Field in Trust is a "national charity working to champion and support parks and green spaces by protecting them for people to enjoy in perpetuity" (Field in Trust, 2022). It surveys 493,400acres of green spaces across the UK and is based on the survey data to produce four maps reflecting the supply of parks and green spaces.

noteworthy thing is that while in Great Britain, 2.8 million people are "not living within a ten-minute walk of a green space" (Fields in Trust, 2020), in London, almost everyone can live within a ten-minute walk of green space, which means London's green space system is better than the average of Great Britain.

The GSI (Green Space Index) Score is Field in Trust's unique measure that shows "whether an area meets a minimum level of park and green space provision" (Field in Trust, 2022). In London, the total provision of green space and green space provision per person is high. The green space is evenly distributed, but outer London has more green space than inner London and has more per Thecapita.most

An analysis of the London green space landscape system shows an ample supply of green space in London. Across London, almost everyone lives within ten minutes of green space. The project aims to connect the green spaces of the surrounding neighbourhoods through Greenway, making it a coherent urban green space system. Greenway should activate East London like an urban artery, sending vitality to the city.

Hidden beneath the city streets of London lie 2,000 kilometres of brick tunnels, most of which were built in the mid-nineteenth century and are still in use

The Greenway footpath is a greenway landscape built on the sewers, connecting the discrete green spaces in East London, and is an important fast passage in the community. This passage has great potential to be transformed into an urban artery, linking the urban landscape to form a vibrant green space system.

London's Sewer System

There is a Northern Outfall Sewer in the East London area, which acts as a sewer in the north of the Thames, collecting sewage and sending it to Beckton Sewage Treatment. It has long been used as a footpath and was known as the 'Sewerbank'. In the 1990s, the embankment was renovated and renamed the Greenway. More landscaping has been done here as a legacy project following the 2012 Olympic and Paralympic Games.

Unlikely the majority of the main drainage system, the 4-miles-long Northern Outfall Sewer was built entirely above ground. Greenway is a long, flat turf and bike path laid over the sewer.

Greenway Analysis

From the floor plan, Greenway connects the community and green space of East London, as if it is a blood vessel connecting the city. However, in most sections, as the typical section shows, the Greenway road is 6-9 meters higher than the communities on both sides because of the Northern Outfall Sewer. It is like a dyke across the community.

High crime rates and water management are two of the most prominent issues on Greenway.

The inconspicuous height difference has caused many problems for the Greenway - the height difference makes the site difficult to access, and the passive use makes the Greenway have a high crime rate and gradually decline. The Northern Outfall Sewer was also overwhelmed by more than 150 years of use, and the city's water management system needed to be optimised.

At the same time, the Northern Outfall Sewer is built on the ground, which makes the Greenway higher than the surrounding community, like an island in the city. The closed borders and lack of exits further reduce Greenway's accessibility, making it an isolated linear green space in the community.

For now, the government has shortened the Greenway's opening hours, keeping it closed at night, and added CCTV along the Greenway to reduce crime and make it safer. Residents in the surrounding communities have spontaneously formed volunteer groups to log crimes online and warn those who want to go to Greenway to be safe. But so far, Greenway's crime rate has not improved significantly.

London Tideway Tunnels - Modernising London's Sewerage System

Issue 2 - Water Management

As a response, Tideway, the company constructing the super sewer which will be operated for Thames Water customers as part of its network, is busy building a 25km tunnel under the River Thames that will capture the millions of tonnes of untreated sewage that currently pollutes the river, before being taken away for treatment.London Tideway Tunnels make a considerable contribution to London's urban water management by modernising London's sewerage system.

The project aims to liberate Greenway from its identity as a closed, passive footpath, making it an urban artery for revitalizing the city.

There is a height difference of 4-9m between Greenway and its both sides, most of which are grass slopes or retaining walls, which seriously affect the accessibility of Greenway. In order to stimulate its vitality, this project will make reasonable use of the height difference and transform grass slopes and retaining walls into steps, ramps, and forest plank roads.

Greenway's turf covers its history, while few people know that Sir Bazalgette used it to save London two hundred years ago. This project will respond to the site's history, presenting it as a precious landmark of historical development, showcasing its past, present and future.

Greenway selects the surrounding green space according to local conditions and transforms it into sports fields, children's parks, wetland farms, etc., to create enough recreational environment for people, and respond to Greenway's history and urban water management. For the height difference on both sides, barrier-free ramps and steps have been designed in multiple places, and the boundaries have been opened up to make it a more popular venue.

The Greenway is a coherent whole, a single linear space where entrances and other nodes are repeated. Here, the typology method is used to divide the entire Greenway into six different parts—path, square, entrance, bridge, cliff and heritage. Six types of universal strategies and specific methods can be proposed for the six different spaces. This collection of design elements will be able to be applied to specific space design in a symbolic form.

This project collected a variety of outdoor landscape furniture and put them into Greenway. Landscape benches and outdoor loungers provide people with places to stop and rest, attract people to stop, and keep Greenway under constant surveillance to prevent crime. Street lamps increase lighting at night, thereby reducing crime rates. Because of the Northern Outfall Sewer below the Greenway, trees cannot be grown on the Greenway. Planting pools in landscape furniture provide places where shrubs, flowers and vegetables can be grown to optimize the landscape and enhance human participation. Planting galleries create vertical landscaping through vines while protecting sewers.

Streetscape Proposals

As a 4-mile linear venue, the landscape experience on Greenway is mostly streetscapes. One of the overall strategies for optimizing Greenway's landscape is to enhance the quality of Greenway's streetscape.

The combined use of landscape furniture can create rich streetscapes. Here, streetscape proposals are shown using nodes on Greenway as an example. The streetscape design is universal, and various design schemes will be integrated into Greenway to stimulate vitality.

# CSO Interception

RUNOFF INFILTRATION

With the development of industry, the popularization of sanitation facilities, and the city's expansion, the wastewater caused by London is increasing day by day, and the sewers constructed 150 years ago are difficult to meet the needs use. An intercepter sewer will be added along the Northern Outfall to maintain the water volume in this project. When the sewage volume is too large, some of the sewage can be intercepted to prevent the sewage from overflowing. A sewer network transports them to a sewage treatment plant, where they are purified and discharged into the Thames. At the same time, build rain gardens and wetlands in cities to increase urban water management capacity.

When urban growth makes the carrying capacity of the water system insufficient, it is possible to improve the carrying capacity of the urban sewage system and protect the Thames from pollution by updating the sewage pipe network and adding blue-green infrastructure.

# Dry Conditions

Urban Water Management

In order to prevent heavy rain from flushing sewage into the river, the project will build blue-green infrastructure and use integrated water management to reduce the amount of rainwater flowing into the Combined Sewer Overflow to prevent pollution from overflowing and improve the ability of the urban water management system to handle sewage and rainwater.

Combined Sewer Overflow systems are used in London. The sewer collects domestic sewage, industrial wastewater and surface runoff. Under normal circumstances, sewage will be sent to a sewage treatment plant, where it will be purified and discharged into rivers. But when the storm exceeds the sewer system's capacity, the untreated sewage will overflow the pipes and be discharged into the river.

This project builds blue-green infrastructure around the Northern Outfall sewer. As a linear green space, the permeable surface of Greenway is one of the important design elements. At the same time, as an urban expressway, the design of the pavement also needs to consider the specific use functions. Different permeable surface structures are listed below to suit different application

When designing, the local materials are preferred. At the same time, due to the load-bearing limitation of the sewer, the weight of the material itself should also be considered. After screening, the picture below shows 60 suitable landscape materials, including stone, wood, soil, metal, etc. Construction based on local materials can better protect the environment and respond to the history of the site.

Establishing wetland landscapes in low-lying areas is conducive to enriching urban ecosystems. An overhead walking path is established on the original landscape path, allowing people to walk on the wetland and close to the water landscape. Plants are planted on both sides of the Greenway, forming a forest belt and creating a natural environment.

The site is adjacent to Elizabeth Olympic Park, with a significant height difference on both sides, and was developed into an urban farm according to local conditions. Rainwater and greywater collected from surrounding roads and buildings are stored in storage tanks after primary purification by reed beds. The purified water can be used to irrigate farms and provide non-potable water resources to surrounding communities. The remainder will be discharged into the Northern Outfall sewer through the city's pipe network. The uptake of water by the wetlands relieves the processing pressure of the sewer.

Wetland Structure Design II

Wetland Structure Design

The landscape trail expands in width to form a settlement area. Planting plant strips in the middle of the pavement are conducive to collecting and managing rainwater. The treatment of the height difference forms terraces through the retaining wall, which enriches the surrounding green landscape.

The site is low-lying and adjacent to ample green space and was developed into a water storage wetland and a promenade according to local conditions. The wetlands are impervious to seepage to collect rainwater from nearby communities. The strong water storage capacity of the wetlands will significantly reduce the pressure of rainwater on the Northern Outfall sewer.

| 53 05 URBAN WATER MANAGEMENT

According to local conditions, the site is close to River Lee, with low terrain, and developed into an urban wetland. Wetlands can collect rainwater from surrounding roads and buildings, conduct preliminary rainwater purification, and replenish groundwater. The remainder will be discharged into the Northern Outfall sewer through the city's pipe network. The uptake of water by the wetlands relieves the processing pressure of the sewer.

Pavement Contructions

Only a single road is reserved for the landscaped walking path, and the green space is maximized. At the same time, a space near the water is added, and wetland plants are used to bring about a transitional height difference.

# Cobble Strip# Paving Layouts

Lay a cobble made of Gowanus cobbles strip where the paving and planting areas meet. It allows water to flow and infiltrate along the cobble strip, increasing the water storage capacity of the green space. Such strips are also established on the pavement to organize the rainwater runoff, while demonstrating this unique construction technique to the public.

Walkable Communities

The updated design of Greenway respects the original site, and optimizes Greenway on the basis of retaining the original functions. Site I will transform the green space near the Olympic Sports Park into a green space for sports and recreation. Site II retains the original decaying children's park, redesigns it, and re-energizes it. Site III is adjacent to a canal and has a large area of unused green space, so a blue-green infrastructure has been established here. Site IV is located at an intersection with complex traffic and chaotic traffic, so recreational installations and wall paintings are installed in the sidewalk area to optimize the walking experience.

Greenway renovation design aims to bring it back to life with minimal changes, reduce crime on it, energize the community and support the urban water management system.

Greenway is a liner walkable community. In this project, in addition to the walking path as the central axis, the communities on both sides of the walking path are also designed.

Rain gardens are arranged in the park, and at the same time assume the function of urban blue-green infrastructure.The original dense forest is preserved on the south side of the site, and aerial plank roads are set up in it based on local materials to create a jungle adventure experience.

Site I is located in the southern part of the Olympic Sports Park, and the original site was an abandoned wasteland. Here it is transformed into a green space for sports and leisure.

Site II retains the original decaying children's park, redesigns it, and re-energizes it. The original children's park facilities are simple, and the audience is narrow. Recreational facilities will be added here to make it accessible to children of a wider age.

With the help of the grass slope on the site, a wave-shaped stacked platform is set up, and the platform is connected by a climbing wall. At the same time, large-scale slides are set up with the help of the height difference of Greenway to attract adults and children to enter the venue through the slides. A skate park is set up in the open space in the west of the venue to provide a variety of play methods. Instead of a single lawn, the ground is planted with native wildflowers to create flower fields.

Site III is adjacent to a canal and has a large area of unused green space, where a blue-green infrastructure is set up to complement urban water management according to local conditions.

The wild green space in the southern part of Greenway is adjacent to railways and canals, and can collect urban rainwater to create urban wetlands. Vegetables can be grown on the wetland through the three-dimensional truss device, becoming an urban farm.

Hydroponic Cultivation on Wetlands

Prompt: Beneath the Greenway are wetlands that serve as urban blue-green infrastructure. There is a three-dimensional planting device on the wetland, and a foam hydroponic planting box is suspended. In the background are the river and the industrial remains of the city.

The space under the viaduct is noisy and cold. Here, warm-colored wall paintings are used to decorate the space under the bridge, so that people can also feel the vitality brought by Greenway when crossing the viaduct.

Site IV is located at a complex intersection where traffic is chaotic and people's cycling and walking experience is interrupted here. In order to optimize the visitor experience, a variety of landscape furniture is installed along the walking path connecting Greenway, and the space at the corner of the intersection is widened to form a small square or add recreational facilities.
