The Tunjuelo River is located in Bogotá’s Southwest zone, and as the water flows downstream from the Páramos, it faces a significant increase in pollution. Additionally, the river tends to get lost and erased in the articulation of the urbanized areas. The water quality of the river is drastically decreased from its source in La Regadera dam until it reaches the farthest portion in the middle Tunjuelo, the Bosa neighborhood, where it cuts through four massive pollution sources: crops, landfills, construction sites, and tanneries.
To revive the Tunjuelo River, our project aims to integrate meanders into the existing urban fabric, initiated by the Tunjuelo Guardians’ proactive approach. The meanders of the Tunjuelo River were once responsible for slowing down its flow and increasing its holding capacity. Today, with its meanders cut off for urban development, the river floods, and is heavily polluted. Therefore, our project focuses on slowing down and cleaning the Tunjuelo by reintroducing meanders at multiple scales and for varying levels of flow within the river and the existing city fabric. This initiative creates a sense of collective place and opportunities for water and society to shape and reshape each other, coexisting in a relationship of reciprocity.
Community participation is essential in this process. Existing and new environmental stewards from the community play a crucial role in enhancing the environment for future generations. Ultimately, making it a healthy and thriving ecosystem that benefits both the community and the environment.
Reya Singhi, Saloni Shah, Nupur Shah team.Analyzing the river as the central actor at a zoomed-in scale reveals the disconnection between the water system and the surrounding neighborhoods. Concretized riverbanks and stagnant water ponds compromise the water system, contributing to a lack of belonging for residents. At a smaller scale, most edges of the river are marked by fences and garbage, which generates household waste and increases pollution in the water.
The middle Tunjuelo region is particularly affected by pollution from the tanneries located in San Benito, from where the polluted water flows downstream. Ultimately, this polluted water ends up in Bosa, the lowest basin of the Tunjuelo River.
MEANDERING WATERS
The meanders of the Tunjuelo River once worked to slow its flow and increase its holding capacity, filtering and eliminating pollutants, allowing the ecosystem to thrive.Until a few decades ago, the river was a connected system with the expansion of wetness throughout green large areas, and the growth of urban areas respecting the river flows allowed the neighborhoods surrounding it to thrive (7.2).
CHANNALIZED RIO TUNJUELO
Over the past ten years, the river has been chopped, cut and sculpted, reducing its surface and eliminating meanders from its winding paths. This erasure had a negative impact on the nearby neighborhoods and continues to be a major cause of serious floods. Bosa, at the basin, ends up being the most impacted one and despite efforts to mitigate, the underlying issue still persists (7.3).
AN INTEGRATED SYSTEM
Our project’s main goal is to slow and clean the Tunjuelo by retrofitting the urban fabric to reintroduce old meanders and create new ones in the middle Tunjuelo. At multiple scales, it will allow the floods to be mitigated before it reaches the lower parts of the river, as well as fitrate the polluted water coming from upstream (7.4).

TINGUA AZUL WETLANDS AS A SAMPLE SITE
The Tingua Azul wetland is part of the former natural flood zone of the Tunjuelo River. The wetland is quite affected by the passage of Villavicencio avenue that divided it into 2 sectors, eastern and western, with its consequent high level of noise and air and garbage pollution that both affect these ecosystems. The Tingua Azul retrofit envisions bringing back the lost ecosystem by reviving meander paths and integrated wetness, as a part of the Mayor’s program’s 14-year plan in place to protect the wetlands.

SAN BENITO AS A SAMPLE SITE
San Benito tanneries are the major source of pollution of lead and chromium metals directy polluting the Tunjuelo. Due to this continuous contamination of the river the people of the neighborhood are under a constant threat of second displacement by the government on the name of environmental protection which would lead to the loss of their livelihoods. The project starts to implement the strategy of de-concretizing the impervious surfaces by cutting and filling the soil, creating a gradient of high and low lands capable of restoring the water flow. Along with the formation of the meanders, it creates more opportunities for social gatherings around.

Atlanta and its communities have fallen victim to the city’s decision to facilitate cars that have embedded and layered divide throughout the city. Thus, the routes are controlled and land remains vacant to accommodate the convenience of the few over the lives and relations of the many. Downtown Atlanta stands as a testimony to the state’s misplaced priorities.
State-enforced parking lines are recognized as mechanisms that promote direction, control, and isolation, and the project critiques the marked methodologies that promote ownership for capital endeavors, leading to the hoarding of land for future profit.
The project’s main objective is to imagine a world beyond property that isn’t subservient to individual interests, leading to the contemplation of a world without cars. The proposed solution is to remove the urban systems that dictate the landscape, starting with the elimination of roads and redefinition of streets. Strategies are then proposed to remove and reorient the parking lines that have populated the vast landscape. The aim is to reimagine these lines, which have divided people for years, and create coherent communal systems that encourage growth.
Ultimately, the project aims to wash away years of directional marginalization and create a more equitable and sustainable urban landscape that prioritizes the needs and wellbeing of its community members.

In this new world, the lines serve as a reminder of a past on the brink of breaking. However, they are no longer vacant lines on asphalt hoarded by the wealthy. Instead, they have been reoriented and restructured as spaces that embrace and accommodate collective existence.
Pedestrian paths have been built to lead into these spaces, blending the landscape with vegetation and reminding us of the ecologies lost in our pursuit of capital. Accessible by a new tram line connected to the existing metro, no cars are necessary. As a result, a combination of logical and illogical nodes have filled the area, breathing new life into downtown Atlanta and empowering its people.
a Blue New Deal for Sausalito
Towards Resilient Cities+Landscapes Seminar
Developed with assistance from Sausalito’s Mayor Janelle Kellman and the Woking Waterfront Coalition
Fall 2023
LINK 01
Sausalito is a coastal city in California that faces a range of challenges, including the threat of rising sea levels due to global warming, seismic activity, and landslides. The city’s infrastructure, including sewer and stormwater systems, is vulnerable to flooding, and development constraints limit affordable housing options. Despite these challenges, Sausalito has a rich cultural heritage, including a working waterfront that supports the city’s economy. However, real estate interests are pressuring the City Council to re-zone the waterfront for high-density housing and commercial use.
The Blue New Deal strategies are being applied in Sausalito to help the blue economy while protecting and accommodating the environment. The solutions include developing offshore wind energy with foundations used as artificial reefs to farm seaweed and other aquatic life, creating floating research and training job centers, building a barrier island of sand to reduce flooding risk, restoring tidal marshlands, creating nearshore reefs, and re-adapting office buildings for Blue-Tech innovation centers. Additionally, planting native trees to prevent soil erosion and adapting to greener energy usage is essential, including community-wide rainwater harvesting, solar panels, and multi-family housing.

After conducting a thorough analysis of Canarsie, a neighborhood in New York City, including its economic, political, and social fabric, as well as its devastating aftermath post-Hurricane Sandy, the project was fueled by the opportunity to establish a Community Land Trust model. By separating land ownership from housing ownership, homes are removed from the unstable property market and can provide CLT residents with opportunities to build shared equity.
This empowers the local community, which has experienced many hardships since the hurricane, to thrive and take control of its own future.
The aim of the project is to re-envision housing for the people, by the people.

strategies phase III: co-housing development, ADU solidifiction and edge condition rough design.
The Canarsie Commons Community Land Trust has a plan consisting of four phases to address housing and safety concerns, using CLT methodologies, urban planning, and design. After its establishment, the focus was on purchasing vacant public lands and acquiring the land of current owners in the Opportunity Zone - on higher ground - to build enough housing stock to accommodate future changes.
Partnered with community-based organizations to leverage research into the specific context in which Canarsie is situated, we pushed forward the existing proposal to rezone some residential areas located in the high ground of the neighborhood to increase the building height of the currently allowed housing typologies.
Concurrently, a new deeply affordable housing model was designed, including shared green and communal spaces to empower collective ownership of land and resignify the relationship of the residents with their homes and continuous threats.
Lastly, the final phase would dive deeper into the potential to restore the existing marshlands, relating its study to the direct impact of flooding and how a resilient future for Canarsie can be built to overcome the real threatening future predictions.
While the rezoning process takes place in order to build the co-housing in the highlands and away from the edges, one of the proposals studies the implementation of ADUs to existing houses in a neighborhood block.
ADUs would spread over time, freeing owners from flood insurance and providing open space for residents. As a consequence of this increased density, the city would begin to take action into improving the public space, including streetscapes, bike lanes and broader sidewalks.
ADU’s units that can be either attached on the top of the building or detached to an existing home that already sold the land to CLT. They are modular, making them easily replicable and quick to build, ensuring a relatively fast allocation of the residents living below the DFE (Design flood height elevation).
Lots that are bigger, could eventually allocate medium density housing with few units, along with shared community and open spaces. The model suits alll audiences. In this study additional 40 units in the block were created with an average housing of 20 families.

Maria Fernanda Lemos tutor.contribution. This project arose from the need and opportunity to reverse the linear production process that I call “productwaste.” By reversing the process and making part of it circular, it is possible to turn solid waste, both terrestrial and marine, into an energetic product. The complex has at its core a large infrastructure: an industrial, environmental, and educational complex that develops around the WtE - Waste to Energy - system, a form of recovering clean energy by the controlled combustion of solid industrial and domestic waste. The master plan is, therefore, a large infrastructure that houses several subinfrastructures to promote benefits for the surrounding communities, while simultaneously using it to meet the energy needs of the city itself.

The project is partially located in the Caju neighborhood and on the southern portion of Fundão Island, in Rio de Janeiro’s city center. This section was chosen due to several factors: it is the city’s most extensive port region; it hosts a large number of expressways linking to the Rio-Niteroi bridge; it has a resistant resident population, going back to the early days of the city’s occupation; it has one of Rio’s most complex urban meshes, as well as social, economic, and political contrasts. Finally, it is an area that was gradually degraded and abandoned in the waves of the revitalization of the port region. In the past 50 years, it had an 80% reduction in fauna/flora, disposed of 18 thousand liters/second of raw sewage, and 90 tons of waste per day.

The landscape and urban design project is located in the heart of Córdoba, a municipality in the province of the same name, in the autonomous community of Andalusia. By analyzing Cordoba’s occupational history to better understand urban dynamics, we were able to map how the city gradually developed and how its territory is used. First, the natives lived there due to the good location and land potentials; VIII BC Phoenicians came seeking silver, gold, copper, and tin; 206 BC the Romans invaded and established a military camp for their troops; 5AC the Roman Empire fell and Vandals and Visigoths sacked the city (the former giving the Andalusian region, its present name); 711 the Muslim invasion took place, actively supported by the Jews, as it would mean the end to over a century of persecution suffered at the hands of the Visigoth kings; 833 Irradiating center of culture and power, it was home to the biggest public library in the world; the final occupation in 1236 led by King Ferdinand III, a Catholic, who conquered the city and eradicated the Muslims.
Because of its rich history and cultural importance, in 1984 the town was declared by UNESCO as a World Heritage Site. From 2000 onwards there have been new neighborhoods and infrastructure until it became the modern city we know today. Shortlisted as the European Capital of Culture in 2016, the city has a vast and exceptional history, as well as excellent examples to relive the splendor of past times.

The concept of the proposal is to unify the old and new identities of the city of Córdoba. Through the assessment of topics such as viewports, land heights, landscape visibility, historical background, natural flora and fauna, and cultural celebrations, the project’s conception starts with the occupation of focal points in the city, which are connected through the suspended walkway. The 3km long suspended walkway follows – at times physically and at times conceptually – the perimeter of the old wall. In its above-river portion, it adapts into an organic form, following the flow of the Guadalquivir river whilst creating new homes for the living fauna around the area and opening new possibilities of attractions for tourism. The observatory at the highest point of the walkway is set at the south point, where the city can be appreciated as a whole. Its shape is designed around the idea of the daily-sun path, as it is born in the east and sets in the west.
Evaluating the different bird species living around the riverside of Cordoba led to the proposal of a new idea for the project, taking ecology into consideration. A system of combined trusses would allow the birds to nest and build their new homes around our new construction, above the river.
Restoring a natural habitat was the first step. We later introduced other features and uses to the complex: focal and new tourist attraction, restoration of the historical part of the city, the reunification of the ancient wall of Cordoba, new pedestrian flows and networks giving a new identity to the city. The financial aid of the proposal is based on the contribution from the public and the private spheres. It is a large project, with different construction phases, but certainly capable of bringing a harmonious combination of the modern and the old to this beautiful city in Andalusia.

The project contemplates a high-end 12-story residential building located in the heart of the city of Rio de Janeiro at Prudente de Morais St. in Ipanema. It reflects the lightness of the carioca spirit as an exclusive development designed by a top rated team of experts in each phase of the project.
The contrasts and nature are an invitation to contemplation: on one side, the beach. On the other, Rodrigo de Freitas’ lagoon.
The mobility is facilitated by easy access to several public transportations. Close to two subway stations, it is 450 meters from the Nossa Senhora da Paz station and 600 meters from the General Osório station.
From walking along the beach waterfront to outdoor sports, the beloved Carioca neighborhood has a wide variety of the finest restaurants, services, and stores around the city of Rio.
The balance between the rigorous aesthetics of architecture and a playful lightness is one of the main aspects of the project and it becomes even more unique as each of the 24 apartments has its plan designed individually, according to each client’s needs and personal style but keeping the façade unique.
