A transition zone geographically links two urban areas, possessing characteristics of each but belonging to neither. In an older city, as you travel into a transition zone from a place that is defined by a consistent pattern of land use and development, the pattern is disrupted; the size, scale, design, use, and occupancy of land and buildings become more diverse and less organized. Development in many transition zones predated zoning laws. In these places, houses may share blocks with factories, garages, warehouses, stables, or scrap yards.
