INTRODUCTION

VARGENS, THE LATENT URBAN LANDSCAPE The 2012 fall semester urban design studio continues the focus research on Rio de Janeiro, the second most populated urban area in Brazil, and a city of growing national and continental importance. Selected to host the 2016 Olympics and some events in the 2014 World Cup, Rio de Janeiro is being transformed through massive investments to modernize and expand obsolete urban infrastructures, respond to the shortage of urban services, and improve security across the urban geography. Beyond these investments, the emergent geopolitical significance of Rio de Janeiro in the South American continent revolves around a robust and diversified economy, including the thriving oil sector tied to the discovery of massive off shore oil fields nearby.

Fostered by the optimism of this booming economy, Rio’s population projections estimate a steady increase in the next decades. As a consequence, the city fabric will continue to expand on undeveloped and protected land to house a growing number of new-comers in a market with chronic shortage of residential options. The design challenges emerging from these dynamics require innovative approaches to better balance the demands of growth with landscape protection and resource conservation.

The studio structure encourages the use of innovative approaches to traditional urbanization mechanisms— urban infrastructure, blocks, parcels, and building typologies— and the deployment of an extended repertoire of urban design elements and ecological strategies pertinent to the site. The dynamic collaboration among students facilitates the development of responses at multiple geographic and temporal scales, incorporating cultural and social concerns and process-based dynamics of development in a site with high ecological value and multiple infrastructural constraints in the municipality of Rio de Janeiro.

INTRODUCTION

The testing site for the studio is the Vargens, in the southwest of the municipality of Rio de Janeiro, and adjacent to the area master planned by Lucio Costa in the late 1960s. The area is a key ecological piece in the transition from the National Park of Pedra Branca (one of the biggest urban forests in the world), and the sea front ecological system formed by the Chico Mendes Park and the Lagoa de Marapendi.

The Vargens is already set for development as defined by the PEU, a municipal planning regulatory framework with highly flexible rules for developers and very vague environmental constraints. Guided by a market-driven approach, and capitalizing on a sense of urgency to respond to housing scarcity, new residential developments are popping out in the area in a piecemeal fashion. This lack of a cohesive structure in the strategy of development of the Vargens threatens the ecological value of the central wetlands in the landscape matrix connecting Pedra Branca and the sea front.

1 The second semester of the Urban Design Studio sequence “focuses on the planning and design of sustainable physical environments anchored by a residential component as a catalyst of vibrant urban life�.

(Left) Images from the site showcasing the patterns of land development.

Building on the curricular structure of the Masters of Urban Design1, the studio speculates on the design opportunities emerging from these dynamics to serve a diverse population through the development of inclusive urbanization frameworks.

The semester is structured around different exercises, including mappings on the site connections at the metropolitan scale, research and analysis of existing site conditions (observation), diagnosis (assessment of those), and design development engaging the cultural and ecological dimensions of place (synthesis). The two final team schemes include: (1) studies on land use strategies, urban blocks and building typologies, with an emphasis on the residential component; (2) programmatic and performative considerations in the design of open public spaces; (3) site integration in the metropolitan infrastructural systems, and strategies for the protection of the site ecological balance; (4) individual design proposals for the selected areas of focus in each scheme; and (5) stakeholder identification and implementation strategies.

METROPOLITAN CONTEXT RIO DE JANEIRO AND THE BUS RAPID TRANSIT The BRT system, which is already running in Barra da Tijuca, is slated to be fully operational in time for the city’s hosting of the 2016 Olympic Games. Composed of three intersecting routesTransCarioca, TransOeste and TransOlimpica- the completed network will stretch 120 kilometers and feature 133 stations and be integrated to the region’s bus, rail and metro systems. Much of the system’s alignment is strategically located to promote Transit Oriented Development along designated future growth areas, ushering in a new era of mobility in the rapidly growing metropolis.

The 25 kilometer Transolimpica BRT route traverses central Rio from north to south, stretching from the regional rail network’s Deodoro station to its terminus near Lagoa de Marapendi linking up with the TransOeste route. Much of the route transverses what is now relatively low density residential and agricultural landscapes. The northern terminus however is dominated by expansive military installations and barracks.

The TransOlimpica corridor runs across Rio’s difficult terrain ,which it negotiates with a nearly 4 kilometer tunnel.

THE SITE The area known as “Baixada de Jacarepagua” in Rio de Janeiro, was until the last third of the past century, a spectacular wild scape composed of swamps, wetlands framed by the Tijuca’s mountain chain -“Macizo de Tijuca”. However the blooming city’s economy, massive migration processes and rapid urban growth put enormous pressure in the area.

In the 1970’s, Brazilian famous architect Lucio Costa was commissioned by the city of Rio de Janeiro to masterplan a first pilot for the “Baixada”, envisioning it as a new urban centrality, the “hearth” of Rio facing the Atlantic. A linear 20 Kilometers development with high rise residential cores every kilometer, equipped with retail an amenities in a “zig zag” secondary grid, a new city center, and a preservation area containing wetlands, watersheds, pastures and an important biodiversity called Vargens-Camorim.

Nowadays, the city’s thriving economy, an unsatisfied demand for 240,000 residential units, and an everyday stronger and more “influential” real estate industry, have put this area in the development plans of the city. Resulting in the special site regulation called PEU 104, which rather than considering the ecological conditions and functions of the remaining local ecosystems, have responded almost exclusively to the needs of the city’s real estate market.

Vargens is located in the southern expansion zone of Rio de Janeiro, near Barra de Tijuca and the future 2016 Olympic Village, 40 kilometers far from downtown Rio de Janeiro. It occupies an area of 51.4 square kilometers, almost the same size as Manhattan. The maps in this section detail the Vargem area’s current characteristics. 36% of the site is urbanized, with 22% found in the consolidated area, and 6% in non-consolidated areas. 3% of the developed lands are favelas and the remaining 3% are in cultivated fields. The current transportation network is heavily car oriented, which leads to 200 meter-long urban blocks and streets.

It established this region as the node that completes the circuit of development of the city by connecting Madureira and Penha to the core city. It proposed two sub centers of Sernam be Tiba, on the west and Barra on the east with high-rise residential along with public amenities. Further the plan proposed residential nuclei at every kilometer, along the Avenue da Brazil with 34

small retail activity. The public amenities were located on the opposite side and are connected by diagonal road network. This is intermediately intersected by pedestrian pathways. The main center, located on the road connecting Barra to Madurera, was further divided into 16 blocks. The central blocks consist of high rise buildings, 200m, while the peripheral blocks constitute of low rise development.

Existing road network

The primary road in Vargems is Avenida das Americas, which defines the southern edge of the site and features the Transoeste BRT line. A secondary road named Estr. dos Bandeirantes winds along the northern edge of the site, following the topography of the foothills. These high volume roads are connected by two distributer roads named Estr. Ver. Alceu de Carvalho and Estr.Benvindo de Novais. Excluding these four roads, much of Vargem’s existing transportation network contains unconnected paths exclusively serving a specific development, and often dead end into wetlands.

As a part of Amsterdam’s urban waterfront development plan created in 1985, Ijburg island’s design intends to dyke in and reclaim Ijmeer bay with the aim to create a new urban extension. The design is derived from an 1965 linear city expansion plan and converted into a loosely arranged archipelago. Ijburg consists of six islands ranging in size, block size, building typology and land use. The arbitrary shape and composition of the islands is contrasted with the structured grid organizing each island. Within the islands, the basis of the plan is a superimposed urban grid which does not impose a certain look but allows for a balance between order and randomness, cohesion and variation.

EASTERN HARBOUR DISTRICT AMSTERDAM, NETHERLAND

This is an urban regeneration project which involves the conversion of the eastern harbour district in Amsterdam into a residential district. The district is built on an idea of recreating traditional Dutch neighborhood and also making use of the water as a designated open space.

The study focuses on the Borneo Sporenburg islands which are majority low-rise residential with two high-rise towers accommodating the social housing component. The housing is undertaken by a variety of architects guided by a set of rules and regulations which generates interesting variation in the housing typology.

The third agent will be represented by national and international organizations (The World Bank) interested in contributing (with capacities and economical resources) to the preservation and implementation of the green infrastructural component. All these agents can be able to work cooperatively through the implementation of a large scale urban endeavor of this type.

ENVIRONMENTAL INFRASTRUCTURES Timothy Bevins A framework for ecological resilience is established with an overarching site plan that evokes moments of natural systems extending into the urbanized fabric and vice-versa. Wetlands are remediated and augmented with a system of islands capable of supporting species that both clean and slow incoming water from the mountains. A network of promenades, public spaces and trails bring users into this functional landscape, but do not tread heavily upon the natural systems.

In this proposal, these two systems are tightly integrated yielding a networked exchange between the built and ecological surroundings while providing a cultural anchor for the Vargems area.

The site’s cultural programs are positioned along a corridor extending from the main transit line towards a promenade facing the conservation area. The proposal defines a dynamic soft edge for the urban and ecological interchange where wetlands extend into the urbanized areas under responsive building typologies, and specific programs expand to the ecological area and build the ground.

MULTI-INTERLIGACAO Cesar Simborth Escudero MULTI-INTERLIGACAO or “Multiple Interconnections”, is the name given to one of the moments in the Overall’s Vargem’s Master Plan, in which one of the main residential linear transit oriented fingers encounters, interconnects and converges with the “Barra-Recreio” Rio’s urban linear system, now being spined by the new Transoeste BRT corridor.

It is in this point that a set of multiple functional interactions between the “new district” and the city are to take place. Dwelling, commuting, shopping, working, services and urban leisure will be the main functions of the area, allowing for different flows of people, economy, energy and nature converge, converse, and interwoven into a place that accounts for not only a point of entrance for the new macro development proposed, but a new destination for the area of “BarraRecreio dos Bandeirantes” in the South-West of Rio de Janeiro, which is currently a large 20 kilometers linear residential expansion still dependents on the city’s main attractions far North and East.

RECREATION ANCHOR Shuqi He The proposal for this district explores the interplay between the dynamic condition of the public space along the water spine and the social life in the district. The site is located in a transitional area where the existing urban fabric merges with the proposed finger scheme, and the streams and biking path coming from the mountains find their way to the conservation lands.

The project strategy articulates a series of residential, commercial and recreational uses along the network of open spaces, and capitalizes on water as both resource and amenity. Two systems of public promenades negotiate the multiple scales of water on site: (1) a series of courtyards register the flow across the urban grid, and (2) a series of topographical platforms incorporate multiple recreational areas descending to the lagoon, at the heart of the conservation area.

COMMUNITY LIFE Sneha Lohotekar Housing design can unite as well as divide, it can engage or detach, it can eventually result into a close knit community with its inherent values or enter the shadows of a gated community. This design is an attempt to nurture this engagement into a residential fabric considering the vibrant street life and social context of the city of Rio de Janeiro.

It intends to house the diverse categories of people from different economic and social strata along with diverse age groups of Rio de Janeiro’s society.

This diversity and engagement is achieved through an conscious hierarchy of public spaces as grounds for interaction The water and the natural edge has a vital role in the revitalizing this public realm.

THE BELT

The BELTS proposes a multi-layer scheme to accommodate both the conservation of the rich ecological qualities of the site and the pressing urbanization dynamics that have targeted this area as the next urban frontier in the metropolitan geography.

The scheme defines a central green-heart covering the main central wetland, the different BELTS deploy a system of varying densities of development and programmatic funtions: two kinds of recreational 112

uses, a multi-modal transit strip, a green belt, and other institutional and residential layers. As the different BELTS wrap eachother, local centralities emerge in the site offering a distinctive identity to different districts and neigborhoods.

Other than the BELTS, the scheme deploys two north to south corridors to ensure transportation and ecological connectivity from the mountains to the ocean.

The proposal further develops five prototypical subcenters depicting the main features of the scheme.

THE GREEN CORRIDOR Jia Weng This proposal is located along one of the green corridors connecting the mountains with the Green Heart, the conservation area, and it places water infrastructure as the backbone of the strategy for urbanization.

The proposal addresses the need to reserve space for the existing streams to perform a regulatory function in the storm water management strategy as a central element in the prevention of flooding. While responding to the pressures of growth and additional housing units, this area offers lower densities than surrounding districts. As a counterpoint, the proposal introduces a multi-scalar system of storm water management techniques from the scale of the whole corridor to the one of the block.

LIVE WORK DISTRICT Dongye Liu This district spans along the transit line, north of the Green Heart, and aims to achieve a walkable urban neighborhood with a mix of residential, commercial and institutional uses. The urban grid registers the different belts running across the transit line, and adopts different configurations of public space and building typologies to participate in their different natures. From South to North, the proposal adapts to respond to different adjacencies: it hints on potential relationships with the Green Heart, and merges with the existing fabric in its way to the mountains.

THE RECREATIONAL WATERFRONT BELT Yu-Hsiang Lin The Recreational Waterfront district signals the transition from the urbanized multi-layered belts to the Green Heart, the central conservation area at the core of the site. Anchored by two of the north south connectors, this district incorporates a series of commercial, residential, cultural and recreational uses, and articulates different opportunities to experiencing the ecological reserve. In the Waterfront Belt, the urban grid loosens up: the landscape is set in motion and it creates new ways to inhabit, interact and experience these hybrid grounds.

The Recreational Waterfront articulates a dynamic common ground inspired in the Rio de Janeiro beach culture: attractive and well-designed open spaces that add amenity-rich destinations for residents and visitors alike, facilitate social interaction, and improve ecological biodiversity.

THE CENTRAL MARKET Pei Liu This district is one of the new centralities in the Vargens area, at the intersection of one of the north south-transit connectors, and the Central Market Place.

The multi-layered belts meet with the transit line in this area and result in a high density area. The loop splits and merges together with the mixed use belt to form a public strip that houses the Central Market and a public plaza. This market spine acts as a public ground and activates surrounding residential and commercial uses and leads to a vigorous mixed life district.

THE DOWNTOWN GATEWAY Chi-An Wu The Downtown District signals one of the south gateways to “the Belts” in the Vargens area. This new centrality holds higher densities than the surrounding districts and capitalizes on the high transit accessibility from both the Transoeste BRT line and other local bus lines.

Following a south-north transect, the system of multi-layered belts in this area registers a storm water regulatory water canal, residential grounds, the infrastructural loop, a retail and office strip, and recreational programs facing the green heart.

Building on the high density of the district, the “belts” strategy becomes three-dimensional and articulates different levels of porosity in the building typologies to ensure urban block permeability and visual connectivity across the site.
