Commerce and industry

Tacoma is the home of several international companies including staffing company True Blue Inc. (formerly Labor Ready), lumber company Simpson and the food companies Roman Meal and Brown and Haley.
Frank C. Mars founded Mars, Incorporated in 1911 in Tacoma.
Beginning in the 1930s, Tacoma became known for the "Tacoma Aroma", a distinctive, acrid odor produced by paper manufacturing on the industrial tide flats. In the late 1990s, Simpson Tacoma Kraft reduced total sulfur emissions by 90%. This largely eliminated the problem; where once the aroma was ever-present, it is now only noticeable occasionally downtown, primarily when the wind is coming from the east.
U.S. Oil and Refining operates an oil refinery on the tide flats in the Port of Tacoma. Built in Tacoma in 1952, it currently refines 39,000 barrels of petroleum per day.
The Tacoma Mall is the largest shopping center in Tacoma. It is owned by Simon Property Group. Anchor tenants include JC Penney, Sears, Macy's, and Nordstrom.
An economic setback for the city occurred in September 2009 when Russell Investments, which has been located in downtown Tacoma since its inception in 1936, announced it was moving its headquarters to Seattle along with several hundred white collar jobs.^[45]
Hospitals in Tacoma are operated by MultiCare Health System and Franciscan Health System. Hospitals include MultiCare Tacoma General Hospital, Mary Bridge Children's Hospital, MultiCare Allenmore Hospital and St. Joseph Medical Center.

Transportation

Tacoma's system of transportation is based primarily on the automobile. The majority of the city has a system of gridded streets oriented in relation to A Street (one block east of Pacific Avenue) and 6th Avenue or Division Avenue, both beginning in downtown Tacoma. Within the city, and with a few exceptions, east-to-west streets are numbered and north-to-south streets are given a name or a letter. Some east-to-west streets are also given names, such as S. Center St. and N. Westgate Blvd. Streets are generally labeled "North", "South", "East", or "North East" according to their relationship with 6th Avenue or Division Avenue (west of 'Division Ave' '6th Avenue' is the lowest-numbered street, making it the dividing street between "North" and "South"), 'A' Street (which is the dividing line between "East" and "South"), or 1st Street NE (which is the dividing line between "East" and "North East"). This can lead to confusion, as most named streets intersect streets of the same number in both north and south Tacoma. For example, the intersection of South 11th Street and South Union Avenue is just ten blocks south of North 11th Street and North Union Avenue.
To the east of the Thea Foss waterway and 'A' Street, streets are similarly divided into "East" and "Northeast", with 1st Street NE being in-line with the Pierce-King county line. "North East" covers a small wedge of Tacoma and unincorporated Pierce County (around Browns Point and Dash Point) lying on the hill across the tideflats from downtown. Tacoma does have some major roads which do not seem to follow any naming rules. These roads include Schuster Pkwy, Pacific Ave, Puyallup Ave, Tacoma Mall Blvd, Marine View Dr (SR 509), and Northshore Pkwy. Tacoma also has some major roads which appear to change names in different areas (most notable are Tyler St/Stevens St, Oakes St/Pine St/Cedar St/Alder St, and S. 72nd St/S. 74th St). These major arterials actually shift over to align with other roads, which causes them to have the name changed.
This numeric system extends to the furthest reaches of unincorporated Pierce County (with roads outside of the city carrying "East", "West", "North West", and "South West", except on the Key Peninsula, which retains the north-south streets but chooses the Pierce-Kitsap county line as the zero point for east-west streets. Key Peninsula's roads also carry a "KP N" or "KP S" designation at the end of the street name.
In portions of the city dating back to the Tacoma Streetcar Period (1888–1938), denser mixed use business districts exist alongside single family homes. Twelve such districts have active, city-recognized business associations and hold "small town"-style parades and other festivals. The Proctor District, Tacoma, Old Town, Dome, 6th Avenue, Stadium, Lincoln Business District, and South Tacoma Business Districts are some of the more prominent and popular of these and coordinate their efforts to redevelop urban villages through the Cross District Association of Tacoma. In newer portions of the city to the west and south, residential culs-de-sac, four-lane collector roads and indoor shopping centers are more commonplace.
