Ground investigation begins in Hirael to assist proposed new flood alleviation work

Date: 25/01/2021

Work is getting underway this week on ground investigation in the Hirael area of Bangor. The work, which will involve the use of a small drilling rig, is required to better understand ground conditions in the area, to assist Gwynedd Council with the design of a proposed new flood alleviation scheme.


The lower part of Hirael, close to Beach Road, has historically been vulnerable to coastal flooding. It is expected that this risk will increase in the years to come as a result of climate change and sea level rise. In order to reduce this flood risk, Gwynedd Council have received Welsh Government funding to design a coastal flood alleviation scheme for the area.


The project, which is currently at the planning stage, is likely to involve a new flood wall along the frontage at Hirael Bay. The ground investigation work will allow engineers to better understand the ground conditions so that the wall’s foundations can be designed.


Councillor Catrin Wager, Gwynedd Council Cabinet Member said: “We are well aware of the real risk that climate change poses to coastal communities like Hirael.


“As a Council, we have held various drop-in events over the years to discuss the Hirael Coastal Defence Project. The work that will be carried out over the coming weeks will play an important part in allowing our specialist officers to consider the best options for the proposed new flood alleviation scheme in Hirael.


“Every effort will be made to keep disruption to a minimum and we’d like to thank the public for their patience while this essential engineering work takes place.”


During the work, which will last until March, it is hoped that disturbance to the community will be kept to a minimum. There will, however, be some noise as a result of the drilling – this will be limited to daylight hours. Local footpath diversions are likely to be required for parts of the work near Beach Road carpark and the King George Playing fields. It is also likely that Glandwr Road, between Y Bae estate and Garth Road, may need to be shut to traffic for a short time.
