At the unveiling on June 21, 1967, James Rouse described Columbia as a planned new city which would avoid the leap-frog and spot development threatening the county. The new city would be complete with jobs, schools, shopping, and medical services, and a range of housing choices. Property taxes from commercial development would cover the additional services with which housing would burden the county. The urban planning process for Columbia included not only planners, but also a convened panel of nationally recognized experts in the social sciences, known as the Work Group. The fourteen member group of white men and one woman, Antonia Handler Chayes, met for two days, twice a month, for half a year starting in 1963.:68 The Work Group suggested innovations for planners in education, recreation, religion, and health care, as well as ways of improving social interactions. Columbia's open classrooms, interfaith centers, and the then-novel idea of a health maintenance organization (HMO) with a group practice of medical doctors (the Columbia Medical Plan) sprung from these meetings. The community's physical plan, with neighborhood and village centers, was also decided. Columbia's "New Town District" zoning ordinance gave developers great flexibility about what to put where, without requiring county approval for each specific project.[citation needed]

Local Area Info: Columbia, Maryland

Columbia is a census-designated place in Howard County, Maryland, United States, and is one of the principal cities of the Baltimore metropolitan area and the Washington metropolitan area. It is a planned community consisting of 10 self-contained villages. It began with the idea that a city could enhance its residents' quality of life. Creator and developer James W. Rouse saw the new community in terms of human values, rather than merely economics and engineering. Opened in 1967, Columbia was intended to not only eliminate the inconveniences of then-current subdivision design, but also eliminate racial, religious and class segregation.[citation needed]

Columbia proper consists only of that territory governed by the Columbia Association, but larger areas are included under its name by the U.S. Postal Service and the Census Bureau. These include several other communities which predate Columbia, including Simpsonville, Atholton, and in the case of the census, part of Clarksville. The census-designated place had a population of 99,615 at the 2010 United States Census. It is the second most populous community in Maryland after Baltimore. More recent estimates by the U.S. Census Bureau's American Community Survey put the population at approximately 103,467 as of 2015.

Columbia was founded by James W. Rouse (1914-1996), a native of Easton, Maryland. In 1935, Rouse obtained a job in Baltimore with the Federal Housing Administration, a New Deal agency whose purpose was to promote home ownership and home construction. This position exposed Rouse to all phases of the housing industry. Later in the 1930s he co-founded a Baltimore mortgage banking business. In the 1950s his company, by then known as James W. Rouse and Company, branched out into developing shopping centers and malls. In 1957 Rouse formed Community Research and Development, Inc. (CRD) for the purpose of building, owning and operating shopping centers throughout the country. Community Research and Development, Inc., which was managed by James W. Rouse and Company, became a publicly traded company in 1961. In 1966, Community Research and Development, Inc. changed its name to The Rouse Company, after it had acquired James W. Rouse and Company in exchange for company stock.

At the unveiling on June 21, 1967, James Rouse described Columbia as a planned new city which would avoid the leap-frog and spot development threatening the county. The new city would be complete with jobs, schools, shopping, and medical services, and a range of housing choices. Property taxes from commercial development would cover the additional services with which housing would burden the county. The urban planning process for Columbia included not only planners, but also a convened panel of nationally recognized experts in the social sciences, known as the Work Group. The fourteen member group of white men and one woman, Antonia Handler Chayes, met for two days, twice a month, for half a year starting in 1963.:68 The Work Group suggested innovations for planners in education, recreation, religion, and health care, as well as ways of improving social interactions. Columbia's open classrooms, interfaith centers, and the then-novel idea of a health maintenance organization (HMO) with a group practice of medical doctors (the Columbia Medical Plan) sprung from these meetings. The community's physical plan, with neighborhood and village centers, was also decided. Columbia's "New Town District" zoning ordinance gave developers great flexibility about what to put where, without requiring county approval for each specific project.[citation needed]
