Bridgwater Tidal Barrier EIA Scoping Opinion – a lack of knowledge, vision or a rubber stamp?

All large infrastructure projects require an assessment of its impact on the environment. The Bridgwater Tidal Barrier is no different and as one of the UK’s first real climate change driven projects it is important that the long term impacts are understood not just the immediate aftermath of the construction process.

Screening and Scoping Opinions (Environmental Impact) Screening is the process of deciding which projects require an Environmental Impact Assessment (EIA). A scoping opinion only considers what information should be included in an EIA.

What we know

  1. Infrastructure projects whether the BTB, the expansion of London’s railways in the 1800s or the construction of the UK’s motorways in the 70’s have well established long term impacts on our environment as society adapts to the change the project imposes on the area. In Bridgwater’s case the planned BTB removes 3 to 400Ha of potentially development land close to Bridgwater and its existing communication links (J23 of the M5). With the topographical constraints imposed by the M5, the railway and the River Parrett the other options for future development are few.
  2. Bridgwater will in the 100 years of the BTB operation continue to expand and grow and a conservative assessment of the additional area of Bridgwater developed for housing and employment will be around 40% of Bridgwater’s current footprint. Bridgwater’s expansion has to go somewhere and it will impact on the environment beyond the immediate area of construction.
  3. The water that will flood onto the the farmland with increasing frequency will be saline and will change the nature of the land destroying valuable freshwater habitat at Chilton Trinity and at Pawlett Ham’s and the ability to grow food.
  4. A warming climate will see the arrival of new species in particular the Asian Tiger Mosquito to existing open water and bringing the inter tidal habitat up to Dunball as proposed by the Parrett Estuary Flood Management Strategy to the edge of Bridgwater’s habitable area threatening the health of people in North Bridgwater, Pawlett, Chilton Trinity and Puriton and the housing developments on King Drive. It is not unreasonable to consider that open water may well be considered in the same way as in other warm climates as being breeding grounds for mosquitoes and a source of the Zika virus and Denge Fever.

What the EIA opinion ignored.

  • The impact of pushing the economic development onto the Quantock Hills
  • The impact of building on the levels to the east of Bridgwater
  • The impact of seawater on the land.
  • Increasing the rate of salt ingress into the land due to retention of saline water in the borrow pits.
  • potential habitat creation for invasive species and the health threat they make to the local population.

The work done in in this document seems to irrationally imagine that

  • Bridgwater does not expand for the next 100 Years
  • Environmental changes will only be driven by sea level rise
  • The environmental impact is only in the immediate area of the scheme

There is a complete lack of appreciation of the what the BTB scheme entails and its impact on the environment. It studious ignores the wider impacts of this scheme and allows the development to move forward with little or no consideration of the impact. It offers no visibility to the public of what impacts may occur in the next 100 years. EIA are by nature speculative and in the case of the BTB scheme the applicants should provide a wider and more comprehensive assessment.

The EIA is simply inadequate and as a consequence make the work done incomplete and questionable in its efficacy. It is a continuation of the lack of vision and understanding of this project, a project that is key to the long term future of Sedgemoor and Bridgwater.








Somerset’s 20 Year Flood Action Plan is not a Plan

Has anyone noticed  there actually isn’t really a plan for managing flooding in Somerset  be it Tidal or Fluvial. Lots of headlines and pictures of grandstanding councillors on river banks  but little substance.  Our particular collective flood Emperor has no clothes whilst the myth that somehow the Bridgwater Tidal Barrier (BTB) is part of the solution to the avoiding a repeat of the 2014 flood is allowed to persist. People imagine that things are being done and there is a big picture somewhere. There isnt.

The Somerset 20 Year Flood Action Plan is little more than a  maintenance list that should have been done and wasn’t; it is a complete misnomer. In three years since the 2014 flood  there is no  big plan looking forward  the next 200 years. There is no context that  explains where the value of all the money being spent is.

There is no excuse for such short sighted behaviour by our officials and elected representatives. At least the Somerset Rivers Authority (SRA) carried out an economic impact assessment of the 2014 flood which is more than the EA and Sedgemoor District Council (SDC) have done for the Bridgwater Tidal  Barrier.

The development of new ideas  seems to be more akin to those seeking alternative medicinal remedies; they seem to be ones that will turn the Levels into some theme park rather than look at something that can be delivered over the decades and centuries ahead. The  Managed  Retreat (Realignment) of our coastline is not a panacea to rising sea levels; it has its place but  needs to be challenged when there are viable options.  Giving the EA the excuse and licence to do little or nothing is not acceptable. Those involved with W&WT and the RSPB as consistent beneficiaries of these  EA policies and alongside Natural England makes an unholy alliance  that is no friend of Somerset’s people.

Plenty of councillors are sat on committees and they should be ensuring rigorous debate and the publishing of useful information rather than the almost complete lack of detail in the public domain. The private sector would not be allowed to get away with this lack of transparency or vision.

Since 2014 when it was rushed together for political expediency  little has been done or achieved whilst show case projects are not what they seem

Bridgwater Tidal Barrier

Despite knowing that  the rise in sea level  has no recognised end date Somerset has decided on a  100 year scheme. Our King Canute moment.

We are going to build a scheme that cannot be easily extended or modified knowing full well that something else will be needed in the future but we haven’t decided what. A scheme that  unlike any conventional tidal surge barrier  it is  actually to be in the town rather than down stream and at the mouth of the river. Bridgwater in  probably 10 rather than 100 years will have enveloped the proposed barrier site.  A solution with built in obsolescence that  can be bypassed on day one does not seem a great idea. Children born today may see the BTB torn down. Why would Bridgwater  buy it?”

Options such as closing the gap between Stockland Bristol  and Pawlett Hill less than 2 Km  ( 1.3 miles) long compared to around 15 km (10 miles) both banks from Combwich to the selected site in Bridgwater or 7.5 Km  if you allow Pawlett Hams to go the way of Steart Peninsula.

Two option studies paid for by the taxpayer and Combwich  not even considered as an option in either and the  backdoor flood route at Walpole still not acknowledged when the EA visits landowners. The credibility of the EA , its consultants and our oversight committees is very poor.

King Sedgemoor Drain Improvement

The King Sedgemoor Drain improvement is a Fluvial conveyance scheme that cannot reach its full potential because of the location of the tidal BTB upstream of Dunball Clyce. The EA in this matter described themselves in recent correspondence as the SRA’s sub contractor.

Silos

Flood schemes are kept in silos of fluvial and tidal rather than in developing a single holistic solution for Somerset. The EA and other organisations make it very difficult  to see the full picture. There is a serious lack of transparency,  accountability and independent review in the process.

By 2024 nearly £100m will have been spent and the Levels will still flood. The Bridgwater Tidal Barrier is seen and portrayed as a Bridgwater only scheme where as moving it downstream  of the KSD outfall would increase conveyance  under fluvial conditions benefiting the districts of Taunton Deane and South Somerset. The SRA is nowhere to be seen generating debate and  bringing together people to achieve a wider benefit to Somerset with state and local ratepayers money which was its reason to be created. The SRA’s one big opportunity missed. This is notwithstanding the missed economic opportunity for West Somerset

Transparency

There is more information in the public domain about EDF’s Hinkley Point C power station then there is about these schemes especially the Bridgwater Tidal Barrier. It appears  the EA did not want the Chilton Trinity  and Pawlett Hams landowners to be aware of  what would not be done to protect their land choosing to hide behind the rather opaque Parrett Estuary Flood Risk Management Strategy. Something noticeably low key to the point of invisibility  in the EA’s 2016 consultations at the Bridgwater Art’s Centre.

The reasons  that undertakings given by the EA and SDC in Protecting Bridgwater and the Somerset Levels & Moors from Tidal Flooding-Flood Risk Management Review -November 2014 were never followed through and just quietly dropped has never been explained.

No imagination  and no vision for our children’s future

With a blank sheet of paper and little or no restrictions on what we might do to protect the South Somerset Levels including areas of Sedgemoor, Taunton Deane and  South Somerset there is still a blank piece of paper. Rarely has such an opportunity been squandered.

There is nothing that explains what happens to the Tidal Surge Barrier when we cannot raise the banks any longer which in reality we cant now and Pawlett Hams and Chilton Trinity have become mudflats/ salt marsh  and the cost of building downstream  prohibitive.

What we do have is lots of committees

Wessex Regional Flood and Coastal Committee (RFCC)

Board of the Somerset Rivers Authority (SRA)

SRA Joint Scrutiny Panel

Somerset Drainage Board Consortium (IDB)

Its interesting to note how many people sit  on more than one of these committees. These committees  have people with no engineering knowledge or experience apart from the EA & IDB and all EA’s donkey work is done by US and Canadian third party consultants with no attachment to the area. The EA’s contribution to Somerset is questionable now as they have been reduced to little more than a middle man.

we must also not forget the groups

  • SRA  Management Group
  • SRA Technical Group
  • Bristol Channel Strategic Coastal Group
  • South West Coastal Group
  • Southern Coastal Group

It really is time that Somerset had  a suitable organisation capable of bringing a long term vision to secure the future of Somerset. Whilst attendance at committees is so lucrative  nothing is going to get done .  The EA is not a delivery based organisation and needs to be changed or replaced.  The SRA has no structure or suitable people able to develop and execute the vision and solution we need. The system  we have is clearly not fit for purpose.

The situation for Somerset, the rest of the West Country and no doubt other regions of the UK is that they need their own independent Engineers with local knowledge. Engineers able  to provide continuity  in advice to the committees and oversee the EA and IDB and other agencies.

We cannot afford

  • that each agency (EA, Highways, Rail) continues to builds its own thing, we need to combine flood defence with other infrastructure works.
  • that strategic flood decisions can be left to seconded senior local authority officers  with little or no knowledge of the subject.
  • the lack of an independent peer review process.
  • The lack of transparency – there is nothing published on the BTB website that tells you why.  There is little value value in an undated progress report  that can be found there  that does not measure progress. 
  • all these organisations whose main purpose seems to be to invite people from other groups to attend their meetings at our expense.

WE NEED A PLAN and we need to end the Flooding Golden Goose. 

on the 14th of July 2017  a meeting of the Scrutiny Committee  will take place in Taunton . It is open to the public.
