KICKSTARTING RESILIENCE AT BUCKINGHAM CANAL

Context – The Buckingham Canal The Buckingham Canal is a manmade, saltwater, navigation canal that runs parallel to the Coromandel Coast in a northsouth direction. It was built in different phases from 1800 until 1882 with a length of approximately 800 km reaching from Vijayawada to Marakkanam. Within the Chennai metropolitan area, the canal connects the three rivers – Kosasthlaiyar, Cooum and Adyar. Though primarily constructed for navigational purposes, the canal also helped significantly to manage floodwater. Today, however, the canal faces severe pollution due to solid and liquid waste disposal. In addition, numerous business buildings and unplanned residential settlements encroach on its banks. This reduces the width of the canal and decreases its capacity as flood management infrastructure to retain floodwater in case of heavy precipitation or storm surges. Moreover, the canal’s former functions offering a trading space on its waters where the local population developed their livelihood, as well as a place for recreation and belonging have been lost. Over the years, various governmental agencies have struggled to revive the canal and continue to do so to this date.

‘Cities Fit for Climate Change’ Against this backdrop, the initiative ‘Eyes on the Canal’ was brought into life. It focuses on reimagining the Buckingham Canal in Chennai as part of the global project ‘Cities Fit for Climate Change’ (CFCC). CFCC is a global project implemented by the Deutsche Gesellschaft für Internationale Zusammenarbeit (GIZ) GmbH on behalf of the German Federal Ministry for the Environment, Nature Conservation and Nuclear Safety (BMU). It forms part of the International Climate Initiative (IKI). The project also cooperates with the German Federal Ministry of the Interior, Building and Community (BMI). The global project CFCC strengthens cities as key actors in sustainable development. It collaborates mainly with its three partner cities, Santiago de Chile in Chile, Chennai in India and Durban (eThekwini) in South Africa. Besides supporting the implementation of climate-proofing activities in its partner cities and strengthening global exchange on low-carbon and resilient urban development the project developed a Climate-Proof Urban Development Approach (ClimPUDA). ‘Eyes

on the Canal’ – An Open Ideas Competition on Reimagining Chennai’s Buckingham Canal

‘Eyes on the Canal’ is an initiative for participatory planning to make the Buckingham Canal a liveable place for the residents of Chennai. The initiative involves various activities such as awareness walks and community engagement meetings to generate interest and ownership for the canal, which has suffered from collective abandonment. Within this initiative, the global project CFCC launched an ‘Open Ideas Competition on Reimagining Chennai’s Buckingham Canal’, which was supported by three local non-governmental organisations (NGOs): The Urban Design Collective, Agam Sei, and WeBe Design Lab. The competition is implemented in collaboration with the Greater Chennai Corporation (GCC), the municipal administration. The Open Ideas Competition aimed to find solutions to improve the environmental situation of the Buckingham Canal in the south of Chennai. A total of 296 registered for the competition and 81 participants finally submitted feasible and creative solutions to tackle climate change and upgrade local livelihoods for a 3.5 km stretch of the canal. The neighbourhood located next to the selected canal stretch is highly diverse in terms of social composition and land use. It features informal residential and business buildings in a poor area, a mixed middle-class area and larger IT office buildings. In short, it creates a particular context that requires tailor-made solutions. The competition took a holistic view of the canal and was designed as an integrated exercise, which was influenced by and targeted at experts as well as citizens from a multitude of backgrounds. The ideas competition opened new ways of discussing and working on urban development issues in Chennai, promoting participatory planning to enhance public engagement.

EXECUTIVE SUMMARY

KICKSTARTING RESILIENCE AT BUCKINGHAM CANAL

Chennai, like various coastal cities has been experiencing the impact of climate change and has seen various weather anomalies and recently faced a 1 in a 100 year flooding event in 2015. Continuing at the current trajectory, Chennai will soon experience a 1 meter rise in sea level due to which the city can expect a huge chunk of approximately 144 sq. km. of land being inundated near its coastal areas. A flooding disaster at this time can cause a storm surge of up to 6.8 mts. resulting in a loss of over Rs 7,00,000 crores.[1] The first phase of our project studied future shocks and stresses that could affect the city and identified Buckingham Canal as an asset that has already been providing resilience and is need of strengthening to flood-proof Chennai. We proposed to re-imagine the Buckingham Canal as a means of making Chennai climate proof by taking urgent steps to address the challenges arising out of unpredictable climate, rising sea levels, future storm surges and possible inundation of the coastal areas of Chennai. Our proposal looked at different industrial, residential and ecological landscapes that the canal runs through in Chennai and based on land use suggested strategies to combat the perils of climate change at a regional level. Our strategies for a planned water sensitive future development in South Chennai included developing decentralized sewage treatment systems for under-served areas and protecting and restoring Pallikaranai marshlands. and developing a water management toolkit to address climate change.

Limit Urbanization

Expansion Of Flood Area

A berm wall will help in blocking the water from overflowing into the city during a period of flood or disaster.

By limiting urbanization, green spaces around Chennai can be preserved and help with regulating the micro climate.

Expansion of Flood Area will decrease the risk of flooding by increasing the capacity of water to be conveyed .

No Infrastructural Waste

Reduction of Paved Areas

Constructed Wetlands

Promoting reuse of wastewater in industries and regulating waste dumping.

Reduced Pavement will help in reduction of surface water runoff . Thus there will be a lower risk of flood.

Constructed wetlands can compliment insufficient sewage treatment plants

Re-naturalization of Banks

Natural Filters for Water Purification

Retention-ponds

Natural Vegetation Buffer helps protect the quality of water & also stabilizes the shoreline & reduces erosion.

Mangrove enclosure near the river will protect the shoreline from storms and help with purification of runoff water.

Rainwater Catchment areas helps in harvesting water for the longer period of year.

Infiltration fields and strips with above ground storage

Rain garden

Visibility of Asset

Vegetation on streetscapes reduces the impact of heat island effect while providing shade as well as creating public parks .

Rain gardens are a garden of native shrubs and perennials that are planted in a small depression. They will temporarily hold and soak water from roofs and roads.

Employing water as a functional aspect to heritage or prominent buildings helps in creating awareness.

Bioswales

Raising The Ground Water Level

Constructing buildings on stilts will help in preventing flooding in buildings .

Bioswales can treat surface water from the street and slow down flooding of drains and waterbodies.

Porous Pavements are created with a range of sustainable materials that allow movement of water through the surface.

Rain water harvesting

Green Roof

Use of Ground Cover and Shrubbery

Rainwater collected from roofs and man-made hard surface would help in storing water for dry periods .

Green roofing systems will cater to solving problems like temperature increase and reduced habitat.

A greater percentage of soft scape in comparison to built scape will help with increasing ground water table.

TOOLKIT OF WATER SENSITIVE MANAGEMENT STRATEGIES Through the use of macro, local and community strategies, our toolkit of water sensitive interventions can be applied as a comprehensive urban-landscape strategy at different urban scales. City wide strategies such as a a flood prevention landscaped berm near Adhyar river, constructed wastelands to compliment insufficient wastewater treatment facilities, expanding flooding areas near water bodies, natural helophyte filters to treat polluted waters, a policy of limiting urbanization in flood prone areas and water based densification strategies can result in a resilient city. At a neighborhood level, banks of water bodies can be re-naturalized to stabilize shorelines, low impact development strategies such as retention ponds, green zones, artificial urban wetlands, water retention infrastructure and natural water purification plantations can increase climate resilience. At the street level we propose Infiltration strips, Bioswales, floating filtration islands in the canal, water squares, and advanced flood proof construction regulations to flood proof chennai. Policies that encourage implementation of rain water gardens, roof gardens and increased plantation at a building level can further flood proof the city at a granular scale and minimize damage from future events. In the next phase of the project, we further developed a few of these strategies (demarcated with a blue box) and demonstrated how they can be applied as a interim project.

STRIP 1.0

KICKSTARTING RESILIENCE AT BUCKINGHAM CANAL The competition entry was then followed by our project proposal which is discussed in this report. The project follows a phase wise strategy to achieve the following goals: • • • •

Re-imagining the Public Realm, Restoring Ecology, Prioritizing Environmental Sustainability and Fostering Community Participation all directed towards building a resilient city.

The project is divided into three major phases: Short Term Action Plan: which aims at activating the space and harnessing interest within the site through temporary improvements for quick wins Set of Resilient Green Infrastructure Interim Projects which take this interest forward to restore the ecology of the Buckingham canal and aim at its rejuvenation Long Term Vision Plan: that demonstrates the potential that can be generated through the previous steps.

SHORT TERM ACTION PLAN

The action plan aims at activating a chosen site on the banks of Buckingham Canal to create energy and dynamism and generate interest on the site within the community. This is done through the use of temporary interventions and pop-up urbanism that can be implemented now with limited funding. Through seasonal events and multipurpose spaces that can be programmed into a dynamic public space through out the year, the plan intents to pull people to the site kickstarting a relationship with the users and the canal edge. Through a menu of programming which has been developed while working with the residents of the area, the Strip 1.0, becomes a new public space in an existing urban wasteland.

ACTION PLAN • • • •

Create a new identity for the canal banks as public spaces. Encourage a diverse set of activities that involve all strata of the society. Revitalize existing unused urban spaces. Develop a bio-diverse and native ecosystem to make the canal more resilient and sustainable. • Enhance comfort and safety of the users through appropriate amenities, lighting and security. • Increase the community interaction with the site.

KICKSTARTING RESILIENCE AT BUCKINGHAM CANAL

LONG TERM VISION PLAN

The project aims at creating a ripple effect beginning with the short term action plan, then transforming into the interim projects and furthering into the long term vision plan. The Strip intends to create a green patch running below the elevated MRTS offering green open spaces to all the communities it passes through. This would offer Chennai's residents a renewed public recreational experience. The initiative will bring about a great shift in the lifestyle amenities offered to the people allowing for a healthier and fitter lifestyle. The Strip will also enhance pedestrian connectivity in the city that currently struggles with great challenges in the transport systems such as vehicular traffic and strikingly low footfall in the MRTS ridership. The green infrastructure suggested in the program will further climate proof chennai, increase its tolerance to future risks while adding much needed active green open space in the city. The design will offer the people a water front in the long run which can add greatly to the fabric and character of the adjoining neighborhoods. The long term vision explores various programmatic components and sets a framework for its execution. Community participation, ideas and improvements from the short term action plan and on going betterment of the canal become the pillars for the long termvision.

BUILDING RESILENCE THROUGH INTERIM PROJECTS After the activation of the site with the help of the short term action plan the project then proposes the introduction of interim projects for canal rejuvenation and water management on site. The integration of green infrastructure elements like bioswales, rain gardens, floating treatment islands and floating treatment wetlands work in tandem to create a holistic system to strengthen the canal and manage the storm water drainage into the canal.

COMMUNITY PARTICIPATION

The project envisions community participation of all stakeholders living near Buckingham canal, citizens of Chennai as well as all communities affected by floods and climate change. In order to involve the community into the process of rejuvenation of the canal, we have created and executed a set of surveys. In order to ensure maximum outreach, the survey was created in English and Tamil and circulated amongst the community through digital platforms and social media. Walks along with the survey sheets were also conducted at the Thiruvanmiyur station, the stretch between the Thiruvanmiyur MRTS station and the Kottupuram MRTS station. A community participation workshop was also conducted where the community was presented with the design intent of the project and were asked to respond to key concerns like safety, activities, concerns, aspirations etc. This survey was met with an unanimous agreement on the creation of parks, gardens, green trails food festivals and flea markets along the canal which have been incorporated in this proposal.

RAIN GARDEN

INTEGRATED WETLAND TREATMENT

CONCLUSION

Increasing Chennai resiliency and the rejuvenation of the Buckingham canal are long term and capital intensive projects. Through this project we have strived to focus on what is possible now through limited means to kickstart a larger momentum required to transform the canal into an asset that can help not just with flooding events but also become an integral part of the public life of the city

KICKSTARTING RESILIENCE AT BUCKINGHAM CANAL

Flood Protection â&#x20AC;˘ During the December 2004 tsunami the canal acts as a buffer and pulls in seawater into the canal . â&#x20AC;˘ During the 2015 floods the canal acts as a buffer zone and prevents adjacent areas of the city of Chennai from getting flooded.

Current Situation

Project Goals

Currently the width of the canal has been reduced to a mere 12-15 mtrs. in most parts. Untreated sewage is dumped daily into the canal making the water body a city nallah.

The main aim of the project is to rejuvenate the canal and deal with current issues of sewage dumping, flooding while also addressing the issues that will arise in the near future due to global warming. This can be achieved by revitalizing the canal, increasing green spaces, methodological waste segregation and treating the polluted canal water.

BUCKINGHAM CANAL : CURRENT STATE Buckingham canal is in a current state of neglect and deterioration. The canal was created as an inland transportation solution for the Coromandel coastal cities and also acted as a source of great relief during the droughts and floods faced by Chennai. The canal was created over a series of periodic excavations however design, maintenance and regulations works took a back seat during the planning for the canal. The state of the canal has deteriorated over time and remains completely ignored by citizenry and authorities alike. This state of detriment began by heavy silting due to serious cyclones that struck the coast. The problem of silting was further intensified by tidal flow from shallow beds of rivers and back waters. The canal travels through different types of soil, most of which are loose in character. Since the canal is unlined the sides began to slip further reducing the depth of the canal. Further factors such as lack of funds and shift of focus to road and rail transport added to the decline of the canal. The ignorance of the authorities to reevaluate and allocate sufficient funds for the maintenance of the canal created a scarcity of resources required for repair and rejuvenation. Today, Chennai dumps more than 60% of its untreated sewage into the canal. The wellbeing of the canal faces natural and man made challenges including weeding, silting, flow speed, sewage disposal, turbidity and encroachment.

KICKSTARTING RESILIENCE AT BUCKINGHAM CANAL

The current state of the canal affects not just the cleanliness in the surrounding areas, but also possess health hazards and makes its immediate surroundings dormant and detrimentally affects the cityâ&#x20AC;&#x2122;s urban fabric. The fact that the canal and its surroundings were not viewed as an asset and a great element for development, has given rise to haywire infrastructure around it, deterioration in the quality of its water, large unused areas with uncontrolled landscape, garbage dumping and many more such issues. While the canal, with its history and importance, should be a significant symbol of pride for the city, it lies in an extremely poor condition and now requires intense rejuvenation. To reverse the damage that has happened over the years, measures to compensate for the same need effective implementation, acceptance and consistency. Once restored, the canal and its surroundings can become an asset for the city. Overgrown Canal edge

KICKSTARTING RESILIENCE AT BUCKINGHAM CANAL

PROJECT FRAMEWORK The holistic aim of the project is to showcase alternate water management techniques which are micro solutions that can be applied at building, site and city scale to reduce the sewage and pollutants from entering the canal. This includes creating a network of resilient green infrastructure that treats run off along the edges of the canal as well as a robust system that treats the existing effluents and sewage being dumped into the canal to restore the quality of the water flowing into the canal. But to kickstart such a movement, it is imperative that the relationship of the community with the canal edge is first strengthened. To do so, the project proposes a two step process - A Short term action plan which can be implemented now and a long term vision which benefits from the learnings of the short term plan for permanent improvements. The methodology followed includes establishment of phases

and the segregation of goals into holistic and step wise processes. Concepts such as Tactical Urbanism have been employed to make sure the achievement of the 'now' goals. The framework for the design has broader parameters such as sustainability and resilience of the city at its core. Within these parameters the design intent of a renewed public space are placed. On guaging the success of initial temporary measures, a long term plan for a public canal waterfront can be created. Future smaller projects can be designed and implemented in conjunction with green infrastructure projects which result in a network of open space and result in climate proofing the city.

Long Term Vision

The Short Term Vision Plan along with Interim projects consist of ideas that can be tested and implemented through limited funding in the initial phase on a small chosen stretch along the canal banks in Adhyar.

The project imagines the entire stretch between the elevated MRTS tracks to be developed as a green spine connecting communities and encouraging a healthy, active lifestyle. Small programmatic components can be derived by understanding needs of adjacent communities and through learnings from the short term action plan.

Through pop-up urbanism and tactile urbanism methodologies, unused pockets along the canal edge can be activated through citizen led initiatives. Programming for this phase has been derived through constant interaction with the community to understand the kind of public space desired. During this phase GI projects such a bioswales, rain garden and a integrated wetland treatment system to treat the canal are proposed which can be scaled after evaluating its impact. These act as interim projects which can be further developed with a long term stratergy in place.

The Long term Vision Plan should be implemented by keeping in mind two principle ideas : â&#x20AC;˘ Restoring the Canal â&#x20AC;˘ Developing the unused areas around the canal to create a public asset The project does not propose what the new urban space should be, but rather sets guidelines for various types of public spaces to ensure the resultant space in universal, inclusive and sustainable.

THE SITE: STRIP 1.0 Locating the Strip 1.0 Site Context Generating a Collective Vision

Strip 1.0 is the beginning of activating the first site along the edge of Buckingham Canal in order to restore and activate it. Strip 1.0 is the first step working at the amalgamation of public realm and ecological sustainability and marks the foundation stone for a larger, well connected and invigorating public space with a ecological goal at the core.

LOCATING THE STRIP 1.0 The site selection for the demonstration of the proposal has been done keeping in mind the maximum impact and highest footfall. The parameters for site selection have been derived from Jan Gehl’s book “Cities for people” altered taking into consideration factors such as context and user group. The goal of the design process is not

Accessibility:

Unused urban spaces:

Proximity to amenities:

only qualitative in nature but also technically grounded. Considering the above the site criteria parameters have been divided into two major categories – qualitative and technical, which are further divided into secondary criteria.

The site must be easily accessible to pedestrian as well as vehicular thoroughfare owing to the presence of the OMR road along the length of the site. The future developements on the site must also work in alliance with the bigger idea of accessibility.The chosen site must have a fairly consistent and flat topography that allows for easy wheel chair access along with good walkability for pedestrian access. This will make the site inclusive in nature serving to all economic classes of the society. Other than the tangible physical access the site must also allow a direct visual access to the passers and the commuters of the MRTS.

The selected site should be unused and unfrequented by the citizens due to factors such as lack of shelter, comfortable seating, activities, cleanliness, etc. The site must not participate in the to and fro movement of the pedestrian traffic neither should it serve as a pause point for the same. Hence being classified as unused and inactive.

The site must be in tandem and in close proximity with MRTS stations. Public amenities see a large number of the population in a periodic fashion. Hence choosing a site adjacent to the same would subsequently mean high footfall in the public spaces designed around them. These spaces would not only satisfy the need of the encompassing areas but also create a prolific environment.

The site is surrounded by active spaces such as IT Parks, institutes such as the Institute of Mathematical sciences and the Press Institute of India and large institutions such as the MGR Film city. As a result of which, the site should be able to function as a breathing space.

High footfall region: As per a report created by the Times of India published in 2009, the daily footfall experienced by the Thiruvanmiyur MRTS station is a startling 7596 people ranking as the third busiest station on the MRTS. The proximity of the site to the station or one of a similar stature guarantees a good footfall on the site.

Safety Barriers The presence of the canal behaves like a natural barrier through landscape. This feature behaves like a safety feature and allows one to control the penetration into the site.

KICKSTARTING RESILIENCE AT BUCKINGHAM CANAL

Sense of belonging and commitment to the site:

The site but be surrounded by residential areas that could add to the demographic expected on the site. The site would hence have the potential and the location to serve the citizens residing around it by adding to the public amenities available to them within a given radius. Surrounding residential areas would create a set of population with a strong sense of belonging and a strong commitment to the utilization and revitalization of the site. This would be ideal for environmental initiatives such as the building and maintaining of Floating treatment wetlands and Bioswales.

08 01

Sewage Outfalls:

The sewage outfalls along the Canal require immediate attention. The selected stretch must house sewage outfalls that require immedate intervention.

TECHNICAL CRITERIA Convenience:

The site must be located close to the MRTS stations since it is very convenient for the people to access and participate.Convinience of the people becomes vital to the sucess of any intervention.

02 Development Plans :

Site must not interfere with any existing or future development. Also it shouldnâ&#x20AC;&#x2122;t have any detrimental impacts on neighboring land uses. The design for the site should in no way interrupt with the development of the new MRTS station proposed along it. On the contrary the two would function in tandem with each other.

03 Sizing and accommodation of functions

Site must be large enough to accommodate the following: A minimum number of garden plots to be viable in the long term A composting system Rainwater tanks Seating areas and shelter for gardens Garden beds including raised garden beds for people with mobility issues

04 Land Ownership and acquirement

The land owners for the plot must be government bodies or alike so that the process of acquirement for dedicated public spaces should be a smooth process. This further reflects as no costs in legal and compensation battles which could be utilised for the betterment of the design.

The site is adjacent to Buckingham Canal and has various institutions and residential areas in its vicinity. The average residing population accounted for during the 2001 census was 13% of the total population of Chennai. The stretch is located between a residential zone on one side and IT hub on another and hence has the potential to attract high amount of footfall during peak hours. Thiruvanmiyur MRTS is one of the few stations which has the highest amount of footfall within the network. During a March 2008 survey , 3246 people traveled in and out of Thiruvanmiyur station making it the 5th busiest station in the city of Chennai . The banks of the canal house an array of inhabitants. The canal acts as a divider between the contrasting strata of society. Along the western edge of the canal, people reside in simple homes belonging to the lower income groups of Chennai that many would call â&#x20AC;&#x153;encroachmentsâ&#x20AC;?. In the Kotturpuram stretch, the community shows great sense of belonging to the site and nurtures the subsequent open space between the canal and the houses as their very own backyard. The bank on the other side of the canal houses the MRTS stations and large institutions such a IIT Madras, Anna University and large IT complexes such as the Ramanujan IT complex. There is a varied and mobile crowd experienced by this stretch that becomes an ever transitioning part of site identity.

HIGH FOOTFALL ZONES AROUND The site is surrounded by prestigious and crowd pulling institutional buildings on the western side. Buildings in the Ramanujan IT park have a daily footfall of approximately 58,000 people. This only accounts for regular footfall and does not include additional diurnal migrating footfall. Institutions like NIFT or Anna University add to the variety and bring in a different set of demographic expected on site.The varying age group add to the safety and energy of the space and ensure use of the space at varying times of the day.

Located exactly adjacent to the Thiruvanmiyur MRTS station, this stretch of unused land has a great potential of becoming a community asset. Though easily connected and accessible near a foot over bridge, the current overgrown area is an urban void and becomes a unsafe zone in the night. Due to the stretch being neglected, the adjoining Buckingham canal stretch is also neglected and dumped with construction debris. The strip, shaded by the elevated tracks can become a new public space and add to the public realm of the adjoining area. Wild vegetation creates unsafe urban conditions

CURRENT STATE OF CANAL BETWEEN INDIRA NAGAR AND THIRUVAMIYUR The fact that the canal lies in a current state of neglect and deterioration is confirmed by the state of the canal between Indira Nagar and Thiruvanmiyur. The canal remains completely ignored by the people and authorities alike and continues to deteriorate day after day. The sides of the canal have illegal encroachments and slums that have come up over time. Due to these settlements, small sewage outlets are now draining untreated sewage into the canal making the stretch seem like a sewer. Larger storm water drains, mainly located near the two MRTS stations are directed into the canal and carry runoff from adjacent roads . Unconsciously dumped construction debris, carelessly disposed off plastic, unruly weeding are evident reasons for the deterioration of the canal in this stretch. Not only does all of this contribute to causing serious harm to the well-being of the canal, but it also poses major risk to human health and the environment as a whole.

With considerable changes taking place in the city for future development, a new underground metro station has been planned that will be constructed close to Thiruvanmiyur MRTS station This will make it more convenient and reliable for people traveling to the commercial hub near Thiruvanmiyur station . A new18 m wide canal road has also been planned to be constructed close to Buckingham canal which can further negatively impact the canal. While the road may help to ease out the current stress and make commute easier for the residents, it further threatens the canal.

GENERATING A COLLECTIVE VISION To better understand the site and generate a collective vision for Strip 1.0, we employed various media to conduct multiple surveys. A holistic survey for a stretch of 3.5 km was conducted by UDC that collected programmatic and demographic information. To build upon this information, The Blank Slate conducted social media surveys and installed survey booths at Thiruvanmiyur station in order to collect more specific information pertaining to our chosen site. To engage communities on both sides of the canal, the surveys were followed by a community participation workshop where residents were oriented and familiarized with possibilities on how the canal edge could be developed.

SURVEYS CONDUCTED BY URBAN DESIGN COLLECTIVE UDC conducted a survey to understand the communityâ&#x20AC;&#x2122;s aspirations for the site, their current understanding and programmatic needs. On 13th May 2018, a perception mapping walk was conducted along the 3.5 km demonstration stretch, i.e. from the Kotturpuram MRTS station till the Thiruvanmiyur MRTS station, for this survey. Participant citizens were asked to experience the stretch through their 5 senses and draw inferences. The survey questions were formatted in a way to collect demographic data about the residents as well. A total of 250 responses were collected and processed to understand the relationship of these residents and households to Buckingham Canal. The survey result showed that most citizens would want to see parks and nature trails along the canal with activities such as cycling to activate the same.

SURVEY CONDUCTED BY THE BLANK SLATE Conducting surveys is necessary to understand and learn more about a neighborhood, its surroundings and the citizens understanding of a cause. We employed various methods of surveying, such as online surveys via Survey Legend, Instagram polls, on site community participation survey and increased outreach using Facebook and Twitter. Involvement of the community in key to the success of creation of a design program. This was done keeping in mind barriers such as language and accessibility. The survey was conducted in both Tamil and English in order to involve every section of the society. The survey was visual in nature in order to connect with its participants. Accessibility to the survey was kept in mind and survey sheets were placed at Thiruvanmiyur station. A link for a digital format survey was also shared amongst the community groups through WhatsApp to increase outreach.

COMMUNITY PARTICIPATION WORKSHOP

KICKSTARTING RESILIENCE AT BUCKINGHAM CANAL

The community participation workshop was conducted in a three fold process. The first step was to orient the community with the short term action plan described in the next chapter. During the workshop, participants were presented with our design intent and methodology and were asked to respond to key concerns like safety, activities, aspirations etc. After the orientation presentation, the community was given an opportunity to express what they believe would be the ideal solution for the selected stretch. We also introduced a set of words which offered a frame work for the community to comprehend the parameters to be considered which served as a guideline for their expression. The workshop was welcomed by all and became a bare canvas for the expression of contrasting ideas with the wellbeing of the canal and the city. Some addressed the need for safety by suggesting to cordon of certain sectors of society while other encouraged the creation of an inclusive space and involvement of lower income groups. A few participants expressed the need for revenue generation through ticketed entries and a scanning process to ensure safety while some referred to safety as the wellbeing of ecology and suggested transforming the area near the canal into an eco park.

CONCLUSION The surveys were conducted keeping in mind the demographics of the user group to generate a collective vision and demonstrate potential design possibilities. The survey conducted by UDC and The Blank Slate used divergent paths where one used all the five senses to create an analysis where as the survey conducted by The Blank Slate used a visual stimuli to help the residents express their vision for the site. However, the surveys converged when they both showed highest votes in their programmatic studies for parks and gardens followed by cycling and nature trails. The initial survey conducted by UDC gave a holistic option of events and activities where as the survey conducted by The Blank Slate gave the residents an opportunity to specify their aspirations for events to be held in the space. In this category maximum set of votes were bagged by festival markets followed by food festivals and gardening activities. The surveys were followed by the community participation workshops which further detailed out the results received by the surveys and also introduced new factors to design such as safety,lighting,activities etc. This further shaped the design strategies to become more refined and user specific. The different form of surveys allowed us to collect data of a varied kind that added value and intensity to the approach. The survey helped us identify what the citizens of Chennai would envision as a program for the activation of the Buckingham canal banks. This also helped us acquaint ourselves with the priorities of the community. This involvement of the community not only made the design process more efficient but also gave the community a sense of belonging to the design and harnesses a sense of interest within the site. All in all the community participation workshop became the foundation for the programmatic study and the final proposal.

RATIONALE Through our project we intent to propose time based interventions that grow into the next intervention to reinforce and amplify the impacts of short term mini projects. We propose that revitalization of the canal edge begins with a short term action plan that aims at activating the chosen site through quick wins, create energy and dynamism and generate interest in the site within the communityâ&#x20AC;&#x2122;s heart and mind. The short term plan also aims at collecting much needed financial and social capital required for a permanent solution. The short term plan will engage the government

bodies associated with the site and draw their attention to the aspirations and the concerns of the users and equip them with data required for a massive canal restoration project. Through this multi step process, the short term plan builds the foundation for the actual long term vision.

ACTION PLAN

01 02 03 04 05 06

Create a new identity for the canal banks as public spaces. Encourage a diverse set of activities that involve all strata of the society. Revitalize existing unused urban spaces. Develop a bio diverse and native ecosystem to make the canal more resilient and sustainable. Enhance comfort and safety of the users through appropriate amenities, lighting and security. Increase community interaction with the site.

ACTIVATION BY PROGRAMMING

RESILIENCY PROJECTS

KICKSTARTING RESILIENCE AT BUCKINGHAM CANAL

OUR APPROACH The short term vision plan uses tactical urbanism to activate the site and to create interest in the community regarding the space. This interest further can be translated into efforts for the application of alternate water management system created and run by the community. The short vision plan creates an impetus for the growth of the long term vision

plan. The plan includes events and temporary functions allotted to the spaces that pull the community into the site. This further creates interest in the community which can translate into continuous community participation and stakeholder-ship in the execution of the long term vision plan.

WHAT IS TACTICAL URBANISM ?

"Tactical Urbanism is an approach to neighborhood building that uses short term, low cost and scalable interventions and policies to catalyze long term change." Tactical urbanism is a catalyst process that employs low cost, short term interventions to create a long term change. This approach not only offers local solutions for local design problems but also aims at realistic goals. Due to the scale of the intervention being small, the initial capital required for testing solutions is much smaller. as well and thus these projects can be implemented quickly.

WHY USE THIS APPROACH ?

Tactical urbanism helps draw attention of the citizens to the site.

Tactical urbanism helps foster public engagement with the site and the concerns of the site.

03 04

Brings the community together and creates a platform for the community to work together for the community.

The approach allows for room to test the feasibility of certain aspects of the long term plan.

PLACE-MAKING STRATEGIES Place-making strategies intend to integrate the social, cultural and physical fabric of the place along with the transformation of the space over time. The focus of the place making strategies is to integrate and capitalize on the communities aspirations with the assets of the design. These strategies aim at creating a space intimately connected to the people to demonstrate how their everyday spaces can be re-imagined. The place making effort can be categorized not only as a strategy but also become an integral part of the process of design .

MENU FOR PROGRAMMING The objective of the Menu for Programming is to create a set of place making elements that can be further employed to achieve certain set of goals that are aspired for any other strip. The menu consists of elements that could be used altogether or in permutations and combinations along various parts of the canal based on the demands of the space and its context. How each element activates a space and aids its growth as an urbanized area has been mentioned below:

Multiuse Pavilions

Community Gardens

Cafes

Multipurpose lawns are open patches of greens that can be used by the people as they wish to. The lawns not only function as a patch of landscape but also allow for a flexible space that can host an array of events.

Community gardens act as a ongoing activity that brings the community to nurture their work during a designated periods of time. It also functions as a nursery to grow native plants which can be later planted to restore ecological balance along the canal banks.

Cafes not only contribute to the social fabric of the place but also play an important role in the revenue generation required for the site. Cafes function as highly successful pull factors attracting large numbers of varied crowds to the site.

Gaming Zones

Social Gathering spaces

Green Infrastructure

Gaming areas add vibrancy and a sense of dynamism to the spaces. These areas attract all age groups equally and encourage socializing amongst the community. A dedicated space for the same allows for a meeting point for people of similar interests.

Dedicated social gathering spaces foster the communities sense of togetherness and allow for people to meet new people amongst the community. This creates a sense of belonging amongst the people and a connect is created with the space.

Bioswales and raingardens not only contribute to the ecological balance of the space by creating a home for native flora and fauna species but also help in controlling the floods and allow for sustainable growth of the area. These elements also add to the landscape of the area.

Buckingham Canal, from the Thiruvanmiyur MRTS station, 2019 The Blank Slate | Eyes On The Canal

BUILDING RESILIENCE THROUGH SCALABLE INTERIM PROJECTS INTRODUCTION Chennai has been facing drastic climatic changes subtly over a long period of time and in smaller more stronger spurts on occasions like the 2005 floods and the 2017 floods. The canal has been the pillar of resilience for the city. However, The canal is in a current state of neglect and deterioration. One of the sources of pollution in the canal is urban run off from roads and urban spaces. The OMR so closely located to the canal has run offs that include metals and chemicals associated with road transport. The open area located along banks has become a free grazing ground for cattle because of which the fecal matter of the grazing animals is also a big part of the run off. Chennai also discards 60% of its untreated sewage waste into the canal. Through the length of the canal many sewage outlets have been mis connected into the storm water drains adding to the sedimentation issue.

Green infrastructure incorporates both the natural environment and engineered systems to provide clean water, conserve ecosystem values and functions, and provide a wide array of benefits to people and wildlife. The term green infrastructure means planting trees and restoring wetlands, rather than building a costly new water treatment plant. It means choosing water efficiency instead of building a new water supply dam. Various activities can be housed and created around the GI elements. The GI elements can also be created with the participation of the community themselves. Many educational and institutional activities can be planned around the GI elements. The GI elements add to the landscape of the site situated around the cafes and other activity zones. These elements other than adding to the ecological balance of the space also become centres for activities. GI is economically friendly , efficient and improves the quality of life. We have designed a series of test projects to demonstrate alternative water management techniques, integrated as landscape elements in the design.The pilot projects aim at creating a set of green infrastructure initiatives that when put together will form a strong and unified system for water management.

These and many such pollutants become a part of the sedimentation in the canal. The canal also faces problems like silting, weeding, collection of non biodegradable substances, storm water run offs and sewage collection, human and animal excreta in addition to the sedimentation problem. In order to clean the canal water and rejuvenate the canal all these concerns pose as the immediate challenges. We propose to use a low cost low maintenance sustainable system which acts within a smaller timeline and budget as compared to laying out and maintaining a sewage treatment plan. A sustainable sewage treatment plant employs biological solutions and systems to counter the above problems.

BAIMA CANAL RESTORER LOCATION The Baima canal restorer by Todd Ecological in China is a case of ecological engineering in combination with the creation of a public amenity. The city emptied its commercial wastewater and sewage into an 80 km network of canals before emptying it into a nearby river. A 600-meter canal named Baima, considered one of the worst in the city, had extreme problems with odor and floating solids created by the influx of thousands of gallons per day of untreated domestic sewage. A Restorer on the Baima canal consisting of 12,000 plants composed of 20 native species was planted in the canal. Constructed with a walkway down the center, the Restorer has met water quality goals and created a prized recreation area for the members of the community. The Restorer was able to reduce odors, eliminate floating solids, and drastically improve the aesthetics of the neighborhood. The clarity of the water in the canal increased from less than 6 inches to several feet, while meeting several secondary effluent standards.

NEKNAMPUR LAKE , HYDERABAD The 3,500 sq ft Floating Treatment wetland has been designed using STYROFOAM, BAMBOO, GUNNY BAGS, COIR etc. This floating island is MULTI-LAYERED and installed close to the inlet of the lake. When the water passes through all the layers, it gets filtered, eventually resulting in optimum fresh water. This combination used is MOSQUITO REPELLENT while also helping in the cleaning of water and INCREASING THE BIODIVERSITY of the lake.

HEBBAGODI LAKE , BENGALURU The 12,000-sq ft island has strips of vegetation that crisscross the waterbody. Floating rafts are built with REUSED PVC PIPES making use of the HYDROPHONICAL

PLANTS. SILT-REMOVING and DEWEEDING OPERATIONS were taken up on a war footing. ENERGY-EFFICIENT CASCADING AERATORS were installed to increase the level of dissolved oxygen in in water.

UNDERGROUND CONDUITS were laid to address

sewage spills and stench.

KAIKONDRAHALLI LAKE , BENGALURU The base of the Floating Treatment Wetland was created using PVC PIPES AND DISCARDED PLASTIC BOTTLES, NETTING , A NYLON MESH, and TAGS. The idea behind the construction of this FTW was to Reduce EUTROPHICATION (the depletion of oxygen in a water body due to excessive nutrient accumulation, which kills aquatic animals), improve the landscape of urban lakes, and PRESERVE their shores through wave absorption.

POISAR RIVER , MUMBAI The base of the FTW is made using 500 DISCARDED PLASTIC BOTTLES which were tied together to create a makeshift ‘mop’. The plants in the wetland provide a PECULIAR HABITAT

FOR BENEFICIAL MICRO-ORGANISMS IN THE ROOT-ZONE (which also pump oxygen from the atmosphere into the bed) and jointly PURIFY THE SEWAGE while the plants are automatically nurtured by the nitrogen and phosphorous in the sewage.

INTEGRATED WATER MANAGEMENT The proposed Integrated water management system for restoring Buckingham canal includes creating a network of small scale green infrastructure projects. A raingarden, bioswale, a strip of constructed wetlands on either banks and a system of floating treatment wetlands and aerators have been used to begin the process of restoring the canal edge at Strip 1.0. These elements could be created with the help of community following a detailed framework for the execution and planning of GI elements which will foster a

sense of ownership in the community. GI elements not only aid in storage and assimilation of storm water but will also purify the water during its passage through them. GI elements not only help with water management but also create a healthier environment for the community. These have been designed to restore ecological balance by providing habitat to various species of animals, insects and birds.

INTEGRATED WATER MANAGEMENT:CANAL REJUVENATION The proposed canal rejuvenation treatment system works on the biological process of Phytoremediation. The term “Phytoremediation Technique” encompasses the life interactions of bacteria, the roots of the wetland plants, soil, air, sun and water. Phytoremediation is the direct use of living plants for in situ remediation of contaminated soil, sludge, sediments, and ground water through contaminant removal, degradation, or containment. This technique is mainly solar energy driven and passive and can be used alone or in combination with mechanical methods. The following are some elements and steps used in the proposed system:

Cleaning of the canal De-silting and dredging of the canal is required to begin the rejuvenation process. In order to clean the existing water in the canal dredging and desilting become the two major tasks to be undertaken. The depth of the canal must also be altered to change the direction of flow within the canal. Changing the flow of the canal The first step is to change the flow of the canal from to upstream to downstream. If the flow is altered the water will flow into the canal from Adyar river which would lead to an increase in 1’ to 2’ water level rise. Use of check damns Check dams must be used through the length of the canal. Choir checks dams can be employed in order to create divisions in the canal to counter solid waste and sedimentation. The check damns also aid in control and maintenance of the canal. The check damns also help in damage control by controlling the flow of the water flowing through the canal. Check damns also reduce the water flow speed and and reduce the particle content of the canal water. Aerators Three types of aerators must be employed on the canal surface namely jet aerators, manthan aerators and nano aerators. Phosphates compounds present in domestic sewage can be changed to alternate phosphate compounds using nano aerators. On the other hand jet aerators serve a purely aesthetic purpose on the canal surface. Manthan aerators are surface aerators that resolve water gorgolation by mixing the solids present in the water dissolved and bring it to the top Floating treatment island Floating treatment islands not only add to the beautification of the site but also clean the water upto 80%. Plant roots used in the floating treatment islands introduce bacteria into the water that change the chemical composition of the water. The ammonia and the sulphate content of the water, which is the major cause for the smelling of the canal, are broken down and the smell is reduced. Constructed wetlands The constructed wetlands help in cleaning of the sewage content in the water. The run off water from the footpath end to the canal retention wall and is let in through the inlets of the constructed wetlands. This method directly treats the sewage water and counters smell and color at the source. Vertical green wall The retention wall for the canal can be planted with specific plants to purify the water of the canal. Micro plastics Microplastics dont dissolve in the water and the particles are very small. The nitrate oxide content is converted to aluminum nitrate by plants which further fosters the aquatic life of the canal.

They are typically sized to treat the water quality event, also known as the “first flush,”which is the first and often most polluted volume of water resulting from a storm event. The water run off from the service road can be directed into the Bioswale, post which , the water will percolate through the layers and get purified. Some of which will be directed towards the canal by a pipe and the rest will enrich the ground water level. The proposed Bioswales covered an area of 9 square meters. ie. 1.5m x 6.0m respectively.

DESIGN CONSIDERATIONS

1. Bioswales require appropriate media composition for soil construction. The engineered soil mixture will consist 5% maximum clay content.The side slopes are 4:1, with a maximum slope of 3:1. 2. In order to protect adjacent subsurface infrastructure we have maintained minimum clearances. We will install waterproof liners as separation barriers. 3. The Bioswales are designed to maintain a 5-foot minimum clearance from the bottom of the bioswale to high groundwater table. 4. The overflow/bypass drain system has been raised approximately 6 inches above the soil surface to manage storms larger than the water quality event. 5. The overflow/bypass drain system has been raised approximately 6 inches above the soil surface to manage storms larger than the water quality event. 6. Runoff that enters the bioswale in a sheetflow fashion requires that the edge of the bioswale be flush with grade. Where curbs are necessary, intermittently space curb cuts to allow runoff to enter and be treated within the swale. 7. Bioswales are composed of diverse, native vegetation. Vegetation selection considers species compatibility, minimum irrigation requirements, and the potential for wildlife habitat creation. 8. Discourage pedestrian trampling by using low curbs or barriers, or hardy vegetative ground covers.

INTEGRATED WATER MANAGEMENT : INTERIM PROJECT NO 03 RAINGARDENS IN THE CENTRE OF THE SITE

A rain garden is a garden of native shrubs, perennials,and flowers planted in a small depression, which is generally formed on a natural slope. It is designed to temporarily hold and soak in rain water runoff that flows from roofs, driveways, patios or lawns. The Raingardens cover an area of 100-150 square meters. Water logging within the site can easily be curbed by the creation of a Raingarden in the middle of the Strip. The water runoff from the nearing areas can be directed into the Raingarden by providing a gradual slope. The water will then percolate through the root system of the native plants and layers of soil, getting purified. Eventually it will seep down to recharge the ground water level while taking care of the issue of water logging in its vicinity.

COMMUNITY PARTICIPATION MONITORING AND CONTROL EVENTS AND ACTIVITIES

The green infrastructure elements integrate into the public spaces. Curated events specific to them can be organized in order to bring focus and eyes on the canal to ensure the well being and rejuvenation process of the canal. Some examples are: »» Sapling Plantation Monday »» Build An Island Tuesday »» Canal Day »» Restoration Celebration Day

DEVELOPING AND MAINTAINING GREEN INFRASTRUCTURE It is important for the community to be involved in the creation of GI elements. It not only induces a sense of pride withing them but also builds a sensitivity and a sense of ownership towards the elements. This can easily be taken up as a scheduled recreational activity or a leisure task for the citizens. Working to build GI elements is not only helpful to the nature and the Strip but can also be proved to be therapeutic in nature for the people participating in the activity. Listed below are some basic way that the community can be involved. Apart from which, there is also a sample module or week wise schedule that can be employed for the same. Community participation for the creation of GI elements: 1. Designing the various GI elements and selecting an appropriate site for the same. 2. Sizing and planning the GI elements. 3. Selecting appropriate plants for the site. 4. Spreading awareness and attracting the community to the site. 5. Rain garden and Floating Treatment Island construction and planting. 6. Maintenance and control.

TIMELINE FOR MAINTENANCE AND CONTROL The following timeline shows the necessary steps and concerns the community must keep in mind in order to ensure proper maintenance and control of the interim projects. The following is a sample timeline which gives a frame work and highlights the key concerns that might surface over a period of time. The timeline has parameters keeping in mind the aging and wear and tear of elements with time.

FORMATION OF FRIENDS OF THE CANAL Mission statement for Friends Of The Canal: The initiative for formation of the Friends of the Canal it with a singular mission of recreating the character of the canal. This entails the water quality, the edge conditions and the interaction of the banks with the neighboring communities. This initiative will subsequently enhance the real estate costs, will add identity to the space and foster a safe environment. The friends of the canal can become the sole agency directly working with the government agencies to improve the quality of the the canal and can include professionals and active community members. Funded by the community themselves and backed by financial aids coming in from various sources such as MNCs, government bodies and other forms of donation, they can become a mediator between the government and rest of the city.

Treasurer

The treasure functions as a neutral party and overlooks the financial aspects of the short term vision plan. The reception of the capital along with allotted distribution becomes a major part of the role played by a treasurer. Some of the smaller roles played by the treasurer are as an advisory and overlooker of the financial activities of the remaining teams.

The design team is further divided into the designing team, the design execution team and the design evaluation team. This team is solely in charge of all things to do with design from conceptualizations to designing to material selection to evaluation of the space created.

The logistics head as the name suggests is in charge of the logistical requirements of the short term plan. Providing materials, timely delivery of material, smooth functioning of the site functions, external event management are a few roles to be played by the logistics head.

KICKSTARTING RESILIENCE AT BUCKINGHAM CANAL

ROLE OF THE FRIENDS OF THE CANAL: Creating Brand Partnerships : Friends of the Canal can work with bigger brands to Ramanujan IT park and institutions like the NIFT who can provide financial aids and form brand partnerships to generate social and financial capital. Design elements can be employed to achieve the goals of the partner.

Establishing a management board : The friends of the canal initiative is a non profit initiative to rejuvenate the canal. The goals can be set on a timeline and cross checked periodically. The budgets and funding will be decided by the management and companies and partners with visions in alignment with that of the Buckingham canal can participate with the same.

Involving institutions for Educational Partnerships : Friends of the canal can offer educational programs to the neighboring institutions including schools and colleges alike. Students from the neighborhood can participate in educational programs that add to the betterment of the site as well as the ecological welfare of the site. The students could explore art festivals,festivals, park designs and public art. This initiative would also give an opportunity to the students to interact with professionals and specialists who could also share real life applications with the students.

Forming Partnerships with NGO's and Institutes Neighborhood gardening can be encouraged as a activity with involvement of local groups like UDC, IIT group - extracurricular, local group, school children and volunteers. Friends of the canal can partner with special volunteering organizations such as SayTrees , Nizhal , Hand in Hand , and Plant a tree in India that can organize drives for tree plantations. Similarly there are organizations dealing with water like Environmentalist Foundation Of India (EFI) , ExNoRa International , regreen Chennai that engage themselves in volunteering for Water Conservation and cleaning.

Collection and safe keeping of Monetary resources : Fund collection through renting out the space, crowd funding for events, getting in touch with the MNCâ&#x20AC;&#x2122;s and local markets.

The initiatives discussed above to activate the canal bank holistically aim at demonstrating alternate water management techniques while activating a public space. Keeping this goal in mind our efforts are directed towards creating a program that can be run by the community and for the community. This approach ensures that the canal banks are being taken care of and maintained by the users themselves and eliminates any third party. The community involvement also ensures local knowledge and sense of belonging is fostered. Within the much larger community of the city we suggest the creation of a smaller set of individuals to be held responsible for the tasks designated to them.

INITIAL CAPITAL INVESTMENT The diagrams below draw the relationship between the capital that is required to execute the activation process and the capital that can be generated to further the process of activation of the canal bank. The funding for the maintenance and rejuvenation of the canal and its water management can be extracted from the canal banks itself by creating a public space on one hand and generating alternate water management techniques on the other. This kind of a revenue then allows the community and the governing bodies to further the potential of the site and most importantly the canal itself.

The project requires funds of varied sizes ranging from Rs. 70,000 to an higher limit of Rs. 9,50,000 to build the various elements required for the intervention. This leads to a sum total of Rs. 31,10,000 that needs to be invested into the project for its wholsesome completion. However, 77 % of the capital that can be generated merely by the rent received for these cafes. Going ahead concerts, stalls, games area etc would all bring in funds. The profit that is generated from the intervention is approximately 11 times the capital invested in just one year. This becomes an on going strategy that generates fund for the care taking and rejuvenation of the canal. These funds are calculated keeping in mind a time frame of just a year however with passing time and renewed interest in the canal these funds could increase leading to a renewed Buckingham Canal edge.

Funds are needed to develop activities and create stress free spaces in the cities for the public recreation. For tactical urbanism, funds are aimed at benefiting the crowd who plan to develop short term activities with long term gains. Following are the channels through which one can receive funds for projects evolving around Tactical Urbanism.

SPONSORSHIPS Probable partners All corporations and shops in the vicinity could be a part of fund collection with some add-on benefits provided to the partners. For MNCâ&#x20AC;&#x2122;s with a heavy footfall , parks and plazas could be created in our site that could act as a chill out space for the staff.

GOVERNMENT INVESTMENT Funding from Government agencies Local Governing Bodies like the PWD or Chennai Metro who govern the land in the area could help the organization with developing and raising funds for activities that help the community grow. Organizers could have a session wherein the head of the local governing body could act as the head of the activity and promote tactical urbanism. Local Corporators/Politicians who are in charge of the area could also help in funding and help citizens activate the space.

CAPITAL CREATED AGAINST SERVICE Events and Markets Weekly bazaars and events could help the organizers generate revenue for developing the area and having drives that involve the community. An application could be created with updates and registrations for people to get interested in the events and marketing activities.

INCENTIVE BASED CAPITAL Event Organizer Communities who plan on continuing with activity building on site should try and generate revenue through renting spaces for small events or through activities that involve paid entries for flea markets, yoga classes, dance classes etc. They can look out for and gain funds through activities such as pet shows, art classes, outdoor fitness activity sessions that are short term projects generating good amount of revenue.

DONATION BASED MODEL

Crowd funding Crowd funding generally takes place in four forms ie. Donation, Rewards, Debt, Equity. Event Organizers could pull in strategies to gain funds through mainly two forms of sourcing â&#x20AC;&#x201C; Donation and rewards. They could opt for creating websites to gain donations through domains such as: Kickstarter, Indiegogo, RocketHub, Gofundme, etc. For reward based crowd sourcing, organizers could pull in strategies like marathons, walkathons, etc. that could be a public event with heavy amounts of crowd funding.

DESIGN EVALUATION CRITERIA The approach selected must be analyzed upon completion in order to the find the most appropriate way forward. The evaluation of The Strip 1.0 enables one to then modify and alter in order to develop the design solution for the rest of the public space. The evaluation process can be carried out by community participation workshops, observations and data collection methods like recording and public forum discussions. This can also be reinforced by social media analysis, footfall calculations and people behavior studies that further more detail out the concerns and design victories to shed light onto the best way forward.

A Vision for an Interconnected Public Space Network From The Strip 1.0 to a 10 Km long Public Strip

Chennai has the least open space amongst the major metro cities in India. The city has only 2.09% of open spaces that translates to a 0.81 sq. m open space per capita. The Strip intends to create a green patch running along the offering green open spaces to all the communities it passes through. The new public space would offer the residents of Chennai renewed public recreational amenities and much needed open space.

The Strip can transform the land below Chennaiâ&#x20AC;&#x2122;s MRTS into a A new vibrant public space that contributes to the fabric of Chennai physically, ecologically and culturally out of an otherwise under used urban pocket.

The initiative can bring about a great shift in the lifestyle amenities offered to the people allowing for a healthier and fitter lifestyle. The Strip will also enhance pedestrian connectivity in the city that currently struggles with great challenges to the transport systems traffic and strikingly low footfall in the MRTS. The green infrastructure suggested in the program will add to the current infrastructure available for storm water drain and sewage treatment and reinforce it further making it a solid system taking away the mesh like character with numerous loopholes. The space will offer the people a water front in the long run which can add greatly to the fabric and character of the adjoining neighborhoods. The long term vision plan looks forward and envisions what Buckingham canal and its bank have the potential to become over a period of time. The Strip 1.0 is a fountainhead for activation for a new network of interconnected public spaces. The larger goal of the vision is to create the much needed public space for Chennai, enhance environmental and ecological sustainability and encourage active lifestyle by aiding pedestrian thoroughfare. With these goals in mind design strategies have been recommended for the new public Strip to create a public space that will cater to people of all financial and physical abilities, a universally inclusive environment that encourages a diverse, active and healthy population. Community participation, ideas and improvements from the short term action plan and on going betterment of the canal can become the pillars for this long term vision. The extended duration of the long term vision becomes a great opportunity for resources of every kind such as financial, design based, social capital to be bought together to create a set of resources that will be capable of bringing about great change.

The park must have ground markings to give designated spaces to children, senior citizens and differently-abled residents. Designated spaces must be dedicated to weaker sections of the society in order to ensure smooth, safe and comfortable use of the space. The community garden must be a combination of softscape and hardscape to promote connection of the users to the natural terrain. Exposure to natural terrain ensures better fitness and activity levels amongst children and adults alike. In order to ensure activity in the space throughout the day, lights must be installed along various circulation spaces and activity zones so that spaces feel safer.

2.0 PUBLIC PLAZA

Objective

KICKSTARTING RESILIENCE AT BUCKINGHAM CANAL

Creating public spaces such as plazas and pavilions Plazas and pavilions create very effective public spaces and also add to the accessibility for pedestrians and bicyclists. This space can be used as a multiuse area to house various events and activities. On not very busy days this space can also contribute to the public realm as breathing spaces and pause points.

Strategies JJ

Create attractive plaza spaces that are well maintained. The Public space must feature landscape elements, amenities like drinking water and public toilets and fixed and movable seating. The public plazas must be placed near pedestrian ways in order to increase footfall. Instead of have one large plazas the plaza could be broken into various smaller plazas and squares. Placing public spaces near transit stops will also ensure greater footfall and add to the transit public infrastructure. Plazas must be accessible to bicycles to encourage activities and accessibility The plazas must include sidewalks and other existing pedestrian walkways. By creating a leveled area adjoining the sidewalks, plazas can ensure visibility and safely connect the plaza to the street. This also makes the plazas more accessible to the differently abled. The plazas should house a diverse set of functions and be used for events and activities. The plaza must be designed to be weather proof.

PROTECT CRITICAL INDUSTRIAL AND CITY INFRASTRUCTURE

Karamjor port

A Toolkit Of Water Sensitive Intervention

Our proposal is to re-imagine the Buckingham Canal as a means of making the city of Chennai climate proof by taking pro-active and collaborative steps that are urgently needed to address the challenges arising out of unpredictable climate, rising sea levels, future storm surges and possible inundation of the coastal areas of Chennai.

CITY LEVEL INTERVENTION

Limit Urbanization

Otteri Nala

Manali petrochemical ltd

STRATEGIES: • Absolute stop to illegal fly-ash dumping in the canal • Promote wastewater and sewage reuse in industries • Heavy investment in flood proofing critical infrastructure • Extensive purification and dredging of canal

The proposal offers a series of strategies and a kit of interventions that are to be applied based on the existing local conditions instead of an over-arching broad master plan. Rather, through the use of macro, local and community strategies we propose various interventions that can be understood in themselves or applied as a comprehensive landscape & urban strategy.

Berm

Ennore Thermal power plant

NORTH CHENNAI This zone houses Chennai’s critical infrastructure and industries that keep it running. Almost all of Chennai’s power plants, water treatment facilities, industries, dumping yards, water supply and ports are located here. With sea levels rising in the coming decades, unless steps are taken to protect critical infrastructure now, Chennai will come to a stand still.

The proposal broadly looks at the different industrial, residential and ecological landscapes that the canal runs through in Chennai and based on land use suggests strategies to combat the perils of climate change at a regional level including Protecting Critical Infrastructure, Flood proofing Vulnerable communities and Planned water sensitive future development. If maintained well, desilted and widened Buckingham canal has tremendous potential to protect Chennai from excessive flooding. The project studies future shocks and stresses that could affect the city and identifies Buckingham Canal as an asset that has been providing resilience and is need of strengthening to future-proof Chennai.

At a local scale, we look at three frames - At Adyar River, a Residential and an Institutional frame and suggest how a co-hesive approach of developing the canal and surrounding area can help protect the vulnerable low lying coastal area. The canal is revitalized on the strategy of ‘Delay, retain, store and reuse, drain when necessary’ approach. There is a toolbox of physical measures that have been illustrated below; these display the water sensitive intervention measures that respond to the varying challenges arising in the three frames selected along the canal. Proposed strategies like natural berms and planted mangroves along Adyar river to neighborhood level constructed wetlands for local Sewage treatment, biofilteration islands in the canal, retention ponds and flood proof public spaces capable of transforming into storage areas strive to create a refined balance maximizing the closing of local water cycles and optimizing two flows of public money into one integral investment. Along with water sensitive strategies, we propose land use regulations,such as increasing FSI in higher lying areas to help shifting of vulnerable communities as well as building guidelines with which we can begin to mitigate and protect communities of Chennai. By integrating Chennai’s different urban layers and land-uses, this proposal enhances and broadens the relevance of the historical and social values present there, and at the same time raising the quality and attractiveness of the canal by converting it into an adaptive waterfront development. The innovative and inclusive urban solutions offered here convert a current liability for the city to which it has turned its back on into a social asset which not only protects the ecology, but honors the cultural traditions, local identity and also enhances the economic returns for the city, thereby providing a comprehensive resilience from nature and man induced challenges of the future.

FLOOD PROOF VULNERABLE COMMUNITIES AND INSTITUTIONS

No Infrastructural Waste STRATEGIES:

A berm wall will help in blocking the water from overflowing into the city during a period of floods or disaster.

By limiting urbanization the green spaces are retained and they help in controlling the climate.

Construction Wetlands

Waste Water Treatment Plant

A berm wall will help in blocking the water from overflowing in the city during a period of floods or disaster.

This Plant can help convert waste water from industries and residential area to an effluent that can be returned to the cycle .

Expansion Of Flood Area

Helophytes

By provision of proper management for disposal of heavy infrastructural waste, the water bodies are avoided from being polluted.

Reduction of Paved Areas

Reduced Pavement will help in reduction of surface water runoff . Thus there will be a lower risk of flood.

• Create Neighborhood level flood defense plans • Build decentralized natural wastewater treatment systems such as constructed wastelands • Soft flood protection edges along rivers • Develop micro water management solutions for informal settlements • Develop building regulations for construction in flood prone areas • Increase FSI in high lying areas to promote sparsification from vulnerable neighborhoods • Constant biofilteration in canal • Rethink flood infrastructure as social infrastructure

Vegetation on streetscapes reduces the impact of heat island effect while providing shade as well as creating public parks .

Employing water as a functional aspect to heritage or prominent buildings helps in creating awareness.

Rain gardens are a garden of native shrubs and perennials that are planted in a small depression. They will temporarily hold and soak water from roofs and roads.

Bioswales

Floating Filtration Islands

Water Squares

Sewage Treatment Plant Sewer Outfall Water Treatment Plant

Bioswales are a depression that retain water from roof and streets. This way clean water is infiltrated into soil.

Floating filtration island help in up taking nutrients in aquatic systems making them unavailable for algae or aquatic weeds.

Water Squares are a combination of water storage with an improvement of the quality of urban spaces. It also gives an identity to spaces in the city.

Raising The Ground Water Level

Natural filters

Raising The Ground Floor Level

Porous Pavements are created with a range of sustainable materials that allow movement of water through the surface.

These filters help in trapping waste from water and help improving the quality of water.

Constructing buildings on stilts will help in preventing flooding in buildings .

Use of Ground Cover and Shrubbery

Rainwater collected from roofs and man-made hard surface would help in storing water for the dry periods .

Green roofing systems will cater to solving problems like temperature increase and reduced habitat.

Perungudi, Under-served areas with proper sewage treatment facilities

SOUTH CHENNAI The southern section of the canal transects a relatively lesser developed area of Chennai providing opportunities to develop efficient decentralized water management systems and self reliant communities on the east of the canal as well as flood-proofing the IT hub on the west. Neighborhoods such as Sholinganallurmain that currently discharge sewage directly into the canal can benefit from micro strategies. STRATEGIES: • Develop water management toolkit specifically for aquifer zone • Decentralized sewage treatment systems for under-served areas • Ensure areas South of Chennai do not get affected by polluted waters flowing in the Buckingham Canal due to the city’s inefficient water management. • Protect and restore Pallikaranai marshlands • Encourage IT sector to invest in private water management

A flood protection berm at the canal where it meets Adyar river will help in keeping the water out of the city while providing a vertical protection from future storm surge and rising sea levels. The Berm also offers pleasant, accessible routes into the park, with many programmed spots for resting, socializing, and enjoying views of the park and river. The berm is planted with a dense vegetation and mangroves for ecological protection. The filtration zone at the mouth of the canal constantly purifies the water as it flows down from an industrial zone. The Frame also demonstrates how relocation zones in higher lying areas can clear the encroachments near the canal and provide needed land for its widening. Cycling networks connect the landscaped berm with the canal.

Residential areas can be retrofitted with water resilient infrastructure and strive to close water cycles. Bioswales on most frequently flooded roads, retention ponds, water squares which store water during rainfall along with micro rainwater harvesting and on-site sewage treatment help reduce the load on Chennai’s overworked treatment plants. Boardwalk and Bike-way increase connectivity and provide residents with access to the canal which emerges as a new public space. A retrofitted station plaza with green roof strives to reduce the damage done to the canal due to the construction of the Metro and provides space for relaxing, socializing and helps reduce runoff.

Institutions with large chunks of unbuilt land can densify to create room for new development on high grounds. Constructed Wetlands on vacant government and institutional lands can begin to treat sewage currently being dumped into the Buckingham Canal. By increasing FSI in this area space can be generated for rehabilitation of vulnerable communities affected by floods. Public gardens, rain gardens etc need to be built to cater to increased projected densities and provide permeable areas. Land needs to be reserved for affordable housing on high lying lands to protect the needs of low income communities in the future.
