BEYOND THE DUNES

A CALIFORNIAN PICTURESQUE

SAN FRANCISCO, CA FALL 2021

MLA ACADEMIC PROJECT (INDIVIDUAL) LANDSCAPE ARCHITECTURE DESIGN INSTRUCTORS:

PROJECT STATEMENT

Golden Gate Park, the central park of the west coast, was designed and built during 1860s. It sits on the west side of San Francisco and faces directly to the pacific ocean. It witnessed the urban expansion over the centuries.

The park now serves as an oasis of busy urban life, but it was a true coastal desert before its birth.

In this project, I will focus on creating new experience that brings back the dune history in the west side of the Golden Gate Park and the Ocean Beach.

VISUALIZED NATURE

Hardscapes won’t move, but sand will. The power of nature will gradually change the dunes. A series of short walls, pavements will create different sand accumulations. It will helps human visualize how our landscape can change over the years.

PROGRAMS

Multifunctional Lawn

The lawn area can be used as a picnic space in the daytime, but can also be transferred into event space as well.

Bridge + Overlooking

Because the park topography was higher than the beach, the bridge take people from the park to the oceanfront with a very gentle slope. It also provides a 180 degree view of the pacific ocean.

Section A-A

Mount + Overlooking

The mount resembles the natural mount landscape in the bay area. The deck on the high point provides a great view of the park, bridge, and the ocean.

Museum

The museum will be dedicated to the education of the bay area cultural and natural history. The structure and the surrounding landscape will bring popularity to the west side of the park.

SECTIONS

The park is designed with different elevations to create view points. The bridge structures also level with the park and move people across the highway smoothly.

UNDERGRADUATE ACADEMIC PROJECT (INDIVIDUAL*) LANDSCAPE ARCHITECTURE DESIGN

INSTRUCTORS: KIMBERLY GARZA, ERIK PRINCE

PROJECT STATEMENT

Every piece of the landscape has its value and has been built for some reason. But the value could change over time.

The focus of this project is the Old Sacramento Waterfront. In the process of exploring its historical roles and analyzing its current values, I proposed a design that embodies its past values to fit our current world. I hope the design could let people rethink our relationships with similar infrastructures in our urban environment.

The waterfront now served mainly as the Structural support for the safety of the city and Social gathering spot for both locals and tourists.

Even the Old Sacramento Historic District is the top one tourist attraction in the city, most people visit here are not for the waterfront. As much as people love water, the lack of accessibility and view of the river made the waterfront much less attractive than the touristy shops nearby.

Because the waterfront deck is spatially higher than the inner streets surface, the river is not visible unless people stand right on the edge of the waterfront. However, the only program on the waterfront deck is 4 empty tents, which makes the waterfront even less appealing.

DESIGN PRINCIPLE

“A BALANCED TRI-CIRCLE”

Activity Transition

Maintain and reinforce the structural value, so the waterfront continues carrying the infrastructures and buildings for human use and can better prevent future flood risks.

ECOLOGICAL SOCIAL STRUCTURAL

Maximize the potential ecological value of the waterfront and turn it to a platform for stronger species interaction.

Enhance the social value of the waterfront to provide activity space for various social gatherings.

The climbing net design is inspired by the role of Old Sac as an industrial and river transportation center. It is a dynamic reimagining of the harbor industry.

The new decking structure will be built on the existing supporting piers of the bank. It extends the pedestrian circulation closer to the water where the view has the least obstructions. A net structure will be added between the old and new decks, which provides interactive recreational space for users. It defines a new way for human-river interaction.

RIPARIAN MARSH

The organic shape riparian landscape will turn the undesirable constant change of water level to advantage by creating rich and fertile marshland along the waterfront.

The current underground stormwater system pumps the water directly up to the river at the waterfront because the elevation of the city is lower than the river during flood season.

MARTINEZ, CA FALL 2020 GRADUATE ACADEMIC PROJECT (INDIVIDUAL) LANDSCAPE ARCHITECTURE DESIGN INSTRUCTORS: KRISTINA HILL, DENI RUGGERI

PROJECT STATEMENT

Martinez is a small city in Contra Costa County, yet it is almost at the east edge of the bay area. Because of its location and topography, the city seems different from our common view of the bay. It does not have so many glorious characters that the bay area has but shares a lot of the bay area’s problems. In this project, a city scale upgrade was proposed to tackle the current issues that Martinez has.

Martinez, in 2050, will be a healthy city.

The city will provide its residents a healthy lifestyle. The old industrial site will be eliminated and replaced by new affordable housings. As the source of pollution disappeared, the life expectancy will significantly increase. Green space will be easily access by all. The fire risk will also decrease as the implementation of firebreaks.

The wind and solar will provide consistent sources of energy for local consumption. The daily excess energy will be stored in the flywheel power storage plant in the case of when wind/solar energy is not accessible or during a power outage. An estimate of 98,550 MWH Energy will be contributed to the state utility grid annually.

KAILUA BAY: THE EPITOME OF HAWAII A DISASTER BASED RESEACH

OAHU, HI SPRING 2021

Kailua Bay on the east side of Oahu Island. Unlike Waikiki, this part of the town is more for the locals. Because of the unique landuse in this region, Kailua Bay is like the epitome of the Oahu island. In this project, I want to reveal the challenges that Hawaii is facing through the lens of Kailua Bay.

DESIGN WORKSHOP PROJECT (GROUP) LANDSCAPE INSTALLATION DESIGN COLLABORATORS: BRISA ALVARADO, AMERITA SINGH, JESSICA FAHMY, BOWEN HUANG, SARA LOOTAH, ARIANA SHEVCHUK INSTRUCTORS: CLAIRE NAPAWAN, BRETT SNYDER

PROJECT STATEMENT

In the project, we worked as part of the UC Davis branch of Resilient By Design to create installations as a tool to educate the public about the sediments and fish habitats along the Alameda Creek.

In 9 weeks of the time frame, we started with site visits, sediment research, and booklet design in groups of two. Later, we, as a bigger group, came up with a final design to showcase our research after 2 weeks of brainstorming.

ALAMEDA CREEK TOPO SECTIONS

MODEL MAKING PROCESS

After built several mini prototypes, we decided to laser cut topo sections on plywood and glue them together with equal gaps in between. This enables us to achieve a sense of volume by using minimal materials.

DESIGN DEVELOPMENT

We wanted our installation to have a sense of volume to show the topography, while cost and buildability were also things we have to consider.
