1.  Summary of achievements across the Programme

Following the floods of December 2015, the government allocated additional funding to the Environment Agency to better protect 2,000 properties in York, including upgrading and refurbishing the Foss Barrier and its surrounding infrastructure.

Below are some key figures which highlight our achievements.

2.  Engagement highlights

Throughout the delivery of the York Flood Alleviation Scheme, we made efforts to engage proactively with the public and all other interested stakeholders on the plans and progress of our works. We have adhered to the following engagement principles:

·        We will be proactive and transparent and ensure that our information is accessible to the public and other interested stakeholders

·        We will use the most appropriate methods and tools of engagement dependent on the audience and key engagement objectives

·        We will make time to involve people properly

·        We will utilise key dates in the programme as opportunities for targeted engagement

·        We will utilise opportunities to engage, influence and build strong relationships

·        We will be honest, open and clear about what we can and cannot do to ensure that realistic expectations are set with the public and other stakeholders

·        We will act upon information received from, and provide feedback to, our stakeholders

·        We will keep internal stakeholders and colleagues informed of our activities

 

Below are some key figures which highlight our efforts and success with engagement.


3.  Our response to January Floods  

Following the Met Office’s announcement, that 2022 was the hottest year on record for the UK with average annual temperatures reaching over 10°c for the first time, January saw parts of the country in a cold snap with snow seen in places. Freezing temperatures were followed by significant rainfall which caused flooding across parts of the country including here in Yorkshire.

  

The Ouse in York peaked over the Weekend of 14/15th January, reaching 4.1m at the Viking recorder. It is estimated that our defences, including those newly completed and upgraded, helped protect around 600 properties from flooding.

 

Here are some images taken from the Skeldergate and Clementhorpe areas in York.

A new flood wall along Leeman Rd from Westgate Apartments to a new embankment in the grounds of York City Rowing Club, with demountable flood barriers across the main and second entrance to the Memorial Gardens. A new, larger flood gate under Lendal Bridge. Raised height to existing flood wall along North St with replaced flood gates, including increased width to northernmost gate to improve pedestrian flow.

Completed Feb 2022

B8 - Clementhorpe

7,717

135

A new flood wall in front of Waterfront House. Raised steps between Waterfront House and Dukes Wharf and raised road beside Dukes Wharf. A new flood wall and flood gate at Rowntree Park Caravan Site.

Completed Sep 2022

B10 - Clifton & Rawcliffe

20,600

140

Increased height of the existing barrier bank and extended at both northern and southern ends. A wider ‘footprint’ of the bank to reduce the angle of the slope and so reduce the risk of bank slippage in the future. A new pumping station within the barrier bank to control water levels in Blue Beck storage lagoon.

Nov 2023

B11 - Coppins Farm to Scarborough Bridge (Left Bank)

3,665

156

Raised height of the flood embankment in St Peters School fields. A new transition wall between the embankment and the development at the end of Almery Terrace. New floodgates and glass panels to increase the height of the flood defence along Almery Terrace. A new flood gate at the top of the Almery steps and piling within the Network Rail embankment.

Completed May 2022

 

B12 - Scarborough Bridge to Lendal Bridge (Left Bank)

2,950

57

Increased height of the existing flood wall from Scarborough bridge to Museum gardens. This includes new flood gates and glass panels along Earlsborough Terrace and Esplanade Court, a new flood gate near Scarborough Bridge and new demountable panels for the Marygate flood gate.

Revised date TBC

C1 - Bishopthorpe

3,390

170

A 180m long flood wall along Chantry Lane with a 6m deep steel barrier underground cut off. A flood gate across the bottom of Chantry Lane. A new manhole chamber with a penstock mechanism.

Completed Apr 2022

F8 /F10/F11-Foss Storage Area

17,526

490

Construction of a new embankment with outfall control structure upstream of York, designed to hold up to 1million m³ during times of extreme rainfall. Once downstream river levels recede, the stored water will be released at a controlled rate. The creation of two ponds connected to the River Foss, together with improvements to the river channel, will result in new wetland habitats to support wildlife.

Nov 2023

Foss Barrier

38,000

1600

Greatly increased pumping capacity with replacement of all 8 pumps, including new infrastructure and new power supplies. In addition to 2 independently sourced High Voltage electricity supplies the barrier has 5 new back-up generators to maintain operation of all eight pumps at maximum capacity in the event of catastrophic power failure. All vulnerable infrastructure raised to first floor height. A new taller barrier gate, lifting equipment and housing.

Completed Apr 2022

Stage

B9 – Germany Beck

City of York Council (CYC) led project with multiple benefits including increased flood protection to Fordlands Road and the A19 as well as reducing flood risk to local homes and businesses. Initial design has been completed and the planning submission has been made.

CYC

Design

F1 – Tower Street

We are investigating options on how to provide flood protection along Tower Street to prevent exceptionally high flood levels on the River Ouse bypassing the defences within St Georges Car Park and entering the Foss Basin which would pose increased flood risk in the lower Foss.  This scheme will initially involve raising of the wall between St George’s car park and the Foss Basin tying into Skeldergate Bridge.
