TOWARDS INCLUSIVE CITIES Local Area Plan for urban transformation
Ambawadi, Ahmedabad
ANUKRATI SHARMA PG 190151 Urban Transformation Studio | CEPT University
STUDIO BRIEF UT4002- Urban Transformation Studio Studio Tutor : Purvi Bhatt Teaching Associate : Nishi Shah This studio will focus on the design aspects of urban transformations within the existing urban areas. The underlying context is that Indian cities are growing rapidly in terms of population and therefore expanding physically. Increasing urban population and the growing urban incomes will fuel demand for more and more built-floor space in cities accompanied by a demand for infrastructure. Many urban areas within these cities are dealing with unsustainable levels of stress on infrastructure, resources and public services and are becoming increasingly unliveable. As an attempt to address these concerns, the Ministry of Housing and Urban Affairs (MoUHA) has initiated various schemes such as AMRUT (Atal Mission for Rejuvenation and Urban Transformation), SMART CITIES MISSION and HRIDAY (Heritage City Development and Augmentation). These schemes enable planning for developing infrastructure in the brownfield areas through mechanisms such as Local Area Plans (LAP) and Town Planning schemes (TPS). These typically include those parts of the city that area already developed but are not able to sustain the pressure of existing infrastructure. Students will work on the projects that are emerging out of these initiatives defined by their studio tutors. Through their design projects, students will explore the methods of integration of the physical design with the regulatory frameworks (TPS, LAP) in creating liveable, functional, memorable, safe and sustainable urban areas. The projects will have a strong design focus on the physical setting, however issues of private ownership and social equity, land economics, planning models, project finance, and implementation strategies will also be addressed. The learning outcome of the studio will be to: 1. 2. 3. 4. 5.
Prepare strategic framework plan of delineated areas with identified design projects Detail design of the identified urban design projects Prepare building regulations for the intended urban form outcome for the project areas Prepare a planning model for executing the proposed framework plan and carrying out various public place design project Prepare Detailed Project Report to communicate effectively all the aspects of the project

LAP FRAMEWORK- CONTEXT
Credit: LAP for transitillustrated handbook
LAP handbook for Indian cities claims that the population growth rates for urban India show that by 2050 about 814 million people will live in urban places. With the increase in rate of influx of urban population, cities are experiencing rapid expansion, especially at periphery leading to unmanageable problems. In the face of these challenges, LAP around transit has been utilized to reform conventional planning practices to move towards more liveable and sustainable cities through improving development around public transits. LAP DEFINITION: LAP is a planning instrument to integrate city-level mobility and infrastructure development envisioned in a development plan, with neighbourhood level accessibility and area-level improvement either through natural process of urban renewal or through planned redevelopment.

TOD DEFINITION: To create a dense, diverse and accessible urban fabric to enhance, encourage and induce commuter populations to use public transit as their preferred mode of getting around and also support non-motorized transit. Credit: LAP for transitillustrated handbook

SITE PARAMETERS ASSESSMENT The chapter elaborates on understanding the site, and exploring the current situation to create a foundation for creating LAP framework for the site.
1.1 Assessment- Site and context
Map 1: LAP Areas
The comprehensive Development Plan 2021 of Ahmedabad focuses on compact, sustainable development through establishing LAP under TOD development. The zone is established along 200 m on both sides of transit corridors (Metro and BRTS) with the intention to densify the area, increase the use of public transport and to promote dense, mixed-use development. To increase the density along TOD corridors, the zones are allowed to achieve up to 4 FSI. As per AUDA, the characteristics of TOZ are: 01. Walkable development within 5 min (400 m)- 10 min (800 m) 02. High density development 03. Mixed uses 04. Improved street network connectivity and walkable block size 05. Pedestrian friendly street environment 06. Efficient use of ground 07. Inter-modal connectivity 08. Efficient infrastructure 09. Seamless integration of public and private realm 10. Parking management (on and off street) 01

1.1 Assessment - Site and context Ambawadi developed as a residential precinct and further development of major institutes became a significant mark in Ahmedabad’s history still defining the character of precinct. Introduction of TP schemes in 1976 led to regulated development. In 2006, BRTS construction led to an increase in housing demand. The TOZ development was introduced to modulate the density which has shaped the current built environment.

URBAN TRANSFORMATION STUDIO
One of the key characteristic of the studied site is presence of various educational institutes which take over large parcels of land in the center of the city. When the city of Ahmedabad started expanding towards the western side of Sabarmati river, the development anchors were actually large parcels of land which gave rise to these institutional development, thus contributing to the western development of the city. But today these institutions have become inert which remain as gated precincts with large unwalkable blocks and large parcels of land which are underutilized. The institutes don’t interact with surrounding communities and become isolated islands resulting into fragmented urban structures.

The area is located on 120 Ft Ring road, withn TOD zone impacted by 2 BRTS corridors. Moreover, East-West Metro route runs along northern edge and North-South Metro route along southern edge, situating the area in center of rapid development with increased FSI. The area is defined by presence of various educational institutes, with commerce six metro and shreyash metro as closest metro stops. The BRT route runs along 120 ft. Ring road, crossing railway line through Shreyash flyover. The built character is primarily defined by low rise bungalows, with few high rises (14-15 floors)coming along the BRTS route, as per 70 m height allowed on ROW > 36 m.

URBAN TRANSFORMATION STUDIO
Low walkability due to large block sizes with multiple dead ends The site currently has only about 13% of area under streets, which constitutes the BRT corridor majorly. And the internal roads of the site are not interconnected, hence creating multiple dead ends resulting in less permeability, poor connectivity and large block sizes. Most of the existing block sizes do not fall under the walkable perimeter range, owing to the presence of institutes and gated housing societies. Low accessibility due to lack of integration between BRTS and AMTS
No designated crossing for BRTS and AMTS stops
In case of transit connectivity, individual network and coverage areas of both the public transport systems are sufficient, but there is a lack of integration between these two networks, as well as to other para transit modes leading to inter- connectivity issues. SPRING 2021

The poor condition of street infrastructure can be observed along the entire BRT corridor stretch, and in various cases, internal networks as well. This adds up to the unwalkable blocks already present within the site, making the experience for pedestrians and other users unpleasant and unsafe.
URBAN TRANSFORMATION STUDIO
Lack of permeability along BRTS While the street character differs along the BRTS corridor, there are few parameters that consistently create hindrance in walkability and disrupt the user’s experience.
1- Disconnected Institutional edges, Insufficient pedestrian walkway.
Common factors are: 1. Opaque and inactive street edges due to continuous boundary walls.
2- Improper delineation of public and private land
2. Improper delineation of public and private spaces resulting into encroachment
3- Space under flyover being used for disorganized parking & vending
3. Disorganized parking 4. Unregulated informal vending 5. Insufficient walkways and lack of other required street furniture and public amenities.

1.2 Assessment- Existing analysis BUILT ENVIRONMENT
Heterogeneous land use The area falls under private ownership primarily, creating an easier pitch for redevelopment. The 40% land under public institutions provide an unique opportunity to efficeintly utilize the same for public use. The job centers in the form of commercial developments concentrate near major junctions and public transit station leading to heterogeneous land use within the precinct.

Low rise built form The TOZ area is primarily characterized by residential use. It consists of various housing typologies, with detached housing being most dominant, poorly consuming the benefit of the TOZ area. Most of the housing stock is about 30 years old, indicating potential for redevelopment. The slums located at heart of the site present unique challenge as the surrounding area redevelops.

1.2 Assessment- Existing analysis Underutilized FSI The low rise built form on the site poorly utilizes the available 4 FSI. The density matrix analyzes achievable FSI for every plot as per current GDCR. Major observations are: 1. for smaller plots, prescribed margins become major hurdle due to low resultant built area 2. for land parcels along narrow ROW (< 12 m) the height restriction limits the growth.

1.2 Assessment- Existing analysis PUBLIC SPACES
Inadequate public spaces While the area as close to 80 % area unbuilt and available as open space, only 15% of total open space is under public domain, clearly indicating lack of public spaces within the LAP boundary as per current population. With the redevelopment, the population influx is expected to increase exponentially, and this will result into an acute lack of area under public domain.

Even with the availability of 15% open space, the study done for streets clearly show the current condition which is completely dominated by vehicular use, rendering the use of “streets as public space” to be unsuitable.

Proposed AUDA public park
The figures clearly show the lack of available public green space. In the current proposal, only 1% of total area is available as open green spaces for public. With the increase in population density, the need of green spaces will increase many-folds. Even the 1% public green spaces available within the LAP boundary are undeveloped and encroached by slums or parking, effectively making available green spaces 0%. SPRING 2021
16
1.2 Assessment- Existing analysis Underutilized potential of public spaces While the public green spaces are extremely low in the site, large amount of green spaces are available in institutional areas, but they lack public accessibility. Thus, leaving large parcels of land completely isolated from public. Further, various publicly accessible buildings are located within the institutional parcels. Despite that, the areas stay isolated as the edges of these institutional zones are made opaque and inaccessible due to continuous boundary wall.

The public space character along BRT corridor is extremely underutilized or inaccessible due to parking encroachment and unregulated vending, disrupting the character of transit corridor. Thus, it can be clearly seen that the site has potential to create vibrant and active public realm through integration of underutilized areas and efficient improvement of existing public spaces. • Public plazas in front of commercial buildings aare left inactive due to lack of proper amenities

Developer’s Perception
A focused study through interviews of private developers was done to analyze the current market trend and financial feasibility of the projects for plots undergoing redevelopment. 4 major underlying points were concluded to have most impact: Increased FSI (4), even with chargeable component is largely sufficient and favorable. 1000 sq m. is minimum area preferred for redevelopment. 2500 sq m. is ideally preferred to achieve 4 FSI. Development of commercial floors on lower floors is preferred along major roads to strengthen financial feasibility. TDR is considered not in favor in current condition with limit after 4 FSI which is easily available.

LAP FRAMEWORK The chapter will explore the vision and LAP framework set for the area and the larger strategies to address the challenges
2.1 LAP Framework- Case Studies To address the identified issue of large isolated institutional blocks, a case for well integrated institutional campus is studied to expand the understanding of potential of the current site.
1. WU Campus, Vienna
The campus provides deep insights into unraveling the complexities of integrating a campus with the surrounding urban environment while still maintaining security and safety of each building. Campus area built up : 35,000 sq m Publicly accessible grounds 55,000 sq m
KEY LEARNINGS 1. The character of campus is made porous through central open area which is accessible from multiple entries throughout the day, improving connectivity through campus. 2. In addition to traditional academic infrastructure facilities, the campus also offers a number of facilities that are open to the public. (Restaurants, cafes and bakery, supermarket, bookstores, a childcare center, an athletic center and event spaces.)

Diverse Built-Form
Identification of zones which have potential to consume 4 FSI and form high density development on the basis of the street widths, further density, transit and assets establishing varying urban character. To maintain a coherent urban character through the major transit corridor built-to-line development is proposed. For the final density distribution, the plots not able to consume 4 fsi shall transfer the development rights to the plots abutting wider roads and can go upto 70 m in height. Amalgamation of smaller plots and increase of road width is suggested to utilize benefit of FSI.

The site is located towards southern edge of the delineated LAP boundary. The larger locational context clearly indicates that the site faces immense development pressure from surrounding areas which are redeveloping rapidly as TOD zones. It has a strong transit character owing to its proximity to both BRT and MRT stations, indicating potential rapid development. CN Vidhyalaya, one of the most prominent educational institute is located towards eastern edge. The area is primarily residential, with the institute acting as the anchor for the surrounding area.

3.3 Transformation Project- Anticipated development Potential Built Form To understand the challenges the area faces due to rapid redevelopment regulated by proposed LAP, a potential growth pattern on the site is projected. The residential area comprises of various Co-operative housing societies, apartments, and free hold plots. The newer development can be seen as affordable housing development which have mid-rise apartment typology.
Educational land Co-op housing Societies Apartments Free hold plots Affordable housing Public plot- AMC
The housing societies will result into large plots after redevelopment with over 3000 sq m of area which will follow LAP guidelines for built form. 39
Low-rise apartments occupy large plots which can immediately go for redevelopment without the need for amalgamation.
Free-hold plots with avg. plot size 350 sq m will need to amalgamate. However, limited growth will be seen along narrow internal street due to height limitation. URBAN TRANSFORMATION STUDIO

3.4 Transformation Project- Challenges
As the site undergoes transformation and the population density of the area increases, the site is contextually exam addressed to align the overall growth of the site with the set goals for the Ambawadi area.
Isolated Institute
CN Vidhyalaya covers 29.5 Ha of the area, and as understood, sits at the core of rapidly developing area. However, the institute still retains its isolated character with strong edge formed by boundary walls on all sides and only 2 regulated entries located towards north and eastern edge. The internal network of the institute creates dead ends while the scattered built form disrupts the overall urban structure of the area. With the availability of 4 FSI, the redevelopment of institute needs to be guided to better integrate the institute with the surrounding area. 41
URBAN TRANSFORMATION STUDIO

Indeterminate street character
Streets in any Indian city, or even world-wide act as essential, yet extremely complex public space utilized by various stakeholders. In current scenario the street guidelines are set in generic manner which deal with addressing the basic need of infrastructure improvement. The umbrella approach thus neither responds to the identity or character of the area, nor aligns with the goals of TOD. In that aspect, the existing street guidelines need to be built upon through redesigning of the streets rooted in contextual understanding and aligned with goals set for the growth of the area.

Design Intent The design intent for the area thus focuses on addressing the above challenges in comprehensive manner through envisioning the neighbourhood as a connected urban ecosystem that is rooted sustainable urban growth while simultaneously creating inclusive and vibrant urban spaces that responds to all users In that respect, the goals set for the neighbourhood are:
01 Integrating Institute
02 Re-imagining Streets
Responsive integration of the institute for improving the connectivity and enhancing the overall urban structure.
Reimagining the streets as the arteries of life which responds to anticipated high density growth.
These challenges are each taken up as projects to explore the strategies in detail that will be in conjunction with the envisioned development under LAP framework. SPRING 2021

Integrating Institute The following chapter elaborates on trigger project-1, which deals with idea of integrating the school with surrounding area
4.1 Integrating Institute- Existing condition and context
Existing Scenario
In the existing scenario, the intitute comprises of 4 separate zones: 1. Educational zone with multiple schools and hostel facilities located towards eastern part accessed through eastern entry which is used by students upto higher secondary level. 2. Fine arts college located towards northern edge 3. Hostels for located at southern edge for students enrolled in post-school studies 4. The sports and cultural zone with open play grounds and performance centre. This zone is allowed regulated public access. 1 Fine arts college area

Defined internal zones These zones contain various buildings with different programs, and each zone is defined by a porous boundary edge creating a “campus within campus” spatial structure inside the larger area of institute.
Dilapidated structures The institute is one of the oldest establishment with major existing structures built over 80 years ago. A lot of buildings are in dilapidated condition and lack modern amenities. SPRING 2021
46
4.2 Integrating Institute- Development model Instigating factors
As mentioned earlier, the institute has been operating since 1933, and most of the structures and infrastructure are in antiquated condition. However, the availability of FSI provides an opportunity to re-imagine the institute. In current scenario, 2 major factors act as instigators for the redevelopment. 1. Improvement in terms of capacity
As the surrounding area undergoes redevelopment, there will be exponential increase in population of the area. With increase in population density, a high rate of students influx is anticipated and thus the existing infrastructure will need to be improved to accommodate increased capacity. 2. Updated education policy-2020 The education policy introduced in 2020 outlines various factors which will greatly impact the facilities and infrastructure required in the institutes. Among multi-fold parameters, the following 3 might have most impact in dictating improvement in infrastructure and amenities: Digitization and AI based learnings in classrooms 47
Additional subjects and application based learning
Improved facilities for teachers URBAN TRANSFORMATION STUDIO
Development model The instigating factors provide the base for formulating a framework for development model. The core idea is focused on integrating the institute while simultaneously efficeintly utilzing the land.
LAP FRAMEWORK
In that regard, the development model will is achieved through two-fold process operating under both LAP, and framework for master plan of the campus focused onProviding better connectivity through campus without disturbing current functions • Under LAP framework, new connections through institute are established ensuring coherence of current use and functions. • The connections are to be part of LAP framework set for Ambawadi and the institute shall be required to follow the same during the redevelopment of institute.
CAMPUS MASTER PLAN
Potential for better land utilization for improved infrastructure and utilization of FSI
SPRING 2021
• The campus master plan will set the framework for expansion of current campus in conjunction with established network. • The unutilized FSI, if so remains after campus development, will be allowed to be sold off through TDR mechanism. Integrate with the city at large through opportunities for public realm • The design of internal network will explore the opportunity of creating active public realm that is inclusive of all users and is unambiguously part of public domain. • The internal connections will remain as part of campus under public domain, and shall be counted for FSI. 48
4.3 Integrating Institute- Strategies In keeping with the development model for institute, following strategies are implemented:
Connectivity
The internal connections are established with an intention of retaining the existing spatial zones based on current uses. The proposed connections are based on following framework1. Creating missing links to complete existing street network
Plot sold for p developmen
2. The existing internal network is bought into public domain and extended to integrate with the larger existing streets.
Land parcels development
3. The connections are further divided based on users as vehicular, pedestrian and regulated routes.
Inte int ex
The campus development focuses on efficeint utilsation of land that not only allows for expansion of existing facilities, but also improves the overall urban structure of the area The campus development framework focuses on 2 aspects: 1. The internal land parcels are utilsed for campus expansion with zoning done as per existing land use and internal connections.
49
2. The land parcels along external edges, adjacent to residential area are sold off for private development. The growth model allows for revenue generation for campus improvement and also opens up more developable parcels.

4.4 Integrating Institute- Design Internal connections design
The internal connections are designed to create dedicated pedestrian lane, and the vehicular lane is imagined as shared street. The entire campus will be designated as slow speed zone and regulations set on seed limits to ensure safety. The guidelines for campus may allow edges of each zone within campus to have porous edges with open green spaces aligned towards established connections.

The 12 m residential street currently has an inactive and unsafe character with continuous boundary walls as edges on both sides. With the proposal of campus redevelopment, the school edge will result into residential development. To respond to the residential character, the street is re-imagined as a neighbourhood street which can offer various interactive spaces for the residents, while being safe and child-friendly. This would be the link between residential neighbourhoods as the density of the area increases.

The 12 m residential street along railway track currently act as a parking lot, with a wall creating a solid edge disrupting the connection to the Paldi area. Furthermore, the current built form does not responds to the proximity to Metro station with restrictions on building heights. Thus, the re-imagined street focuses on creating a strong “destination” character for the street, which will lay foundation for guided growth that capitalizes on the proximity of the Metro station through built form and responsive street design.

The institute reinforces it’s identity as an anchor for the surrounding area through enhanced urban structure and accessibility that aligns with the larger vision for the city and offers opportunity to explore various possibilities of recreation in public domain. The corridor along transit route is programmed to create strong activity zone for the neighbourhood and improve the spatial character of the transit area focusing on diverse users. The internal zone of the neighbourhood sets a paradigm where the existing residential character is strengthened through re-imagining the street as a neighbourhood link which revives the community attributes of public space through careful programming. The transformation of the area is thus imagined as a well integrated neighbourhood, that acts as an urban ecosystem with a series of vibrant and inclusive spaces that responds to distinctive character of the surrounding built environment as well as various stakeholders. 74
