ABOUT ME

I am a fourth-year BSLA student who is preparing to graduate. I have developed my skills in research and community engagement, with a particular focus on addressing social marginalization and environmental injustice. Through my studies, I have gained a deeper understanding of urban challenges at various scales.

During my internship at the National Forest Foundation, I worked on projects that involved engaging young people in conservation efforts and developing educational programs focused on environmental stewardship. At the US Forest Service, I gained a better understanding of forest management practices and their impact on ecosystem health and biodiversity. Currently, in my position at Here LA, I help conduct comprehensive assessments of Metro bus and train stations in Los Angeles, identifying areas for improvement to enhance the overall quality of the transit experience and promote sustainable urban mobility solutions.

I am determined to pursue a career in landscape architecture, seeing it as an inherently optimistic discipline with the power to bring about positive transformations in spaces and communities. My motivation to excel in this field comes from my desire to contribute to the creation of healthier and more vibrant communities.

INTRODUCTION

RESHAPING FUTURES THROUGH MEMORY AND LAND Boyle Heights, CA Instructors: Claire Latané, Adrian Tenney, and Robert Douglass Fall 2023 Boyle Heights is a place of great historical significance, and we are committed to uncovering its rich layers of history for all to see. Our aim is to provide a living tribute to the Tongva legacy by creating a dynamic and forward-thinking environment that encourages community engagement and reflection on the shared heritage of this sacred space.

In designing our outdoor learning spaces, we have sought to blend the historical memory of the land with contemporary needs. We believe that the school campus can become a central resource hub for the community, and we have worked hard to create a Community school model that encourages members of the community to activate these spaces.

At the heart of our work is a deep appreciation for the transformations that have taken place on this land. We seek to honor the memories of the land by highlighting the way that humans have shaped the landscape over time. For example, we are particularly interested in the sacred spaces of the Tongva villages of Apachianga and Yaanga, which have remained invisible in contemporary Los Angeles.

Sheridan Elementary school is located less than a mile from the Sacred Sha’var, a Sycamore tree that stood for over 400 years and was a gathering space for the Tongva indigenous people. The tree witnessed first-hand the way that the landscape was shaped, first by the indigenous people and later by the colonization of Spanish, Mexican, and American settlers. By exploring these transformations, we hope to deepen our understanding of the rich history of this land and its people.

COMMUNITY ENGAGEMENT ACTIVITIES

Place it workshop: We utilized students’ most cherished childhood memories of play to develop our playground design proposal. By tapping into people’s memories and imagination, we were able to generate innovative solutions. This workshop includes creative ideas inspired by childhood and aims to draw upon the expertise that resides in our memories of the past.

GOALS: Through material designs made by participants themselves, this method improves communication, inquiry, reflection,collaboration, ownership of the process, and idea generation in a playful manner.

FORMAT: The Place It workshop makes the creative process of community design accessible to residents through animated visioning activities. The workshop participants imagine their ideal playground using found objects.

MATERIALS: The materials should consist of everyday, nonrepresentational, such as colorful beads, painted blocks, hair rollers, pipe cleaners, and other nonarchitectural objects.

INTRODUCTION

WEAVING CONNECTIONS Mountain Center, CA Instructor: Andrew Wilcox Spring 2022 Camp Woodcraft is a wonderful overnight mountain camp located in the beautiful San Jacinto Mountains near Idyllwild.

The camp is run by Woodcraft Rangers and is inclusive and affordable for LAUSD students. The values of Camp Woodcraft focus on connecting students with the natural environment and nurturing connections with others.

Our programming and planting plans were also inspired by the ethnobotanical traditions of the Cahuilla people. The design featured Deer Grass, which was the main plant used in basket weaving and is native to the region. We also incorporated other plants guided by native plant communities such as California Sage scrub, Oak Woodlands, and California Chaparral plant community.

We were thrilled to partner with Camp Woodcraft to design a space near the camp dining hall and one of the camp’s fireplaces. Our design was inspired by the principle of weaving, taking traditional weaving patterns used by the indigenous Cahuilla people as precedents to create a flow similar to that of a basket weave.

We are proud to have contributed to the development of a small part of this amazing summer camp and hope that our design will help students connect even more deeply with the natural environment and with each other.

INTRODUCTION

PAISAJE DEL SOL Mexicali, Baja California 3er Concurso Internacional de Arquitectura de Paisaje Team Members: Johanna Ortiz, Victoria Bruno, Angelica Diaz, Wendy Rosales, Nathan Liu, Alex Lopez and Daniel Bautista Summer 2023

The Sonoran Desert is a unique place where cultural and biological diversity interact. It is the most diverse desert in North America. Unfortunately, human activities like cattle grazing and industrialized agriculture have led to the loss of up to sixty percent of native vegetation. The development of dams has also altered much of the Colorado River delta, resulting in the disappearance of many tributaries.

Restoring biodiversity in desert riparian areas is necessary for the Sonoran Desert ecosystems and the wildlife that depend on them. Although these areas occupy only five percent of the region, they support ninety percent of its birdlife.

Woodlands containing Palo Verdes, Ironwoods, and Desert Willows are found in these desert riparian ecosystems.

The city of Mexicali has been trying to address the restoration of desert riparian corridors through the Corredores Verdes initiative launched in 2012, which aims to plant native plants along the Rio Nuevo to improve air quality and beautify the city. Our site is located on the Zona Rio Nuevo, where the city of Mexicali hopes to restore the area as an important ecological link for the rest of the city.

Our landscape proposal is influenced by the biological diversity of the Sonoran Desert, and we aim to rehabilitate the site that has suffered from a long period of environmental degradation. By incorporating native plant communities, we can support an array of native pollinators that will affect the habitat and food chain of many other species.

We collaborated with individuals associated with the Sonoran Institute, an organization known for leading community-centered conservation projects in the Colorado River Basin. As we were students from a different city, we realized that understanding the community’s needs within a short timeframe would be a challenge. Therefore, we leveraged local connections to establish potential partnerships.

Ángela Meléndez, who is affiliated with both the Sonoran Institute and Universidad Xochicalco, shared valuable insights into Mexicali’s vibrant atmosphere, bustling streets, and water accessibility. Her inputs had a profound impact on our design choices. She emphasized the necessity for shaded spaces, the popularity of skate parks, and the appeal of Tianguis among Mexicali residents.

Tijuana River

!

Tijuana is located in a region with hilly terrain, where over 30 percent of the population resides on slopes that are at risk of erosion. The rapid urbanization of the city has made it difficult to address the increasing threat of landslide hazards. As a result, there have been over 40 recorded landslides in the past 20 years.

More recently, Tijuana has seen an increase in large scale subdivision development. The largest developers in the city, such as Grupo Melo, Grupo Frisa, and Grupo Ara, are continuously building in areas that are prone to hillside instability. This analysis maps high risk areas that would benefit from erosion control strategies, and highlights areas affected by developments that disturb the integrity of the soil and make it more susceptible to erosion.
