Perception of urban development process in urban planning and management of sustainable urban development is important. In this paper physical and spatial development of Varzaneh city is studied and, after recognition of its potentials and restricts with using Boolean model and overlaying in GIS and also calculation of requisite space for the added future population optimum strategies for future development is suggested. The method of the research is descriptive-analytic and method of data gathering is documental-library. In order for completion of data and monitoring urban development of Varzaneh, we have accomplished field study and group interview with Varzaneh people. The results of the research indicated that initially urban development of Varzaneh has been was self-growing and have happened around the center of the city, but because of existing agric cultural lands. It was impossible to develop the core and the new city along with the old city has been developed (they separate from each other by the river). In new developing plans direction of development is to the north. The results also signified that not only it’s not necessary to expand the city for future development even when population are threefold rather than now but also altitudinal development of city is possible due to the free lands, urban sprawl and one- floor buildings.
