I said that I would remain neutral, unbiased ... on the fence (if you wish) and I intend to do so. But that shouldn’t stop me from pointing out items that are clearly wrong or misleading. One of the problems facing the public in a situation like this are the inaccurate claims designed, it seems, to stir up sentiment, and thereby support, for a cause. Below is just such an extract from the website Lewes Conservatives dated 5th February 2008.
‘The Environment Agency plans to flood the Cuckmere Valley by breaching the embankments allowing the incoming tides to swamp the valley with seawater and by non-clearance of the river mouth, which will cause flooding upstream and will endanger the A259. When visiting the site Jason Sugarman said “This deliberate flooding will mean the loss of four footpaths in the beautiful valley which will decimate the local tourist trade. These age old meanders are a recreational and educational resource for generations of students and local families, that will be lost under mudflats.”’
Now many of statements in this piece – presented, apparently as facts – are actually just Mr Sugarman’s opinion (albeit a misinformed one ... I trust!) Please note, therefore that:
1) There is no evidence that the Environment Agency’s plans will cause flooding upstream and in fact one of the great benefits to tidal mudflats and salt marshes is their ability to act as a natural barrier against flooding. [See: RSPB Article and Intertidal Salt Marsh Survey]
2) There is no evidence that the tourist trade will be decimated (which, if I’m going to be truly pedantic means ‘reduced by 10%’ and is frequently misused by ignorant people who seem to think it means something completely different). I have heard this argument used many times and the truth of the matter is that for all we know more people might come to visit the Cuckmere after it becomes a salt marsh.
3) The meanders are silting up anyway and will disappear eventually of their own accord. Allowing the sea back in probably won’t help, but it’s not fair to blame the Environment Agency for their disappearance when keeping things as they are will result in the same outcome.

This is the proposal put forward by Nigel Newton on behalf of Rescue the Cuckmere Valley.
1. Proposal
1.1. The proposal is to raise the height of flood protection banks alongside the River Cuckmere by 300mm, from Exceat Bridge (adjacent to the Golden Galleon public house on the A259) to the sea. This stretch of river was canalised in the nineteenth century and the flood banks are relatively straight manmade features running either side of the channelled main course of the river. The flood banks double up as public footpaths, giving access from Exceat Bridge to the beach and coastal paths. The Vanguard Way (north-south) public path passes along the western side of the valley floor within Lewes District.
1.2. At the south end, the district boundary follows the course of the river and the proposal therefore includes raising the height of the banks which are within Wealden District. Planning applications have therefore been submitted to both Councils for the respective development within each area. This report considers the planning application which has been submitted to Lewes and, further, considers the response from this Council (as consultee) to Wealden DC on the application submitted to that Authority.
1.3. The Cuckmere Valley at this point is open and undeveloped. To the west of the river is lowland meadow and to the east is coastal floodplain and grazing marsh, together with the original meandering course of the river which forms a striking feature in the landscape. This area, including the Seven Sisters Country Park, is popular and is visited by substantial numbers of visitors enjoying the scenery and using the paths.
1.4. As indicated above, the proposal is to raise the height of the existing banks along both sides of the river by 300mm. The top surface would be level and grassed, and approximately 1.5m wide so that the existing footpaths are reinstated following completion of the works. A new bird hide would be constructed approximately 750m south of the Exceat Bridge.
1.5. The applicant’s agent has submitted the application as an alternative to an earlier proposal by the Environment Agency (EA) to “remove parts of the tidal protection banks and so cause tidal flooding of the fields either side of the River Cuckmere and the well known meanders”, which the applicant considers to be wholly unacceptable. The EA’s proposal did not proceed to a planning application and is currently understood to be under review, pending preparation of an Environmental Impact Assessment. The purpose of the current application is “to demonstrate that there is a reasonable and benign alternative to flooding the valley even under conditions of sea level rise…” It is presented as “a relatively low cost way of maintaining the status quo of footpaths important to the tourist industry, of visual amenity also important in that respect, and avoids dangers of erosion and environmental mishap.” The agent states that, with a net increase in sea level each year of 6mm, the 300mm increase in height of the banks would give approximately 50 years extra life to the tidal banks and the existing landscape, which would give time for “much mature reflection, and the assimilation of more definitive information on island tilt and global warming than is available today”. The agent also points out that, under the EA proposal, a right of access to the applicants property would be lost.
1.6. In total, the applicants claim that the proposal would require the importation of about 13,000 cubic metres of chalk for the raising of the banks, which is expected to generate a total of 1300 road delivery journeys, phased so as not to exceed 6 per day. Road access would be from the A259 both to the east and west of Exceat Bridge (to the west through the car park of the Golden Galleon public house), possibly requiring temporary traffic light control. Material would be delivered to temporary works compounds on either side of the river, and access to the working sites would be provided along the top of the existing tidal banks.
1.7. The application has been accompanied by supporting information covering ecological and engineering issues.
1.8. Implementation of any planning permission granted by the District Council would also require a separate consent from the Environment Agency under flood defence legislation, for works adjacent to a “main river”.

The Environment Agency is today (10 December 2008) announcing its decision to restore the Cuckmere estuary to a tidal floodplain, allowing this popular landmark to adapt to the impacts of climate change and providing great benefits to both visitors and wildlife.
Climate change, sea level rise and past interference by man have put the Cuckmere estuary under increasing pressure. Current flood defences are not high enough to cope with sea level rise, the river has not flowed through the winding meanders since the 1840’s and each year the Environment Agency spends up to £50,000 removing shingle from the mouth of the river.
Andrew Pearce, Environment Agency Area Manager for Kent and East Sussex, said: “We believe there is a better way to manage this special place. Climate change is presenting us with many challenges and the way we manage flood risk here has to change. Restoring the Cuckmere estuary to a tidal floodplain will allow the area to adapt to climate change and will bring with it great opportunities and benefits for visitors and wildlife.”
Last year the Environment Agency offered people the opportunity to give their views on the recommendation to stop maintaining the existing defences. The Environment Agency has now finalised its flood risk management strategy for the Cuckmere estuary and all those who own or occupy land in the area have now been informed of the decision to withdraw maintenance after a two year notice period.
Andrew Pearce continued: “This is a beautiful landmark and an undeveloped area and it wouldn’t be right to continually build bigger defences here. Our decision will not increase flood risk for any properties in the Cuckmere River catchment. But it will save valuable flood risk management money which can then be directed to where it is most needed to protect people and properties.”
Each year the Environment Agency spends up to £50,000 of flood risk management money removing shingle from the river mouth to enable the river to flow out to the sea and reduce the risk of flooding upstream at Alfriston and Westdean. Following the 2 year notice period, the Environment Agency will continue to do this work for as long as it is required. When the tidal floodplain is restored, the river will be able to keep itself clear. This could take up to 15 years.
Andrew Pearce added: “We do know there will be a lot of concern for the future of this popular landmark and we are not just walking away, We believe a more natural estuary will still provide plenty of opportunity for people to continue to enjoy this wonderful area and as a member of the Cuckmere Estuary Partnership we will work with local residents and businesses to identify how to manage the changes to the estuary in the future so that the public can continue to enjoy this area and wildlife can thrive.”
In its draft flood risk management strategy, the Environment Agency compared several options for managing flood risk on the Cuckmere estuary. More than 100 people responded to the draft and over 250 people attended exhibition sessions. Over half of those who responded to the consultation between September and December 2007 believed that some kind of management change needs to happen.

The Cuckmere Estuary Partnersip are organinsing three engagement events in order to canvass the views of local people on the project.
6 July, Alfriston War Memorial Hall, 6.00pm
8 July, Clinton Centre, Seaford, 10.15am
13 July, Eastbourne Town Hall, 6.00pm
Spaces are limited due to the sizes of the venues so if you wish to attend please visit their website and complete the booking form.
Pre-historic period
Before the formation of the English Channel and during periods of low sea level, the Cuckmere would have formed a tributary of the English Channel river system. As such it would have offered a natural routeway into the main body of the Wealden landscape for game herds and hunting groups of early humans.
Deposits can be seen in the cliff face on the western side of the Cuckmere Haven, containing sands, silts and gravels deposited during the tertiary and Pleistocene ages. They are complex and poorly understood, but it has been suggested that they may represent an exposure of sediments laid down hundreds off thousands of years ago by the River Cuckmere. The deposits have produced both Pleistocene mammal remains and a single flint handaxe.
Mesolithic to Roman period
Rising sea levels severed the land link between southern England and Europe around 8500 year ago, and Mesolithic groups in Britain developed a different culture to those in continental Europe. The climate became warmer, and cool tundra-like landscapes were replaced by deciduous woodlands of hazel, lime and oak, broken by isolated patches of grassland. Finds from the surrounding valleys sides and Downlands demonstrate that the area was actively used from the Mesolithic through to the Roman period and it is likely that remains of the period lie buried within deposits of the Estuary.
Studies of alluvial, colluvial (hill wash) and peat deposits in South East England indicate that there was deliberate forest clearance in the Mesolithic period to create areas for pasture and to increase agricultural productivity.
Soil samples taken from the deposits of the upper Cuckmere Valley show these deep alluvial deposits, which may represent sediment that has accumulated after the removal of vegetation during this period. As the river transported this sediment downstream, the estuary and coastal plain were formed. Much of the plain is now submerged along the East Sussex coastline.
As sea levels continued to rise during the last 8500 years, the estuary was subject to fluctuating periods of marine transgression (flooding, scouring and deposition of alluvium) and regression (drying out and the formation of marshland and meadowland).
There is some limited archaeological evidence for salt production, and finds that might indicate small scale associated settlement in the estuary during the Roman period.
There is currently no recorded archaeological evidence related to the subsequent Saxon period, although the place name Chyngton is likely to be of Saxon origin. It is possible that remains from these periods lie buried within the sediments of the Estuary.
Medieval period
In the 12th century attempts were made to create a port and on the higher ground to the west a new settlement called Poynings Town. This venture appears to have been short lived and no physical evidence for the port has been found to date. During this period it is likely that the valley floor would have been salt marsh, cut by the meandering river.
In the 13th century the manor of Chyngtynges was granted to Michelham Priory. It is likely that it was from this time onwards that the Priory began the reclamation of parts of the valley to provide valuable pasture land through the management of innings and brooks. Evidence for these embankments and ditches can still be seen today along the western side of the valley. The eastern side does not appear to have been ‘improved’ to the same degree and retains its salt marsh character.
Documentary records of the Cuckmere Levels Water Court attest to the ongoing problems of drainage, flooding and scouring, which continued until the creation of the New Cut in the mid-19th century.
Post Medieval period
During the Napoleonic Wars the Estuary was seen as potential landing point for invading armies and was defended by two garrisons of militia stationed either side of the river mouth.
Remains still survive of the eastern camp, in the form of water tanks and building platforms.
The 20th century
During the early 20th century, beach shingle was extracted from the Cuckmere
Estuary for construction, and transported using narrow gauge railway from the beach to Exceat, traces of which still remain.
Around this time, cross-channel communication cables were landed at the estuary mouth.
Conflict has also left its mark on the estuary. In World War I the area was used for the training of troops who used it as a firing range.
During World War II, as a response to the threat of invasion, the area was heavily defended with a network of pillboxes, anti-tank blocks, earthworks and mine fields. Later in the war, Cuckmere Haven was used as a decoy lighting site for Newhaven.
The World War II beach defences at the Cuckmere Estuary are still a relatively complete set, and to a large degree they remain in the same landscape setting as when they were built.

For those of you who don’t already know, the Cuckmere Estuary (also known as Cuckmere Haven) is:
“... an area of flood plains in Sussex, England where the river Cuckmere meets the English Channel between Eastbourne and Seaford. The river is an example of a meandering river, and contains several oxbow lakes. It is a popular tourist destination with an estimated 350,000 visitors per year, where they can engage in long walks, or water activities on the river. The beach at Cuckmere Haven is next to the famous chalk cliffs, the Seven Sisters.” [Source: Wikipedia]
Though generally considered to be an area of ‘unspoiled landscape’, the estuary has actually been subject to the changes of human intervention for hundreds of years and it is this intervention, or to be more precise the proposed revision of it, that lies at the root of the current controversy.
So what exactly is the problem? I shall attempt to explain. Please pardon the boxing metaphor.
“Sea levels on the south coast of Britain are predicted to rise by over a metre during the next century, and the frequency and intensity of storms caused by climate change is expected to increase.
As well as the problem of sea level rise and the threat of flooding, human intervention in the past has led to a number of problems at the estuary. The meanders are silting up, because there is no flow through them. The shingle is not naturally being replenished, leading to the erosion of the beach. And the man-made river walls and flood banks are coming to the end of their useful life.
In December 2008 the Environment Agency published its decision, under its Flood Risk Management Strategy, to withdraw maintenance of the river banks. Under government guidelines, public money cannot be spent on rebuilding and enlarging the sea defences, as there are no homes at risk of flooding in area.” [Source: Cuckmere Estuary Partnership]
This proposal has met with some severe criticism and opinion is currently split as follows:
In the red corner we have an affiliation of organisations, led by Natural England (formerly English Nature), the Environment Agency and the National Trust who have formed the Cuckmere Estuary Partnership. They have put forward a proposal to restore the Cuckmere Estuary to “...a naturally functioning estuary which will be self sustaining, reducing the need for engineered solutions and increasing the flood storage capacity of the flood plain.” They plan to adopt a process known as ‘managed realignment’ whereby “...working with, rather than against, natural coastal processes, the estuary and its wildlife would be able to adapt to sea level rise, creating a mosaic of saltmarsh and mudflats. [By doing this] We would be able to maintain footpaths and recreational use of the area, preserve features such as the meanders and the beach, and limit the impacts on local businesses.”
In the blue corner we have a group of local residents and businesses – who seem to be led by Nigel Newton, the founder and Chief Executive of Bloomsbury Publishing Plc and owner of one of the Coastguard Cottages overlooking the estuary – who do not wish to see this managed realignment for a number of reasons and are campaigning for the continuation of existing sea defences in order to preserve the Cuckmere estuary as it is. The website Rescue the Cuckmere Valley seems to represent their agenda. This is what they have to say about the Cuckmere Estuary:
“The Cuckmere Valley near Seaford, East Sussex is an area of unspoilt natural beauty that attracts 450,000 visitors a year. Here the River Cuckmere meanders across green fields grazed by cows and sheep before sweeping into the English Channel below the majestic Seven Sisters cliffs. Together with the Coastguard Cottages in the foreground this view is the very symbol of England. Cars are kept at a distance and visitors are free to wander along the banks of the river, communing with nature.”
Their objections to the proposal are that managed realignment will lead to the collapse of the sea wall which protects the Coastguard Cottages, endangering their future; create many years of mud until salt marsh develops and this only at the fringes leaving vast areas of mud flats; increase the flood risk for towns such as Alfriston and Littlington; subject the A259 to a greater risk of flooding and possible undermining by the meanders; remove the habitat of many creatures, including badgers, that inhabit the valley; lead to the loss of the beach on the east of the river once the river is reverted to its original course next to the Seven Sisters; lead to the loss of popular riverside footpaths and damage local business as mud is less attractive than the grass downland scenery.
The controversy has raged on now for the best part of a decade with no apparent resolution in sight. Though managed realignment is still the preferred option of the Cuckmere Estuary Partnership and its supporters, opposition from the blue corner has prevented any progress on the plan and in December 2008 Eastbourne MP Nigel Waterson renewed calls for a public enquiry into the affair.
What follows is my attempt to present the facts, debunk the lies and try to put forward a balanced view on the controversy. Please note that I have no agenda other than my own desire to understand what is really best for the Cuckmere Estuary. I will, for as long as it takes to reach a decision, canvass the views of those parties involved and present them without bias.
