Other Information

Grid Ref: SH60283 17218 East: 260283 North: 31727 Background Barmouth is a town on the west coast of Snowdonia in Gwynedd. The North Promenade is the northern section of the Barmouth beach frontage, extending from the residential housing estate at Heol y Llan to the northern extent of the promenade wall. This section of the frontage supports the amenity value of the full promenade, whilst providing coastal protection to the adjacent land, properties and infrastructure. The 1.2km study area comprises a mix of hard coastal defences (sheet piled wall, concrete revetment and wave recurve wall, with masonry setback walls). Barmouth, and in particular, its north promenade is at risk of coastal flooding and erosion. It is commonplace to see overtopping at the north-most end of the promenade. Some 757 properties have greater than a 1 in 100 chance of coastal and/or surface water flooding in any year. The Barmouth North Prom Flood Alleviation Scheme (FAS) was included as part of Welsh Government’s Coastal Risk Management Programme and now forms part of Welsh Government’s Capital Programme. The outline business case (OBC) was approved by Welsh Government in 2021 – with a preferred option identified. Funding was granted for the detailed design stage (Full Business Case) in June 2023. The funding for Construction work will be subject to FBC approval through Welsh Government and Gwynedd Council. Preferred Option The preferred option involves work to address defects, extend the service and improve the existing defences, including; - Extend the life of the existing sheet piles with refurbishment works. - Raise the primary defences and add protection to the structure toe by a rock-toe or shingle beach profile (where material stability allows). - Strengthen and raise the set-back flood wall. - Improve demountable barriers and drainage. - Public-realm improvements including provision of dwell areas, beach access and connectivity to the wider community.
