He fashioned this design after already-established American cities in the East. Following this uniform pattern, the standard layout for Mormon villages throughout the Utah Territory included open land for public buildings, uniform spacing and setback for all buildings and a central square of 10 acres. Major streets of 100-foot widths radiate to the north, south, east and west from the central point in each community. In Salt Lake City, the center point is the LDS Temple. The streets around Temple Square are called, respectively, North Temple, South Temple, East Temple and West Temple.
Horses are still a viable means of transport in some Southwestern Utah areas.
From there, streets to the north and south of the main street of each village are called First North Street or First South Street, Second North Street or Second South Street, Third North Street or Third South Street and so on. North and south streets run parallel to each other. First West Street is 100 West, Second East Street is 200 East, Fifth West Street is 500 West, etc. East and west streets also are parallel to each other. So a typical Utah street address might be 250 W. 2000 South.
