- A series of 18 rock groynes.
- A rock revetment and walkway/maintenance access from the promenade around Cobbold's Point to Jacob's Ladder.
- Recharge of the beach with imported sand and shingle between the Spa Gardens and Cobbold's Point.
- Provision of a ramp onto the beach for maintenance purposes.
- A series of steps from the promenade onto the beach.
- Replacement of the Bath Tap ramp.
The scheme safeguards nearly 1,500 homes from the affects of coastal erosion, as well as local businesses, tourist beaches, recreational gardens and key facilities. The overall cost of the scheme was ள million which was funded by a grant from the Environment Agency.
The scheme was constructed in two phases from August 2011 to February 2012 and from April to September 2012.
Phase 1 of the scheme comprised of the construction of the 18 rock groynes between the War Memorial and Cobbold's point, the recharge of the beach between the Spa Gardens and Cobbold's Point, the construction of the maintenance and Bath Tap ramps and the provision of the beach steps.
Phase 2 comprised of the rock revetment and walkway/maintenance access around Cobbold's Point.
A Shoreline Management Plan (SMP) is a strategy for managing flood and erosion risk for a particular stretch of coastline, over short, medium and long-term time periods. SMPs identify the best ways to manage coastal flood and erosion risk to people and the developed, historic and natural environment. They also identify opportunities where shoreline management can work with others to make improvements.
About 10 years ago the first round of SMPs was completed for the entire length of the coastline of England and Wales. Since then considerable work has been undertaken both in managing defences around the coast and in building a better understanding of the issues and behaviour of the coast through studies and monitoring. These first round SMPs have been reviewed to take account of updated information.
The review of the Suffolk SMP, for the coast between Lowestoft Ness and Felixstowe Landguard Point, began in 2007 and the plan and documentation were finalised in the early part of 2010. This SMP was known previously as SMP Sub Cell 3C and is now named SMP 7 due to a decision to renumber SMPs sequentially clockwise from the North East. The final report is one of the second generation Shoreline Management Plans, or SMP2s.
Suffolk Coastal and Waveney District Councils are the coast protection authorities, with powers to undertake coast protection works (protection against coastal erosion and the encroachment by the sea). They are the bodies, under the Coast Protection Act 1949, who have a duty to regulate coast protection works undertaken by other organisations and individuals.
The Environment Agency (EA) is the authority responsible for sea defence (management of coastal flood risk). It also has an overview, or supervisory, role with respect to both sea defence and coast protection. These three organisations work in partnership with each other and with all those that have an interest and responsibility along the Suffolk coast. These include Natural England, with their advisory role on nature conservation, Suffolk County Council, English Heritage and the Suffolk Coast and Heaths Area of Outstanding Natural Beauty Unit.
The production of the SMP was managed on behalf of Suffolk Coastal District Council by Terry Oakes Associates Ltd and the technical study was carried out by Royal Haskoning, supported by ABPmer. The approved full SMP can be found at http://www.suffolksmp2.org.uk/
In October 2010 work got underway on a community partnership scheme to provide protection to part of the threatened coastline at Thorpeness.
The phase 1 emergency protection works were completed in February 2011. An extended Phase 2 of the works started on site in September 2011 and was completed on 3 February 2012.
Phase 2 involved strengthening the existing failed gabion (rock-filled wire baskets) structure using a combination of sand filled geo-textile bags and localised rock infill.
J Breheny Contractors Ltd laid a grand total of 1,856 bags, eight to ten layers deep, on over one and a half square miles of geo-fabric. This has created a 600 foot toe-shaped structure that will provide vital support to the existing structure. Work was due to be finished by mid-January but has been completed two weeks earlier than expected.
As the bag laying has been completed early and some money has been saved, some additional repair work was done to repair and reinforce the existing gabions meaning that work extended into early February.
The project has seen a range of partners involved, with the Environment Agency and Natural England being very supportive in the planning and design stages, along with local landowners Suffolk County Council and the Ogilvie Estate.
There has been very close liaison throughout the two phases with community representatives which has proved invaluable and has built strong links which will help monitor and manage the works in future.
Most of the funding is from the Government via the Environment Agency, with the remainder coming from Suffolk Coastal District Council and most importantly local residents, as without their 㷬000 commitment the scheme would not have got financial backing from the Government.
The Cromer Coast Protection Scheme is valued at around Million, to be implemented in two phases.
The purpose of the Scheme is to refurbish the existing sea walls and groynes to prolong the life of the defences through a targeted programme of works . The first phase will focus on the most urgent sections of wall, largely the older sections in the town centre plus works to the groynes to ensure their integrity.
The older walls are listed Grade II and so their profile and composition is being retained as far as possible. Thus the works comprise a mix of partial and complete encasement, sheet pile toes and apron refurbishment. The groyne field is presently effective in retaining a beach, so it will not be changed, merely refurbished.
NNDC has appointed URS as its principal consultant, for the whole of Phase 1. Team van Oord has been engaged to provide a contractor input to the design phase. The project is being managed by Peter Frew Associates.
Tenders will be invited in late Spring 2013, with a start on site programmed for the Autumn.
This study was identified within the Kelling to Lowestoft SMP. Originally conceived as a complete review of the strategies covering this length of coast, it has been refined to focus on the areas where the SMP could only take a view at the very highest level. It is intended that the study will lead to programmes of work to be undertaken by NNDC (Cromer to Cart Gap) and by the Environment Agency (EA). By focussing the study the cost has been reduced the cost by around 70%. This approach has found favour with the EA and is being promoted elsewhere as a potential model that can (in the right circumstances) deliver the desired outcomes for much reduced costs. The study is being undertaken by Mott MacDonald, with project Management by St La Haye Ltd.
The Wash SMP suggests that defence of the area to the south of Hunstanton will not be sustainable beyond the first epoch. In parallel, grant aid for capital maintenance is ending. The SMP also suggests that the cliffs to the north of Hunstanton should not be defended. Only Hunstanton town has a Hold the Line policy for all three SMP epochs.
Royal Haskoning DHV has been engaged to develop a strategy for the management of the whole frontage from Wolferton Creek north to Old Hunstanton. They will utilise, in part, studies undertaken by Risk and Policy Analysts Ltd. These investigated possible options for community / business contributions to coast defence management and was commissioned by the Borough Council of Kings Lynn and West Norfolk (KL&WNBC) using Defra Coastal Change Pathfinder grant.
The Strategy is being managed jointly by the EA and KL&WNBC who have set up Key Stakeholder and Advisory Groups to ensure active community engagement and input. The KSG is chaired by Cllr Brian Long of KL& WN and the Advisory Group by Peter Frew representing the EA Regional Flood and Coastal Committee.
The Essex and South Suffolk Shoreline Management Plan identified the vulnerability of the frontage and recommended a policy of 'Hold the Line'. However, the SMP also highlighted important issues that need to be addressed in order to achieve this for the future, in terms of coastal processes, economics and funding; alongside important social and environmental opportunities and constraints.
Following on from the SMP findings, Tendring District Council, the Environment Agency and Essex County Council are developing the Clacton & Holland Coastal Management Plan. The Plan will set out to:
1. Produce a technically viable solution which: takes into account maintenance of the defences;
- is flexible so it can be adapted in the future if things change; and
- is safe to construct
2. Take into account environmental considerations to:
- protect and enhance the environment, historic features and local amenities;
- consider social impacts and provide enhancements to the community where possible;
- to address the impacts of climate change
3. Take into account economic and funding considerations to:
- find the best cost effective solution
- find a solution and method of phasing spend which is fundable and deliverable
- increase opportunities for collaborative funding
- tie in with local regeneration plans and support the local economy
It is intended that the final Plan will provide a vision for how the frontage can be managed for the next 25 years and offer options for the longer term (the next 100 years).
Southend Council is in the final stages of preparing their Shoreline Strategy, designed to guide the implementation of the Essex and South Suffolk SMP in the Southend frontage, over the next 100 years. A draft has already been approved by the Council's Cabinet and has gone through a presentation to Environment Agency's Large Project Review Group (LPRG) for adoption. They have requested some re-drafting based on slightly different strategy boundaries, and it is expected that the strategy will be re-submitted to LPRG later this Summer.
At the eastern extent of the Borough of Southend, lies at the mouth of the inner Thames Estuary. The emerging Shoreline Strategy identifies a 1km section of wall in Shoebury as sub-standard, and with justification to improve the Standard of Protection from 1 in 50 years to 1 in 200 years. Because the strategy has yet to be approved by Environment Agency, and because the project has been brought forward to be able to take advantage of the availability of a substantial quantity of engineering fill material, project options have been prepared and presented in a separate Project Appraisal Report. The project relies on funding contributions from the Regional Flood and Coastal Committee, the Borough Council and a private contributor. It is presently making progress through a stormy public consultation process, which is intended to inform the finally selected option.
