I'm an engineer at Code for America - https://www.codeforamerica.org/ - a non-profit that does this kind of work with cities, counties, and states.
Its still pretty early days for civic technology. I think we'll see tech provide all the services you listed, eventually. It'll probably be a mix of outside vendors and local governments running their own engineering teams. There are still some legal barriers in the way, procurement for example.
Its happening, just slowly.
If you are interested in speeding up the progress of your city, I'd recommend checking out if there are any civic tech volunteer groups near you. https://www.codeforamerica.org/brigade/
