About the Rhos-On-Sea proposals

Summary (optional)
start content


The coastal defences include a new rock groyne structure and adding sand to the beach. The beach height will be increased by about 5 metres at the seawall with approximately 1 million tonnes of imported gold sand pumped on to the beach via offshore dredging. This is the same approach that we used for Colwyn Bay beach in Phase 1c.

The new rock groyne will use material from existing rock groyne structures and rock armour, which would otherwise be buried beneath the new beach. Reusing this material means we don’t have to import more rock material.

The finished groyne will be higher and wider and will have a new arm added to create a fish tail design, which will reduce the risk of sand backwashing into the harbour.

This will provide a beach which is accessible at all times of the tide.

To protect the promenade from damage from overtopping waves, on the land side of the seawall, a 2 metre wide reinforced concrete strip will provide a robust surface that can withstand the coastal environment.


As well as improving the coastal defences, we want to make improvements to the promenade to maximise the benefits of the scheme.

Widening the promenade will give all users more room, allowing for Active Travel, family fun and recreational activities.

The upgraded promenade will feature:

  • 4 metre wide shared space for cyclists and pedestrians to improve safety
  • Activity zone with benches, planters, trees, play equipment and bins
  • Event spaces with feature paving
  • Public art feature near Combermere Gardens
  • Health markers – showing distance travelled from Colwyn Bay pier


The proposals include a new efficient lighting scheme for the area, in keeping with previous phases of the Waterfront scheme.


New waterfront planting will include:

  • Low and raised planters with groundcover planting
  • Trees in raised planters along the activity zone

Street Furniture

New street furniture will suit different users, activities and group sizes, with:

  • Picnic furniture
  • Benches
  • Play furniture
  • Cycle stands


The proposals include new shelters to replace the existing ones. The upgraded shelters will provide a new, safe and accessible space to rest or escape the elements.

The shelters include new features such as solar power lighting and an accessible design.

Water Fountain

The historic water fountain, currently located south of Rhos Harbour, will be relocated to the new activity zone. If possible, we aim to provide a new water supply to the fountain.

Concession Kiosks

To allow wider space on the promenade for cyclists and pedestrians, the existing outdated kiosks on West Promenade will be removed. We are looking for funding to relocate and upgrade the kiosks – this construction will be under a separate scheme, but we have included the necessary space and utilities as part of this proposal.


The proposals include changes to traffic flows to:

  • give space to widen the promenade to increase safety for pedestrians and cyclists
  • improve road safety following an increase in road traffic accidents along the promenade road

The promenade road along the bottom of the Cayley Embankment will be reduced to one lane of traffic, heading towards Colwyn Bay only. Cayley Promenade road will remain two-way.

The plans include:

  • changes to the layout of the junctions at either end of Cayley Embankment
  • new speed reducing features on West Promenade
  • pedestrian crossing points on West Promenade and Cayley Promenade

These changes will improve access for everyone along West Promenade, creating a safe and accessible public space and active travel route.


The proposals include a change to the grassland management to improve the biodiversity value of Cayley Embankment and benefit butterflies, bees, birds and small mammals.

The plans, along with the supporting documents such as the Environmental Statement and the Design and Access Statement, can be viewed in hard copy at Colwyn Bay Library, see here for opening times: Colwyn Bay Library.
