Notes:
Now the FAA and SFO have considered a variety of alternatives to improve the operational efficiency of the airfield to address existing poor weather delay problems and projected future air travel demand. This technical report looks at those alternatives that would re-configure the runways and result in the construction of new runways, runway extensions, and runway safety areas in the Bay. Alternative A-3 here would construct a new 1028 runway in the Bay and have a taxiway connecting that new runway to the existing airfield. It would also construct what are called runway safety areas at the end of the existing 119 and 1028 platforms. Alternatives BX-6 and BX Refined, or BX-R, would also have this new 1028 runway and would separate the 119 runways, with alternative BX-R, one of the 119's extending further into the Bay than on Alternative BX-6. In all three of these alternatives, the new 1028 runway could be built either on fill or on pilings. The other runways, runway extensions and safety areas, would have to be built on fill to avoid interfering with Air Field operations during construction. Therefore, our technical report looked at a total of six reconfiguration alternatives, these three reconfigurations built either all on fill or a combination of fill and piles, termed the "Hybrid Alternatives."
