Tree and shrub felling

As part of the preparatory ground works for the construction phase, it is with regret that a small number of small trees and shrubs will need to be removed to make way for the scheme. This is advance work in order to minimise the risk of distrubing nesting birds later on. Two small pine trees including a Leylandii will be felled. As part of the project, the trees will be replaced with native species, and we remain comitted to planting two trees for every tree felled.

Results of the second public consultation

Follwoing our second round of public consultation in October 2022, we’ve composed a document outlining our findings. The comments and feedback we recieved were passed on to the detailed designers. Have a look at the report below:

The scheme goes to tender

The detailed design phase of the project is wrapping up, and now we are inviting building contractors to bid for the build-phase. Potential contractors have until the 24th of February to prepare their bids for review. Take a look below:

Public drop-in session

Following the drop in session, several members of the public wished to fill out our questionnaire online. The button to fill it out is below.

The questionnaire’s results will be collected on the 24th of October, and will be shared with our detailed designers.

Public drop-in session

On the 5th of October, representatives from YGC undertook a public drop-in session at the Crosville club which was attended by approximately 40 members of the public. This was a great oppotunity for us to gague the public’s feelings towards the project, what they feel should be delivered, and things which they have concerns over.

Overall, there was a very positive attitude towards the development of the scheme, with many looking forward to seeing the Hirael promenade being tidied up and improved.

There were several notable concerns raised, which we have taken onboard and will take back to the detailed designers. Principally, there were concers over being able to see over the new wall, leading to the conclusion that the need for a split-level promenade is essential. Other concerns included the impact of lighting on wildlife, and the need to include as much cultural and historical information as is practical as part of the scheme.

Public drop-in session

On the 5th of October, representatives from YGC will be setting up a short drop-in session in the Crosville social club in Hirael between 15:00 and 18:00. All are welcome to drop by and ask questions about the scheme, and to have a look at the latest plans for the area.

We will also be sharing what additional aspects we’re hoping to deliver as part of the scheme such as improved cycling infrastructure, more seating, and visual enhancements.

We welcome any comments you may have, and will take your comments back to the detailed designers.

On-site public engagement meeting

On the 15th of July, representatives from YGC will be setting up a short drop-in session on the frontage in Hirael between 12:00 and 13:00. All are welcome to drop by and ask questions about the scheme, and to have a look at the latest plans for the area.

Planning application approval

The first half of 2022 has been a busy one for the scheme. The detailed design of the scheme is well underway, and lots of work is being done surrounding the additional benefits the scheme could bring following public feedback. In the meantime, the scheme has been granted full planning permission, and our marine license has also been approved which are important milestones for any civil engineering scheme.

Storm Eunice update

Storm Eunice brought widespread coastal and inland flooding, and wind damage to large parts of the U.K. on the 18th of February, and NRW issued a flood alert for the Hirael area due to anticipated high tide. Thankfully, the storm passed Hirael without indicent due to the storm’s wind direction, and the high tide not coinciding with the highest wind speeds. Despite this, sandbags have been placed across the slipway in front of the Nelson pub as a precaution, with more stormy weather forecasted for the week ahead. 

December 9th 2021

Planning and marine license applications submitted

Following a period of hard work from the team, all the relavent documents pertaining to the planning and marine license aspects of the scheme have been pulled together and submitted to Gwynedd Council. For details and to view the documents, click the button below.

Green transport feasibility study

A feasability study is currently underway to invesigate the improvement of pedestrian and bicycle links between Hirael’s promenade and Lon Las Ogwen in Porth Penrhyn. A decision on whether to proceed with this aspect of the wider scheme will be made depending on the outcomes of this study. This is not exclusively part of the flood alleviation scheme project, but it is hoped that they can be intergrated.

Conclusion of ground investigations

The second phase of ground investigations at the site are now complete. As part of these investigations, the previously sheer drop to the water adjacent to the entrance to Beach Road East car park has been replaced with aggregate. It has been tipped and shaped at the location of the slipway to allow temporary access onto the beach for the excavator. It has been left in place to improve the beach access temporarily. 

November 1st 2021

Further ground investigations

As part of the design work for the flood defences, further ground investigation works are currently being undertaken close to the King George Playing Fields in Hirael. The work will involve drilling additional boreholes as well as excavating trial-pits on the foreshore. The information collected will be used in the design of the foundations of the flood defences. Hopefully the work will have a minimal affect on local residents, but please contact us if you have any queries or questions.

Selection of a detailed design contractor

Following the tender process, we are delighted to announce that AECOM will be undertaking the deailed design of the scheme. Further details will follow as this element of the scheme gets underway.

Concept drawing in response to the public consultation

Following the extensive comments we recieved from the pulbic consultation, YGC have produced a concept drawing outlining how some of the suggestions put forward could be intergrated into the scheme. The plan includes the creation of information boards, benches, community art installations, disabled access to the field, spaces for plants and flowers, areas for catering services and outdoor exercise areas.


Please note that this plan is subject to change as the scheme moves forward. 

29th January 2021

Ground investiagtions get underway

The first few boreholes have been drilled along the promenade at Hirael this week. Some minor changes to the location of the boreholes have been made in order to maintain safe public access to the promenade. 


Please contact us if you have any concerns or queries. 

20th January 2021

Ground investiagtions to begin

Our drilling contractors will begin ground investigations from the 25th of January to the 31st of March. These essenstial works are being carried out to establish the the ground conditions on which the new defences will be built, and will assist engineers in designing the wall’s foundations.

This will bring some (mostly sound) disruption to the community for short periods during the work, and will involve temporary closures of seafront footpaths. For a short time, there will be no through access to ‘Y Bae’ via Glandwr Road.


Please contact us if you have any concerns or queries.
