Urban development plans have significant potential impacts on affected environment according to the various activities and due to their different construction and operation phases. Establishment and development of the new-established Municipality of Tehran District-22, with about 10,000 hectares area has been planned as the last limit of continuous extension of Great Tehran and as the largest urban city of the country. It is based on the general lay out of Tehran master development plan, ratified in 1970 and 1991. In terms of current facilities, it has been anticipated necessary spaces to establish various activities including residential, commercial and urban services, establishing green spaces, man-made lake and other necessary infrastructures of urban development. Griding method was used in order to determine the environment vulnerability of the development plan of the region. In this method, the studied district has been divided into 1 to 10 square kilometers grids. To improve the accuracy of the study, the grids dimension is smaller than the common size. After griding, the most appropriate layers out of the required layers have been used to determine the vulnerability. These layers are, land slope, geographical aspect, pedology, geology, plant density and ground water vulnerability. The limited codes of each layer have also been defined. Summary of the above-mentioned layers results have been analyzed in the map form 1:50,000 scale by Arc-View software in GIS system in order to determine the specification of impact units. After the determination of limitation, the most prevailing limited code of each grid was selected. The obtained results were transferred to excel program and the final amount of vulnerability were then calculated by using equation ? =? (a-b)/4. The final vulnerability was substitute by each grid code as a new data and the last map of vulnerability was set. Regarding to this map at the studied region affected by current limitation of environmental condition, the north part of the district especially A9, B10, B11, B12, C9, C11, C18, D12 and E14 showed the highest amount of vulnerability. According to the final vulnerability map, it is distinguished that the north parts of the district mainly in parts 1 or 2 vulnerability codes have had high vulnerability.
