ROW is always wider than the street.
If a 50 foot wide ROW has a 26 feet wide street, then there would be an area 12 feet wide behind the curb on both sides of the street which is city owned. Property owners should not encroach upon public ROW with fences and walls as this conflicts with the use of ROW for utilities. The revenue is collected by the state as a gasoline tax. The money is distributed back to local government in accordance with a state legislature determined formula. The miles of streets or conditions of those streets have no bearing on the amount of RUTF distributed to cities.
