The perspective of urban fabric transformation is formulated in connection with the reduction of the influence of industrial factors and the development of information-rich society. This tendency transforms large functional areas of the industrial city into local residential clusters with a pedestrian accessibility of up to 2 km. The aggregate of such clusters of universal pedestrian accessibility (“urban villages”), which is superimposed by the growth of local self-organization and vertical initiatives, may cause partial revision of the functions of city-wide management. A key element for the practical implementation of the impulse development strategy of the city in the 21st century is the prediction of the development of a basic urban unit in a post-industrial city, which in this work is called the local cluster. The phenomenon of impulse development of urban fabric is analysed, and the system of laws and principles that transform urban complexes into post-industrial ones is outlined. It has been found that the impulse strategy, in contemporary conditions, should be made of two components and contain both city-wide and local levels of management and modeling. The level of local clusters, which is being discussed herein, involves the presence of a combination of impulse factors, the content and names of which are presented in this work.
