Water case studies published on LI website

The Landscape Institute has added 13 case studies to the website, all dealing with the vital topic of water. The case studies were selected from more that one hundred water-related case studies submitted last year as part of a competition for their inclusion on the LI website.

You can find all the LI case studies on our website.

The case studies are:

All London Green Grid – London Downlands Planning Guidance
Lead landscape architect: 
Kinnear Landscape Architects 

Working closely with Design for London (UK) and the London Boroughs of Bromley, Sutton and Croydon, Kinnear Landscape Architects (KLA) acted as design advisors to Area 7: London’s Downlands section of the All London Green Grid (ALGG), defining a strategic vision for the London region, where one of the key issues for the city is the health of three large rivers that run through the area.

Ribblesdale Road, Nottingham – Retrofit Rain Gardens
Lead landscape architect: Groundwork Greater Nottingham

The scheme was developed with the vision to encourage and support change locally in dealing with issues around the water environment. The pilot project aimed at achieving a deliverable project that could be assessed over time and draw together statutory authorities to learn about Sustainable Drainage Systems (SuDS) and evoke change.

Millennium Town Park, St. Helier
Lead landscape architect: Burns + Nice

The park was seen as an opportunity to bring immediate benefits to an area deprived of open space and demographically one of the poorest parts of Jersey. The transformation of the contaminated site into a park with trees and lawns could create a place for recreation and enjoyment and act as a catalyst for the regeneration of the surrounding area. A proposed scheme emerged after a robust site appraisal, establishing the relationship between the future park and the wider urban context.

Stebonheath Primary School
Lead landscape architect: Arup

Stebonheath School is situated within a residential area of Llanelli where a number of streets have experienced surface water flooding. Modelling estimated that the school was contributing high flow rates to the nearby combined sewer at a rate of around 61l/s during a 1 in 5 year storm event. The school had very little green space, but did have a car park to the front and a large playground to the rear. The school grounds presented an opportunity to reduce and attenuate surface water runoff from the site whilst providing a valuable educational resource for the community.

Medmerry Managed Realignment Scheme
Lead landscape architect: 
Jacobs

This scheme is the largest managed realignment of the open coast in Europe, and the first in the UK on the stretch of coast most threatened by coastal flooding. It has been recognised locally, nationally and internationally as an exemplar project. The scheme has significantly reduced the risk of coastal flooding to the residents of Selsey and the surrounding communities, whilst also providing more than 180 hectares of important new intertidal habitat, providing compensation for losses in the Solent as a result of rising sea levels.

Riverside Court
Lead landscape architect: Robert Bray Associates

The site was originally an electricity sub-station located in the middle of Stamford in a prime riverside position. The high-density development of 106 units per hectare required every landscape surface to be considered as a SuDS collector and opportunity for cleaning and storing water.

Nottingham Flood Alleviation Scheme
Lead landscape architect: 
Ryder Landscape Consultants

This is a large-scale scheme running for 27km along the River Trent as it meanders through Nottingham. The scheme runs through countryside, suburbia, parks, industrial areas and SSSI’s each raising their own challenges and each requiring a careful and considered set of proposals suitable for the individual location.

Bewdley Severnside South Flood Alleviation Scheme
Lead landscape architect: Environment Agency National Environmental Assessment Service

Bewdley is a Worcestershire market town, strategically placed as a crossing point on the River Severn. The town has historically suffered from fluvial flooding and initial consultations during the 1990s for a flood defence scheme were discontinued initially on the grounds of a significant negative impact. Flood events in 1999 and extensive flooding of 175 properties in the winter of 2000 acted to focus minds. With the political will to accelerate a scheme, design work for flood defences began by the summer of 2000. Public and stakeholder engagement by the Environment Agency with residents, businesses, local authority and key stakeholders led to the introduction of the design of a new form of demountable flood defence.

Sustainable Drainage: Cambridge Design and Adoption Guide
Lead landscape architect: 
The Landscape Partnership 

When Cambridge City Council took the decision to adopt SuDS features within public open space, it commissioned a Design and Adoption Guide for SuDS  to support the resolution and to inform the design of SuDS and minimise the risk and liability to the City Council. The guide was the first of its kind in the country. It is written in an accessible and non-technical manner, so as to be suitable for a variety of users including developers, landscape architects, engineers, and planners.

Sustainable Drainage System, Rednock School, Dursley
Lead landscape architect: 
Illman Young Landscape Design 

The aim of the SuDS system was to maximise the existing potential of the site, to attenuate and clean water, while providing a valuable amenity. The SuDS were designed to provide many opportunities for the pupils to learn about the natural water cycle and habitats and for the staff to use it as a resource within the curriculum, by creating and integrating well designed landscaped features and promoting a greater diversity of flora and fauna.

Alcester Primary Care Centre, Alcester, Warwickshire
Lead landscape architect: 
DSA Environment & Design

It became clear early on that an innovative approach to drainage should be used to encourage biodiversity and create an environment for patients to explore. The concept of a SuDS ‘treatment train’ to deal with storm water was employed. Water is fed from the building roof and hard surfaces via permeable paving into a series of rain gardens containing chiefly native species, ultimately to soakaway. These areas are laid out in a bold sinuous form and planted with native wetland edge species including sedges and grasses.

Jubilee River
Lead landscape arcitect: 
Environment Agency National Environmental Assessment Service

The Jubilee River is a one of the most significant fluvial flood risk management schemes, in terms of scale and investment, in the UK. It incorporates a wide range of aspects including significant areas of wetland and marginal habitats, a national cycle route, bridleways, and a significant length of the Thames long distance footpath. Much of the planning and design work for the project was highly innovative as for the first time the scheme took major water management infrastructure development into the realms of multiple use green infrastructure.

Thames Estuary 2100, riverside appraisal and options study
Lead landscape architect: Arup Landscape (Tom Armour, Mark Job) Environment Agency (Richard Copas)

The Thames Estuary 2100, Riverside Appraisal and Options Study relates to the Thames Estuary 2100 (TE2100) Environment Agency project to develop a tidal flood risk management strategy for the River Thames. It sets out the initial riverside planning appraisal for all 23 Policy Units along the tidal extent of the River Thames.
