Essential Website Maintenance – Thursday 9th January 2020

We will be carrying out essential website maintenance in the afternoon which will affect some functionality. We apologise in advance for any inconvenience the work may cause and will do all we can to keep disruption to an absolute minimum.

Overall Scheme


Summary (optional)
Old Colwyn coastal defence
start content

The entire scheme runs 1.2km from Porth Eirias in the west to Splash Point (by Old Colwyn Arches) in the east and we estimate it will cost approximately £35M in total. Because we haven’t yet secured a source for all this funding, we are completing the scheme in phases.

Why the work is important

During storms, the promenade at Old Colwyn regularly suffers from water coming over the top of the seawall, damaging the promenade and railway embankment. Sections of the promenade have to be closed to the public a number of times every year. The sea wall frequently suffers damage and needs regular repairs.

The condition of the sea wall has deteriorated over the decades, and the beach levels along this section of frontage have gradually dropped. There is now a heightened risk of these vital coastal defences collapsing during large storms.

Improving this protection is even more important because the promenade protects critical infrastructure, including the A55 Expressway and the main London-Holyhead railway line.

Community benefits

We want to provide as many additional benefits as possible while we complete these vital coast protection works, to complement what has already been done elsewhere in the bay.

Plans

The overall scheme includes:

  • Protecting the Victorian sea wall with a rock barricade
  • Raising the height of the promenade
  • A new fishing platform
  • Accessible beach access
  • Seating and outdoor classroom areas
  • Lighting
  • Electric vehicle charging points

These plans show our proposals for all the improvements we would like to make at Old Colwyn promenade. These improvements are not yet all programmed, and depend on further design and funding availability.
