We have been developing plans with the community in Clementhorpe on potential options since November 2017. We have now identified the most appropriate solution for the community. This is one of the first locations within York where work will begin to provide better protection from flooding.

Our assessment

The community of Clementhorpe is situated on the right bank of the River Ouse between Skeldergate Bridge and the outer ring road.  Since the publication of this plan in 2016, further investigation has confirmed that all of the properties at risk in this area (approximately 150 homes) are between Skeldergate Bridge and St Chad's Wharf – just upstream of Nun Ings. This forms the Clementhorpe flood cell.
 

The flood cell can be split into two distinct areas:

  • Clementhorpe: this is a residential area above Rowntree Park characterised by a combination of modern flats and traditional terraced houses. This includes the Rowntree Caravan Park and Roomzzz hotel development – formerly the Parkside Commercial Centre.
  • South Bank: this includes Rowntree Park and the area downstream of Rowntree Park. Rowntree Park is a registered Historic Park and Garden and a valuable local amenity. The area downstream of Rowntree Park is characterised by semi-detached properties and riverside apartments at St Chad's Wharf. The Millennium Bridge is a key access point to the city centre as well as part of National Cycle Route 66. The riverside green space below Rowntree Park functions as a floodplain when the river is high. 

The Clementhorpe flood cell split into two distinct areas.

Clementhorpe

This area has been affected by flooding on several occasions, including in 1982 when 28 properties were flooded on Lower Ebor Street. A flood wall on Lower Ebor Street was installed after the 1982 flood. This has come close to overtopping in more recent flood events. The street named Clementhorpe often floods, restricting access to properties.   

Our proposal

We are proposing the following improvements to the flood defences in Clementhorpe.

  • Raising the corners of existing walls along Postern Close and the construction of a new flood defence wall between the Postern Close buildings;
  • A new floodgate across the end of Clementhorpe;
  • A new flood wall to the exterior of Waterfront House;
  • An additional step to existing steps between Waterfront House and Dukes Wharf;
  • Raising of the private road level at Duke’s Wharf;
  • A new flood wall on the Duke’s Wharf access road up to tie in to the newly raised road level;
  • New flood wall to the north of the Roomzzz site;
  • Increase of height to existing flood defences in the Caravan Park which will meet high ground at the North East end of Rowntree Park;
  • Installation of penstocks and agreement of temporary pumping arrangements, where required, with Yorkshire Water to ensure no additional risk of sewer flooding.

Timescales and Next Steps

Planning submission

On 6 March, we held a public drop-in at Clementhorpe Community Centre to update residents on our revised proposals for the area before submitting them to City of York Council for planning approval. The information displayed at the event can be found in the 'Related' section at the bottom of this page. 

We have submitted our proposals to City of York Council for planning approval in  March 2019. You can view this application online via the CYC planning portal (ref 19/00570/FUL).  Our Planning Statement can be viewed here:

Planning Statement

If the planning application is approved, construction work will start during the autumn of 2019 and finish at the end of 2021.

Traffic Management and Construction Site Access

On the 8th May 2019, we held a public drop-in at Southlands Methodist Church to inform residents of our initial plans for accessing the site during construction. This is summarised in the document below and a copy of the information displayed at the event can be found in the 'Related' section at the bottom of the page, titled 'May 2019 Engagement Material'.

South Bank

Flooding near Rowntree Park in 2005 (Photo supplied by Graham Knott).

Rowntree Park floods regularly. There are a small number of properties at risk of flooding directly behind the park with some reporting flooding in 2000, 2012 and 2015. Downstream of Rowntree Park, properties along Terry Street, Butcher Terrace and Reginald Grove are at risk of or have experienced flooding in the past.

Our proposal

We identified three different options to reduce the risk of flooding. These options were presented to the community between March and May 2018 for feedback.  Information on these options can be downloaded from the links at the bottom of the page.

We are currently finalising a report describing the engagement work we have carried out in this flood cell. This will be uploaded to this page as soon as possible.

Having considered these options from a technical, economic and environmental point of view, as well as feedback received from local residents, the most appropriate solution for South Bank is Property Flood Resilience (PFR).

We completed threshold surveys of the flood zone in the South Bank area in 2017. These identified those properties we believe are at risk of flooding and as such are eligible for PFR. If your property is not shown on the map below as being eligible, but you have experienced flooding in the past and can provide evidence of this, then please contact us at yorkfloodplan@environment-agency.gov.uk

Timescales and Next Steps

With the PFR framework being new, our original timescales have unfortunately slipped. We encountered some unforeseen difficulties in our internal procurement process. We have appointed a supplier and are now in the process of agreeig a contract with them. We will be in touch with residents when we are ready to progress to the next stage.

 

The Foss Confluence to Fulford Flood Cell

You can find the September 2019 newsletter here:

The flood cell covers the area directly below the confluence of the rivers Foss and Ouse near Blue Bridge Lane and continuing south to Fulford Ings. It is located on the left bank of the River Ouse, downstream of the Foss Barrier. Properties within the flood cell include modern riverside apartments, Edwardian town houses and bungalows. The flood cell also includes St George’s car park. An important feature in the flood cell is New Walk, a tree lined riverside footpath created in the 1730s. The opening of the Millennium Bridge in 2001 has increased footfall into the area and it has become a key access point to the city centre as well as being on National Cycle route 66.

Our assessment

Flood risk in the area includes flooding directly from the river Ouse, seepage through the boundary wall running along New Walk, as well as high groundwater levels when the river is high. There are 18 properties in this area that have either experienced or are at risk of internal flooding, of which ten properties are on New Walk and eight around St Oswald's Street.  

The Foss Barrier

We have carried out modelling exercises which show that the upgraded pumps at the Foss Barrier could cause a rise in river levels downstream of up to 8 centimetres, thus increasing the risk of flooding belwo the barrier. However, this is an absolute worst case scenario, based on a number of highly unlikely assumptions. The first assumption is that the barrier would need to pump at maximum capacity for 90 hours. This is extremely unlikely as the Foss does not peak for long periods of time. On Boxing Day 2015 the peak flow lasted less than an hour. The second assumption was that this would occur simultaneously with a flood on the Ouse on a scale never seen before in York.  A more reasonable worst case scenario, where the Foss peaks for less than an hour, coinciding with an extreme flood event on the Ouse (worse than ever recorded), would result in a 1 centimetre increase downstream. The risk of flooding of this scale occurring again on the Foss will also be reduced by the upstream storage scheme we are proposing for the wider Foss catchment.

Our proposal

We identified several options to reduce the risk of flooding in this flood cell. Having considered these from a technical, economic and environmental point of view, we have determined that the most appropriate solution is Property Flood Resilience (PFR). The number of properties affected by flooding in this area is low, whilst many of the options considered would be expensive to build. We therefore cannot justify this expense, according to Defra's criteria for funding. For more information about how we have arrived at this solution please see the New Walk Feasibility Note at the bottom of the page.

We completed threshold surveys of properties in the flood zone in the Foss Confluence to Fulford area in 2017. These identified properties we believe are at risk of flooding and as such are eligible for PFR.

Timescales and Next Steps

Residents whose homes were surveyed should have received their individual PFR report and had a chance to comment on this.

We wrote to residents in October 2018 to request confirmation of their intended inclusion in our PFR scheme for the Foss confluence to Fulford flood cell. Confirmation was requested by 26th October 2018. We received feedback from 62% of residents. Since then, we have sent letters and door-knocked those properties which didn't repsond the first time around.

With the PFR framework being new, our original timescales have unfortunately slipped. We encountered some unforeseen difficulties in our internal procurement process. We have appointed a supplier and are now in the process of agreeing a contract with them. We will be in touch with residents when we are ready to progress to the next stage.

 

The Germany Beck Flood Cell

We are working closely with City of York Council to develop an effective solution to the issues in Fulford. Ground investigations have commenced to inform the viability of works.
