Working hours

The Phase 1 working hours, approved through planning permission, are 8am to 6pm Monday to Friday and 9am – 2pm on Saturdays. The Environment Agency and its construction partner VolkerStevin do not expect to work on weekends or public holidays.  Note: Utility and service providers may agree different working times with local councils.

Minimising construction noise and dust

Unfortunately, some noise and dust will be created during construction. VolkerStevin will monitor and manage noise, vibration, and dust levels, and will endeavour to minimise the impact on homes, businesses, public areas, and the surrounding natural environment where possible.

To manage any construction-related road debris, cleaning of the carriageway will be undertaken by a road sweeper or similar, as appropriate.

Construction traffic

The work areas will be compact to minimise disruption. Designated routes will be used to bring materials and machinery to site compounds, from where they will be distributed to the various work zones.

Diversions and closures will be required in some areas and Traffic Management Plans will be agreed with Lancashire County Council’s Highways Department, who will ensure any temporary road or lane closures are managed appropriately to minimise traffic disruption.

Broadgate Gardens

Broadgate Gardens has been restored with a mix of fruit trees, ornamental shrubs, and amenity grassland. Additional seating areas have been provided and the Environment Agency has restored the riverside viewing platform.

Newly opened Broadgate Gardens

Ribble Sidings

In Lower Penwortham, the Environment Agency is working with South Ribble Borough Council to create an insect and wildlife-friendly wetland habitat, the design includes:

• Woodland area with 170 native trees planted.
• Orchard with five varieties of fruit trees.
• Species rich grassland.
• Native wildflowers and bulbs.
• Two pond scrapes.
• Network of paths through and around the site.

An area of amenity grassland and the existing children’s playground has been retained for recreation.

Victoria Road viewing platform

The Victoria Road viewing platform will be restored following the works with improved planting, surfacing and seating facilities.

Inclusive design

The design team has worked carefully to consider everyone’s needs.

• Providing footpaths to allow pedestrians better access to public green spaces.
• Providing seating, including benches with backrests and armrests in key locations.
• Avoiding stepped access, where possible, and creating ramped access.
• Avoiding awkward changes in level that may pose trip hazards and providing visual contrast between changes in levels.
• Planting new trees, grasses, wildflowers, perennials, and shrubs to promote mental health and wellbeing.

The Environment Agency has worked with local schools to deliver educational sessions, this includes teaching students about the dangers of flooding, and the impact of climate change.

The Scheme has also delivered improved surface water drainage in playgrounds for three local primary schools. Elements of Sustainable Drainage Systems (SuDS) have been installed, which include permeable surfacing, rainwater planters, water butts, and trees. SuDS is a nature-based method that helps reduce surface water and improve water quality, by:

• Capturing rainwater runoff to reduce flood risk
• Storing runoff and releasing it slowly
• Slowing the flow of rain to drains
• Filtering out pollutants

Projects have been completed at:

• Frenchwood Community Primary, Preston
• St Mary Magdalen’s Catholic Primary, Lower Penwortham
• St Leonard’s Primary C.E., Walton-le-Dale

Trees

Surveys are conducted before any tree removal takes place, this is carried out in consultation with relevant partners. Trees are incorporated into the Scheme’s design to support natural habitats and for other purposes, where possible.

The Scheme is committed to planting at least 12 trees for every tree removed due to construction, and it’s worked closely with partners to identify planting locations. This includes planting over 8,500 trees and 2,550 hedgerow species along the river at Fishwick Bottoms in Preston. The Scheme has also supported South Ribble Borough Council’s “Plant 110,000 Trees” programme, with extensive planting at Golden Way in Lower Penwortham.

Proposals for replacement and compensatory planting, as well as landscaping and biodiversity requirements, are detailed within the environmental masterplans as part of the planning application submissions.

About the Victoria Road lime trees

To enable construction works along Victoria Road, some of the trees on the river side of the existing wall will need to be removed. Removing trees is not something the Environment Agency undertakes lightly. Extensive investigations, including tree root radar surveys and engineering assessments, were carried out to try and identify alternative designs that could preserve them. Unfortunately, due to the density and spread of the root systems, and the proximity of the trees to the required working area, it is not feasible to retain them and construct the flood defences.

The proposed design includes the removal of 18 lime trees, but three others at the viewing platform will not interfere with works and won’t be removed. The Environment Agency is also exploring further ways to mitigate the tree loss. 180 cuttings have been taken from the trees, which are being propagated and will be planted elsewhere in the community. 14,000 trees have been planted as part of the Scheme on the opposite bank in Fishwick Bottoms

More details on the lime trees can be found here.

Ecology

A range of ecological surveys have been undertaken to inform and support the Scheme. The Scheme encompasses habitats typical of the urban setting along the River Ribble and River Darwen, i.e. grasslands, tree lines, roads, bridges, and pedestrianised areas. The surveys pay particular attention to otters living along the River Ribble and to local bat activity.

Working in the river is avoided wherever possible but when it is necessary, it is restricted to between mid-June and January. This avoids impacting coarse fish, smelt (small fish), and eels present in the River Ribble.

The Scheme has invested in habitat creation, this has mostly taken place at Fishwick Bottoms in Preston with the planting of native trees and hedgerows, and at Ribble Sidings in Lower Penwortham with the construction of an insect-friendly wetland.

Historical structures and features

Some of the new flood defences will be constructed close to historic structures—such as Penwortham Old Bridge—or close to conservation areas. Extra care will be taken when working in these sensitive locations.

Any small heritage features, such as mile markers, will be carefully removed during construction and reinstated in their original positions once the flood defences are complete.

Why create the Flood Scheme?

There is a long history of flooding in Preston and South Ribble, with records dating back to the 1700s. Several significant flood events have occurred since 1936, including Storm Eva in 2015.

The existing flood defences were constructed between the 1920s and the early 2000s. Many of these structures are now approaching the end of their design life and require repair, replacement, or extension. In other areas, entirely new defences will be built.  The Scheme will also take into consideration climate change and environmental enhancements.

How many homes and businesses will be protected?

The proposed Scheme will better protect around 5,000 residential properties and businesses from direct flooding from the River Ribble and the River Darwen. There is also a focus on growth and regeneration in the areas where the Scheme is being constructed.
