Six years! are you kidding me! This is not ROCKET SCIENCE! Mechanized Equipment can lay about a half a mile of track a day. Working 5 days a week to do 70 miles is around 175 days to complete the track work. Depots at Cloverdale, Windsor, Santa Rosa and Petaluma are done. A maintenance facility, bridge work and the other stations would be done concurrently with the track and other infrastructures. Engineering has been ongoing since SMART was formed. The EIR has addressed the snakes and such and no permitting is required WITHIN the ROW. Fish and Game and other agencies are already on board. We are not re-inventing the wheel here. or maybe we are and SMART hasn't told us yet! Ribbon rail and ties are off the shelf and available almost immediately. Six years? Only if SMART has a construction schedule that is very lame and starts several years after the November ballot. Costs will continue to rise while commuters are stalled in 101` gridlock paying $5 a gallon gas!
