If a residential zone borders or runs along a public or private street with a different zone or subzone of lower residential density or larger minimum lot size placed behind it, a second appended code may be added to that zone or subzone to designate the depth of the zone in feet from the right of way line of the street. If no depth is specified, the zone will be assumed to border a property line, road, major geographic feature or a section, quarter section or quarter-quarter section line, or other legally surveyed boundary. This depth code may only be used in some instances on the official zone map to help clarify certain zone district boundaries. (Ord. 13-01, 9-3-2013)
