Portchester to Paulsgrove

Portchester to Paulsgrove Coastal Flood and Erosion Risk Management Scheme Update

Project Information

There are currently 361 residential and 108 commercial properties at risk from coastal flooding in Portchester and Paulsgrove. This is expected to increase with the effects of climate change to 662 residential and 141 commercial properties at risk by the year 2115.

Plans to improve coastal flood defences covering the area of coastline between Portchester Sailing Club and Port Solent are currently under development.

The project is being run by the Eastern Solent Coastal Partnership on behalf of Fareham Borough Council and Portsmouth City Council.

The design of the new defences will aim to reduce the risk of coastal flooding and erosion.

Project Update

The scheme is currently in the outline design phase. A business case for funding to undertake the detailed design and construction of the scheme was submitted to the Environment Agency in August 2017.

The team have now received approval from the Environment Agency for funding towards this scheme, however this is subject to a further significant external contribution to the scheme.

If the contribution can be secured, it will enable the scheme to move into the pre-construction phase. The pre-construction phase will see further public consultation events take place, the development of the scheme’s detailed design, and securing of the necessary licenses and consents for the construction works to take place.

The scheme is likely to be constructed over a two-year period, with the earliest start date on-site being April 2020, depending on funding. Defences will be put in place to reduce the risk of coastal flooding, designed to a 1 in 200 year standard of protection for the next 15 years. Future phases of the scheme will also be necessary, as the current defences  will be replaced as they reach the end of their useful life. 

A summary of the proposed works for the Portchester to Paulsgrove frontage can be seen below:

The outline design options for the first phase of works, which will be further developed throughout the detailed design stage, are also shown below:
