Developers submitting proposed subdivisions and conditional use developments to municipal and county planning agencies shall be required to obtain approval of street names through the county addressing division, before final plat approval, to ensure that the proposed names do not duplicate other names in the county. At such time that a subdivision or conditional use street name is approved, the developer shall send a copy of the letter of approval to the appropriate municipal or county planning and development agency for their records on the development.
General principles of street naming are applied in the following regulations and standards with the purpose of eliminating "critical duplication," "phonetic name duplication," and the excessive use of "subsidiary name duplication" of street names. These regulations shall be enforced to eliminate confusion, establish continuity and develop countywide uniformity according to the official street maps of governing entities of the county. The county addressing division acknowledges that municipalities may stipulate additional requirements in their name review process.
All proposed public and private street names and types must be approved by the county addressing division at the time the plats are under final review by the respective municipal agencies. All final plats submitted to the county recorder shall be stamped "STREET NAMES AND ADDRESSING APPROVED," dated, signed or initialed by the representative who coordinated the approval of the names and addressing.
When it is necessary to change the name or type of an existing public or private street, the street name and type or number and the corresponding intersection coordinates must be approved by the county addressing division to eliminate confusion and duplication with other streets in the county.
When there are two or more streets of the same name within the geographic boundaries of the county, the city and county governing bodies, by ordinance and without petition, may change the name or type of any such street in their jurisdiction, so as to leave only one to be designated by the original name. The ordinance shall be recorded with the county recorder’s office.
When a city or county governing body determines to change the name of a street, it should schedule a public hearing to convey information about proposed name changes to citizens who are affected, and to eliminate capricious actions.
No duplications of street names or numbers used as names within the boundaries of the county shall be approved.
These are duplications of identical names and street type designators on two or more streets which may or may not have overlapping frontage number ranges regardless of the directional of either the street or the frontage numbers.
These are duplications of identical names on two or more streets, but with different street type designators; not to include valid subsidiary duplications.
These are duplications of street names which have duplicate or similar pronunciations, but are spelled differently.
Subsidiary Name Duplications may be approved within the municipal jurisdictions for which the streets are located. Conditions which allow approval of these duplications are:
City and county governing bodies may change street name duplications in their jurisdictions without petition when it is determined that the change is in the public interest. Arbitrary or capricious street name changes shall not be made.
Street names with historical significance should be retained, whenever possible, over other names when considering elimination.
In determining whether to change a street name the governing body may consider the following:
The number and types of buildings which will have their addresses changed;
The length of time the name has been in use;
The length of the street and the amount of traffic
Compatibility with adjacent streets.
Intermittent street name duplications. The continuity of a street may be maintained so that it can continue with the same name along its entire length overcoming barriers such as rivers, canals, railroad tracks and undeveloped voids. If a street is interrupted by these features the following conditions shall apply:
If the street continues immediately on the same bearing beyond the barrier and is within line of sight, it may continue with the same name.
If a street is on the same bearing and its point of continuance beyond the barrier is beyond line of sight, it must be renamed to avoid duplication.
Any street which terminates in a cul-de-sac turnaround is considered to have established an end and cannot continue with the same name on the same bearing.
If a street is terminated by a void of unimproved land and it continues on the same bearing beyond the void, it may continue with the same name. Such a street is a “stub street” and must be required to make a connection when the void is developed.
Intermittent streets with duplicate names that currently exist and were dedicated in any municipal jurisdiction prior to the effective date of this title and are in contradiction to the above conditions, may be exempted or changed by the authorities in that jurisdiction.
Persons may petition their governing city or county governing bodies to change, by ordinance, the name of a street which fronts upon lots and land parcels which they own. Procedures to change a petitioned street name should include a public hearing and ordinance to make the change.
Street names must meet subjective criteria before final approval can be given. These criteria should take into consideration historical character, local color or theme, locational characteristics, and compatibility with adjacent streets.
Compatibility and continuity of all proposed streets with adjacent streets to which they are connected or may become connected implies they should continue with the same name or street number if they are on the same bearing. In all other cases the following criteria shall apply:
When a proposed minor street intersects a collector street, the proposed name shall maintain continuity with any existing street across from the collector street when both are on the same bearing.
When a proposed minor street intersects a major collector street such as controlled access highway, expressway or parkway, it shall not maintain name continuity with minor or collector streets on the same bearing which are across from the major collector street.
A proposed minor street or collector street shall not maintain name continuity across either of the major baseline or meridian streets (e.g. Main St and South Temple St in Salt Lake County).
A proposed collector street may maintain name continuity with other collector streets across major collector streets when they are on the same bearing.
Continuity shall be maintained on intermittent streets as defined in section 4.3.6.
All streets which are assigned a street number must maintain continuity along the same bearing regardless of their intersection with major and secondary collector streets or by interruptions with physical barriers. Street numbers should conform to the frontage scales applied in the Township and Range sections for which they are located.
Converting numeral designation to alphabetic names. Streets may be assigned alphabetic names with numeric value (i.e. Second Ave, a numerical name). The Arabic equivalent (200) or alphanumeric mix (2nd) shall not be used when issuing official situs addresses or in any other address format. Further, alphabetically converting street numbers to numerical names should be discouraged and approval given on a selective review basis only.
Prohibited Naming Conventions. In accordance with the goal of minimizing confusion for street names containing locational and other characteristics, the following criteria shall apply:
The four compass directions shall not be used as part of the street name (e.g. Eastwood). This is to eliminate the occurrence of double directionals in assigning the address (e.g. 1229 W. Eastwood Dr).
The standard street type designators shall not be used as part of the street name (e.g. Springlane Rd). This is to eliminate the occurrence of double street type designators in the address.
Abbreviations of part or the entire street name shall not be allowed.
A proposed street name using both the given and surname of a person shall not be approved except by petition to the city or county governing bodies who have jurisdiction in the area where the proposed name is made.
Street Name Length. The length of a street name shall not be more than 13 characters including one space and two words, but not to include the street type designator.
When streets are proposed, they shall be given a “street type designator” corresponding to certain physical and functional characteristics of the street. The following are the only designators which are standard and must be applied as follows:
Major collector streets with planted or other physically separate medians.
A meandering, curvilinear or diagonal street usually longer than 1000 feet and most always connected to other rights-of way.
Limited streets that may run in a direction, are most always longer than 1000 feet and usually connect with the United States or Utah State primary highways.
Straight streets matching principally the axes of the countywide grid system.
Short collector or minor streets which are usually less than 1000 feet in length and may not always connect other right-of-ways. May be used in names for private rights-of way.
Permanent dead end streets or cul-de-sacs streets usually less than 600 feet in length and containing three (3) or more lots or separate dwelling structures. May be used effectively in planned unit developments, condominiums or other conditional use developments where streets with short branching configurations are proposed.
Designations reserved for high density commercial developments with multiple structures and occupancies that can be substituted for the street type designator in an assigned address. When commercial development type designators are used in the address format, the street name is also substituted with the development name.
A street shall not be assigned both a name and a number. This is to avoid persons using both interchangeably with their official situs address. If a street is designated with an alphabetic name, only its intersection with other streets are assigned numbers as coordinates for the purpose of displaying them on intersection signs.
Streets that change direction at oblique angles to the countywide grid system axes.
Streets that are diagonal to the countywide grid system axes. Any street which has intersection coordinates that shift more than five numbers along its entire length constitutes a diagonal street.
Cul-de-sac streets which intersect at right angles to other roadways. "bubbles” or “pockets” (which are not true cul-de-sacs) with four or less lots shall be named and numbered sequentially along the principal street with which they are configured.
Circled or looped thorough-fares which return to them-selves. If frontage numbers to be assigned for addresses on buildings are all on the outside of the loop, or all on the inside of the circle, the street may be given a single name, otherwise, a break shall be made at a distinct point at the back of the loop and multiple names assigned. This is to avoid duplicate and parallel address ranges for the same street name.
Horseshoe shaped thorough-fares that are not in alignment with the countywide grid system shall be assigned at least two names with the breaks occurring at the most distinct bends on the street.
Curvilinear or meandering streets which have coordinate changes at their intersections. Frontage number ranges should never overlap if a street meanders, otherwise two or more names shall be assigned with a break at a distinct bend or intersection which will eliminate the duplication of numbers.
Dead end streets which are not considered intermittent or will not likely be extended.
Private streets which are proposed within private developments such as condominiums and planned unit developments shall be named.
Major collector streets and collector streets which follow Township-Range section lines or are parallel to the axes of the Countywide Grid System, and then change direction at oblique angles to the grid axes to which they are aligned
Streets which shall be assigned numbers:
Major collector streets or collector streets which are in continuous alignment with the Countywide Grid System axes or with Township-Range section lines, other than U.S. or Utah State Highways, shall be assigned street numbers.
Marginal access streets which parallel major collector streets and collector streets in alignment with the Countywide Grid System shall be assigned numbers.
When calculating street numbers and intersection coordinates, all numbers shall be measured to the centerline of the roadway (except in Salt Lake City) and must have the last digit of the number rounded up or down to end in either a “0” or a “5”.
Streets which may be assigned alphabetic names or numbers.
All streets which are not cul-de-sac streets, dead ends, or in private developments, and are aligned with the Countywide Grid System axes may be assigned an alphabetic street name or a street number, but not both.
Dead end streets which are “stub streets” planned for future connections, may be assigned a name or a number, providing continuity with the connecting street is maintained.
Assignment of street numbers should be encouraged over assigning alphabetic names to streets which are in alignment with the countywide grid system.
Street name signs shall conform to the design specifications and in the number provided by the standards and regulations established by local governing entities in their jurisdictions. Uniformity in public street signs should be maintained.
Private rights-of way which have been assigned an alphabetic name and intersect with dedicated public streets shall be designated as a private street with a “blue” intersection sign conforming to the standard specifications mentioned above. Developers requesting standard street signs within their developments shall have them constructed with the “blue” designated color for private streets.
Signs constructed for alphabetic named streets shall display both the name, street type, and corresponding intersection coordinates.
