Mixed-use development is a type of urban development, urban design, urban planning and/or a zoning classification that blends multiple uses, such as residential, commercial, cultural, institutional, or entertainment, into one space, where those functions are to some degree physically and functionally integrated, and that provides pedestrian connections. Mixed-use development may be applied to a single building, a block or neighborhood, or in zoning policy across an entire city or other administrative unit. These projects may be completed by a private developer, (quasi-) governmental agency, or a combination thereof. A mixed-use development may be a new construction, reuse of an existing building or brownfield site, or a combination.
Use in North America vs. Europe Traditionally, human settlements have developed in mixed-use patterns. However, with industrialization, governmental zoning regulations were introduced to separate different functions, such as manufacturing, from residential areas. Public health concerns and the protection of property values stood as the motivation behind this separation. In the United States, the practice of zoning for single-family residential use was instigated to safeguard communities from negative externalities, including air, noise, and light pollution, associated with heavier industrial practices. These zones were also constructed because of racial and class tensions. The heyday of separate-use zoning in the United States came after World War II when planner and New York City Parks Commissioner, Robert Moses, championed superhighways to break up functions and neighborhoods of the city. The antithesis to these practices came from activist and writer, Jane Jacobs, who was a major proponent of mixed-use zoning, believing it played a key role in creating an organic, diverse, and vibrant streetscape. These two figures went head-to-head during much of the 1960s. Since the 1990s, mixed-use zoning has once again become desirable as it works to combat urban sprawl and increase economic vitality. In most of Europe, government policy has encouraged the continuation of the city center's role as a main location for business, retail, restaurant, and entertainment activity, unlike in the United States where zoning actively discouraged such mixed use for many decades. In England, for example, hotels are included under the same umbrella as "residential," rather than commercial as they are classified under in the US. France similarly gravitates towards mixed-use as much of Paris is simply zoned to be "General Urban," allowing for a variety of uses. Even zones that house the mansions and villas of the aristocrats focus on historical and architectural preservation rather than single family zoning. Single family zoning is also absent in Germany and Russia where zoning codes make no distinction between different types of housing. America's attachment to private property and the traditional 1950s suburban home, as well as deep racial and class divides, have marked the divergence in mixed-use zoning between the continents. As a result, much of Europe's central cities are mixed use "by default" and the term "mixed-use" is much more relevant regarding new areas of the city where an effort is made to mix residential and commercial activities – such as in Amsterdam's Eastern Docklands.
Contexts Expanded use of mixed-use zoning and mixed-use developments may be found in a variety of contexts, such as the following (multiple such contexts might apply to one particular project or situation): as part of smart growth planning strategies in traditional urban neighborhoods, as part of urban renewal and/or infill, i.e., upgrading the buildings and public spaces and amenities of the neighborhood to provide more and/or better housing and a better quality of life—examples include Barracks Row in Washington, D.C., and East Liberty, Pittsburgh in traditional suburbs, adding one or more mixed-use developments to provide a new or more prominent "downtown" for the community–examples include new projects in downtown Bethesda, Maryland, an inner suburb of Washington, D.C., and the Excelsior & Grand complex in St. Louis Park, Minnesota, an inner suburb of Minneapolis greenfield developments, i.e., new construction on previously undeveloped land, particularly at the edge of metropolitan areas and in their exurbs, often as part of creating a relatively denser center for the community—an edge city, or part of one, zoned for mixed use, in the 2010s often labeled "urban villages" (examples include Avalon in Alpharetta, Georgia, and Halcyon in Forsyth County, Georgia, at the edge of the Atlanta metropolitan area) the repurposing of shopping malls and intensification of development around them, particularly as many shopping malls' retail sales, and ability to rent space to retailers, decrease as part of the 2010s retail apocalypse Any of the above contexts may also include parallel contexts such as:
Transit-oriented development—for example in Los Angeles and San Diego, where the cities made across-the-board zoning law changes permitting denser development within a certain distance of certain types of transit stations, with the primary aim of increasing the amount and affordability of housing Older cities such as Chicago and San Francisco have historic preservation policies that sometimes offer more flexibility for older buildings to be used for purposes other than what they were originally zoned for, with the aim of preserving historic architecture
Benefits
Economic Mixed-use developments are home to significant employment and housing opportunities. Many of these projects are already located in established downtown districts, meaning that development of public transit systems is incentivized in these regions. By taking undervalued and underutilized land, often former heavy industrial, developers can repurpose it to increase land and property values. These projects also increase housing variety, density, and oftentimes affordability through their focus on multifamily, rather than single-family housing compounds. A more equal balance between the supply and demand of jobs and housing is also found in these districts.
