Issue details

To seek funding approval to undertake works to replace the existing failing gabion retaining wall owned by Fareham Borough Council, that prevents erosion of the river bank adjacent to Wallington Shore Road and potential flooding to the village.

The failing structure in need of replacement forms part of an erosion barrier which protects FBC owned land from erosion by the River Wallington.

The erosion barrier is formed of a gabion basket retaining wall 41m long.  At its closest, Wallington Shore Road is within 4m of the erosion barrier.  The structure has already begun to fail in places.  The structure has previously been maintained by FBC, but has now reached the end of its serviceable life and is no longer maintainable.

There is a high risk that a complete failure of sections of the FBC owned wall could occur under high river flow conditions, putting FBC owned land and Wallington village at increased flood risk.

It is proposed to replace the failing sections with a new gabion retaining wall in 2017 with funds from the FBC Capital Programme.

The details set out in the report have been developed in collaboration with FBC Finance, Estates and Legal teams.
