San Francisco Shipyard and Candlestick Redevelopment — $8 billion

Redevelopment of the San Francisco Shipyard and Candlestick neighborhoods began in 1999, when the city chose Lennar Urban as the master developer.

Though the projects are near each other, they are located in two different waterfront spots, south of downtown San Francisco.

The company's plan is to transform the areas near Candlestick Park and the polluted former naval base into new housing developments. Spanning 775 acres, the entire redevelopment will cost $8 billion and add 12,100 housing units — nearly a third of which will be offered below-market-value. In addition, the SF Shipyard and Candlestick sites will feature 3 million square feet of office space and 350 acres of public space at full build-out.

As of April 2016, there are more than 200 residents living in five of the new Shipyard buildings, with more to come. About 6,000 housing units will be complete there by 2028, according to the San Francisco Business Journal.

Set to begin in some time in 2017, construction of the Candlestick's first phase will include over 2,200 residential units, nine acres of parks, and over a million square feet of commercial space. An exact timeline for the five-phase development has not been announced, though Lennar has said it expects construction to "take decades."
