There is a high probability that a Loma Prieta magnitude or greater earthquake will shake the Bay Area during the projected 18-year redevelopment of Treasure Island. However, city development officials say the island will ultimately be safer than the liquefaction-prone areas of downtown San Francisco and the Marina.

Most of Treasure Island will be inundated by the end of this century, if the documented progression of the ocean’s rise caused by climate change continues as predicted. Studies foresee sea-level rise ranging from as little as five inches to as much as six feet. The lowest parts of Treasure Island lie just four feet above the Bay’s low tide.

The Treasure Island redevelopment, which aims to be the most ecologically sustainable community in the world, delivers a positive self-image of San Francisco as a forward-looking, avant-garde, socially and environmentally responsible metropolis. Nothing excites the utopian impulse more than a blank slate — and Treasure Island’s 486 acres have been semi-abandoned since the Navy shut down its base in 1997.

When completed, the new east span of the San Francisco-Oakland Bay Bridge will be not only the most complex engineering feat in California history, but also the most expensive, with a cost never subjected to public scrutiny. Although today’s price tag stands at $6.3 billion, the figure accounts for only salaries and hard materials—things like concrete and steel and cranes. When all is said and done, the new Bay Bridge will wind up costing tax- and toll-payers more than $12 billion—a figure that leaves even the officials in charge “staggered.”
When all the pieces are finally welded together and tethered by the main suspension cable, the Bay Bridge east span will be not just a new American icon, but also a truly global monument. From the enormous solid steel castings of cable saddles, brackets and bands being forged in Japan and England to the gigantic bearings and hinges being manufactured in South Korea and Pennsylvania, fabrication of the bridge is under way in seven foreign countries and in more than two dozen American cities, including 12 in California.
Overall cost estimates have been presented to the public in annual reports and press briefings, but the cost of interest on money borrowed to pay for construction has not been included.

The Bay Area Toll Authority has the unique power to raise bridge tolls without the Legislature’s approval, which it has done repeatedly to pay off the $6.9 billion bond debt amassed so far to build the new Bay Bridge and upgrade six other spans. That makes BATA particularly attractive to Wall Street, which has pocketed more than $122 million in fees to arrange the borrowing.
