Frequently Asked Questions
How has the project been affected by the outbreak of coronavirus?
Nottinghamshire County Council is working in line with the government guidelines in response to the coronavirus pandemic.
This initially led to the closing down of the active construction, relocation of office-based staff to home working and stop to any site visits for meeting, design or survey purposes. In the meantime, the Southwell Trail site was made secure and safe, pending a resumption of construction work.
Following the recent relaxation of guidelines for working, Via East Midlands Ltd (Design and Construction of engineering schemes) is preparing to return to site; at the moment this is planned for later in June 2020. Design work for the wider project is still in progress with Via East Midlands Ltd design staff working from home and since the middle of May 2020 able to visit site again. Via East Midlands Ltd is liaising with Nottinghamshire County Council and key stakeholders on a regularly basis using digital platforms.
In common with many other engineering projects, the coronavirus will impact on the overall project, particularly in terms of programme. However, Via East Midlands Ltd is working closely with Nottinghamshire County Council to understand and keep that impact to a minimum.
Why is Halam Road still flooding despite super gullies being installed?
The super gullies were tested during a storm on 9 February 2020. You can read more about this on the Southwell Flood Risk Management page.
Who makes the decisions about the project?
The County Council is responsible for the overall delivery of all elements of the project. The project is managed through a board made up of key partners including:
- Nottinghamshire County Council (Project Lead)
- Via East Midlands Ltd. (Design and Construction of engineering schemes)
- Southwell Flood Forum (Community Representatives)
- Trent Valley Internal Drainage Board (Watercourse Management)
- Southwell Town Council (Community Representatives)
- Newark and Sherwood District Council (District Representatives)
- Environment Agency (Lead Funding Partners)
- Severn Trent Water (Utility Company)
When are things happening and where?
Main site works to install drainage and natural flood management measures have now concluded. We have further minor works which will begin in late Spring 2020.
Works on the public highway were completed before Christmas and we are now on-site on privately owned land which contains the attenuation pond. We are improving drainage channels to direct flood water to the pond and are also working to increase the amount of water that the pond will be able to hold during flood conditions.
We will need to undertake site clearance works in order to improve the current cross field drainage system and this is expected to take place during the spring. Site clearance is also needed in order to carry out the main works on the Southwell Trail, and these are expected to begin imminently.
This project will increase the amount of temporary flood water storage and the speed the water can travel away from the built-up area. Works will also involve the creation of a linear channel alongside the trail.
We are working on the detailed design for the Potwell Dyke off Church Street. The focus of this project is to provide temporary storage of flood water upstream of properties in Easthorpe and beyond. We anticipate that works will commence towards the end of Summer 2020. Associated investigations continue throughout Southwell to inform our design process.
Lowes Wong School:
Works began over the Summer to reduce surface water from the site which included the installation of sustainable urban drainage systems. Developments at the school site will also benefit residents of the Ropewalk and neighbouring areas and we hope that pupils will soon be able to enjoy a new ‘water orchard.’
Property Flood Resilience:
We have now received signed customer agreements from property owners and have agreed an installation date for the works to begin. If you have received an agreement and have not yet returned this to us, please do so at your earliest convenience to allow us to schedule the works.
Will the new development opposite Halam Hill pond make things worse?
The Miller homes development proposals were scrutinised during the planning stages and Nottinghamshire County Council ensured a robust surface water management proposal was developed for consideration and subsequent approval prior to planning approval. The surface water discharge from the completed development site will be controlled to a limited rate of discharge to the attenuation pond. This rate is significantly lower than the pre-developed site. Any other flows will be captured by the super gullies and the flood attenuation mound in Halam Road.
Why has the historic idea of a pipe between Halam Hill and the River Greet been abandoned?
The concept of connecting Halam Hill and the River Greet was conceived over 25 years ago. The Southwell Flood Alleviation Business Case was developed following a detailed strategic review of the whole catchment. All options were reviewed, costed and ranked on basis of the degree of protection and cost effectiveness. The current strategy does not include the historic scheme as it did not meet technical and financial criteria. Whilst we understand there is significant interest locally in the revival of this proposal in the future, it is not within the scope of the current works.
Once the Southwell Flood Alleviation Scheme is complete, will Southwell be free from flooding?
Southwell Flood Alleviation was developed to address the most severely affected areas. The works are underpinned by a flood risk management strategy which has been developed to manage the risk in the most effective way. Issues including increasing development, impermeable areas, water run-off and infrastructure will be continually addressed.
Why have some properties been offered property flood resilience and others haven’t, and why has this been done first?
Property Flood Resilience (PFR) measures are bespoke proposals which protect individual homes from flooding. Properties which have not been offered PFR will instead benefit from an increased level of protection from the schemes which are currently being installed.
We have designed the scheme to benefit homes across the catchment as a whole and will be continually reviewing which properties are protected by each element of the project as the designs develop.
