Beach Nourishment Scheme

Beach Nourishment Scheme

A nine week programme of works is being carried out, to replenish beach material adjacent to the new stepped sea
defences in the main central stretch of Cleveleys.

This work requires a compound to be built and beach access to be gained from the northern most end of Rossall Promenade, similar to works which have been carried out in the past.

When the new sea defences were constructed at Cleveleys, it was expected that north shore drift would deposit sufficient material at the base of the steps to protect the foundations and their base from erosion. This has happened in one or two spots – inside the curved areas – but not elsewhere.

If you have been along the promenade recently you will see that the steel sheet
piles are exposed at the foot of the steps where they meet the beach. This is
not how the sea defences are designed to work.

Extending the rock groynes

The groyne adjacent to the cafe is being extended in rock by a significant 41m, and the three groynes south of that (heading to central Cleveleys) by 10m each (also with rock) to reduce the northwards erosion effect of subsequent tides. Shingle is then being imported to reinstate the design and make the sea defences work as they should.

The beach level will be raised against the steps and then tapered out in a seawards direction to meet the existing beach level, creating a more natural slope such as is seen on the shingle beach of North and Rossall Promenade. This will in turn reduce the depth of the water and reduce the depth of the waves which will make the promenade more safe to pass at high tides by dissipating the energy of the waves and how far they can travel onto the concrete pathway. An added bonus will be that at high tide there is a possibility of a dry area of beach that can be used against the steps.

Site compound

A compound will be built adjacent to the Five Bar Gate on Rossall Promenade which will be the base for works throughout the project. This will require a temporary reduction in parking spaces for the duration of the works and pedestrian access in that section will be via the rear pavement and not the promenade walkway. While heavy machinery is being used on the beach, banksmen will be in attendance to ensure that safety of beach users is maintained at all times.

The first phase of works will be to extend the groynes, the rock for which is being imported from Carnforth by road. The sand and shingle will then be brought in. A significant amount is being transported from Fleetwood where it is currently being stored at the back of the boating lake. It will be moved by lorry from there to Cleveleys, along the main roads and Thornton Gate. When all the shingle has been used from Fleetwood, additional material will be imported from elsewhere and also brought in by road. It will be tipped at the compound at Rossall Promenade and moved to its final position on the beach by tipper truck.

Inevitably, this work will cause some disruption to nearby residents and to try and reduce this, the speed limit of the trucks on North/Rossall Promenade from Thornton Gate will be restricted to walking speed (5-10mph). Works will be carried out during daylight hours between Monday and Friday and of course at low tide. However, there will be an average of 10 wagons a day bringing in stone, and frequent lorries during low tide working times when the shingle is being delivered. (Because of the tides, work times will be intense followed by quiet periods when the tide comes in and work has to slow down).

These works have to be carried out to ensure the longevity and effectiveness of the sea defences at Cleveleys, so the emphasis will be on completing them as quickly as is possible.

Contact details:

The project will be documented through this website with weekly updates about what is happening on the ground. If you have any issues or questions do not hesitate to get in touch by ringing 07932 143431 (or send a text) and we will do our very best to help. You can also email jane@theRabbitPatch.co.uk . We will
keep you informed when key parts of the construction are carried out.

As a matter of courtesy the project team have written to residents in the affected areas to let them know that that this work is being carried out and to provide contact details. The project team will endeavour to complete the work with as little noise and disruption and as quickly as possible. Wyre Council and Birse Coastal would like to apologise in advance for any inconvenience caused by these essential works which will make a significant contribution towards protecting Cleveleys from coastal flooding for the future.

…………………………………………………………………………………………………………………………

You might remember that the beach along the seafront at Cleveleys was shingle, before the new sea defences were built.

At the time of construction, the shingle material was pushed seawards in the expectation that it would return once works had finished. However, most of the shingle has moved northwards to the areas of Fleetwood generally around Rossall Point.

The consequence of this is that the beach at Cleveleys is lower than it was planned for – which means that the base of the foundations are exposed in places at the bottom of the steps. ‘Sheet piles’ were rammed vertically, deep into the beach before construction, and the concrete steps sit up against them to prevent movement and form a solid base. It’s the very top edge of the metal sheet piles that you can now see, exposed by the sand which was intended to cover them.

To solve this problem, the beach is going to be built back up again. Firstly, the groynes on that stretch will be extended to prevent north shore drift picking everything back up and washing it back to Fleetwood. As when the terminal groyne was built near the cafe, a short foundation will be dug in the sand on the beach and lined with a geotextile fabric, and boulders sat on the top, to extend the groynes.

When that has been done, shingle will be extracted from the beach at Fleetwood where it is currently being stored in the boating lake area and transported to Cleveleys to reinstate the beach to how was before the sea defence works started.

This will solve two problems in one, because the shingle at Fleetwood has created a channel on the beach that the incoming tide fills, but it’s not draining properly and leaving behind a muddy residue with rubbish deposits, which are unsightly. So in preserving the beach at Cleveleys, it will also clean up a problem at Fleetwood.

To do any kind of work like this a license has to be obtained from the Marine Management Organisation (MMO).
