Groundwork investigations begin for Boston Barrier today


Important groundwork investigations start today on the site of the proposed £90 million Boston Barrier.

he investigations will be focussed in the Port of Boston, the riverbed of The Haven and the embankment on the opposite side of the channel.

In the Port of Boston, a team will take concrete cores and dig trial pits. The information gathered will be used during the design of flood defence walls which will run along the quayside.

Boreholes will also be dug along the embankment opposite the port to gather information for the design of flood walls.

The public footpath which runs along the Haven bank will be closed during the drilling works and notices will be put in place.

Ground investigation works will also take place within The Haven river channel. These will be used to identify the make-up of the river bed. Samples will be taken using a floating pontoon located on the south side of the river. Vessels will still be able to pass.

The work is being carried out on behalf of the Boston Barrier Partnership by a specialist team of contractors from WYG and is expected to last 10-12 weeks.

Mark Robinson, Environment Agency Senior Coastal Advisor, said: “This is an important step forward for the Boston Barrier project as this will inform a significant amount of the design work that we are doing now. We are doing everything we can to reduce the risk of tidal flooding in Boston as quickly as possible.

“We will try and keep any disruption to a minimum but there is likely to be some noise while we drill the boreholes.”

Drilling will only happen in daylight hours, 8am-6pm, Monday to Friday. If anyone has any concerns, they can contact the Boston Barrier team at or by telephone on 01623 684550.

The site for the £90.2million multi-functional flood barrier is just downstream of Black Sluice Lock on the Boston Haven.

A spokesman for the Environment Agency added: “As well as reducing the risk of tidal flooding, during the boating season (April – October) the barrier will also manage water levels through Boston to create a safe and reliable inland navigation link between Grand Sluice and Black Sluice Locks.

“Water level management will be flexible so it doesn’t prevent future navigation to The Wash.”

The flood defence scheme is currently expected to begin construction in 2017 and be completed by December 2019.
