I might have it wrong in the inside/outside city limits with respect to parking on the curb as there are differences. There are also municipal rules but in general they are only for very specific locations afaik.

If you get injured because the municipality refused to act they are on the hook. Thell them you want it on paper they say they will do nothing to prevent this and you want them telling you specifically you have to walk on the street because they do not act on illegally parked cars.

Edit: where I live I have the option of specifically reporting a dangerous situation which in your case I would: near school zones with children involved it always is in my opinion but who am I to judge. It also helps if more people complain. We have a load of parking tourists here since the municipality mode the payed zones so more traffic and more annoyances. My first messages got impolitely unanswered but after a year of complaining by pretty much everyone they finally start doing things.
