York Flood Alleviation Scheme (FAS) The Clementhorpe Community Information Page

Closes 31 Dec 2021

Opened 9 Jul 2018

Overview

The purpose of this page is to provide information on how the Environment Agency aims to reduce the risk of flooding for homes and businesses in the Clementhorpe area. We have been developing plans and actively engaging with the community 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.

The York 5 Year Plan identified 10 separate areas at risk of flooding.  This includes the community of Clementhorpe, 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 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

The Problem

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.   

The Solution

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

  • Raising existing walls along Postern Close at the corners by up to 25cm and the construction of a new 1.5m high flood defence wall between the Postern Close buildings;
  • A new demountable defence/floodgate 2m high across the end of Clementhorpe;
  • A new 1.85m flood wall in front of Waterfront House with glass panel inserts in front of Juliette doors and structural glass replacing existing window panels. An extra step will be added to the existing steps between Waterfront House and Duke's Wharf;
  • A new flood wall in place of the existing wall on the access road into Duke's Wharf;
  • Raising of the private road level at Duke’s Wharf;
  • A new flood wall in Duke’s Wharf up to 70cm high to tie in to the newly raised road level and the newly constructed flood wall at Roomzzz;
  • Increase of height to existing flood wall and installation of new embankments and low level walls in the Caravan Park;
  • Installation of a new embankment with footpath at the northern entrance to Rowntree Park. The height is likely to be 30cm and tied into a newly raised curb along the existing park railings.

Timescales and Next Steps

Structural Site investigations

We have been carrying out further site investigations. These are required to ensure that we construct a sound line of protection without compromising the structure of existing buildings in the area.

The final phase of site investigations are planned from the 4 - 14 March. These include works within Postern Close Gardens, along Terry Avenue and Clementhorpe Road and within the Caravan Park. A road closure has been granted for the duration of these works, as detailed in the notice below.

The results will be used to complete the detailed design of our potential scheme.

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 material displayed at the event can be found in the 'Related' section at the bottom of this page. 

We plan to submit our proposals for planning approval by the end of the month.

The Problem

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.

The Solution

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).

What is PFR?

Property Flood Resilience involves modifying existing properties to reduce the chance of water entering the building. It is also important to reduce the impact of flooding should water get inside. The aim is to ensure that damage is minimised and you can get back in to your home or business as quickly as possible. PFR looks at individual properties to identify the best solution for reducing the chance and impact of flooding.

If you want more information on Property Flood Resilience, you can read about it on the National Flood Forum’s website. This is a great one stop shop to learn about PFR from an independent source.

Am I eligible for funding to install PFR?

There are two ways that we determine PFR eligibility.

  1. threshold surveys to identify properties at risk of flooding. This involves measuring the lowest point at which water may enter a property, and comparing this against our flood models;
  2. asking residents whether they have experienced flooding in the past to contact us with evidence.

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. The time frame is now as follows:

    • June – supplier appointed;
    • July – product selection commences (working with individual residents);
    • August onwards – products ordered and installation begins.

 

We will be consulting with residents to discuss personal requirements during July and August. We are aware that this is peak holiday time for many people, but unfortunately, this is when your input will be required.  We will look at providing various opportunities to have these necessary discussions.

This page provides information, documents and maps relating to the proposals for reducing flood risk in the Clementhorpe Community.

We will update this page with information throughout the year. If you would like to provide any feedback, or have any questions, please contact us at yorkfloodplan@environment-agency.gov.uk.

This information is not part of a consultation, but we would welcome feedback, and questions. Please use the email above.
