Millcreek

History

Early settlers of the Millcreek area in 1848 included Mary Fielding Smith (widow of Hyrum Smith) and her children, including Joseph F. Smith. The area remained essentially rural in character until after World War II. As postwar suburban growth spilled south over the Salt Lake City limits, the area was not annexed by the city and remained unincorporated. By the 1980s, most of the area now in Millcreek was built out and known by various names, including East Mill Creek, Canyon Rim and Mount Olympus. In the 2000 census, the area was divided among four CDPs for statistical purposes, the westernmost of which was designated Millcreek CDP. The population of this CDP was 30,377 at the 2000 census, and had a total area of 4.9 square miles (12.8 km2). Canyon Rim CDP, East Millcreek CDP, and Mount Olympus CDP were consolidated with Millcreek CDP in the 2010 census, doubling its population to 62,139. Salt Lake County created Millcreek Township in 2002 as an administrative subentity that included the populated CDPs as well as undeveloped Mill Creek Canyon in the Uinta-Wasatch-Cache National Forest immediately to the east. The township was created to give residents of the area more local control over planning and prevent annexations by neighboring cities. As other communities south of Salt Lake City were incorporated in the 1990s and 2000s, Millcreek remained as the most populous unincorporated area of Salt Lake County. Residents considered a number of options for their future, including incorporation, which would make it the county's fifth-largest city. Amalgamation with neighboring South Salt Lake was also proposed, which would have combined South Salt Lake's commercial and industrial base with Millcreek's heavily residential character, creating a city of over 80,000.…

Geography

Suburban in character, Millcreek is wedged between Salt Lake City and South Salt Lake on the north and Murray and Holladay on the south. Millcreek residents typically identify with Salt Lake City, which is designated by the U.S. Postal Service as the default place name for mailing addresses in the area. Millcreek is a recognized place name for addresses in the ZIP codes 84106, 84107, 84109, 84117, and 84124. The city is organized into four community councils, Canyon Rim, East Mill Creek, Millcreek, and Mount Olympus, roughly corresponding to the former CDPs. This climatic region is typified by large seasonal temperature differences, with warm to hot summers and cold (sometimes severely cold) winters. According to the Köppen Climate Classification system, Millcreek has a humid continental climate, abbreviated "Dfb" on climate maps. Historically distinct communities from which Millcreek developed include: *Canyon Rim, located in the northeastern Millcreek, which developed during the post-World War II period as agricultural property was subdivided for housing. The Canyon Rim name came into broader use as homes were constructed near the rim of Parleys Hollow during the 1950s. *East Mill Creek, which includes residential areas near the mouth of Mill Creek Canyon and some of the city's earliest settlement areas. Farms and orchards historically characterized portions of the community before suburban subdivision accelerated during the 20th century. *The western and central portions of Millcreek, which contain denser residential and commercial development.
