is clear that a longer-term strategic solution is required at Stokes Bay. Coastal Partners are in the process of finalising a Stokes Bay Option Appraisal and Outline Design Study which considers the future sea defences for the whole of Stokes Bay from the perspective of flood and erosion, transport, tourism, heritage and the environment. The study is being funded by Local Levy, Gosport Borough Council and Hampshire County Council.
