While the opening up of the city and the loss of neighborhood identity was not universally lamented, many planners, sociologists, and social reformers reacted to the decline by trying to plan the neighborhood back into existence. Essentially the response to industrial capitalism was to apportion cities into manageable units and subunits—segmented, patterned, sorted into equal-size circles, squares, or hexagons at regular intervals, nested into hierarchical arrangements, often with mathematical precision. The quest for order and control manifested as the neighborhood unit—an urban partitioning that even ancient cities had practiced. In the 19th century, garden cities, model villages, and other idealized units were the more immediate precursors of the 20th-century version: relatively self-contained neighborhoods that had access to services, social life, and nature.
