Planned unit development
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.
The conceptual origins of PUDs date back to the 1926 enactment of the Model Planning Enabling Act of 1925 by the Committee on the Regional Plan of New York, which allowed for the decisions of planning boards and commissions to precede decisions required by local zoning regulations. Specifically, Section 12 of the Model Planning Enabling Act authorized planning boards and commissions to reasonably modify or change development plans and limited average population density and total land area covered by buildings. Similarly, Sections 14 and 15 of the Standard City Planning Enabling Act of 1928 allowed planning commissions to authorize PUDs, upon an agreement between the government and developers on the PUD's design principles and its impact to both the surrounding community and economy.
The physical origins of PUDs are rooted in the increased suburbanization of the mid-twentieth century, during which the oldest forms of PUDs in America appeared shortly after World War II in the Levittown and Park Forest developments. Increased implementation of PUDs arose in response to both the lack of aesthetic variation among suburban homes and the increasing need for higher suburban density to accommodate rising population sizes. PUDs resolved the problems of large-scale, suburban development in multiple, separate land uses were efficiently combined, preserving valuable open space and suburban aesthetics within specific site parameters limitations. The first zoning evidence of PUD was created by Prince George's County, Maryland in 1949, in which the developmental unit consisted of multiple land uses, in contrast to the county's previous commitment to single-land use Euclidean zoning.
The usage of PUDs in new American communities have been, in part, the result of some international influence; British towns, like Reston, England, in the 1950s attempted to increase their economic base through the integration of industrial elements into the area. Though American new communities had to attract industry post-development of residential sectors, American new communities had similar economic needs to these British towns and, consequently, used PUDS to increase the percent of allowed industrial acreage relative to residential and nonresidential acreage.
PUD is a means of land regulation that promotes large scale, site-specific, mixed-use land development. PUDs are a very flexible form of zoning, as compared to Euclidean zoning, in that PUDs promotes innovative and creative design, can promote environmental conservation and affordable housing, clustering and increased density. Where appropriate, this type of development promotes:
Frequently, PUDs take on a variety of forms ranging from small clusters of houses combined with open spaces to new and developing towns with thousands of residents and various land uses.
PUDs are in direct contradiction to the single-type zoning that has traditionally underscored zoning in the United States since the Village of Euclid v. Ambler Realty Co. decision. Within PUDs, zoning becomes much more integrated with multiple land uses and districts being placed on adjacent land parcels. The enactment of the Standard Zoning Enabling Act (SZEA) reinforced that density is considered a regulatory priority, further supporting the development of PUDs through the integration of varying lot sizes, varied building uses, and the mixture of different types of housing.
PUDs combine residential and non-residential uses—like offices, commercial stores, and other services—and attracts a diversified community. Notably, sidewalks and streets of PUDs tend to be more active and safer, both at day and night, and experiences reduced congestion during peak times. Detailed plans and review processes are required to approve development of PUDs, due to the nature of mixing residential and non-residential uses into land areas previously only allowed for single-use; approving a PUD essentially requires a legal rezoning, in which variances and conditional use permits must be cleared by a planning board or commission with regards to the municipality's comprehensive plan.
