Public consultation

The public consultation has now closed as of the 9th of May, 2021. Thank you to all of those that participated – We will be considering each and every comment as the project moves to the next phase, which is the detailed design phase. If you have any general enquiries about the project, you are welcome and encouraged to contact the team via the ‘Contact Us’ page.



3D Model of the proposal

1) Scheme frontage

Our proposal is for a new sea wall, replacing the existing wall which is currently in a poor condition. To provide adequate flood protection, the wall would be raised some 1.3 m (4’3”) above the existing level of the promenade.

We are currently favouring a modular blockwork wall similar to the one in Rhyl harbour which is shown here. To find out how this wall will impact the amount of seawater entering Hirael in a storm event, click on the button below.

The height of the wall will have some impact on the view from the carpark and promenade. Options for mitigating this impact could include raising the land behind as shown in the second image opposite.

2) Flood gates

Access to the seafront is important, and therefore two sets of flood gates will be installed to maintain this accessability: one on Glandwr Road, and the other next to the Welsh Water pumping station.

These gates will only be closed during periods of high water. Similar flood gates have recently been installed at Y Felinheli (photogrpahed) as part of a new Gwynedd Council-led flood alleviation scheme.

3) Earth embankment

A short section of flood bank will be built near Welsh Water’s pumping station. This embankment will look very similar to that constructed in Beaumaris. The photo opposite is reflective of the approximate height and appearance of the embankment.

4) History

The Hirael frontage was once a prisoner of war camp for Italian soldiers in World War 2. A fig tree planted at the time still grows near the existing sea wall. There may be oppertunities to provide information on the history of Hirael as part of the scheme. If you would like to learn more about the tree, or even have a cutting of your own, click the link below…

5) Enhancements

There may be oppertunities for improving the overall appearance of the promenade in Hirael through the introduction of new seating areas, plants, flowers and recreational spaces.

This photo is of a flood alleviation scheme recently completed in Littlehampton, West Sussex with similar aspirations.
