About the Central Prestatyn Coastal Defence Scheme
On Monday 8th July 2024, work will commence on the new Beach Access Ramp, which is located at the end of the Central Footpath running through the golf course, opposite Lyons Robin Hood Holiday Park.
There will be a temporary footpath diversion in place to maintain promenade access at all times.
A new temporary golf course crossing gate will be installed to replace the existing golf course crossing gate.
Access to the beach will be maintained at all times.
This work will take approximately 10 weeks.

The town of Prestatyn in Denbighshire is protected from coastal flooding by defences along the waterfront.
Due to the age and condition of these defences they no longer provide an adequate level of protection. Within the next 50 years, rising sea levels and bigger storms caused by climate change will result in waves overwhelming the defences more often.
Without improvements to the sea defences, the risk of coastal flooding faced by homes and businesses in Prestatyn is likely to increase in future.

The age and condition of some of sea defences that protect Prestatyn from coastal flooding mean it's possible that the defences will be eroded and undermined, and eventually fail. In addition to this, rising sea levels and bigger storms caused by climate change will result in waves overwhelming the defences more often.
Without improvements to the sea defences, the risk of coastal flooding faced by homes and businesses in Prestatyn is likely to increase in future.
Central Prestatyn Coastal Defence Scheme: Location plan
- The existing coastal defences in this section are about 70 years old and in particularly poor condition. Coastal defences generally have a design life of 100 years so are very likely to be breached unless significant works are undertaken in the next 30 years.
- If the existing defences fail in this location, the flood risk to over 2,000 properties in the Prestatyn area will increase significantly. This is because low land elevations in the area behind the defences will allow any flood water to spread and flood a wide area.
A wide range of options were considered for reducing the flood risk. These fell into two categories:
Source options
- Philosophy: Prevent flood water from exceeding the front line of defence. Hold the sea back.
- Examples: Beach recharge, breakwaters, sea walls.
Impact options
- Philosophy: Reduce the impact of overtopped water by preventing it reaching people, property and infrastructure. Control the flood water if it comes over the defences.
- Examples: Set back walls, embankments, property flood resilience.
An appraisal was carried out to work out the best options. The best solutions for each category were as follows:
Source option
- Solution: A new sea wall and rock armour revetment (similar to the East Rhyl Coastal Defence scheme).
- Indicative cost: £50 million
Impact option
- Solution: Earth embankment that is set back from the front-line defences, following the boundary of the golf course (Flood water coming over the defences during a storm would be contained within the golf course until it can discharge back to sea)
- Indicative cost: £25 million
As well as the cost of the two options, the appraisal also considered social and environmental impacts, including recreation and tourism, local businesses, biodiversity, visual impact, heritage, carbon footprint.
The 'Source Option' provides recreation and tourism benefits, but comes at a much higher cost and has a greater negative impact on the environment including higher carbon emissions associated with its construction and full promenade closure with restricted beach access in the immediate location for the duration. This option cannot be justified.
The 'Impact Option' of a set back earth embankment is the better option.
Building a set-back embankment is a cost-effective way of protecting homes and businesses from flooding while minimising the impact on the environment.

December 2022
Funding has been granted.
November 2022
On 11th November 2022, a second public meeting was held at Rhyl Golf Club. This was to recap residents of the schemes proposed plans and an opportunity for the residents to ask any questions.
July 2022
Planning was approved for the scheme in July 2022.
The planning application was submitted to Denbighshire County Council and is available to view online. The application reference is 45/2021/1248.
December 2021
A question and answer event took place on 13 December at Rhyl Golf Club for residents and stakeholders regarding the scheme ahead of the planning application submission.
The planning application was submitted to Denbighshire County Council on 16 December, having been adapted (where possible) based on responses from the Pre-Application Consultation period.
October and November 2021
The scheme entered its 28-day pre-application consultation period in accordance with Schedule 1B - Article 2C and Schedule 1C - Article 2D of The Town and Country Planning (Development Management Procedure) (Wales) Order 2012 (as amended).
This enabled the public to view and comment on the planning application before it was submitted for the scheme. These comments have been considered in the final design for formal submission of the planning application.
July 2021
Balfour Beatty have developed the proposed methodology for constructing the scheme.
January 2021 - July 2021
JBA Consulting have been developing the detailed design for the scheme to allow details such as the exact location, height and width of the proposed set-back embankment to be finalised.
Further environmental assessments and surveys have also been carried out.
December 2020
- Denbighshire County Council planning department are consulted regarding the environmental assessments that will be required for a future planning application
- Environmental, archaeological and geotechnical investigations are undertaken on Rhyl Golf Club
August 2020
JBA Consulting were appointed to complete the detailed design for the scheme and assess the social and environmental impact.
January 2020
The Welsh Government approved the Outline Business Case. Following this, Denbighshire County Council apply for and are granted more funding to enable the preferred option to be further developed.
May 2019
An Outline Business Case for the scheme was completed which assessed the risk of flooding and erosion and presented the preferred option.
July 2018
Balfour Beatty was appointed by Denbighshire County Council to develop a business case for the scheme, to allow access to funding from the Welsh Government's Coastal Risk Management Programme.
Construction will start early 2023 and will take approximately 3 to 3 and a half years.
Should you have comments relating to the planning application, these should be directed to Denbighshire County Council's Planning Department.
Construction Stages
There is soft ground beneath the site, which means the construction needs to take place in stages, which will involve stand-down periods of approximately 9 months between the construction stages. The settlement of the ground will be monitored throughout the stand-down periods. Depending on the results, this may lead to a change in the number of construction stages or the length of the stand-down periods. Overall project duration is expected to take approximately three to three and a half years.
Stage 1: February 2023 to September 2023 (Rhyl Golf Course closed)
- Mobilisation
- Natural Resource Wales culvert protection
- Embankment Works
- Beach Works
Stage 2: October 2023 to September 2024 (Rhyl Golf Course open)
- Embankment Works
- Footpath construction
Stage 3: mid-September / early October 2024 to autumn 2025 (Rhyl Golf Course open)
- Embankment Works
- Topsoil and seeding
- Construction of flood gates
The Golf Course clubhouse will remain closed for the duration of the scheme. The parcel of land to the end of Garford Road will be utilised by the Golf Course throughout the duration of the scheme for access to the Golf Course. The management of the existing floodgate will continue with ongoing liaison between Balfour Beatty, Denbighshire County Council and Rhyl Golf Course throughout.
Where possible, existing footpaths will be maintained during the stand-down period.
Balfour Beatty’s normal working hours on the promenade will be Monday to Friday between 08:00 and 18:00. Saturdays would only be by prior agreement with the Council. Works on the beach would follow irregular working hours to suit the daily tide times.
The main compound will be situated within the existing Golf Course car park. A number of temporary site access points will be installed on Rhyl Coast road and from within the Golf Course car park.
Two construction routes will be in use to supply the required materials during the scheme’s development. These are:
- From the A55 following the A525, entering the scheme area from the west
- Via the A548 from the east
Promenade closures
Update: unfortunately, due to poor weather conditions, the promenade closure is going to extend into a third week. We expect the work to be completed by Friday 11 October (weather dependant).
Stage 3: As of 23 September 2024, the promenade will be closed for a period of 2 weeks while we re-surface and improve the existing promenade. This will be from Garford Road car park up to the most eastern point of the scheme, where the flood gate is situated before Ffrith Beach.
Pedestrians will be redirected along Rhyl Coast Road and through the Golf Club’s Central Path. Access to the promenade will be available through Green Lanes and Terfyn Pella path. Beach access at Garford road via the temporary golf club car park will still be available. Promenade marshals will be in place at the crossing points to ensure pedestrians can cross safely.
