As revenue increases, city services can be expanded. Schools on the other hands are basically crooks as far as I can tell. The reason being that I have yet to get the Fremont Union Highschool District to offer up actual budget numbers and actual spend. They will argue all sorts of things about "confidentiality of teacher salaries" or "we're not a government so we don't have to give you that information." but generally I have not been impressed with the way they operate.

Traffic and parking is a legitimate concern. Traffic has gotten worse again (after getting better after the dot com crash). But many programs are targeted at making the city more bike accessible for easier access.

For parking, Sunnyvale is indeed surprisingly bad. For a sleepy town with nothing to do you often can't get parking downtown.
1. Considering that some of the apartment dwellers will become homeowners and their place will be taken by new apartment dwellers, how will the overcrowded schools support the influx?
2. Considering people will take public transit to go to work, they still would use cars to move around locally in the area on evenings and weekends. How will the current streets support the greater density of cars? e.g. Central Expressway used to be an expressway now it is a parking lot.
3. Overburdened police and firemen will be exposed to further strain.
4. Parking is a nightmare not just on residential streets but even at local establishments. Space needed for parking is used to build more housing.
Unless you live here and face these issues it's easy to downvote rather than come up with solutions that are at pace with the housing construction boom.
If I paid over a million dollars to buy a house in a school district that has a good score what would you suggest I do when suddenly the student to teacher ratio is so skewed that the education of my children suffers?
