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 the USA 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 variance is a deviation from the set of rules a municipality applies to land use and land development, typically a zoning ordinance, building code or municipal code. The manner in which variances are employed can differ greatly depending on the municipality. A variance may also be known as a standards variance, referring to the development standards contained in code. A variance is often granted by a Board or Committee of adjustment.
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.
In land use, a setback is the minimum distance which a building or other structure must be set back from a street or road, a river or other stream, a shore or flood plain, or any other place which is deemed to need protection. Depending on the jurisdiction, other things like fences, landscaping, septic tanks, and various potential hazards or nuisances might be regulated and prohibited by setback lines. Setbacks along state, provincial, or federal highways may also be set in the laws of the state or province, or the federal government.
A planned unit development (PUD) is a type of flexible, non-Euclidean zoning device that redefines the land uses allowed within a stated land area. PUDs consist of unitary site plans that promote the creation of open spaces, mixed-use housing and land uses, environmental preservation and sustainability, and development flexibility. Areas rezoned as PUDs include building developments, designed groupings of both varied and compatible land uses—such as housing, recreation, commercial centers, and industrial parks—within one contained development or subdivision. Developed areas vary in size and by zoned uses, such as industrial, commercial, and residential. Other types of similar zoning devices include floating zones, overlay zones, special district zoning, performance-based codes, and transferable development rights.
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.
SmartCode is a unified land development ordinance template for planning and urban design. Originally developed by Duany Plater-Zyberk & Company, this open source program is a model form-based unified land development ordinance designed to create walkable neighborhoods across the full spectrum of human settlement, from the most rural to the most urban, incorporating a transect of character and intensity within each. It folds zoning, subdivision regulations, urban design, and basic architectural standards into one compact document. Because the SmartCode enables community vision by coding specific outcomes that are desired in particular places, it is meant to be locally calibrated by professional planners, architects, and attorneys.
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.
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.
SouthField is a form-based code planned community located on the former South Weymouth Naval Air Station in South Weymouth, Massachusetts. It is a 1,400-acre (6 km2) site 12 miles (19 km) south of Boston that overlaps three towns: Weymouth, Abington, and Rockland. Developed by LNR Property Corporation, SouthField will contain 2,855 housing units and up to 2,000,000 square feet (186,000 m2) that include single-family homes, apartments, and townhouses. The site will also have up to 1.7 million square feet of commercial development, a 45-acre recreational facility, an 18-hole golf course, walking trails and 1,000 acres of undeveloped land.
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.
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.
Exclusionary zoning is the use of zoning ordinances to exclude certain types of land uses from a given community, especially to regulate racial and economic diversity. In the United States, exclusionary zoning ordinances are standard in almost all communities. Exclusionary zoning was introduced in the early 1900s, typically to prevent racial and ethnic minorities from moving into middle- and upper-class neighborhoods. Municipalities use zoning to limit the supply of available housing units, such as by prohibiting multi-family residential dwellings or setting minimum lot size requirements. These ordinances raise costs, making it less likely that lower-income groups will move in. Development fees for variance, a building permit, a certificate of occupancy, a filing (legal) cost, special permits and planned-unit development applications for new housing also raise prices to levels inaccessible for lower income people.
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.
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 industrialized and newly industrializing countries due to zoning regulations favoring social and racial separation and car-dependent suburban sprawl.
