2.0 Definitions

The following terms used in this policy shall have the meanings set forth:

Address (situs address)

A unique alphanumeric descriptor which identifies the property location of a parcel of land, building or other structure on the Countywide Grid System.

Address certificate

The official document, including a certificate number and the registration of a legal situs address, issued to the owner or resident for their parcel, building, or other structure.

Address format

The order and structure of the five standardized components used in the situs address (frontage number, directional, street name or number, street type, sub-structure suffix) (e.g. 4877 S 4980 W #101 or 1310 E Vine St).

Baseline street

The east and west directional street (South Temple Street in Salt Lake City, Salt Lake County) which intersects with the Meridian Street to benchmark the permanent origin of the Countywide Grid System and provides a point from which all other streets and legal situs addresses are calculated (see “Meridian Street”).


A high-density development with groups of architecturally unified structures containing commercial establishments focusing on a plan of integrated business activity and providing internal circulation of traffic. The term “Center” may be substituted for the street type component in the standardized address format.

Collector street

A street which carries traffic from minor streets to the major street system, including the principal entrance streets of residence development and the primary circulating streets within such a development.

Common name duplication

Duplications of identical names on two or more streets, but with different street type designators; not to include valid subsidiary duplications (e.g. Dusk Ln and Dusk Dr).


The identification characteristics of a street which are maintained uniformly along its entire length including the street name or number.

Countywide grid system

The east/west axis and north/south axis coordinate system which has developed over the greater part of Salt Lake County to identify address and street locations.

Critical duplications

Duplications of identical names and street type designations on two or more streets which may or may not have overlapping frontage number ranges regardless of the direction of either the street or the frontage numbers.

Cul-de-sac street

A minor street having one open end and being permanently terminated at the other end by a vehicular turnaround.

Dead end street

A street which may or may not be permanently terminated and does not provide access to any other rights-of-way and must be entered and exited from the same point.

Diagonal street

A street which has its bearing at an oblique angle to the established direction of the Countywide Grid System and which has intersection coordinates that shift more than five numbers along its entire length.


The compass direction of the legal situs address which references the Countywide Grid System and the direction in which the frontage numbers are measured along the roadway of both public and private streets. When a street number is used in the address, instead of an alphabetic name, a directional is also used to designate its direction. A directional is always abbreviated with the first letter of its compass direction in standardized address format.

Final plat

A map or chart of a subdivision, PUD, condominium, or other proposed development which has been accurately surveyed, and such survey marked on the ground so that streets, alleys, blocks, lots and other divisions can be identified.

Frontage number

The prefix component of the legal situs address which is numerically sequenced and assigned to a structure or parcel along a street according to its relative distance from the intersection of the baseline street and meridian street, perpendicular to the baseline or meridian axes of the Countywide Grid System.

Frontage scales

A system of measuring frontage numbers along streets according to a ratio of numbers per rod or half mile distance (i.e. 400 numbers/2640 feet or two numbers/rod). Application of the different frontage scales allows elongation or compression adjustments to smooth the Countywide Grid System.


A state or federally designated street for the conveyance of high volume vehicle traffic.

Intermittent street name duplications

Duplications of identical names and type designators on streets which end and then resume at a further point where they overcome barriers such as rivers, canals, railroad tracks, or undeveloped voids.


The point on the Countywide Grid System which identifies the location where two or more streets cross one another.


An architecturally unified group of commercial establishments built on a site which is planned, developed, owned and managed as an operating unit and requires property identification according to sub-structure addressing procedures. The term “Mall” may be substituted for the street type in the address format.

Major street or major collector street

A street, existing or proposed, which serves or is intended to serve as a major traffic way and which is designated on the master street plan as a controlled-access highway, major street, or parkway or other equivalent terms suitable to identify streets comprising the basic structure of the street plan.

Marginal access street

A minor street which is parallel to and adjacent to a major street and which provides access to abutting properties and protection from through traffic.

Meridian street

The north and south directional street (Main Street in Salt Lake City, Salt Lake County) which benchmarks the permanent origin of the Countywide Grid System and provides a datum point from which the coordinates of all other streets and legal situs addresses are calculated (see “Baseline Street”).

Minor street

A street, existing or proposed, which is supplementary to a collector or major street and of limited continuity, which serves or is intended to serve the local needs of a neighborhood.

Numerical freedom

The range of possible numbers which comprise the interval between frontage numbers for a given frontage scale and which may be used to interpolate and assign additional frontage numbers for high density development.

Numerical street name

The assignment of an alphabetic name with numeric value to a street (e.g. Second Ave).

Official (street) map

Any map adopted by a municipality or Salt Lake County under the provisions of state law, to include Master Street Plans labeled “Master Street Plan” of the local governments in the county, including maps and reports or both, which have been approved by the respective municipal and county planning commissions as required by law.

Parcel of land

A quantity of land, in the possession of, owned by, or recorded as the property of the same claimant or person.

Phonetic name duplication

The duplication of street names which have similar or identical pronunciations, but are spelled differently (e.g. Sarah Ridge Ct and Sara Ridge Ct).

Private rights-of-way

Streets which are retained and maintained under the ownership of private individuals and may be intended for both private and public use.

Public rights-of-way

Streets which are dedicated for perpetual public use and are administered and maintained by the governing entities in which they are located.


An architecturally unified group of commercial establishments in multiple structures built on a common site which is planned, developed, owned and managed as an operating unit. The term “Square” may be abbreviated and substituted with a street type in the address format with further identification according to sub-structure addressing procedures.


Any land that is divided, resubdivided or proposed to be divided into two or more lots, parcels, sites, units, plots or other division of land for the purpose, whether immediate or future, for offer, sale, lease or development as recorded in the office of the county recorder under a unique name to identify one subdivision from another.

Subsidiary street name duplication

A street name given to a dead end or cul-de-sac street which duplicates the name of a parent street to which it intersects, and is valid when only one subsidiary name is used and when it intersects relatively perpendicular to the parent street and does not have frontage numbers in the same range or direction as those along the entire length of the parent street (e.g. Vinecrest Dr and Vinecrest Cir).

Sub-parcel identification

A location address descriptor which establishes a one-to-one correspondence for addressing multiple structures on a single parcel of land under the same or separate ownership.

Sub-structure suffix

The last component of a legal situs address which is an alphabetical or numeric code used to identify a one-to one correspondence between a building and high density occupancy structures within the building such as suites, rooms, apartments, and condominium units.
