The city can provide rights to install EV chargers on the street to private companies for free, in exchange for a share of the revenues. In Europe almost all EV chargers are run by companies vs governments - which they must see as a for-profit investment, as they are for-profit companies -, so if it works here, there's no reason why it can't work there too. The revenue the city receives from EV charging can be used to improve public transportation, so everybody wins.

Don't forget EVs are beneficial for everyone in terms of less pollution, so cities should be encouraging residents to purchase EVs over ICE with small incentives (in my city you don't need to pay for street parking).
