if it is outside the city limits, the actual city of pittsburgh workers are not allowed to go there unless the municipality requested their help. each municipality probably has their own procedures and may have contracts with the city that might allow the city employees to help, but without some sort of legal “okay,” they can’t do anything. i do think most neighborhoods around pittsburgh have multiple entities to clear their roads though just as you said! i just only know the city rules and what family members have experienced :)
