Treasure Island Community Development, the partnership between Lennar Corp. and Stockbridge/Wilson Meany, announced today that its plans for redevelopment of Treasure Island and Yerba Buena Island in San Francisco has been awarded LEED-ND Platinum plan certification, the highest designation possible for green, sustainable development.

The LEED (Leadership in Energy and Environmental Design) rating system, which was developed by the U.S. Green Building Council (USGBC), is the foremost program for buildings, homes and communities that are designed, constructed, maintained and operated for improved environmental and human-health performance. LEED-ND is used to assess the design and performance of entire neighborhoods.

Treasure Island is one of the highest-scoring LEED-ND projects ever, according to the USGBC. It also is the largest plan, in terms of acres, to receive the LEED-ND Platinum certification.

"Treasure Island's LEED-ND Platinum certification demonstrates tremendous green leadership that will be recognized globally,'' said Rick Fedrizzi, CEO and founding chair for the USGBC. "With its plan, Treasure Island has responded proactively to the most important challenges of our time, including global climate change, dependence on non-sustainable and expensive sources of energy and threats to human health. Congratulations on this outstanding achievement.''

In addition to achieving one of the highest scores for a LEED-ND project, Treasure Island's plan recorded other milestones:

It is the largest development, in terms of acres and building square footage, certified under LEED v4.
Of the LEED-ND projects globally, it is one of just 17 to be certified at the Platinum level.
"At the outset of our planning, we committed to developing a sustainable community that utilized the latest innovations in infrastructure, housing and transportation,'' said Chris Meany, principal of developer Wilson Meany. "We are thrilled that Treasure Island has achieved the highest designation ever. It is only fitting that this milestone has occurred in San Francisco, a city at the forefront of environmental consciousness.''

Treasure Island received Platinum LEED certification for implementing measurable strategies and best practices to achieve sustainable site development, water savings, energy efficiency, sea-level rise adaptation and overall environmental quality.

"This is an iconic, historic property and we are committed to ensuring that it sets a global standard for sustainable development in the 21st century,'' said Kofi Bonner, president of Five Point/Northern California, which is managing the development of Treasure Island on behalf of Lennar. "This certification is a testament to our commitment.''

The plan for Treasure Island/Yerba Buena Island received high marks for its overall design of compact, walkable neighborhoods, an array of housing types, and its reduced dependence on automobiles. One in four homes at Treasure Island is slated to be affordable. Transportation improvements will include a new intermodal transit hub, with a ferry terminal that supports ferry service between Treasure Island and San Francisco.

Redevelopment of Treasure Island, a man-made island created for the 1939 World's Fair, was approved unanimously by the San Francisco Board of Supervisors in 2011 and includes the upgrade of infrastructure such as roads and utilities and the creation of 300 acres of parks and open space.

Last May, the U.S. Navy officially conveyed 290 acres that comprise all of the U.S. Navy lands on Yerba Buena Island and approximately half of its land on Treasure Island to the Treasure Island Development Authority, the public benefit authority administering the property. The Navy also turned over 518 acres of submerged land surrounding the islands. Treasure Island and Yerba Buena Island was home to Naval Station Treasure Island until its closure in 1997.

Treasure Island will have two residential neighborhoods, one along the western edge looking back to the city, and a second stretching to the east from Clipper Cove with a view of the Bay Bridge and East Bay hills. The new neighborhood on Yerba Buena Island will be built on existing development areas around the top of the island, surrounded by its vegetated slopes.

The mixed-use, high-density project is approved for up to 8,000 homes (2,000 affordable), approximately 200,000 square feet of retail space, 300,000 square feet of office and commercial space and up to 500 hotel rooms.

Infrastructure work began earlier this year on Yerba Buena Island, the natural island adjacent to Treasure Island. Work on Treasure Island is expected to begin this September.
