SAN FRANCISCO (AP) – California water officials say the state has not yet made any final decision on scaling back the size of a troubled water project. State water officials filed papers Friday saying they were considering cutting immediate plans for a $16 billion project to carry Northern California southward from two tunnels to one, with the second tunnel postponed indefinitely. They asked state builders vying to build the project to submit proposals on the pared-down one-tunnel project. California natural resources spokeswoman Lisa Lien-Mager says no decision has been made on changing the project. Another state water agency whose approval is needed for the project, the state Water Resources Control Board, says It is watching the state’s negotiations with water contractors for a possible scaled-down project. Board spokesman Tim Moran says the board will consider whether any cuts in the project size require changes to the state approval process. The tunnels would be the state’s largest water project in decades, redoing the state’s north-south water deliveries.
