Outstrays to Skeffling Managed Realignment Scheme

Closes 31 Dec 2020

Opened 20 Dec 2018

Overview

This page provides a summary of proposals for the Outstrays to Skeffling Managed Realignment Scheme.

What’s proposed:

The Outstrays to Skeffling Managed Realignment Scheme is a joint initiative proposed by the Environment Agency (EA) and Associated British Ports (ABP) to create over 400 hectares (988 acres) of new mudflats and saltmarsh on the north bank of the Humber estuary, near Skeffling. ‘Managed realignment’ means altering the location of existing flood defences.  In the case of Skeffling, this involves moving the embankment further inland to establish a new line of defence and then breaching the old embankment so that sea water can enter through the breach to facilitate the creation of intertidal habitat.

   Plan of the Outstrays to Skeffling Managed Realignment Scheme

The site between Outstrays and Skeffling was chosen for a managed realignment scheme because the land levels are suitable.  It is divided into three distinct areas, shown on the map above:

  • the western side (from Hawkins Point to Winestead pumping station, labelled as West 1);
  • a middle area of wet grassland habitat (above high tide levels and included in the scheme to increase the range of habitats on the site and provide the right conditions for rare species, labelled as West 2);
  • and the eastern side, extending up to Skeffling pumping station (labelled as East 1, 2 and 3).

The Humber Estuary is recognised as one of the most important estuaries for wildlife in Europe and has been designated as a site of nature conservation under both national and international legislation. Under the Habitats Directive (2010), the Environment Agency and Associated British Ports are legally obliged to replace any habitat lost as a result of our interventions in the estuary, such as the expansion of port facilities, and by a process called ‘coastal squeeze’.  This occurs where the high water mark is fixed by a flood defence structure such as a wall and the low water mark moves landwards as the sea level rises, leading to a loss of intertidal habitat. The figure below illustrates this process.

Creating new areas of habitat to compensate for those lost will ensure that the unique environment of the Humber estuary is preserved and protected for future populations of wildlife and people.  The need for this is highlighted and further explained in the Humber Flood Risk Management Strategy

Habitat creation

The scheme will create new areas of saltmarsh and mudflat. These will provide habitats and food for a variety of bird species found within the estuary such as golden plovers, turnstones, ringed plover, lapwing, teal, avocets and curlew.  Some of these species use the estuary as a resting point whilst migrating and others stop and overwinter on the Humber. They come from northern locations such as Scandinavia, Iceland, Greenland and the Arctic.

Curlew

Other types of habitat (wet grassland and high tide roosting sites) will also be created on the site to provide a mosaic of different conditions supporting populations of redshank, knot and dunlin. Once the site is built, we hope that the area will be managed as a Local Nature Reserve.

Wider scheme benefits

In addition to creating new habitats for wildlife, the scheme offers other benefits.  These include:

  • improved flood protection for residents in the Welwick, Weeton and Skeffling areas;
  • better access and facilities for recreational visits to the new nature reserve;
  • opportunities to improve drainage on adjacent agricultural land;
  • opportunities for industrial growth and development in the ports around the Humber estuary, creating jobs and economic prosperity in East Yorkshire;
  • enabling improvements in flood protection to be built in Hull and other urban centres, benefiting 400,000 residents living in the Humber flood plain.

The design process

The design for the scheme has been developed over several years. In order to inform this process, we have carried out a range of investigations including: 

  • Tidal modelling – studying how the water will move onto and around the site once the scheme is built; 
  • Archaeology – investigating and recording any features of historical interest on the site;
  • Environmental investigations – to understand what animals and plants are found in the area and what measures we need to put in place to protect them or relocate them whilst the scheme is being built;
  • Ground conditions – we have undertaken tests within the site area to understand what we are building on and to establish whether we can use material found within the site rather than importing materials from outside.

Involving local communities

Whilst developing the designs for the scheme, we have engaged with many different people and organisations in the area to provide them with up-to-date information and give everyone an opportunity to contribute their views.

Over the past few years we have listened to and considered ideas and suggestions from the public and local organisations on ways to improve the design of the scheme. As well as producing a quarterly newsletter to report on progress with the scheme, we have held regular events in the area, including Q&A style ‘surgeries’ and public ‘drop-ins’.  These have given us the opportunity to provide updates on our plans, listen to the views of residents and answer questions. We have subsequently taken on board feedback from these public sessions and used this information to review and reshape our plans.

Dispalys in Welwick Village Hall in 2017

In the summer of 2017, we organised workshops to give residents and local groups a chance to comment on our early designs and suggest ways in which the scheme could be enhanced.

A particular concern highlighted by residents was the location of public access routes in the new scheme. In the original design for the eastern side of the scheme, the path for walkers and horse riders ran along the bottom of the (inner) ‘toe’ side of the new embankment. This route was chosen to minimise disturbance to bird populations but would have resulted in a loss of views across the estuary for human visitors. To resolve this problem, we sought advice from a wide range of experts and conservation bodies.  We then redesigned access routes to balance the demands for conservation and public access.  The result was that over 70% of the new route now follows the top of the embankment.  The path only goes down onto the ‘toe’ side where it is near to sensitive areas for wildlife (shown on the map below). It will be designated as a bridleway and surfaced in key places to ensure disabled visitors can access the site. It will also be fenced so that dog owners can let their dogs off the lead without disturbing birds.

What happens next?

We intend to submit two separate planning applications for the scheme in early 2019, one for the west side and one for the east. 

Prior to obtaining planning permission, we have completed an Environmental Impact Assessment (EIA) and presented the results from this in an Environmental Statement (ES). This describes all the environmental impacts likely to result from the scheme during construction and after. It also includes mitigation measures, setting out how we will avoid or minimise some of the possible impacts resulting from construction of the scheme.  The Environmental Statement will be submitted along with our planning applications to East Riding of Yorkshire Council in early 2019.  Once validated, you will then be able to view all these documents via the council’s planning portal.

A Non-Technical Summary of the Environmental Statement can be accessed here

We have conducted several other surveys to support the Environmental Statement, including a Water Framework Directive Assessment (WFD) and a Habitats Regulation Assessment (HRA).  These will be included with the planning applications for consideration by East Riding of Yorkshire Council. You will be able to view all these documents once they have been uploaded to ERYC's planning portal:

Before the planning applications are submitted, we intend to hold a series of public events in the area in early 2019. The purpose of these is to offer local residents and other interested organisations the chance to see our designs for the project and to provide opportunities for people to ask questions or comment on them.  Dates for these events  are as follows:

Tuesday 5th February            Skeffling Village Hall, 3pm to 7pm

Wednesday 6th Feburary       Patrington Village Hall, 3pm to 7pm

Thursday 7th February           Welwick Village Hall, 3pm to 7pm

We will also continue to speak with local residents, interested organisations and parish councils as the planning application progresses.

When will work start?

Building the scheme is likely to be a long and complicated process, lasting two to three years. We expect the first phase of construction will start in the summer of 2019.  It will then pause over the winter and resume in the spring of 2020.  We envisage the project will be completed by the autumn of 2022.

We want to ensure that any impacts on local residents from the construction phase are kept to a minimum.  So we will work closely with East Riding of Yorkshire Council to draw up a traffic plan for moving vehicles, materials and people to and from the site. We will also make sure that communication channels remain open once work starts on site and that residents and local orgnisations can pass on any issues or concerns arising during the construction phase.
