As the first subject of 1931 research program of the Harvard University School of City Planning, a study of zoning which promises to be valuable to landowner, realtor, banker and owner of residential property is being directed by one of the most widely-known city planning engineers in the country, Harland Bartholomew.

The title of the study is "Land Areas Used for Various Purposes by Urban Populations: Determination of Percentages of Land Use as an Aid to Scientific Zoning Practice." Bartholomew is the president of the National Conference on City Planning, and past-president of the American City Planning Institute, as well as the resident City Plan Engineer of St. Louis.

He has studied and will study a large number of American cities for the purposes of this piece of research. As their consulting engineer, he has already treated a great many American cities. Among the cities for which he has prepared zoning or planning studies are, Washington, D. C., New Orleans, St. Louis, Los Angeles, Memphis, Vancouver, Louisville, Utica and Schenectady.

The primary purpose of the research is the collection and organization of data on the use of land as a basis for scientific zoning, especially in the allocation of areas for future uses, both as to location and amount. Among the other values of the investigation are included the encouragement of adequate judicial cooperation, through the development of zoning as a more exact science; and the clarification of the laws of supply and demand which govern city building.

Computations will be made of the actual areas and the amount of frontage in use for various purposes in both self contained and satellite cities. It will be the object of the study to discover the general relationships between population and the amount of land used for various purposes and to determine whether these land uses have definite relations, one to another.
