It is not permitted to attach signs advertising sales to telephone poles, utility poles, or street signs. Signs are not permitted to be placed in any public right-of-way. This includes the "common area" between the street and sidewalk and in street medians. Typically, right-of-way extends 11' inward from the curb. Signs should not be displayed so they impede traffic visibility in any way. Be sure to acquire permission from the adjacent property owner before putting any signs on the property.
