In urban planning, zoning is a method in which a municipality or other tier of government divides land into "zones", each of which has a set of regulations for new development that differs from other zones. Zones may be defined for a single use, they may combine several compatible activities by use, or in the case of form-based zoning, the differing regulations may govern the density, size and shape of allowed buildings whatever their use. The planning rules for each zone determine whether planning permission for a given development may be granted. Zoning may specify a variety of outright and conditional uses of land. It may indicate the size and dimensions of lots that land may be subdivided into, or the form and scale of buildings. These guidelines are set in order to guide urban growth and development.
Growth management, in the United States, is a set of techniques used by the government to ensure that as the population grows that there are services available to meet their demands. Growth management goes beyond traditional land use planning, zoning and subdivision controls in both the characteristics of development influenced and the scope of government powers used. These are not necessarily only government services. Other demands such as the protection of natural spaces, sufficient and affordable housing, delivery of utilities, preservation of buildings and places of historical value, and sufficient places for the conduct of business are also considered.
Downtown is a term primarily used in North America by English speakers to refer to a city's sometimes commercial, cultural and often the historical, political, and geographic heart. It is often synonymous with its central business district (CBD). Downtowns typically contain a small percentage of a city's employment. Sometimes, smaller downtowns are surrounded by lower population densities and lower incomes than suburbs. It is often distinguished as a hub of public transit and culture.
A residential area is a land used in which housing predominates, as opposed to industrial and commercial areas.
1201 Third Avenue is a 235.31-meter (772.0 ft), 55-story skyscraper in Downtown Seattle, in the U.S. state of Washington. It is the third-tallest building in the city, the eighth-tallest on the West Coast of the United States, and the 97th-tallest in the United States. Developed by Wright Runstad & Company, construction began in 1986 and finished in 1988. 1201 Third Avenue was designed by Kohn Pedersen Fox Associates and The McKinley Architects. The building was the world headquarters of the financial company Washington Mutual from the building's opening until 2006, when the company moved across the street to the WaMu Center.
A setback, in the specific sense of a step-back, is a step-like form of a wall or other building frontage, also termed a recession or recessed story. Importantly, one or more step-backs lowers the building's center of mass, making it more stable. A setback as a minimum one-bay indent across all stories is called a recessed bay or recess and is the more common exterior form of an alcove.
The urban-to-ruraltransect is an urban planning model created by the New Urbanist Andrés Duany. The transect defines a series of zones that transition from sparse rural farmhouses to the dense urban core. Each zone is fractal in that it contains a similar transition from the edge to the center of the neighborhood. The transect is an important part of the New Urbanism and smart growth movements. Duany's firm DPZ has embodied the transect philosophy into their SmartCode generic planning code for municipal ordinances.
A Form-Based Code (FBC) is a means of regulating land development to achieve a specific urban form. Form-Based Codes foster predictable built results and a high-quality public realm by using physical form as the organizing principle, with less focus on land use, through municipal regulations. An FBC is a regulation, not a mere guideline, adopted into city, town, or county law and offers a powerful alternative to conventional zoning regulation.
Height restriction laws are laws that restrict the maximum height of structures. There are a variety of reasons for these measures. Some restrictions serve aesthetic values, such as blending in with other housing and not obscuring important landmarks. Other restrictions may serve a practical purpose, such as height restrictions around airports for flight safety. Height restriction laws for housing have become a source of contention by restricting housing supply, increasing housing costs, and depressing land values.
Build-out is an urban planner’s estimate of the amount and location of potential development for an area. Sometimes called a "lot-yield analysis", build-out is one step of the land use planning process. Evaluation of potential development impacts begins with a build-out analysis.
One Bayfront Plaza is a proposed supertall skyscraper in Miami, Florida, U.S. The building, construction of which has been approved, would stand at 1,049 feet (320 m), with 93 floors, becoming the tallest building in Miami and Florida. One Bayfront Plaza would primarily consist of offices and hotel space, but also would include a retail mall, condominiums, and parking garage on the lower levels, as well as possibly an observation deck at the top. The entire project consists of over 1,400,000 square feet (100,000 m2) of Class A office and hotel space, as well as a total building area of over 4,000,000 square feet (371,612 m2) including the large podium. One Bayfront Plaza is the first skyscraper over 1,000 feet (305 m) to be approved for construction in Miami. The building's primary advocate is real estate developer Tibor Hollo, who has won several awards for his 55 years as a developer in Miami, and is currently the president of Florida East Coast Realty.
The 1916 Zoning Resolution in New York City was the first citywide zoning code in the United States. The zoning resolution reflected both borough and local interests, and was proposed after the Equitable Building was erected in Lower Manhattan in 1915.
Zoning is a law that divides a jurisdiction's land into districts, or zones, and limits how land in each district can be used. In the United States, zoning includes various land use laws enforced through the police power rights of state governments and local governments to exercise authority over privately owned real property.
500 Fifth Avenue is a 60-story, 697-foot-tall (212 m) office building on the northwest corner of Fifth Avenue and 42nd Street in Midtown Manhattan, New York City. The building was designed by Shreve, Lamb & Harmon in the Art Deco style and constructed from 1929 to 1931.
Robert Michael Scarano Jr. is an American architect who works primarily in Brooklyn, New York City. In March 2010, Scarano was barred from submitting plans for new buildings to New York City's Department of Buildings.
A residential cluster development, or open space development, is the grouping of residential properties on a development site to use the extra land as open space, recreation or agriculture. It is increasingly becoming popular in subdivision development because it allows the developer to spend much less on land and obtain much the same price per unit as for detached houses. The shared garden areas can be a source of conflict, however. Claimed advantages include more green/public space, closer community, and an optimal storm water management. Cluster development often encounters planning objections.
A pencil tower is a high-rise building or skyscraper with a very high slenderness ratio that is very tall and thin. There is no universal definition of how slender these buildings are to be categorized, but some definitions of 10:1 or 12:1 ratios and higher have been used.
In architecture, construction, and real estate, floor area, floor space, or floorspace is the area taken up by a building or part of it. The ways of defining "floor area" depend on what factors of the building should or should not be included, such as external walls, internal walls, corridors, lift shafts, stairs, etc. Generally there are three major differences in measuring floor area.
The Height of Buildings Act of 1899 was a U.S. height restriction law passed by the 55th Congress in response to advancements in construction technology, specifically the use of iron and steel frames, along with thin veneer facades, which made it possible to build lighter, and consequently much taller buildings. Residents of densely populated cities, including Washington D.C., felt that the new technology was untested and steel-framed structures may suffer "serious and fatal defects" due to corrosion from steam pipes and electrical wiring – another relatively recent advancement. They believed that these new tall buildings would ultimately collapse. In an 1899 Senatorial Report, Senator Warren Curtis speculated that, "the life of these structures might not be more than seventy-five years."
Missing middle housing refers to a lack of medium-density housing in the North American context. The term describes an urban planning phenomenon in Canada, the United States, Australia and more recent developments in industrialised and newly industrialising countries due to zoning regulations favoring social and racial separation and car-dependent suburban sprawl.
