Introduction What is Green Infrastructure? Green infrastructure (GI) is a network of green spaces (as well as features such as street trees and green roofs) that is planned, designed and managed to deliver a range of benefits [1] including: Benefits for People – Healthy living (physical & mental) – Encouraging walking and cycling – Improving air and water quality – Reducing noise pollution – Environmental education Benefits for the Environment – Mitigating flooding – Cooling the urban environment – Enhancing biodiversity and ecological resilience – Climate change mitigation What Is a Green Audit? A green audit accurately maps and analyses existing GI features within a defined study area. The Community Brain C.I.C. wanted to undertake this audit as part of a two year community-led regeneration project in Tolworth, Kingston upon Thames, called SHEDx - www.SHEDx.org. SHEDx, a partnership with Kingston Council and supported by the Mayor of London’s Good Growth Fund, is also tasked with the introduction of new GI features to Tolworth. Therefore, in addition to looking at existing GI, this audit also identifies 25 opportunity projects for new GI features. A summary of these projects, ordered by type, can be found in the Green Infrastructure Opportunity Areas chapter on pg 46.
Methodology This audit draws on data from a variety of sources, including but not limited to: – Open data from MAGIC (Defra) – Open data from Greenspace Info for Greater London (GiGL) – Open data from the Greater London Authority (GLA) – Open data from the Environment Agency – Open data from the All London Green Grid (©GROSS.MAX) – Open data from the Tolworth Area Plan (©WeMadeThat) – SHEDx data provided by Kingston Council – SHEDx aerial drone footage of Tolworth – SHEDx data from an online green audit survey – SHEDx documented feedback at public events – SHEDx street surveys undertaken by BA Geography students from Kingston University – SHEDx Vegetation surveys undertaken by MA Architecture students from Kingston University Scope and Limitation The scope of this Green Audit is limited to the SHEDx impact area, as identified opposite.

Why Does Tolworth Need Improved Green Infrastructure? Kingston has one of the top ten fastest growing populations in the country with an expected rise of 16.2% in 10 years (ONS, 2016). As an area of the borough which is already undergoing increased urbanisation and population growth, better quality green infrastructure needs to be expanded. New green infrastructure could also help mitigate against climate change impacts such as flooding and urban overheating.
Tolworth suffers from some of the highest air pollution levels in Kingston [2]. Although the most effective method of addressing air pollution is at the source, GI has the ability to disperse pollutants and thereby ‘reduce public exposure’ [3]. A tool called GI4RAQ is currently being developed by Dr James Levine at Birmingham University to aid placing GI.
New green infrastructure in Tolworth provides an opportunity to bring together existing and new communities through planting events and a longer term sense of ownership through planting adoption. Street tree schemes in particular are a fantastic way to unite neighbours with a shared project and aims.
In addition to poor air quality and noise pollution, Tolworth also suffers from a existing lack of quality public space As Transport for London suggests, “places to stop and rest benefit everyone, including local businesses, as people will be more willing to visit, spend time in, or meet other people on our streets” [4].
Attractive public spaces create more interesting journeys for pedestrians and cyclists and could contribute to an increased sense of pride for the residents of Tolworth. More pleasant public spaces are also beneficial to businesses, especially on the Broadway, where people might spend more time.

New GI in Tolworth could help support biodiversity through the creation of new habitats to form a suburban wildlife corridor. Projects which bolster biodiversity on existing green assets should be supported and the public should also be supported in bringing wildlife into their gardens where possible.
Improved green infrastructure in Tolworth could include the creation of new local amenity green spaces, such as community orchards. Such spaces further promote the Transport for London principles, providing new amenity for people to relax in their leisure time, meet neighbours and go for a picnic.
New green infrastructure which supports food growing in Tolworth is an aspiration of the Greater London Authority to “promote productive landscapes including sustainable food production. New forms of urban agriculture, including public urban farms, could promote healthy living.” [5].
In Tolworth the Hogsmill River, Bonesgate and Surbiton Streams all carry a risk of river flooding (fluvial). Flooding events due to storm water run-off (pluvial) also increase pressure on our aging drainage system. Sustainable Drainage Systems (SuDS), including rain gardens, new trees, green roofs, and general ‘de-paving’ could help mitigate flooding risk.
The planting of trees and shrubs can lower surface and air temperatures in urban areas by providing shade and cooling through evapotranspiration. Green roofs are particularly good at absorbing heat.
New green infrastructure could help buffer noise pollution, particularly in areas directly adjacent to the A3. Trees and shrubs with dense branches at ground level provide excellent noise reduction.

Who is this Document for and How Should it Be Used? This document is a guide for anyone who would like to know more about green infrastructure in Tolworth and why it is important. It ends with a summary of opportunity projects for local partners to explore, which starts on page 48. Local partners include, but are not limited to, the local authority, conservation organisations, environmental groups, educational facilities, businesses and community groups such as friends of parks and neighbourhood associations. Local residents are also encouraged to improve biodiversity in their own gardens. The green infrastructure opportunity areas are presented as a hierarchy of interventions ranging from large scale habitat management projects through to small scale opportunities, such as potential locations for new street trees. The Tolworth Green Audit has been developed in partnership with Kingston Environment Centre (KEC), who work with local individuals and environmental organisations to secure a sustainable future for Kingston upon Thames.

Context A Brief Introduction to Tolworth Tolworth, in southwest London, is part of the Royal Borough of Kingston upon Thames. Most famous perhaps for its tower, Tolworth currently suffers from some of the highest air pollution levels in Kingston. In geographical terms, Tolworth is loosely divided into four quarters by two major roads. The A3 motorway, running south west to north east, separates green spaces in the south from more populated areas in the north. The A240, running north west to south east, creates further severance along the high street Tolworth Broadway. Tolworth now faces a period of significant regeneration. The future prospect of Crossrail 2 combined with major new developments such as the Meyer site (950 new homes), the conversion of Tolworth Tower into residential and the Lidl HQ are bringing focus on this part of the Borough. In 2016, The Greater London Authority (GLA), Transport for London (TfL) and Kingston Council jointly commissioned ‘We Made That’ to prepare an area plan for Tolworth. In addition to setting out a vision and strategy for future development in the area, The Tolworth Area Plan (TAP) also makes key recommendations for the introduction of new GI in Tolworth. A summary of these recommendations can be found on page 32.
Social Context Kingston has one of the top ten fastest growing populations in the country with an expected rise of 16.2% in 10 years (ONS, 2016). The largest two wards in the study area, Tolworth and Hook Rise and Alexandra wards, represent about 1/9 of Kingston’s total population, with 20,370 residents (ONS, 2016). Tolworth benefits from a relatively diverse population, when compared to Kingston as a whole, with higher percentages of residents from ‘other Asian’, ‘other White’ and Indian backgrounds (2011 Census). 8% of households in Tolworth and Hook Rise and Alexandra wards do not have English as their main language (2011 Census). This diversity is reflected in a vibrant and successful high street with shops on the Broadway catering to a rich variety of communities from around the world. Educational attainment in Tolworth is lower than the borough average, with 15.8% of the population in Alexandra Ward and 18.4% in Tolworth and Hook Rise with no qualifications compared to 13.4% for the whole of Kingston (2011 Census).

Transport and Air Quality Tolworth is a key transport hub for Kingston, with the A3 motorway and A240 acting as major arteries into the town centre. High levels of traffic contribute to some of the worst air pollution in the borough, particularly at Tolworth and Hook Roundabouts. As shown in the diagram opposite, which utilises data from the London Atmospheric Emissions Inventory (LAEI), areas of heavy congestion have previously exceeded the UK’s annual mean target of 40 micrograms (µg) of nitrogen dioxide (NO2) per cubic metre (m3). Although the planting of ‘air quality gardens’ can help to mitigate some of these harmful pollutants, the most effective method of addressing air pollution in Tolworth is undoubtedly at the source.
Economic Context Kingston’s Economic Growth and Development Strategy 2018-2025 (EDSG) identifies Tolworth as a ‘hidden gem in the borough’s economy” [6], having had the highest rate of employment growth in the borough between 2010 and 2015. Tolworth’s economic strength is predominantly attributable to it’s three business parks which are home to a rich mix of companies, including nationally significant operators such as New England Seafood. Although enabling further economic growth in Tolworth is recognised as an essential part of Kingston’s future vision, it is also emphasized that the environmental impact of the A3 must be reduced via significant investment. It is also noted that Tolworth Station is currently an underutilised asset. A more regular train service would boost the local economy and reduce air pollution.

Flood Risk Tolworth is home to the Hogsmill River, which rises up 3 miles south east in Ewell, as well as the Bonesgate Stream and Tolworth Brook (Surbiton Stream). These watercourses all present a risk of flooding. The map opposite has been created using fluvial flooding data from the Environment Agency and depicts areas with a 1 in 100 chance of flooding per year (Zone 3) and areas with a 1 in 1000 chance of flooding per year (Zone 2). In 2018, the UK State of the Climate report contained several indicators which show that our climate is gradually becoming wetter.
Heavier rainfall, combined with new developments in the area, will put an increased pressure on Tolworth’s existing drainage infrastructure. Although new green infrastructure which incorporates Sustainable Drainage Systems (SuDS) could help mitigate some of this increased flooding risk, “further landscape interventions are required to slow, store and filter water: reforestation, wetland creation and re-meandering of rivers as catchments, serving to alleviate floods and droughts, slowing the surface water run-off, allowing it to filter and store, recharging aquifers, and creating wildlife habitat.” [7]

Biodiversity Tolworth is home to a wealth of wildlife. “Brown argus and white-letter hairstreak are amongst the butterfly species recorded at Tolworth Court Farm. Reptiles and amphibians, kestrels and woodpeckers are regularly seen by the people that walk through it’s countryside. Hidden gems include the much rarer saproxylic (of dead wood) jet ant Lasius fuliginosus, a species only found at one other site in the borough.” [8] Parts of Tolworth “are important examples of relict habitats, such as the traditional field systems and ancient species-rich hedgerows of Tolworth Court Farm Fields LNR.“ [9] The Hogsmill is an internationally rare type of chalkstream river, one of only two hundred in the world.
The Hogsmill acts as a vital wildlife corridor for the movement of animals within an urbanised context and almost a quarter of the UK’s dragonfly and damselfly species have been recorded along it. Against a backdrop of increasing widespread biodiversity loss, one recent report indicates that “Britain has lost half its wildlife” [10]. “The guiding principle of the Kingston Biodiversity Good Practice Guide is to allow no further net loss of biodiversity and achieve positive gain.” [11]. Local conservation projects which aim to increase native animal populations, such as Citizen Zoo’s plans to reintroduce water voles back into the Hogsmill River, should be supported by the Local Authority.

Access to Nature Areas designated by local authorities in England for their importance to biodiversity and public experience of nature are known as Sites of Importance for Nature Conservation (SINCs). Although this title is non-statutory, it does afford designated land a higher level of protection within the English planning system. Greenspace Information for Greater London (GiGL) is the custodian of SINC information in the capital and note the definition of Areas of Deficiency (AoD) in Access to Nature as follows: ‘Areas where people have to walk more than one kilometre to reach an accessible wildlife Site of Metropolitan or Borough Importance’ [12] Under this definition, given in The Mayor’s Biodiversity Strategy (2002), Sites of Local Importance for Nature Conservation are not included and have therefore not been identified in the SHEDx areas of deficiency map opposite.

Access to Public Open Space The London Plan, the spatial development strategy for Greater London, sets out maximum distances which residents should have to travel to access public open space, as categorised by the descriptions in the table below [13].
Local Parks and Open Spaces
Areas which fall outside of these maximum distances are defined as areas of deficiency in access to public open space.
4. Raeburn Avenue Open Space
In Tolworth large areas of deficiency lie to the west of the study area. Although much of this space is geographically within 400m of public open space to the south, the A3 acts as a barrier to access and travel distances are substantially further. Although Tolworth Court Farm Fields Nature Reserve does qualify as a district park in terms of size, it’s character as a Borough Grade I Site of Importance for Nature Conservation is not typified by the district park description below.

Planning Policy Context - Regional The All London Green Grid (ALGG), a supplementary planning document (SPD) to the London Plan, provides a spatial planning policy framework for optimised GI in Kingston upon Thames and Tolworth. Key recommendations in the ALGG include the restoration of grazed floodplains, completion of the Hogsmill River Walk through to the River Thames and the promotion of productive landscapes which promote healthy living, including the setting up of public urban farms. The ALGG also makes reference to local organisations which should be supported. These include the Kingston Permaculture Reserve (Project No. 9.2.15), Transition Town Kingston (Project No. 9.2.36) and Kingston University (Project No. 9.2.37) Since the ALGG was published in 2011 several of these opportunity projects are still outstanding. Partners including local conservationists, educational facilities, community groups and volunteers should be fully supported in their efforts to complete any outstanding ALGG projects.
Identified GI Projects - All London Green Grid
1. Project No. 9.2.12 - Elmbridge Meadows
“Improvement of a valuable pubic space by the restoration of the flood plain. This will improve drainage of boundary properties by creation of a series of seasonal ponds and reinstatement of drainage ditches into the Hogsmill, creation of a community orchard.”
2. Project No. 9.2.13 - Six Acre Meadow
“Potential for realignment and habitat management. This will improve visibility, amenity value and biodiversity.”

Context - Local A new Local Plan for Kingston upon Thames, which will guide future development in the borough up until 2041, is currently at an early stage of public engagement. It is important that the new Local Plan highlights the value of Tolworth’s existing open spaces, within the context of increased housing targets as set out in the GLA’s emerging London Plan.
Identified GI Projects - Tolworth Area Plan
1. “To really promote well-being and healthy streets the Tolworth Broadway area requires a bolder, larger scale and greener intervention than the current situation”
2. “Broker improvements to Broad Oaks public realm.”
Until the new Local Plan is adopted, in late 2021 or early 2022, Kingston’s Core Strategy remains the key planning document for development in the borough.
3. “Options for A3 Underpass include:
The Tolworth Area Plan (TAP), which was subject to public consultation sets out a high-level vision and a flexible framework for future change in Tolworth. A key recommendation from the TAP is the creation of a continuous public walking and cycling route, along the Hogsmill River, which connects up a wealth of existing Metropolitan Open Land (MOL) such as Tolworth Court Farm Fields Nature Reserve.
4. “Redesign car park to create an attractive greener
Further recommendations include the delivery of enhanced MOL entrances to signpost to nature, a network of centralised ‘seed to table’ food projects based out of local allotments and the delivery of new GI through improvements existing public spaces such as the Broadway and Broad Oaks.

setting to station, with improved parking layout, bicycle parking and introduction of sustainable drainage systems and tree planting.”
5. “Activate the edges of local leisure assets and
landmarks that are located along key routes leading to, and within open space”

Existing Green Infrastructure in Tolworth Areas to the northeast and southeast of the SHEDx study area are designated as Green Chain. â&#x20AC;&#x153;Green chains consists of continuous open space linkages, including areas of metropolitan open land (MOL), parks and river corridors which link into strategic networks of open land extending throughout the wide regionâ&#x20AC;? [16].
Areas to the south west and north west of the SHEDx study area are more urbanised and contain smaller pockets of green which are typically found on or adjacent to major roads such as the A3 and Ewell Road.

In 2018 London mayor Sadiq Kahn set out a vision for the city to achieve at least 50% green cover by 2050. In 2019 this ambition was further backed as London was declared the worldâ&#x20AC;&#x2122;s first National Park City.
New green infrastructure opportunities identified in this document could contribute to an additional green cover of 14.5 hectares, mostly attributable to the installation of new green roofs (please refer to page 63).
A desktop study of the SHEDx impact area (678 hectares) shows that it currently has total green cover of 328 hectares. This accounts for an existing green cover of 48%.
Undertaking such green infrastructure projects could increase the SHEDx impact area green cover to 50.5%, in line with the mayorâ&#x20AC;&#x2122;s aspirations for London as a National Park City.
Although this is a good percentage, due mainly to the large green open spaces south of the A3, it still falls under the mayors 50% target.

Community Ideas on Green Infrastructure As part of the SHEDx project, The Community Brain has been asking the public about existing and proposed green infrastructure in Tolworth. A community ideas event held at the top of Tolworth Tower revealed that many local residents were unaware of large public open spaces to the south of the A3, including Kingston’s largest nature reserve Tolworth Court Farm Fields. A separate online SHEDx green survey further revealed the underutilisation of Tolworth’s public open spaces. Tolworth Court Farm Fields ranked in 6th place, with survey participants indicating that they would often prefer to travel out of the borough to visit large open spaces such as Richmond and Bushy Parks.
The most underutilised public open space in the online survey was Kings George’s Field, which received no mention in the poll below. One participate noted “I don’t go over the A3 to visit King Georges Field and Tolworth Farm to walk the dog as its so unpleasant”. The Hogsmill River Walk was the most popular local open space, however feedback also indicated that residents would like to see it made more accessible and clean. Survey participants noted that the existing walk is very fragmented and suggestions were made for a single route to encourage both walking and cycling. Requests for new wayfinding to existing public open spaces echo suggestions from both the All London Green Grid and Tolworth Area Plan.

In addition to gathering community feedback on Tolworth’s existing public open spaces, The Community Brain has also been asking local residents and businesses for their ideas on new green infrastructure.
Requests for new allotments also featured in the survey. The SHEDx study area contains four allotments; Tolworth Main (4ha), Knollmead (2.5ha), Raeburn Avenue (1ha) and Ladywood Road (0.4ha), all of which are currently council run.
Participants in the online SHEDx green survey voted strongly in favour of new street trees, as per the poll results below. This ties in well with the council’s stated ambition “to plant at least 1500 new trees over the next three years.” [17].
The council’s Allotment strategy 2008-2018 stated “Kingston has a waiting list of 247 people for the existing 1200 plots on 23 sites across the borough. The Open Space Study undertaken by WS Atkins in May 2006 identified that to meet the needs of under served areas and increased demand resulting from population growth a further 14.34ha of allotment land would need to be brought into use.” [18]. The 2018/ 2019 waiting list number has increased to 374. It is recommended that the council’s existing allotment strategy is brought up to date to reflect changes since it was last published in 2008.
Other popular ideas for new green infrastructure included more green walks, wildflower meadows, native tree plantations and mini forest walks. These GI ideas might all be incorporated into improvement works to the Hogsmill River Walk.

Community GI Mapping and GI Co-design As part of the SHEDx project, the Community Brain has been working with numerous courses at Kingston University.
In addition to the analysis work of BA Geography, MA Architecture students have also been designing new GI features for Tolworth.
In late 2018, BA Geography students undertook street surveys in Tolworth to gather community thoughts on potential new GI.
In 2018, MArch Unit 5 students designed four mobile gardening sheds to transport tools, soil and plants to community greening projects in Tolworth.
In 2019, BA Geography students have been asking the public their thoughts on new wayfinding features in Tolworth, with the potential to direct more visitors to the currently underutilised green open spaces south of the A3.
In 2019, MArch students have been designing proposals for a new nature hide, for the Tolworth Moated Manor Site (SINC Grade I), which might incorporate new GI features such as green walls and roofs.
Wayfinding features could also be a way of introducing new GI into Tolworth, such as planters with directional signage to green assets.
Subject to the neccesary approvals, the winning studentâ&#x20AC;&#x2122;s nature hide is proposed to be built on site at Moated Manor in early 2020.

A Hierarchy of New Green Infrastructure The London Environment Strategy, published by the GLA in May 2018, sets out a series of actions which the Mayor is taking to improve the environment for all Londoners.
Similarly, new green infrastructure in Tolworth should be planned and implemented as a hierarchy of interconnected interventions.
“Action will be taken now to plant more trees, make green spaces more accessible, and ensure more green roofs and green features are designed into new developments. Local authorities and community groups will be supported to manage and value London’s parks and biodiversity better” [19].
The next chapter ‘Green Infrastructure Opportunity Areas’ makes a series of suggestions for new green infrastructure which reduces in scale from large interventions, such as habitat management and floodplain restoration, to small interventions such as pocket parks and street planters.
The strategy recognises that the adverse effects of climate change, toxic air, noise pollution and threats to our green spaces are intertwined and complex issues with no quick fixes.
By enabling these opportunity projects Tolworth could enjoy a range of benefits, as mentioned at the start of this document and recapped below.

Green Infrastructure Opportunity Areas Introduction This audit has identified 25 opportunities to create new, or improve upon existing, green infrastructure features within the SHEDx impact area boundary. In this chapter the projects are grouped, numbered and mapped according to size and complexity under the following hierarchy: - Outstanding Opportunities from the All London Green Grid - Green Corridors - Street Trees - Green Roofs - Green Walls - Rain Gardens - Pocket Parks and Planters
Tables containing more detailed summaries of each project, including cost estimates and potential risks, can be found at the end of each sub category. Factors considered in identifying the green infrastructure opportunity projects include: - Community suggestions - Guidance from key documents including the All London Green Grid and Tolworth Area Plan - Areas of deficiency maps (pages 25 and 26) - If the space is a RBK land-holding interest - The likelihood of below ground services - Current space usage and security - Local species extinctions - Existing footfall levels - Air pollution levels - Risk of flooding

Outstanding Opportunities from the All London Green Grid A series of project recommendations from the All London Green Grid ‘Arcadian Thames Area Framework’ are yet to be fully realised. These projects would deliver a wide range of benefits to Tolworth including community involvement, improved biodiversity, food growing, flood storage, particulate dispersion and the provision of new local amenities.
One project (GI Opportunity Project No 5) would enhance the biodiversity value of the Tolworth Moated Manor Site (Borough Grade I SINC) by introducing a traditional hay meadow management scheme with aftermath grazing. This prescriptive management technique reflects the site’s rich history, while also greatly benefiting an increased diversity of wildflowers which have seen a 97% drop since 1945. Local volunteers would be trained on how to traditionally scythe the area.
Proposals for a traditional hay meadow with grazing at the Tolworth Moated Manor Site (GI Opportunity Project No 5).

GI Opportunity Project Description
Potential Benefits
1.
Improvement of a valuable pubic space by the restoration of the Elmbridge Meadows flood plain. This will improve drainage of boundary properties by creation of a series of seasonal ponds and reinstatement of drainage ditches into the Hogsmill, creation of a community orchard and removal of invasive species (Japanese knotweed and Himalayan Balsam). Potential for regrading of the Hogsmill river bank to create a more natural profile with lowered riffle areas allowing access and amenity.
2.
Potential for realignment and habitat management. This will improve visibility, amenity value and biodiversity.
3.
Continued community stewardship of an acre of formerly waterlogged land in the Knollmead Allotments, now a site of special ecological and cultural value. Nurturing a mature forest garden with some 40 traditional fruit varieties and various other productive plants, alongside natural woodland, hedgerow, meadow and pond habitats. Working with nature to inspire and empower residents to be resourceful in addressing local and global problems.
4.
As part of a completed drainage project, the University sports ground at Tolworth Court has sacrificed a practice pitch which is often wet and boggy. It is proposed that this area be remediated into a species-rich wet meadow area, which will link the Hogsmill river to other green space in the area.
5.
Conserve existing biodiversity and archaeological remains, especially organic material in waterlogged deposits. Restoration of the moat by desilting, tree and shrub management reprofile banks to original shape (or near as). Maximise biodiversity value of the site by managing habitats to increase diversity, especially in the context of the Hogsmill Green Lane. Provide public access by installation of pedestrian gates and secure access for site management machinery.

Eight miles of native wildflower verges were planted by Rotherham Council. Photo source: Pictorial Meadows
Green Corridors UK native wildflower verges could be a low cost and low risk green infrastructure intervention which would bring a range of benefits to Tolworth, including improved appearance and biodiversity as well as particulate dispersion. Since 2013, Plantlife has been campaigning for wilder roadside verges. “It said safety and access considerations along with a desire for “neatness” and the logistics of litter-picking had resulted in authorities adopting an overzealous approach to keeping verges short.” Plantlife said a “cut less, cut later” approach by councils and highways authorities could significantly improve the health of the UK’s verges” [20]. It might also lead to potential cost savings in mowing costs.
In line with the Mayor’s Transport Strategy, to increase biodiversity, Transport for London are currently running a trial of native wildflower verges along two red routes, in Redbridge (A406) and Hillingdon (A40). If the trial is successful, TfL ‘hope to expand to other suitable verges along red routes in 2020 and beyond” [21]. The section of Kingston Road shown opposite (GI Opportunity Project No 8) is a TfL red route and would therefore qualify as a suitable verge. Railway embankments between Chessington North and Malden Manor (GI Opportunity Project No 7) are also a great opportunity for UK native wildlife and Network Rail recognised this in their 2018 review ‘Valuing nature - a railway for people and wildlife’.

Street Trees Trees are very important. In addition to creating more attractive public spaces they provide a variety of benefits, as outlined in the diagram below. The local authority owns an estimated 12,000 street trees, in addition to those planted in public open spaces, school grounds and council housing estates. The RBK Tree Strategy 2015-2021 notes a planting shortfall of over 500 trees in the past 5 years [23] and aims to “plant at least 1500 new trees over the next three years”, including 600 new trees in the winter planting season of 2019/20 [24]. The council, in partnership with local groups, have also been working on plans to increase community tree planting in the borough.
The benefits of street trees. Photo credit: Your Leaf
Under new proposals, the council will train and support a network of local tree wardens to identify potential locations and species, fundraise for the cost of new trees (£350 per tree) and organise community planting projects. [25] Although there are many opportunities for new trees to be planted, constraints and practicalities such as existing underground infrastructure will need to be assessed on a case by case basis. In Tolworth, an area which suffers from some of the worst pollution in the borough, new street trees should be prioritised in areas of low tree canopy cover which are close to schools, as identified in the map opposite. This was one finding of the council’s recent Citizen’s Assembly on Air Quality. [26]

Green Roofs New green roofs in Tolworth could benefit the area in a number of ways including improved surface water storage, improved biodiversity through habitat creation and particulate dispersion. The Urban Greening Factor, a planning policy tool from the London Plan, recognises that quality green roofs are a great way of creating larger areas of quality GI in new developments. The map opposite identifies potential green roof opportunities in Tolworth, and was undertaken as a desk-based study utilising aerial photography. A total of 294 roofs were identified as appearing flat or below a 20 degree angle and therefore suitable for green roof installation. Building owners, including RBK, should undertake a detailed structural assessment if they are interested in retrofitting a green roof.
Maintenance, irrigation and access should also be assessed to ascertain which of the following five green roof types might be viable: Extensive Green Roofs Lightweight, low maintenance system with a shallow growing medium depth of under 100mm. Extensive Sedum Roofs Similar to extensive but designed specifically for sedum, generally using pre-grown mats/blankets. Biodiverse Roofs: Similar to extensive but designed specifically to benefit local wildlife. Semi Intensive Green Roofs A deeper growing medium, of typically over 200mm, allows for a greater range of vegetation. Irrigation and maintenance may be required. Intensive Green Roofs Roof gardens with public access and amenity space. Irrigation and maintenance required. [27]

Green Walls Green walls are visually stunning GI interventions which can also mask unattractive building elements, infrastructure and public spaces. Placed correctly, they are beneficial for particulate dispersion and can also support local biodiversity. Although not the cheapest GI feature, the most cost effective and low risk method of achieving a green wall is with climbers which grow up from soil filled planters at the base of the wall. More expensive systems, such as the image below, utilise modular green wall cassette systems. These systems, which are sometimes completely non soil based or hydroponic, rely on complex irrigation systems and regular intensive maintenance. Building owners wishing to install a green wall should consider the wallâ&#x20AC;&#x2122;s aspect and potential water sources. Walls facing north use less water but will be more limited in terms of planting.
For modular cassette systems a structural engineer should always be consulted to inspect the existing wall. Although planning permission for green walls is not usually required, building owners should also check with the local authority. In Tolworth new green walls should be located in areas of high visibility, and pollution, for maximum effect. The map opposite makes suggestions for three such locations between Tolworth Roundabout and Tolworth Station. As nitrogen dioxide (NO2) levels are highest at the roundabout (please refer to page 16) it is proposed that a lower risk climbing variety is installed here. The remaining two locations would be proposed as modular systems. All three install locations belong to private landowners and therefore permissions and agreements would have to be sought. Installations above a road might require a road closure.

Rain Gardens Rain gardens are shallow planted channels, most often found in urban and suburban contexts, which can reduce the risk of surface water (pluvial) flooding and also help mitigate the impact of pollution through particulate dispersion. Rain gardens are a form of Sustainable Drainage System (SuDS) which improve the aesthetics of a grey streetscape, whilst also providing much needed protection and forage for local wildlife. A typical rain garden build up involves a top freeboard layer of between 200-300mm, a middle topsoil layer of between 200-500mm and a bottom sub-base layer of between 100-500mm deep. In areas of free draining sub-soil, or small catchment areas, it might be possible to completely eliminate the sub-base layer.

Rain gardens offer opportunities to plant a wide range of perennials, and can absorb up to 30% more water than a lawn [28].
For these reasons it is unlikely that anyone else other than the local authority could install new rain gardens Tolworth.
In Tolworth, rain gardens could be installed in areas which are predominantely hard surfaced, are prone to surface water flooding and are also close to main roads with high particulate levels.
Although they require little maintenance, in regards of watering, rain gardens do require a suitable pruning regime to keep them from becoming hazardously overgrown.
Due to the subterranean nature of rain gardens, barriers to retrofitting can be considerable. They include the existence of underground services, existing pedestrian, cyclist and motorist routes and the requirement for regular maintenance.
With the advise of a horticulturalist, more appropriate varieties can be chosen which do not have a tendancy to spread horizontally, and a reasonable maintenance plan for the rain garden can be established.

Pocket Parks and Planters New pocket parks and planters are a very cost effective way to deliver a wide range of benefits to communities in Tolworth.
New planters are a simple, low risk method of visually enhancing an area by greening any existing grey public spaces.
In addition to providing new local amenity space, pocket parks support biodiversity and could also provide an opportunity for communities to grow their own food locally.
New planters, placed in areas adjacent to busy roads, have some ability to disperse particulate matter and also provide an excellent opportunity for community involvement and ownership.

The aspect of any new planting should be well considered as this will effect the type of varieties which will thrive in a given condition. Planters, by their smaller nature, are prone to periods of drought and planting should therefore be hardy and drought resistant. Where possible, existing water sources should be identified and utilised to mitigate the need for frequent watering during hotter periods. For both new pocket parks and planters, permission must be sought from the landowner. If supported, community-led planting promotes local cohesion and ownership which may well encourage longer term community maintenance and watering of the adopted planted areas.
In Paris, the local authority set up the Paris Greening Permit scheme in 2015. Under the scheme, 2500 residents identified areas of grey public space which was suitable for greening and applied to the local authority for a permit and guidance to undertake the works [29]. The local authority should be supportive of such community-led schemes and may wish to trial a Kingston Greening Permit in Tolworth. There are many sources of funding available for small community greening projects, including pocket parks, which are noted in the next chapter. TfL has also created a useful toolkit for greening Londonâ&#x20AC;&#x2122;s public spaces entitled â&#x20AC;&#x2DC;Small Change, Big Impactâ&#x20AC;&#x2122; [30].

Overview of Suggestions for the Local Authority Protect and Enhance Existing Public Open Spaces Ensure that Tolworth’s existing public open spaces, especially Kingston’s largest nature reserve Tolworth Court Farm Fields, are protected in Kingston’s emerging new local plan. Raise awareness of Tolworth’s existing public open spaces, especially Kingston’s largest nature reserve Tolworth Court Farm Fields, through new wayfinding and enhanced entrances. Re-establish partnership with Greenspace Information for Greater London (GiGL) to ensure better insight for the emerging new local plan. Data covered includes detailed information on access to public open spaces, access to nature, habitat data and species records. Ground Maintenance Contracts Opportunities to review the grounds maintenance contract should be taken to support green infrastructure and biodiversity outcomes including appropriate maintenance arrangements Update Existing Allotment Strategy Update the current Allotment Strategy (20082018) to reflect changes since it was published in 2008, including an audit of all current stock and waiting lists. Help Implement Outstanding Opportunities from the All London Green Grid Support local partners including conservationists, educational facilities and community groups in their efforts to complete outstanding projects from the All London Green Grid Arcadian Thames. (Please refer to pages 50-53). Support local conservation projects which aim to increase native animal populations, such as Citizen Zoo’s plans to reintroduce water voles back into the Hogsmill River.
Green Corridors Explore the opportunity of partnering with Network Rail to help improve biodiversity along railway embankments as part of their new Biodiversity Delivery Plan. If Cross Rail 2 is delivered in Tolworth it would need to provide no net loss of biodiversity by 2024. (Please refer to pages 54-57). Explore the opportunity of partnering with TfL regarding their UK native wildflower verges trial along red routes in London. (Please refer to pages 54-57). Street Trees Ensure Tolworth, an area which suffers from some of the worst pollution in the borough, is planted with new street trees, prioritised in areas of low tree canopy cover which are close to schools, (Please refer to pages 58-61). Green Roofs Explore the opportunity to retrofit green roofs onto council owned buildings. (Please refer to pages 62-65). Green Walls Explore the opportunity to retrofit green walls onto council owned buildings. (Please refer to pages 66-69). Rain Gardens Explore the opportunity to install new rain gardens in Tolworth. (Please refer to pages 70-75). New rain gardens should ideally be incorporated into schemes where the local authority is already undertaking excavation works to roads and pavements, such as for new cycle routes. Pocket Parks and Planters Support local partners undertaking small scale community-led greening projects. Explore the opportunity of trialling a ‘Kingston Greening Permit’ in Tolworth.

DIY Green Infrastructure at Home Gardens are an important part of green infrastructure. â&#x20AC;&#x2DC;In fact, our gardens account for about 25 percent of the land in most cities. And because more than 80 percent of the UK population lives in a town or city, we can make a difference by ensuring that every available space in our front and back garden contains planting, and that we carry out sustainable practicesâ&#x20AC;&#x2122; [31] If planned properly, gardens can provide a variety of benefits in urban and suburban areas including; Cooling the Urban Environment Gardens help reduce the urban island heat effect through aerial cooling (from shading) and via evapotranspiration (water loss through leaf pores). Insulating Buildings from Heat Loss The planting of trees, hedges and other thick vegetation can thermally buffer a building and help reduce the surrounding air speed. Prevention of Urban Flooding Planting helps to intercept heavy rainfall, slowing rainfall and reducing the pressure on urban drainage systems. Excessive hard surfacing, with no sustainable drainage systems, can greatly increase the risk of flooding in urban areas.
Supporting Human Health Gardening has been proven as a way of improving both physical and mental wellbeing, particularly with regard to community gardening projects. Green spaces in urban environments can help alleviate stress, improve cognitive function and generally provide a peaceful setting in which to socialise and relax. Increasing Urban Biodiversity Domestic urban gardens support a substantial range of wildlife. There is now evidence to suggest that some declining species, which were once common in low intensity farmland, are now more abundant in domestic urban gardens. These include the hedgehog, song thrush and common frog. Siân Moxon, a senior lecturer at the Cass School of Art, Architecture and Design founded a project called Rewild my Street which is accessible at: www.rewildmystreet.org The site provides great guidance on how to adapt homes, gardens and streets to encourage native wildlife in urban settings.

Next Steps Project Guidance Kingston Council recently commissioned a community projects guide, entitled Reimagining Kingston Town Centre’s Streets & Spaces, which aims to help interested local partners to codeliver projects. Much of the practical advice contained in the ‘Making it Happen’ chapter, between pages 25-39, is very relevant to partners wishing to undertake new GI projects in Tolworth. The guide can be found online at: www.kingston.gov.uk/streetsandspaces
Funding Available funding options should be explored as soon as the GI project has been chosen. Most funders ask for a clear project budget and this should be assembled in any case. Key funding opportunities, taken from Reimagining Kingston Town Centre’s Streets & Spaces, can be found in the appendix at the end of this document. Where projects will deliver direct benefit to local businesses it may well also be appropriate to seek sponsorship or part funding for small scale GI, such a new raised planters.
Project Identification It is important to note that the opportunity projects outlined in this document are not exhaustive and that local partners are very much encouraged to propose their own GI interventions in Tolworth. Communities should be encouraged and enabled to come together to green the grey in areas where they live.
Engagement All projects will be subject to further consultation and agreements with the relevant stakeholders including landowners, the local authority and local partners. To aid project success, an engagement plan should be developed after funding is secured. Feedback from the engagement activities should also help develop ideas.
Consider Other Stakeholders and Collaborators A successful project is one which maps out all key stakeholders at an early stage. Stakeholders might include the landowner, the local authority, the highways authority and neighbours. Collaborators might include conservation organisations, environmental groups, educational facilities, businesses and community groups.
Additional Surveys Some of the GI typologies in this guide will require further survey work. Structural surveys will be required for green roof and green wall installations and proposals for new street trees and rain gardens will most likely require a survey of existing underground services. Sight lines and visibility splays on highways may also be assessed.

Design For most of the GI opportunities raised in this document, design advice should be sought. This might include planting advice which is beneficial for biodiversity and wildlife, such as the bee-friendly borders opposite which were designed by local business start-up Janice Horslen Garden Design. The design advice of horticulturists, conservationists, landscape architects and landscape managers will help support long term project success through the appropriate selection of species for particular conditions. Independant environmental consultants might also be consulted prior to the retrofitting of any green roofs or green walls. Planning permission may well be required for some GI interventions and thus this should be established with the local authority at an early stage. Townscape assessments may also be required in some instances so this should also be ascertained.
Maintenance Maintenance is fundamental to all of the GI opportunities outlined in this document and needs to be considered at the project outset. For public spaces community planting and adoption of GI is encouraged however some of the opportunity projects identified, such as rain gardens, will require regular maintenance by the local authority for safety purposes. More complex GI projects, such as green walls and green roofs, may also require specialist maintenance contracts. A clear maintenance plan should be in place prior to project delivery and parties responsible for undertaking all maintenance elements identified.
