I salute you for contacting your government reps. A lot of the members of this site are modelers so that's why I asked. I've advocated many times that members of this site do the same as some do not have the experience of doing so.
SMART's success (so far at least) has triggered a lot of interest in the renovation of passenger rail in your area to alleviate growing traffic gridlock. I live in Palo Alto and without CalTrain our freeways would be gridlocked.
As I travel up there frequently my interest is to see the line extended into Healdsberg and on to Cloverdale where that city built a brand new station for SMART.
