Seven years ago, a $100 million deal by the federal and state government to purchase 16,500 acres of industrial salt-evaporation ponds along the southern shoreline of San Francisco Bay made national news. It was to be the biggest wetlands restoration ever attempted in the West, an opportunity to bring back fish, birds, harbor seals and other wildlife to levels not seen in perhaps a century. But then came years of scientific studies and public meetings. On Tuesday, the follow-through took shape atop the earthen levees south of the San Mateo Bridge near Hayward, as 20 massive dump trucks moved piles of dark soil, and excavators reshaped the landscape while white pelicans and egrets drifted through breezy blue skies above it all. "This is the culmination of all the work we have been doing. This is what we've been waiting for -- dirt being moved, bay waters coming back," said John Bourgeois, manager of the South Bay Salt Pond Restoration Project. The work on the shoreline at Eden Landing is a microcosm of the overall bay restoration effort. It began in July and is scheduled for completion in two years. The project aims to restore to tidal marsh 630 acres of former industrial salt evaporation ponds that were once used to concentrate salt for roads, food and medical uses. Over an area roughly the size of 600 football fields, workers in hard hats and orange vests are reshaping and taking down levees that now are 8 to 10 feet tall. Next summer, bay waters will pour into the landscape, which in the 1800s was a rich mix of marshes and sloughs. Today, that area looks like an arid, whitish moonscape. In some areas, crews will break thick crusts of gypsum up to one foot deep left from Cargill's old salt operations, to allow plants like pickleweed, native spartina and alkali heath to grow back more quickly.
