The River Alt Restoration Project at Stonebridge started in 2013 with an initial goal to remove culverts in order to create re-naturalised watercourses and maintain watercourses easier. It also involved the removal of rubbish and other obstructions to reduce the risk of flooding in the wider catchment (Reference 2). The project then evolved with a bigger goal to divert River Alt into a new 900-meter long linear park named Alt Meadows. Relevant engineering works were employed in the area. In addition, accessible paths and meadow, wetland and woodland habitats were created. The park was also linked into surrounding areas (like housing, shops, schools, etc.). The project benefits include the expected increase in wildlife biodiversity and improved water quality and flood protection (Reference 1, 3). The project was led The Cass Foundation, in partnership with the Community Forest Trust, with funding from DEFRA’s Catchment Restoration Fund (via Environmental Agency) and Liverpool City Council. The Foundation remains responsible for maintaining Alt Meadows on behalf of the city council (Reference 3).

Overview

Nature-based solution

  • Parks and urban forests
  • Large urban parks or forests
  • Green corridors and green belts
  • Blue infrastructure
  • Rivers/streams/canals/estuaries
  • Green areas for water management
  • Sustainable urban drainage systems

Key challenges

  • Climate action for adaptation, resilience and mitigation (SDG 13)
  • Climate change adaptation
  • Water management (SDG 6)
  • Flood protection
  • Stormwater and rainfall management and storage
  • Improvements to water quality
  • Green space, habitats and biodiversity (SDG 15)
  • Habitat and biodiversity restoration
  • Habitat and biodiversity conservation
  • Green space creation and/or management

Focus

Creation of new green areas, Ecological restoration of degraded ecosystems, Protection of natural ecosystems, Transformation of previously derelict areas, Management and improved protection of rivers and other blue areas

Project objectives

The project aimed to create a new public open green space and opening up the River Alt. Issues that project aimed to address are (reference 1):  Poor river morphology;  High flood risk within extensive built-up areas and agricultural land;  Fly-tipping and debris removal causes an ongoing maintenance issue and a risk to the blockage and failure of culverted river sections;  Presence of invasive species including Japanese Knotweed and Himalayan Balsam;  A closed, man-made, culvert river section creating a poor environment for biodiversity;  Isolated green spaces and poor habitat connectivity;  The need for meaningful engagement with the community;  Derelict, underused, neglected and brownfield land blighting a deprived area of the city.

Implementation activities

1- Channel excavation was done to help minimize erosion and enhance habitat diversity, significant increase in flood storage capacity within the river corridor and reduction of flood risk elsewhere in the catchment. (Reference 1) 2 . A mosaic of habitats was created including extensive planting of the riparian and marginal wetland (Reference 1) 3. Invasive weed species were managed (Reference 1) 4. Access for easy maintenance of the watercourse, including vegetation was provided (Reference 1) 5. Engagement activities like public consultation, 'walk and talk' sessions and conservation volunteering and training among many others were conducted (Reference 1)

Details on the roles of the organisations involved in the project

The Cass Foundation led and managed the project. It remains responsible for maintaining the built riverside park, Alt Meadows (Reference 1, 3) There is a partnership with Community Forest Trust, with funding from DEFRA's Catchment Restoration Fund (via the Environment Agency) and Liverpool City Council. Staff and students from the University of Liverpool, Professor Janet Hooke, are involved in monitoring and studying the success of the project. Local people/ community are involved in volunteering activities. Lancashire Wildlife Trust has the role of a maintenance contractor. (Reference 3)
