Treasure Island

From San Francisco Wiki

Treasure Island is a man-made island located in the San Francisco Bay, California. Created for the 1939 Golden Gate International Exposition, it has undergone numerous transformations, from a world’s fair site to a naval base, and is now undergoing significant redevelopment as a mixed-use community. Its history is intertwined with the growth and evolution of San Francisco itself, and it continues to be a focal point for development and debate.

History

The idea for an artificial island in the bay dates back to the early 20th century, initially proposed as a potential airport site. However, the concept gained traction with the planning for the 1939 Golden Gate International Exposition, a world’s fair intended to celebrate the completion of the Golden Gate Bridge and the Bay Bridge. Construction began in 1936, utilizing materials dredged from the bay floor and the construction of a perimeter of rock and concrete. The island’s creation involved a massive engineering undertaking, reshaping the landscape and creating a platform for the exposition’s grand structures. [1]

Following the exposition’s closure in 1940, the island was taken over by the United States Navy and became Naval Station Treasure Island. For over 50 years, it served as a key naval facility, playing a role in World War II, the Korean War, and the Vietnam War. The naval base was officially closed in 1997 as part of the Base Realignment and Closure (BRAC) process. The subsequent transfer of the land to the City and County of San Francisco and the State of California initiated a complex process of environmental remediation and redevelopment. The Navy retains responsibility for ongoing cleanup efforts related to historical activities on the island. [2]

Geography

Treasure Island covers approximately 400 acres, situated between Yerba Buena Island and the city of San Francisco. It is connected to both by the Bay Bridge. The island’s topography is largely flat, a result of its artificial construction. However, the views from Treasure Island are notable, offering panoramic vistas of the San Francisco skyline, the Bay Bridge, Alcatraz Island, and the surrounding bay waters. The island’s location exposes it to significant wind and fog, typical of the San Francisco Bay Area climate.

The soil composition of Treasure Island presents unique challenges. Constructed from bay mud and fill, the ground requires ongoing stabilization and remediation efforts to address potential seismic risks and environmental contamination. These challenges have influenced the design and construction of new buildings and infrastructure on the island, requiring specialized engineering solutions. The island’s proximity to the water also necessitates careful consideration of sea-level rise and potential flooding impacts in future development plans.

Economy

For decades, the primary economic driver on Treasure Island was the naval station, providing employment for military personnel and civilian workers. Following the base closure, the island experienced a period of economic transition. The current redevelopment plan aims to transform Treasure Island into a vibrant mixed-use community with a diversified economy. This includes residential development, commercial spaces, research and development facilities, and hospitality services. [3]

The Treasure Island redevelopment project is anticipated to create thousands of jobs during construction and in the long term. The plan emphasizes attracting businesses in sectors such as technology, life sciences, and renewable energy. The island’s location and accessibility are seen as advantages for attracting companies and residents. The project also includes provisions for affordable housing, aiming to create a diverse and inclusive community. The economic success of the redevelopment is dependent on addressing the challenges of infrastructure development, environmental remediation, and transportation access.

Attractions

While still largely under development, Treasure Island offers several attractions. The views from the island are a significant draw for visitors, providing unique perspectives of the San Francisco skyline and the bay. The Treasure Island Flea, a monthly outdoor market, features vintage goods, art, and food vendors, attracting a diverse crowd. [4]

As redevelopment progresses, new attractions are planned, including parks, open spaces, and cultural facilities. The island’s waterfront location offers opportunities for recreational activities such as sailing, kayaking, and biking. The historic buildings from the 1939 exposition, while limited in number, serve as reminders of the island’s past. The ongoing transformation of Treasure Island is itself an attraction, with visitors observing the progress of the large-scale development project.

Getting There

The primary access to Treasure Island is via the Bay Bridge. Several on- and off-ramps connect the island to San Francisco and the East Bay. Public transportation options include Muni bus routes that serve the island, providing connections to other parts of the city. Bicycle access is also available, with dedicated bike lanes on the bridge and on the island.

Traffic congestion on the Bay Bridge can be a significant factor during peak hours, impacting travel times to and from Treasure Island. The Treasure Island Mobility Management Program aims to address transportation challenges through strategies such as promoting public transportation, encouraging carpooling, and improving pedestrian and bicycle infrastructure. Future transportation improvements may include enhanced ferry service and potential expansion of public transit options.

Neighborhoods

Currently, Treasure Island does not have formally defined neighborhoods in the traditional sense. However, the redevelopment plan envisions the creation of distinct districts with unique characteristics. These districts are planned to include residential areas, commercial centers, and open spaces, each with its own identity. The plan emphasizes creating walkable and bikeable neighborhoods with a mix of housing types and amenities.

The redevelopment is divided into several phases, with each phase focusing on the development of specific areas of the island. Early phases have concentrated on infrastructure improvements and the construction of initial residential units. As the project progresses, new neighborhoods will emerge, contributing to the overall transformation of Treasure Island into a thriving community. The design of these neighborhoods incorporates principles of sustainable development, aiming to create environmentally friendly and resilient communities.
