Redwood port starts wharf upgrade

   The Port of Redwood City in the San Francisco Bay said it’s started pile driving for the reconstruction of two wharves.
   “Demolition of the old wharves and adjacent warehouse, dating back to the 1940s, has nearly been completed,” the port authority said.
   The new, “seismically designed,” concrete wharf, 425 feet long by 70 feet wide, will be supported by 113 concrete pilings. Pile driving will be completed before the end of the year.
   The port said it experienced a 51 percent increase in cargo movement across its docks for the fiscal year 2011-2012, ending June 30, related to construction in the Bay Area and building materials coming from British Columbia. The 12-month figure was 1,319,198 metric tons, up from 871,940 metric tons from the previous fiscal year and the highest at the port since 2008.
