Zoning Ordinance 63.520 prohibits obstructions over 2 1/2 feet high to be located in the traffic visibility zone, the area adjacent to intersecting streets, and also the area next to driveway entrances.
City Ordinance 45.08 states that signs are prohibited on public property and on public right-of-ways including boulevards (the area between the public sidewalk and the street). If there is not a sidewalk in place, the average boulevard is 15 feet from the edge of the roadway. Most open ditches parallel to roadways are in the public right-of-way.
