Tidal Flood Risk Management | Lowestoft

Tidal flood risk management options

Tidal Floodwalls

Tidal Floodwalls will be built along Hamilton Road and Waveney Road to the North and around the Royal Norfolk and Suffolk Yacht Club and South Pier to the South.

There will be a mixture of solid floodwalls, demountable defences, floodgates and glass floodwalls. The glass floodwalls will run around the Yacht Club and the South Pier to maintain views of the marina and Port.

Construction of the floodwalls began in May 2021. To keep up to date with construction progress please visit the construction page here.

As part of the planning application for the tidal flood walls a Flood Risk Assessment was carried out to address how flood risk will change in the area as the project progresses:

Tidal Barrier

A tidal barrier will be built across the channel entrance to Lake Lothing on the seaward side of the Bascule Bridge.

The barrier had originally been designed to be a 28m mitre gate. Navigation Simulations for this option took place in April 2021 and showed significant challenges to the navigation of vessels entering the port. Following this a decision has been taken to extend the size of the mitre gate to 40m, which will maintain the current width of the navigation channel. 

As there is nowhere to divert the navigation channel, the barrier will be designed to keep disruption to a minimum by working over the winter months and closing the channel for only short periods of time. 

Transport Works Act Order

The tidal barrier requires a Transport Works Act Order (TWAO). This is granted by the Secretary of State and is needed when construction can change or affect navigation. A TWAO can take up to two years to be approved but we are working with our partners and stakeholders to make sure that we address concerns as early as possible.

To complete this work and to enable us to go ahead with the project we will of course need to work closely with local communities, businesses and organisations. Public consultations will be held at various points during the project. There will be opportunities for people to get involved or to be kept informed about how things are progressing.
