SacRT is holding community open houses on the Green Line to the Airport in early December. December 1 in North Natomas, December 2 in Sacramento, and December 3 in South Natomas. Details are at http://www.sacrt.com/glopenhouse.stm.
As I’ve written before, I don’t think that an extension to the airport makes economic sense, with likely low ridership and high costs to get to the airport. But there are real opportunities for South Natomas, which is very much underserved by public transit.
I encourage you to attend one of the open houses, make your own decision, and then get involved to make sure that SacRT makes decisions that support transit access for lower income communities and economic development, connecting jobs to homes.
