(ISS). North is at bottom. Salt Lake City has an area of and an average elevation of
above sea level. The lowest point within the boundaries of the city is near the
Jordan River and the
Great Salt Lake, and the highest is
Grandview Peak, at . The city is in the northeast corner of the
Salt Lake Valley surrounded by the Great Salt Lake to the northwest, the steep
Wasatch Range to the east, and
Oquirrh Mountains to the west. Its encircling mountains contain several narrow canyons, including
City Creek,
Emigration,
Millcreek, and
Parley's which border the eastern city limits. The burgeoning population of Salt Lake City and the surrounding metropolitan area, combined with its geographical situation, has led to
air quality becoming a concern. The
Great Basin is subject to strong temperature inversions during the winter, which trap pollutants and decrease the air quality. The Utah Division of Air Quality monitors air quality and issues alerts for voluntary and mandatory actions when pollution exceeds federal safety standards. Protests have been held at the
Utah State Capitol and
Democratic lawmakers have introduced legislation in the
Utah State Legislature to make public transportation free during January and July, when air quality is usually at its worst. The population of the Salt Lake City metropolitan area is projected to double by 2040, putting further pressure on the region's air quality. The Great Salt Lake is separated from Salt Lake City by extensive marshlands and mudflats. The metabolic activities of bacteria in the lake result in a phenomenon known as "lake stink", a scent reminiscent of foul poultry eggs, two to three times per year for a few hours. The Jordan River flows through the city and is a drainage of
Utah Lake that empties into the Great Salt Lake. The highest mountaintop visible from Salt Lake City is
Twin Peaks, which reaches . Twin Peaks is southeast of Salt Lake City in the Wasatch Range. The second-highest mountain range is the Oquirrhs, reaching a maximum height of 10,620 feet (3,237 m) at Flat Top. The east–west-oriented
Traverse Mountains to the south extend to 6,000' (1830m), nearly connecting the Wasatch and Oquirrh Mountains. The mountains near Salt Lake City are easily visible from the city and have sharp vertical relief caused by ancient earthquakes, with a maximum difference of 7,099 feet (2164 m) being achieved with the rise of Twin Peaks from the Salt Lake Valley floor. These faults are related to the regional
Wasatch Fault which runs north–south along the western base of the Wasatch Range and is considered at high risk of producing an earthquake as large as 7.5
magnitude. Catastrophic damage is predicted in the event of an earthquake with major damage resulting from the
liquefaction of the clay- and sand-based soil and the possible permanent flooding of portions of the city by the Great Salt Lake. On March 18, 2020, a 5.7 magnitude
earthquake, the largest in the Salt Lake City area in modern times, hit
Magna, just southwest of Salt Lake City, causing some minor damage throughout the valley. Damage in Salt Lake City was especially evident in historic brick homes—
unreinforced masonry buildings—such as the 1892 Sears mansion which required demolition after the earthquake. The Warm Springs Fault and the East Bench Fault, offshoots of the Wasatch Fault, were found in 2021 to connect underneath Salt Lake City, increasing the risk of major metropolitan damage from an earthquake. A year later, a fault segment was found at the southern edge of the convention center, and expansion plans were halted until more earthquake fault studies could be completed.
Layout of Salt Lake City, circa 1870s The city, as well as the
county, is laid out on a
grid plan. Most major streets run very north–south and east–west. The grid's origin is the southeast corner of Temple Square, the block containing the Salt Lake Temple; the north–south axis is Main Street; and the east–west axis is South Temple Street. Addresses are
coordinates within the system (similar to
latitude and
longitude). Odd and even address numbering depends on the quadrant of the grid in which an address is located. The rule is: When traveling away from the grid center (Temple Square) or its axes (Main Street, South Temple Street), odd numbers will be on the left side of the street. A common explanation for the unusually wide streets of Salt Lake City is that Brigham Young wanted a wagon with a team of oxen to be able to turn around. However, Young was never recorded giving this directive. Joseph Smith, founder of the Latter Day Saint movement, planned the layout in the "
Plat of the City of Zion" (intended as a template for Mormon towns wherever they might be built). This plan included streets wide, and may be the source of the unusual width. These wide streets and grid pattern are typical of other Mormon towns of the pioneer era throughout the West. Though the nomenclature may initially confuse new arrivals and visitors, most consider the grid system an aid to navigation. The grid system allows streets to be identified numerically according to their distance from the center axes—for example, addresses on 100 East are one block east of Main Street. Most streets use this numeric system exclusively; however, some historic streets retain traditional names. State Street, for instance, runs along the same alignment as what would be designated '100 East' under the numeric system, but has retained its historical name Other streets have honorary names, such as the western portion of 300 South, named "Adam Galvez Street" (for a local Marine corporal killed in action) or others honoring
Rosa Parks,
Martin Luther King Jr.,
César Chávez,
Harvey Milk, and
John Stockton. These honorary names appear only on street signs and cannot be used in postal addresses. Convention Center In the
Avenues neighborhood, north–south streets are given letters of the alphabet, and east–west streets are numbered in blocks, smaller than those in the rest of the city. Smith's Plat of Zion specified the city was to be developed into 135 lots. However, the blocks in Salt Lake City became irregular during the late 19th century when
the Church of Jesus Christ of Latter-day Saints lost authority over growth and before the adoption of zoning ordinances in the 1920s. The original blocks allowed for large garden plots, and many were supplied with irrigation water from ditches that ran approximately where modern curbs and gutters would be laid. The original water supply was from
City Creek. Subsequent development of water resources was from successively more southern streams flowing from the mountains east of the city. Some old irrigation ditches are still visible in the eastern suburbs, or are still marked on maps, years after they were gone. There are still some canals that deliver water as required by water rights. Many lots, in Salt Lake City and surrounding areas, have irrigation water rights attached to them. Local water systems, in particular Salt Lake City Public Utilities, have a tendency to acquire or trade for these water rights. These can then be traded for culinary water rights to water imported into the valley. At its peak, irrigation in the valley comprised over one hundred distinct canal systems, many originating at the Jordan Narrows at the south end of the valley. Water and water rights were important in the 19th and early 20th centuries. As heavy agricultural usage changed into a more urban and suburban pattern, canal water companies were gradually replaced by culinary water systems.
Cityscape . Notable buildings from left to right:
Salt Lake Temple,
Hotel Utah,
Kearns Building,
Capitol Theatre,
Walker Center,
City and County Building, Boston and Newhouse Buildings, and
Hotel Newhouse. Downtown Salt Lake City has been a hub of commerce for the
Intermountain West and its architecture reflects this history.
Main Street, which was the primary commercial avenue for the city in the late 19th and early 20th centuries, anchors the historic core of the downtown area that begins at the
Salt Lake Temple and concludes at the
City and County Building. Halfway between those two structures, the
Walker Center, at the corner of Main and 200 South, was built in 1912 and was the tallest building between
Chicago and
San Francisco upon its completion. Other extant pre-war structures include the
Kearns Building,
Hotel Monaco, the First Security Building, the
Joseph Smith Memorial Building (formerly Hotel Utah), the Boston and Newhouse Buildings, the
Utah State Capitol, and the
Clift Building. Salt Lake City has two historic passenger rail depots, the
Denver and Rio Grande Western Depot and the
Union Pacific Depot, the latter of which now anchors the
Gateway district. Salt Lake City lost many significant structures to forces such as
urban renewal in the 20th century, including the
Dooly Building, designed by
Louis Sullivan, the
Hotel Newhouse, and the
Salt Lake Theatre. at the corner of Main Street and 100 South showing the base of the newly constructed 111 Main office tower and
Eccles Theater.
TRAX runs along Main through the heart of the city. After a period of stagnation in the era of
urban sprawl, and with the construction of
TRAX in the late 1990s and the
City Creek Center in the early 2010s, downtown Salt Lake City is experiencing a period of revival. Empty lots and older structures are in the process of being redeveloped into apartment and office towers and the city has begun to close Main Street to automobile traffic on summer weekends to encourage pedestrian activity and business. More than 5,000 new residential units are planned or under construction for the downtown area as of April 2021 and many new breweries and restaurants have opened in the last decade. Regent Street, which in the early 20th century was the city's
red-light district, has recently been redeveloped with the notable additions of the 2,468-seat
Eccles Theater and 111 Main, an adjacent 24-story office building. A distinctive feature of Salt Lake City's cityscape is its very large block sizes, which are 660 feet square and separated by streets 132 feet wide, making them the largest in the United States. This and the resulting development patterns gives the city and its buildings a unique sense of scale but also a distinct challenge to urban
walkability, with many streets boasting six lanes for automobile traffic. On the other hand, the extra-wide streets have made the addition of dedicated transit lanes and light rail more feasible and many streets are now being redesigned with features such as protected bike lanes, linear parks, and even spaces for urban development within the medians. The city also encourages new projects to incorporate mid-block walkways and other scale-mitigation strategies into planning to promote pedestrian engagement.
Neighborhoods Salt Lake City has many distinct neighborhoods. There is a general east–west socioeconomic divide. The eastern neighborhoods of the city, such as
the Avenues,
9th & 9th,
Yalecrest, Federal Heights, and
Sugar House tend to be more affluent. These districts are popular with professionals, families, and students due to their proximity to Downtown, the
University of Utah, commercial precincts, and the Wasatch foothills. The western neighborhoods of the city, such as
Poplar Grove,
Rose Park, and
Glendale tend to be more working-class and ethnically diverse and are popular with immigrants and young people. This divide is a result of the railroad being built in the western half as well as panoramic views from inclined ground in the eastern portion. Housing is more economically diverse on the west side, which results in
demographic differences.
Interstate 15 was also built in a north–south line, further dividing east and west sides of the city.
Sugar House, in southeastern Salt Lake City, has a reputation as an older neighborhood with small shops in the center. Sugar House is an area which has been the focus of redevelopment efforts such as the
UTA S-Line Streetcar. In late 2015 there were approximately 900 apartment units either recently built or under construction in the Sugar House area, with an additional 492 units proposed. Northeast of Downtown is The Avenues, a neighborhood outside of the regular grid system on smaller blocks. The area between 6th Avenue to South Temple Street is a Historical District that is nearly entirely residential, and contains many historical Victorian era homes. Recently the Avenues is becoming known for restaurants and shops opening in old retail space mixed within the community. The Avenues are situated on the upward-sloping bench in the foothills of the Wasatch Range, with the earlier built homes in the lower elevation. The Avenues, along with Federal Heights, just to the east and north of the
University of Utah, and the
Foothill area, south of the university, contain gated communities, large, multimillion-dollar houses, and panoramic views of the valley. Many consider this some of the most desirable real estate in the valley. In addition to larger centers like Sugar House and Downtown, Salt Lake City contains several smaller neighborhoods, each named after the closest major intersection. Two examples are the
9th and 9th (at the intersection of 900 East and 900 South Streets) and 15th & 15th (at the intersection of 1500 East and 1500 South Streets) neighborhoods. These areas are home to foot-traffic friendly, amenities-based businesses such as art galleries, clothing retail, salons, restaurants and coffee shops. During the summer of 2007, 9th and 9th saw sidewalk and street improvements as well as an art installation by Troy Pillow of Seattle, Washington inspired by the 9 Muses of Greek myth, thanks in part to a monetary grant from Salt Lake City. Many of the homes in the valley date from pre–World War II times, and only a select few areas, such as Federal Heights and the East Bench, as well as the far west side, including parts of Rose Park and Glendale, have seen new home construction since the 1970s.
Climate of Utah Salt Lake City has a
humid continental climate (
Dsa), while western parts may experience a
Mediterranean climate (
Csa), as summers are dry and hot and winters are cold and wet, but rarely frigid. The eastern parts of the city are also under a Mediterranean climate when using the isotherm. Late summer and early fall monsoonal activity can keep precipitation fairly consistent throughout the year aside from early to mid summer when rain is minimal. The temperature of the Salt Lake City area is mediated by its unique geography, generally keeping highs and lows from reaching extremes. The primary source of precipitation in Salt Lake City is massive storms that move in from the
Pacific Ocean along the
jet stream from October to May. In mid-to-late summer, when the jet stream retreats far to the north, precipitation mainly comes from afternoon
thunderstorms caused by
monsoon moisture moving up from the
Gulf of California. Although rainfall can be heavy, these storms are usually scattered in coverage and rarely severe. However, downtown was hit by an
F2 tornado on August 11, 1999, killing 1 person, injuring 60, and causing $170 million in damage. The remnants of
tropical cyclones from the East Pacific can rarely reach the city during Fall. The remnants of
Hurricane Olivia helped bring the record monthly precipitation of in September 1982. 1983 was the wettest year on record, with , while 1979 was the driest, when were recorded. Spring
snowmelt from the surrounding mountains can cause localized stream flooding during late spring and early summer, the worst examples being in 1952 and especially 1983, when City Creek burst its banks, forcing city engineers to convert several downtown streets into waterways. Snow falls on average from November 6 to April 18, producing a total average of , although measurable snow has fallen as early as September 17 and as late as May 28. The snowiest season was 1951–52, with , while the least snowy season was in 1933–34. The snowiest month on record was January 1993, in which were recorded. The nearby Great Salt Lake is a significant contributor to precipitation in the city. The lake effect can enhance rain from summer thunderstorms and produces
lake-effect snow approximately 6 to 8 times per year, some of which can produce prodigious snowfall amounts. It is estimated about 10% of the annual precipitation in the city can be attributed to the lake effect. Salt Lake City features large variations in temperatures between seasons. During summer, there are an average of 56 days per year with temperatures of at least , 23 days of at least , and 9 days of . However, average daytime July humidity is only 22%. Winters are quite cold but rarely frigid. While an average of 127 days drop to or below freezing, and 26 days with high temperatures that fail to rise above freezing, the city only averages 6.3 days at or below . The record high temperature is , which occurred first on July 26, 1960, July 13, 2002, June 16, 2021, July 17, 2022, and most recently September 7, 2022, while the record low is , which occurred on February 9, 1933. This same effect will also occasionally play a role in the summer months, causing
tropospheric ozone to peak in July & August, but in 2015 it started at the beginning of June. In 2016 Salt Lake's air quality was ranked 6th worst in the nation by the American Lung Association. It received an F grade for both ozone and particulate matter. Particulate pollution is considered especially dangerous, as the tiny pollutants can lodge deep in lung tissue. Both ozone and particulate pollution are associated with increased rates of strokes, heart attacks, respiratory disease, cancer and premature death. Outdoor air particulates have been associated with low and very low birth weight, premature birth, congenital defects, and death. Severe drought and water diversions have shrunk the Great Salt Lake by two-thirds and reduced it to its lowest recorded levels, resulting in hundreds of square miles of dry lake bed and exposing millions of people living in the fast-growing metropolitan region to dust storms laced with
arsenic and other toxic chemicals. Around 65% of the diverted water goes to agriculture, but demand for water is soaring as Utah's population grows. At 217.5 acres, This is the Place Heritage Park re-creates typical 19th-century pioneer life and contains over 50 restored or replicated historical buildings.
This is the Place Monument also is located within the park, marking the end of the Mormon trail.
Sugar House Park is the second largest park in Salt Lake City at and is a part of the Salt Lake County park system. The park is known for its large, rolling hills surrounding a pond with fountains. It was also the site of an annual Fourth of July fireworks display until 2018.
Red Butte Garden and Arboretum, in the
foothills of Salt Lake City, features many different exhibits and also hosts many musical concerts. It is operated by the University of Utah.
City parks Salt Lake City has a system of 85 municipal parks. Some of the most notable, other than those mentioned above, are: •
Allen Park () developed as a bird sanctuary •
Liberty Park () is one of the city's oldest parks, having been established in 1881, and features a small lake with two islands and the Tracy Aviary. The park is home to a large number of birds, both wild and in the aviary. •
City Creek Park () • Pioneer Park () • Lindsey Gardens () •
Gilgal Garden () •
Jordan Park () is home to the
International Peace Gardens. •
Bonneville Shoreline Trail is a popular hiking and biking nature trail which spans through the foothills of the Wasatch Front. ==Demographics==
